Community-based care for healthy ageing: lessons from Japan

Area of Science:

• Gerontology
• Public Health
• Social Medicine

Background:

• Japan faces the world's largest aging population, with over 27% of citizens aged 65 and above.
• Previous long-term care prevention measures (2006) failed due to poor identification of high-risk individuals and low program enrollment.

Purpose of the Study:

• To evaluate the effectiveness of a community-based social participation strategy for long-term care prevention in Japan.
• To analyze the impact of the reformed Long-term Care Insurance Act (2015) on promoting social determinants of health.

Main Methods:

• The study focuses on the "ikoino saron" (gathering salons) initiative, a community-based intervention for individuals over 65.
• These salons are locally managed, low-cost, and held in accessible community spaces, offering social interaction and activities.
• The strategy shifted from a high-risk approach to a population-based model inspired by these salons.

Main Results:

• Participation in "ikoino saron" halved the incidence of long-term care needs.
• A one-third reduction in dementia onset risk was observed among participants.
• Financially vulnerable older adults showed higher participation rates, indicating equitable reach.

Conclusions:

• Community-wide interventions, like "ikoino saron," are crucial for effective long-term care prevention.
• Integrated care strategies should complement high-risk targeting with broad community engagement.
• Social participation is a key factor in mitigating long-term care needs and dementia risk in aging populations.
