A self-administered questionnaire survey and a clinical periodontal examination were conducted from 2013 through 2016. The self-reported periodontitis questions included 3 sociodemographic, 3 health, and 5 periodontal health\u2013related items. Based on the clinical case definition of periodontitis, 26.5% of participants were found to be periodontally healthy, 2.7% had mild periodontitis, 55.2% moderate periodontitis, and 15.6% severe periodontitis. No single self-reported question demonstrated satisfactory validity in predicting the presence or absence of periodontitis. The predictive ability in mild and\/or moderate periodontitis was poor even after combining multiple sociodemographic, health, and periodontal health-related questions. In severe periodontitis, the model including age, sex, education level, smoking status, diabetes history, body mass index, informed by a dentist, gingival bleeding, calculus deposit, and tooth mobility, presented moderate predictive performance (C-statistic: 0.676, sensitivity: 65.2%, and specificity: 61.1%). An age-stratified analysis on severe periodontitis showed that sensitivity was higher, and specificity was lower in older age group (60-75 years) than younger age group (40-59 years). Further refinement of questions in the self-report is required to increase the accuracy of the prediction of clinical periodontitis.<\/jats:p>","DOI":"10.1177\/1010539520944721","type":"journal-article","created":{"date-parts":[[2020,8,1]],"date-time":"2020-08-01T07:14:27Z","timestamp":1596266067000},"page":"346-353","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Validity of Self-Reported Periodontitis in Japanese Adults: The Japan Public Health Center\u2013Based Prospective Study for the Next-Generation Oral Health Study"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3310-8870","authenticated-orcid":false,"given":"Masayuki","family":"Ueno","sequence":"first","affiliation":[{"name":"Saitama Prefectural University, Koshigaya, Japan"},{"name":"Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taichi","family":"Shimazu","sequence":"additional","affiliation":[{"name":"National Cancer Center, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norie","family":"Sawada","sequence":"additional","affiliation":[{"name":"National Cancer Center, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shoichiro","family":"Tsugane","sequence":"additional","affiliation":[{"name":"National Cancer Center, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoko","family":"Kawaguchi","sequence":"additional","affiliation":[{"name":"Tokyo Medical and Dental University, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,8,1]]},"reference":[{"key":"bibr1-1010539520944721","doi-asserted-by":"publisher","DOI":"10.1177\/1010539510387822"},{"key":"bibr2-1010539520944721","first-page":"A86","volume":"5","author":"Van Minh H","year":"2008","journal-title":"Prev Chronic Dis"},{"key":"bibr3-1010539520944721","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-3797(99)00158-0"},{"key":"bibr4-1010539520944721","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.31.7.1602"},{"key":"bibr5-1010539520944721","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2004.04.005"},{"key":"bibr6-1010539520944721","unstructured":"Ministry of Health, Labour, and Welfare.
