Discrimination is a form of chronic stress and hair cortisol concentration is an emerging biomarker of chronic stress. In a sample of 83 first-year college students (age , , 69% female, 84% United States-born, 24% Asian, 21% Latinx, and 55% White), the current study investigates associations between hair cortisol concentration with discrimination stress assessed across two timeframes: past year and past two weeks. Significant associations were observed for past year discrimination and hair cortisol concentration levels, but not for discrimination over the past two weeks. The current study contributes to a growing body of evidence linking discrimination stress exposure to neuroendocrine functioning.
歧视是一种慢性应激形式，而头发皮质醇浓度是一种新兴的慢性应激生物标志物。在83名大学一年级学生（年龄[具体年龄范围未给出]，平均年龄[具体平均年龄未给出]，69%为女性，84%在美国出生，24%为亚洲人，21%为拉丁裔，55%为白人）的样本中，本研究调查了在两个时间框架内评估的头发皮质醇浓度与歧视应激之间的关联：过去一年和过去两周。观察到过去一年的歧视与头发皮质醇浓度水平之间存在显著关联，但过去两周的歧视则不然。本研究为越来越多的将歧视应激暴露与神经内分泌功能联系起来的证据做出了贡献。
