生物学证据表明，民族-种族在早晚型上的差异是可能的，黑人可能比白人更有可能是早晨型。然而，人口水平的证据民族种族差异的早晚类型是有限的。在早期的一项研究中，我们报告说，在英国（UK）生物样本库队列（N = 439 933）中，与白人相比，黑人中的早晨型更为普遍。本研究旨在确定在考虑了更广泛的社会，环境和个人特征并采用模拟观察数据随机化的分析方法，倾向评分模型后，这些民族种族差异是否持续存在。使用了来自英国生物银行参与者的数据，这些参与者自我认定的种族/民族是黑人/英国黑人或白色;没有报告白天午睡、轮班工作或夜班工作;提供了完整的心理健康信息;使用倾向评分匹配确定（N = 2044）。每个样本在所有社会、环境和个人特征上都非常匹配，如所有变量的绝对标准化平均差异<0.09所示。采用多项logistic回归模型，将黑人（n = 1022）与白人（n = 1022）的匹配样本报告夜间短、充足和长睡眠以及早晨、中间和晚上类型的患病率进行比较。与白人相比，黑人早晨型的几率高出62%[比值比（OR）= 1.620，95%置信区间（CI）：1.336-1.964，p < .0001]，夜间短睡眠的几率高出3倍多（OR = 3.453，95% CI：2.846-4.190，p < .0001）。这些数据表明，与白人相比，黑人中早晨类型和夜间睡眠时间较短的患病率较高，这并不能完全由广泛的社会和环境因素解释。如果睡眠是健康的上游决定因素，这些数据表明，需要有针对性的民族和种族的公共卫生睡眠干预策略。
Biological evidence suggests that ethno-racial differences in morning–evening type are possible, whereby Blacks may be more likely to be morning type compared to Whites. However, population-level evidence of ethno-racial difference in morning–evening type is limited. In an earlier study, we reported that morning type was more prevalent in Blacks compared to Whites in the United Kingdom (UK) Biobank cohort (N = 439 933). This study aimed to determine if these ethno-racial differences persisted after accounting for an even broader range of social, environmental and individual characteristics and employing an analytic approach that simulates randomization in observational data, propensity score modeling. Data from UK Biobank participants whose self-identified race/ethnicity was Black/Black British or White; who did not report daytime napping, shift work or night shift work; who provided full mental health information; and who were identified using propensity score matching were used (N = 2044). Each sample was strongly matched across all social, environmental and individual characteristics as indicated by absolute standardized mean differences <0.09 for all variables. The prevalence of reporting nocturnal short, adequate and long sleep as well as morning, intermediate and evening type among Blacks (n = 1022) was compared with a matched sample of Whites (n = 1022) using multinomial logistic regression models. Blacks had a 62% greater odds of being morning type [odds ratio (OR) = 1.620, 95% confidence interval (CI): 1.336–1.964, p < .0001] and a more than threefold greater odds of reporting nocturnal short sleep (OR = 3.453, 95% CI: 2.846–4.190, p < .0001) than Whites. These data indicate that the greater prevalence of morning type and short nocturnal sleep in Blacks compared to Whites is not fully explained by a wide range of social and environmental factors. If sleep is an upstream determinant of health, these data suggest that ethno-racially targeted public health sleep intervention strategies are needed.
