Body image disturbance is an important feature of Anorexia Nervosa (AN). Some researchers have argued that body image disturbance is not just a symptom of AN, but plays a causal role in the development, persistence, and relapse of AN. Our aim was to systematically review the existing empirical evidence concerning the role of the cognitive-affective, perceptual, and behavioral components of body image disturbance in AN. 46 studies fulfilled eligibility criteria reporting about 4928 participants with AN. There is some evidence suggesting that body image disturbance is related to the course of AN. However, experimental studies were missing and operationalizations of body image constructs and AN outcome measures varied greatly across studies. Therefore, on the basis of the available empirical data, it remained unclear whether body image disturbance is indeed a causal risk factor for AN. For future studies, it is crucial to use more consistent terminology and more specific and precise definitions of body image constructs as well as experimental designs, adequately powered samples, and well-validated measures. Altogether, this would set the stage to generate the high-quality data that are necessary to clarify the role of body image disturbance in the onset, maintenance and relapse of AN.
体像障碍是神经性厌食症（AN）的一个重要特征。一些研究人员认为，体像障碍不仅仅是 AN 的一个症状，而是在 AN 的发展、持续和复发中起着因果作用。我们的目的是系统地回顾现有的关于体像障碍的认知-情感、知觉和行为成分在 AN 中的作用的实证证据。有 46 项研究符合纳入标准，报告了大约 4928 名 AN 患者。有一些证据表明体像障碍与 AN 的病程有关。然而，缺乏实验研究，并且体像结构和 AN 结果测量的操作在研究之间差异很大。因此，根据现有的实证数据，体像障碍是否确实是 AN 的一个因果风险因素仍不清楚。对于未来的研究，使用更一致的术语和更具体、更精确的体像结构定义以及实验设计、足够大的样本量和经过良好验证的测量方法至关重要。总的来说，这将为阐明体像障碍在 AN 的发病、维持和复发中的作用提供高质量的数据。
