Standing	0 (1; 0–35)	0 (1; 0–28)

Type of activities are presented as % of wear time (median, interquartile range and minimum-maximum)
^aWear time is total wear time in hours, presented as mean (standard deviation)
^bTime spent physically active = total duration of walking, running, non-cyclic movement, wheeling and (hand)biking, presented as a % of wear time
^cTime spent sedentary = total duration of sitting and lying, presented as a % of wear time
^dDifferences between a school day and weekend day for wear time was tested with the paired samples t-test. Differences between a school day and weekend day for time spent physically active and time spent sedentary were tested with the Wilcoxon Signed Rank test
