The study aimed to model the total numbers of people with undiagnosed type 2 diabetes and prediabetes in Denmark based on existing population-based surveys. Methods: Two population-based Danish studies with information on HbA\n                    <jats:sub>1c<\/jats:sub>\n                    , date of examination, gender, age and known type 2 diabetes were identified: the Danish General Suburban Population Study, n = 21,205, and the Danish Health Examination Survey, n = 18,065. The prevalence of known, undiagnosed and pre-diabetes were estimated in the Danish General Suburban Population Study, and population-level age-specific prevalence of known type 2 diabetes was estimated from national registers. The Danish Health Examination Survey was included for sensitivity analysis. Combining estimates of the survey participation rate among known type 2 diabetes patients with known overall participation rates from the studies allowed for the correction of survey prevalence to plausible population-level estimates of age- and gender-specific prevalence. Results: The prevalence of known, undiagnosed and pre-diabetes was highest among men, increasing with age with a peak at age 70. Applying the survey-based prevalence to the entire Danish population, the estimated number (May 2011) with undiagnosed type 2 diabetes was 60,681, corresponding to 24% of all type 2 diabetes cases, and 292,715 had prediabetes, about 50% more than the total type 2 diabetes population. Conclusions: Estimates of undiagnosed type 2 diabetes and prediabetes are dramatically lower than reported in previous studies (60,681 vs 200,000 and 292,715 vs 750,000); however, whether this reflects a true decrease in incidence or the change to HbA\n                    <jats:sub>1c<\/jats:sub>\n                    -based diagnostic criteria is not clear.\n                  <\/jats:p>","DOI":"10.1177\/1403494818799606","type":"journal-article","created":{"date-parts":[[2018,9,17]],"date-time":"2018-09-17T11:57:19Z","timestamp":1537185439000},"page":"106-112","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":43,"title":["Estimates of prediabetes and undiagnosed type 2 diabetes in Denmark: The end of an epidemic or a diagnostic artefact?"],"prefix":"10.1177","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8356-5565","authenticated-orcid":false,"given":"Marit Eika","family":"J\u00f8rgensen","sequence":"first","affiliation":[{"name":"Steno Diabetes Center Copenhagen, Gentofte, Denmark"},{"name":"National Institute of Public Health, University of Southern Denmark, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christina","family":"Ellervik","sequence":"additional","affiliation":[{"name":"Division of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark"},{"name":"Department of Production, Research, and Innovation; Region Zealand, Sor\u00f8, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ola","family":"Ekholm","sequence":"additional","affiliation":[{"name":"National Institute of Public Health, University of Southern Denmark, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nanna Borup","family":"Johansen","sequence":"additional","affiliation":[{"name":"Center for Clinical Research and Prevention, Bispebjerg and Frederiksberg Hospital, Copenhagen, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bendix","family":"Carstensen","sequence":"additional","affiliation":[{"name":"Steno Diabetes Center Copenhagen, Gentofte, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,9,17]]},"reference":[{"key":"bibr1-1403494818799606","doi-asserted-by":"publisher","DOI":"10.1007\/s00125-008-1156-z"},{"key":"bibr2-1403494818799606","unstructured":"International Diabetes Federation.
