Adolescent Malnutrition in India

The NFHS-6 (2023–24) findings have highlighted a sharp rise in obesity, diabetes, and lifestyle diseases in India, emphasizing the urgent need to strengthen school-based nutrition and health interventions for adolescents.

About Adolescent Malnutrition in India

Adolescence (10–19 years) is a critical phase of physical, mental, and emotional development that requires adequate nutrition. India is currently experiencing a double burden of malnutrition, where persistent undernutrition coexists with a rapidly increasing prevalence of overweight, obesity, and lifestyle-related diseases. This dual challenge threatens not only the health of adolescents but also the country's future productivity and human capital.

Recent evidence from NFHS-6, the Comprehensive National Nutrition Survey (CNNS), and global studies shows that while stunting and anaemia continue to affect millions of adolescents, unhealthy diets, excessive consumption of ultra-processed foods (UPFs), physical inactivity, and changing lifestyles are driving an unprecedented rise in obesity and metabolic disorders.

Key Facts and Evidence

The NFHS-6 (2023–24) reveals a significant increase in obesity among Indian adults. The proportion of obese women increased from 24% to 30.7%, while obesity among men rose from 22.9% to 27.3%. Cases of high blood sugar also increased considerably, reaching 20.9% among men and 17.8% among women, indicating the growing burden of diabetes.

According to the Comprehensive National Nutrition Survey (CNNS), 2019, nearly 27.4% of Indian adolescents are stunted, while anaemia remains highly prevalent among adolescent girls. India is also witnessing the 'Thin-Fat Phenomenon', where children appear physically lean but possess excessive body fat, increasing their susceptibility to diabetes, cardiovascular diseases, and metabolic disorders.

A 2025 Lancet study projects that by 2050, nearly 21.8 crore men and 23.1 crore women in India could become overweight, with the fastest increase expected among the 15–24 years age group.

Major Causes of Adolescent Malnutrition

Nutritional Transition and Unhealthy Diet

Traditional balanced diets are increasingly being replaced by energy-dense but nutrient-poor foods. Heavy dependence on cereals, combined with inadequate intake of proteins, fruits, vegetables, and dairy products, has resulted in widespread deficiencies of essential nutrients. The Dietary Guidelines for Indians 2024 recommend that half of every meal should consist of fruits and vegetables, yet actual consumption remains significantly below recommended levels.

Growing Consumption of Ultra-Processed Foods (UPFs)

The widespread availability and aggressive marketing of High Fat, Sugar and Salt (HFSS) foods have substantially altered dietary habits among children and adolescents. According to the World Health Organization (WHO), India's consumption of Ultra-Processed Foods (UPFs) is increasing by more than 13% annually. Sugary beverages, packaged snacks, and instant foods are steadily replacing traditional nutritious diets, contributing to obesity and metabolic diseases.

Physical Inactivity and Sedentary Lifestyle

Increasing screen time, digital entertainment, and reduced outdoor activities have significantly lowered physical activity levels among adolescents. Research indicates that excessive screen exposure is associated with reduced consumption of fruits and vegetables, thereby increasing the risk of obesity and other non-communicable diseases (NCDs).

Poor Nutrition Literacy

Many adolescents lack basic knowledge regarding balanced diets, food labels, portion sizes, and misleading food advertisements. Existing nutrition education in schools often remains theoretical and fails to equip students with practical dietary skills required for healthy decision-making.

Socio-economic and Gender Factors

Poverty, food insecurity, gender discrimination, early marriage, and adolescent pregnancy continue to contribute to poor nutritional outcomes. Adolescent girls are particularly vulnerable to anaemia, which often leads to inter-generational malnutrition affecting both mothers and children.

Government Initiatives

The PM POSHAN Scheme (Mid-Day Meal Scheme) provides nutritious cooked meals to school children, aiming to improve nutrition, enrolment, attendance, and learning outcomes.

The POSHAN Abhiyaan (2018) seeks to reduce stunting, undernutrition, anaemia, and low birth weight through convergence among multiple ministries.

The Anaemia Mukt Bharat (AMB) programme focuses on reducing anaemia among children, adolescents, and women through Iron-Folic Acid supplementation, deworming, and behavioural change campaigns.

Under Ayushman Bharat, the School Health and Wellness Programme promotes nutrition awareness, healthy lifestyles, mental health, and physical fitness among school-going children.

The Eat Right India Movement, launched by FSSAI, promotes safe, healthy, and sustainable diets, while initiatives such as Eat Right Schools encourage healthier school food environments.

The ICMR-NIN's "Let's Fix Our Food (LFOF)" Initiative advocates regulating HFSS food advertising, improving food-label literacy, promoting healthy school food environments, and integrating nutrition education into school curricula.

Way Forward

Schools should be transformed into Health Promoting Institutions, where nutrition, physical activity, and healthy lifestyles become integral parts of education rather than supplementary activities.

Strict regulation is needed to establish UPF-Free School Zones by restricting the sale and marketing of HFSS foods and sugar-sweetened beverages within and around educational institutions.

Nutrition education should move beyond textbooks and teach adolescents practical skills such as reading food labels, understanding portion sizes, basic cooking, and identifying misleading advertisements.

The PM POSHAN Scheme should be further strengthened by diversifying meals with proteins, fruits, vegetables, millets, eggs, and fortified foods to ensure balanced nutrition.

Schools should ensure daily physical activity, making sports and fitness compulsory components of education to reduce sedentary behaviour and obesity.

Community participation through nutrition clubs, school gardens, fruit breaks, peer education campaigns, and behavioural change programmes can help institutionalize lifelong healthy eating habits.

Conclusion

India's adolescent nutrition challenge has evolved beyond traditional concerns of undernutrition and anaemia to include rapidly increasing obesity, diabetes, and lifestyle diseases. Since the foundations of most Non-Communicable Diseases (NCDs) are laid during adolescence, schools must become the frontline institutions for nutrition education, healthy diets, and physical activity. Investing in healthier adolescents today will significantly reduce the future burden of disease, improve workforce productivity, and contribute to achieving the vision of Viksit Bharat 2047.
