Outline of Final Research Achievements	This study aimed to determine the effectiveness of nutritional and dietary guidance interventions based on oral function and nutritional assessments, and whether this guidance could lead to improvements in body composition. However, while we considered recording menus and photographing meals so that registered dietitians could provide nutritional guidance, it became difficult to secure registered dietitians to provide the guidance due to COVID-19 infection prevention measures, so we investigated the relationship between body composition, which is thought to represent nutritional status, and physical and oral function. A total of 246 people were tested for oral function and sarcopenia, and it was found that tongue pressure was most closely related to the presence or absence of sarcopenia. It was shown that tongue pressure measurement, one of the oral function evaluation items, can predict physical muscle mass and may contribute to the prevention of sarcopenia.

Academic Significance and Societal Importance of the Research Achievements	多くの研究から歯科治療単体のみでは食の行動変容を伴う栄養摂取の改善は困難であるとされており，口腔機能の状況に合わせた栄養摂取ならびに栄養食指導が必要と考えられる。これらの栄養指導についての研究予定であったが，管理栄養士による栄養指導が困難な社会状況であったため，本研究では，栄養状態を表すと思われる体組成のなかで四肢骨格筋量に焦点を当て，筋肉量等の身体機能等と口腔機能との関連を検討した。舌圧とサルコペニアの関連があったことから，歯科医院での口腔機能検査によって，全身状態の予想やサルコペニア等の栄養に影響される疾患の予防に繋げられる社会医学的意義が示された。
