Assess the relationship of self-reported sleep quality and possible sleep disorders with disability in a racially diverse sample of community-dwelling older adults.
Participants included 943 non-demented older African Americans (n=452) and Whites (n=491) from two cohort studies, the Minority Aging Research Study (MARS) and the Rush Memory and Aging Project (MAP). Participants completed a 32-item questionnaire assessing sleep quality and the possible presence of three sleep disorders (sleep apnea, restless leg syndrome [RLS] and REM behavior disorder [RBD]). Disability was assessed with scales that quantified the ability to perform instrumental activities of daily living (IADL), basic activities of daily living (ADL), and physical mobility activities.
More than half of the participants reported impaired sleep quality (51%), or the possible presence of at least one sleep disorder (57%; sleep apnea 44%, RLS 25% and RBD 7%). Sleep quality was rated poorer in African Americans, those with advancing age and fewer years of education (all P<.05). Only sleep apnea risk was associated with age (P<.02). In logistic regression models adjusted for age, sex, years of education, and race, both sleep quality and disorders were associated with disability (sleep quality with mobility disability (P<.001), sleep apnea risk with mobility disability and IADL disability (all P<.001) and RLS symptoms with mobility disability (P<.01).
Results indicate that self-assessed impaired sleep is common in old age and is associated with disability.
评估自报睡眠质量和可能的睡眠障碍与种族多样化的社区居住老年人残疾之间的关系。
参与者包括来自两项队列研究（少数族裔老龄化研究[MARS]和拉什记忆与老龄化项目[MAP]）的 943 名非痴呆的老年非裔美国人（n=452）和白人（n=491）。参与者完成了一份 32 项的问卷，评估睡眠质量和三种睡眠障碍（睡眠呼吸暂停、不安腿综合征[RLS]和快速眼动睡眠行为障碍[RBD]）的可能存在。残疾用评估进行日常活动的工具能力（IADL）、基本日常生活活动（ADL）和身体活动能力的量表进行评估。
超过一半的参与者报告睡眠质量受损（51%），或至少有一种睡眠障碍（57%；睡眠呼吸暂停 44%，RLS 25%和 RBD 7%）。非裔美国人、年龄较大和受教育年限较少的人（所有 P<.05）睡眠质量评分更差。只有睡眠呼吸暂停风险与年龄相关（P<.02）。在调整年龄、性别、受教育年限和种族的逻辑回归模型中，睡眠质量和障碍都与残疾有关（睡眠质量与移动性残疾相关（P<.001），睡眠呼吸暂停风险与移动性残疾和 IADL 残疾相关（均 P<.001），RLS 症状与移动性残疾相关（P<.01）。
结果表明，自我评估的睡眠障碍在老年中很常见，与残疾有关。
