BMI – body mass index, MVPA – moderate-to-vigorous physical activity, ST – screen time, SL – sleep
^aBased on the BMI z-score
^bAdjusted to 24 h
^cThe differences between age categories were analyzed with the independent t-test for continuous variables and the chi-square test for categorical variables
