  • †Fully adjusted multilevel model including age, sex, eFSM, nuisance covariates and school effects; physical activity/fitness, internalising and externalising scores are z-scored; internalising symptoms are square-root transformed and externalising scores are rank-inverse transformed to account for positively skewed skewed distribution.

  • ‡Unadjusted multilevel models including transformed but unscaled data for PA, fitness, sex and eFSM; controlled for school effects.

  • §Reference category: not eligible for FSM.

  • ¶Reference category: male.

  • ***p<0.001; **p<0.0125.

  • eFSM, eligible for free school meals; Fit, cardiovascular fitness; PA, physical activity.
