Expectations of Racism and Carotid Intima-Media Thickness in African American Women.

Abstract

Several researchers have argued that racism-related stressors play an important role in adverse cardiovascular outcomes among African American women. However, studies have primarily focused on experiences of racism; thus, the role of expectations of racism is insufficiently understood. The current proof-of-concept study was designed to examine associations among expectations of racism, self-reported experiences of racism, and carotid intima-media thickness (IMT), a marker of cardiovascular risk, in African American women. Participants were 52 healthy African American women, aged 30 to 50 years (M (SD) = 40.8 (4.3)). Expectations of racism were assessed with a modified version of the Race-Based Rejection Sensitivity Questionnaire, experiences of racism were assessed with the Schedule of Racist Events, and carotid IMT was measured using B-mode ultrasound. In linear regression analyses adjusted for age, expectations of racism were associated with higher levels of carotid IMT (b = .04, SE = .014, p = .013), after adjusting for experiences of racism. Findings remained significant after additional adjustments for cardiovascular risk factors (b = .03, SE = .014, p = .032). Associations were not confounded by additional stressors, hostility, or negative affect (depressive symptoms). Independent of actual reports of racism, "expectations" of racism may be associated with increased cardiovascular risk in African American women. In addition, although experiences of discrimination were associated with depressive symptoms, expectations of racism were not, suggesting that other negative emotions likely play a role. Future studies are needed to replicate these results in larger samples and to explore the psychological and physiological pathways through which expectations of racism might affect cardiovascular disease risk across a range of populations.
