Growth & Devt[1].

  2. 2. I. PHASES OF GROWTH AND DVELOPMENT <ul><li>Process – sequence is orderly and predictable; rate tends to be variable within ( more quickly/ slowly) and between (earlier/later) individuals </li></ul><ul><ul><li>growth – increase in size (height and weight; tends to cyclical, more rapid in utero, during infancy, and adolescence </li></ul></ul>
  3. 3. 2. developmental – maturation of phychosocial systems to more complex state <ul><li>Developmental tasks – skills and competencies associated with each developmental stage that have an effect on subsequent stages of development </li></ul><ul><li>Developmental milestone – standard of reference by which to compare the Childs behavior at specific ages </li></ul><ul><li>Developmental delay(s) – variable of developmental which lags behind the range of a given age </li></ul>
  4. 5. Principles of Growth <ul><li>Children are individuals, not little adults, who must be seen as part of a family. </li></ul><ul><li>Children are influenced by genetic factors, home and environment, and parental attitudes. </li></ul><ul><li>Chronologic & developmental ages of children are the most important contributing factors influencing their care. </li></ul>
  5. 6. <ul><li>Play is a natural medium for expression, communication, and growth in children. </li></ul><ul><li>Growth is complex, with all aspects closely related </li></ul><ul><li>Growth is measured both quantitatively and qualitatively over a period of time. </li></ul><ul><li>Although the rate is uneven, growth is continuous and orderly process: </li></ul>Principles of Growth
  6. 7. Principles of Growth <ul><li>7.a. Infancy : most rapid period of growth </li></ul><ul><li>b. Preschool to puberty : slow and uniform rate of growth. </li></ul><ul><li>c. Puberty : (growth spurt) second most rapid growth period. </li></ul><ul><li>d. After Puberty : decline in growth rate till death. </li></ul>
  7. 8. <ul><li>There are regular patterns in the direction of growth and development, such as the cephalocaudal law (from head to toe) and from proximodistal law (from center to periphery) </li></ul>Principles of Growth
  8. 9. <ul><li>Different parts of the body grow at different rates: </li></ul><ul><ul><li>Prenatally: head grows the fastest. </li></ul></ul><ul><ul><li>During the first year: elongation of trunk dominates </li></ul></ul><ul><li>Both rate and pattern of growth can be modified, most obviously by nutrition. </li></ul>Principles of Growth
  9. 10. <ul><li>There are critical or sensitive periods in G&D, such as brain growth during uterine life and infancy. </li></ul><ul><li>Although there are specified sequences for achieving G&D, each individual proceeds at own rate. </li></ul><ul><li>D is closely R/T the maturation of the nervous system; as primitive reflexes disappear, they are replaced by a voluntary activity. </li></ul>Principles of Growth
  10. 11. Physiological Characteristics of Growth <ul><li>Circulatory System: </li></ul><ul><ul><li>Heart rate decreases with increasing age </li></ul></ul><ul><ul><ul><li>Infancy: 120 bpm </li></ul></ul></ul><ul><ul><ul><li>One year: 80 to 120 bpm </li></ul></ul></ul><ul><ul><ul><li>Childhood: 70 to 110 bpm </li></ul></ul></ul><ul><ul><ul><li>Adolescence to adulthood: 55 to 90 bpm </li></ul></ul></ul>
  11. 12. Blood pressure increases with age <ul><li>The 50 th percentile ranges from 55 to 70 mmHg diastolic; 100 to 110 mmHg systolic </li></ul><ul><li>These levels increase about 2 to 3 mmHg / yr. starting at age 7 yrs. </li></ul><ul><li>Systolic pressure in adolescence: higher in males than in females </li></ul>
  12. 13. Hemoglobin <ul><li>Highest at birth, 17 g/100 ml of blood; then decreases to 10 to 15 g/100 ml by 1 year. </li></ul><ul><li>Fetal Hgb (60% to 90% of total Hgb) gradually decreases during the first yr to less than 5%. </li></ul><ul><li>Gradual increase in Hgb level to 14.5 g/100ml between 1 & 12 yrs. </li></ul><ul><li>Level Higher in males than in females </li></ul>

  16. 17. Urinary System <ul><li>Premature & full term Newborns have some inability to concentrate urine. </li></ul><ul><ul><li>Specific Gravity: (Newborn): 1.001 to 1.02 </li></ul></ul><ul><ul><li>Specific Gravity: (Others): 1.002 to 1.03 </li></ul></ul><ul><li>GFR greatly increased by 6 months of age; reaches adult values between 1 & 2 years; gradually decreases after 20 years. </li></ul>
  17. 18. Digestive System <ul><li>Stomach size is small at birth; rapidly increases during infancy and childhood </li></ul><ul><li>Peristaltic activity decreases with advancing age </li></ul><ul><li>Blood Glucose levels gradually rise from 75 to 80 mg/100 ml of blood in infancy to 95 to 100 mg during adolescence. </li></ul>
  18. 19. <ul><li>Premature infants have lower blood glucose levels than do full-term infants. </li></ul><ul><li>Enzymes are present at birth to digest proteins and a moderate amount of fat but only simple sugars (amylase is produced as starch is introduced) </li></ul><ul><li>Secretion of Hcl acid & salivary enzymes increases with age until adolescence; then decreases with advancing age. </li></ul>Digestive System
  19. 20. Nervous System <ul><li>Brain reaches 90% of total size by 2 yrs of age. </li></ul><ul><li>All brain cells are present by the end of the first year, although their size & complexity will increase. </li></ul><ul><li>Maturation of the brainstem & spinal cord follows Cephalocaudal & Proximodistal Laws. </li></ul>

