Association Between Oral Hypofunction, Sarcopenia and Social Frailty in Community-dwelling Older Adults

Previous studies have provided a preliminary understanding of the likelihood of sarcopenia and the prevalence of sarcopenia in the elderly in the community. due to the interaction between physiological and social factors, this study aims to conduct a correlation study on muscle mass, oral function and social frailty in the elderly living in the community. This study，the Makizako social frailty screening index questionnaire and the Tilburg Frailty Indicator will be used to assess the social frailty status of the study participants. Correlation analysis with sarcopenia and oral dysfunction was also conducted to better understand the interaction between nutrition, physiology, and social connection in the elderly, which will be helpful for formulating relevant policies and promoting healthy aging in the future in extremely elderly countries.
