BACkgROUNDS: obesity and metabolic syndrome are an increasing problem of infantile health at world level. OBJETIVE: to determine prevalence and factors associated to metabolic syndrome in obese children and adolescents in Marianao municipality. METHODS: a total of 460 students aged from 8 to 15 were evaluated. We applied a questionnaire including the following variables: age, sex, skin color, pathologic personal and family backgrounds, weight, height, blood pressure (3 takes) and waist-hip index. We performed oral glucose tolerance test (0 and 2 hrs) to measure glycemia and insulinemia, lipidogram and uric acid. Presence of metabolic syndrome was considered taking into account criteria according to Cuban proposal. We achieve distribution of qualitative and mean variable frequency, and standard deviation (SD) of the quantitative ones. We used the SPSS statistical package. RESULTS: obesity frequency was of 15 % where the 66 % presenting with severe obesity. Prevalence of metabolic syndrome among the obese ones was of 21,7 %, with a high frequency between aged 10 and 12 but no in the black people. There was a predominance of waist-hip index >90 percentile on the other criteria. Presence of metabolic syndrome and insulin-resistance increased according to severity of obesity. Personal and familiar pathologic backgrounds do not showed relation to presence of metabolic syndrome, neither with low birth weight nor with the insulin-resistance indexes. CONCLUSION: prevalence of metabolic syndrome is significant and it is associated to factors such as age, skin color and severity of obesity. Waist-hip index has a great impact on metabolic syndrome
