The purpose of this study was to investigate the associations of oral health-related quality of life (OHRQoL) with age and oral health, including oral and swallowing function, among psychiatric inpatients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The subjects included 165 psychiatric inpatients in psychiatric hospitals in Japan. The General Oral Health Assessment Index (GOHAI) and the Eating Assessment Tool (EAT-10) were included in the questionnaire survey for the measurement of OHRQoL and the screening of dysphagia. A score\u2009\u2265\u20093 on the EAT-10 was defined as suspected dysphagia. Oral examinations and oral diadochokinesis (ODK) measurements for the tongue-lip motor function evaluation were conducted. The inpatients with acute psychiatric symptoms, moderate and severe dementia, and cognitive impairment that affected their ability to communicate and relate their feelings were excluded. A chi-squared test, the Mann\u2013Whitney U test, and linear regression analysis were used for the analysis. The data were analysed at the 5% significance level.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 100 (64.5%) psychiatric inpatients (mean age, 67.3 [SD, 14.5] years, 49% males, and 51% females) participated in this study. The means\u2009\u00b1\u2009SDs for the decayed missing filled teeth (DMFT) index and GOHAI score were 20.6\u2009\u00b1\u20096 and 49.7\u2009\u00b1\u20097.9, respectively. The GOHAI score in the older age group (\u2265\u200965\u00a0years) was significantly lower than that in the younger age group (&lt;\u200965\u00a0years). The mean ODK scores were less than 3 times\/s for all syllables. The percentage of the participants with suspected dysphagia was 45.0%. Tooth loss and suspected dysphagia were significantly associated with low GOHAI scores. The EAT-10 score was significantly correlated with the GOHAI score only after adjusting for age and sex (\u03b2\u2009=\u2009\u2212\u20090.725, 95% CI \u2212\u20090.97, \u2212\u20090.64).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In hospitalized psychiatric patients, impaired oral health in the older subjects was more pronounced compared with that among general adults.

Therefore, oral care for the recovery of occlusal and swallowing functions may be needed to improve OHRQoL among psychiatric patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12903-020-01355-5","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T08:04:06Z","timestamp":1607933046000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Associations of Oral Health-Related Quality of Life with age, oral status, and oral function among psychiatric inpatients in Japan: a cross-sectional study"],"prefix":"10.1186","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5732-7926","authenticated-orcid":false,"given":"Satoru","family":"Haresaku","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuyuko","family":"Nakashima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yayoi","family":"Hara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madoka","family":"Kuroki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hisae","family":"Aoki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiko","family":"Kubota","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Naito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,12,14]]},"reference":[{"key":"1355_CR1","doi-asserted-by":"publisher","first-page":"23","DOI":"10.1017\/S1121189X00001421","volume":"18","author":"RC Kessler","year":"2009","unstructured":"Kessler RC, Aguilar-Gaxiola S, Alonso J, Chatterji S, Lee S, Ormel J, et al.
