  1. aSelection of variables in the models is based on the univariate analysis (supplement Tables 3–4) and the Akaike Information Criterion.
  2. bIncluded survey reported measure, age and age2 in the models of measured height, BMI z-score and BMI, respectively, included survey reported measure only in the model for measured weight;
  3. cInclude survey reported Height, age and age2 in the model of measured height, included survey reported weight and mother’s country of birth in the model of measured weight, included survey reported BMI z-score and household income in the model of measured BMI z-score, included survey reported BMI only in the model of measured BMI.
