Mean (M), standard deviation (SD) and sample size (n) are given per variable at each time point.
aThe sample size for BMI was reduced at 12 years of age because measurement took place during a lab visit including an functional magnetic resonance imaging (fMRI) scan for which not all children met the inclusion criteria.
