  • 6. LESSON 1. ARE YOU REALLY HEALTHY? Lesson Targets: Discuss the concept of holistic health  Explain the different dimensions of holistic health (physical, mental/intellectual, emotional, social, moral-spiritual)  Analyze the interplay among the health dimensions in developing holistic health.  Practice health habits to achieve holistic health. Something to Ponder On When you were younger, you did not have to think much about your health. Your parents, teachers, and other caring adults looked out for your health. They made sure that you ate the right food, had regular medical checkup and immunizations, and other health practices. As an adolescent, your personal health now becomes your responsibility. Every day you make health decisions so it is very important that you know correct health information. It is therefore, your responsibility to use health information wisely to guide your day- to-day activities. Live a healthy and happy life. This must start early in life. Your health habits and practices today as well as in the past, will greatly affect the status of your future health. Nowadays, health focuses on wellness. It is a positive approach that includes all the dimensions of health: physical, mental, emotional, social and moral-spiritual. Health is the well-being of your body, mind, and your relationship with others. On the other hand, wellness means striving to live your life to achieve your fullest potential, making decisions, and acting in healthy ways. It is practicing positive health behaviors based on sound knowledge and healthy attitudes. You are likely to have a high degree of wellness if you have a balanced life. Being healthy means having a balance of the dimensions of health. This results in attaining holistic health. Physical health means how well your body functions. It means you can carry out everyday tasks without becoming too tired. It also means you have enough energy to enjoy activities and to meet emergencies. It means developing healthful habits and avoiding destructive habits, such as smoking, drinking alcoholic beverages and taking dangerous drugs and harmful substances. You can attain this by giving your body total care, which includes the following:
  • 7.  Keeping your body fit by exercising and participating in active games Teenagers engage in physical activities to become fit  eating a well-balanced diet  getting adequate sleep and rest
  • 8.  drinking enough water  practicing cleanliness and good grooming habits  getting regular medical and dental check-up and treatment  avoiding harmful substances, such as tobacco, alcohol and drugs of abuse
  • 9. Mental or intellectual health means being a lifelong learner by continuously wanting to learn new things and improve one’s kills. A mentally healthy person is open to new ideas and experiences that can improve personal, family, and community life. Teenager learning new skills to improve personal and family life Emotional health involves understanding and liking yourself as well as accepting and learning from your mistakes. It refers to how well you meet the demands of daily life and how you adjust to new situations. It also means expressing your happiness, love, joy and hope as well as your sadness, anger, stress and fear in healthful productive ways. You can best practice these when you:  face life’s problems squarely  handle stress and seek help, if needed  express your emotions in positive ways  deal with life’s pressures and stresses in positive ways  build strong communication network among family, friends and peers Teenage students seeking advice from their teacher
  • 10. Social health refers to how well you get along with other people, how you react to social situations and how you interact with various social institutions. This can be observed when you--  make and keep friends  play/work well with a group  give and get help from others when needed  communicate well and show respect and care for yourself and others Teenagers sharing ideas and their talents with peers Moral-spiritual health means being at peace and in harmony with yourself, others and a higher power or bigger reality. What you feel, think and say what you believe in or value are shown in how you act. It refers to your personal beliefs, values, and faith. Places of worship There will be times when you will make decisions that deal with issues of right and wrong. Sometimes it will be difficult to decide because what is right or wrong is not clearly defined. But as you grow and become more mature, you will gain knowledge and experiences that will give you new insights and ways of looking at things or situations. In deciding what action to take, you can base your decisions on a set of values or moral principles. For example, telling the truth and showing respect are commonly accepted standards of right behaviour.
  • 11. Seeking guidance from parents, teachers, religious leaders, and other responsible adults will help you in making difficult choices. It is a sign of good character if you act according to a set of high ethical principles. You will gain respect and trust from others if you demonstrate good character. Moral- spiritual health, together with the other dimensions, will help you attain holistic health. Respecting parents or grandparents Take Actions for Your Health Directions: What health dimension(s) will be enhanced if you do the activities below? Write the number of each activity on the appropriate circle. Be able to explain your answer orally. 1. Read books. 2. Tell the truth. 3. Surf the internet. 4. Play different sports. 5. Go dancing with friends. 6. Attend social gatherings. 7. Respect the right of others. 8. Show your feelings in a positive way. 9. Say sorry when you have done wrong. 10. Consulting parents about your problems.
  • 12. Let’s see how these health dimensions are interrelated with each other Interrelatedness of Health Dimensions physical mental socialemotional spiritual Holistic Health spiritual emotional social mental physical
  • 13. The five dimensions of holistic health are interrelated. An individual is affected physically if food and shelter are not fully satisfied. This person will also be affected emotionally as she/he may feel inadequate, insecure, and unsafe. And how will this affect the mental health of the person? Anxiety may develop when a person is worrying about his/her condition. Relationship with family, friends, and with others may suffer also when a person is not contented and his/her longing for love and affection is not met. When the physical, mental, emotional, and social needs are not satisfied, a person may resort to unethical behaviour to satisfy his/her basic needs. It is very clear that each dimension affects the other. The dimensions are equally important to attain wellness or good health. These are like puzzle pieces that need to be fitted together for meaningful health dimensions interrelationship. We all seek a harmonious balance of all health dimensions to lead a happy and fulfilled life. It may sound difficult to attain but developing each dimension at this stage in your life will benefit you for a lifetime. Connect It! Directions: Write one health dimension in each circle. On the lines write activities you can do in each dimension that can contribute to holistic health. Add more lines if needed to write your answer. Write these on the lines. On the space provided below, explain briefly how the health dimensions are interrelated. Prepare to discuss your answer in class. Holistic Health __________ __________ ____________________ __________

