Obesity among pre-adolescent and adolescents of a developing country (India).
There are very few reports from the developing world on the prevalence of obesity among children even though in developed countries it has reached epidemic proportions. The objective of this study was to determine the prevalence of obesity in pre-adolescent and adolescent children in a developing country (India) using WHO guidelines for defining obesity and overweight. This cross-sectional study was carried out on 2008 school-children aged 9-15 years. Approximately half the subjects belonged to a school attended by children of well to do families while the rest belonged to two schools from middle and lower socio-economic background. Weight and height were taken for all children and the body mass index (BMI) calculated. Children whose BMI was >85th percentile for age and sex were defined as overweight. Triceps skin fold thickness (TSFT) was measured for all overweight children and those with TSFT >90th percentile for age and sex were defined as obese. The overall prevalence of obesity and overweight was 11.1% and 14.2% respectively. The prevalence of obesity as well as overweight was higher in boys as compared to girls (12.4% vs 9.9%, 15.7% vs 12.9%). Prevalence of obesity decreased significantly with age, from 18.5% at 9 years to 7.6% at 14 years, rising at 15 years to 12.1%. Significantly more children from higher socio-economic status were obese and overweight than those from lower socio-economic status groups. No significant gender difference for obesity prevalence was seen among children from a less privileged background, however, amongst children from affluent families, significantly more boys were obese as compared to girls. Pediatric obesity is an emerging problem in developing countries, especially among higher socio-economic status groups. Significant gender disparity is seen, with boys of affluent background having a higher prevalence.
