BACKGROUND
Hospitalized older intensive care unit (ICU) survivors are often inactive and experience sleep disturbances.
OBJECTIVE
We explored associations between post-ICU activity, sleep/rest, and motor function among hospitalized older ICU survivors.
METHODS
We enrolled 30 older ICU survivors, ages 65 and older, within 24-48 h of ICU discharge. Actigraphy measured post-ICU activity and sleep/rest. Selected measures from the National Institutes of Health Toolbox Motor Battery assessed grip strength and dexterity. Multivariate regression examined associations between post-ICU activity, sleep/rest, and motor function, adjusting for covariates.
RESULTS
Lower daytime activity (β = 0.258, p = .035) and greater daytime sleep/rest (β = -0.295, p = .022) were associated with worse grip strength. Lower daytime activity (β = -0.376, p = .037) and greater daytime sleep/rest (β = 0.409, p = .026) were associated with worse dexterity.
CONCLUSION
Post-ICU inactivity and prolonged rest periods are associated with worse motor function in hospitalized older ICU survivors.
背景
住院老年重症监护病房（ICU）幸存者通常活动量少且存在睡眠障碍。
目的
我们探究了 ICU 出院后住院老年 ICU 幸存者的活动量、睡眠/休息和运动功能之间的关联。
方法
我们招募了 30 名年龄在 65 岁及以上的 ICU 幸存者，在 ICU 出院后 24-48 小时内进行了活动监测和睡眠/休息评估。使用加速度计测量 ICU 后活动量和睡眠/休息情况。采用 NIH 工具包运动电池的选定指标评估握力和灵巧度。多变量回归分析调整协变量后 ICU 后活动量、睡眠/休息与运动功能之间的关系。
结果
白天活动量较低（β=0.258，p=0.035）和白天睡眠时间/休息时间较长（β=-0.295，p=0.022）与握力下降相关。白天活动量较低（β=-0.376，p=0.037）和白天睡眠时间/休息时间较长（β=0.409，p=0.026）与灵巧度下降相关。
结论
ICU 后活动量减少和休息时间延长与住院老年 ICU 幸存者的运动功能下降有关。
