Descriptive information and accelerometer wear time, by age group.

1 BMI percentiles; computed as recommended by the Centers for Disease Control and Prevention 2 Average time (in minutes) per week day that participants wore the accelerometer 3 Average time (in minutes) per weekend day that participants wore the accelerometer 4 Average total duration of week day in minutes; note that only data from specific windows of activity during the day were used for analysis; also note that schedules were not similar among participants therefore the total duration expected varied to some degree. 5 Total duration of weekend day in minutes; this value was equal to 900 minutes and didn’t have any variability since weekend days were set for 15 hours duration (7:00AM to 10:00PM) and equal among all participants.
