However, whether the occupational risks of leukemia differ among various industrial groups remains unclear. Therefore, the purpose of this study was to elucidate the occupational risks of leukemia among different worker groups by industry. Data for a total of 11,050,398 people from the National Health Insurance System\u2019s claim data from 2007 to 2015 were analyzed. By cohort inclusion of workers whose industry had not changed for three years and with total workers as a control group, the risk for a specific industry group was expressed as an age-standardized incidence ratio (SIR). Among groups by industry, \u2019Manufacture of motor vehicles and engines for motor vehicles\u2019, \u2019Sale of motor vehicle parts and accessories\u2019, and \u2019Personal care services\u2019 showed significantly higher SIRs. In division analysis, the \u2019Manufacture of other machinery and equipment\u2019 and \u2019Waste collection, treatment and disposal activities\u2019 divisions showed significantly higher SIRs than other divisions. We identified an increased risk of leukemia in workers of certain industries in Korea. Based on the results of this study, it is necessary to create a policy to protect workers at risk of leukemia. Various additional studies are needed to protect workers by revealing more precise relationships between individual hazardous substances, processes, and leukemia.<\/jats:p>","DOI":"10.3390\/ijerph20021187","type":"journal-article","created":{"date-parts":[[2023,1,10]],"date-time":"2023-01-10T01:30:47Z","timestamp":1673314247000},"page":"1187","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Risks of Leukemia in Various Industrial Groups in Korea: A Retrospective National Cohort Study"],"prefix":"10.3390","volume":"20","author":[{"given":"Won-Tae","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Occupational and Environmental Medicine, Severance Hospital, Yonsei University College of Medicine, Seoul 03722, Republic of Korea"},{"name":"Department of Public Health, Graduate School, Yonsei University, Seoul 03722, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2700-6221","authenticated-orcid":false,"given":"Woo-Ri","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Cancer Control and Policy, National Cancer Control Institute, National Cancer Center, Goyang 10408, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6408-7668","authenticated-orcid":false,"given":"Wanhyung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Occupational and Environmental Medicine, Gil Medical Center, Gachon University College of Medicine, Incheon 21565, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Ha","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Preventive Medicine, Yonsei University College of Medicine, Seoul 03722, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4337-8444","authenticated-orcid":false,"given":"Jongin","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Occupational and Environmental Medicine, Seoul St. Mary\u2019s Hospital, The Catholic University of Korea College of Medicine, Seoul 06591, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"240","DOI":"10.1093\/carcin\/bgr297","article-title":"Current understanding of the mechanism of benzene-induced leukemia in humans: Implications for risk assessment","volume":"33","author":"McHale","year":"2012","journal-title":"Carcinogenesis"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"402","DOI":"10.1093\/annweh\/wxaa008","article-title":"Occupational Co-exposures to Multiple Chemical Agents from Workplace Measurements by the US Occupational Safety and Health Administration","volume":"64","author":"Sarazin","year":"2020","journal-title":"Ann.
