2. DEFINING ADOLSCENCE
 The period of adolescence begins with
biological changes of puberty and ends with
the role and work of adult life .

3. THREE STAGES OF ADOLESCENCE
 Early adolescence
 Middle adolescence
 Late adolescence

4. Adolescence is period of
transition in terms of physical,
cognitive and socio-emotional
changes, physical transition being
particular coupled with sexual
transformation.

5. PUBERTY CHANGES
In all cultures, biological changes comprises
the major transition from childhood to early
adolescence. This is manifested by a change
in physical appearance, a more rapid rate of
development (next to the speed of growth of
the fetus in the uterus) known as growth
spurt. The phenomenon commonly result in
the feeling of awkwardness and unfamiliarity
with bodily changes.

6. In addition, alternations in
sleeping habits and parent-
adolescent relationship may
be experienced
accompanying puberty
changes.

7. THE GROWTH SPURTS
The growth hormone conditions gradual
increases in body size, and weight, but
hormones flooding occurs during
adolescence causing an acceleration
known as the growth spurt.
Body changes include change in
body dimensions (leg length, shoulder
width, trunk growth rather than leg
growth).

8. In girls, the growth spurt generally begins
at age 10 reaching its peak at age 11
and-a-half, and decreasing at age 13,
while slow continual growth for several
more years
At age 16 and girls reach 98% of
their adult height.

9. SEXUAL MATURITY
HORMONES – are recognize to be powerful
and highly specialized chemical substances
that interact with body cell. The triggering by
the hormones of the pituitary glands signal
the entire process of sexual maturation.
During the process, GONADOTROPIC
HORMONES are secreted by the anterior
pituitary, which lies beneath the base of the
brain and are situated approximately at the
geometric center of the human head.

10. GONADS are the ovaries in the female
and the testis in the male, are then
stimulated by the gonadotropic
hormones, in term stimulating their own
hormones. When the male testis is
stimulated by the gonadotropic
hormones, testosterone is secreted,
while estrogen is secreted when the
female is stimulated.

11. Secondary male sex characteristics are stimulated
by testosterone, comprised by growth of the
testis and scrotum (recognized to be the first
sign of puberty), penis and first pubic hair; the
capacity for ejaculation, the growth spurt, voice
change , facial hair development/beard growth,
and continuing growth of pubic hair. The
acceleration of the growth precedes the first
appearance of facial hair growth. Occurring late
in puberty, the lowering of the voice, cause by
enlargement of the larynx and double
lengthening of the vocal cords, is viewed to be
the most obvious aspect of adolescent

12. In the contrast with menarche, sperm ache
signals the first sign of puberty and sexual
maturity in boys at about age 12 or 13, boys
experience the enlargement of the thesis and
the manufacture of sperm in the scrotum, most
likely experiencing the first ejaculation of
semen-a sticky fluid produced by the prostate
gland. The need to discharge semen occurs
more or less periodically following pressure
caused by the production of seminal fluid by
the prostate gland. Nocturnal emissions or
“wet dream” occur during sleep often caused
by sexual dreams.

13. THE SECULAR TREND
The striking tendency for children to become
larger at all ages has become perceived the
past 100 years. Known as the SECULAR
TREND, the phenomenon reflects a more rapid
maturation compared with occurring in previous
millennia. In 1880, for example, the average
age at which girls and their first menstrual
period in which girls and their first menstrual
period in well nourished industrial societies was
15 and 17 years. This is not true, however, in
depressed societies wherein this period is a bit

14. One hundred years ago, boys
reached their adult height at age 23
and 25 and girls at ages 19 and 20
today, maximum height is reached
between 18 and 20 years for boys
13 and 14 for girls.

15. ADOLESCENT SLEEPING HABBIT
Teenagers are not getting enough sleep, and
would want more sleep. Actually, lack of sleep
is likely caused by changes in adolescence
behavioral patterns. Teens often stay up late
because they enjoy it, especially with the
advent of internet, music listening, video
watching. About 90% of teenager high school
student report going to bed later than midnight.
Socializing with peers add to the problem,
causing difficulties in waking up early and
causing teenager to struggle to stay alert and

16. EXPLORATION
Adolescents become aware of changes in
sexuality, thus undergoing a period of
exploration and adjustment. Learners from
sectarian (religious and gender exclusive)
schools are more likely to consider sexual
opened to dangerous, if not sinful. The case
is not perceived among non-sectarian exist
relating to heterosexual relationship and
early pregnancy among students in non-
exclusive schools.

17. PLUSES AND MINUSES IN EARLY OR LATE
MATURATION
Early or late maturation deserve due
consideration, as this can be a factor for
adolescent acceptance and comfort or
satisfaction with his/her body image. Among
girls, physical changes are more dramatic,
but perceptions of not being well developed
as compared with their peers can be a cause
for timidity or shyness, if not frustration.

18. In the late maturing boys, the slack in the growth
in the body build, strength, motor performance
and coordination may inhibit their performance
in curricular and extra-curricular activities, such
as sports. Being physically weaker, shorter and
slimmer would make them less apt to be
outstanding in leadership activities and in
sports. On top of these, late maturing teens are
seen by their peers as being more childish,
more inhibited, less independent, less self
assuring, and less worthy of leadership roles.

19. THE IDEAL MASCULINE AND FEMININE
PHYSIQUES
Most adolescence desire an “Ideal Body”,
which is the same as being attractive or
handsome in face (features of the eyes,
nose, lips, hair, etc.) and in body (tall,
and muscular for boys and tall and
slender for girls).

20. In the developed countries like U.S. about
10% of adolescents have been known to
take anabolic steroids in tablet or in
injectable form for cosmetic and athletic
performance purposes. It is important to
forewarn adolescents about the severe
harmful effects of long term use of ,
steroids: liver dysfunction and damage to
the productive system.

21. Short term effect are hair loss, severe
acne, high blood pressure, shrunken
testicles, and low sperm production. Girl
users develop irreversible masculine
characteristics, such as growth of facial
hair. Steroids may also foster
aggressive and destructive behavior.
Finally, giving up the drug may lead to
depression and suicide.

22. ADOLESCENTS AND NUTRITION
Necessary for adolescent years are sufficient
amounts of vitamin B12 (found in animal
proteins), calcium, zinc, iron, riboflavin and
vitamin D. Magic diet schemes suggested by
advertising and magazines to lose weight,
give a radiant hair, whiten the skin, etc.
shouid be met with caution.

23. The vegetarian fad can also be disastrous
especially to adolescents who need
vitamin, minerals and protein which
vegetable diets cannot provide.
Vegetable intake is good, but this
should be balanced with food intake to
form high-quality nutrition including
eating protein sources such as milk,
dairy products and eggs.

24. It is a recognized fact that teens are the
poorest eaters among age group, as
they often skip meals, frequently take
snack foods (hamburger, fries, pizza,
soft drinks, etc.) at fast food eateries.

25. THE IDEAL BODY
It’s important that adolescent feel
confident about their body (facial looks,
body size, color of skin, etc.) depend on
genetic heritage witch must generally be
respected. However with advancement
in hair color and skin are mo longer
impossible.

26. There is more to body image than physical
looks and these concern good habits in
relation to:
 Cleanliness and grooming.
 Proper wearing of clothes following current
styles.
 Erect bodily posture
 Eye contact while communicating
 Decorum (good form and confidence) and
decency
