Children who did not participate in a specific context did not contribute to the calculation of the median minutes. Bold categories highlight the focus of subsequent analyses. 1 Contextual domain based on the accumulation of GPS points falling within a 10 m buffer surrounding the polygon parcel(s). ‡ Contextual domain based on the accumulation of GPS points certifying a certain speed threshold. * Afterschool PA and GPS data that remained after the excluding all categories above. Gender differences were investigated using log-transformed multilevel linear mixed models, adjusting for context-specific wear time, age, meteorology, social economic status of the neighborhood, and nested structure of days within children and children within schools. 1 Mean significantly lower for boys vs. girls. 2 Mean significantly higher for boys vs. girls.
