The aim of this paper was to explore the effect of seasonal temperature differences and cold indoor environment in winter on the physical performance of older people living in the community based on a field study. We recruited 162 home-dwelling older people from a rehabilitation facility in the Osaka prefecture, Japan; physical performance data were available from 98/162 (60.5%). At the same time, for some participants, a questionnaire survey and a measurement of the indoor temperature of individual houses were conducted. The analysis showed that there were seasonal trends in the physical performance of older people and that physical performance was worse in the winter compared with the autumn. Furthermore, people living in colder houses had worse physical performance. The findings indicate that keeping the house warm in the winter can help to maintain physical performance.
本文旨在通过一项实地研究，探讨季节性温差和冬季寒冷的室内环境对社区老年人身体机能的影响。我们从日本大阪府的一个康复机构招募了162名居家老年人；其中98人（60.5%）有身体机能数据。同时，对部分参与者进行了问卷调查和各户室内温度测量。分析表明，老年人的身体机能存在季节性趋势，且冬季的身体机能比秋季更差。此外，居住在较冷房屋中的人的身体机能更差。研究结果表明，冬季保持房屋温暖有助于维持身体机能。
