We read the article by Ghosh et al., "correlates of overweight and obesity among urban adolescents in Bihar, India" with interest.  The authors have done a commendable job of highlighting an issue of public health importance in adolescents of Bihar. However, some issues need to be addressed.
First, the reference for sample size calculation (prevalence = 20%) is a review article which quotes overweight and obesity in Indian studies ranging from 4.7% to 29%.  An original and nationally representative study or a meta-analysis is preferable in calculating a sample size.  Moreover, authors mention the lack of data regarding overweight/obesity in National Family Health Survey (NFHS). It is important to point out that NFHS-3 does report overweight and obesity in the age group of 15-19 years which is 3.5% at national level. For Bihar, it is 1.3% in females and 0.7% in males of 15-19 years of age. 
Authors have used reference data from the Center for Disease Control and Prevention 2000 dataset for body mass index cut-offs. It would have been preferable to use standardized World Health Organization cut-offs for the age group of 5-19 years which are applicable for developed as well as developing countries.  Moreover, the population is classified in dichotomous categories (overweight and not-overweight) which groups together participants who are normal and thin. According to NFHS-3, the age group of 15-19 has the highest prevalence of thinness, 52% in females and 61.6% in males in this age group in Bihar.  It will be interesting to see the burden of thinness in the 79% reported as not overweight in this study (where participants of 15 years of age are in majority). In addition, the methodology used for the determination of socio-economic status is unclear, and physical activity due to household chores remains undocumented (which is significant in India).
Finally, the analysis shows a significant association between nonconsumption of vegetables and fruits with overweight/obesity. However, socio-economic status is an important confounder in case of intake of vegetables and fruits.
