Longitudinal studies confirm that health consequences of obesity during adolescence track into adulthood and it can be reduced by successfully decreasing body fat among adolescents. Objectives: “The objectives of the study were to assess Body Mass Index of study participants and also to explore their lifestyle like physical exercise, television viewing etc.” Methodology: A cross- sectional study was conducted among randomly selected adolescent students of various secondary and higher secondary schools of Ahmedabad. A pre-tested and pre-designed questionnaire was used to assess the socio demographic variables. BMI was calculated for every student participating in the study. The analysis of data was done using Epi info version-7 software. Results: Out of 112 students participated in the study, as per the BMI 34% students were found to be obese (M=25.7% & F=45.7%) Consumption of junk foods was reported high among boys (66.4%) as compared to girls (33.4%). We found that 57.2% students were spending ? 1 hour in watching television. One third of students were not doing any kind of exercise. Conclusion: Marked gender differences were observed in relation to parameters selected for study. Females were found to be comparatively spending more leisure time watching TV/Computer, doing less exercise and having more physical complaints than there male counterpart.
