The present studywas carried out to assess the effectofimplementation ofhealth promotion program in school on control of risk factor for obesity in obese adolescents and those at risk of obesity. Methods: This quasi-experimental study was carried out involving two groups (case and control) in 1385 in Tehran. Two boysʹ secondary schools were selected randomly from secondary schools ofʹoth region of Education Ministry in Tehran. Body weight and height of the students were measured and body mass indexes (BMl) "ere calculated. They were divided intotwo case and controlgroups.each containing35 students. The case group consistedoverweightand at risk for overweight studentʹ (Overweight and at risk tor overweight were defined as > 851hand > 95th percentile of age-sex-specific CDC 2000 BMI values, respectively). The tools tor data collection included electronic scale, stadiometer, demographic questionnaires of adolescents and parents, Food Frequency Questionnaire (FFQ), nutritional knowledge and a questionnaire for recording physical activityand watchingTV in one week.They were distributed to be filled out by students before and one month after the intervention. The intervcntional program was done in four months included separate educational sessions for teachers, parents and adolescents and changes in school environment. Results: There was no significant differences between the adolescentsʹ mean Body Mass Index (BM!) in two group after intervention (P>O.05). There was a significant difference between mean nutritional knowledge score in the case group before and after the intervention (P~.OOI5). We found significant differences between the mean of intake of dairy products, salty snack, sweets, carbonated beverages and fast food in the case group after and before the intervention (P~.OOI, ~.006, P~.034, ~.OOI; respectively), but there was 110 significant difference between the intake mean of these food products in the control group after and before the intervention (P>O.05). There were significant differences betweenthe mean time of vigorous physicalactivityinone week and TV watching in the case group after and before the intervention (M.04, ~.OOI respectively) whereas there is 110significant differences between mean time ofthese activities in control group (P>O.05). Conclusion: This research showed that although there were no significant differences between the studentsʹ mean BM! between the two groups after intervention but implementation of this prograrr to control risk factors for obesity regarding dietary pattern and physical activity "as successful. Therefore, it is recommended to investigate the effectiveness of such interventions overtimein further studies.
