The Lingering Shadow of Undernutrition
For decades, India's primary public health battle was against undernutrition. Despite significant economic growth, this challenge persists. According to the latest National Family Health Survey (NFHS-6), conducted in 2023-24, nearly three in ten children
under five are stunted, a sign of chronic undernutrition that can impair cognitive development. The data also highlights that wasting, an indicator of acute malnutrition, continues to affect a significant number of children. While there has been progress, with stunting rates declining from 35.5% in the previous survey, the absolute numbers remain enormous due to India's large population. This problem is not just about a lack of calories; it points to deeper issues of poverty, inadequate maternal nutrition, poor sanitation, and unequal access to quality healthcare.
The Rapid Rise of a New Epidemic
At the same time, a different kind of malnutrition is taking hold: overnutrition. The same NFHS-6 survey reveals a steep climb in the prevalence of overweight and obese individuals. Among women aged 15-49, the share classified as overweight or obese jumped from 24% to nearly 31%. Men have seen a similar increase, rising from about 23% to 27%. This trend isn't confined to wealthy, urban centres. While cities show higher rates, the increase in overweight and obesity is happening rapidly in rural areas as well. This surge is linked to a rise in non-communicable diseases like diabetes and hypertension, creating a new and costly public health crisis for the nation to manage.
Explaining the 'Double Burden'
This coexistence of undernutrition and overnutrition is known as the “double burden of malnutrition.” It’s a phenomenon seen in many developing countries undergoing rapid economic and social change. The primary driver is a “nutrition transition.” As incomes rise and more people move to cities, traditional, fibre-rich diets are often replaced. There is greater access to and consumption of processed foods, which are often high in calories, sugar, salt, and unhealthy fats but low in essential nutrients. Simultaneously, lifestyles are becoming more sedentary, with less physical labour and more screen time, leading to a mismatch between energy intake and expenditure. This transition happens unevenly. In the same community, or even the same household, it’s possible to find a stunted child and an overweight adult, reflecting a complex mix of food insecurity and changing dietary patterns.
A Tale of Two Indias
The double burden doesn't affect everyone equally. Undernutrition remains disproportionately high among the rural poor and in certain states. Meanwhile, obesity, while growing everywhere, is still more prevalent in urban areas and among wealthier populations. However, these lines are blurring. Studies show the fastest rate of increase in overnutrition is now among rural communities, as processed foods become more accessible and aspirations change. This creates a complex policy challenge. The interventions needed to fight stunting in a remote village are very different from those required to curb rising obesity in a bustling city or a transitioning town. It’s no longer a single problem but a spectrum of nutritional imbalances that vary by geography, gender, and economic status.
Navigating a Complex Future
Tackling India’s dual nutrition problem requires a sophisticated, two-pronged approach. Policies cannot focus only on providing enough calories to fight hunger; they must also promote the consumption of nutritious, healthy food. This means improving food environments to make healthy options more affordable and accessible than their processed counterparts. It involves public health campaigns that raise awareness about healthy diets and the risks of sedentary lifestyles. For undernutrition, strengthening maternal and child health programs, promoting diverse diets, and improving sanitation remain critical. For overnutrition, strategies may include better food labelling, restrictions on marketing unhealthy foods to children, and creating more public spaces for physical activity. The goal is to ensure that as India develops, its growth translates into better health for all its citizens, not just a shift from one form of malnutrition to another.
