Profile

This research theme aims to develop an intervention for individuals unwilling to participate in preventive activities for dependent life despite being assessed as having a high-risk of frailty. In our survey that investigated older residents residing in urban areas, 51.9% were deficient in social interaction, although only 5.8% of respondents had impairment of IADL (Instrumental Activities of Daily Living). We speculated that the deficient in social interaction is caused by their lack of a role to fulfill in their local areas. Thus, our research theme focuses on preventive activity starting from social interaction (creating roles).
Promotion of social interaction is based on “social cohesion and trust”, however, if attendants could not respond to their roles, that may facilitates “informal social control” and isolation, and it comes an adverse effect. Therefore, we aim to intensively study an expert support system that can avoid such an adverse effect.
We will develop a preventive program in which experts and residents can solve local issues together using the “community as partner” model. We also intend to develop a training program that enables residents to provide service to users in the day-service centers as sub-staff. We will verify the efficacy of those programs through implementing action research or comparing to other researches.
Furthermore, we will develop in-home preventive evaluation methods. Using ICT (Information and Communication Technology), we will develop simple evaluation of walking and cognitive function. We expect that these devices will promote the understanding of preventive activities even in the younger generation.

Using a longitudinal study design, we also explore the correlation between economic and social disparity on the health of elderly living in metropolitan areas. With rapid social structure changes likely in the near future, we believe it will affect the health of seniors, particularly those who have difficulty adapting to change. The main target of this study are urban dwelling seniors who have dropped out of previous studies. These seniors demonstrate difficulty adjusting to changes in their health and living environment, putting them at higher risk of social isolation. Through cooperation with local governments, we can determine use-patterns of social resources - such as medical treatment, care, welfare, and community activities- by city-dwelling seniors, determining those who are at high risk for becoming socially isolated.
This research is conducted in close cooperation with our institute and hospital section. By cooperating with local governments in Tokyo, we will not only be able to present the issues of isolated elderly, but additionally develop a new model of local community services that address this need. We will furthermore collaborate with private enterprises and groups constructing of a social support network for urban dwelling elderly to develop an implementation system for action research.
