Black women experience disproportional rates of cardiovascular disease (CVD) warranting further exploration of CVD risk factors. Growing evidence suggests acute stress reactivity studies may elucidate the mechanisms driving psychosocial correlates of CVD risks. Race-related stress has been identified as a CVD risk factor among Black women though recent evidence suggests emotions may facilitate these risks. Black women may be vulnerable to shame related to frequent racist experiences. Yet, no study to date has examined racism, shame, and stress reactivity in this population. The current study utilized mixed linear models to test for time and group effects of racism and shame on stress reactivity (e.g., cortisol and C-reactive protein [CRP]) among 34 Black women who completed the Trier Social Stress Test. Tests for two-way interactions (i.e., shame by racism) were also performed. Significant time and group effects were observed for shame and racism on stress reactivity. Black women who experienced greater lifetime racism, stress appraised, but lower racism during the past year, exhibited greater CRP responses. Black women who experienced high levels of shame and racism during the past year and their lifetime demonstrated greater cortisol reactivity. These results prompt further research on racism and shame as CVD risk factors among Black women.
黑人女性患心血管疾病(CVD)的比例不成比例,这需要进一步探讨 CVD 的风险因素。越来越多的证据表明,急性应激反应研究可以阐明导致与 CVD 风险相关的心理社会因素的机制。种族相关压力已被确定为黑人女性的 CVD 风险因素,但最近的证据表明,情绪可能会增加这些风险。黑人女性可能容易因经常遭受种族主义而感到羞耻。然而,迄今为止,尚无研究在该人群中检查种族主义、羞耻和应激反应性。本研究使用混合线性模型,在 34 名完成特里尔社会应激测试的黑人女性中,检验了种族主义和羞耻感对应激反应(如皮质醇和 C 反应蛋白 [CRP])的时间和组效应。还进行了双向相互作用(即羞耻感与种族主义)的检验。在应激反应方面,观察到羞耻感和种族主义的时间和组效应显著。在过去的一年中经历了更多的终生种族主义、压力评估但种族主义较低的黑人女性,其 CRP 反应更高。在过去一年及其一生中经历了高种族主义和羞耻感的黑人女性,其皮质醇反应更高。这些结果促使我们进一步研究种族主义和羞耻感作为黑人女性 CVD 的风险因素。
