In order to detect swallowing disorders early, simple tools are needed to assess aspiration and silent aspiration (<jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content>). To compile a sample of elderly people requiring <jats:styled-content style=\"fixed-case\">LTC<\/jats:styled-content>, and categorise them as having suspected aspiration and\/or <jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content> using simple screening tools. In addition, oral ability, severity of dementia, vital functions and nutritional status were compared in these groups. A total of 393 elderly people in <jats:styled-content style=\"fixed-case\">LTC<\/jats:styled-content> (89 men and 304 women; age ranging from 65 to 100 years) were included in the study. The modified water swallow test, cervical auscultation and cough test were used to assess swallowing function. The participants were categorised as having suspected aspiration and\/or <jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content>, and the following assessments were performed: (i) oral ability (lips function, tongue function, rinsing and gargling ability), (ii) dementia severity, (iii) vital functions and (iv) nutritional status. Suspected aspiration was apparent in 50\u00b75% of patients, of which 24\u00b70% had suspected <jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content>. Those with suspected aspiration showed worsened oral ability, dementia severity, vital functions and nutritional status. Similarly, those with suspected <jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content> showed worsened dementia severity, vital functions and nutritional status. Logistic regression analysis revealed that lip closure, lingual movement and rinsing ability were significantly associated with suspected aspiration. Dementia severity was the best predictor of suspected <jats:styled-content style=\"fixed-case\">SA<\/jats:styled-content>. Simple screening tools can be used to identify suspected aspiration and SA, which may facilitate early detection of aspiration pneumonia or swallowing disorder risk.<\/jats:p>","DOI":"10.1111\/joor.12349","type":"journal-article","created":{"date-parts":[[2015,10,3]],"date-time":"2015-10-03T11:54:37Z","timestamp":1443873277000},"page":"103-110","source":"Crossref","is-referenced-by-count":25,"title":["An examination of factors related to aspiration and silent aspiration in older adults requiring long\u2010term care in rural Japan"],"prefix":"10.1111","volume":"43","author":[{"given":"K.","family":"Sakai","sequence":"first","affiliation":[{"name":"Department of Oral Medicine, Oral and Maxillofacial Surgery Tokyo Dental College Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Hirano","sequence":"additional","affiliation":[{"name":"Tokyo Metropolitan Institute of Gerontology Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Oral Diseases Research National Center for Geriatrics and Gerontology Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Tohara","sequence":"additional","affiliation":[{"name":"Gerodontology and Oral Rehabilitation Department of Gerontology and Gerodontology Graduate School of Medical and Dental Sciences Tokyo Medical and Dental University Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Oral and Maxillofacial Surgery Tokyo Dental College Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Oral and Maxillofacial Surgery Tokyo Dental College Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Katakura","sequence":"additional","affiliation":[{"name":"Department of Oral Medicine, Oral and Maxillofacial Surgery Tokyo Dental College Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,10,3]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Statistical handbook of Japan 2013"},{"key":"e_1_2_8_3_1","unstructured":"Annual Report on the Aging Society: 2012 (Summary).
