  • *The prevalence of insufficient physical activity among women (low income: 18.8%; 95% CI 15.9% to 21.4%; middle income: 30.1%; 95% CI 26.0% to 39.5%; high income: 41.6%; 95% CI 39.1% to 43.9%) was applied to compute the PARsemi for breast cancer and endometrial cancer.

  • †Prevalence estimates were obtained from Guthold et al. 4

  • CVD, cardiovascular disease; PAR, population attributable risk.
