养老机构认知症伴睡眠障碍老年人睡眠状况的评估

Evaluation of sleep status of the elderly with cognitive disorders and sleep disorders

目的:探讨养老机构认知症伴睡眠障碍老年人睡眠状况。方法:采取方便抽样法选取河北省3家养老机构138名老年人,使用匹斯堡睡眠质量量表(PSQI)、睡眠日志(SD)及便携式移动睡眠记录仪(ACT)评估老人近1个月睡眠状况,比较3种评估方法的差异。结果:养老机构认知症伴睡眠障碍老年人睡眠较差;随认知能力下降,老人自我准确评估睡眠能力下降,自评和客观实际差异有统计学意义(P<0.01)。结论:ACT受外界因素影响较小;PSQI和SD与老年人的认知状况具有较强的负相关;认知症老年人睡眠评估应该兼顾自我评估和客观评估两种方式,以提高评估的准确性。

Objective： To investigate the sleep status of the elderly with cognitive disorders and sleep disorders. Methods ： A total of 138 elderly people from three elderly care institutions in Hebei Province were selected by convenient sampling method. The Pittsburgh sleep quality index （PSQI） , the sleep diary （SD） and the actigraphy （ACT） were used to evaluate the sleep status of the elderly for nearly one month and compare the differences between the three as-sessment methods. Results ： The sleep status of the elderly with cognitive disorders and sleep disorders in elderly care institutions was poor. With the de-crease of cognitive ability, the self - assessment of sleep status of the elderly decreased. There was a significant difference in self - assessment and objective fact（ P 〈 0. 01）. Conclusion ： ACT was less affected by external factors. PSQI and SD had a strong negative correlation with the cognitive status of the elder-ly. Sleep assessment of the elderly with cognitive disorders should take into account the self - assessment and objective assessment of two ways to improve the accuracy of the assessment.
