  • ORs reflect the likelihood of regular participation in each activity per 1 SD increase in cognition score. For sport and active games, reading for enjoyment, gaming on PC/games console, this reflects participation on most days. For online messaging, this reflects participation at least once a month.

  • Model 1 included only one cognitive measure as an exposure per regression and adjusted for age, maternal smoking status during pregnancy, income, maternal qualifications, ethnicity and strengths and difficulties score.

  • Model 2 adjusted for variables in model 1 and included all cognitive scores at ages 3–11 as exposure measures.

  • *Significant sex interaction detected (P<0.05).

  • PC, personal computer.
