Background: To assess the association between health-related quality of life (HRQL) and a composite outcome including incident coronary heart disease (CHD) and cerebrovascular events in a large general population-based cohort. Design: Prospective analysis on 17,102 men and women (mean age 53 Â± 11) free from cardiovascular disease at time of enrolment in the Moli-sani cohort (2005â 2010). Methods: HRQL was assessed by the 36-Item Short Form Health Survey. Hazard ratios with 95% confidence intervals (95% CIs) were calculated using multivariable Cox-proportional hazard models. Results: At the end of follow-up (median 4.2 years), 237 new events occurred (coronary heart disease n = 197, cerebrovascular disease n = 42). In a multivariable model adjusted for socioeconomic factors, chronic disease and health-related behaviours, both mental and physical HRQL were inversely associated with the risk of the composite outcome (hazard ratio = 0.57; 0.39â 0.84 and hazard ratio = 0.62; 0.40â 0.94, respectively; highest vs. lowest quartile). Further adjustment for C-reactive protein marginally modified the association with physical HRQL (hazard ratio = 0.67; 0.43â 1.02). Similar findings were obtained when only CHD events were analysed (hazard ratio = 0.63; 0.41â 0.96 for highest versus lowest mental HRQL) although results with physical HRQL were no longer significant (hazard ratio = 0.65; 0.40â 1.04 for highest versus lowest quartile). Associations with incident cerebrovascular disease showed a trend toward protection (hazard ratio = 0.50; 0.22â 1.17 and hazard ratio = 0.51; 0.22â 1.23 for highest versus lowest tertile of mental and physical HRQL, respectively). Conclusions: HRQL is an independent predictor of composite CHD/cerebrovascular outcomes in an adult population. The magnitude of the association was not affected either by socioeconomic factors, health conditions or health-related behaviours. Improvement of quality of life may be a major factor in targeting appropriate prevention strategies for cardiovascular health.