Enrichment Activity To enrich your understanding about health dimensions, read /download/visit this website. http://www.buzzel.com/articles/5dimensions of health.html LESSON 2: CHANGES IN ADOLESCENTS Lesson Targets: Recognize that changes in different health dimensions are normal during puberty • Describe changes in different aspects of growth that happen to boys and girls during puberty • Explain that the patterns of change during puberty for each adolescent are similar, but the pace of growth and development is unique for each adolescent.
  • 17. Teenagers in Action Something to Ponder On You may be experiencing significant changes in yourself because you are now in another stage of life—adolescence! This occurs between puberty and adulthood. Puberty is the time when you start to become sexually mature. It usually happens at the age of 10 or 11 for girls and 12 or 13 for boys. However, this is not true for everybody. Some adolescents experience puberty either ahead or later than others. Some have their growth spurt earlier and some later. Still others may experience having pimples while others may not. The age when you experience puberty is influenced by heredity, nutrition, exercise, and other environmental factors. You undergo significant changes in the health dimensions -- physical, mental, emotional, social and moral-spiritual. All adolescents undergo similar changes as they grow and develop. However, there are differences in the way these changes happen to an adolescent; hence, change is similar and at the same time unique for each adolescent. The changes that happen during puberty are normal to adolescents. You have to know and understand these changes so that they will not surprise nor scare you. They are a normal part of your growth and development as a person. What is important is for you to learn how to cope with them in appropriate ways. You will learn that your wonderful body has built-in mechanisms that help you grow and develop as an individual. You just have to recognize and use them well. Check Your Life Skills Directions: Write YES if you practice the following health and life skill and NO if you don’t 1. I take care of my body. 2. I take pride in being unique. 3. I show respect for all people. 4. I try to make informed decisions. 5. I settle conflicts in healthful ways.
  • 18. 6. I work on having healthy relationships. 7. I seek new learning about growth and development. 8. I seek advice if I feel nervous about my body changes. 9. I accept how my body changes as I grow and develop. 10. I choose habits that promote healthful growth and development. As you study this lesson, try to think of how you can develop these health and life skills. If you are already practicing some, plan how you can continue to enhance them. Remember, these health and life skills will help you face challenges that you will meet today and in the future. What Makes You Grow? Your body grows rapidly during your growth spurt. Your growth during childhood and the changes during puberty are controlled by your endocrine system. This system is made up of a set of organs called endocrine glands. Your endocrine glands direct your growth. Endocrine glands produce hormones, which are released into the bloodstream and travel to other organs and tissues where they stimulate growth and regulate activity. Some hormones cause your body to grow and some cause other changes of growth. Your pituitary gland affects your growth more than any other gland. This gland produces many kinds of hormones and one of these is the growth hormone. This hormone regulates the development of long bones and muscles in the body. It causes growth throughout childhood and adolescence and helps your body reach its adult size or height. Remember, when your pituitary gland starts making growth hormones, your growth spurt begins. When it stops making much growth hormone, then your growth stops. When that happens, you have reached your adult size or height.
  • 19. Your pituitary gland also releases hormones that cause your reproductive glands to become active. Important changes occur inside and outside your body as your reproductive organs become more active. The testes produce the male sex hormone testosterone while the ovaries produce the female sex hormone estrogen. These hormones stimulate the many physical changes that adolescents go through during puberty. These include secondary sex characteristics such as development of the breast, appearance of maxillary and pubic hair, and others. Boys’ testes also begin to produce sperm cells. Girls’ ovaries begin to develop egg cells. Physical Changes These are some of the general changes that happen to adolescent boys and girls during puberty: • There is a rapid increase in height and weight. Boys experience this usually two years later than girls. The head, hands and feet grow faster first, then the arms and legs, and then the chest and shoulders. This is why the body of an adolescent seems to be out of proportion. • There are changes in body composition. Muscles develop rapidly, although boys’ muscles grow faster than girls’. Body fat increases, although the increase in girls’ body fat is more than the boys’. • Other changes: o There is a sudden increase in hormone production. o Bones become harder. o Sweat and oil glands become more active. Primary sex characteristics are changes directly related to sexual reproduction. The reproductive organs of both boys and girls grow and develop. The boys experience their first release of seminal fluid or ejaculation from the male genital.
  • 20. The girls experience menarche or the first release of blood and fluids from the female genital. Secondary sex characteristics are changes not directly related to sexual reproduction. Boys • The voice becomes deeper. • The Adam’s apple becomes bigger. • The shoulders become wider than the hips. • Hair grows on the face, body and pubic area. • The skin on the upper arms and thighs becomes rough. Girls • Breasts develop. • The hips become wider than the shoulders. • Hair grows on the underarm and pubic area. From Childhood to Adolescence Mental or Intellectual Changes
  • 21. Teenagers showing different talents/skills/interest as a sign of mental health Adolescents experience rapid mental development. Their mental abilities become sharper and more efficient.  Adolescents become more curious and inquisitive. They learn to question what others say. They try to get to the bottom of things—trying to find out what to believe in and what to doubt. • Adolescents make better decisions than children because they can evaluate risks and rewards better. They can sense the disadvantages and dangers as well as the advantages and rewards that might happen because of their actions. They can already think well before acting as well as know the importance of planning ahead. These characteristics help adolescents make better decisions. However, adolescents take more risks than adults because they enjoy the rewards that result from their actions. • On the other hand, adolescents have a tendency to become bored with routine activities; they need to be challenged. • Adolescents are already capable of thinking critically. This helps them understand issues and concerns about their development. • Adolescents also think less of themselves. This allows them to think and reason better. • Adolescents have the skills that let them control and coordinate their thoughts with their actions. • Adolescent students can focus their attention on what they want to listen to. They can also focus their attention on two or more things at the same time.
  • 22. • There is likewise an improvement in adolescents’ memory and speed in thinking. Their memory is more retentive and they can process information faster. Emotional Changes Adolescents in their moody state • Adolescents’ responsiveness to the call of their duties and responsibilities becomes greater. Stress tolerance becomes higher. • Adolescents are more emotional and this makes them open to being hurt or in danger. • Adolescent girls become self-conscious because of the changes that are happening to them. These also give them a feeling of insecurity.
  • 23. • Early maturing boys are usually taller and stronger; they have a good body image, so they are more confident, secure and independent Social Changes Teenagers with their peers doing different social activities • Adolescents are very self- conscious. They consider approval of friends and other adolescents or peers as very important. • Adolescents enjoy being with friends, so they stay longer with them after school. They enjoy choosing clothes to wear; they also crave privacy. These sometimes cause conflicts between adolescents and their parents. • Young adolescents choose friends who share the same interest with them. • Adolescents who grow up with family members showing love, guidance and support for each other are less likely to get involved with bad company and engage in fights, vandalism, smoking , drinking, or drug sessions. Moral-spiritual Changes Adolescents begin analyzing themselves during this stage. They try to find out who they really are and analyze their strengths and weaknesses. As a result, they understand themselves better and learn to accept and like themselves, including their weaknesses. They learn that house rules imposed by their parents are there to promote order and harmony at home. However, they are not absolute and some are negotiable as they mature. They begin to distinguish between rules that are
  • 24. negotiable and those that are non-negotiable. Non-negotiable rules, like smoking, are imposed because they are for their own good. During adolescence, boys and girls realize what they could become in the future. This helps them analyze what they are doing and how it could affect their future. They become more careful in making decisions. Paying respect to our elders is a good Filipino tradition We are Growing and Developing 1. Group by gender with 6-8 members in a group. 2. List down changes you have experienced or are experiencing – physically, mentally, socially, emotionally, and morally-spiritually. 3. Follow this format. Physical changes Mental changes Social changes Emotional changes Moral-spiritual changes
  • 25. Sum Up: Changes – Similarities and Differences Directions: Draw a Venn diagram like the one below and write in the outside area of the circle physical changes/characteristics unique among boys only while on another area those unique among girls only. Inside the overlapping area of the circle, write all characteristics/changes of adolescents that are shared by both. Enrichment Activity For additional information about significant changes during adolescence you can visit this website – http://pubs.exl.vt.edu/350/350-850/35 Adolescent Growth and Development. LESSON 3: DEALING WITH HEALTH CONCERNS Lesson Targets: 1. Identify health concerns during puberty 2. Analyze myths, fallacies, and beliefs related to adolescent health concerns 3. Apply self-management skills in dealing with some health concerns during puberty
  • 26. Something to Ponder On Health Concerns/Problems Related to Physical Changes Adolescence starts with puberty. It is the period of sexual development among adolescents. The secondary sex characteristics happen during puberty. Boys and girls experience rapid and uneven growth during adolescence. It is uneven because the outer parts of the body such as the head, hands, and feet grow first. They may feel awkward because the hands and feet may seem too big for the rest of the body. Remember, this development is normal and temporary so there is no need to be unhappy about it. Teenagers of the same age but with varying height and size  Postural Problems You will notice a great variation in the size and shape of adolescents of the same age. This variation can be a source of concern among teenagers who compare themselves with others. During the growth spurt, teenagers begin to grow at a rapid rate. Teenagers who grow taller than their classmates may feel conscious about their height. Some teenagers may begin to slouch because they are not used to their new height. Others may slouch on their chairs as they study. Some girls who develop their breast earlier may also feel conscious and tend to slouch. They may develop poor posture if they continue to do this. Remember, good posture helps maintain body alignment. It also helps the bones and muscles to continue to grow properly during adolescence.
  • 27. Other Concerns Related to Physical Changes Every individual goes through the changes of puberty at his/her own rate. Some may experience the changes sooner or later than the others. The growth pattern for girls is a little different from the growth pattern for boys. Girls are usually taller than boys around the age of 11 or 12. Then growth in height slows down for most girls while this speeds up for many adolescent boys. Within a few years, boys in general become taller than girls. This difference may cause uncomfortable feelings. Boys may also feel embarrassed when their voice “cracks” because of the growth of their larynx. This is part of growing up. Remember, every teenager experiences these changes. These are normal experiences and events in everybody’s life so there is no reason to worry and feel uncomfortable about it. Eventually, these awkward feelings will disappear as teens adjust to the changes in their growth and development.  Body odor During the early teen years, the sweat glands become more active. When teenagers play actively or engage in sports or other physical activities, they tend to perspire profusely. If they do not know how to manage this problem, it may cause unpleasant body odor. How does this happen? Sweat glands are numerous under the arms and any bacteria under the arms may act on perspiration and cause an unpleasant body odor. If you do not practice proper hygiene, then you might have body odor. Take a bath or shower daily. Soap and water will remove bacteria and excess oil on the skin. Apply deodorant or antiperspirant daily. Be sure to bring extra clothes and change when needed. These may prevent unpleasant body odor.  Dental problems The more common dental problems of teenagers include dental caries or tooth decay, halitosis or bad breath, and gingivitis or swelling of the gums. Both dental caries and gingivitis can lead to halitosis. It is important to remember that all of these are brought about by not brushing, poor tooth brushing skills and drinking carbonated drinks and eating sweets frequently. This can lead to proliferation of dental plaque, which is made up of colonies of microorganisms. Dental plaque hardens to “tartar” if not removed. So tooth brushing after every meal and flossing at least twice a day should take at least a minimum of three minutes to remove all food particles lodged between the teeth. Dental problems can also be prevented by doing the following:  Eating nutritious foods
  • 28.  Limiting between-meal snacks, especially sweet and sticky foods  Brushing and flossing to remove plaque or tartar  Visiting the dentist regularly, at least twice a year   Lack of sleep While sleeping, the body gets a chance to rest. Although most body activities slow down while sleeping, some remain active. The pituitary gland releases more hormones, like growth hormones, when one is asleep. Body cells grow and repair themselves more rapidly during sleep. Lack of sleep during the adolescent years interferes with these processes and might interfere also with proper growth and development. Teenagers need nine to ten hours sleep each night to feel well and rested. So you should refrain from staying late at night playing computer games, watching television or just staying awake doing something. Insufficient sleep has negative effects on your growth and development. Health Concerns Related to Social Changes At this point of your life, your friends become very important to you and you probably spend most of your time with them. You meet people and form new relationships.  Problems with relationships During adolescence, your relationship with other people changes. However, teenagers often change friends as they develop new interests. This may result in breaking up with old friends. As teenagers you must develop social and communication skills to have a healthy relationship with your family, friends, classmates and other important people in your lives. Effective communication involves exchanging ideas, feelings and viewpoints, and talking and listening skills. Let’s see how this skill applies some events/situations in your lives.  If you and another person disagree on something, listen to what s/he has to say and let her/him know your point of view. In this way effective communication will take place, thus preventing miscommunication.  If you are out with friends, let your parents know where you are. Let them know and ask permission if you have a change of plans, like staying late with friends or sleeping over in your friends’ house. This will show your parents that you are acting responsibly and safely. Communicating with them in that way will bring about good relationship. Health Concerns Related to Mental Changes
  • 29. As adolescents, you are expected to solve more complex problems than when you were children. Your thinking skills develop and you can see and understand other people’s point of view. Mental health concerns in adolescents may be caused by heredity, head injury or chemical imbalance. It may also be caused by stress from feelings of not being accepted, being poor or “different.” Abuse, death of a loved one, or separation anxiety can also be a mental health concern. Read more: Adolescent Mental Problems | eHow.com http://www.ehow.com/about_5081379_adolescent-mental- problems.html#ixzz1t3yf5Vx1 Emotional Changes Your emotions and feelings also go through changes during adolescence and you may experience these problems:  Mood swings/intense emotions You may be happy at one moment, then feel sad the next. This mood swing might be misunderstood by friends or family. Moodiness among girls may be due to changes in their estrogen level while among boys, it may be due to changes in their testosterone levels. These hormones can cause emotions to be very intense and swing rapidly. These emotional swings will settle down as you enter the next stage of your growth and development. This mood swing may be bothersome but you must accept that emotional changes during adolescence are a normal part of your growth and development. Knowledge about what is happening in your body during adolescence will help you understand better the changes you are experiencing. There are positive ways of dealing with intense emotions and of using extra energy during adolescent years. Get involved in worthwhile physical and social activities, such as sports, dancing and arts and crafts. These will help you feel better and worry less about the changes taking place in you. Problems related to sexual changes Adolescent boys experience “wet dreams” or nocturnal emission. This is involuntary ejaculation of semen during sleep. Although this is quite embarrassing, this is common among teenage boys during puberty. This experience may cause stress among teenagers so correct information about sexual changes will prepare them to accept this change positively. Adolescent girls experience the onset of menstruation. Girls having their menstrual period need to be more conscious about hygiene. The old belief that it is bad to take a bath or wash the hair when a woman is menstruating has no scientific
  • 30. basis. There is absolutely no reason why you should not wash your hair, or take a bath or shower during menstruation. In fact, a nice warm bath can do a lot to relieve menstrual cramps and premenstrual tension. You might want to avoid cold water during your period since it could, theoretically, cause uterine contractions that could increase menstrual cramps. If you experience puberty at an early age, don’t feel embarrassed to talk about it. Talking to your parents, responsible adults, doctor, or teacher is the best thing to do. Talking to a responsible adult will help teenagers feel comfortable with changes they are experiencing. Our Health Concerns We will write our health concerns (one piece of paper for each health concern) and drop them in the proper box: Illustration 5 boxes on each box is written a health dimension: 1. Physical concern 2. Mental concern 3. Emotional concern 4. Social concern 5. Moral-spiritual concern We will group ourselves and each group will try to analyze the health concern, find out more about it by reading, researching, interviewing, and other means. We will report our findings in class at the next meeting.
  • 31. GROUP REPORT RUBRIC Items Commendable Acceptable Poor Information Accurate More than 5 different sources Complete: description, managemen t, coping Well-organized Accurate 3-5 sources Some items missing Somewhat organized Some inaccuracies 1-2 sources Some information given Disorganized Visual aid Clear and helpful Messy and inaccurate None or inaccurate Presentation Cooperative Minor problems of cooperating Some arguments during the presentation; members did not take the presentation seriously Health concerns/problems brought about by changes during adolescence should be dealt with properly to prevent negative consequences. Since many of these can be prevented, you should learn coping skills/self- management skills to face these challenges positively. Coping skills – this will help you deal with sad, difficult and stressful situations /experiences in your lives. If you have developed coping skills, you can prevent serious problems resulting from these experiences. There are several coping techniques you can use in ordinary life situations. Some are very useful; some are not. Some can help you for a short time only but some can help you for a long time. Study the following coping techniques and see how you can practice them: Support- Seeking Strategies: 1. Talk to a friend who can do something about it. 2. Seek advice from responsible family members/relatives. 3. Talk to someone to find out more about the problem. 4. Look for someone who will sympathize with you. 5. Seek professional help. Positive Problem- Solving Strategies: 1. Do not act hastily. 2. Make a plan of action. 3. Look at the problem as a challenge. 4. Be creative in solving the problem. 5. Come up with different solutions to the problem.
  • 32. Avoidance Strategies (These are acceptable for a short-term, so do not exclude other ways of coping.): 1. Avoid being with people. 2. Prepare for the worse that may happen. 3. Wish the situation to go away or to be over. 4. Try to forget the whole thing. 5. Exercise or eat. 6. Hope a miracle would happen. Positive- reframing Strategies: Self- talk is a way to help you change your thoughts. Here are some self- talk statements that you can use as coping skill. These statements are useful when you are under stress or facing a challenge/problem: A. When you are preparing for a stressful situation, you can use any of these statements:  I know I can do it.  It’s easier once I get started.  What exactly do I have to do?  Tomorrow, I will be through it.  I have succeeded with this before.  I won’t entertain negative thoughts. B. When you are facing the challenge/problem:  I can do this.  I can only do my best.  I can ask somebody for help.  If I get nervous, I’ll take a deep breath.  If I feel tense, I’ll do my coping exercise.  It’s OK to make mistakes; no one is perfect.  I won’t rush. I will take it slowly step by step. C. When you are coping with fear:  I’ll survive this.  Relax! It will end.  Take a deep breath.  Lord/Allah, help me!  I can always call someone. D. Self- Congratulations:  I did it!  I did it well.  Next time, I won’t have to worry much.  I’ve got to tell this to_____________
  • 33. E. Affirmation:  I enter the day with a peaceful thought.  Every day in every way I grow stronger and stronger. Which of these coping skills do you tend to use? Which do you plan to use more? Are you someone who seeks the help of others or are you a positive problem solver? Don’t avoid or deny your feelings too much; it’s not healthy. Self -Talk Bubble  Identify a teen problem that you are worried about.  Write a positive statement about the identified problems. For example, if the problem is having too many pimples, you can say to yourself, “I can overcome this problem.”  Write a self- talk, just like a bubble dialogue.  You can use some of the statements you have learned in coping skills.  You can make your own design of self-talk scenario in your notebook/journal log. An example is shown below. You can cope with the changes that caused some of your health concerns at this stage if you will always make a responsible decision. There are lots of responsibilities and challenges ahead of you as an adolescent. You must handle those responsibilities and challenges successfully. Using coping skills will help you handle these challenges. “I can overcome this problem.” “I can ask somebody for help.”

