NEET PG High-Yield: Public Health Undernutrition
Undernutrition encompasses a spectrum of deficiencies. In public health, the focus remains on indices for assessment and the clinical classification of severe acute malnutrition (SAM).
Assessment & Classification
| Indicator | NEET PG Context |
|---|---|
| Stunting | Low height-for-age (Chronic malnutrition). |
| Wasting | Low weight-for-height (Acute malnutrition). |
| Underweight | Low weight-for-age (Composite of stunting and wasting). |
| SAM Criteria | MUAC < 11.5 cm, Weight-for-height < -3 SD, or presence of bilateral pitting edema. |
High-Yield NEET PG Pearls:
- Gomez Classification: Based on weight-for-age.
- Waterlow Classification: Based on stunting and wasting.
- Wellcome Classification: Based on weight-for-age and presence/absence of edema.
- The “Hidden Hunger” Refers to micronutrient deficiencies (Iron, Vitamin A, Iodine, Zinc) that can coexist with protein-energy malnutrition.
