  • Tables include standardised β coefficients and 95% CIs for physical activity variables predicting academic attainment. Minimally adjusted model (model 1) adjusts for cpm and age of participants; fully adjusted model (model 5) adjusted for cpm and age plus birthweight, gestation, age of mother at delivery, mother's oily fish intake, whether the mother of participants smoked in the first 3 months of pregnancy, BMI Z score relative to UK 1990 reference data, pubertal stage of participant (recorded at time of outcome) ethnicity, maternal educational attainment and occupational social class. Coefficients for each stage of adjustment and for cpm as a predictor are shown in online supplementary material. At age 16, correction for the effects of regression dilution using ICC increased coefficients from 0.11 to 0.25 for females for English GCSE attainment. For Maths, the coefficient increased to 0.18 and for Science increased to 0.32.
