Notes. SD = Standard Deviation, iPA = Increasing physical activity, iSED = intervention to reduce sedentary behavior, LIPA = light physical activity, MPA = moderate physical activity, VPA = vigorous physical activity, VVPA = very vigorous physical activity. a There are 6 missing values for education level, 5 for job demands, 14 for job control, 8 for social support.
