  2. aWe used the following thresholds for considering participants physically active in each of the physical activity indicators: total physical activity (summarizing LTPA, active commuting, and occupation activities in min/week): 150 min of moderate intensity or 75 min of vigorous intensity activities per week; LTPA: of 150 min/week of moderate intensity or 75 min/week of vigorous intensity activities; Active commuting: at least 30 min a day of walking or cycling to or from school/work)
