Discrimination Is Associated with Elevated Cardiovascular Disease Risk among African Immigrants in the African Immigrant Health Study

Abstract

Background: African Americans and other persons of African descent in the United States are disproportionately affected by cardiovascular diseases (CVD). Discrimi­nation is associated with higher CVD risk among US adults; however, this relationship is unknown among African immigrants.Objective: To examine the associations among discrimination, resilience, and CVD risk in African immigrants.Methods: The African Immigrant Health Study was a cross-sectional study of African immigrants in Baltimore-Washington, DC, with recruitment and data collection taking place between June 2017 and April 2019. The main outcome was elevated CVD risk, the presence of ≥3 CVD risk factors includ­ing hypertension, diabetes, high choles­terol, overweight/obesity, tobacco use, and poor diet. The secondary outcomes were these six individual CVD risk factors. The exposure was discrimination measured with the Everyday Discrimination Scale; summed scores ≥2 on each item indicated frequent experiences of discrimination. Resilience was assessed with the 10-item Connor- Davidson resilience scale. Logistic regression was used to examine the odds of elevated CVD risk, adjusting for relevant covariates.Results: We included 342 participants; 61% were females. The mean (±SD) age was 47(±11) years, 61% had at least a bachelor’s degree, 18% had an income <$40,000, and 49% had lived in the US ≥15 years. Persons with frequent experi­ences of discrimination were 1.82 times (95%CI: 1.04–3.21) more likely to have elevated CVD risk than those with fewer experiences. Resilience did not moderate the relationship between CVD risk and discrimination.Conclusion: African immigrants with frequent experiences of discrimination were more likely to have elevated CVD risk. Tar­geted and culturally appropriate interven­tions are needed to reduce the high burden of CVD risk in this population. Health care providers should be aware of discrimina­tion as a meaningful social determinant of CVD risk. At the societal level, policies and laws are needed to reduce the occurrence of discrimination among African immi­grants and racial/ethnic minorities.
