  1. Data within person was collapsed to average values across days before analysis. Moderate and vigorous physical activity were transformed using natural log as these variables were skewed before analysis; presented values have been exponentiated back to the original scale. 1Gender comparisons made by linear regression accounting for within-school clustering; 2Gender comparison made by chi-square test.
