Short and long sleep duration are associated with poor health outcomes and are most prevalent among racial/ethnic minorities. Few studies have investigated the intersection of other sociodemographic characteristics with race/ethnicity on sleep duration prevalence.
Longitudinal retrospective analysis of continental U.S. cohort, the REasons for Geographic And Racial Differences in Stroke (REGARDS) PARTICIPANTS: Black (n = 7,547) and white (n = 12,341) adults, 56% women, ≥45 years MEASUREMENTS: At baseline (2003-07), participants reported age, sex, race, education, income, marital status, U.S. region, and employment status. The weighted average of reported sleep duration on weekdays and weekends, assessed at follow-up (2008-10), was categorized as <6, 6.0-6.99, 7.0-7.99 [reference], 8.0-8.99, and ≥9 h. Multinomial logistic regression models examined the independent and multivariable associations of sociodemographic factors with sleep duration. Interactions terms between race with education, income, region, and sex were examined.
Average sleep duration was 7.0 h (SD=1.3). Prevalence of short (<6 h) and long (≥9 h) sleep duration was 11.4% (n = 2,260) and 7.0% (n = 1,395), respectively. In the multivariable model, interactions terms raceincome, racesex, and race*region were significant (P < .05). Relative to white adults, black adults, were most likely to have short sleep duration. The magnitude of that likelihood increased across greater levels of household income, but with greatest odds among black adults living outside of the Southeast and Appalachian United States, particularly for men (≥$75k; black men OR = 5.47, 95%CI: 3.94,7.54; black women OR = 4.28, 95%CI: 3.08, 5.96).
Race in the context of socioeconomic, sex, and regional factors should be examined as key modifiers of sleep duration.
短睡眠和长睡眠时长与健康状况不佳有关，在少数族裔中最为常见。很少有研究调查其他社会人口特征与种族/民族对睡眠时长流行率的交叉影响。
美国大陆纵向回顾性分析，REasons for Geographic And Racial Differences in Stroke（REGARDS）参与者：黑种人（n=7547）和白种人（n=12341）成年人，女性占 56%，年龄≥45 岁。
在基线（2003-07 年）时，参与者报告了年龄、性别、种族、教育程度、收入、婚姻状况、美国地区和就业状况。在随访（2008-10 年）时报告的工作日和周末的平均睡眠时长加权平均值分为<6、6.0-6.99、7.0-7.99[参考值]、8.0-8.99 和≥9h。多变量逻辑回归模型检查了社会人口因素与睡眠时长的独立和多变量关联。还检查了种族与教育、收入、地区和性别之间的交互项。
平均睡眠时长为 7.0 小时（SD=1.3）。短睡眠（<6 小时）和长睡眠（≥9 小时）的患病率分别为 11.4%（n=2260）和 7.0%（n=1395）。在多变量模型中，种族收入、种族性别和种族*地区的交互项具有统计学意义（P<0.05）。与白种成年人相比，黑种成年人更有可能出现短睡眠。随着家庭收入水平的提高，这种可能性的幅度增加，但在美国东南部和阿巴拉契亚地区以外生活的黑种成年人中，这种可能性最大，尤其是男性（≥$75k；黑种男性 OR=5.47，95%CI：3.94，7.54；黑种女性 OR=4.28，95%CI：3.08，5.96）。
在社会经济、性别和区域因素的背景下，种族应作为睡眠时长的关键调节因素进行检查。
