研究目标：本研究探讨了老年妇女睡眠障碍和日间功能较差之间的关系。设计：观察性研究。参与者：2，889名妇女，平均年龄83.5岁，参加了2002-2004年骨质疏松性骨折研究的检查。干预措施：N/A测量和结果：参与者佩戴活动记录仪的平均+/- SD为4.1 +/- 0.83 24小时。体动仪测量的睡眠变量为总睡眠时间和入睡后清醒时间以及夜间和日间小睡行为。神经肌肉性能测量包括步态速度，椅子的立场，和握力。功能限制被评估为自我报告的6项工具性日常生活活动（IADL）中的一项或多项困难。在完全调整的多变量模型中，睡眠时间= 7.5小时的女性完成5个椅子站立所需的时间比睡眠时间6.8-7.5小时的女性多4.1%。睡眠开始后觉醒更高（>= 1.6小时，
Study Objectives: This study examined the association between disturbed sleep and poorer daytime function in older women.Design: Observational study.Participants: 2,889 women, mean age 83.5 years, participating in the 2002-2004 examination of the Study of Osteoporotic Fractures.Interventions: N/AMeasurements and Results: Participants wore actigraphs for an average +/- SD of 4.1 +/- 0.83 24-hour periods. Actigraphy measured sleep variables were total sleep time and hours awake after sleep onset during the night and daytime napping behavior. Neuromuscular performance measurements included gait speed, chair stands, and grip strength. Functional limitations were assessed as self-reported difficulty with one or more of 6 instrumental activities of daily living (IADL). In fully adjusted, multivariable models, women who slept = 7.5 hours took 4.1 % longer to complete 5 chair stands than those who slept 6.8-7.5 hours. With higher wake after sleep onset ( >= 1.6 hours compared to
