Relationship between swallowing function and the skeletal muscle mass of older adults requiring long-term care

Aim The present study investigated the risk factors for dysphagia among older adults who require long‐term care, and also examined their systemic decrease in skeletal muscle mass. Methods We evaluated 399 people who required long‐term care and who were residing in Omori town, Yokote city, Akita prefecture, Japan. We then analyzed data from 255 participants who had complete information available regarding their sex, age, case history (stroke, Parkinson's disease and dementia), Barthel Index, Skeletal Muscle Mass Index, oral function test and modified water swallowing test results. Participants' water swallowing test results were used to create groups with good or poor swallowing function, and a univariate analysis was carried out for each parameter. Parameters with a P‐value of
