Growth and development
➢ Growth : - the term growth refers to an increase in size of the body parts due to
multiplication of cells and increase in the intercellular substance.
➢ Development :- development refers to physiological maturation. It is progressive
increase in skill and capacity to function.
➢ Major developmental periods.
▪ Prenatal period - conception to birth
▪ Neonatal period - 4 birth to four weeks .
▪ Infancy - 4 four weeks to one year
▪ Toddler - 4 from one to three years
▪ Pre-school - 4 (early childhood) from three to six years
▪ School age - 4 (late childhood) from six to twelve years
▪ Adolescence - from puberty to the beginning of adulthood (13 years to 18 years)

Parameters of growth and development
(anthropometry)
 The best indication of good overall health in an infant is steadily increasing
weight, height, head and chest circumference.
 Other parameters are MUAC, dentition and suture.
❑1. weight :-
• The average new-born weight is about between 2.5 to 3.5 kg.
• The birth weight usually doubles by 5 months and triples by one year of age.
• After the first year weight gain levels off to approximately 4-6 lbs per year until
the pubertal growth spurt.
• The instrument used in weight measurement is weighing scale (electrical and
salter scale).

4.
Parameters.………(continue)
• Formula for calculating weight –
• 1 to 12 months wt. = age (in months) +9
2
1 to 6 years. Wt. = {age (in years) x 2} + 8
7 yr. To 12 yr. Wt. = age (in yr.) x 7 – 5
2
❑Height / length : -
• The new born has an average length of 50 cm (18-20”).
• There is increase of 50% of the birth length by 12 month of age (75 cm ).
• The height of older child is taken when he is weighed. The infant is measured
while lying on a flat surface or on an infantometer.
• Height at 2yr – 87 cm , @3yr – 94 cm, @ 4yr – 100 cm ( double of birth height).

5.
Parameters………….
❑ MUAC ( mid upper arm circumference) :-
• It taken up to age of 6 months to 59 months of age.
• Instrument is used in measurement – MUAC tape.
• Colour code in MUAC tape –
Red – less than 11.5 cm – SAM (severe acute malnutrition)
yellow – 11.5 to 12.4 cm - MAM ( moderate acute malnutrition)
green – more than 12.5 cm – normal range
Tuesday, 09 August 2022 5

6.
Parameters………..
❑Head circumference : -
• Normal head circumference at birth is about 33cm.
• After one year of age head circumference is about 35 cm.
• Increase of ½ inch (1.3 – 1.5 cm) per month b/w age 1 to 6 month.
• Increase of ¼ inch (0.5 to 0.64 cm ) per month b/w ages of 6 month to 12
months. By the age of one year head circumference is 45 cm.
❑Chest circumference : -
• Normal chest circumference at birth is about 31 cm.
• At one year of age head and chest circumference equalize about 45 cm .
• Chest circumference is smaller than head circumference at birth.

Parameters……….
❑Dentition :-
• Teething is the period of eruption of primary teeth also called as the
deciduous teeth because they are shed off.

(in months)
Teeth average Age
(in months)

Parameters………
❑Suture (fontanel) : -
• The posterior fontanel measures 1x1 cm at birth and normally closed at
two months ( 1 ½ month) of age.
• The anterior fontanel measures 3.5 x 3.5 cm at birth and normally closed
at 18 months (1 ½ yrs.) of age.

Factors influencing growth & development
 Growth and development influenced by …
 1. Heredity
 2. environment
(i) intrauterine environment
(ii) social & economical condition
(iii) cultural influences
(iv) nutrition
Tuesday, 09 August 2022 9

10.
Factors………
➢1. heredity factors : -
• Heredity refers to the genetic condition of an individual which is
established during conception.
• Color of the eyes, hair, facial features, structure of the body, physical
peculiarities, blood group are determined antiraly by heredity, sex is
determined at conception.
• Some congenital disorders due to heredity –
• Genetic disorders – haemophilia, colour blindness, phenylketonuria.
• Chromosomal disorders – down syndrome, tuner syndrome, Klinefelter
syndrome.

11.
Factors…………
➢2. environmental factors : -
• Environment is a most important affecting factor of growth and
development of child.
❖(i) Intrauterine environment : -
• intrauterine environment is the function of maternal circulatory pattern
which provides nutritional and gas exchange.
• Harmful prenatal factors –
- nutritional deficiencies when the mother’s diet is insufficient in quality ,
anemia in the mother.
- mechanical problems like malposition in utero.
Tuesday, 09 August 2022 11

12.
Factors……
- metabolic endocrine disturbance like diabetes.
- infectious disease during pregnancy – ToRCH
T – toxoplasmosis
o – other infections
R – rubella
C – cytomegalo virus
H – herpes simplex & syphilis
- smoking and use of alcohol and drugs may result in prematurity or
deformity of child.
Tuesday, 09 August 2022 12

13.
Factors………
❖(ii) Social & economic conditions : -
• Poverty, crowded living conditions, ignorance and lack of interest on the
part of the parents may lead to retardation of the 6ormal growth and
development of children.
❖(iii) cultural influences : -
• The effect of a particular culture on a child begins the way a cultural group
takes care of the female children of its community and the women.
• Gender discrimination and other issues affects the growth of children.
Tuesday, 09 August 2022 13

14.
Factors…….
❖(iv) Nutrition : -
• It has been established that prolonged malnutrition of the expectant
mother is one of the most common causes of low birth weight, fetal and
neonatal deaths and incurably damaged infants.
• Adolescent girls have the poorest diet in most cases because of their desire
to be slim.

Characteristics of development
 There are certain basic predictable characteristics of this basic blue print of
development. There are as follows : -
✓ Development is similar for all.
✓ Development proceeds from general to specific.
✓ Development is continues.
✓ There is co- ordination in development.
✓ Development proceeds at different rates.
✓ Development comes from maturation and learning.
✓ There are individual differences.
✓ Early development is more significant than later development.
✓ Development proceeds by stages such as fetal, infancy, babyhood and adolescent.
✓ There are predictable patterns of physical development.

 The inborn reflexes present at the time of birth and occur in a predictable
fashion.
 If these reflexes persists beyond the normal age limit indicates cerebral
damage or immaturity.
➢Moro’s reflex : -
• It is initiated by any sudden movement of the neck.
• It consists of rapid abduction and extension of upper limbs and opening
