  • *p<0.05, **p<0.01.

  • †The group×time interaction p value is an omnibus test assessing if there is a difference in the change from baseline between treatment groups at any follow-up time point.

  • ‡Adjusted for gender, age at baseline, BMI, education and wear time.

  • MVPA, moderate-to-vigorous physical activity.
