这项准实验研究探讨了协会的感知种族主义和寻求社会支持血管反应性在一所大学的样本110名黑人妇女。通过自我报告评估了感知到的种族主义和寻求社会支持，并在标准化说话任务之前和期间测量了血管反应性。分层回归分析表明，感知种族主义与收缩压的变化呈正相关。这些分析还表明，寻求社会支持缓和感知种族主义和收缩压变化之间的关系。在控制了几个潜在的混杂因素后，这种相互作用仍然存在。后续的回归分析表明，种族主义与寻求社会支持的参与者之间的反应呈正相关。在寻求社会支持的参与者中，没有观察到明显的种族主义和收缩压变化之间的关系。种族歧视和寻求社会支持与舒张压的变化没有显着相关。这些研究结果强调了研究心理社会因素的重要性，这些因素可能会减轻种族主义和反应之间的假设关系。
This quasi-experimental study explored the association of perceived racism and seeking social support to vascular reactivity in a college sample of 110 Black women. Perceived racism and seeking social support were assessed via self-report, and vascular reactivity was measured before and during a standardized speaking task. Hierarchical regression analyses indicated that perceived racism was positively related to changes in systolic blood pressure. These analyses also indicated that seeking social support moderated the relationship between perceived racism and systolic blood pressure changes. This interaction effect persisted after controlling for several potential confounders. Follow-up regression analyses showed that perceived racism was positively associated with reactivity among participants who were low in seeking social support. A significant relationship was not observed between perceived racism and systolic blood pressure changes among participants who were high in seeking social support. Perceived racism and seeking social support were not significantly associated with changes in diastolic blood pressure. These findings highlight the importance of examining psychosocial factors that may mitigate the hypothesized relationship between perceived racism and reactivity.
