Adolescent Malnutrition in India: Emerging Nutritional Challenges and the Role of Schools in Building a Healthy Future

Recent Developments:

• The National Family Health Survey-6 (NFHS-6), 2023–24 highlights a rapid rise in obesity, high blood sugar and lifestyle-related disorders, particularly among adolescents, indicating a shift in India's nutritional profile.
• The findings reinforce the need for school-based nutrition education, regular physical activity and preventive health interventions to address both undernutrition and overnutrition.
• The Central Board of Secondary Education (CBSE) has directed affiliated schools to establish Sugar Boards to create awareness regarding hidden sugar consumption and the growing burden of childhood obesity and diabetes.

Status of Adolescent Malnutrition in India:

Double Burden of Malnutrition:

• India faces a Double Burden of Malnutrition, where persistent undernutrition coexists with rapidly increasing overweight and obesity among adolescents.
• The coexistence of nutrient deficiencies and excessive calorie consumption creates a complex public health challenge requiring integrated policy responses.
• The nutritional transition reflects changing dietary habits, urbanisation and declining physical activity across both rural and urban India.

Rising Burden of Lifestyle Diseases:

• According to NFHS-6 (2023–24), obesity has increased to 30.7% among women and 27.3% among men, while high blood sugar prevalence has risen to 17.8% among women and 20.9% among men, indicating worsening metabolic health.
• Lifestyle disorders are no longer confined to urban areas, as sedentary lifestyles, increasing stress and unhealthy dietary practices are rapidly spreading across rural regions.
• The growing prevalence of obesity during adolescence significantly increases the future risk of non-communicable diseases.

Thin-Fat Phenotype:

• Many Indian adolescents exhibit the Thin-Fat Phenotype, where individuals appear lean externally but possess excess visceral fat and poor metabolic health.
• This phenotype substantially increases susceptibility to early-onset Type-2 Diabetes Mellitus, hypertension, dyslipidaemia and cardiovascular diseases.
• The Comprehensive National Nutrition Survey (CNNS), 2019 reported that 27.4% of adolescents remain stunted, while many continue to face hidden metabolic risks despite normal body appearance.
• Nearly 35% of stunted children below five years already exhibit adult-level triglyceride concentrations, increasing their long-term risk of diabetes and cardiovascular diseases.

Poor Dietary Practices:

• Adolescent diets remain predominantly cereal-based, with inadequate intake of proteins, fruits, vegetables, pulses, milk and dairy products.
• Consumption of High Fat, Sugar and Salt (HFSS) foods and Ultra-Processed Foods (UPFs) has increased rapidly, with the UPF market growing by more than 13.7% annually.
• The Dietary Guidelines for Indians, 2024 recommend that half of every meal plate should consist of fruits and vegetables, yet actual consumption remains substantially below recommended levels.

Growing Future Burden:

• A Lancet projection (2025) estimates that by 2050, nearly 21.8 crore men and 23.1 crore women in India could become overweight or obese.
• The fastest increase is expected among the 15–24 years age group, threatening India's demographic dividend through rising healthcare costs and productivity losses.

Physical Inactivity:

• Physical inactivity has emerged as a major public health concern affecting adolescents across rural and urban areas.
• Excessive screen time, reduced outdoor activities and sedentary lifestyles contribute to obesity, unhealthy dietary habits and cardiovascular risk.
• Inadequate physical activity also adversely affects mental health, academic performance and overall physical fitness.

Major Causes of Adolescent Malnutrition:

Nutritional Transition and Food Environment:

• Rapid urbanisation, rising disposable incomes and easy availability of processed foods have accelerated unhealthy dietary transitions.
• Aggressive marketing of HFSS foods and sugar-sweetened beverages strongly influences food choices among adolescents.
• Frequent consumption of packaged snacks and fast foods displaces nutrient-rich traditional diets.

Behavioural and Social Factors:

• Limited nutrition literacy reduces adolescents' ability to make informed dietary decisions.
• Peer influence, digital advertising and social media marketing encourage unhealthy food consumption.
• Parental food choices and household purchasing behaviour significantly shape children's eating habits.

