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.
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。
