  1. aUnadjusted model. Not adjusted for covariates
  2. bPartially adjusted model. Adjusted for participant characteristics only (sex, age, race, maturity offset, chronic medical conditions, body mass index)
  3. cFully adjusted model. Adjusted for participant characteristics (sex, age, race, maturity, chronic medical conditions, body mass index), family characteristics (family income, number of parents in household), neighborhood environment characteristics (green space, traffic volume), and characteristics of the day sleep and outdoor active play were measured (weekday/weekend/holiday, daylight hours, time spent in other types of physical activity, accelerometer and GPS watch wear time)
