ABSTRACT
<b>Purpose</b> : The purpose of the present study was to examine the relationship between respiratory function and ADL/QOL among community-dwelling elderly requiring support or care.<br><b>Methods</b> : The study included 87 elderly aged ≥65 years who were certified to require support (yousienn)or care (youkaigo)level 1-3 and who used day care at a rehabilitation center. We evaluated their respiratory, mental, physical, and swallowing functions. ADL, IADL, and QOL were estimated using a questionnaire. Spearman's rank correlation test and multiple regression analysis were used to examine correlations of the functions with ADL/QOL.<br><b>Results</b> : Respiratory, physical, and swallowing functions showed statistically significant correlations with ADL/IADL/QOL. Multiple regression analysis showed that forced expiratory volume in 1 second and swallowing function were related to ADL, IADL, and QOL (SF8body & mental).<br><b>Conclusion</b> : ADL and QOL were associated with respiratory function in elderly subjects requiring support or care. Our data suggested that pulmonary rehabilitation to enhance respiratory and swallowing functions in elderly requiring support or care may improve their ADL and QOL.
