Abstract

Purpose of review: This review summarizes recent research on the epidemiology of avoidant/restrictive food intake disorder (ARFID), including prevalence, diagnostic criteria, drivers of food avoidance, comorbidities, and illness course. It focuses on studies published in 2024 and the first half of 2025, with selected key studies from 2021 to 2023.

Recent findings: ARFID is as prevalent as other eating disorders, with estimates of 11.41% in clinical and 2.84% in nonclinical populations. It affects individuals across all age groups, confirming it as an age-independent condition. Most individuals with ARFID present with sensory sensitivity and/or low appetite, and restricted intake often results in weight loss and psychosocial impairment. Comorbidities are common and span medical, psychiatric and neurodevelopmental conditions. Several studies highlight issues with the current diagnostic criteria - particularly the exclusion of ARFID alongside other eating disorders - prompting discussions about potential revisions. Research on illness course is scarce and robust longitudinal (cohort) studies are lacking.

Summary: ARFID is marked by considerable heterogeneity affecting prevalence estimates and distribution of clinical presentation characteristics. To ensure accurate diagnosis and optimal outcomes, further research is needed - particularly to clarify diagnostic boundaries, overlap with other eating disorders, and long-term course and its predictors.

回避/限制性食物摄入障碍（ARFID）流行病学的最新见解。

综述目的：本文综述了近年来回避/限制性食物摄入障碍（ARFID）的流行病学研究，包括患病率、诊断标准、食物回避的驱动因素、合并症和病程。它重点关注2024年和2025年上半年发表的研究，并选择2021年至2023年的重点研究。最近的研究发现：ARFID与其他饮食失调一样普遍，在临床人群中估计为11.41%，在非临床人群中为2.84%。它影响所有年龄组的人，证实它是一种与年龄无关的疾病。大多数ARFID患者表现为感觉敏感和/或食欲不振，限制摄入往往导致体重减轻和社会心理障碍。合并症是常见的，跨越医学，精神和神经发育条件。一些研究强调了当前诊断标准的问题——特别是ARFID与其他饮食失调症的排除——引发了关于潜在修订的讨论。关于病程的研究很少，且缺乏可靠的纵向（队列）研究。摘要：ARFID具有显著的异质性，影响患病率估计和临床表现特征的分布。为了确保准确的诊断和最佳的结果，需要进一步的研究-特别是澄清诊断界限，与其他饮食失调的重叠，长期病程及其预测因素。
