It was based on the 13th Korea Youth Risk Behavior Web-Based Survey (2017). From 64,991 participants (aged 13\u201318 years), the final participation rate in the survey was 95.8% (62,276 participants; 31,624 boys and 30,652 girls). A complex sample logistic regression was performed to identify the relationship between insufficient sleep and halitosis, after adjusting for all covariates. In Model II for estimating the adjusted odds ratio (AOR) for general characteristics, students who answered \u201cnot at all sufficient\u201d, indicating insufficient sleep, were at higher risk of bad breath than those who answered \u201ccompletely sufficient\u201d (AOR = 2.09, 95% confidence interval, CI = 1.91\u20132.30). In Model III, for estimating the AOR adjusted for all covariates, students who answered \u201cnot at all sufficient\u201d, indicating insufficient sleep, were at higher risk of bad breath than those who answered \u201ccompletely sufficient\u201d (AOR = 1.47, 95% CI = 1.33\u20131.83). It is necessary for families and schools to have health education lessons that recognize insufficient sleep among adolescents may be a cause of bad breath and therefore optimal sleeping habits and oral health behaviors should be promoted.<\/jats:p>","DOI":"10.3390\/ijerph17197230","type":"journal-article","created":{"date-parts":[[2020,10,3]],"date-time":"2020-10-03T07:22:16Z","timestamp":1601709736000},"page":"7230","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Relationship between Insufficient Sleep and Bad Breath in Korean Adolescent Population"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7690-6314","authenticated-orcid":false,"given":"Kyung-Yi","family":"Do","sequence":"first","affiliation":[{"name":"Department of Dental Hygiene, Hanseo University, 46 Hanseo 1-ro, Haemi-Myun Seosan-si, Chungcheognam-do 31962, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"39017","DOI":"10.1038\/srep39017","article-title":"Association between sleep duration and cardiac structure in youths at risk for metabolic syndrome","volume":"6","author":"Feng","year":"2016","journal-title":"Sci.
