OBJECTIVES
Evaluate differences in sleep characteristics between older adults with and without mild Alzheimer's disease using waist-worn actigraphy monitors.
METHODS
Actigraph GT3X+ monitors and self-reported sleep and activity logs were used for one week and compared between older adults (N = 85) with (n = 35) and without Alzheimer's disease (n = 51).
RESULTS
Participants with Alzheimer's disease had greater total sleep time and spent more time in bed than nonimpaired older adults. Estimates for sleep efficiency and total sleep time for the total sample were elevated compared to previous studies of wrist-worn devices in similar populations, while estimates of sleep onset latency and wake after sleep onset for the total sample were lower.
CONCLUSIONS
Actigraphy-based sleep studies in older adults with Alzheimer's disease should consider discrepancies between objective and subjective estimates of sleep and monitor placement to maximize the ability to measure both activity and sleep.
目的
使用腰部佩戴的活动记录仪评估患有和未患有轻度阿尔茨海默病的老年人在睡眠特征方面的差异。
方法
使用Actigraph GT3X+记录仪以及自我报告的睡眠和活动日志，为期一周，并在患有（n = 35）和未患有阿尔茨海默病（n = 51）的老年人（N = 85）之间进行比较。
结果
与未受损的老年人相比，患有阿尔茨海默病的参与者总睡眠时间更长，卧床时间更多。与之前在类似人群中使用腕部佩戴设备的研究相比，总样本的睡眠效率和总睡眠时间估计值有所提高，而总样本的入睡潜伏期和睡眠中觉醒时间估计值较低。
结论
在患有阿尔茨海默病的老年人中，基于活动记录仪的睡眠研究应考虑睡眠客观和主观估计之间的差异以及监测器的放置位置，以最大限度地提高测量活动和睡眠的能力。
