The model was adjusted for age of the child, BMI z-score, sex, family type, highest completed household education, equalized household income, immigration status and presence of psychiatric diagnoses for the child and parents. Difference in BMI z-score per years is stratified as (a) all available observations through follow-up, (b) observation between inclusion to 6 months, (c) observations between 6 months and 1 year, (d) observations between 1 year and 3 years and (e) observations between 3 and 10 years.
