This systematic review assesses AAN literature from 2007 to 2020, to investigate: (a) the demographic characteristics of AAN studies, (b) the prevalence of AAN compared with AN, (c) the range of operational definitions of AAN and the implications of these definitions, and (d) the proportion of patients with AAN and AN represented in consecutive admission and referral samples.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>PsychINFO, CINAHL, PubMed, <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"http:\/\/greylit.org\">Greylit.org<\/jats:ext-link>, and ProQuest databases were searched according to methods for Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses systematic reviews, yielding 3,184 potential articles.

In epidemiological designs, AAN was typically as common or more common than AN, and AAN rates varied significantly based on the population studied and operational definitions. In consecutive clinical samples, AAN was frequently less represented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Although AAN appears to occur more frequently than AN in communities, fewer patients with AAN are being referred and admitted to eating disorder specific care, particularly in the United States. Given the significant medical and psychosocial consequences of AAN, and the importance of early intervention, this represents a crucial treatment gap. Additionally, results suggest the need for fine\u2010tuning diagnostic definitions, greater diversity in AAN studies, and increased screening and referral for this vulnerable population.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23519","type":"journal-article","created":{"date-parts":[[2021,4,17]],"date-time":"2021-04-17T07:29:34Z","timestamp":1618644574000},"page":"1328-1357","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":139,"title":["Restrictive eating disorders in higher weight persons: A systematic review of atypical anorexia nervosa prevalence and consecutive admission literature"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0933-1098","authenticated-orcid":false,"given":"Erin N.","family":"Harrop","sequence":"first","affiliation":[{"name":"Graduate School of Social Work University of Denver  Denver Colorado USA"},{"name":"School of Social Work University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7675-8879","authenticated-orcid":false,"given":"Janell L.","family":"Mensinger","sequence":"additional","affiliation":[{"name":"College of Nursing Villanova University  Villanova Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Moore","sequence":"additional","affiliation":[{"name":"School of Social Work University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4613-6563","authenticated-orcid":false,"given":"Taryn","family":"Lindhorst","sequence":"additional","affiliation":[{"name":"School of Social Work University of Washington  Seattle Washington USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,4,17]]},"reference":[{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0034004"},{"key":"e_1_2_13_4_1","volume-title":"Diagnostic and statistical manual of mental disorders: DSM\u2010IV\u2010TR","author":"American Psychiatric Association","year":"2000"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/1359104519827629"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.14310\/horm.2002.1717"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.3109\/10398562.2011.603328"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20968"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.enfcle.2018.03.002"},{"key":"e_1_2_13_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40337-015-0072-0"},{"key":"e_1_2_13_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22074"},{"key":"e_1_2_13_13_1","doi-asserted-by":"publisher","DOI":"10.1080\/10640266.2014.1000106"},{"key":"e_1_2_13_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.2531"},{"key":"e_1_2_13_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40337-015-0060-4"},{"key":"e_1_2_13_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/chi.0b013e31815cd9cf"},{"key":"e_1_2_13_17_1","doi-asserted-by":"publisher","DOI":"10.1186\/2050-2974-1-31"},{"key":"e_1_2_13_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22780"},{"key":"e_1_2_13_19_1","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.bp.110.083881"},{"key":"e_1_2_13_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22257"},{"key":"e_1_2_13_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.2348"},{"key":"e_1_2_13_22_1","unstructured":"*Flatt Rachael E.(2020).Comparing eating disorder characteristics and treatment in self\u2010identified athletes from the National Eating Disorders Association Online Screening Tool (Order No. 28000289).
