  1. The cut-off points of the tertiles were 28.8 and 41.1 min · d−1 for girls and 39.8 and 51 min · d−1 for boys
  2. N number of participants, SD standard deviation, MVPA moderate-to-vigorous physical activity, P MVPA P-value for one-way analysis of variance, P trend P-value for linearity test
  3. *Significantly different from the third tertile, Fisher’s LSD post-hoc test after one-way analysis of variance, P < 0.05
  4. aValues were transformed to natural logarithms before analysis
