| Outline of Final Research Achievements |
In this study, we investigated the association among masticatory function, dietary intakes and the development of sarcopenia in old-old Japanese. In the result, 83-year-old people whose occlusal force is low at 80 years old didn’t maintain adequate nutrition.
The occlusal force of people who was defined as sarcopenia at 86 years old was significantly lower than other people.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の結果から，高齢者において，口腔機能と栄養摂取，サルコペニア（筋肉量，筋力，身体能力の低下）の発症並びに進行との間に関連が認められることが示唆された．このことから、高齢者においては，身体機能の低下が顕在化する前に，口腔機能を維持するために早期介入を行ことで，一次予防による健康維持を促すことができる可能性があると考えられる．このことは，高齢者のQOLを高めるとともに，医療費の削減など社会的意義は大きい．
