a: insufficient variation to calculate daily mean minutes. Gender differences were analyzed using multi-level linear mixed models adjusted for gender, age, number of days with valid PA measurement, and clustering of days within children and children within schools. b: significantly higher for boys compared to girls. b: significantly higher for girls compared to boys
