Abstract 15536: Impact of Social Determinants of Health on Atherosclerotic Cardiovascular Diseases Incidence

Abstract

INTRODUCTION: Individuals with an unfavorable socioeconomic status have a higher risk of developing chronic diseases such as atherosclerotic cardiovascular disease (ASCVD). However, the shared contribution of socioeconomic status, psychosocial factors and living environment on ASCVD risk remains unknown. We investigated the contribution of these social determinants of health on the incidence of ASCVD. METHODS: We developed a polysocial risk score (PsRS) using latent class analysis based on socioeconomic factors (household income, level/quality of education and employment status), psychosocial factors (living alone, social support, social activities, social isolation, emotional distress, and diagnosis of psychiatric disorders), and living environment (social deprivation score, crime rate, housing quality, housing stability, proximity to green/blue spaces and proximity to nature). The study sample included 319 842 participants of the UK Biobank, free of ASCVD recruited between 2006 and 2010. As of August 2021, 23 840 of them had incident ASCVD (fatal or nonfatal myocardial infarction, ischemic stroke, or cardiac revascularization procedures). Participants were divided into three groups based on latent class analysis adjusted for age. The impact of the PsRS on incident ASCVD was assessed using Cox proportional hazards for all participants, women and men adjusted for age, sex, and ethnicity. RESULTS: Compared to participants with a low PsRS, those with an intermediate score had a slightly higher risk of ASCVD (hazard ratio [HR]=1.05 [95% CI, 1.01-1.09], p=0.024) while those with a high PsRS had a higher risk of ASCVD (HR=1.46 [95% CI, 1.40-1.52], p<0.001). The effect of the PsRS on ASCVD incidence appeared to be more pronounced in women (HR=1,59 [95% CI, 1.48-1.71], p<0.001 and HR=1.39 [95% IC, 1.32-1.46], p<0.001, respectively, for women and men with a high PsRS compared to individuals with a low PsRS within the same sex). CONCLUSION: A PsRS based on the living environment as well as socioeconomic and psychosocial factors was associated with incident ASCVD in participants of the UK Biobank. Multifactor approaches targeting both social determinants of health and traditional risk factors could reduce the burden of ASCVD in the general population.
