To examine racial differences in sleep duration and its relationship with diabetes.
We used data from a nationally representative sample of U.S. adults (n = 130,943) participating in the National Health Interview Survey from 2004 to 2011. Usual sleep duration was self-reported and categorized as <7 h (short), 7 h (optimal), and >7 h (long). Diabetes status was based on self-reported diagnosis from a health professional.
Participants' mean age was 50.6 years, 49% were men, and 13% were black. Compared with whites, blacks were more likely to report short sleep (37 vs. 28%) and less likely to get 7 h of sleep (24 vs. 33%). Diabetes (9,643 cases [9%] in whites and 3,612 cases [15%] in blacks) had a U-shaped distribution with sleep in whites (10, 7, and 9%, for short, optimal, and long sleep, respectively) and blacks (16, 13, and 15%). Suboptimal sleep duration was more strongly associated with diabetes in whites than in blacks among short (prevalence ratio 1.49 [95% CI 1.40-1.58] vs. 1.21 [1.09-1.34]) and long (1.32 [1.25-1.40] vs. 1.11 [1.00-1.23]) sleepers on the relative scale. Adjustment for socioeconomic status (SES) attenuated the short sleep-diabetes association in blacks (1.15 [1.02-1.29]), and the racial/ethnic difference in the short sleep-diabetes association became nonsignificant after SES adjustments.
Suboptimal sleep duration was positively associated with diabetes in blacks and whites, although diabetes prevalence was higher at any level of sleep in blacks. Socioeconomic factors appear to partly explain the association for short sleep in blacks as well as disparity between racial groups.
研究睡眠时间的种族差异及其与糖尿病的关系。
我们使用了来自2004年至2011年参与美国国家健康访谈调查的具有全国代表性的美国成年人样本（n = 130,943）的数据。通常的睡眠时间通过自我报告获得，并分为<7小时（短）、7小时（最佳）和>7小时（长）。糖尿病状态基于卫生专业人员的自我报告诊断。
参与者的平均年龄为50.6岁，49%为男性，13%为黑人。与白人相比，黑人更有可能报告睡眠时间短（37%对28%），而获得7小时睡眠的可能性较小（24%对33%）。糖尿病（白人中有9643例[9%]，黑人中有3612例[15%]）在白人（短、最佳和长睡眠者中分别为10%、7%和9%）和黑人（16%、13%和15%）中呈U形分布。在短睡眠者（患病率比值1.49[95%可信区间1.40 - 1.58]对1.
