The objective of this study was to analyze the association between being overweight and family risk factors in adolescents from Western Sao Paulo state. This cross-sectional study involved 1779 adolescents of both genders and with ages ranging between 11 and 17 years. The participants' body mass index was calculated, and the family risk factors were analyzed through a questionnaire. Excessive weight was associated with the male gender (CR=1.55 [1.22-1.97]), studying in a private school (CR=2.14 [1.56-2.94]) and mother's higher education (CR=0.52 [0.33-0.83]). There is a need to implement initiatives to fight obesity in the school environment and reach the whole family structure, taking gender-related specificities into consideration.
