PURPOSE
To examine the associations of the frequency and type of everyday discrimination with diurnal cortisol and whether those associations depend upon adolescents' ethnicity and gender.
METHODS
Adolescents (N=292, Mage=16. 39years, SD=0.74; 58% female) reported the frequency of perceived everyday discrimination and whether they attributed that discrimination to race, gender, age, or height and weight. Five saliva samples were collected per day across 3days and assayed for cortisol.
RESULTS
Higher frequency of everyday discrimination was associated with greater total daily cortisol output (area under the curve; AUC), lower wake and bedtime levels of cortisol, and less of a decline in cortisol across the day. These associations generally did not depend upon ethnicity or gender and attributions for the discrimination were not as consequential as the actual frequency of any type of unfair treatment.
CONCLUSION
Everyday discrimination, regardless of its type, may contribute to heightened HPA activity among adolescents of different ethnic backgrounds and genders.
目的
探讨日常歧视的频率和类型与昼夜皮质醇之间的关联，以及这些关联是否取决于青少年的种族和性别。
方法
青少年（N = 292，平均年龄Mage = 16.39岁，标准差SD = 0.74；58%为女性）报告了他们感知到的日常歧视的频率，以及他们是否将这种歧视归因于种族、性别、年龄或身高体重。在3天内每天收集5份唾液样本，并检测皮质醇水平。
结果
日常歧视频率较高与每日皮质醇总输出量（曲线下面积；AUC）增加、醒来和就寝时的皮质醇水平较低以及全天皮质醇下降较少有关。这些关联通常不取决于种族或性别，歧视的归因不如任何类型的不公平待遇的实际频率重要。
结论
无论日常歧视的类型如何，都可能导致不同种族背景和性别的青少年的下丘脑-垂体-肾上腺（HPA）活动增强。
