Results suggest that discrimination experiences accelerate biological aging in older African American males and females, alike. This finding helps advance our understanding of how discrimination generates greater disease vulnerability and premature death in African Americans. (PsycINFO Database Record

Purpose: Racial discrimination has long-term consequences for cardiovascular health, potentially by dysregulating acute physiological responses. However, the role of psychological factors that may be protective or increase vulnerability for dysregulated responses, such as racial identity, remains unclear. This study examines the association between racial discrimination and acute parasympathetic responses, and the role of racial centrality, private regard, public regard in this association. Methods: Black young adults (N = 119, M age = 19.45) recruited from a predominantly White institution in the southeastern United States completed an online survey (in which racial discrimination, racial identity, and control variables were reported) and a laboratory visit, during which they were exposed to a vignette of racial discrimination while their parasympathetic activity (indexed by respiratory sinus arrhythmia) was recorded.

The association between racial discrimination (discrimination) and stress-related alterations in the neuroendocrine response-namely, cortisol secretion-is well documented in African Americans (AAs). Dysregulation in production of cortisol has been implicated as a contributor to racial health disparities. Guided by Clark et al. (Am Psychol 54(10):805-816, 1999. doi: 10.1037/0003-066X.54.10.805 ) biopsychosocial model of racism and health, the present study examined the psychological pathways that link discrimination to total cortisol concentrations in AA males and females. In a sample of 312 AA emerging adults (45.5% males; ages 21-23), symptoms of anxiety, but not depression, mediated the relation between discrimination and total concentrations of cortisol. In addition, the results did not reveal sex differences in the direct and indirect pathways. These findings advance our understanding of racial health disparities by suggesting that the psychological consequences of discrimination can uniquely promote physiologic dysregulation in AAs.

BackgroundA growing body of research suggests that racial discrimination may affect the health of Black men and Black women differently.AimsThis study examined Black patients with diabetes mellitus (DM) in order to test gender differences in (1) levels of perceived racial discrimination in health care and (2) how perceived discrimination relates to glycemic control.MethodsA total of 163 Black patients with type 2 DM (78 women and 85 men) provided data on demographics (age and gender), socioeconomic status, perceived racial discrimination in health care, self-rated health, and hemoglobin A1c (HbA1c). Data were analyzed using linear regression.ResultsBlack men reported more racial discrimination in health care than Black women. Although racial discrimination in health care was not significantly associated with HbA1c in the pooled sample (b = 0.20, 95% CI = −0.41 −0.80), gender-stratified analysis indicated an association between perceived discrimination and higher HbA1c levels for Black men (b = 0.86, 95% confidence intervals (CI) = 0.01–1.73) but not Black women (b = −0.31, 95% CI = −1.17 to −0.54).ConclusionPerceived racial discrimination in diabetes care may be more salient for glycemic control of Black men than Black women. Scholars and clinicians should take gender into account when considering the impacts of race-related discrimination experiences on health outcomes. Policies should reduce racial discrimination in the health care.
