OBJECTIVE: to analyze associations between overweight and family risk factors in different school environments. METHODS: a descriptive/analytical cross-sectional study of 1779 adolescents (aged between 11 and 17 years) of both sexes in the public (n=1309) and private (n=470) education systems. Family factors evaluated included: sex, economic circumstances, number of siblings, number of televisions and level of schooling of parents. The prevalence ratio (PR) in a univariate and multivariate model suggested the scale of the associations under study. RESULTS: in private schools, overweight was associated with the level of schooling of the father (RP= 0.68 [0.5-0.9]) and with boys (RP= 1.38 [1.0-1.8]). In public schools it was associated with the level of schooling of the mother (RP= 1.42 [1.1-1.8]), having fewer siblings (RP= 1.23 [0.9-1.5]) and with boys (RP= 1.32 [1.6-1.6]). CONCLUSIONS: overweight is associated with different family factors depending on the kind of school.
