New Delhi, Mar 30: The growing dependence on smartphones among children is emerging as a key factor behind a silent surge in childhood obesity across India, with doctors warning that the trend is far more serious than many families realise.

Health experts say the practice of using mobile phones as a distraction during meals is leading to unhealthy eating habits, reduced physical activity and long-term metabolic risks. According to Dr Vijay Yewale, even children as young as five are showing signs of weight gain due to excessive screen exposure and poor dietary patterns.

A recent study conducted in Gujarat found that 43 per cent of children with more than four hours of daily screen time were either overweight or obese, often resorting to high-sugar and high-fat snacks due to boredom and stress. Doctors identify children aged 8 to 14 as the most vulnerable group.

Medical professionals note that parents often overlook early signs of obesity until complications arise. Dr Vimal Pahuja cited a case of a 12-year-old who developed fatty liver, insulin resistance and vitamin deficiencies after prolonged gaming and junk food consumption. Lifestyle changes, including reduced screen time and increased physical activity, helped reverse some of the damage.

Experts say screen addiction is reshaping children’s relationship with food. Dr Asmita Mahajan pointed out that excessive screen use reduces outdoor play and encourages sedentary habits, while nutritionist Sangeetha Aiyer noted that distracted eating prevents children from recognising hunger and fullness cues.

Research also shows that prolonged screen exposure disrupts sleep patterns and hormonal balance. Blue light from devices affects melatonin levels, which in turn impacts appetite-regulating hormones like ghrelin and leptin, increasing cravings for sugary foods and late-night eating.

Studies published in journals such as JAMA Pediatrics have linked excessive screen time to higher risks of obesity, high blood pressure and abnormal cholesterol levels in children. If left unchecked, experts warn, it could lead to serious conditions including Type 2 diabetes, heart disease and metabolic disorders later in life.

Nutritionists also highlight the “double reward” effect, where screen use combined with junk food consumption reinforces unhealthy habits through dopamine-driven behaviour, making such patterns difficult to break.

Psychologists stress that addressing the issue requires parental involvement. Dr Dipti Yadav said children tend to imitate adults, and reducing screen dependence must begin with parents setting healthier examples, encouraging outdoor activities, hobbies and screen-free family time.

Experts emphasise that early intervention, balanced routines and mindful eating habits are crucial to prevent long-term health consequences among children.
