Investing in Sustainable Aging: An Intergenerational Volunteering Model for Health Equity in Taiwan

Abstract Background Taiwan, like many countries, faces rapid population aging with widening gaps in nutrition and social connection. Scalable community health innovations are essential for physical and mental well-being. Guided by WHO's framework, Jia-Yi Facility implemented an intergenerational volunteering model integrating meal delivery and psychosocial support. Methods Since 2016, the Jia-Yi Facility has mobilized and trained university students and retirees as community volunteers. These volunteers delivered tailored nutritious meals twice daily to approximately 150 older adults identified by municipal welfare agencies. They also provided weekly psychosocial check-ins to foster companionship and monitor mental well-being. Unlike conventional service models, leveraging community volunteers improved social cohesion, resource efficiency, and program sustainability. Effectiveness was evaluated through structured surveys and qualitative interviews reviewed by public health experts. Results Over a 12-month period, volunteers delivered approximately 109,500 meals. Survey results showed 93% of recipients reported improved nutritional status and reduced social isolation (p < 0.05). Recipient hospitalization rates decreased by 15% (p < 0.05), and volunteer retention exceeded 85%, underscoring the program's sustainability. Conclusions This cost-effective and replicable model addresses health inequities among older adults by improving nutrition and fostering social connection. Recognized with the 2025 ASSET Sustainability Award - Social Common Good Award in Taiwan, the Jia-Yi Facility initiative offers valuable insights for international aging-in-place strategies and community health innovation. Key messages • Intergenerational volunteer programs effectively address elderly nutrition and social isolation. • Utilizing long-term care facilities enhances sustainable community health engagement.
