Study Notes
Principles of Growth and Development
- Growth and development are continuous processes occurring from conception to end of life; significant for pediatric nursing assessment.
- Early identification of developmental issues, even minor ones, can prevent severe consequences in later life.
- Development transcends physical changes, including cognitive, emotional, and social growth as children mature.
- Children not only grow in size but also acquire new skills, broaden thinking, build relationships, and develop a sense of self.
- Understanding developmental stages and milestones enables better support for children at each growth phase.
- Growth and development are interrelated, contributing uniquely to each individual's journey.
Growth Defined
- Growth refers to the increase in physical size of the entire organism or specific body parts through cell division and protein synthesis.
- It results in a quantifiable change assessed in height, weight, inches, centimeters, pounds, or kilograms.
- Growth is orderly and predictable, following a cyclical pattern, characterized by net gains in tissue size or mass.
- It reflects cell multiplication and the addition of intracellular substances, leading to increased functional complexity.
- Growth is considered a quantitative change as opposed to qualitative.
Growth Parameters
-
Weight: Most sensitive growth measurement. Typical milestones include:
- Birth weight doubles by 5 months.
- Birth weight tripled by 1 year.
- Birth weight quadruples by 2 to 2.5 years.
-
Height: Growth patterns include:
- 1 inch per month during the first six months.
- ½ inch per month from 7 to 12 months.
- Average height increase of 50% in the first year.
- Hormones:
- Estrogen influences height increase in females.
- Testosterone influences height increase in males.
- Height growth can stop with wisdom tooth eruption.
Principles of Growth
- Growth is continuous and influenced by hormonal interactions, genetics, and environmental factors.
- In the first three years, growth follows a curvilinear pattern; after that, it becomes linear.
- Growth in the first year mainly reflects inherited potential, while various factors contribute later.
- Significant growth spurts occur during the late fetal period and during puberty.
Phases of Growth
- Phase I: Hyperplasia (increase in cell number).
- Phase II: Hyperplasia combined with hypertrophy (increase in cell size).
- Phase III: Hypertrophy alone.
- Phase IV: Maturity (completion of growth).
