INTRODUCTION The new American Heart Association Life's Essential 8 construct of ideal cardiovascular health now includes sleep duration. Little is known, however, about sleep duration in individuals with prior stroke. Our objective was to compare sleep duration among individuals with and without prior stroke. METHODS Using the National Health and Nutrition Examination Surveys (NHANES) database (2005-2018), individuals 18 years or older were identified (n = 37,987 without self-reported stroke; n = 1,572 with self-reported stroke). Prevalence of normal sleep duration (7-8 or 6-8 hours/night because of multiple definitions in the literature) was compared between persons with and without self-reported history of stroke using the Rao-Scott χ2 test. Multinomial logistic regression analysis was used to evaluate the relationship between prior stroke and abnormal sleep before and after adjusting for demographic and clinical variables. RESULTS Compared with individuals without stroke, those with prior stroke were more likely to report >8 hours/night (unadjusted odds ratio (OR) 2.03, 95% confidence interval (CI) 1.64-2.51), <7 hours/night (1.29, 1.08-1.53), and <6 hours/night (1.87, 1.53-2.29). After adjustment, these associations were attenuated (adjusted OR 1.54, 95% CI 1.22-1.94 and 1.15, 0.96-1.38 and 1.50, 1.21-1.85). DISCUSSION US stroke survivors are more likely to have abnormal sleep duration than those without prior stroke. Limitations of this study include the cross-sectional and self-reported nature of the data.

美国睡眠时间异常与中风之间的关联。


简介 新的美国心脏协会 Life's Essential 8 理想心血管健康构建现在包括睡眠时间。然而，人们对于中风患者的睡眠持续时间知之甚少。我们的目标是比较有和没有中风史的个体的睡眠持续时间。方法 使用国家健康和营养检查调查 (NHANES) 数据库（2005-2018 年），确定了 18 岁或以上的个体（n = 37,987 名没有自我报告中风的人；n = 1,572 人有自我报告中风的人）。使用 Rao-Scott χ2 检验比较有和没有自我报告中风病史的人之间正常睡眠时间（7-8 或 6-8 小时/晚，因为文献中有多种定义）的患病率。使用多项逻辑回归分析来评估人口统计和临床变量调整前后既往卒中与睡眠异常之间的关系。结果 与没有中风的个体相比，既往中风的患者更有可能报告 >8 小时/夜（未调整优势比 (OR) 2.03，95% 置信区间 (CI) 1.64-2.51）、<7 小时/夜（1.29， 1.08-1.53​​) 和 <6 小时/夜 (1.87、1.53-2.29)。调整后，这些关联性减弱（调整后 OR 1.54，95% CI 1.22-1.94 和 1.15、0.96-1.38 和 1.50、1.21-1.85）。讨论 与没有中风史的人相比，美国中风幸存者更有可能出现睡眠时间异常的情况。这项研究的局限性包括数据的横截面和自我报告性质。
