种族主义与美国本土人口的身体健康之间的联系尚未得到研究，尽管他们患压力相关疾病的风险很高，而且有歧视他们的历史。我们研究了146名成年夏威夷原住民的感受种族主义与皮质醇水平和血压这两项生理应激指标之间的相关性。使用10个项目的简化版压迫问卷对被归因于种族主义和感觉到种族主义进行评估。收集和分析了身高、体重、血压和唾液皮质醇样本(AM和PM)，以及夏威夷血统、BMI、年龄、性别、婚姻状况、教育水平、一般心理压力和种族认同等信息。结果表明，在调整了社会人口、生物和心理社会混杂因素后，报告更多归因于种族主义的夏威夷原住民的平均皮质醇水平显著低于报告更少归因于种族主义的人(P<；.05)。报告更多种族主义的夏威夷原住民比报告更少的夏威夷原住民的收缩压显著更高，但在调整前述混杂因素后，这种关联并不显著。种族主义似乎是一种慢性应激源，可能通过皮质醇失调的机制，影响夏威夷原住民的身体健康和与压力相关的疾病的风险，从而“深入”夏威夷原住民。
The association between racism and the physical health of native U.S. populations has yet to be examined despite their high risk for stress-related disorders and a history of discrimination toward them. We examined the correlation between perceived racism and the two physiological stress indices of cortisol level and blood pressure in 146 adult Native Hawaiians. Attributed and felt racism were assessed with a 10-item shortened version of the Oppression Questionnaire. Height, weight, blood pressure, and salivary cortisol samples (AM and PM) were collected and analyzed along with information on Hawaiian ancestry, BMI, age, sex, marital status, education level, general psychological stress, and ethnic identity. The results indicated that Native Hawaiians reporting more attributed racism had significantly (P < .05) lower average cortisol levels than those reporting less attributed racism, after adjusting for socio-demographic, biological, and psychosocial confounders. Native Hawaiians reporting more felt racism had a significantly higher systolic blood pressure than those reporting less, but this association was not significant after adjusting for the aforementioned confounders. Racism appears to be a chronic stressor that can "get under the skin" of Native Hawaiians by affecting their physical health and risk for stress-related diseases, possibly, through mechanisms of cortisol dysregulation.
