STUDY ON DEVELOPMENT OF METHODS FOR INTENSIFYING THE SYNCHRONIZATION OF DAILY BEHAVIORAL RHYTHM IN ORDER TO PROMOTE ACTIVITY AND QUALITY OF SLEEP IN THE ELDERLY

本研究的目的是建立系统的方法来加强日常行为节奏的同步，以促进老年人的活动和睡眠质量。我们的研究成果由以下四部分研究组成。(1)基于遗传背景的生物节律个体间差异研究：通过时间生物学程序记录了口腔温度和握力等生物节律的内部不同步，明确了人类昼夜节律不同步的遗传背景。(2)老年人日常行为节奏的研究，以保持良好的睡眠质量和意识水平：针对居家卒中患者和独立老年人，新开发了老年人日常行为节奏问卷。研究了问卷的信度和效度。测量白天α波的功率谱密度，作为判断清醒程度的客观参数。验证了α波功率谱密度与日常生活活动、日常生活体质之间的显著相关。(3)理化因素同步效应研究：采用问卷调查方式，对高强度日照和进餐时间等问题进行问卷调查，评价理化因素对同步效应的影响。(4)老年人日常行为节奏的社会同步性研究：将社会同步性和社会支持项目纳入问卷，评估社会同步性水平。α波功率谱密度与社会支持呈显著相关。此外，在社区层面上阐明了老年人与儿童的代际交往在日常行为节奏的社会同步中的作用。综上所述，系统的评价老年人日常行为节律的方法是一种新方法，可用于评价老年人的活动和睡眠质量。少

The purpose of the present study is to develop systematic methods for intensifying the synchronization of daily behavioral rhythm in order to promote activity and quality of sleep in the elderly. Our research results were composed of four parts of studies as follows. (1) Study on interindividual differences of biological rhythm based on genetic background : Internal desynchronization of biological rhythms such as oral temperature and grip strength was documented by chronobiological procedures, and we have clarified that there is a genetic background of circadian desynchronism in human. (2) Study on daily behavioral rhythm of the elderly in order to preserve good quality of sleep and consciousness level : A questionnaire on daily behavioral-rhythm of the elderly was newly developed for stroke patients at home and independent elderly. Reliability and validity of the questionnaire were studied. The power spectral density of alpha wave during daytime was measured as objective parameter for … More consciousness level. The significant correlation between power spectral density of alpha wave, activity of daily living, and physical fitness of daily living was verified. (3) Study on synchronization of physical and chemical agents : Questions on high intensity day light and timing of meal were included in a questionnaire, and effects of physical and chemical factors in the synchronization were evaluated. (4) Study on social synchronization of daily behavioral rhythm of the elderly : Items of social synchronization and social support were included in a questionnaire, and the level of social synchronization was evaluated. The significant correlation between power spectral density of alpha wave and social support was obtained. Furthermore, the role of intergeneration communication between the elderly and children in the social synchronization of daily behavioral rhythm was clarified in a community level. In conclusion, systematic approach for evaluating daily behavioral rhythm of the elderly is newly developed, which is useful for evaluating the activity and quality of sleep in the elderly. Less
