  1. ST sedentary time; LPA light physical activity; MVPA moderate-to-vigorous physical activity
  2. β1 (SE), ilr1 (….): first isometric log-ratio regression coefficients from regression models represents one activity behaviour relative to all remaining behaviours (standard error in parentheses). Bolded coefficients indicate those significantly associated with the outcomes at p < 0.05
