  1. Data are shown as estimated mean with 95% confidence intervals of changes in obesity outcome. Maintained inactive group, n = 2129; switching from active or public transportation commuting to inactive group, n = 328; switching from inactive to active or public transportation commuting group, n = 322; maintained active or public transportation commuting group, n = 1532
  2. aModel 1: Adjusted for age and sex at baseline. In addition, baseline variables of each outcome, treated as continuous data, were adjusted for (e.g., baseline waist circumference when outcome is changes in waist circumference)
  3. bModel 2: Further adjusted for other variables
