Independent variables are expressed as the first pivot coordinate which represents the relative contribution of one behavior relative to remaining behaviors
All regression models were adjusted for age, sex, and fat mass percentage at baseline
Bold values denote significant results
CI confidence interval, ilr1 isometric log-ratio (the first pivot coordinate), LPA light physical activity, MPA moderate physical activity, SB sedentary behavior, VPA vigorous physical activity
