AbstractLittle evidence exists regarding the sex-specific population attributable risk factors for cardiovascular and all-cause mortality in the Chinese general population. We used a sub-cohort of the China Patient-Centered Evaluative Assessment of Cardiac Events million persons project to evaluate the overall and sex-specific associations and population attributable fractions (PAFs) of twelve risk factors for cardiovascular and all-cause mortality. 95,469 participants were included between January 2016 and December 2020. The twelve risk factors (including four socioeconomic status and eight modifiable risk factors) were collected or measured at baseline. The outcomes of the study were all-cause mortality and cardiovascular mortality. Overall, 60.7% (N = 57,971) were women, and the mean age was 54.3 ± 10.2 years. After a median of 3.52 years of follow-up, 1311 (1.4%) people died, and 362 (0.4%) people died of cardiovascular causes. Majorities of risk factors were significantly associated with all-cause and cardiovascular mortality, and suboptimal blood pressure and low educational attainment were the two leading attributable risk factors for all-cause and cardiovascular mortality. The twelve risk factors collectively explained 72.4% (95% confidence interval (CI): 63.5, 79.2) and 84.0% (95% CI: 71.1, 91.1) of PAFs for all-cause and cardiovascular mortality. When stratified by sex, men had more risk factors that were significantly attributable to mortality than women, whereas low educational attainment had a more pronounced impact on female cardiovascular health. This study found that the twelve risk factors collectively explained a significant proportion of PAFs for all-cause and cardiovascular mortality. Several sex-related disparities in the associations between risk factors and mortality were noted.Copyright © 2023. Published by Elsevier Inc.
