GROWTH AND
DEVELOPMENT
Infancy
Early Childhood
Middle Childhood
Adolescent

Definition of growth
Growth is a physical maturation
resulting an increase in size or numbers of
the body tissues and its various organs.

Development
It is the process of functional,
physiological maturation of the body. It is
the progressive increase in skills and
capacity to function.

Stages of Growth and Development
 Infancy
 Neonate: Birth to 1 month
 Infancy: 1 month to 1 year
 Early Childhood
 Toddler: 1-3 years
 Preschool: 3-6 years
 Middle Childhood
 School age: 6 to 12 years
 Late Childhood
 Adolescent: 13 years to approximately 18 years

Principles of Growth and Development
 Growth is an orderly process, occurring
continuously and unique to each child everywhere
in the world.
 G& D is proceed by stages and its sequence is
predictable.
 G& D depends on many factors especially
heriditary and environment.
 Society has strong influence on G& D of a children.

 Development proceeds from the simple to the
complex and from the general to the specific.
 Development occurs in a cephalocaudal and a
proximodistal progression.
 There are critical periods for growth and
development.
 There is a positive correlation between physical,
mental and emotional development of a child.

Growth Patterns
 The child’s pattern of growth is in a head-
to-toe direction, or cephalocaudal, and
in an inward to outward pattern called
proximodistal.

Why developmental assessment?
 Early detection of deviation in child’s
pattern of development
 Simple and time efficient mechanism to
ensure developmental progress
 Domains assessed: cognitive, motor,
language, social / behavioral and adaptive

Anthropometric assessment
 Weight
 Length
 BMI (Body mass Index)
 Circumference:
Head Circumference
Chest Circumference
Mid upper arm Circumference
 Dentition/eruption of teeth
 Osseous growth

1. Weight
 Weight of full term infant: 2.5-3.8 kg
 20% loss of weight in first week of life
 25-30gm/day increases till 3 months.
 40gm/month increases till 1 yr
 Doubled their birth weight in 5 months old.
 Tripled by one year of age.
 Four times in 2 yrs
 Five times in 3 yrs, Six times in 5 yrs
 7 times in7yrs, 10 times n 10 yrs

2.Length
 Height improvement indicates skeletal
growth.
 At birth average length is about 50cm.
 Increases to 60cm at 3 months, 70cm at 9
months.
 75cm-1 yr
 12cm increases in 2nd yr
 9cm increases in 3rd yr
 7cm increases in 4th yr

 6cm increases in 5th yr
 Doubles in height 4-5yrs
 Height increases in every year after the 5
years of age.

3.Body mass index (BMI)
 BMI= weight in Kg
Height in M2
 BMI remains constant up to 5 yrs of age.
 BMI >30kg/ M2 indicates obesity
 BMI <10kg/ M2 indicates malnutrition

4. Head circumference
 Average Head circumference at birth is
about 35 cm
 At 3 months it is about 40cm
 At 6 months it is about 43cm
 At 1 Year it is about 45cm
 At 2 Years it is about 48cm

Fontannelle closure
 Anterior Fontannelle & posterior
Fontannelle present at birth.
 Posterior Fontannelle closes early within
6-8 weeks of life
 Anterior Fontannelle closes at 12-18
months of life.
 Delayed closure results from malnutrition.
Hydrocephalus, con. Heart disease.

Fontannelle
Anterior Fontannelle Posterior Fontannelle

Chest circumference
 Also known as thoracic diameter
 At birth 2-8cm less than the head circumference.
 6-12 months head circumference becomes equal.
 After 1 yr head circumference more than chest
circumference.
 During birth chest circumference round in
shape, later becomes transverse diameter
increases.

Mid upper arm circumference
 It helps to find out the nutritional condition of children.
 At birth average MURC is about 12cm in a normal newborn.
 At 1 yr of age about 12-16cm
 1-5 yrs about 16-17cm
 At 12 yrs 17-18cm
 At 15 yrs 20-21 cm
 Measurement is taken from acromian process to oleocranon
process of ulna. The simple tape measures are used.

