Abstract

Objective: Outcomes for low-weight restrictive eating disorders, including anorexia nervosa, restricting type (AN-R) and avoidant/restrictive food intake disorder (ARFID), are sub-optimal. Reducing dietary restriction is a key treatment target. Understanding heterogeneity in patterns of change in dietary restriction may aid in improving outcomes. We examined latent trajectories of change in dietary restriction during treatment and follow-up in AN-R and ARFID.

Methods: Adolescents and adults with R-EDs (N = 276, 18% ARFID, 90% female, Mage = 18) receiving intensive ED treatment completed assessments at five timepoints. Latent growth mixture modeling examined trajectories of change in dietary restriction, measured using the Eating Pathology Symptoms Inventory Restricting subscale. Classes were compared on clinical features at admission to determine characteristics prospectively associated with trajectory.

Results: A 3-class solution emerged: Class 1 comprising individuals with "good response" (n = 138; 33% of those with ARFID in the sample); Class 2 with "good response, rebounding" (n = 81; 41% of ARFID); and Class 3 with "gradual response, low symptoms" (n = 57; 26% of ARFID). Class 3 had lower anxiety and R-ED symptoms than Classes 1 and 2. Class 2 presented with older age than Class 1.

Discussion: No ARFID-specific classes emerged, underscoring similarities in response to intensive treatment between AN-R and ARFID.

回避/限制性食物摄入障碍和神经性厌食症治疗期间饮食限制变化的潜在轨迹。
目的:包括神经性厌食症、限制性型(AN-R)和回避/限制性食物摄入障碍(ARFID)在内的低体重限制性饮食障碍的结局均不理想。减少饮食限制是一个关键的治疗目标。了解饮食限制变化模式的异质性可能有助于改善结果。我们检查了在AN-R和ARFID治疗和随访期间饮食限制变化的潜在轨迹。方法:接受强化ED治疗的青少年和成人r -ED患者(N = 276, ARFID 18%,女性90%,Mage = 18)在5个时间点完成评估。潜在生长混合物模型检查了饮食限制的变化轨迹,使用饮食病理症状清单限制亚量表进行测量。各班级在入院时的临床特征进行比较,以确定与预后相关的特征。结果:出现了一个3级解决方案:第1级包括“良好反应”的个体(n = 138;样本中ARFID患者的33%);第2类“响应好,有反弹”(n = 81;ARFID的41%);3级:“反应缓慢,症状较轻”(n = 57;26%的ARFID)。3级患者的焦虑和R-ED症状低于1级和2级患者。2类比1类年龄大。讨论:没有出现ARFID特异性分类,强调了AN-R和ARFID在强化治疗反应上的相似性。

期刊介绍: Articles featured in the journal describe state-of-the-art scientific research on theory, methodology, etiology, clinical practice, and policy related to eating disorders, as well as contributions that facilitate scholarly critique and discussion of science and practice in the field. Theoretical and empirical work on obesity or healthy eating falls within the journal’s scope inasmuch as it facilitates the advancement of efforts to describe and understand, prevent, or treat eating disorders. IJED welcomes submissions from all regions of the world and representing all levels of inquiry (including basic science, clinical trials, implementation research, and dissemination studies), and across a full range of scientific methods, disciplines, and approaches.
