Job discrimination, a social stressor, may lead to sleep health disparities among workers; yet, limited research has examined this relationship and specific sources of job discrimination. We used a US sample of working women (n = 26,085), participants in the Sister Study (2008-2016), to examine the associations of perceived job discrimination due to sex, race, age, health conditions, and/or sexual orientation with sleep health. Cross-sectionally, linear or logistic regression models revealed that each source of job discrimination was independently associated with different sleep problems after controlling for other sources of job discrimination. Longitudinally, among participants without short sleep (<7 hours/night) at time 1 (2012-2014), age-specific job discrimination was associated with 21% increased odds of new-onset short sleep (odds ratio = 1.21, 95% confidence interval: 1.03, 1.43) at time 2 (2014-2016). Among those without insomnia symptoms at time 1, race-specific job discrimination was associated with 37% increased odds of new-onset insomnia symptoms (odds ratio = 1.37, 95% confidence interval: 1.07, 1.75) at time 2. Sex- and health-specific job discrimination also predicted new-onset sleepiness. There were dose-response relationships such that a greater number of sources of job discrimination (≥3) was associated with greater odds of prevalent and incident sleep problems. Perceived job discrimination may contribute to working women's poor sleep health over time, raising concerns about sleep health disparities emanating from the workplace.
工作歧视是一种社会压力源，可能导致劳动者的睡眠健康状况存在差异；然而，目前的研究很少探讨这种关系以及工作歧视的具体来源。我们使用了一项来自美国的职业女性样本（n=26085），这些女性是姐妹研究（2008-2016）的参与者，以研究因性别、种族、年龄、健康状况和/或性取向而导致的工作歧视与睡眠健康之间的关系。在横断面研究中，线性或逻辑回归模型显示，在控制了其他来源的工作歧视后，每种工作歧视来源都与不同的睡眠问题独立相关。在纵向研究中，对于在第 1 时间点（2012-2014 年）没有短睡眠（<7 小时/夜）的参与者，特定年龄的工作歧视与新发生的短睡眠的几率增加 21%相关（比值比=1.21，95%置信区间：1.03，1.43），第 2 时间点（2014-2016 年）。在第 1 时间点没有失眠症状的参与者中，特定种族的工作歧视与新发生的失眠症状的几率增加 37%相关（比值比=1.37，95%置信区间：1.07，1.75）。性别和健康特定的工作歧视也预测了新发生的嗜睡。存在剂量-反应关系，即更多的工作歧视来源（≥3）与更高的常见和新发睡眠问题的几率相关。感知到的工作歧视可能会导致职业女性的睡眠健康状况随着时间的推移而恶化，这引发了对源于工作场所的睡眠健康差异的担忧。
