摘要

<strong>Background:</strong> African Americans (AA) are disproportionally affected by cardiovascular disease as compared to other racial-ethnic groups. Exposure to adverse socioeconomic conditions may partially explain disparities in risk factors and prevalence and cardiovascular diseases for AA. We aim to study the impact of poverty status on metabolic syndrome (MetS) and its components among African Americans. <strong>Methods:</strong> We used data from the National Health and Nutritional Examination Survey (NHANES) cycles 2001-2006. We defined MetS using the Joint Scientific Definition as the presence of any 3/5 components: elevated blood pressure (BP), elevated triglycerides (TGL), lower high-density lipoprotein cholesterol (LDL), elevated fasting plasma glucose (FPG), and elevated waist circumference (WC). Poverty to income ratio (PIR) was categorized as below poverty (<1), above poverty (1 - 3) and high income (>3) groups. We used multivariable survey-weighted logistic regression models to study the impact of poverty status of prevalence of MetS and its components among AA men and women. <strong>Results:</strong> Overall, the average aggregate prevalence of MetS among AA sample was 22% in our study with prevalence being 25% for women and 18% among men (p < 0.001). In regression models, among women, living below poverty (PIR < 1) was associated with a higher prevalence/odds of having metabolic syndrome compared to those living in the high-income group (PIR > 3) (OR = 1.57, 95%CI = 1.00 - 2.46, p = 0.05) with no association observed among men (OR (PIR < 1 vs PIR >= 1) = 0.70, 95%CI = 0.43 - 1.19, p = 0.13). Further, similar associations were observed for individual components among women including: elevated waist circumference (OR = 2.04, 95%CI = 1.37, 3.01, p < 0.001), elevated triglycerides (OR = 1.85, 95%CI = 1.02 - 3.36, p = 0.04), reduced HDL (OR = 2.04, 95%CI = 1.15, 3.60, p = 0.02) and elevated blood pressure (OR = 2.16, 95%CI = 1.34 - 3.49, p = 0.002) as compared to women in high income group (PIR > 3