Role of Schools in Addressing Adolescent Malnutrition:

Nutrition Literacy and Skill-Based Learning:

• Schools should equip students with practical nutrition skills, including food label reading, portion control and identification of misleading food advertisements.
• The Indian Council of Medical Research–National Institute of Nutrition leads the Let's Fix Our Food (LFOF) Consortium, which promotes healthier food environments through nutrition literacy and food-label education.
• CBSE's Sugar Board initiative helps students understand the hidden sugar content of packaged foods and beverages while promoting informed food choices.
• The NCERT–UNESCO "Let's Move Forward" comic can strengthen awareness regarding balanced diets, hidden sugars and healthy lifestyles.

Healthy School Food Environment:

• Schools should establish HFSS-free and UPF-free campuses by implementing the Food Safety and Standards Authority of India (FSSAI) Eat Right School Initiative.
• Healthy canteen policies should prioritise nutritious, safe and balanced food options through curricular and co-curricular activities.
• FSSAI regulations prohibit the sale of HFSS foods within 50 metres of school campuses, reducing children's exposure to unhealthy foods.
• PM POSHAN should promote balanced meals incorporating proteins, millets, pulses and locally available nutritious foods.
• School nutrition gardens, fruit breaks and seasonal produce consumption can strengthen healthy eating behaviour from an early age.

Curriculum Reforms and Physical Activity:

• Nutrition education should move beyond theoretical concepts and develop lifelong healthy eating practices.
• Knowledge of macronutrients, micronutrients and balanced diets should become a core life skill.
• Daily physical education, sports and structured exercise should form an essential component of the school curriculum rather than remaining optional activities.
• Regular physical activity reduces obesity, improves cardiovascular health, strengthens mental well-being and enhances academic performance.

Institutionalising Periodic Health Screening:

• Schools should integrate health monitoring with the Rashtriya Bal Swasthya Karyakram (RBSK).
• Periodic Adolescent Health and Wellness Days should facilitate screening for Body Mass Index (BMI), anaemia and early metabolic disorders.
• Early identification and timely referral to Primary Health Centres (PHCs) can prevent progression of chronic diseases.

Community and Parental Participation:

• Parents should receive regular awareness regarding dietary diversity, healthy cooking practices and the risks associated with UPFs and HFSS foods.
• School-based behavioural interventions become more effective when reinforced through healthy household food environments.
• Community participation strengthens long-term adoption of healthy lifestyles among adolescents.

Policy and Regulatory Measures:

• Higher taxation on sugar-sweetened beverages can discourage excessive consumption.
• Strict regulation of surrogate advertising and marketing of unhealthy foods targeting children should be strengthened.
• Front-of-Pack Labelling (FoPL) can enable consumers to make healthier food choices through simplified nutrition information.
• Inter-sectoral coordination among health, education, food safety and local governance institutions is essential for sustained nutritional improvement.

Government Initiatives Related to Adolescent Nutrition:

Major Schemes and Programmes:

• PM POSHAN provides nutritious cooked meals to improve child nutrition and learning outcomes.
• POSHAN Abhiyaan promotes convergence-based action against malnutrition across different age groups.
• Rashtriya Bal Swasthya Karyakram (RBSK) provides early screening and intervention for childhood diseases and nutritional disorders.
• Eat Right School Initiative promotes healthy food environments and nutrition awareness in schools.
• School Health and Wellness Programme under Ayushman Bharat encourages preventive healthcare, mental well-being and healthy lifestyles among school children.

Challenges in Addressing Adolescent Malnutrition:

Key Constraints:

• Poor implementation of school nutrition regulations limits the effectiveness of existing policies.
• Limited nutrition awareness among families reduces adoption of healthy dietary practices.
• Inadequate physical education infrastructure and trained instructors constrain regular physical activity.
• Increasing affordability and accessibility of processed foods continue to undermine healthy food choices.
• Socio-economic inequalities restrict access to balanced diets among vulnerable populations.

Conclusion:

Way Forward:

• Schools should evolve from centres of academic learning into institutions promoting preventive healthcare and lifelong healthy behaviours.
• Nutrition literacy, healthy food environments, compulsory physical activity and periodic health screening should become integral components of school education.
• A coordinated approach involving families, schools, healthcare institutions and government agencies is essential for reducing adolescent malnutrition and preventing future lifestyle diseases.
• Strengthening adolescent nutrition today will improve human capital, enhance productivity and ensure that India's demographic dividend translates into sustainable national development.
