Study finds rising obesity alongside persistent thinness among Vellore schoolchildren

A recent longitudinal study in Vellore’s low‑income urban neighborhoods has revealed a striking “double burden” of malnutrition among children. Researchers followed 251 children from birth through primary‑school age, documenting that while stunted growth and thinness remain widespread, rates of overweight and obesity have surged dramatically between ages 7 and 9.

The study found that the prevalence of overweight and obesity nearly tripled over the two‑year period, even as thinness persisted at high levels. These findings underscore a growing public‑health paradox in India, where undernutrition and excess weight coexist in the same communities. The researchers attribute the shift to rapid dietary changes, increased access to calorie‑dense foods, and reduced physical activity as children transition into school.

The results highlight the urgent need for integrated nutrition policies that address both under‑ and over‑nutrition. Targeted interventions—such as school‑based nutrition education, improved access to healthy foods, and community exercise programs—could help reverse this trend and promote healthier growth trajectories for Vellore’s children.
