- Growth is the increase in size of organs and body, and is assessed through physical anthropometry such as weight, height, head circumference, and mid-upper arm circumference.
- Periodic growth assessment allows for early detection of growth faltering which can indicate undernutrition, infection, or disease.
- Factors like genetics, nutrition, hormones, environment, and socioeconomic status can influence growth.
- Growth charts are used to evaluate if a child's growth is normal based on weight for age, height for age, and BMI for age.
- Deviations from normal growth patterns on charts may indicate malnutrition or underlying health conditions.
3. Definition of Growth
•Growth is increase in size of organs and
body.
•It is quantitative change and refers to physical
maturation of the body.
4. Importance of growth assessment
• Growth is fundamental characteristic of
childhood.
• Normal growth is indicator of optimum
health.
• Deviation from the normal pattern is
indicative of pathological process.
• Periodic assessment facilitates early
detection of growth faltering, which may
be first manifestation of
undernutrition/infection/ disease.

9. Laws Of Growth
1. Continuous and orderly process.

• Brain growth – 3rd trimester and 1st year of
life.
• Lymphoid growth – Mid childhood