  45. 48. Robert Havighurst: Developmental Theorist
  46. 49. <ul><li>&quot;The developmental-task concept occupies middle ground between two opposed theories of education: the theory of freedom— that the child will develop best if left as free as possible , and the theory of constraint— that the child must learn to become a worthy, responsible adult through restraints imposed by his society. </li></ul>
  47. 50. <ul><li>A developmental task is midway between an individual need and societal demand. It assumes an active learner interacting with an active social environment&quot; (1971, p. vi).  </li></ul>
  48. 51. The Developmental Task Concept <ul><li>From examining the changes in your own life span you can see that critical tasks arise at certain times in our lives. Mastery of these tasks is satisfying and encourages us to go on to new challenges . Difficulty with them slows progress toward future accomplishments and goals. </li></ul>
  49. 52. six major age periods: <ul><li>infancy and early childhood (0-5 years), </li></ul><ul><li>middle childhood (6-12 years) </li></ul><ul><li>adolescence (13-18 years), </li></ul><ul><li>early adulthood (19-29 years), </li></ul><ul><li>middle adulthood (30-60 years), and </li></ul><ul><li>later maturity (61+). </li></ul>

  60. 63. Lawrence Kohlberg Stages of Reasoning
  61. 64. <ul><li>Stage 1 - Obedience and Punishment </li></ul><ul><ul><li>The earliest stage of moral development is especially common in young children, but adults are capable of expressing this type of reasoning. At this stage, children see rules as fixed and absolute. Obeying the rules is important because it is a means to avoid punishment. </li></ul></ul><ul><li>Stage 2 - Individualism and Exchange </li></ul><ul><ul><li>At this stage, children account for individual points of view and judge actions based on how they serve individual needs. In the Heinz dilemma, children argued that the best course of action was whichever best-served Heinz’s needs. Reciprocity is possible, but only if it serves one's own interests. </li></ul></ul>Level 1. Preconventional Morality
  62. 65. Level 2. Conventional Morality <ul><li>Stage 3 - Interpersonal Relationships </li></ul><ul><ul><li>Often referred to as the &quot;good boy-good girl&quot; orientation, this stage is focused on living up to social expectations and roles. There is an emphasis on conformity, being &quot;nice,&quot; and consideration of how choices influence relationships. </li></ul></ul><ul><li>Stage 4 - Maintaining Social Order </li></ul><ul><ul><li>At this stage of moral development, people begin to consider society as a whole when making judgments. The focus is on maintaining law and order by following the rules, doing one’s duty, and respecting authority. </li></ul></ul>
  63. 66. Level 3. Postconventional Morality <ul><li>Stage 5 - Social Contract and Individual Rights </li></ul><ul><ul><li>At this stage, people begin to account for the differing values, opinions, and beliefs of other people. Rules of law are important for maintaining a society, but members of the society should agree upon these standards. </li></ul></ul><ul><li>Stage 6 - Universal Principles </li></ul><ul><ul><li>Kolhberg’s final level of moral reasoning is based upon universal ethical principles and abstract reasoning. At this stage, people follow these internalized principles of justice, even if they conflict with laws and rules. </li></ul></ul>
  64. 67. Criticisms of Kohlberg's Theory of Moral Development: <ul><li>Does moral reasoning necessarily lead to moral behavior? Kohlberg's theory is concerned with moral thinking, but there is a big difference between knowing what we ought to do versus our actual actions. </li></ul><ul><li>Is justice the only aspect of moral reasoning we should consider? Critics have pointed out that Kohlberg's theory overemphasizes the concept as justice when making moral choices. Other factors such as compassion, caring, and other interpersonal feelings may play an important part in moral reasoning. </li></ul><ul><li>Does Kohlberg's theory overemphasize Western philosophy? Individualistic cultures emphasize personal rights while collectivistic cultures stress the importance of society and community. Eastern cultures may have different moral outlooks that Kohlberg's theory does not account for. </li></ul>
  65. 68. C. Chronological phases <ul><li>Prenatal – conception until birth: rapid growth and development </li></ul><ul><li>Neonatal – birth until 4 wk of age: adjustment to extra uterine life </li></ul><ul><li>Infancy – 4 wk to 12 or 18 mo (upright locomotion); rapid and incremental growth and motor, cognitive, and social development (see table XIV – 2) </li></ul>