Write ways to cope with the concern on lines provided for. Add or delete lines as needed. LESSON 4: HEALTH APPRAISED AND..... AMAZED Targets: 1. Explain the importance of health appraisal procedures during adolescence in order to achieve holistic health 2. Avail of health services in the school and community to appraise one’s health Something to Ponder On Health Appraisal and Screening Procedures When you were a child, your parents, older siblings, relatives, and other concerned adults made sure you ate the right food and had regular medical checkups, immunizations, and other health care. Now that you are already an adolescent, your personal health becomes your responsibility also. One way to do this is to know your health status so that you can take the necessary actions to improve your health habits and practices. In case there is a sign of a medical problem, early detection can help to prevent this from becoming serious that would need appropriate treatment. Monitoring health status can be done through regular health checkups and screening tests appropriate for you. It is very important to know your health status. For school age children and adolescents, the school health personnel, such as the school physician, school nurse, school dentist, as well as teachers and other school personnel perform checkups and screening tests at the beginning and towards the end of the school year. This is part of the school health service provided for students. Screening for blood pressure is added to the routine tests for height, weight, vision, and hearing. Immunizations are also updated. Adolescents who are experiencing growth spurts may also be screened for possible scoliosis. Scoliosis is the abnormal curvature of the spine, which causes pain and affects growth. Additional tests may be recommended by your physician or health care provider as needed. Managing my health issues/concerns as teenager
  • 35. Evaluation of the results of checkups and screening tests is done by the school health personnel. Students who may need health counselling, referral, and follow up will be identified and guided for proper action. As an adolescent, you should always remember that you are also responsible for your own health. Monitor your body for changes that may need medical checkup. This is often referred to as part of self- care. For girls, it is recommended to check your breasts for possible masses or lumps the moment you start menstruating. You should do this monthly, specifically one week after the onset of menstruation. You can do this while taking a shower or facing the mirror. This breast self-examination (BSE) can help females check any abnormalities that might need medical help. Remember, there are normal changes during and right before menstruation so it is better to perform BSE after menstruation. Develop the habit of doing BSE monthly. Scoliosis Screening Scoliosis is a condition in which the spine curves to the side. It is an abnormal lateral or side-to-side curvature of the spine. This condition commonly develops during growth spurt of adolescents. It affects girls more often. This condition can be corrected if treated early before the bones have fully developed. The following signs should be referred to a doctor for treatment.  One of the shoulder blades is more prominent.  The head is not aligned to the center of the pelvis.  A hip appears higher or is more prominent than the other.  The rib cage is uneven.  The waist is uneven.  The entire body is leaning to one side. In the school, your school nurse or your health teacher can do the scoliosis screening test. During the test, the school nurse will observe your posture for signs of scoliosis. Early detection can prevent scoliosis from progressing. Screening Procedure Forward Bend Test: 1. Stand facing away from the screener. 2. Bend forward at the waist 90 degrees, feet 10 cm apart, knees straight, and feet parallel to each other. 3. Palms of the hands are facing each other and arms hang down, and are relaxed. The head is down.
  • 36. It is normal if the screener observes the following:  Both sides of upper and lower back are symmetrical.  Hips level and symmetrical. There is possible scoliosis if the screener observes the following:  One side of rib cage and/or the lower back showing uneven symmetry.  Curve in the alignment of the spine. It is very important that you are aware of any change in your body. Any deviation from the normal must be reported to your parents so that you can seek medical advice. You can go to your school clinic to seek advice from the health personnel there. Your teachers can also help you. Don’t wait for your health problem to get worse. You have to act now. Organize What You Know The graphic organizer below shows the importance of health appraisal/screening test in attaining holistic health. Draw an arrow connecting the screening test to its importance. Remember that the school health personnel, so with your barangay health personnel, are there to help maintain the health of the students/people in the school or community. Avail of any health service they offer. Holistic health can be achieved by practicing good health habits and submitting to screening tests. Screening tests Dental exam Height taking Weight taking Vision test Scoliosis test Medical exam Breast-Self examination Keeps you informed about your general health status. Keeps you informed of any dental problems Gives you an idea about your growth rate Keeps you aware if you are within your ideal weight Keeps you informed of your visual acuity Keeps you informed of any abnormal curvature of your spine Checks unusual lumps
  • 37. Activity 2: My Health Screening Contract Now, do you realize the importance of submitting to a screening test? A Health Screening Contract will remind you to go for screening. Here is an example of a Health Contract.

It provides you with the needed calories and nutrients for your maximum energy and wellness. Calories or kilocalories are units of heat that measure the energy used by the body and the energy that foods supply to the body. You need energy to fuel everything you do-- from playing, making assignments, talking to your friends, watching television, sleeping, and all your activities. Nutrients, on the other hand, are substances in food that your body needs to grow, repair itself, and to supply you with energy. If you choose the right foods to eat, these will provide your body with the nutrients it needs to help you look and perform at your best. Nutritional needs vary for each stage of life, so it is important to eat a healthy diet through all life stages. Adolescence is one of the fastest growth periods in a person’s life. The physical changes during this stage affect the body’s nutritional needs. Changes in your lifestyle as an adolescent may also affect your food choices and eating habits. With your active social life and busy schedules, you might often skip meals and just take snacks throughout the day. You might also often skip breakfast, not knowing that this important meal will give you the energy to make it through the day and to perform well in school. When you skip meals, you might resort to eating snacks in fast foods or “carinderias,” or not eating at all. When you eat outside, your choice of foods are often high in fats and sugar that provide less nutritional value. These practices are unhealthful and are major risk factors in
  • 46. developing chronic diseases, such as heart diseases, diabetes and even some types of cancer. To achieve your full growth potential, proper food selection and eating are very essential. You must know your physical need for food and follow the dietary guidelines appropriate for your age. You sometimes won’t eat a dish --- even if you know it is healthful because you don’t like its taste. Most often the desire for food or is stronger than the need to eat. Always remember that you need to eat foods that your body needs to support your growing body and to prevent future health problems. Following certain guidelines will help you choose a balanced and healthful diet.  Eat a variety of foods every day. Choosing and eating a variety of foods each day is important in building a healthy body.  Consume fish, lean meat, poultry or dried beans. Eating these will give you protein, vitamin B, iron and zinc. These foods may contain high levels of fats but choosing lean meat and poultry without skin and limiting the egg yolks, nuts, and seeds can help limit fat intake.  Eat more vegetables, fruits, and root crops. Vegetables and fruits are rich in vitamins and minerals and some are high in fiber. Eating a variety of food from this group will help you prevent chronic diseases and will keep you healthy.  Eat foods cooked in edible/cooking oil in your daily meals. Eating foods cooked in edible/cooking oil daily prevents chronic energy deficiency. Fats and oils are also essential for absorption and utilization of fat-soluble vitamins, such as vitamin A. Olive oil is the best and healthiest oil and it's good for your health.  Consume milk, milk products and other calcium-rich foods, such as small fish and dark leafy vegetables. These are good sources of protein and calcium.  Use iodized salt, but avoid excessive intake of salty foods. Consuming less salt can reduce your chance of developing high blood pressure or can decrease your risk of cardiovascular disease.  Eat clean and safe food. It is important to handle and prepare food safely by observing cleanliness. Wash hands and use clean utensils in preparing and cooking food.  For a healthy lifestyle and good nutrition, exercise regularly, do not smoke, and avoid drinking alcoholic beverages.
  • 47. Teenagers’ active life Now, knowing some facts about the importance of nutrition, think about these questions.  Do you eat the right food you need for good health?  Are you getting the nutrients you need from the food you choose for your meals?

As a group choose several words from the word search and link/connect/web them to make a definition/concept. 6. Use a definition map to describe and define the words you chose and their related ideas. Each map should include branches that answer questions about the vocabulary word such as, “What is it?”, “What is it like?”, or “What are some examples?” Here is how you can do a definition map. What is it? What is it like? What are some examples? Activity 2: Check Your Daily Food Diet Directions: List down all the foods and drinks you had for breakfast, snacks, lunch, and dinner yesterday. Indicate also where you ate your meal in the column for source. Study your list and check if you followed the nutritional guidelines for a balanced diet. Nutrition Calories Nutrients Rice Eggs Milk Energy CalciumIron Food Diet
  • 49. Meals Foods eaten Source: Eaten at home/fast food/others Breakfast Snacks Lunch Snacks Dinner Answer the following questions: 1. Did you eat meals regularly? 2. What did you discover about the food you ate? 3. Where do you usually eat your meals? 4. Were you able to follow most of the nutritional guidelines? 5. Which guidelines were you not able to follow? 6. What do you plan to do now? 7. Will it help? How? Since you are already responsible and can make decisions for your own food choices, make the best choice and decision for your health. There is a variety of food available. Select those that will provide the best nutrients you need for proper growth, development and health. This is important for your lifelong wellness. Poor meals due to poor selection of food, eating foods high in fats at fast food centers, eating processed foods, and eating hurried meals at home and school may lead to some health problems, if not corrected. Studies show also that most of an adolescent’s diet needs attention due to the following findings:  Protein consumption is higher than needed.  Carbohydrates, fruits, and vegetables intake is too high.
  • 50.  Fat intake is much too high.  Calcium intake is below what is recommended daily. You should follow the nutritional guidelines for a healthful diet. You should know how many servings from each food group daily are recommended. The Food Guide Pyramid will help you. The number of servings recommended for an individual depends on her/his age, size, sex, and the activity she/he engages in. For good health, all age groups must eat at least the lowest number of servings from each of the food groups every day. This is in order to meet the daily requirements of vitamins, minerals, protein, fibers, and carbohydrates. Activity 3: Check Your Nutrition Life Skills Directions: Write YES if you practice the life skill and NO, if you do not practice it. Be honest with your responses. Write your answer on the space before each life skill. I follow a balanced diet. I maintain a healthful weight. I eat a healthful diet. I eat the correct servings for the food groups in the Food Guide Pyramid. I follow nutritional guidelines to keep me healthy. How many did you check? If you have five checks, it means you are really following good nutrition habits. If you did not check some of the items, you need to review your habits and practices related to nutrition. Your health may suffer later if you continue to have poor food choices and poor eating habits. Nutritional Needs of Adolescents The growth spurt during adolescence creates increased demand for energy and nutrients. As an adolescent, your total nutrient needs are higher at this stage than at any other stage in your lifecycle. It only shows that nutrition and physical growth are essentially related; optimal nutrition is a requisite for achieving your full growth potential.
  • 51. Due to your rapid growth and development at his stage, you have a greater need for certain nutrients, such as calcium, iron, protein, and energy foods. For bone development, you need extra calcium. It is likewise needed for the regulation of vital body functions, such as blood clotting, heart muscle contraction and relaxation, transmission of nerve impulse, and activation of some enzymes. Eating a balanced diet helps in building bone mass that will lessen your chance of developing osteoporosis in later life. Remember, more than 90 percent of bone density develops by the time you reach 18 years old. Adolescents, ages 10-18 have calcium requirements of 1000 milligrams per day. You can get calcium from dairy products, leafy vegetables, canned fish with soft edible bones, and tofu. It is important to include any of these foods in your daily diet. Teenage boys and girls have high demands of iron due to growth spurt. The onset of menstruation among girls also increases the need for iron. Boys 13–15 years of age need 20 milligrams while girls need 21 milligrams daily. Do you know that iron from meat is better absorbed by the body than iron from plant sources? You can improve the absorption of iron from plants by eating fruits or drinking fruit juices that contain vitamin C. Iron is important for proper functioning of cells and for resistance to infection. Due to your accelerated growth and development, you need body-building food. Boys, ages 13-15, need 71 grams of protein daily while girls need 63 grams daily. Body-building food is protein-rich necessary for the growth and development of your body, specially your bones and muscles. Throughout your life your body replaces damaged or worn-out cells by making new ones. Protein-rich food helps the body repair itself. Protein also helps the body make enzymes, antibodies and hormones. Protein also supplies the body with energy even if it is not your body’s main energy source. Protein provides four calories per gram and excess protein in the body is converted to body fat. Animal products, such as meat, fish, poultry, eggs, milk, cheese, soybeans are good sources of complete protein. Remember, consume only the required amount of protein your body needs daily. An increase in the physical activities of adolescents requires more energy food. Energy-giving food or carbohydrates are the starches and sugars found primarily in bread, cereals, and in fruits and vegetables. In general, boys need more energy than girls due to the physical activities most of them engage in. Boys at the age of 13-14 need 2800 kilocalories for boys weighing 50 kilos while 2250 kilocalories are needed for girls weighing 49 kilos. .
  • 52. Your body uses energy from carbohydrates to perform every task you do. All carbohydrates are converted by your body to glucose, a simple sugar that is your body’s main source of energy. If your body does not consume glucose right away, it is stored in the liver and muscles as glycogen. When you need more energy, the glycogen is converted back to glucose. In cases when you take more carbohydrates than your body can consume, it is stored as body fats. Stored fats in the body may result to being overweight or being obese. Obesity must be avoided because this is a major risk factor to several chronic diseases, such as heart disease, diabetes, and some types of cancer. You need fiber or roughage, indigestible complex carbohydrates found in the tough parts of vegetables, fruits and whole grains. Fiber helps move waste through the digestive system. It prevents constipation and other intestinal problems, and reduces your risk of heart diseases. Some types of fiber help control diabetes by reducing blood glucose levels. To stay healthy, you have to eat 20-35 grams of fibers daily. Remember that there is a strong relationship between what you eat and your health, not only today but in the future as well. Proper nutrition also helps prevent diet-related chronic diseases in the future, such as cardiovascular disease, cancer, and osteoporosis. It is important for you to select a well-balanced diet always.
  • 53. Teenagers involved in active sports As active adolescents you need more energy food. A person doing high level activities requires more energy. If you are very active, you need to eat a variety of food. Eat only in amounts that your body needs or that matches your growth and activity level. You usually engage in physical activities like sports. During these activities wherein you perspire a lot, you lose some sodium. Usually the salt in your diet replaces the salt lost. Excessive perspiration during strenuous physical activities removes the potassium, sodium, and calcium from your body. You can replace these by eating foods, such as vegetables, cereals, meat, dried fruits, and milk. Exercise can also increase your body’s need for thiamine, riboflavin, and niacin. You need these vitamins for the release and use of energy when you are exercising or doing activities. You can get these from foods, such as meat, fish, beans, milk, cheese, poultry and eggs. Teenagers or athletes who engage in vigorous physical activities should take into consideration certain dietary precautions to ensure good health.  Drink enough water. Drink an extra 568 ml of water 2 hours before the activity and 85.2 - 170.4 ml every 10-20 minutes during the actual
  • 54. vigorous activity. Avoid drinks with high sugar content to avoid delay in stomach emptying.  Eat foods rich in iron. Athletes should also eat citrus fruits. Citrus fruits help facilitate body’s absorption of the iron in cereals, vegetables, and other non- meat sources. These foods help prevent potential iron- deficiency anemia.  Eat foods rich in calcium. Female athletes, for example, can be prone to osteoporosis (weakening of the bones as a result of loss of calcium). They must be particularly careful to eat foods rich in calcium to get the recommended dietary allowance of calcium. Your daily diet should be selected carefully. The nutritional guidelines for adolescents will make it easy for you to choose a balanced diet. You need different nutrients to be sure that your body functions properly. You also need body-building foods due to your accelerated growth and development. Your active life also requires more energy foods. Activity 4: Can You Help? Directions: Read the situation below and answer the questions that follow. Like all teenagers, Jose is an active teenager. He is a member of the school varsity team. He is about to compete for championship in the division level. His team practices daily. . During practice, he perspires heavily and needs to drink water very often. After his morning practice, he usually feels hungry during lunch time. 1. Suggest a menu for his lunch that will give Jose the nutrients he needs as an active teenager. 2. Suggest foods to replace the potassium, sodium, and calcium lost due to too much sweating. You can influence others to develop a healthy eating habit through different strategies. Help promote healthier eating among your family members, friends, and schoolmates through your advocacy materials.
  • 55. Assignment: Activity 5: Let’s Advocate Healthy Eating! Directions: Prepare an advocacy material like a poster/slogan/poem/song/rap to send a message about eating the required amount of vegetables, fruits and milk daily. Create a group for the presentation of your advocacy materials to the class or have an exhibit of all your output. Your presentation will be assessed based on the following criteria:  Clarity of the message  Correctness of information  Message impact Sum Up Complete the following unfinished statements: 1. I discovered that my eating habit is ___________________________. 2. I am aware that ___________________________________________. 3. As an adolescent, I need to eat _______________________________. 4. I will encourage my family and friends to eat___________________. 5. From now on I will ________________________________________.
  • 56. Enrichment Activity Directions: Read more about nutritional guidelines for adolescents in a Health or nutrition book recently published. You can also visit the following websites: http://fnri.dost.gov.ph/index.ph Nutritional guidelines for Filipinos LESSON 2: THE FOOD GUIDE PYRAMID FOR A HEALTHY LIFE Teen Ages 7-12 Lesson Targets:  Follow the Food Guide Pyramid for adolescents  Discuss the importance of following the nutritional guidelines appropriate for Filipino adolescents Something to Ponder On The Food Guide Pyramid will guide you on how many servings from each food group is recommended daily. There are six food groups in the Food Guide Pyramid. The serving requirements of each individual depend on age, sex, size, and activity level. Each day, we need to eat at least the lowest serving from each of the food groups. This is to meet the daily requirements of vitamins, minerals, protein, fiber, and carbohydrates of an individual.
  • 57. We all need to eat a balanced diet every day. This includes servings of foods from different food groups in the Food Guide Pyramid. This guide suggests that we consume--  food from the fats, oil and sweet group sparingly.  at least 1 glass a day of food from the milk and milk products group.  2 and 1⁄2 servings daily of food from the meat, poultry, dry beans, eggs, and nuts group.  1 egg a day (for teenagers).  3 servings of food from the vegetable group daily (for teenagers).  3 servings of fruits daily.  the greatest number of servings, which is 6-8 servings, of bread, cereal, rice, root crops and noodles. For you to grow and develop to the fullest and to improve your nutritional status, it is important to follow healthy eating guidelines such as:  Eat a variety of foods daily.  Maintain a healthy weight.  Eat foods that are low in fat, saturated fat, and cholesterol.  To lower the risk of heart diseases, avoid too much cholesterol in your diet.  Consume milk, milk products and other calcium-rich foods, such as small fish & dark green leafy vegetables daily.  Eat plenty of vegetables, fruits, root crops, and grain products.  Use sugar in moderation. o Eating too much sweet foods contributes to tooth decay.  Eat clean and safe food, cook food in edible/cooking oil.  Use iodized salt but avoid excessive intake of salty foods. Too much salt in the diet may increase the risk of having high blood pressure.
  • 58. Remember, healthy eating will reduce your risk of suffering from fatal diseases, such as cancer, heart disease, stroke, and diabetes. Healthy eating is important for proper growth and development. It can also prevent health problems, such as obesity, dental caries, iron deficiency, and osteoporosis. Women are prone to osteoporosis, so teenage girls should eat enough foods rich in calcium. This will help build strong bones to protect them from osteoporosis later in life. Eating a wide variety of foods in moderation daily is a good practice. Following the Food Guide Pyramid and the Nutritional guidelines for Filipinos will make it easier for anyone to have a balanced, healthful diet daily. How Many Servings Do You Need as an Adolescent? A serving is the size of food after it is cooked. Do you know that three ounces of cooked meat is about the size of a deck of cards? The serving sizes below will guide you in measuring the amount of food and liquid you take daily.  1-1/2 cups (12 ounces) of liquid is the size of a soda-pop can.  1 cup (8 ounces) of food is the size of a large handful.  1/2 cup (4 ounces) of food is about half of a large handful.  1 ounce of cheese is about the size of a 1 inch cube.  2 tablespoons (Tbsp) is about 2 times the size of the tip of your thumb (from the last crease).  1 tablespoon (Tbsp) is about the size of the tip of your thumb (from the last crease).  1 teaspoon (tsp) is about the size of the tip of your little finger (from the last crease). Daily Servings for a Teen’s Diet The table below is a food guide for adolescents. Adolescents can achieve their energy and nutrient requirements by eating a variety of foods daily. This guide may be used to ensure variety in foods eaten.

