Eating behavior in atypical anorexia nervosa

Objective Atypical anorexia nervosa (AN) has been increasingly identified in the community and in clinical settings. Initial studies indicate that psychological symptoms are similar or more severe among patients with atypical AN, as compared with AN. This study examined whether eating behavior diffe...

description Objective Atypical anorexia nervosa (AN) has been increasingly identified in the community and in clinical settings. Initial studies indicate that psychological symptoms are similar or more severe among patients with atypical AN, as compared with AN. This study examined whether eating behavior differed among patients with AN (n = 98), patients with atypical AN (n = 18), and healthy controls (HC, n = 75). Method Adults and adolescents chose what to eat from a standardized, laboratory‐based multi‐item meal. Total intake, macronutrient composition, diet variety, and energy density were compared between groups. Results Both AN and atypical AN severely restricted caloric intake as compared with HC (431 ± 396 kcal and 340 ± 338 kcal vs. 879 ± 350 kcal, F2,188 = 35.4, p

Individuals with AN and atypical AN did not differ in the mean intake of total calories or percentage of calories from fat (15.2 ± 25.2% vs. 11.5 ± 16.9%). Discussion This study demonstrates that individuals with atypical AN are at least as restrictive in their food intake as individuals with AN, and the restriction of dietary fat is particularly notable. Examination of eating behavior in a larger sample would be useful to replicate these findings. The current study highlights the need to understand maladaptive eating behavior in atypical AN in order to develop appropriate treatment recommendations. Public Significance Atypical anorexia nervosa is emerging as a prevalent eating disorder in community and clinical populations. The findings that patients with atypical anorexia nervosa limit calorie and fat intake in a pattern similar to that of patients with anorexia nervosa highlights the need for research to identify appropriate treatment strategies for normalization of eating patterns.</description><identifier>ISSN: 0276-3478</identifier><identifier>EISSN: 1098-108X</identifier><identifier>DOI: 10.1002/eat.23886</identifier><identifier>PMID: 36584139</identifier><language>eng</language><publisher>Hoboken, USA: John Wiley &amp; Sons, Inc</publisher><subject>Adolescent ; Adult ; Anorexia ; anorexia nervosa ; Anorexia Nervosa - therapy ; atypical anorexia nervosa ; Diet - psychology ; Dietary Fats ; Eating - psychology ; Eating behavior ; Energy Intake ; Feeding Behavior - psychology ; food choice ; Humans ; laboratory meal</subject><ispartof>The International journal of eating disorders, 2024-04, Vol.57 (4), p.780-784</ispartof><rights>2022 Wiley Periodicals LLC.</rights><rights>2024 Wiley Periodicals LLC.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3536-f4d358dba88998024ec53b46dd9de3ac5ed484f9c85e4714e97166af58f8673f3</citedby><cites>FETCH-LOGICAL-c3536-f4d358dba88998024ec53b46dd9de3ac5ed484f9c85e4714e97166af58f8673f3</cites><orcidid>0000-0001-8434-8212 ; 0000-0001-8626-5859</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/36584139$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Jablonski, Monica</creatorcontrib><creatorcontrib>Schebendach, Janet</creatorcontrib><creatorcontrib>Walsh, B.
