Abbreviations: SB sedentary behaviour per 60 min/day, Total PA total physical activity per 60 min/day, MVPA moderate to vigorous PA per 60 min/day, CI confidence interval *P < 0.05, **P < 0.01, ***P < 0.001
Data were analysed with the use of 3 separate mixed models, adjusted for covariates gender, intervention group, wear time and study country; Age was centred to the lowest age of any participant (5.89 years).
