Abstract 17598: Low Socioeconomic Status Leads to Higher Cardiovascular Mortality in the United States

Abstract

Introduction: Lower socioeconomic status can lead to chronic disease. However, there is a dearth of information as to how it pertains to organ-specific mortality. Hypothesis: In this study, we determined if there was a connection longitudinally between poverty-income-ratio (PIR) and cardiovascular mortality Methods: We conducted a study which assessed for all adult (≥ 20 years) individuals from the 1999-2010 National Health and Nutrition Examination Survey, which is a population-based survey conducted with cardiovascular mortality data obtained through December 2019. All individuals from this were living in the United States. Socioeconomic status was determined using total family income divided by the poverty threshold (≤1 versus >1). Comparisons were analyzed using Complex Samples Cox regression to determine the relationship of poverty-income-ratio and cardiovascular mortality. Results: Data was available for 13,680 adults in the United States population. Mean time period of males (8.3 years (CI 8.0-8.5) who experienced death was higher than the mean time period among females 8.8 years (CI 8.6-9.0). The overall age-adjusted, sex-adjusted hazard ratio for high PIR to low PIR is 1.73 (1.39-2.16, p < 0.01). The adjusted HR remained strong at 1.98 (CI 1.18-3.33, p < 0.01) among adults after the results were controlled for medical (obesity, depression) and demographic (gender, age, and ethnicity) risk factors. Conclusions: There is a significant relationship between low socioeconomic status and cardiovascular mortality among all adults. Consequently, individuals with cardiovascular disease need to be better screened for social determinants of health.