5. Dentition /eruption of teeth

Types of teeth
 Temporary for small face in small size
 Permanent teeth Bigger in size for growing
face.
Temporary teeth
Also called as Milk teeth/Deciduous teeth,
which erupt at the rate of one tooth every
month.
By the age of 2.5-3yrs all (20)temporary
teeth erupts.

Permanent teeth
 all temporary teeth replaced by permanent teeth.
 It starts from 6yrs and 12yrs.
 Third molar appears at 18 yrs or later in some
children.
Some babies born with teeth, it is called as natal teeth.
Malocclusion of teeth due to thumb sucking

6. Osseous growth
 Bony growth is essential for the proper height
of the child.
 Full term neonate have five ossification center.
 They are;
Distal end of femur
Proximal end of tibia
Talus
Calcaneous
Cuboid

Factors affecting growth and development
 Genetic
1. Sex
2. Race and nationality
 Environmental
1. Prenatal
Maternal
nutrition/Infections
2. Postnatal

Genetic factors
 Characteristics such as
height, body structure, color
of skin, eyes and hair
depends upon inherited
genes from parents.
 Some familial diseases also
affected the growth of
children

Environmental factors
1. Prenatal factors
Intrauterine environment is an important
predominant factor of growth and development.
 Maternal malnutrition
 Maternal infections
 Maternal substance abuse
 Maternal illness
 Hormones- Thyroxine es the skeleton growth
 Uterine malformations

2. Postnatal environmental factors
 Growth pattern
 Nutrition

Growth and development of Infant
(0-1yr)

Physical growth of normal infant
Weight : the infant gains :
- Birth to 4 months → ¾ kg /month
- 5 to 8 months → ½ kg / month
- 9 to 12 months → ¼ kg /month
The infant will double his birth wt by 4-5
months and triple it by 10-12 months of
age

Calculating infant’s weight
Infants from 3 to 12 months
Weight = Age in months + 9
2
Wt of 7 months old infant = 7+9 = 16 = 8 kg
2 2

Height
• Length increases about 3 cm /month
during the 1st 3 months of age,
• then it increases 2 cm /month at age of 4-
6 months,
• Then, at 7 – 12 months, it increases 1 ½ cm
per month

Growth and development of
Toddler (1-3 yrs)

Physical growth
Weight:
The toddler's average weight gain is 1.8 to 2.7
kg/year.
Formula to calculate normal weight of children
over 1 year of age is
Age in years X 2+8 = ….. kg.
e.g., The weight of a child aging 4 years
= 4 X 2 + 8 = 16 kg

Height:
• During 1–2 years, the child's height
increases by 1cm/month.
• The toddler's height increases about
10 to 12.5cm/year.

Formula to calculate normal height
Age in years X 5 + 80 =
cm.
e.g., the length of 2 years old child
= 2 X 5 + 80 = 90cm

Teething:
• By 2 years of age, the
toddler has 16
temporary teeth.
• By the age of 30
months (2.5 years),
the toddler has 20
teeth

It begins with the appearance of secondary sex
characteristics and ends when somatic growth is
completed and the individual is psychological
mature.

Adolescent

• Growth in height ceases at 16 or 17 years in females and 18 to 20in
males

Physiological growth:
Pulse: Reaches adult value 60–80 beats/min.
Respiration: 16–20C/minute.
NB: The sebaceous glands of face, neck and chest
become more active. When their secretion
accumulates under the skin in face,
acne/pimples will appear.

Appearance of secondary sex characteristics
1- Secondary sex characteristics in girls:
• Increase in transverse diameter of the pelvis.
• Development of the breasts.
• Change in the vaginal secretions.
• Growth of pubic and axillary hair.
• Menstruation (first menstruation is called menarche,
which occurs between 12 to 13 years).

Secondary sex characteristics in boys:
• Increase in size of genitalia.
• Swelling of the breast.
• Growth of pubic, axillary, facial and chest hair.
• Change in voice.
• Rapid growth of shoulder breadth.
• Production of spermatozoa (which is sign of
puberty).

Emotional development:
This period is accompanied usually by
changes in emotional control. Adolescent
exhibits alternating and recurrent episodes of
disturbed behavior with periods of quite one.
He may become hostile or ready to fight,
complain or resist every thing.
