New Delhi, Aug 11: Childhood obesity is emerging as a serious health concern worldwide, with millions of children affected each year. Defined by a child’s weight being higher than healthy for their age and height, obesity in early life not only increases risks of diabetes and heart disease but is now linked to colorectal cancer in adulthood.

Medical experts explain that obesity in childhood causes lasting damage, including inflammation and changes in gut health, which may trigger cancer development later. Parents hold a crucial role in prevention through healthy diets, active lifestyles, and limiting unhealthy food and screen time.

Unlike adults, children’s weight status is assessed against age- and sex-specific growth charts. Severe obesity in children falls into two categories: Class 2 (BMI 120-140% of the 95th percentile) and Class 3 (above 140%), both associated with heightened health risks.

The causes of childhood obesity are multifaceted — genetics, poor diet with high-calorie processed foods, and sedentary habits fueled by excessive screen time contribute heavily. Notably, additives in many snacks linked to cancer have been banned recently in some regions.

A large US study involving over 4.7 million participants found boys obese in childhood had a 39% higher risk of colorectal cancer as adults, while girls had a 19% increased risk, highlighting the urgent need for early interventions.

Experts urge parents to promote balanced meals rich in fruits, vegetables, whole grains, and lean proteins, encourage at least 60 minutes of daily physical activity, reduce processed foods and sugary drinks, and set screen time limits.

Early awareness and lifestyle changes can drastically reduce future health risks. Schools, healthcare providers, and communities are also called upon to support healthier habits among children.

Childhood obesity is more than a temporary issue; it is a long-term threat to health that can be managed with timely action and care.
