  • *Strength of evidence as reported by the 2018 Physical Activity Guidelines Advisory Committee.

  • †Estimated from weekday and weekend proportions available from Health Survey for England5 and multiplied by the prevalence adjustment factor for each outcome.

  • RR, relative risk;PAF, population attributable fraction.