  • 65. Something to Ponder On Current Nutritional Status of Filipino Adolescents The results of the 6th National Nutrition Survey for Filipino adolescents show the nutritional status of adolescents from ages 11-19. Let us analyze the results. Survey shows that: If you will analyze the result of this survey, there are more underweight adolescents ages 11-12 than those who are 13-19 years old. The 7th National Nutrition Survey results show the following:  The prevalence of underweight among pre-adolescence/adolescents, 11-19 years old had significantly increased by 1.0 percentage point between 2005 and 2008.  Overweight adolescents on the other hand had decreased significantly by 0.2 percentage point from 4.8 % in 2005 and 4.6% in 2008. What do you think are the reasons? The next activity will help you see the reasons.  among adolescents, 11-12 years old: o 49 in every 100 have normal weight for their height o 26 in every 100 are underweight o 4 in every 100 are overweight  among adolescents, 13-19 years old: o 68 in every 100 have normal weight for their height o 12 in every 100 are underweight o 3 in every 100 are overweight  more males 11-12 and 13-19 years are underweight than females  more 11-12-year old males are overweight than females while more females age 13-19 years are overweight than males of the same age  the prevalence of underweight adolescents increased between 1993 and 1998 but declined in 2003
  • 66. Activity 1: How Are My Eating Habits and Practices? Directions: Check your habits/practices related to eating. Check (/) those that only relate to your habits/practices and cross (x) those that don’t. 1 I prefer fast foods and street foods. 2. I eat anything for my meals/lunch. 3. I am not careful in the selection of foods I eat. 4. I don’t have enough money to buy nutritious meals. 5 I eat my meals hurriedly to catch up with my classes. 6. I skip breakfast and have poor meals due to lack of time to eat. 7. I’m afraid of eating certain foods because these might cause pimples. 8. I just buy food available in school canteens even if I do not like them. 9. I am afraid of eating too much so I often skip breakfast. 10. I am not fond of milk; I prefer softdrinks.  What can you say about the results of your answers to this activity?  Do they reveal something positive or negative about your eating habits and practices?  Ask some of your classmates if they have similar answers. Some of your answers are the reasons why some adolescents are not properly nourished. Do you know which ones? Based on the same survey, these are the reasons why adolescents are undernourished.  Poor eating practices/habits  Poor food choices and intakes often influenced by peers and the media  Becoming conscious of the kinds and amounts of food they eat (i.e. females tend to eat less because of fear of becoming fat)  School canteens and cafeterias serving less nutritious foods (i.e. chips, carbonated beverages and artificial fruit juices)  Not fond of drinking milk,which is a good source of nutrients  Low intake of iron and vitamin C-rich foods resulting in iron deficiency
  • 67. Here are some reminders for eating right:  Always consider the Food Guide Pyramid  Decide on the serving you need  Follow good eating habits  Make healthy food choices  Be careful about the fat stored in food  Drink enough water daily Sometimes you just eat anything available on the table, but sometimes you become too choosy. Do you realize the effects if you don’t eat food that your body needs? The next activity will help you evaluate your eating habits.

