  • 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.

  • *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.

  • IMD, Indices of Multiple Deprivation; PA, physical activity.
