It is important for the elderly to maintain their skeletal muscle mass, which in turn helps to maintain physical functions. This study aimed to clarify factors related to skeletal muscle mass maintenance. Home-bound elderly (94 men and 216 women), at least 75 years of age, attending a day-care center in Tokyo, were enrolled in this study. Dentists specializing in dysphagia rehabilitation evaluated skeletal muscle mass, occlusal status and swallowing function. Physical function, cognitive function and nutritional status were also evaluated by interviewing caregivers. Correlations of skeletal muscle mass with various factors were determined in each gender group. Multiple regression analysis revealed that skeletal muscle mass was significantly related to nutritional status in both men and women. In men, there was a significant difference in skeletal muscle mass between those with and without occlusion of the natural teeth. Our results suggest that dental treatments and dentures would be useful for maintaining skeletal muscle mass, especially in men.
