  1. Model 1: coefficients were estimated with linear-mixed models with random intercept, with adjustment for age
  2. Model 4: adjusted for age, ethnicity, current smoking, current alcohol consumption, special diets, weight gain anxiety, and physical activity, maternal overweight, paternal overweight, parental care, and parental control, family affluence and racism
