  1. BMI Body mass index, CI Confidence interval, ilr1 Isometric log-ratio (first coordinate), LPA Light intensity physical activity, MVPA Moderate-to-vigorous physical activity, SB Sedentary behavior
  2. All dependent variables were transformed before analysis using the natural logarithm
  3. Independent variables are expressed as the first pivot coordinate which represents the relative contribution of one behavior relative to remaining behaviors
  4. All models were adjusted for sex and age
  5. Bold values denote significant chance in adiposity status
