  1. Values are presented as OR and 95%CI. **P < 0.001, *P < 0.05.
  2. Multivariate logistic regression model was applied with adjustment for gender, age, area, physical activity, family history of obesity, paternal and maternal educational level and family monthly income (all variables stratified by sex were not adjusted for gender).
