Health disparities among African Americans have been reported for decades. This is especially true for cardiovascular disease (CVD) even when compared with other minority groups in America. Such disparities have been tied to perceived discrimination. A previous study found that perceived racism accounted for a substantial percentage of the variance in resting heart rate variability (HRV), an independent biomarker of cardiac health. The present study attempts to replicate such findings. This study includes 57 healthy African American individuals who met inclusion criteria. Participants were given the Perceived Ethnic Discrimination Questionnaire–Community Version (PEDQ-CV) and the Perceived Racism Scale (PRS) and had their resting HRV and blood pressure measured. After accounting for breathing rate and age, the lifetime score on the PRS uniquely accounted for up to 45% of the variability of HRV metrics. The PEDQ-CV was not found to be a statistically significant predictor of HRV. Within this sample, blood pressure was not significantly predicted by either scale. The findings suggest that lifetime perceived racism may directly affect HRV indices, which may indicate an increased risk for CVD. Further research should continue to investigate this association and potential avenues for related intervention. [ABSTRACT FROM AUTHOR] |
