As childhood obesity rates continue to climb in India, health experts are calling for the adoption of waist-to-hip and waist-to-height screening measures to better identify and address the growing epidemic among the nation’s youth.
Recent studies highlight that Indian children, particularly those in urban areas, are increasingly at risk of obesity-related diseases—even at lower waist circumferences compared to their counterparts in developed countries. Researchers have found that metabolic syndrome and hypertension are more prevalent among children whose waist circumference exceeds the 70th percentile, a threshold notably lower than international standards such as those used in the United States. This suggests that Indian children may be genetically predisposed to develop metabolic issues at smaller waist sizes.
Traditionally, Body Mass Index (BMI) has been the standard for assessing obesity. However, new research indicates that the waist-to-height ratio is a more accurate and cost-effective tool for detecting excess fat in children and adolescents. Unlike BMI, this ratio distinguishes between fat and muscle mass, providing a clearer picture of health risks associated with central obesity3. Experts now recommend that parents and clinicians use this measure as a simple yet effective screening method.
The urgency for improved screening comes as national surveys reveal a steady rise in overweight and obesity rates among Indian children, especially in urban centers like Delhi. Data from the Comprehensive National Nutrition Survey (CNNS) and the National Family Health Survey (NFHS) show that the prevalence of overweight and obesity increases with age, and is particularly high among children from affluent families. Factors such as sedentary lifestyles, increased consumption of energy-dense foods, and urban environmental challenges are contributing to this trend.
Pediatricians and public health advocates argue that early identification through waist-based measurements could play a pivotal role in curbing the long-term health and economic burdens of childhood obesity. They stress the need for India-specific standards and guidelines, given the unique genetic and environmental factors at play.
“Waist circumference is a good indicator for predicting health risks over BMI wherein centralised obesity is linked,” said Dr. Anuradha Khadilkar, consultant paediatrician and co-author of a major study on the topic.