What foods do you avoid eating? 5. What foods do you like the most? 6. How many meals a day do you eat? 7. Do you eat when you are stressed? 8. Which meal do you skip most often? 9. How often in a day do you take snacks? 10. How often do you eat at fast foods/restaurants? Analyze your answers to these questions and plan how you can improve your eating habits. Addressing the Problem of Malnutrition At present, do we have a program to address the problems of malnutrition in the country? Do we have government programs/projects that can help resolve the problem?
  • 68. The Philippine Food Fortification Act of 2000 seeks to address the micronutrient deficiencies in the country. Republic Act 8976 mandates the fortification of rice, flour, refined sugar, and cooking oil. It urges manufacturers of processed food to fortify their products under the ‘Sangkap Pinoy program. Fortification of staple foods is one of the most cost-effective ways of addressing malnutrition. It will supplement the insufficient diet of the common people. Rice has been fortified with iron, zinc, and beta-carotene varieties. This bio-fortification gives us 50-80 percent more iron and zinc in the rice. A government agency providing feeding program in the school In the school, are you aware of a feeding program? This is undertaken by the Home Economics Department to feed students identified to be undernourished. Nutrition concepts are taught in Technology and Livelihood Education. Some agencies and non-government organizations (NGO) also help in addressing the malnutrition problem in the country:  The Department of Social Welfare and Development (DSWD) in coordination with the Department of Education is also conducting feeding programs for public schools in the country.  The Department of Science and Technology (DOST) also helps in government campaigns by disseminating nutrition information and technology to the public.  The Food and Nutrition Research Institute (FNRI) is also doing its share by featuring healthy and nutritious recipes for Filipino families to enjoy. These recipes advocate Filipinos to live a healthy lifestyle.
  • 69. Malnutrition should be attended to immediately. Do you know that if this will not be checked early among adolescents, it will lead to serious problems? Some of these problems are:  Slow growth and development  Poor school performance  Sluggishness and fatigue  Poor nutrition in adulthood  Delay in the onset of secondary sex characteristics The Case of Micronutrient Deficiencies Micronutrient deficiencies are diseases caused by deficiency of vitamins or minerals in the diet. The most common micronutrient deficiencies not only in our country but also in the whole world are Vitamin A deficiency, iron deficiency anaemia and iodine deficiency disorders. Vitamin A deficiency (VAD) primarily affects children but the effects last a lifetime. It causes night blindness and, and later on, permanent blindness (xerophthalmia). The child suffering from VAD does not reach optimum physical growth and is prone to infections, that contributes to the high rates of sickness and death among young children. VAD can be prevented by regular consumption of vitamin A-rich foods, such as animal products, and orange and yellow fruits and vegetables, dark green leafy vegetables, and palm oil. Anaemia and iron deficiency Anemia is a condition in which the red blood cell count or hemoglobin is less than normal. It affects mostly adolescent girls women of child-bearing age and pre-school children. Anemia results in retarded physical growth, low resistance to infections and slow development of learning abilities. In adults it causes fatigue and reduced work capacity and may cause reproductive impairment. Foods such as dark green leafy vegetables, legumes and red meat are rich in iron, as are iron-fortified food products. Iodine deficiency disorder (IDD) results from lack of iodine in the diet. Iodine is needed for the production of thyroid hormone. The body does not make iodine, so you should get iodine in your diet. Iodine rich foods are— Breads Iodized table salt Cheese Saltwater fish Cow’s milk Seaweed Eggs Shellfish
  • 70. Frozen yogurt Soy milk Ice cream Soy sauce Iodine deficiency can lead to enlargement of the thyroid or goiter, hypothyroidism and to mental retardation in infants and children whose mothers lacked iodine when they were pregnant. IDD is the most common cause of preventable mental retardation. In severe cases it can lead to deaf-mutism, cretinism and other serious disorders, as well as reproductive impairment, which results in miscarriage, stillbirth and birth defects. Activity 3: Internet Detectives 1. Group the class into three, with a group researching on a common micronutrient deficiency. 2. Have each group prepare a presentation about their assignment, including preparation of teaching aid for the class to better understand their presentation, and 3 questions to ask the class after the round-robin presentations. 3. On the day of the presentation, only three members of the group will present and the classroom will be divided into 3 areas, one per micronutrient deficiency. The groups will go through the different areas round-robin style and listen to the presentation of the group member assigned to the area. The group presenters will take turns presenting to enable them to go through all the areas also. 4. At the end of the presentation each group will take turns asking their questions. Activity 4: Reflect and Change!
  • 71. Directions: Listed below are nutritional habits. Reflect on your nutritional habits and check the appropriate column where you think your daily habits fall. Be honest in answering this activity. A- Always S- Sometimes N- never Nutritional Habits A S N I eat a variety of foods every day. I buy only nutritious snack food items. I always try to make time for a good meal. I eat together with my family during meals. I pack breakfast to be eaten when I reach school. I bring packed nutritious and safe foods when eating out. I eat nutritious foods at home and even outside our home. I know the negative consequences of fad diets to my health. I sleep early so that I will wake up early and have enough time to prepare for school and eat breakfast. I choose foods wisely, making good use of salads, fruits and vegetables and whole grains when eating out. Evaluate your answer.  How many A’s do you have?  How many S’s and N’s do you have?  How will you describe your nutritional habits?
  • 72. Teenagers need to eat nutritious meals Eating Disorders Adolescent girls tend to eat less because of their fear of becoming fat. They become choosy with the foods they eat, preferring snack foods to full meals. Some are too conscious about their weight and their efforts to lose weight get out of control. Due to their desire to lose weight, they develop eating disorders. They get carried away with losing weight and becoming thin. An eating disorder is an extreme, unsafe eating behavior that can cause serious illness or that may even result in death. The exact cause is unknown. Some may have serious underlying mental and emotional problems that need professional treatment. They develop eating disorders that if not treated earlier can lead to serious health problems. It might also lead to death. Teenagers who have eating disorders usually have a family history of weight problems, depression, or substance abuse. In this case they need professional help. Some common eating disorders are anorexia nervosa, bulimia, and binge eating disorder. Anorexia nervosa is an eating disorder characterized by self-imposed starvation leading to excessive weight loss. It is an extreme fear of becoming stout and a distorted view of their body size and shape. It is a psychological disorder with physical and emotional consequences. Those experiencing this eating disorder see themselves as fat even if they are not. Their fear of being overweight is too strong. Outside pressures, high expectations, the need to achieve or the need to be popular,
  • 73. and the need to be accepted are characteristics of people who tend to develop this disorder. If not treated earlier, those with anorexia nervosa become malnourished. The condition may also become severe enough to cause death. Some warning signs and symptoms of anorexia nervosa:  Dry skin  Fainting  Brittle hair  Dehydration  Loss of body fat  Irregular heartbeat  Loss of menstruation  Wasting away of muscle tissue Some behaviors that can also be observed from those with anorexia nervosa include the following:  They exercise excessively.  They wear bulky or loose clothing.  They make excuses during meal time .  They may shift the food around on their plate just to pretend they are eating. Bulimia is a disorder in which the clearing of digestive tract follows cycles of overeating. People with this disorder are too concerned with weight. They will eat large quantity of food in a short period of time. After eating, they will take laxatives to rid the body of the food to avoid gaining weight. They may induce vomiting, abuse laxatives or diuretics, and go on dieting, or do excessive exercises. These practices are harmful and will damage the body. The following are the effects of bulimia:  Damage the heart due to starvation  Damage the kidney due to laxative abuse  Vomiting and laxative abuse can lead to dehydration and serious malnutrition  Overeating can cause the stomach to enlarge and vomiting can cause the stomach to rapture  Damage the tooth enamel and injure the mouth and throat because of stomach acids coming out due to frequent vomiting Some warning signs and symptoms of bulimia nervosa:
  • 74.  Bulimic people have open sores in the mouth due to frequent vomiting.  Their throats are often red,  They have tooth decay due to constant exposure to acids in their vomit. Bulimia can be treated by undergoing psychological and nutritional counseling as well as intensive medical treatment. Anorexia and bulimia are common among adolescent girls and young women. There are also a few cases of boys suffering from this disorder. Anorexic and bulimic people have difficulty feeling good about their bodies no matter how good they may look. Seek medical help immediately if any of these disorders affect you. When bulimia is a problem, the following intervention will help you:  Avoid skipping meals.  Eat more high –fiber food.  Include fresh fruits and vegetables in your diet.  Drink 8-10 glasses of water and do 30-minute exercises daily.  Avoid finger foods and select meals that require eating at the table.  Eat regularly-timed meals consisting of a variety of foods in enough quantity. Binge eating disorder is characterized by compulsive eating. People who indulge in compulsive eating consume a large amount of food at one time but they do not eliminate it. Binge disorder may be an indicator that the person uses food to cope with depression or strong emotions. Binge eating is different from normal appetite increases or overeating during holidays. Those with a binge eating problem eat large amounts of food on a regular basis. They eat quickly or most often do something while eating, like playing computer games, watching TV, reading books, doing homework, and others. They don’t stop eating even if they are already full. This results in being overweight or even obese because of so many calories they have taken, which is more than what the body can use. Try the following strategies to stop binge eating:  Cope with stress. Find alternative ways to handle stress and other feelings without food. You can do exercises, meditation, or simple breathing exercises.  Take three regular meals and choose healthy snacks. Do not skip meals as this often leads to binge eating later in the day. Take your breakfast, then have a balanced lunch and dinner on scheduled mealtime. If you will take a snack in between, be sure to choose healthy snacks.  Stay away from temptation. Do not store junk food and other unhealthy snacks in your refrigerator or cabinet.
  • 75.  Stop dieting. Depriving yourself of food will just trigger food craving and you will have the urge to overeat. What you can do is to focus on eating nutritious foods in moderation. Avoid being uncomfortably full.  Avoid dullness/boredom. Try to do something worthwhile instead of snacking. You can read, do gardening, paint, bike, walk, and other hobbies.  Do some exercises. Exercise this will not only help you lose weight but will reduce stress as well. It gives a natural mood-boosting effect that will help you stop that emotional eating practice.  Have enough sleep. Instead of eating when you are tired, it is better to take a nap or sleep earlier to boost your energy.  Know your body. You must know when you are physically hungry. If you have just eaten and feel like eating again, just ignore it. It is just emotional hunger.  Note the food you eat. Recording the food you eat, the time, quantity, and the feeling while eating will help you see the pattern. Do you overeat when you feel stressed, upset, hurt or angry? You will see the connection between your mood and binge eating.  Get help. Build a solid support network such as with your family, friends, or join a support group. You can also seek medical help. Remember, you can avoid binge eating by developing a healthier relationship with food. It must be a relationship based on your nutritional needs and not on your emotional needs. You must eat for your health and nutrition. Having a balanced meal plan and choosing healthy foods can help you avoid binge eating. Watch your eating behavior. There are some behaviors that may indicate that you are at risk for developing an eating disorder. Do the next activity to check your eating behavior. Activity 5: Check Your Eating Behavior Directions: Check the number if the behavior relates to you and cross (x) if it doesn’t . 1. I eat secretly inside my room. 2. I feel out of control when eating.
  • 76. 3. I usually eat much food hurriedly. 4. When I see food I eat even if I am full. 5. I feel ashamed and disgusted after eating. 6. I hide and stock food to eat later in secret. 7. I feel relieved from stress or tension when eating. 8. I never feel satisfied, no matter how much I eat. 9. I eat normally with others but over-eat when alone. 10. I eat continuously throughout the day, with no planned mealtimes. Answer the following questions:  How many did you check?  If you have checked all or most of the items above, reflect on your eating behavior. You might need to change your eating practice. Health Problems Brought About by Obesity Due to Binge Eating If not treated, binge eating disorder usually leads to obesity. Several health problems may occur when you are obese, such as:  Stroke  Osteoarthritis  Type 2 diabetes  Heart disease  High cholesterol  Gallbladder problem  High blood pressure  Joint and muscle pain  Risk of having a certain type of cancer Remember, all eating disorders need immediate attention since these are serious health problem. Discuss the problem with a responsible adult who can help. Better yet, consult a health professional. Activity 6: My Eating Style
  • 77. Direction: Write YES if the eating style relates to you and NO if it doesn’t. 1. I eat only when I feel hungry. 2. I eat more when I feel depressed. 3. I eat more then I vomit after eating. 4. I eat more when I am bored. 5. I eat then take laxatives to rid my stomach of food. Answer the following questions after the activity.  How do you find your eating practice?  What do you plan to do with what you discovered about your eating practice?  Do you think you have healthful eating practices?

Show a typical Filipino male and female adolescent. Cover the whole shield with the picture so that the shield can be distinguishable In general, diseases can be either communicable or non-communicable. Communicable diseases are due to an infectious process and can be transmitted from one person to another. As such, prevention and control of communicable diseases is a public health concern. Communicable diseases, such as bronchopneumonia in children and tuberculosis are one of the major health issues in our country. Although there
  • 82. have been improvements in the prevention and control of these diseases in the last 10 – 20 years, it remains to be a concern. Its negative effect can be felt at home, in school, and in the community. Families with sick members face financial and emotional problems. In schools, absenteeism due to infections affect student learning. Community people become at risk when epidemics happen, interrupting work and other productive activities. In order to free ourselves from the emotional pain and financial problems brought by diseases, we need to protect ourselves through good personal and environmental health practices. Are you now ready to shield yourself against communicable diseases? Let’s get started! As a starting point, it’s a good idea to check what you already know about communicable diseases. This is a diagnostic exercise, so don’t worry if there are items which you can’t answer. Pre-test A. Find the Secret Message Direction: Complete each statement by writing the missing word.

