The results of the present study revealed that the physiological responses to the external Zeitgebers or synchronizers in the disabled elderly persons decreased and the frequency of internal desynchronization of circadian rhythm increased. For this reson, the level of activity of daily living tended to decrease in the disabled elderly persons. The analyzes of continuously monitored data of blood pressure and heart rate supported this hypothesis. The stimulation of social contacts and the exposure to intense sunlight during daytime are thought to be effective measures to prevent the internal desynchronization of circadian rhythm in the disabled elderly. It remains to be further investigated in the future how to plan a schedule of social contacts and sunlight exposure. It has been shown by the selfcompleted questionnaire on life rhythm and health for the active elderly persons that the level of activity of daily living was closely associated with pattern of life rhythm such as morningnes … More s-eveningness preference and the intensity of social network, which suggested that social support for strengthening the social network was useful for intensifving the synchronization of circadian rhythm of body functions. It has been observed in the present study that the frequency of internal desynchronization of circadian rhythm was more frequent in the elderly persons than in the younger persons. The circadian amplitude of heart rate rhythm estimated by the continuous recording method reflected the level of physical activity of the elderly persons. This easily measured physiological variable serves as a good indicator for evaluation the activity of daily living in the elderly. In conclusion, it has been clarified that the synchronization of circadian rhythm plays an important role in the elevation of activity of daily living in the disabled elderly, which should be considered in the determination of quantity and quality of social contacts provided by the home care of the disabled elderly in the piblic health services.

本研究结果表明，失能老年人对外部节律或同步器的生理反应降低，昼夜节律内部去同步化频率增加。因此，失能老年人的日常生活活动水平有下降的趋势。对连续监测的血压和心率数据的分析支持了这一假设。社会交往的刺激和白天强烈的阳光照射被认为是防止残疾老年人昼夜节律内部失步的有效措施。如何规划好社交活动和阳光暴晒的日程，还有待今后进一步研究。自编的老年人生活节奏与健康调查问卷显示，日常生活活动水平与晨间…等生活节律模式密切相关更多的S-夜晚偏好和社会网络的强度，这表明社会支持加强社会网络有助于强化身体机能昼夜节律的同步性。在本研究中观察到，昼夜节律的内部去同步频率在老年人比年轻人更频繁。连续记录法估计的心率节律昼夜幅度反映了老年人的体力活动水平。这一易于测量的生理变量是评价老年人日常生活能力的良好指标。最后，阐明了昼夜节律的同步性对失能老人日常生活能力的提高起着重要作用，在确定失能老人居家照料在公共卫生服务中提供的社会交往的数量和质量时，应考虑到这一点。较少
