We investigated the effects of BMI on PONV, taking into account other PONV risk factors. We analyzed adults over the age of 18 years who received general anesthesia between 2015 and 2019, using propensity score matching. Before propensity score matching, odds ratios (ORs) for PONV were lower for overweight (OR, 0.91; 95% confidence interval (CI), 0.87\u20130.96; p &lt; 0.0001) or obese patients (OR, 0.77; 95% CI, 0.71\u20130.84; p &lt; 0.0001) than for normal-BMI patients. After matching, the ORs for PONV of overweight (OR, 0.89; 95% CI, 0.80\u20130.98; p = 0.016) and obese patients (OR, 0.71; 95% CI, 0.63\u20130.79; p &lt; 0.0001) were low. However, the ORs of underweight patients did not differ from those of normal-BMI patients, irrespective of matching. Therefore, the incidence of PONV may be lower among adults with a higher-than-normal BMI.<\/jats:p>","DOI":"10.3390\/jcm9061612","type":"journal-article","created":{"date-parts":[[2020,5,29]],"date-time":"2020-05-29T00:44:02Z","timestamp":1590713042000},"page":"1612","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Effect of Body Mass Index on Postoperative Nausea and Vomiting: Propensity Analysis"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3818-2239","authenticated-orcid":false,"given":"Jong Ho","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, College of Medicine, Hallym University, Chuncheon 24253, Korea"},{"name":"Institute of New Frontier Research Team, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingi","family":"Hong","sequence":"additional","affiliation":[{"name":"Institute of New Frontier Research Team, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Young Joon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, College of Medicine, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ho Seok","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, College of Medicine, Hallym University, Chuncheon 24253, Korea"},{"name":"Institute of New Frontier Research Team, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7753-8464","authenticated-orcid":false,"given":"Young Suk","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, College of Medicine, Hallym University, Chuncheon 24253, Korea"},{"name":"Institute of New Frontier Research Team, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Jun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Medicine, Chuncheon Sacred Heart Hospital, College of Medicine, Hallym University, Chuncheon 24253, Korea"},{"name":"Institute of New Frontier Research Team, Hallym University, Chuncheon 24253, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"480","DOI":"10.1034\/j.1399-6576.2000.440422.x","article-title":"Evaluation of three risk scores to predict postoperative nausea and vomiting","volume":"44","author":"Eberhart","year":"2000","journal-title":"Acta Anaesthesiol.
