Show allEFFECTS OF LOW NEIGHBOURHOOD SOCIOECONOMIC STATUS ON INFLAMMATION, OXIDATIVE STRESS, AND RISK OF MORTALITY IN PATIENTS WITH CORONARY ARTERY DISEASE
Abstract
Background: Socioeconomicstatus (SES) is an influential determinant of prognosis in coronary artery disease (CAD). Patient neighbourhood SES may contribute to CAD outcomes, beyond effects of personal SES.
Methods: Following 485 CAD patients for > 10 years, we examine the effect of neighbourhood income, education, and unemployment on survival, and investigate relationships between SES and markers of inflammation and oxidative stress.
Results: SES was associated significantly with risk of mortality, however this relationship was not observed for cardiovascular death. Each one quintile decrease in income, education, and employment was associated with a 32%, 40% and 45% greater risk of non-cardiovascular mortality, respectively. Inflammatory and oxidative stress markers correlate with income, but do not diminish associations between neighbourhood SES and mortality.
Conclusions: Significant disparities in non-cardiovascular mortality related to neighbourhood SES were observed in this study, which argues for greater attention to socioeconomic factors in chronic disease prevention and health care delivery.
