  1. aAdjusted for accelerometer wear time, baseline MVPA, sex, baseline BMI, baseline SES and change in daylight from baseline to follow-up
  2. bBeta values: impact of baseline sleep, screen time, active transport and sports/exercise on change in MVPA from baseline to follow-up
  3. b (95% CI), beta coefficient (95% confidence interval); min/d, minutes per day; ref., reference group; MVPA, moderate-to-vigorous physical activity; hrs/week, hours per week
