  • *Regression coefficients are unstandardised.

  • †Male sex was used as a reference category, and given a value of zero, against which the effects of the female sex category were assessed. Sample sizes for the unadjusted analyses ranged from 968 to 1016, and for the adjusted analysis was 911. All analyses adjusted for clustering at the school level.

  • CPM, counts per minute; IMD, Indices of Multiple Deprivation; PA, physical activity.
