This prospective cohort study aimed to investigate the association between RA and toluene exposure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study cohort consisted of Korea Occupational Safety and Health Agency data from male workers exposed to toluene who had undergone a toluene\u2010associated special medical examination at least once between January 1, 2000 and December 31, 2004 (<jats:italic>n<\/jats:italic>\u2009=\u2009148,870). The morbidity from RA based on hospital admission records was estimated from 2000 to 2005 using National Health Insurance Claim Data. The standardized admission ratio (SAR) for RA was calculated with reference to the general population. Levels of urinary hippuric acid (HA), a metabolite of toluene, were measured and used for exposure assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Toluene\u2010exposed workers were at an elevated risk of seropositive rheumatoid arthritis (ICD\u201010 code M05) with an SAR of 2.38 (95% confidence interval [CI]: 1.14\u20134.37) and other rheumatoid arthritis (M06) with an SAR of 1.22 (95% CI: 0.91\u20131.59). When data were stratified according to the duration of toluene exposure and by tertiles of urinary HA level, no significant difference was apparent.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>SARs of the toluene\u2010exposed workers are higher than that of the general reference population, indicating that exposure to toluene may contribute to an increased risk of RA. Further studies of toluene\u2010exposed workers with longer follow\u2010up are needed.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajim.23226","type":"journal-article","created":{"date-parts":[[2021,1,29]],"date-time":"2021-01-29T12:54:36Z","timestamp":1611924876000},"page":"245-250","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Rheumatoid arthritis in low\u2010level toluene\u2010exposed workers based on nationwide medical surveillance data in Korea"],"prefix":"10.1002","volume":"64","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1508-0608","authenticated-orcid":false,"given":"Young\u2010Sun","family":"Min","sequence":"first","affiliation":[{"name":"Department of Occupational and Environmental Medicine Soonchunhyang University Cheonan Hospital  Cheonan\u2010si South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sungho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Occupational and Environmental Medicine Dongguk University Gyeongju Hospital  Gyeongju\u2010si South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mingi","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Occupational and Environmental Medicine Dankook University Cheonan Hospital  Cheonan\u2010si South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yeon\u2010Soon","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine and Genomic Cohort Institute Yonsei University Wonju College of Medicine  Wonju South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,1,29]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.berh.2017.08.003"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2019.11.007"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/annrheumdis-2015-208278"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0057304"},{"key":"e_1_2_10_6_1","first-page":"2136","volume-title":"Harrison's Principle of Internal Medicine","author":"Kasper DL","year":"2015"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1289\/EHP1013"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0051506"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/03009749409099278"},{"key":"e_1_2_10_10_1","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1136\/oemed-2018-105361","article-title":"Farming tasks and the development of rheumatoid arthritis in the agricultural health study","volume":"76","author":"Parks CG","year":"2019","journal-title":"Occup Environ Med"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1289\/EHP129"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajim.10030"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.toxlet.2010.06.022"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajim.22568"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.4093\/dmj.2014.38.5.395"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.shaw.2018.11.003"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001648-200009000-00019"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.3109\/03009749409099278"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.autrev.2012.02.001"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/1529-0131(199806)41:6<1111::AID-ART19>3.0.CO;2-J"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1080\/104732299302297"},{"key":"e_1_2_10_22_1","unstructured":"JangJK ParkH SeoHK et al.
