Abbreviations: PAEE- physical activity energy expenditure, MVPA- moderate-to-vigorous physical activity; Data are median (IQR); MVPA was defined as intensity >3 MET, light-intensity PA as intensity between 1.5-3.0 MET and sedentary behaviour as intensity <1.5 MET; Total N varies due to variation in the amount of missing data for different covariates; *p < 0.1 for interaction by sex.
