Abstract：
OBJECTIVE: Eating disorders (EDs) increasingly emerge as a health risk in men, but there is concern that men\'s symptoms go unnoticed due to stereotypical perceptions and gender-related differences in symptom presentation. Novel assessments focused particularly on attitudes and behaviours towards increasing muscle size and definition. Using network analysis, this study aimed to corroborate and extend previous findings on disordered eating presentation in men by examining the role of muscularity concerns among an extended range of disordered eating symptoms.
METHODS: N = 294 adult men (18 years or older) completed muscularity-related and disordered eating assessments, among which we included assessments for orthorexic eating and Avoidant/Restrictive Food Intake Disorder for the first time. We selected symptoms empirically, estimated a regularised network, identified symptom communities, evaluated network loadings and bridge centrality estimates, and compared network structures between different groups of participants.
RESULTS: We identified five symptom communities related to muscularity-related concerns, features of core ED psychopathology, and selective eating. Symptoms regarding ruminating about healthy eating, guilt for unhealthy eating, weight overvaluation, concerns about muscularity, and selective eating emerged as highly central.
CONCLUSIONS: The results largely corroborate previous observations but suggest that muscle-building behaviours are part of a broader cluster of male body shaping and rule-based dieting behaviours.

摘要：
目标：饮食失调（ED）越来越成为男性的健康风险，但有人担心，男性的症状被忽视，由于刻板印象和性别相关的差异，在症状表现。新的评估特别侧重于对增加肌肉大小和定义的态度和行为。使用网络分析，这项研究旨在通过检查肌肉问题在广泛的饮食失调症状中的作用，证实和扩展先前关于男性饮食失调表现的发现。
方法：N=294名成年男性（18岁或以上）完成了与肌肉相关的饮食紊乱评估，其中我们首次纳入了对正交性进食和回避/限制性食物摄入障碍的评估。我们根据经验选择症状，估计一个正则化的网络，确定的症状社区，评估的网络荷载和桥梁中心性估计，并比较了不同参与者群体之间的网络结构。
结果：我们确定了五个与肌肉相关的症状群，核心ED精神病理学的特征，有选择性的吃。关于反思健康饮食的症状，对不健康的饮食感到内疚，重量高估，对肌肉组织的担忧，选择性饮食变得非常重要。
结论：结果在很大程度上证实了以前的观察结果，但表明肌肉锻炼行为是更广泛的男性身体塑造和基于规则的节食行为的一部分。
