  1. a Overweight at baseline defined as a BMI equal to or greater than international age- and sex-specific cutpoints for overweight; overweight at follow-up defined as a BMI≥25 kg/m2.
  2. b PR: prevalence ratios adjusted for the effects of clustering by school.
  3. c PR: prevalence ratios adjusted for the effects of clustering by school plus baseline area-level SES, baseline smoking, baseline parental physical activity; follow-up associations also adjusted for highest level of education, smoking at follow-up, marital status at follow-up and number of live births at follow-up (females only).