Lesson 1: Health-- More Than Being Disease-Free Note to the Illustrator: Please localize the drawing. Show a typical Filipino family. Lesson Targets  Discuss the concept of health and disease  Accept personal responsibility for one’s health  Practice ways to attain holistic health Something to Ponder On In the first Module, you were introduced to the concept of holistic health. You learned that health has several dimensions that are interrelated. Before we discuss health and disease in detail, let us first build on what you know about these two concepts.
  • 87. To the Illustrator: Please enlarge the concept web and delete the black lines at the right side of the drawing. I’m sure you wrote interesting information about health and disease from your previous learning and experience. As you read and understand the content of this lesson, try to compare new concepts with your prior knowledge about health and disease. Health as a concept is continuously changing as people see it differently. In the past, it was regarded as simply a condition of being free from disease. Then, it became equated with proper hygiene. Today, we know that to be healthy is not only to be free from disease. As our most important resource, it also includes living a quality of life that maximizes our potential and develops our sense of well-being. Health is both a personal and social responsibility. It is the product of the collective decisions that we make about our lifestyle in general. The food that we eat, the number of hours of sleep we get, the time we allot for rest and recreation, the way we manage stress and the type of physical activities that we do, all impact our health and the health of people around us. On the other hand, disease is just one manifestation of ill-health. It is a pathological condition that disrupts the normal functioning of the body. Unlike illness, which is subjective because it is based on the patient’s experience, disease is objective, characterized by an abnormality in the structure or function of body organs. However, one can have a disease and not be ill. And one can be ill even without disease. Reflect, Write, and Share Think of everything you know about health and disease. Write down words or phrases that you associate with these two terms. Then discuss your answers with a partner. Health Disease
  • 88. This Module will focus on communicable diseases. In general, diseases can be classified as communicable or non-communicable. Communicable diseases are caused by pathogens or disease-causing organisms and can be transmitted from one person to another or from animals to people. Examples include common cold, influenza, cholera, dengue fever, tuberculosis and warts. When the body is invaded by a pathogen, the invasion is called an infection. On the other hand, non- communicable disease cannot be transmitted from one person to another. These are also known as lifestyle-related diseases because danger or risk factors include obesity, smoking, lack of physical activity and exercise, and high-cholesterol, high salt diet. Cardiovascular diseases, cancer, chronic lung diseases and diabetes are the most significant non-communicable diseases in our country because they are the leading causes of death among Filipinos. Before we go to the nature of communicable diseases, it is important to understand first the relationship between health and disease. Let us study the following diagram: http://www.emunix.emich.edu/~bogle/wellness%20continuum.jpg Note to the Illustrator: Copy the dimensions but change spiritual to moral-spiritual. Delete the word heartiness in the continuum. The diagram shows that holistic health encompasses emotional, environmental, moral-spiritual, physical, social, and mental dimensions.
  • 89. Health and disease can be seen as a continuum. As one goes up, optimum wellness is reached. On the other hand, a movement downward indicates progressive illness and premature death once the lowest point is reached. Since life consists of changing events and conditions, a person’s health fluctuates along the continuum. The idea is to always move towards health and wellness. Thus, even if one has a disease, one can move towards wellness. Assess your health at present. Where are you in the continuum? How do you improve your position to attain optimum wellness? Health is more than the absence of disease because being disease-free is only one aspect of physical health. The modern view considers health as the major tool or resource in attaining quality life. To be considered healthy, one needs to balance the various health dimensions. This can be done by consistently demonstrating health-promoting behaviors in each health dimension. Study the following pictures: Health is more than the absence of disease because being disease-free is only one characteristic of health. So, the modern view considers health as the major tool or resource in attaining quality life. In order to be considered healthy, one needs to strike a balance among the various health dimensions. This can be done by consistently demonstrating health-enhancing behaviors in each of the health dimension. Study the following pictures: The Components of Health Components of Holistic Health Were you able to identify the health dimension being shown in the pictures? Compare your interpretation with the following:  The picture on the upper left shows someone playing volleyball, an activity that can improve one’s’ physical health.
  • 90.  The picture on the lower left shows an Igorot woman flashing a bright smile. She exhibits good emotional health.  At the center are two pictures which show the interrelationship between moral-spiritual and environmental health. Our personal relationship with a Supreme Being and our harmonious relationship with nature are both key components in attaining holistic health  On the upper right, we can see a group of teenagers happily conversing. They are enhancing their social health.  The lower right picture shows women engaging in an activity to harness their mental health. These activities are just examples of the many things you can do to attain holistic health. The challenge for you is how to integrate healthy practices into your lifestyle and make them a habit. Value your health by taking good care of it. It will mean practicing discipline and consistency on your part, but it will be worth it. Now, let’s do an activity that will encourage you to live a healthy lifestyle. Sum Up Let’s sum up the key points in this lesson: H- ealth is more than the absence of disease. My Health Pledge I accept personal responsibility for my own health and I will show my commitment by practicing the following activities to attain holistic health: 1. ____________________________________________________ 2. ____________________________________________________ 3. ____________________________________________________ 4. ____________________________________________________ 5. ____________________________________________________ Signed: ______________ Date: _____________________________ Witnesses: ________________ __________________________
  • 91. E – nhancing behaviors should be consistently practiced to safeguard health. A- ttainment of good health is both a personal and social responsibility. L – ifestyle diseases are caused by unhealthful practices. T – ype of activities that we do affect our health. H- olistic health is the key to quality life. Lesson 2: Bad Air, Germs, or Combined Factors? Lesson Target  Analyze the major beliefs about the cause of disease Something to Ponder On In order to fully understand the nature of health, we need to understand the nature of disease. People in various times of history have been curious about the cause of disease. They tried to explain it as either a supernatural or a natural event. Supernatural Belief Germ Belief Agent-Host - Environment Belief Poisonous gas DISEASE Did you know that until the 1850s, people’s fear of disease was worsened by ignorance?
  • 92. The Causes of Disease Beliefs on the cause(s) of diseases have undergone changes through time. The Supernatural Belief During the ancient times, people thought that disease was brought about by sorcery, witchcraft, fate, or spirit aggression (God’s punishment or devil’s work). These supernatural beliefs explained that disease was caused by a supernatural being (a god or a dead ancestor), or a person with special powers (a witch or a sorcerer). The belief in the supernatural cause was evident during the “Black Death” or bubonic plague of the 14th century. The bubonic plague bacillus that came close to wiping out the global population was believed to be God’s punishment for people’s sins. The Poisonous Gas Belief Another major belief during the 1800s is the poisonous air belief of disease causation. According to this view, disease, such as malaria, was transmitted by poisonous gases from rotting plants or bad vapor that came from swamps (the word malaria comes from mala aria meaning “bad air”). The Germ Belief Before the turn of the 20th century, the germ belief about the cause of infectious disease became very popular... This belief holds that microscopic organisms are responsible for infectious diseases. Although revolutionary, this belief is quite limiting because it only considers a single cause of disease. The Agent-Host-Environment Belief Since many people believed that the one-cause idea of the germ belief was not enough to explain the actual cause of diseases, the Agent—Host--Environment belief was formed. It explains disease as a product of the complex interaction among three factors: agent, host, and environment. This is known as the classic agent—host—environment triangle. It helps us understand the nature of communicable diseases. It answers the “who?” (host), “what?” (agent) and “where?” (environment) of disease.
  • 93. The Classic Agent—Host--Environment Triangle The host is an organism, usually a person or an animal, affected by the disease; the environment is the condition outside the host that allows disease to be transmitted; and the agent is the organism that causes the disease. In the case of agents, although microorganisms have an important part in the disease process, we should remember that many of them are harmless and some may even be beneficial. There is now a growing awareness that the environment is not only a place for the host-agent interaction. Rather, it is an important factor in the disease process. In fact, to become an infection, the organism that causes the disease must be able to damage the host, has a susceptible host, and has a favorable environment. To prevent and control communicable diseases, we must be able to upset or cut the connection among the agent, the host, and the environment. So, understanding the agent--host-environment triangle is very important. K-Q-V Chart Complete the following chart based on the lesson and be prepared to share your answer with your seatmate. The first row has been done for you: Belief Key Point Question/s Value or Importance
  • 94. Why is the knowledge of the beliefs on the cause of diseases important? The Agent—Host—Environment triangle is one model that explains the cause of disease. Based on this belief, the connection among the agent, host, and environment must be cut in order to prevent disease. Among the four beliefs, which do you support? Do you have your own belief on the cause of disease? What is it? Write your personal opinion. This is My Belief _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ __ Supernatural Disease is caused by spirits, magic, or sorcery. Is there proof that supports this belief? How can this belief hinder people’s quest for scientific ways to explain the cause of disease? This belief can enhance one’s faith in a supernatural being and encourages a person to do good so as not to suffer from disease.
  • 95. I’ll Change It My Way Write your opinion on how you can change the agent, host, and environment to prevent disease. Agent Host Environment
  • 96. Sum Up The Cause of Disease Since the earliest times, people have asked why Communicable diseases caused people to die; Infecting people rich and poor Bringing pain, death, and misery at their door. In their desire to understand why they were sick They turned to gods, sorcery and magic; The supernatural belief gained popularity As people spoke of spirits and divinity. Then the poisonous gas belief was born That put blame to air pollution; It claimed that bad air caused infections Such as malaria, and other afflictions. When the world of microbes was made known People turned to the germ belief of disease causation; Thus people became busy with disinfection And other ways to bring germs to extinction. But others proposed that germ was not the only cause But also the environment and the host; These three factors interact to make us sick According to a belief known as “epidemiologic.” Lesson 3: Disease Factors-- Spreading Ill Health
  • 97. Lesson Targets  Discuss the factors in the development of disease  Formulate guidelines to lessen the impact of these factors Something to Ponder On Communicable diseases remain to be the leading causes of disease among Filipinos. There are several factors that facilitate their transmission. 1. Personal Factors Health is both a personal and social responsibility. Our unhealthful practices can predispose us and other people to communicable diseases. For example, not washing our hands properly after using the toilet can make us susceptible to parasitic infections. When we have colds and we don’t practice cough etiquette, we spread the germs to people around us. 2. Economic Factors Poverty is a big factor in disease transmission. It is a complex social problem that leads to a lot of other issues, such as overcrowding, limited access to education and health care, lack of safe water and food, inadequate excreta disposal facilities, and poor living conditions. Moreover, the culture of poverty creates a sense of hopelessness on the poor because they often become victims of discrimination in the utilization of healthcare services. Lack of accurate information about nutrition, hygiene, exercise and sleep may also lead to bad habits that weaken the body’s natural defenses against disease. 3. Cultural Factors Our culture is the sum of what we have learned and transmitted from one generation to another as a people. There are cultural beliefs that can provide us with a false sense of security thus delaying healthcare and appropriate treatment. Many Filipinos still consult quacks or fake doctors and fortune tellers to seek advice about their health. There are also superstitious beliefs in different parts of the country that can directly or indirectly impact our health. Let us mention some:  Taking a bath on a Friday will make one sick.
  • 98.  Washing the eyes with the first urine early in the morning is an effective cure for sore eyes.  An amulet or anting-anting protects the wearer from diseases and helps counteract witchery.  Relapse or binat is caused by eating certain kinds of food or by cutting the hair too soon after illness. This is best treated by fumigating the patient with smoke produced by burning the offending food or the patient's hair. Can you give other examples of superstitions related to diseases? 4. Environmental Factors Unsanitary conditions and the presence of toxic chemicals, hazardous pollutants and wastes in food and water have bad great effects on our immune systems. Extreme weather conditions due to global warming make people more vulnerable to lots of infections because they weaken the body’s defense mechanism. 5. Political Factors Political issues, such as corruption affect the provision of health care services and resources to the people. In many cases, people’s health is not given utmost priority. 6. Educational Factors Disease transmission can also be due to misinformation or lack of information, thus education is crucial in disease prevention and control.

  • 101. Lesson 4: The Chain of Infection Lesson Targets Explain the elements of the chain of infection and their interrelationship with one another. Something to Ponder On Just like the keychain that holds together different keys, the chain of infection links together in a sequential order the six steps the chain of infection. Sequence Challenge Arrange the elements of infection in their correct order from one to six. _____ Pathogen _____ Reservoir _____ Mode of exit _____ Mode of entry _____ Susceptible host _____ Mode of transmission Do you want to know if you got the sequence right? Then, read on... To the Illustrator: Please draw a similar diagram but put the following labels inside each circle: personal, political, educational, environmental, economic, and cultural. To the Illustrator: Make a version of the chain of infection like the one above.
  • 102. In order to break the cycle and prevent communicable diseases, it is important that we understand first the different elements of the chain of infection 1. Pathogen or Causative Agent This can be any of the following biological agents: virus, bacterium, rickettsia, fungus, protozoon, or parasitic worm. The pathogen is capable of invading the host and causing disease. Pathogen Description Specific Diseases Caused by the Pathogen Viruses  requires intracellular parasite (can’t survive outside the host’s cell)  on the borderline between living and nonliving matter  can have varied shapes: helical (like a coiled spring), icosahedrons (with 20 triangular sides) or a very complex shape  attacks all kinds of biological agents, even bacteria  consists of a bit of nucleic acid (RNA or DNA, but never both) within a protein coat  AIDS (Acquired Immune Deficiency Syndrome)  chickenpox  common cold  dengue fever  influenza  measles  poliomyelitis  rabies  warts
  • 103. Bacterium  single-celled  no true nucleus  can be aerobic (needs oxygen) or anaerobic (does not need oxygen)  can be spherical (coccus), rod- shaped (bacillus) or spiral (spirillum)  can be in pairs (diplo-), in clusters (staphylo-), or in chains (strepto-)  majority comprise the normal flora (live in the human body)  majority are good/friendly (probiotic)  can be opportunistic (friendly bacteria turn harmful when the immune system weakens)  causes disease by directly attacking tissues or releasing toxins  some can live in a dormant state as spores  anthrax  cholera  diphtheria  gonorrhea  leprosy  tetanus  tuberculosis
  • 104. Protozoa  parasitic or free-living (can survive outside the host)  has a variety of shapes and sizes  various types: amoeba, ciliates, flagellates, or sporozoans found most often in stagnant water or moist soil  malaria  amoebic dysentery Fungus  thrive on dead or decaying matter  multicellular (like molds) or unicellular (like yeasts)  spore-forming (this is the reason why it’s sometimes difficult to treat)  cause diseases of the skin, mucous membranes, and lungs  tinea or ringworm (jock itch, athlete’s foot) Parasitic Worm  largest among the pathogens  can either be flatworms or roundworms  examples of flatworms are tapeworms (can be transmitted by eating raw  ascariasis  elephantiasis  enterobiasis  schistosomiasis  taeniasis
  • 105. fish/pork/beef ) and flukes (example is Schistosoma japonicum/m ansoni that causes schistosomia sis  examples of roundworms are pinworms and hookworm To the Illustrator: Please draw the pathogen based on the sample picture provided. 2. Reservoir This is the place where the infectious agent lives and multiplies. This can be living (animal/human/plant) or non-living (air/water/food/utensil/equipment). The most important reservoir is the human body. To the Illustrator: Please draw a human body, a plant, an animal, eating utensils, and food. 3. Mode or Portal of Exit
  • 106. This is the route through which the infectious agent leaves the reservoir. The common mode of exit is a break in the skin, nose, mouth or anus (discharges from the respiratory and gastrointestinal tract), and special body openings such as the vagina, penis, urethra, ears, and eyes. There are also cases when the pathogen leaves through mechanical means, such as through a mosquito bite or needle prick. 4. Mode of Transmission This is the means by which the infectious agent is transmitted from the reservoir to a new host. There are two types of transmission: a) Direct transmission- through close physical contact or direct person- To-person contact Examples: touching with contaminated hands, skin-to-skin contact (shaking hands, kissing, etc.) b) Indirect transmission- through an intermediate item or carrier Examples: vector-borne transmission –carried by mosquitoes or other insects and Vehicle-borne transmission - through contaminated items (fomites), such as eating utensils, contaminated food/water (food borne/waterborne) or through inhalation of the pathogen that has been suspended in the air for an extended time (airborne). There are 3 F’s that are usually involved in vehicle-borne transmission: Food, Flies, and Fingers. 5. Mode or Portal of Entry This is the route through which the infectious agent enters the body of the new host. Examples are mouth, nose, skin and the urogenital organs. The mode of entry is usually the same as the mode of exit.
  • 107. 6. Susceptible Host This is a person who is vulnerable to disease due to a weak immunity or a prior infection. Children and the elderly are more prone to a lot of infections. Immunization is one way to strengthen one’s immunity to disease. Study the dengue fever chain of infection below: Dengue Fever’s Chain of Infection Read the situation and trace what happened in the chain of infection above. A child was taken to the hospital because of persistent fever, severe muscle pain, and vomiting. She has rashes all over her body, especially on the extremities. The doctor told her that she has dengue and that she got it from being bitten by a mosquito that carries the dengue virus. She was asked to protect her/himelf from mosquito bites so that she can no longer infect other people. Chain of Infection Challenge A child was advised to stay at home because of influenza. Make a chain of infection showing the elements that made the child sick. Remember  The chain of infection has six elements arranged in sequence: pathogen, reservoir, mode of exit, mode of transmission, mode of entry, and susceptible host  Cutting the chain at any point will help prevent and control disease transmission. Dengue Virus Infected Person Skin Vector- borne (mosquito Bite) Skin Any person without protection
  • 108. Lesson 5: Cut the Chain and Be Free Lesson Targets  Identify different ways of breaking the chain of infection and transmission of disease  recommend actions to prevent and control communicable disease  demonstrate self-monitoring skills to prevent communicable diseases Something to Ponder On Although germs pose threats to your health, the good news is that there are many things that that you can do to prevent and control diseases. For example, you can practice cough etiquette to prevent the spread of respiratory diseases. Cover your cough and sneeze but do not use your hands; use a piece of tissue or handkerchief instead. If none is available, cough into the crook of your elbows or sleeves. Using hands to cover a cough can easily spread germs because you use your hands in touching almost anything. In general, there are three types of preventive approaches: Figure 1. The Levels of Prevention 1. Primary Prevention us an early intervention that aims to protect the host from initial exposure to the disease. It prevents a disease before it happens. Primary prevention activities include proper nutrition, healthful practices, immunization, and environmental sanitation. 2. Secondary Prevention is a system for the early diagnosis and treatment of disease when it has just begun. It aims to slow down the progress of the disease or stops its spread. Tertiary Secondary Primary
  • 109. 3. Tertiary Prevention is an intervention done when the disease is already in the clinical stage in order to prevent complications and progression to an advanced stage that will necessitate excessive care. Do you still remember the chain of infection? We can prevent and control communicable diseases by cutting the chain in its various points. Study the following diagram: Figure 2. Ways to cut the chain of infection To the Illustrator: Modify the diagram:  Replace the phrase “staff and management working together” at the center with: Observe Personal Hygiene and Environmental Sanitation  Instead of microorganism, write Pathogen  Delete s in reservoirs (just reservoir) and DELETE staff health  Instead of exit point, write Mode of Exit. Add Cough Etiquette.  Instead of transmission route, write Mode of Transmission and DELETE airflow control; replace with Quarantine  Instead of place of entry, write Mode of Entry and DELETE aseptic procedure and catheter care. Replace with protective clothing  DELETE treatment of underlying conditions, mobilization, and recognition of high-risk patients. Replace with good nutrition, regular exercise, stress management, immunization.

