For this purpose, the following interventional study was designed to investigate the effects of educational programs for students, as well as the changes in diet and physical activity on obesity and components of the metabolic syndrome. Methods: This study is part of an interventional research project (elementary school) conducted on all students of Sama schools in Zanjan and Abhar in three levels;elementary, middle and high school, including 1000 individuals in Zanjan (intervention group) and 1000 individuals (control group) in Abhar in 2011. Interventions were based on educating students, teachers and parents, changes in food services and physical activity. We primarily measured anthropometric indices, fasting blood sugar, lipid profiles and blood pressure and completed standard nutrition and physical activity questionnaires. Also, blood insulin levels were randomly measured in a number of students. Data analysis was done by SPSS software Version 16.0. Results: Overall, 589 individuals (252 males, 337 females) entered the case group and 803 individuals (344 males, 459 females) entered the control group. After two years of intervention, the mean waist circumference (63.8±10.9) and diastolic BP (63.8±10.4) were significantly lower, however, the mean systolic BP (10.1.0±12.5), food score (25.0±5.0) and drinking score (12.1±2.3) were higher in the intervention group (p<0.001). Comparing the components of metabolic syndrome between the second year and at the time of recruitment within the intervention group, showed that although the number of overweight/obese individuals, individuals with hypertriglyceridemia and high LDL increased, while those with abdominal obesity, high BP, hyperglycemia, and insulin resistance decreased (p<0.001). On the other hand, in the control group, the number of individuals with high BP increased significantly. Conclusion: The prevalence of abdominal obesity and hypertension, which are the two major components of metabolic syndrome, are much higher in our study than the other regions of the country. However, interventions for modification of diet and increasing physical activity, are effective in lowering of their prevalence. M3 10.22088/cjim.13.3.555 ER -
