We aimed to determine whether CD is associated with the diagnosis of AN.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS:<\/jats:title>\n                  <jats:p>Register-based cohort and case-control study including women with CD (n = 17\u2009959) and sex- and age-matched population-based controls (n = 89\u2009379). CD (villous atrophy) was identified through the histopathology records of Sweden\u2019s 28 pathology departments. Inpatient and hospital-based outpatient records were used to identify AN. Hazard ratios for incident AN diagnosis were estimated by using stratified Cox regression with CD diagnosis as a time-dependent exposure variable. In the secondary analyses, we used conditional logistic regression to estimate odds ratios for being diagnosed with AN before CD.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>Median age of CD diagnosis was 28 years. During 1\u2009174\u2009401 person-years of follow-up, 54 patients with CD were diagnosed with AN (27\/100\u2009000 person-years) compared with 180 matched controls (18\/100\u2009000 person-years). The hazard ratio for later AN was 1.46 (95% confidence interval [CI], 1.08\u20131.98) and 1.31 beyond the first year after CD diagnosis (95% CI, 0.95\u20131.81). A previous AN diagnosis was also associated with CD (odds ratio, 2.18; 95% CI, 1.45\u20133.29). Estimates remained largely unchanged when adjusted for socioeconomic characteristics and type 1 diabetes.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>The bidirectional association between AN diagnosis and CD warrants attention in the initial assessment and follow-up of these conditions because underdiagnosis and misdiagnosis of these disorders likely cause protracted and unnecessary morbidity.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1542\/peds.2016-4367","type":"journal-article","created":{"date-parts":[[2017,4,3]],"date-time":"2017-04-03T09:10:13Z","timestamp":1491210613000},"source":"Crossref","is-referenced-by-count":87,"title":["Celiac Disease and Anorexia Nervosa: A Nationwide Study"],"prefix":"10.1542","volume":"139","author":[{"given":"Karl","family":"M\u00e5rild","sequence":"first","affiliation":[{"name":"Division of Epidemiology, Norwegian Institute of Public Health, Oslo, Norway;"},{"name":"Barbara Davis Center, University of Colorado, Aurora, Colorado;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ketil","family":"St\u00f8rdal","sequence":"additional","affiliation":[{"name":"Division of Epidemiology, Norwegian Institute of Public Health, Oslo, Norway;"},{"name":"Department of Pediatrics, \u00d8stfold Hospital Trust, Gr\u00e5lum, Norway;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cynthia M.","family":"Bulik","sequence":"additional","affiliation":[{"name":"Department of Medical Epidemiology and Biostatistics and"},{"name":"Departments of Psychiatry and"},{"name":"Nutrition, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marian","family":"Rewers","sequence":"additional","affiliation":[{"name":"Barbara Davis Center, University of Colorado, Aurora, Colorado;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anders","family":"Ekbom","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit, Department of Medicine Solna, Karolinska Institutet, Stockholm, Sweden;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edwin","family":"Liu","sequence":"additional","affiliation":[{"name":"Barbara Davis Center, University of Colorado, Aurora, Colorado;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonas F.","family":"Ludvigsson","sequence":"additional","affiliation":[{"name":"Department of Medical Epidemiology and Biostatistics and"},{"name":"Department of Pediatrics, \u00d6rebro University Hospital, \u00d6rebro University, \u00d6rebro, Sweden;"},{"name":"Division of Epidemiology and Public Health, School of Medicine, University of Nottingham, Nottingham, United Kingdom;
