Abstract
Objective: Social determinants may negatively affect health via Hypothalamic-Pituitary-Adrenal (HPA) axis dysfunction. The potential contribution of social determinants and related factors to HPA-axis functioning is important to study among African American adults, who are more likely to experience societal inequities and health disparities relative to other racial/ethnic groups. This study examined the relationship between depressive symptoms and perceived social control on HPA-axis functioning among African American adults. Method: Participants (N = 107; Mage = 50, 79% female) were administered measures including the Center for Epidemiologic Studies-Depression and Informal (neighborhood) Social Control. Study procedures included the provision of 6 saliva samples for cortisol analysis (at wakeup, 30-and 90-min post-wakeup, 2:00 PM, 5:00 PM, and prebedtime). The relationship between depression and social control on the functioning of the HPA-axis were simultaneously examined within a 2-level hierarchical linear model. Results: Variability in the Cortisol Awakening Response (CAR) was accounted for by depressive symptomatology (p = .023) and perceived social control (p = .016), whereby greater depression was associated with a blunted CAR (less awakening cortisol production) and greater perceptions of neighborhood social control with a higher CAR. Conclusions: Elevated depressive symptoms and low perceptions of neighborhood social control may serve as mechanisms that help to explain within-group variability in the functioning of stress physiology among African American adults. Findings enhance understanding of how social determinants may affect African Americans' health.
