A study of physiological polymorphism of the biological rhythm in homebound elderly living alone and improvement of their Quality of Life

1)居家老年人昼夜节律异常比例明显高于非居家老年人。在与独居或与他人共同生活相关的分析中，独居老年人（独居组）的昼夜节律异常比例明显高于与他人共同生活的老年人（合住组）。2)在家组和非在家组均存在两种类型的昼夜节律异常（昼夜振幅降低型和昼夜无界限型）。在独居组和合住组中，都发现了相同的类型。3)居家老人的活动量和光照量均小于非居家老人，表明活动量和户外活动频率的减少可能与昼夜节律异常比例的升高有关。独居组的活动量和光照量比合住组的要小，这表明独居老人的活动往往局限于他们家中或周围的一个狭窄区域。4)居家老人的日常生活生物社会节律同步得分显著低于非居家老人。独居组的得分明显低于合住组。其中，在家组和独居组的社会同步得分特别低。5)在日常生活活动的独立程度上，居家组与非居家组无显著差异。此外，两组在日常生活满意度和有无兴趣爱好方面也没有显著差异。在独居组和合住组之间也发现了同样的结果。少

1)The proportion of circadian rhythm abnormalities was significantly higher in the homebound elderly than in the non-homebound elderly. Analysis in relation to living alone or with someone, the proportion of circadian rhythm abnormalities was significantly higher in elderly living alone (the living-alone group) than in elderly living with someone (the shared-living group).2)In both the homebound group and the non-homebound group, two types of circadian rhythm abnormalities (the decreased-circadian-amplitude type and the no-boundary-between -day-and-night type) were recognized. In both the living-alone group and the shared-living group, the same types were recognized.3)The amount of activity and exposure to light were smaller in the homebound elderly than in the non-homebound elderly, suggesting that the decreases in activity and in the frequency of going outdoors was probably associated with an elevated proportion of circadian rhythm abnormalities. The amount of activity and exposure t … More o light were smaller in the living-alone group than in the shared-living group, suggesting that the activities of elderly living alone tended to be confined to a narrow area in and around their homes.4)The biosocial rhythm synchronization score, as rated by a questionnaire designed to determine the biosocial rhythm of daily living, was significantly lower in the homebound elderly than in the non-homebound elderly. Its score was significantly lower in the living-alone group than in the shared-living group. Among others, the social synchronization score was particularly low in the homebound group and living-alone group.5)In terms of the degree of independence in the activities of daily living, there was no marked difference between the homebound group and the non-homebound group. Furthermore, there was also no marked difference between the two groups in the degree of satisfaction with daily living or the presence/absence of hobbies. The same results were recognized between the living-alone group and the shared-living group. Less
