种族歧视对心脏功能有负面影响，但很少有研究考察种族歧视经历对心脏的更远端影响。本研究在两天的时间里对42名非裔美国人(AA)女性样本(N=42)进行了基于实验室的组间和组内种族歧视对心率变异性(HRV)和心率(HR)的短暂和长期影响。在第一天，这些女性在实验室里接受了来自欧洲裔美国人(EA)或AA邦联成员的模拟种族歧视。在第二天，这些女性回到实验室进行额外的生理记录和汇报。被EA同盟者侮辱的女性在第一天表现出较低的HRV，在第二天表现出略低的HRV。这些女性在第二天的心率也略高。第二天的HRV和HR效应不是通过对应激源的持之以恒的差异来调节的。研究结果表明，种族歧视--尤其是群体间的种族歧视--可能会对腹主动脉硬化患者的心脏活动产生短暂和长期的影响。
Racial discrimination negatively impacts cardiac functioning, but few studies examine the more distal cardiac effects of racial discrimination experiences. The present study examined the momentary and prolonged impact of lab-based intergroup and intragroup racial discrimination on heart rate variability (HRV) and heart rate (HR) in a sample (N = 42) of African American (AA) women across two days. On day one, the women were exposed to simulated racial discrimination from either a European American (EA) or AA confederate in the lab. On day two, the women returned to the lab for additional physiological recording and debriefing. Women insulted by the EA confederate exhibited lower HRV on day one and marginally lower HRV on day two. These women also exhibited marginally higher HR on day two. The HRV and HR effects on day two were not mediated by differences in perseveration about the stressor. The findings indicate that racial discrimination – particularly intergroup racial discrimination – may have both momentary and prolonged effects on cardiac activity in AAs.
