We used customized health information data from the National Health Insurance Corporation (NHIC). This retrospective cohort study included data from women who were not previously diagnosed with diabetes or any kind of malignancy in the National Health Screening Examination through the NHIC during 2002\u20132003, and only women who had their first delivery between 2004 and 2005 was included. Follow-up cancer diagnosis was carried out up until 2015. Among the 102,900 primiparous women, 4970 (4.83%) were diagnosed with GDM. During 10 year total follow-up period, 6569 (6.38%) cases of primary cancer were identified. The incidence of cancer was higher in women with GDM and the most common type of cancer was thyroid cancer, followed by breast cancer. On the basis of survival analysis, we adopted the Cox proportional hazards model and found that GDM was positively associated with cancer, particularly in thyroid cancer (HR: 1.27, 95% CI: 1.054\u20131.532, p = 0.012). However, the incidence of other malignancies (including ovarian and breast cancers) were not significantly associated with GDM, though they did show positive trends. Our findings suggest that GDM is associated with the incidence of cancer, particular thyroid cancer.<\/jats:p>","DOI":"10.3390\/ijerph15122646","type":"journal-article","created":{"date-parts":[[2018,11,27]],"date-time":"2018-11-27T03:31:33Z","timestamp":1543289493000},"page":"2646","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Evaluation of the Association between Gestational Diabetes Mellitus at First Pregnancy and Cancer within 10 Years Postpartum Using National Health Insurance Data in South Korea"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5817-1203","authenticated-orcid":false,"given":"Kyu-Tae","family":"Han","sequence":"first","affiliation":[{"name":"Research and Analysis Team, National Health Insurance Service Ilsan Hospital, Goyang 10444, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geum Joon","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Korea University College of Medicine, Seoul 08308, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3264-3620","authenticated-orcid":false,"given":"Eui Hyeok","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, National Health Insurance Service Ilsan Hospital, Goyang 10444, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S141","DOI":"10.2337\/dc07-s206","article-title":"Increasing prevalence of gestational diabetes mellitus: A public health perspective","volume":"30","author":"Ferrara","year":"2007","journal-title":"Diabetes Care"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"S251","DOI":"10.2337\/dc07-s225","article-title":"Summary and recommendations of the fifth international workshop-conference on gestational diabetes mellitus","volume":"30","author":"Metzger","year":"2007","journal-title":"Diabetes Care"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"414","DOI":"10.7326\/M13-2905","article-title":"Screening for gestational diabetes mellitus: US Preventive Services Task Force recommendation statement","volume":"160","author":"Moyer","year":"2014","journal-title":"Ann.
