We conducted a 19-site cross-sectional study. We registered 467 dysphagic patients aged \u2265 20 years. Sarcopenic dysphagia was assessed using a reliable and validated diagnostic algorithm. BMI was assessed using the area under the curve (AUC) in the receiver operating characteristic analysis to determine diagnostic accuracy for sarcopenic dysphagia. The study included 460 patients (median age, 83.0 years (76.0\u201388.0); men, 49.8%). The median BMI was 19.9 (17.3\u201322.6) kg\/m2. Two hundred eighty-four (61.7%) patients had sarcopenic dysphagia. The AUC for sarcopenic dysphagia was 0.60\u20130.62 in the overall patients, male, female, and patients aged \u2265 65 years The BMI cut-off value for sarcopenic dysphagia diagnosis was 20.1 kg\/m2 in the overall patients (sensitivity, 58.1%; specificity, 60.2%) and patients aged \u2265 65 years (sensitivity, 59.8%; specificity, 61.8%). Conclusion: Although the AUC, sensitivity and specificity of BMI for sarcopenic dysphagia diagnosis was approximately 0.6, BMI &lt; 20.0 kg\/m2 might be a predictor for sarcopenic dysphagia. In clinical settings, if patients with dysphagia have a BMI &lt; 20.0 kg\/m2, then sarcopenic dysphagia should be suspected as early as possible after admission.<\/jats:p>","DOI":"10.3390\/nu14214494","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T05:11:33Z","timestamp":1666761093000},"page":"4494","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Sensitivity and Specificity of Body Mass Index for Sarcopenic Dysphagia Diagnosis among Patients with Dysphagia: A Multi-Center Cross-Sectional Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1753-4450","authenticated-orcid":false,"given":"Shintaro","family":"Togashi","sequence":"first","affiliation":[{"name":"Department of Nursing Care, Sendai Kosei Hospital, Sendai 980-0873, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0364-0818","authenticated-orcid":false,"given":"Hidetaka","family":"Wakabayashi","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Tokyo Women\u2019s Medical University Hospital, Tokyo 162-8666, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hironori","family":"Ohinata","sequence":"additional","affiliation":[{"name":"Department of Nursing, International University of Health and Welfare, Chiba 286-8686, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6726-8605","authenticated-orcid":false,"given":"Shinta","family":"Nishioka","sequence":"additional","affiliation":[{"name":"Department of Clinical Nutrition and Food Service, Nagasaki Rehabilitation Hospital, Nagasaki 850-0854, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3261-8721","authenticated-orcid":false,"given":"Yoji","family":"Kokura","sequence":"additional","affiliation":[{"name":"Department of Nutritional Management, Keiju Hatogaoka Integrated Facility for Medical and Long-Term Care, Hosu 927-0023, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3274-3952","authenticated-orcid":false,"given":"Ryo","family":"Momosaki","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Medicine, Mie University Graduate School of Medicine, Tsu 514-8507, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"259","DOI":"10.1038\/nrgastro.2015.49","article-title":"Dysphagia: Current Reality and Scope of the Problem","volume":"12","author":"Shaker","year":"2015","journal-title":"Nat.
