To examine the protective effects of racial identity and Africentric worldview on the association between racial discrimination and blood pressure (BP).
Two hundred ten African American young adults completed questionnaires assessing demographic characteristics, prior racial discrimination experiences, racial identity, and Africentric worldview. Resting BP was assessed before and after completion of the study measures.
Racial discrimination was unrelated to BP in the overall sample (systolic BP, p = .444; diastolic BP [DBP], p = .915; mean arterial pressure, p = .774). However, racial identity and Africentric worldview moderated the association between racial discrimination and BP. Racial discrimination was negatively related to DBP for participants who felt that others viewed African Americans less favorably and who endorsed the uniqueness of the African American experience (B = -2.59, standard error [SE] = 1.29, p = .046). These individuals also had the lowest DBP at high levels of racial discrimination. Racial discrimination was positively associated with DBP for individuals with low levels of Africentric orientation (B = 1.43, SE = 0.72, p = .048) but was unrelated to DBP at moderate (B = 0.24, SE = 0.65, p = .718) and high (B = -0.96, SE = 1.01, p = .341) levels of Africentric worldview.
Racial and cultural personal characteristics such as racial identity and Africentric orientation may serve an important protective function for BP in African American young adults.
探讨种族认同和非裔中心世界观对种族歧视与血压（BP）之间关联的保护作用。
210 名非裔美国年轻成年人完成了调查问卷，内容包括人口统计学特征、先前的种族歧视经历、种族认同和非裔中心世界观。在完成研究措施前后测量静息血压。
在整个样本中，种族歧视与 BP 无关（收缩压，p =.444；舒张压[DBP]，p =.915；平均动脉压，p =.774）。然而，种族认同和非裔中心世界观调节了种族歧视与 BP 之间的关系。对于那些认为他人对非裔美国人评价较低且认同非裔美国人经历独特性的参与者，种族歧视与 DBP 呈负相关（B = -2.59，标准误差[SE] = 1.29，p =.046）。这些人在种族歧视程度较高时 DBP 最低。对于非裔中心取向水平较低的个体，种族歧视与 DBP 呈正相关（B = 1.43，SE = 0.72，p =.048），但在中等（B = 0.24，SE = 0.65，p =.718）和高水平（B = -0.96，SE = 1.01，p =.341）非裔中心世界观时与 DBP 无关。
种族和文化个体特征，如种族认同和非裔中心取向，可能对非裔美国年轻成年人的 BP 起到重要的保护作用。