  • 112. Let’s Monitor Our Health Self-monitoring skills are competencies that will help us assess when we are healthy or sick. It is important that we are familiar with the normal condition of our bodies so that we can detect at once when something is wrong. It is also important that we have information, such as our vaccination record, so that we can assess our risk factors so that we can plan what to do as early as possible. Do you think your practices help you avoid diseases? Answer the following personal inventory with a YES or NO based on your health practices. Be honest.

Lesson 6: Infection, Stage by Stage Lesson Targets Discuss the stages of an infection Something to Ponder On When was the last time you had a cold? I’m sure you still remember the uncomfortable feeling that accompanied it. Can you share your experience with a severe cold? The common cold is an infectious disease, Like other infectious or communicable diseases, it undergoes several stages--from the entry of the cold virus up to the time when the sick person recovers. Let’s study the following illustration:
  • 115. To the Illustrator: Draw a bell curve like the one above. Remove the phrases enclosed in parenthesis. Replace the term Prodromal with Early Symptoms, illness with clinical period, convalescence with recovery. 1. Incubation Stage This is the time from the entry of the germs to the appearance of the first sign or symptom. This can last from several hours to several months or even years. For example, measles has an incubation period of two weeks while HIV (Human Immunodeficiency Virus) can invade the body up to several years before the condition becomes full-blown AIDS (Acquired Immune Deficiency Syndrome). Incubation periods not only vary from disease to disease, but also from person to person. One who has a stronger immune system can lengthen the incubation period of a disease. 2. Early Symptoms Stage This is when the general signs and symptoms of the disease appear, such as fever, nasal discharge, and rashes. It is the early stage of the battle between the germs and our body defenses. During this time, the disease is highly contagious. Diagnosis is difficult at this stage. 3. Clinical Stage This is the height of the disease when the infection is very severe. During this period, one is obviously sick as characteristic signs and symptoms of the disease appear. 4. Recovery Stage During this stage, there is a gradual return to health as signs and symptoms begin to disappear. The body is now on its way to recovery. However, when the body is unable to recover, disability or death may result. There are times when people experience a relapse. A relapse happens when a sick person partially recovers but goes back to the clinical stage. Recovery takes much longer after a relapse because the body defenses are still weak from a previous infection. Let us remember that the progress of a disease can be slowed down or stopped at any point as a result of the strong response of the body’s natural defenses or through medical intervention; but the best thing is to prevent contracting the disease in the first place.
  • 116. Let Us Remember An infection goes through several stages: incubation, first symptoms, clinical, and recovery. Relapse happens when the sick person returns to the clinical period after partial recovery. My Personal Encounter with a Pathogen Think of a communicable disease that you had. Share with a partner your personal experience as you went through the different stages of the infection. After 5 minutes, switch roles. Your friend will now share her/his story. How was your experience similar to your partner’s? Although infectious diseases go through different stages, there are specific signs and symptoms for a particular disease. I’m sure you’re ready for another challenge. Q and A Portion: It’s Your Turn You are one of the contestants vying for the title “Healthy Idol” and you pick this question: “If you were to compare a communicable disease to an object or an event, what would it be?

  • 117. Lesson 8: Common Skin Diseases during Adolescence Lesson Targets:  Explain the nature of common skin diseases during adolescence  Practice ways to prevent and control common skin diseases during adolescence  Distinguish facts from myths about common skin diseases during adolescence Something to Ponder On Your skin is the largest, essential protective part, and the most exposed organ of your body. Your whole body is covered with it. Your skin provides you visible signs showing that there is an infection affecting your body. Diseases affecting the skin can be non-infectious, but there are also skin diseases that are infectious and are usually hard to control. When an infectious skin disease occurs, any object the skin touches can become infected by the virus, bacteria, fungus or mite responsible for spreading the disease. Infectious skin diseases cause considerable problems for the members of the family, children, classmates and teachers in schools.
  • 118. Common skin infections during adolescence are acne, warts and tinea or fungal infections. Acne: (illustrator: Please make the face Filipino) Although most common among teenagers, acne can appear at any age, even among infants and people in their 30s and 40s. Acne, commonly called pimples or “zits”, is a skin condition characterized by the inflammation of the oil glands (sebaceous gland) and the hair follicles or cavity contained within tiny holes on the surface of the skin, called pores. This happens when oil (or sebum) from an oil gland that normally drains into a hair follicle and then gets out through an open pore on the surface of the skin is blocked. Dirt, debris, bacteria, and inflammatory cells build up on the clogged pore. A clogged pore is called a plug. The top of the plug may be dark (blackhead) or white (whitehead). Blackheads are caused by an excess of oil (sebum) in the pores. When the sebum reaches the surface of your skin, it hardens to a small, dark head. A whitehead is a plug of sebum that has not been exposed to air. When bacteria breed in the trapped oil, the skin will be inflamed. This inflamed red spot is called acne. If the plug breaks open, the material inside causes swelling and the formation of red bumps. Acne can be hereditary and can be triggered by:  High levels of humidity and sweating  Greasy or oily cosmetic and hair products  Certain drugs, such as steroids, testosterone and estrogen  Hormonal changes related to menstrual periods, pregnancy, birth control pills, or stress Management of Acne: Acne can be prevented, but if you go through it, the following steps are suggested to manage your acne:
  • 119. DO’S  DO remove make-up at night.  DO clean your skin gently with a mild, nondrying soap;  DO remove all dirt or make-up and wash once or twice a day, including after exercising.  DO shampoo your hair daily, especially if it is oily; comb or pull your hair back to keep the hair out of your face. DON’TS  DON’T scrub or wash your skin repeatedly.  DON’T touch your face with your hands or fingers.  DON’T wear tight headbands, baseball caps, and other hats.  DON’T squeeze, scratch, pick, or rub the pimples, although it might be tempting to do this; it can lead to infection and scarring.  DON’T use greasy cosmetics or creams. Look for water-based or cosmetics that do not clog pores. They have been tested and proven not to cause acne. If these practices do not clear up the blemishes, see a dermatologist. A dermatologist is a doctor who specializes in treating conditions that affect the skin, hair, and nails. Acne usually goes away after the teenage years, but it may last into middle age. The condition often responds well to treatment after 6 – 8 weeks, but it may flare up from time to time. Scarring may occur if severe acne is not treated. Warts: (Please revise illustration-make it Filipino) Although warts are mostly acquired by kids, teens and adults can get warts, too. It commonly appears on fingers, hands and feet. Warts are small, raised, rough, cauliflower-like infectious growths on the skin caused by a family of more than 100 types of viruses. Warts are normally not painful, but some warts itch and may cause pain, especially if they are on your feet. Warts are contagious and usually enter the body in an area of broken skin. Some people are more naturally resistant to wart virus and don’t easily get warts as other people do.
  • 120. There are different types of warts according to their shape and location:  Common warts are raised, rough growths that that usually appear on the hands, but can also grow anywhere on the body;   Flat warts are small, smooth, flattened, flesh-colored warts that usually appear on the face, neck and forehead;  Filiform are thread- or finger-like warts, most common on the face, especially near the eyelids and lips;  Genital warts appear on the genitals and between the thighs;  Plantar warts are hard sometimes painful lumps found on the soles of the feet;  Mosaic warts are groups of tightly clustered warts, commonly found on the hands or soles of the feet;  Subungual warts are cauliflower-like clusters of warts found under or around the fingernails and toenails Management of Warts Warts may be passed on to another person through touching. You can also get warts from using towels or other personal care things used by a person who has warts. It is always a good idea to wash your skin regularly and well. If you cut or scratch your skin, be sure to use soap and water because open wounds are more susceptible to warts. Wear waterproof sandals or slippers in public showers, locker rooms, and around public pools, which will also prevent you from getting other skin infections, like fungal infections. If you have warts, do not rub, scratch, or pick at them or you might spread the virus to another part of your body or cause the wart to become infected. Tinea or Fungal Infections: Fungal skin infections, called tinea, is a group of itchy, reddish and scaly skin infections caused by several types of mold-like fungi that live on the dead tissues of the skin, hair, and nails. Some Types of Tinea Infections: Ringworm affects the skin in different parts of the body, like the legs, chest and arms. It starts as a red, scaly patch or bump that becomes very itchy and uncomfortable over time. It may begin to look like a ring or a series of rings with raised, bumpy, scaly borders (the center is often clear).
  • 121.  Athlete's foot is a fungal infection found between toes that causes severe itchiness, redness and blisters.  Jock itch is ringworm that affects the groin or pubic area and the upper thigh; they may appear as red, itchy, scaly patches.  Ringworm of the scalp may start as a small sore on the scalp that resembles a pimple before becoming patchy, flaky, or scaly. It may cause some hair to fall out and may cause baldness.  Ringworm of the nails affects one or more nails on the hands or feet. The nails may become thick, white or yellowish, and brittle. Management of Tinea Infection: The most common sources of the fungi that cause tinea infections are other people. Ringworm is contagious and can easily spread from one person to another. You can get tinea infections or ringworms when you come into contact with the infected skin of someone suffering from the condition. You can also get them from inanimate objects contaminated by the fungus such as combs, unwashed clothing, and public showers or pool surfaces. The fungus that causes ringworm thrives in warm, moist areas. Ringworm is more likely to thrive when you are often wet (such as from sweating) and from minor injuries to your skin, scalp, or nails. It is also possible to become infected from contact with animals, like cats and dogs. DO’S  DO shower after contact sports.  DO wash sports clothing regularly.  DO shampoo regularly, especially after a haircut.  DO wash your hands often, especially after touching pets.  DO wear slippers in the locker room shower or at the pool. DON’TS  DON’T touch pets with bald spots.  DON’T share clothing, towels, hairbrushes, combs, or other personal care items.

