Decomposition of the effect of physical activity level (low vs. high) on the incidence of all-cause mortality, fatal cardiovascular disease (CVD), and nonfatal CVD events via diabetes, by sex, Sacramento Area Latino Study on Aging, 1998–2007. A) men; B) women. Hazard ratios (HRs) were adjusted for age, sex, educational level, country of birth, marital status, acculturation, smoking, alcohol intake, activities of daily living, instrumental activities of daily living, current employment status, and type of occupation. We performed 10,000 iterations for bootstrapping to estimate 95% confidence intervals (CIs) for the total effect and the indirect effect (through diabetes). The x-axis is shown on the log scale. The percent mediated was calculated as log(indirect effect)/log(total effect).