  125. 128. D. factors affecting growth and development
  126. 129. 1. Genetic defects <ul><li>Increased risk in certain groups of people who demonstrate increased incidence of specific defects, e.g., African Americans for sickle cell disease, Northern European descendants of ashkenazic Jews for Tay-Sachs disease, Mediterranean ancestry for thalassemia; couples with a history of a chills with a defect; family history of a structural abnormality or systemic disease that may be hereditary; prospective parents who are closely blood-related; women over 40 </li></ul>
  127. 130. Chromosomal alteration – may be numeric or structural <ul><li>Down’s syndrome (trisomy 21) – increased in women over 35 y; characterized by a small, round head with flattened occiput; low set ears ‘ large fat pads at the nape of a short neck; protruding tongue; small mouth and high palate; epicanthal folds with slanted eyes; hypotonic muscles with hypermobility of joints; short, broad hands with inward curved little finger; transverse simian palmar crease; mental retardation </li></ul>
  128. 131. <ul><li>Turner’s syndrome (female with only one X) – characterized by stunted growth, fibrous streaks in ovaries, usually infertile, no intellectual impairment; occasionally perceptual problems </li></ul><ul><li>klinefelter’s syndrome (male with extra X) – normal intelligence to mild mental retardation; usually infertile </li></ul>
  129. 132. Autosomal defects – defects occurring in any chromosome pair than the sex chromosomes
  130. 133. <ul><li>Autosomal dominant – abnormal gene overshadows the normal gene, thus the condition is always demonstrated when the gene is present; the affected parent has a 50% chance of passing on the abnormal gene in each pregnancy </li></ul>
  131. 134. <ul><li>Autosomal recessive – requires transmission of abnormal gene from both parents for expression of condition </li></ul><ul><li>Sex-linked transmission traits – trait carried on sex chromosome (usually the X chromosome); may be dominant or recessive, but recessive is more prevalent; e.g., hemophilia, color blindness </li></ul>
  132. 135. Inborn errors of metabolism <ul><li>disorders of protein, fat, or carbohydrate metabolism reflecting absent or defective enzymes that generally follow a recessive pattern of inheritance </li></ul>
  133. 136. <ul><li>Phenylketonuria (PKU) – uncommon disorder due to autosomal recessive gene, creating a deficiency in the liver enzyme phenylalanine hydroxylase, which metabolizes the amino acid phenylalanine; results in the failure to metabolize phenylalanine, allowing its metabolites to accumulate in the blood; toxic to brain cells </li></ul>
  134. 137. <ul><li>Tay – Sachs – autosomal recessive trait resulting from a deficiency of hexosaminidase A, resulting in apathy, regression in motor and social development, and decreased vision </li></ul><ul><li>Cystic fibrosis (mucoviscidosis or fibrocystic disease of the pancreas) – an autosomal recessive trait characterized by generalized involvement of exocrine glands, resulting in altered viscosity of mucus – secreting glands throughout the body </li></ul>

  136. 139. Assessment of growth and development
  137. 140. Growth <ul><li>Repeated measurements must be done and recorded accurately on regain basis to establish pattern and identify deviations; at least five times in first year and then yearly at very well – child visit and sick-child visit as appropriate </li></ul>
  138. 141. <ul><li>Assessing length/height- infant or toddler positioned supine on exam table with legs extended is measured from crown of head to heels using flexible nonstretchable tape, while another person maintains child’s position; for the older child, standing measurement is easer and more accurate </li></ul>
  139. 142. Standardized growth chart <ul><li>Individual’s length/height, weight, and head and chest circumference (until 3 y) is assesses in relation to general population, to previous pattern, and to each other </li></ul><ul><li>Necessary to reevaluate and report measurements >97th percentile and <3rd percentile or deviations from established pattern </li></ul>
  140. 143. Development <ul><li>evaluates current developmental function, identifies need for follow-up, helps parents to understand the child’s behavior and prepare for new experiences, and provides basis for anticipatory guidance </li></ul>
  141. 144. <ul><li>Evaluation should include all the subsystems of development, biophysical (gross and fine motor), cognitive, language, social, affective </li></ul><ul><li>Developmental tools </li></ul>
  142. 145. Denver Developmental Screening Test (DDST) <ul><li>evaluates children from birth to 6 y in four skill areas: personal – social, fine motor, language , gross motor </li></ul><ul><ul><li>Age adjusted for prematurity by subtracting the number of months preterm </li></ul></ul><ul><ul><li>Questionable value in testing children of minority. ethnic groups </li></ul></ul>

Moderate (IQ range 40 to 54) <ul><li>Preschool-age children with moderate MR show noticeable delays in development of motor skills and speech. </li></ul><ul><li>Older children can learn simple communication, health and safety habits, and self-help skills. </li></ul><ul><li>They are not able to gain useful reading or math skills. </li></ul><ul><li>As adults, they can do simple tasks under special conditions and can travel alone in familiar places. </li></ul><ul><li>They usually cannot live completely by themselves. </li></ul>
  146. 149.
