*Represents statistically significant P values that are < 0.05
Values are mean (SD); Moderate-to-vigorous physical activity (MVPA)
1P values from non-normally distributed variables are from non-parametric, two-sample, Wilcoxon-Mann-Whitney rank-sum tests of the null hypothesis that the distribution of girls is equal to the distribution of boys. P values from normally distributed variables are from two-sample t-tests of the equality of means
