Evolving public health strategies to address under and over nutrition, Pg2

Key Highlights:

• A recent Vellore study tracked 251 children from urban slums from birth to nine years, revealing a sharp rise in both thinness and overweight between ages seven and nine.
• This study corroborates findings from the National Family Health Survey (NFHS)-6, which indicates India is grappling with a double burden of malnutrition.
• While NFHS-6 shows improvements in child undernutrition (stunting, wasting, underweight), it also highlights a steady increase in overweight and obesity among adults, particularly women and urban, wealthier groups.
• The Vellore study found that 45% of children were stunted at age two, with thinness affecting 26.3% and overweight/obesity 5.2% by age seven. By age nine, underweight was 21.6% and overweight/obesity rose to 14.6%.
• Maternal Body Mass Index (BMI) was identified as a predictor of childhood thinness, underscoring a trans-generational burden given that 30.7% of women aged 15-49 were overweight or obese in NFHS-6.

Detailed Insights:

• The double burden of malnutrition refers to the coexistence of both undernutrition (stunting, wasting, underweight) and overnutrition (overweight, obesity) within the same population, households, or even individuals across their lifespan.
• Traditional public health approaches in India have primarily focused on undernutrition, but recent evidence necessitates a shift to address the complexities of both forms of malnutrition simultaneously.
• The Vellore study, a collaboration between CMC-Vellore and ARUMDA at TIFR, highlights that weight-related issues in children are emerging much earlier than previously understood.
• Despite some progress in reducing child undernutrition, NFHS-6 data reveals that only 15.3% of children aged 6-23 months receive an adequate diet, indicating persistent nutritional gaps.
• The increasing prevalence of overweight and obesity contributes to a rising risk of non-communicable diseases (NCDs) like diabetes and hypertension, posing a significant public health challenge.
• Public health experts advocate for comprehensive policies that integrate both dietary interventions for undernutrition and lifestyle interventions (diet and activity) for overnutrition.
• Existing government programs like Integrated Child Development Services (ICDS) and school meal schemes, traditionally focused on undernutrition, need to be re-evaluated to also tackle poor-quality, ultra-processed, high-sugar, and high-fat diets.

Key Concepts Involved:

• Double Burden of Malnutrition: The simultaneous presence of undernutrition (stunting, wasting, underweight) and overnutrition (overweight, obesity) within a population or individual.
• National Family Health Survey (NFHS): A large-scale, multi-round survey conducted in India that provides data on health, family welfare, and other indicators.
• Body Mass Index (BMI): A measure used to assess whether a person's weight is healthy in relation to their height.
• Non-Communicable Diseases (NCDs): Chronic diseases that are not passed from person to person, such as heart disease, cancer, diabetes, and chronic respiratory diseases.
