Heart rate variability as a physiological moderator of the relationship between race-related stress and psychological distress in African Americans.
This study examined the moderator effects of heart rate variability, a physiological marker of stress vulnerability, on the relationship between race-related stress and psychological distress in African Americans (N = 215). Participants were administered the Index of Race-Related Stress-Brief and the Brief Symptom Inventory-18. Resting heart rate was recorded using the Polar 810s heart rate monitor. Findings indicated that heart rate variability moderated the relationship between institutional race-related stress and psychological distress for men, but not women. These findings suggest that higher levels of resting heart rate variability may buffer African Americans from the deleterious effects of race-related stress.
