Double burden of underweight and overweight among children (10–19 years of age) of employees working in Indian industrial units

Abstract

Background. Along with the existing problem of underweight, overweight in children is increasing in the developing world. However, there is little information on its magnitude and pattern in the Indian context. We aimed to study the pattern and correlates of overweight in Indian children and adolescents. Methods. A total of 3750 children in the age group of 10–19 years, who were family members of randomly selected employees from 10 different industrial sites in India, were surveyed using an interviewer-administered questionnaire. Results. The prevalence of underweight was highest in peri-urban areas (30.2% and 53.2% according to Indian and international criteria, respectively). In urban and highly urban areas, the prevalence of underweight was 14.1% and 9.8%, respectively, according to the Indian criteria, and 27.1% and 19.2%, respectively, according to international criteria. The proportion of overweight children was highest in the highly urban category (19.1% and 13.4% according to Indian and international criteria, respectively). The level of urbanization (OR 3.1 and 4.7 for overweight in urban and highly urban areas, respectively, compared with peri-urban areas, p<0.001), physical activity (OR 0.4, p<0.001, in children with physical activity score >75th percentile compared with a score <75th percentile) and frequency of meals outside the home (OR 12, p<0.001, if >25% weekly meals taken outside the home compared with <25% of weekly meals outside home) were significant predictors of overweight. Conclusion. There is a double burden of underweight and overweight among Indian children and adolescents.
