⁽¹⁾The effect of each predictor on the offspring BMI status was separately evaluated; ⁽²⁾Includes all predictors (i.e. maternal age at pregnancy, gestational weight gain, exercise levels, alcohol consumption and smoking on obesity status); ⁽³⁾Includes all predictors entered in the full model plus, birth weight, maternal weight status pre-pregnancy and history of breastfeeding, as potential confounders.
