1 Beta values reflect differences in minutes of ST/LPA/MVPA for every 1 measured unit of each predictor variable. 2 NE = not entered in final model. 3 Reference group for weight status was normal weight. ST, sedentary time; LPA, light physical activity; MVPA, moderate to vigorous physical activity; ICC, intraclass correlation coefficient. † p < 0.05, †† p < 0.01, ‡ p < 0.001.
