| Outline of Final Research Achievements |
The aim of this study is to clarify the effects of living environment on frail factor with multi-level modeling based on multi-temporal repeated measures.
1)Results of multi-level analysis revealed that living room temperature were associated with grip strength and sedentary behavior, nocturia and hypertension, regardless of short-term or long-term exposure. Therefore, indoor thermal environment has direct effects and indirect effects through muscle weakness and cardiovascular disease on Frailty.
2)Logistic regression analysis showed that lack of a third place was positively associated with risk of shut-in behavior, social isolation, and needing long-term care/support. In addition, multi-level logistic regression analysis revealed that living in a neighborhood with a higher perceived flower bed was positively associated with having third place.

| Academic Significance and Societal Importance of the Research Achievements |
超高齢化社会を迎える我が国には、健康長寿延伸という避けられない命題がある。その点から、人々が日常を過ごす住環境に潜む虚弱リスクを明らかにし、個人の行動変容に依存しない環境改善を果たすことで、人々の健康寿命延伸とQOL向上を実現することが重要と考えられる。本研究では、建築環境工学をベースとしながらも、運動疫学や老年医学で重要とされる虚弱指標に着目し、近年、医学分野で必須とされる多変量解析手法であるマルチレベル分析を実施することで、その関係性を明らかにしたことに学術的意義がある。健康という国民の関心を呼ぶテーマから、寒冷環境という見過ごされてきた国民課題を示唆する社会的意義もあると考えられる。
