Write a short note on Growth Charts.
Definition
- A growth chart is a graphic tool on which a child's serial anthropometric measurements are plotted against age (or against each other) and compared with reference standards, to monitor growth over time.
- It is the cornerstone of growth monitoring.
Standard VS Reference
- WHO Child Growth Standards (2006) — 0–5 years; a prescriptive standard (how children should grow, derived from healthy, breastfed children across 6 countries).
- IAP charts (2015) — 5–18 years Indian children (a descriptive reference).
- In India, the Mother & Child Protection (MCP) card uses WHO standards; the older 'Road-to-Health card' was WHO-based.
Parameters Plotted
- Weight-for-age; Length/Height-for-age; Weight-for-height/length; BMI-for-age; Head-circumference-for-age.
- Represented as percentile lines (3rd, 15th, 50th, 85th, 97th) or Z-scores (SD lines).
Interpretation (z-scores)
| Indicator (Z-score) | Interpretation |
|---|---|
| Weight-for-height < −2 SD | Wasting (acute undernutrition) |
| Weight-for-height < −3 SD | Severe acute malnutrition |
| Height-for-age < −2 SD | Stunting (chronic undernutrition) |
| Weight-for-age < −2 SD | Underweight (composite index) |
| BMI-for-age > +2 SD | Overweight / obesity |
Uses
- Monitoring the growth trend — the direction of the curve matters more than a single point.
- Early detection of growth faltering and of overnutrition.
- Screening & grading of malnutrition; assessing response to treatment.
- Health & nutrition education of parents (a visual, motivating tool).
- A key tool in community programmes (Anganwadi / ICDS growth monitoring).
The direction of the curve matters more than the position.
