The recent DSM-5 categorization of eating disorders introduces a new category of eating disorders, Unspecified Feeding and Eating Disorders (UFED), where symptoms do not meet criteria for any other diagnostic category, but cause clinically significant distress or impairment. The aim of the current study was to explore what disorders in UFED might look like in an adolescent population.
We examined a large cohort of adolescent female twins (N = 699) who were assessed on three occasions and who did not meet a DSM-5 eating disorder diagnosis but who reported threshold levels of either fasting and/or driven exercise (N = 33; 4.7%). This group of girls was compared to girls who reported no eating disorder over the three waves, and girls who met a diagnosis of either anorexia nervosa (AN) or atypical AN.
The UFED group was characterized as being in the overweight range while striving to lose weight, and placing a high degree of importance on weight and shape in their self-evaluation. This group was indistinguishable from the two eating disorder groups on measures of global eating disorder severity, and demonstrated significantly elevated impairment and distress compared to the no eating disorder group commensurate with the eating disorder groups.
Further research of this group is necessary to ensure that these individuals are not overlooked, and that treatment options are appropriate and available.
DSM-5 最近对进食障碍进行了分类，引入了一个新的进食障碍类别，未特定的进食和饮食障碍（UFED），其中的症状不符合任何其他诊断类别的标准，但会引起临床显著的困扰或损伤。本研究的目的是探讨 UFED 中的哪些障碍在青少年人群中可能出现。
我们检查了一个大型的青少年女性双胞胎队列（N=699），这些双胞胎在三个时间点接受评估，且未符合 DSM-5 进食障碍诊断标准，但报告了禁食和/或强制运动的阈限值（N=33；4.7%）。与在三个波次中均报告无进食障碍的女孩，以及报告符合厌食症或非典型厌食症诊断的女孩相比，这些女孩组成了 UFED 组。
UFED 组的特征是超重，同时努力减肥，并在自我评估中高度重视体重和体型。与两个进食障碍组相比，该组在整体进食障碍严重程度的衡量指标上没有区别，且与无进食障碍组相比，其障碍程度和困扰程度显著升高，与进食障碍组相当。
需要进一步研究该组人群，以确保这些个体不会被忽视，并且治疗选择是适当和可用的。
