Methods and Material: This study sampled 142 elderly people equal to or older than 65 years old who were using a senior welfare center. The swallowing problem associated quality of life was defined by the swallowing quality-of-life (SWAL-QOL). In order to verify the predictive power of the model, this study compared the predictive power of the Gaussian function with that of a linear algorithm, polynomial algorithm, and a sigmoid algorithm. Results: A total of 33.9% of the subjects decreased in swallowing quality-of-life. The swallowing quality-of-life prediction model for the elderly, based on the SVM, showed both preventive factors and risk factors. Risk factors were denture use, experience of using aspiration in the past one month, being economically inactive, having a mean monthly household income &lt;2 million KRW, being an elementary school graduate or below, female, 75 years old or older, living alone, requiring time for finishing one meal on average \u226415 min or \u226540 min, having depression, stress, and cognitive impairment. Conclusions: It is necessary to monitor the high-risk group constantly in order to maintain the swallowing quality-of-life in the elderly based on the prevention and risk factors associated with the swallowing quality-of-life derived from this prediction model.<\/jats:p>","DOI":"10.3390\/ijerph16214269","type":"journal-article","created":{"date-parts":[[2019,11,4]],"date-time":"2019-11-04T04:13:08Z","timestamp":1572840788000},"page":"4269","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Predicting the Swallow-Related Quality of Life of the Elderly Living in a Local Community Using Support Vector Machine"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3363-390X","authenticated-orcid":false,"given":"Haewon","family":"Byeon","sequence":"first","affiliation":[{"name":"Department of Speech Language Pathology, School of Public Health, Honam University, 417, Eodeung-daero, Gwangsan-gu, Gwangju 62399, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,11,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1007\/s00455-011-9328-2","article-title":"Age and sex differences in orofacial strength","volume":"27","author":"Clark","year":"2011","journal-title":"Dysphagia"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"515","DOI":"10.2147\/CIA.S132637","article-title":"Oral conditions and dysphagia in Japanese, communitydwelling middle-and older-aged adults, independent in daily living","volume":"12","author":"Akinari","year":"2017","journal-title":"Clin.
