  • a Observation time and accelerometer wear time were similar but not equal. The sedentary, light, and moderate-vigorous PA are percentages of accelerometer wear time, among children who were observed to have any time in that category.

  • b Total minutes include 2 minutes of a “category 7,” which were activities that were not able to be classified into the other categories.
