  1. Data are presented as mean (standard deviation) and p-values are adjusted for wear time, type of device, and intervention group.
  2. School = Morning bell to afternoon bell; After school = Afternoon bell to 19:00; Evening = 19:01 to 23:59.
  3. aSignificant cross-sectional difference between time periods for percentage of wear time at baseline (P < 0.05).
  4. bSignificant difference between time periods for percentage of wear time at follow-up (P < 0.05).
  5. cSignificant longitudinal difference between baseline and follow-up (P < 0.05).
