Clean eating (i.e., eating healthy foods largely from nature) has become a recent popular lifestyle trend. Orthorexia is the term used to describe a pathological preoccupation with healthy eating which causes significant impairment in one's life. The present study examined orthorexia symptoms in relation to sample characteristics, weight/shape concerns, eating behaviors, and mood in a general population sample in the United States. Participants included 217 adults who completed surveys on weight/shape concerns, eating behaviors, and mood via the data collection site, Prolific. Men had higher orthorexia symptoms than women. Across all participants, orthorexia was not related to weight/shape concerns but was related to higher weight-related restraint eating behaviors. Orthorexia was not related to stress or negative emotions; however, it was related to having higher well-being. Multiple regressions revealed how the main variables predicted orthorexia symptoms separately by gender. Routine restraint, emotional eating, stress, and well-being were significant predictors of orthorexia for men. Weight/shape concerns, routine restraint, stress, and negative emotion were significant predictors of orthorexia for women. As such, it appears that orthorexia symptomatology has both advantageous and disadvantageous associations and differentially affects men and women.
清洁饮食（即主要从大自然中摄取健康食物）已成为最近流行的生活方式趋势。饮食强迫症是用来描述一种对健康饮食的病态关注，这种关注会导致一个人的生活出现严重障碍。本研究在美国的一般人群样本中，考察了与样本特征、体重/体型担忧、饮食行为和情绪有关的饮食强迫症症状。参与者包括 217 名通过数据收集网站 Prolific 完成体重/体型担忧、饮食行为和情绪调查的成年人。男性的饮食强迫症症状比女性更严重。在所有参与者中，饮食强迫症与体重/体型担忧无关，但与更高的与体重相关的节制饮食行为有关。饮食强迫症与压力或负面情绪无关；然而，它与更高的幸福感有关。多元回归显示了主要变量如何分别按性别预测饮食强迫症症状。常规节制、情绪性进食、压力和幸福感是男性饮食强迫症的重要预测因素。体重/体型担忧、常规节制、压力和负面情绪是女性饮食强迫症的重要预测因素。因此，饮食强迫症症状似乎既有有利的也有不利的关联，并且对男性和女性的影响不同。
