A TRIAL OF EEG SLEEP PATTERN ANALYSIS IN THE OLD FOR COMMUNITY HEALTH CARE PLANNING

对5名老年人进行连续3次通宵多导睡眠监测、主观睡眠研究和生活方式研究。1.睡眠障碍老年人的总睡眠时间和睡眠效率低于非睡眠障碍老年人。睡眠障碍以睡眠潜伏期延长型和ST_4、SREM(%)减低型为主。与青壮年相比，入睡后觉醒总次数增加不明显，但睡眠过渡次数和入睡后觉醒时间增加。回归分析显示，平均睡眠深度与睡眠时间呈负相关，相关系数为-0.629(p&lt；0.01)。睡眠障碍老年人与非睡眠障碍老年人主观睡眠差异无统计学意义。睡眠质量差的老年人和入睡障碍的老年人第二天躺在床上的时间比其他人长。相比之下，其他人在接下来的一天里聊天、阅读和散步等。这些结果表明，非睡眠障碍老年人比睡眠障碍老年人有更高的日常活动量。

Three consecutive all-nights polysomnography,subjective sleep study and life-style study were performed on 5 old persons. And we studied the relationship between the EEG sleep patterns and the daily activities in the present investigation,1. Total sleep times and sleep efficiencies among sleep-disturbed old persons were lower than that among non sleep-disturbed old persons. And the sleep-disturbed cases were consist of the sleep latency prolonged type and the St.4 and SREM(%) decreased type.2. As compared with the reports in relation to young adults,the total number of awaking after sleep onset did not increase remarkably,but the transitional number of sleep stages and the time of wake after sleep onset increased in the present investigation. Mean sleep depth and sleep time had a correlation in regression analysis,and a correlation coefficient was -0.629(p<0.01).3. Subjective sleep showed no significant difference between sleep-disturbed old persons and non sleep-disturbed old persons.4. Sound sleep-disturbed old persons and sleep onset disturbed old persons lay down on the bed for longer time than the others in the next daytime. In contrast,the others spent the next daytime with talking,reading and walking and so on. These results suggest that non sleep-disturbed old persons have higher daily activity than sleep-disturbed old persons.
