旨在确定客观测量的睡眠质量是否可以预测老年女性五年工具性日常生活活动 (IADL) 损伤以及握力和步速下降。前瞻性队列 参与者的家、骨质疏松性骨折研究地点 817 名女性（基线平均年龄 82.4 岁） 参与者在基线时完成了 4.1 ±0.7 晚的腕部活动记录，并在基线和五年随访时测量 IADL 损伤、握力和步态速度。经过五年的随访，大约 41% 的参与者出现了 ≥1 IADL 的事件损伤。总睡眠时间最短的四分位数女性发生 IADL 损伤的几率比睡眠时间最长的女性高 93%（调整后优势比 (AOR) = 1.93，95% 置信区间 (CI) 1.25、2.97）。同样，睡眠效率最低的四分位女性比睡眠效率最高的女性高 65%（AOR = 1.65，95% CI 1.06，2.57）。与总睡眠时间最长的女性相比，总睡眠时间最短四分位的女性握力下降的几率是女性的两倍（AOR = 1.97，95% CI 1.17，3.32）。最后，入睡后觉醒次数最多且睡眠效率最低的四分位女性的握力下降几率比入睡后觉醒次数最少的女性（AOR = 1.90，95% CI 1.11，3.24）和睡眠效率（AOR = 1.92，95% CI 1.12，3.29）高约 90%。研究结果表明，睡眠时间较短、入睡后觉醒次数较多以及睡眠效率较低是老年女性功能或身体衰退的危险因素。
To determine whether objectively measured sleep quality predicts five-year incident instrumental activities of daily living (IADL) impairment and decline in grip strength and gait speed in older women. Prospective cohort Participants’ homes, Study of Osteoporotic Fractures sites 817 women (mean 82.4 years at baseline) Participants completed 4.1 ±0.7 nights of wrist actigraphy at baseline, and measures of IADL impairment, grip strength, and gait speed at baseline and five-year follow-up. After five years of follow-up, approximately 41% of participants had incident impairment in ≥1 IADL. The quartile of women with the shortest total sleep time had a 93% greater odds of incident IADL impairment than the longest sleepers (adjusted odds ratio (AOR) = 1.93, 95% confidence interval (CI) 1.25, 2.97). Similarly, the quartile of women with the lowest sleep efficiency had a 65% greater odds of impairment than those with the highest (AOR = 1.65, 95% CI 1.06, 2.57). Women in the shortest total sleep time quartile had double the odds of declining grip strength, compared to those with the longest total sleep time (AOR = 1.97, 95% CI 1.17, 3.32). Finally, women in the quartiles with the most wake after sleep onset and the lowest sleep efficiency had an approximately 90% greater odds of grip strength decline than those with the least wake after sleep onset (AOR = 1.90, 95% CI 1.11, 3.24) and sleep efficiency (AOR = 1.92, 95% CI 1.12, 3.29). Findings indicate that shorter sleep duration, greater wake after sleep onset, and lower sleep efficiency are risk factors for functional or physical decline in older women.
