国家健康访谈调查（NHIS）被用来确定睡眠不足的增加是否对黑人和白色美国人有不同的影响。我们检验了这样一个假设，即睡眠不足的患病率估计在黑人中一直较高，并且时间变化对这两个阶层的影响不同。NHIS是一项正在进行的非住院美国成年人（≥18岁）横断面研究，提供社会人口统计学、健康风险和医学因素。睡眠时间被编码为极短睡眠[VSS]（<5小时）、短睡眠[SS]（5-6小时）或长睡眠[LS]（>8小时），参考7-8小时睡眠者。使用SAS可调用的SUDAAN对NHIS的复杂抽样设计进行了调整。在白人中，VSS的患病率从1977年到2009年增加了53%（1.5%到2.3%），SS的患病率增加了32%（19.3%到25.4%）; LS的患病率下降了30%（11.2%到7.8%）。在黑人中，VSS患病率增加了21%（3.3%至4.0%），SS患病率增加了37%（24.6%至33.7%）; LS患病率下降了42%（16.1%至9.4%）。调整后的多项式回归分析显示，白人睡眠不足的几率为：VSS（OR = 1.40，95% CI = 1.13-1.74，p < 0.001）、SS（OR = 1.34，95% CI = 1.25-1.44，p < 0.001）和LS（OR = 0.94，95% CI = 0.85-1.05，NS）。对于黑人，估计是：VSS（OR = 0.83，95% CI = 0.60-1.40，NS）、SS（OR = 1.21，95% CI = 1.05-1.50，p < 0.001）和LS（OR = 0.84，95% CI = 0.64-1.08，NS）。多年来，黑人和白人在睡眠不足的患病率方面存在特征性差异。估计睡眠不足的时间变化似乎取决于个人的种族/民族。
The National Health Interview Survey (NHIS) was used to ascertain whether increases in inadequate sleep differentially affected black and white Americans. We tested the hypothesis that prevalence estimates of inadequate sleep were consistently greater among blacks, and that temporal changes have affected these two strata differentially. NHIS is an ongoing cross-sectional study of non-institutionalized US adults (≥18 years) providing socio-demographic, health risk, and medical factors. Sleep duration was coded as very short sleep [VSS] (<5 h), short sleep [SS] (5–6 h), or long sleep [LS] (>8 h), referenced to 7–8 h sleepers. Analyses adjusted for NHIS’ complex sampling design using SAS-callable SUDAAN. Among whites, the prevalence of VSS increased by 53 % (1.5 % to 2.3 %) from 1977 to 2009 and the prevalence of SS increased by 32 % (19.3 % to 25.4 %); prevalence of LS decreased by 30 % (11.2 % to 7.8 %). Among blacks, the prevalence of VSS increased by 21 % (3.3 % to 4.0 %) and the prevalence of SS increased by 37 % (24.6 % to 33.7 %); prevalence of LS decreased by 42 % (16.1 % to 9.4 %). Adjusted multinomial regression analysis showed that odds of reporting inadequate sleep for whites were: VSS (OR = 1.40, 95 % CI = 1.13-1.74, p < 0.001), SS (OR = 1.34, 95 % CI = 1.25-1.44, p < 0.001), and LS (OR = 0.94, 95 % CI = 0.85-1.05, NS). For blacks, estimates were: VSS (OR = 0.83, 95 % CI = 0.60-1.40, NS), SS (OR = 1.21, 95 % CI = 1.05-1.50, p < 0.001), and LS (OR = 0.84, 95 % CI = 0.64-1.08, NS). Blacks and whites are characteristically different regarding the prevalence of inadequate sleep over the years. Temporal changes in estimates of inadequate sleep seem dependent upon individuals’ race/ethnicity.
