Nutritional problems in public health- Undernutrition

 

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.
