Prevalence of coronary artery calcification in the general population. Studies reporting coronary artery calcification (CAC) prevalence and adjusted odds ratios for the association between physical activity and CAC are shown.20,22,27,30 A, Percentage of CAC prevalence (CAC Score [CACS]>0) across physical activity/exercise groups. B, Adjusted odds ratios for CAC prevalence across physical activity/exercise groups. In B, Desai et al (blue color) included 520 men and 259 women, but the sample size per physical activity categories was not reported. In summary, there is no clear net effect toward either a positive or inverse association between physical activity volumes and CAC prevalence in general population studies. MET indicates metabolic equivalent of task; and PA, physical activity.
