关于种族歧视和高血压风险的实证研究结果并不一致。一些研究发现，自我报告的歧视经历与心血管健康结果之间没有关联，而另一些研究则发现了适度或曲线关系。目前的横断面研究探讨了种族歧视和高血压之间的关联是否受到非裔美国中年男性内隐种族偏见的影响。这项研究调查了91名年龄在30-50岁之间的非洲裔美国男性的数据。主要变量是自我报告的种族歧视的经验，和无意识的种族偏见，衡量的黑-白内隐联想测试。指定改良泊松回归模型检查高血压，定义为平均静息收缩压≥ 140 mm Hg或舒张压≥ 90 mm Hg;或自我报告的心血管药物使用史，医生诊断为高血压。没有发现歧视或内隐种族偏见的主效应，但两个变量的交互作用与高血压显著相关（χ2 = 4.89，1df，p < 0.05）。在具有内隐反黑人偏见的参与者中，更频繁的歧视报告与高血压的概率较高相关，而在具有内隐亲黑人偏见的参与者中，它与风险较低相关。经历种族歧视和持有反黑人偏见的组合可能对非裔美国中年男性的高血压产生特别有害的后果，而持有隐性的亲黑人偏见可能会缓冲种族歧视的影响。努力解决内在的种族偏见和种族歧视可能会降低这一人群的心血管风险。
Empirical findings on racial discrimination and hypertension risk have been inconsistent. Some studies have found no association between self-reported experiences of discrimination and cardiovascular health outcomes while others have found moderated or curvilinear relationships. The current cross-sectional study examined whether the association between racial discrimination and hypertension is moderated by implicit racial bias among African American midlife men. This study examined data on 91 African American men between 30-50 years of age. Primary variables were self-reported experiences of racial discrimination; and unconscious racial bias as measured by the Black-White Implicit Association Test. Modified Poisson regression models were specified examining hypertension, defined as mean resting systolic ≥ 140 mm Hg or diastolic ≥ 90 mm Hg; or self-reported history of cardiovascular medication use with a physician diagnosis of hypertension. No main effects for discrimination or implicit racial bias were found, but the interaction of the two variables was significantly related to hypertension (χ2 = 4.89, 1 df, p < 0.05). Among participants with an implicit anti-Black bias, more frequent reports of discrimination were associated with a higher probability of hypertension, while among those with an implicit pro-Black bias, it was associated with lower risk. The combination of experiencing racial discrimination and holding an anti-Black bias may have particularly detrimental consequences for hypertension among African American midlife men, while holding an implicit pro-Black bias may buffer the effects of racial discrimination. Efforts to address both internalized racial bias and racial discrimination may lower cardiovascular risk in this population.