Analyze the impact of the environmental problems on people’s health. Something to Ponder On Environmental health is concerned with everything in the natural and man- made environment that might affect our health. The natural environment includes land and water forms while man-made environment includes houses, buildings, bridges, neighborhoods, cities and provinces and the like. Focus on Environmental Health Draw a concept map of environmental health based on the definition stated above. Examples Our Natural Resources: Going…Going…Going The Central Intelligence Agency (2012) identified the most pressing environmental problems in the Philippines as follows: 1. Uncontrolled deforestation, especially in watershed areas 2. Soil erosion 3. Air and water pollution in major urban centers 4. Coral reef degradation 5. Increasing pollution of coastal mangrove swamps that are important breeding grounds of fish Environmental health Includes IncludeHealth of the Natural Environment Health of the Man- Made Environment
  • 128. Deforestation One hundred years ago, the Philippines had about 22,000,000 hectares of forest. In 2000, our forests had been trimmed down to 600,000 hectares (Imagine Echo Projects, 2008). Where did almost 97% of our forests go? This alarming loss of forests is not only happening in our country. It’s happening all over the world. We are losing forests at a faster rate than ever before-- approximately 16.5 million hectares a year. Now, forests cover only about 27 percent of the land surface of the earth. Deforestation is the destruction of big areas of our forests and this has been going on for many years. We are losing our forests because of—  Agriculture  Urbanization  Illegal logging  Mining  Forest fires Trees are cut down for the forests to become farms and to become towns and cities. These need lumber for houses, furniture, and many other necessities. We also export lumber to other countries, which necessitates cutting of trees. What is the effect of deforestation on our health? The International Rice Research Institute (IRRI) in Los Banos, Laguna estimates that it takes more than 4,000 liters of water to produce one kilo of rice (Imagine Echo Projects, 2008). Most of our freshwater comes from watersheds found in our forests. Deforestation has resulted in the decrease of freshwater for our farms. So, loss of forests means loss of food. It also means loss of other health products that come from the forests—clothing and medicines. Many of our people rely on traditional medicines, and most of them are forest products. Forests help prevent the appearance of communicable diseases. There are communicable diseases that result from deforestation, like dengue. These communicable diseases are usually transmitted by insect vectors, which in the case of dengue, are mosquitoes. When forests are lost, insect vectors and rodents who live in them lose their habitat, so they look for places where they can settle. If they cannot find other forests, then they settle in places where there are people. Smoke from forest fires and the burning of fields for planting (kaingin) causes respiratory problems. Smoke from forest fires can travel hundreds of kilometers and can threaten not only the health of people but can also cause death.
  • 129. There are laws and regulations that protect our forests, but these laws are either weakly enforced or not enforced at all. This is the reason for the existence of illegal logging practices. To maintain our forests, new trees are supposed to be planted to take the place of trees that have been cut down. Unfortunately, lack of funds makes reforestation difficult to sustain. Soil Erosion Soil erosion happens when soil and rock are moved from one place to another by wind, water, and gravity. It is brought about by natural and human activities. Strong winds and heavy rains cause soil erosion. People’s activities also cause soil erosion, like—  Deforestation  Building of roads  Agriculture  Urbanization—creation of towns and cities  Mining Soil erosion is a result of deforestation. The forest floor is covered by fallen and dead leaves and humus or natural compost made up of plant and animal matter. The leaves of trees serve as umbrellas and the forest floor serves as a mat that both protect the soil from the rain, such that rainwater is slowly absorbed by the soil. The roots of trees and plants in the forest likewise hold the soil together and prevent it from being washed away. Deforestation therefore exposes the soil to wind and water. - Help - Privacy Policy (Updated)/Legal - About Our Ads - Terms of Service - Copyright/IP Policy - Submit Your Site Powered by Bing™ http://images.search.yahoo.com/search/images?_adv_prop=image&fr=slv8- msgr&va=landslide+philippines+2012 Please revise illustration.

Soil erosion affects our health because most of our food comes from plants and our farmlands are, like our forests, fast disappearing at the rate of more than 10,000,000 hectares a year because of soil erosion, while more than 3.7 million people are malnourished (Pimentel as cited in Lang, 2006). Our nutrient-rich topsoil is lost when it is carried away by either wind or water. Soil also loses its fertility when the forest or farm is burned. Pimentel (2006) reports:  As a result of erosion over the past 40 years, 30 % of the world's farmland has become unproductive.  About 60 % of soil that is washed away ends up in rivers, streams and lakes, making waterways more prone to flooding and to contamination from soil's fertilizers and pesticides.  Soil erosion also reduces the ability of soil to store water and support plant growth, thereby reducing its ability to support biodiversity.  Erosion promotes critical losses of water, nutrients, soil organic matter and soil biota, harming forests, rangeland and natural ecosystems.  Erosion increases the amount of dust carried by wind, which not only acts as an abrasive and air pollutant but also carries about 20 human infectious disease organisms, including tuberculosis. "Soil erosion is second only to population growth as the biggest environmental problem the world faces," said David Pimentel, Professor of Ecology at Cornell University in the United States. Challenge 1. What is deforestation? 2. How are we losing our forests? 3. What are the effects of deforestation on our health? 4. Why is it difficult to stop deforestation? 5. What is soil erosion? 6. What are the causes of soil erosion? 7. What are the effects of soil erosion on our health? Air Pollution The Philippines is spending billions of pesos in income and time loss and health care expense because of air pollution (World Bank, 2009). According to World Bank, 1.5 million Filipinos of different ages are suffering from respiratory illness due to outdoor air pollution in urban areas, while almost a third of that number suffer from illnesses due to indoor air pollution.
  • 131. ILLUSTRATION OF SMOKE BELCHING JEEPNEY AND TRICYCLE; WOMAN COOKING USING WOOD AND STOVE INSIDE KITCHEN WITH INDOOR SMOKE; factory chimneys emitting dark smoke Outdoor air pollution (OIP) is caused mostly by exhaust from vehicles, especially jeepneys and tricycles, and factories. Smog (smoke+fog=smog) is caused by chemical reactions of pollutants, mainly exhaust from vehicles exhaust and factories. It is large-scale outdoor pollution. Urban areas where there are different kinds of vehicles and where there are many industrial establishments are often darkened by smog even during daylight, especially during the dry season. Particulates or Particulate matter (PM) is composed of tiny particles that pollute the air, including dust, dirt, soot, smoke, and liquid droplets. Some particulates are large and can be seen; others are so small that they can only be seen through the microscope. Particulates can stay in the air for a long time. When we breathe them in, they can cause respiratory diseases. Smoke coming from our activities—burning fuel, using gasoline for our vehicles, burning coal, oil and gas in factories and in generating electricity release gases (carbon dioxide, carbon monoxide, water vapor, chlorofluorocarbons or CFC, and others) in the atmosphere that add to global warming or warming of the Earth. The gases released in the atmosphere act like a blanket that traps the heat, making our temperature rise, thus warming the Earth. On the other hand, indoor air pollution (IAP) is common among poor families because they use firewood, dried animal manure and coal in cooking and their kitchen is poorly ventilated. Indoor smoke contains carbon monoxide and soot that have bad effects on the respiratory system when inhaled. Women and young children are the most affected by indoor air pollution because they are the ones who usually cook food and stay in the kitchen. Deaths due to indoor air pollution (IAP) are usually due to chronic obstructive pulmonary disease or COPD (for example, chronic bronchitis), pneumonia and lung cancer. Men, on the other hand, likewise suffer from respiratory disease but is made worse if they smoke, which makes indoor air pollution worse. If there is a smoker at home, all the members of the household sill suffer from indoor air pollution due to second-hand smoke (inhaling the smoke from the smoker) and third-hand smoke (inhaling smoke from clothes, bed sheets, curtains, and other things that absorb cigarette smoke. Other conditions and illnesses related to indoor air pollution are low birth weight, tuberculosis, heart disease, and cancer of the respiratory organs (WHO, 2011). In short, what is in the outside, goes in our insides; what is inside, stays in our insides.

  • 133. Water Pollution (picture on beautiful beach in the Philippines or any beautiful scenery with water—waterfall, river, beach, etc. Our country, the Philippines, will not be called Pearl of the Orient Seas for no reason. The Philippines is blessed with rich and beautiful natural resources that are the envy of other countries--land forms and water forms essential for our nation to live in comfort and for our country to progress economically. Our water resources include freshwater from our rivers, waterfalls, brooks, springs, lakes, and groundwater. Then we have saltwater from our coasts, seas, and oceans. There is water everywhere, our country being an archipelago, and it is sufficient for everyone… except in urban and coastal areas, which are highly populated. These areas experience water shortage, especially during the dry season. The National Capital Region (Metro Manila), Central Luzon, Southern Tagalog, and Central Visayas are the four urban regions experiencing problems in water quality and quantity from domestic and industrial sources during the dry season. Highly populated areas, unfortunately, are rapidly increasing because of our run-away population. Illustration of polluted water near the bay and dead rivers, dirty esteros So many people are using water for so many purposes—household and industrial, such that much of the waste water is no longer treated or disposed properly. They become pollutants in the process. These pollutants are in different forms from different sources: sewage, detergents, fertilizer, heavy metals, chemical products, oils, and even solid waste. Add to these, mercury pollution in bodies of water near abandoned mining areas, and we see that water pollution has become a big problem in our country. According to the Philippines Environment Monitor, in 2008, only about 1/3 or more than 36 % of our river systems were safe sources of public water supply. Up to 58% of our groundwater was found to be contaminated with disease-causing microorganisms and therefore unfit for drinking and recreational use. It needed water treatment. About 31% of illnesses reported were water-borne, including gastro- enteritis, diarrhea, typhoid, cholera, dysentery, hepatitis, and severe acute respiratory syndrome (SARS). Our growing population has likewise resulted in the urbanization of coastal areas. About 62% of our population lives in coastal areas. The urbanization of these areas is damaging our marine resources—coral reefs, mangroves and sea grasses. Gathering of corals has become a source of livelihood even if they are protected by environmental laws. Mangroves have been destroyed to give way to housing in coastal areas. Coral reefs and mangroves are home to our fish.
  • 134. Climate change caused by air pollution and resulting in rise in sea temperature has likewise destroyed our marine resources. The rising sea temperature has brought about fish kills and red tides, which happen during El Nino period. These events have resulted in the decreasing fish supply. We are a fish- eating people, and time will come when we might not have even fish to eat, if we do not do something about our present situation. The impact of water pollution costs our government an estimated Php67 Billion annually, which could be spent in better ways. The government has imposed pollution fines and environmental taxes in addition to environmental laws to control water pollution. Unfortunately, law enforcement is weak because of inadequate resources, poor database, and weak cooperation among different agencies and Local Government Units (LGUs).

  • 135. Lesson 2: Exposé: Community Health Problems Lesson Target: Identify pressing health problems in the community. Survey community health resources Make a plan of action Something to Ponder On Community health is concerned with maintaining, protecting and improving the health of people living in their immediate geographic area, while environmental health is concerned with all aspects of the natural and man-made environment that might affect human health. A community is made up of people who live in the same neighborhood, barangay or city-- people with the same interests or background, or even organizations that have something in common. You and your family are members of a community and your health is affected by other members as well as by the community itself. Your health problem can become a community health problem and the other way around. You and your family must therefore be responsible members of your community and be actively involved in solving community health problems. What’s the Problem? A problem must be clearly identified and properly stated to be able to work for its solution. You will learn how to identify community health problems and how to prioritize them so that you can identify the problem that needs to be solved right away. It will be helpful in the future if you will keep a PORTFOLIO of your Community Health Project so that you will remember the activities involved not only in doing a project but also in solving a problem. So, from here on, start writing a diary of your activities. Collect artifacts to show proof of activities you are participating in. At the end of the , you will submit your portfolio to your teacher. 1. Identify a problem or issue. a. Study the problems identified by the class in the pretest. b. Individually, choose the problem that you think needs to be solved right away and write it as No. 1 on the sheet of paper that will be given to you by your teacher. c. Choose the next most pressing number and rank it as No. 2. d. Then, think of the least pressing problem and rank it last. e. Choose No. 3, then second to the last, then No. 4 and so forth.
  • 136. What about the Problem? 2. Study the problem or issue. What information do you need to know more about the problem to be able to do something about it? You can do this through the K-W-H chart. As a group, fill in the K-W-H chart: What do we KNOW? What do we WANT to know? HOW will we get the answers? Divide the tasks among yourselves to find answers to the WANT and HOW questions. There are different ways of answering the questions. You might need to do these:  Go to the community to interview people, survey the resources, or observe people’s activities and behaviors  Go to the library to do research  Surf the internet to find more information Networking with Community People (Please Filipinize all the pictures. Illustrate different community resources in each hexagon: health centers/hospitals, police department, Agriculture office, etc.) .
  • 137. Health problems are solved and health status improved once there is a joint effort that brings the school and the community together. This necessitates a school to be health-promoting. To be effective, it has to recognize the potential of working closely with the community and to tap its resources, since the school is also part of the community. One of the key features of health-promoting schools is to strive to improve the health of the community by focusing on community health concerns and participating in community health projects (WHO, 1966). Now is your chance to bring your school and community together to work on a health project. Community Potentials 1. Study the resources in your community. 2. Who are the people doing health promotion? 3. What are the community health programs in place? 4. Are there individuals who might be interested in helping you implement your Community Health Action Project? Think about: • Clinics, hospitals and health-care providers • Infant health, child nutrition, family planning, HIV prevention, safety and other public health programs • Parent education and parent health-promotion projects  Local government programs • Non-Government Organization programs Include these in your K-W-H chart and plan how you can invite them to help you. What’ll we do with the Problem? 3. Plan the action to be taken. Here you will discuss possible actions that you can take to solve the problem. For each action, think of the consequences. This will help you choose which action to take. Ready for Action! Are you ready to implement your Community Health Project? What will you consider to more or less be sure that the implementation of your Project will go well?
