| Outline of Final Research Achievements |
The purpose of this study was to examine the impact of occupational participation (engagement in personally meaningful activities) on long-term health and well-being. A total of 498 community-dwelling older adults in Japan were followed for a period of 14 years (originally planned for 12 years but extended by 2 years due to the COVID-19 pandemic).
The results revealed that individuals with a positive occupational participation status (good group) had lower prevalence of chronic conditions (such as cardiovascular diseases and spinal cord disorders) and reduced risks of hospitalization and requiring long-term care compared to those with a negative occupational participation status (poor group) after 14 years. Furthermore, the study also shed light on the types of leisure activities affected by the COVID-19 pandemic and their impact on various aspects of health (e.g., depression, anxiety, sense of purpose (Ikigai), subjective health perception).

| Academic Significance and Societal Importance of the Research Achievements |
本人にとって大切な活動に満足に従事できること（作業参加）は，健康や幸福にとって重要であると従来は経験的に考えられてきたが，その予防医学的根拠は不十分であった．そのため，予防医学で作業参加が不良な状態は軽視されがちであった（例えば，介護予防や社会的な緊急事態時など）．本研究では，地域の高齢者約500名を14年間に渡って追跡することで，作業参加の状態は，慢性疾患や入院・要介護状態等のリスクを低下させることを明らかにした．本研究成果は，作業参加（「活動や参加」）の健康や幸福に対する重要性を科学的根拠を伴って再認識させるものである．今後のより適切な予防医学や保健医療行政の一助となることが期待される．
