老年人白天过度嗜睡及相关因素分析

The analaysis of excessive daytime sleepiness and relevant factors in the elderly

目的 探讨白天过度嗜睡 (EDS)在老年人中的发生率及相关因素。 方法 采用国际通用的“Epworth嗜睡量表”(ESS量表 )在 10 0 0例离退休老年人中进行调查 ,收回有效问卷 76 8份 ,回收率为 76 8%,对有效问卷采用多元逐步回归分析方法 ,探讨老年人EDS有关的因素。 结果 老年人ESS量表评分平均值为 (4 2 2± 0 10 )分 ,以ESS评分≥ 8分为临界值 ,老年人EDS的发生率为10 9%,经多元逐步回归分析显示白天困倦、习惯性打鼾、大而不均的鼾声 3个因素与嗜睡评分密切相关 ,回归系数分别为 1 4 5 8、0 5 91、0 5 6 7(P <0 0 5 )。 结论 老年人白天困倦、习惯性打鼾、大而不匀的鼾声可能是独立于老年人年龄、性别、睡眠时间、入睡困难、早醒等因素以外导致老年人白天过度嗜睡的相关因素。

Objective To investigate the prevalence rate and related factors of excessive daytime sleepiness (EDS) in the elderly. Methods Epworth Sleep Scales (ESS) was used to make a randomized questionnaire among the retired elderly. Results 1 000 questionnaires were released and totally 768 qualified answers were returned. The mean score of ESS was 4.22±0.10 and the score ≥8 was used as an abmormal value. The prevlence rate of EDS in the elderly group was 10.9%. Regression analysis was done based on ESS score as dependent variable, and age, sex, duration of sleep, difficulty in falling asleep, early wakeup, daytime sleepiness, habitual snoring and loud unstable snoring as independent variables. It was showed that daytime tiredness(r=1.458, P<0.05), snoring(r=0.591, P<0.05) and the type of snoring(r=0.567 P<0.05) were related factors for elderly EDS. Conclusions The prevalence rate of EDS in the elderly group is 10.9%.Daytime tiredness, habitual and loud snoring are closely related to ESS score and considered the independent risk factors for EDS in the elderly.
