This study examined the effects of race-related stressors and hostility on cardiovascular reactivity in 31 African American and 31 Caucasian men. Participants viewed 3 film excerpts that depicted neutral, anger-provoking (but race-neutral), and racist situations. Participants exhibited significantly greater diastolic blood pressure reactivity to anger-provoking and racist stimuli compared with neutral stimuli. In addition, high hostility was associated with higher recovery systolic and diastolic blood pressure levels after exposure to the films. Although the results failed to confirm previous reports of greater reactivity to racism in African Americans, the findings suggest that diastolic blood pressure levels may remain elevated after exposure to racist stimuli. These results indicate that even indirect exposure to interpersonal conflict elicits significant reactivity, which can persist after exposure to the stressor, especially among high-hostile men.
本研究调查了31名非裔美国男性和31名白人男性中与种族相关的压力源和敌意对心血管反应性的影响。参与者观看了三段电影片段，分别描绘了中性、激怒性（但与种族无关）和种族主义情境。与中性刺激相比，参与者对激怒性和种族主义刺激表现出显著更高的舒张压反应性。此外，高敌意与观看电影后更高的收缩压和舒张压恢复水平相关。尽管结果未能证实先前关于非裔美国人对种族主义反应更强的报道，但研究结果表明，接触种族主义刺激后舒张压水平可能会持续升高。这些结果表明，即使是间接接触人际冲突也会引发显著的反应性，这种反应性在接触压力源后可能会持续存在，尤其是在高敌意男性中。
