Chronic stress exposure may contribute to dysregulation of cardiovascular functions and increase CVD risk among African Americans. This study investigated the direct and interactive effects of chronic stress exposure and coping styles on cardiovascular reactivity to acute stress. A sample of African American emerging adults (n = 277) completed a battery of self-report assessments and underwent the Trier Social Stress Test (TSST) across two time points. Prior chronic stress exposure was negatively associated with heart rate (HR) reactivity among females at 1-month follow-up. Task-oriented coping was positively associated with HR reactivity, while avoidance-oriented coping showed a negative association. Higher use of emotion-oriented coping moderated the relationship between chronic stress exposure and HR reactivity, resulting in more robust reactivity. Among females, but not males, lower use of avoidance-oriented coping moderated the relationship between prior chronic stress exposure and HR reactivity, also resulting in more robust reactivity. Prior chronic stress exposure and the use of maladaptive coping strategies may confer negative impacts on cardiovascular reactivity, particularly among African American females. Using adaptive coping styles may mitigate these effects and improve cardiovascular reactivity. These findings provide preliminary support for psychosocial determinants of health within a controlled laboratory experiment and highlight important gender differences to consider in prevention efforts for African American cardiovascular health disparities.
