Childhood obesity is a growing global health crisis with serious implications for the well-being of children and adolescents. The rising prevalence of obesity among young people demands urgent attention and evidence-based interventions. According to the World Health Organisation (WHO), the percentage of overweight or obese children and adolescents aged 5–19 years has surged from just 4 percent in 1975 to over 18 percent in 2016.
In India, the Comprehensive National Nutrition Survey (CNNS), conducted by the Ministry of Health and Family Welfare in collaboration with UNICEF, reported that approximately 5 percent of children aged 5–9 years and 18 percent of adolescents aged 10–19 years are overweight or obese. The consequences of obesity extend far beyond appearance, significantly impacting children’s physical and mental health. Research links childhood obesity to an increased risk of chronic conditions such as type 2 diabetes, fatty liver disease, arthritis, cardiovascular disease, hypertension, and respiratory disorders, points out Dr. Anubha Shrivastava, professor and former head of the department of pediatrics at MLN Medical College, Prayagraj. Dr. Shrivastava who is also in-charge of the Pediatric Nephrology Unit and serves as the State Mentor for Newborn Services explains that obesity can lead to breathing difficulties and sleep apnea, further compromising a child’s quality of life.
Adolescents, in particular, face unique challenges associated with obesity, as they are often highly conscious of their body image. This heightened awareness can result in social withdrawal, leading to mental health concerns such as anxiety and depression. Dr. Shrivastava says that this isolation may also contribute to physical ailments like acidity. Among adolescent girls, obesity-related hormonal imbalances can cause menstrual irregularities and early or late thyroid disorders. She further highlights that obesity in adolescents generally arises from two primary causes: hormonal imbalances, also known as endocrine obesity, and poor dietary habits, which are often linked to excessive consumption of unhealthy foods. Addressing these issues requires a well-rounded approach that includes balanced nutrition, regular physical activity, and mental health support.
Beyond its health implications, obesity can take a psychological toll on children, making them more vulnerable to social stigma, discrimination, and emotional distress. Such experiences can erode self-esteem, disrupt social interactions, and hinder academic and personal development. Recognising the gravity of the issue, experts emphasise the need for early interventions to promote healthy habits from childhood. According to WHO, engaging in just 15 minutes of daily exercise can significantly help in managing obesity. Dr. Shrivastava stresses the importance of minimising junk food consumption and instead incorporating fibre-rich foods into children’s diets to support overall well-being.
Preventing and managing childhood obesity requires a multi-pronged approach that includes encouraging breastfeeding, improving access to nutritious foods, reducing the intake of sugary beverages and processed snacks, and promoting regular physical activity. Creating supportive environments that facilitate healthy choices is essential, whether through improving the nutritional quality of school meals, enhancing physical education programs, regulating the marketing of unhealthy food and drinks to children, or incorporating urban planning that encourages active lifestyles. Schools, families, and communities play a vital role in shaping children’s eating habits and exercise routines. Parents, in particular, must be mindful of their children’s dietary choices and lifestyle patterns, ensuring that they develop a positive relationship with food and physical activity from an early age.
Healthcare professionals also play a crucial role in combating childhood obesity by identifying early signs and offering timely interventions. Routine health screenings, behavioural counselling, dietary education, and family-based lifestyle programs have shown promising results in reducing obesity rates and improving children’s long-term health. These medical and psychological support systems are essential in addressing both the physical and emotional aspects of obesity.
In India, as in many other parts of the world, tackling childhood obesity requires tailored approaches that consider the country’s diverse cultural, social, and economic landscape. Collaborative efforts between government agencies, healthcare professionals, educators, policymakers, and civil society organisations are necessary to develop targeted interventions that address the root causes of obesity while promoting a culture of health and well-being among children. The battle against childhood obesity is not one that any single entity can fight alone—it requires a collective commitment to fostering healthier lifestyles and environments for the younger generation. By prioritising prevention and early intervention, societies worldwide can work towards a future where children grow up healthier, happier, and better equipped to lead fulfilling lives.
