For women, abdominal obesity increased the chance of tooth loss by 64% (odds ratio [OR]: 1.64, 95% confidence interval [CI]: 1.16–2.34) in the NHANES and 196% (OR: 2.96, 95% CI: 1.47–5.97) in the SHeS. For men, abdominal obesity increased the chance of tooth loss by 41% (OR: 1.41, 95% CI: 1.06–1.87) in the NHANES and 65% (OR: 1.65, 95% CI: 1.02–2.73) in the SHeS.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>This study indicated that the prevalence of tooth loss is substantially higher in people with abdominal obesity, and this association is distinctively different between men and women. These findings suggest that those who are not obese but have abdominal obesity may be an important target population for oral health prevention strategies.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10203,"journal":{"name":"Clinical and Experimental Dental Research","volume":"10 6","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cre2.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142674063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
