Abstract
【purpose】The purpose of this study was to examine the relationship between oral function and health-related quality of life（QOL）among independent community-dwelling older Japanese adults aged 65 years or older．A total of 194 participants were surveyed about age，sex，BMI，basic checklist（oral function），quality of life（QOL; SF-8 Physical，Mental Summary Score and），and Timed Up and Go Test（TUG）．【Methods】Participants were divided into an non-low oral function group and low oral function group and data between the groups were compared．【Results】Logistic regression analysis revealed that the SF-8 physical component summary score（PCS）were found to be variables associated with low oral function．In the logistic analysis，the SF-8 sub-items related to low oral function were extracted as Physical function（PF）．【Conclusions】From the perspective of aspiration risk，the association observed between low oral function and health-related QOL in this study suggests the need to focus on the relationship between eating and low oral function and QOL for independent older adults living in the community．
