This study examined the relationship of cardiovascular reactivity to both interpersonal mistreatment and discrimination in a community-based sample of African American and European American women (N=363) in midlife. Subtle mistreatment related positively to diastolic blood pressure (DBP) reactivity for African American participants but not their European American counterparts. Moreover, among the African American participants, those who attributed mistreatment to racial discrimination exhibited greater average DBP reactivity. In particular, these women demonstrated greater DBP reactivity to the speech task, which bore similarities to an encounter with racial prejudice but not to a nonsocial mirror tracing task. These findings are consistent with the hypothesis that racial discrimination is a chronic stressor that can negatively impact the cardiovascular health of African Americans through pathogenic processes associated with physiologic reactivity.
本研究在一个以社区为基础的中年非裔美国女性和欧裔美国女性样本（N = 363）中，考察了心血管反应性与人际虐待和歧视之间的关系。对于非裔美国参与者而言，微妙的虐待与舒张压（DBP）反应性呈正相关，但欧裔美国参与者并非如此。此外，在非裔美国参与者中，那些将虐待归因于种族歧视的人表现出更高的平均DBP反应性。特别是，这些女性在言语任务中表现出更大的DBP反应性，该任务类似于遭遇种族偏见，但与非社会性的镜像追踪任务不同。这些发现与以下假设一致：种族歧视是一种慢性应激源，可通过与生理反应相关的致病过程对非裔美国人的心血管健康产生负面影响。
