| Research Abstract |
The concept of social capital has become popular in the last two decades, as it may contribute to health promotion of older adults. Social capital posits the community characteristics that develops interpersonal ties, trusts, and the norm of reciprocity. To understand the dynamisms of the association between social capital and health, the network analysis developed in the field of sociometry may be useful in the field of public health research. The aim of this study was to understand the feasibility and challenges of the application of network analysis on public health research and investigated the interpersonal exchange and contagion of health and health resources within and between groups in a community. We conducted a mailed survey on health and social relationships for all older residents over 600 people in a rural town in Yamanashi Prefecture, Japan, where the traditional financial self-help group activity called “mujin” has still been actively operated. We further gathered nforma

tion on detailed information of name generators for mujin memberships from the study participants who answered that they had participated in one of more mujin activities, using a snowball survey technique. We succeeded in capturing most of mujin groups in the town. We found that persons who participated in mujin actively with a positive attitude were less likely to develop functional disability than nonparticipants of mujin independent of other potential confounding factors. However, those who participated in mujin groups, whose primary purpose was financing,were linked to rather increased risks for functional decline. With this study we found that the network analytic data can be gathered and useful in the setting of public health research, and some challenges were also identified. Further studies would be needed to understand the mechanisms of those positive and negative impacts of mujin on health in terms of the network dynamics within group members, which will be done in our next5-year research projects.
