    The present study was undertaken for determining the prevalence of obesity among school going adolescents and to assess the dietary intake and its adequacy and level of physical activity among adolescents. The study also aims to determine the simple screening measure for identifying adolescents with overweight and obesity. A school based cross-sectional study was done in Rudrapur city. The prevalence of overweight and obesity was found to be 10.4% and 4.1%, respectively considering IAP reference standards as cut – offs with higher prevalence among boys than girls. Result of multivariate analysis showed that type of school and mother’s educational level were the factors that were found to be significantly associated with overweight. Only type of school was found to be significantly associated with prevalence of obesity. The odd of overweight and obesity was almost 1.7 times and 2.2 times, respectively higher in private school in comparison to government school. Energy, carbohydrate, sugar and fat intake was significantly higher in obese subjects in comparison to their overweight and normal weight counterparts. On comparing the nutrient intake of subjects with the RDA suggested for Indian adolescents, the adequacy of CHO and protein intake was found in more than 80% of the subjects whereas the adequacy of ascorbic acid and magnesium intake was found in 77.7% and 67.2%, respectively of the study population. The inadequate intake of iron and zinc was found in more than 40% of the study population. More than 50% of the subjects had inadequate intake of calcium, thiamine, riboflavin and niacin. Boys were having significantly higher physical activity in comparison to girls. In comparison to active child, inactive child (>60 min/day of MVPA) had 1.5 times more chance to become overweight. Similarly, in comparison to active child, inactive child had 2.4 times more chance to become obese. ROC curve analysis was done and on the basis of Youden index (sensitivity + specificity -1), Tri ponderal mass index (TMI) was found as best screening measure for identifying overweight and obesity among adolescents. The optimal TMI cut off value for screening overweight among adolescents were >12 kg/m3 and >13 kg/m3 for boys and girls, respectively. The optimal TMI cut off value for screening obesity among adolescents were >14 kg/m3 and >16 kg/m3 for boys and girls, respectively.
