非典型神经性厌食症（AN）在社区和临床环境中越来越多地被发现。初步研究表明，与AN相比，非典型AN患者的心理症状相似或更严重。本研究检查了AN患者（n= 98），非典型AN患者（n= 18）和健康对照组（HC，n= 75）之间的饮食行为是否不同。结果AN和非典型AN与HC相比严重限制了热量摄入（431 ± 396 kcal和340 ± 338 kcal vs. 879 ± 350 kcal，F2，188= 35.4，p <0.001）。AN和非典型AN的个体在总热量的平均摄入量或脂肪热量的百分比方面没有差异（15.2 ± 25.2%vs. 11.5 ± 16.9%hDiscussionThis研究表明，非典型AN的个体至少与AN的个体一样限制他们的食物摄入，并且饮食脂肪的限制特别显著。在更大的样本中检查饮食行为将有助于复制这些发现。目前的研究强调，需要了解适应不良的饮食行为，在非典型AN，以制定适当的治疗recommends.Public SignificanceAtypical神经性厌食症正在成为一种流行的饮食失调，在社区和临床人群。非典型神经性厌食症患者限制卡路里和脂肪摄入的模式与神经性厌食症患者相似，这一发现强调了研究确定适当的治疗策略以使饮食模式正常化的必要性。
ObjectiveAtypical 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).MethodAdults 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.ResultsBoth 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< .001). 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%).DiscussionThis 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 SignificanceAtypical 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.
