^aIn these two-level logistic regression models, the repeated PA level measure (level-1) were nested within each individual (level-2)

^bDependent variables are if the individual did PA (level-0 vs all others) in model 1, if the individual had regular or irregular activity (level-1 vs level-2 and 3) in model 2, or if the individual had low-level or moderate activity (level-2 vs level-3) in model 3

^cn = 3057 individuals with N = 11,742 observations in total were used

^d*p < 0.05, **p < 0.01, ***p < 0.001
