Development and verification of community development index for improving functioning of aged people in rural districts (third report): data collection and analysis system on social mutual aid are desired for community development for elderly persons living in rural districts.

Objective: The author conducted a survey on social mutual aid and the social stimulative effect of older adults living in a rural district, and compared young old and old-old persons to clarify the roles of public health nurses in promoting community development.

Materials and methods: A cross-sectional study based on Andersen's Behavioral Model of Health Care Utilization was conducted with 2,500 residents aged 65 years or older of City A in Akita Prefecture. The study was conducted from April 8 to May 15, 2017. Participants were administered a questionnaire containing items on "social mutual aid in the rural district". Responses were recorded on a Likert scale.

Results: As a result of factor analysis, the following four factors were extracted; [Blessing of a rural district and mutual help and assistance unique to a rural district], [Closeness of healthcare welfare service and family doctors in conjunction with their own health], [Decline of culture and community unique to rural districts accompanied by depopulation] and [Closeness of the town where they live]. Differences were observed in the closeness of social mutual aid and local societal stimulative effects, even between generations of old and old-old persons. In young-old persons, a negative correlation was observed between [Closeness of the town where they live] and other factors. In old-old persons, a negative correlation was found between [Decline of culture and community unique to rural districts accompanied by depopulation] and other factors.

Conclusion: Since not only individual health indices but also local social mutual aid, which relates to individuals' influence on the construction of a Community-based Integrated Care System in a rural district, the author posits that a data collection and analysis system on social mutual aid would be beneficial for community development for older adults living in rural districts.
