Participants with mild disabilities had approximately US$1,177 lower annual care cost

Community gathering places are intended to facilitate exercise and social participation for all residents, irrespective of functional decline status. In turn, they provide a foundation for mutual support within the community and act as a key preventive care strategy to extend healthy life expectancy. These places thus promote healthy aging and contribute to mitigating the increasing medical and long-term care (LTC) costs associated with an aging population. However, existing evidence has been derived mainly from studies of functionally independent older adults, leaving a data gap regarding the effects this may have on those already in functional decline.

Noticing this disparity, Associate Professor Kazuki Uemura’s research team at Osaka Metropolitan University’s Graduate School of Rehabilitation Science investigated the association between participation in community gathering places and subsequent long-term care costs among functionally independent older adults and those requiring support or exhibiting mild functional decline. Using the National Health Insurance database known as the Kokuho Database from Toyonaka City, the researchers analyzed data from 9,489 adults aged 75 years and older with and without Long-Term Care Insurance (LTCI) certifications. The team compared LTC costs over a two-year follow-up period between 428 participants and 9,061 non-participants in community gathering places. 

The results indicated that, among older adults requiring support or exhibiting mild functional decline, the estimated average monthly LTC cost was US$98.1 lower for participants than for non-participants, indicating a potential annual reduction of approximately US$1,177. In contrast, no statistically significant difference was observed among functionally independent older adults without LTCI certification.

“Our findings suggest that community gathering places are not merely venues for exercise. They may function as valuable community resources that influence patterns of long-term care service utilization among older adults. Further research involving larger populations and longer follow-up periods is needed to validate these findings. Ultimately, this line of research may contribute to the optimization of municipal preventive care strategies and support evidence-based policymaking in aging societies,” said Professor Uemura.

The findings were published in the Journal of the American Medical Directors Association.
