Orthorexia nervosa is characterized by an obsession with eating "pure" or "healthy" foods. Despite emergent interest, few studies have been published about orthorexia to date. This study examined the phenomenology, correlates, and associated impairment of orthorexia in 404 undergraduate students. A battery of self-report questionnaires assessed orthorexia symptoms, related functional impairment, disordered eating, perfectionism, obsessive-compulsive symptoms, appearance anxiety, fear of negative evaluation, anxiety, and depressive symptoms. In total, 35.4% of participants endorsed elevated orthorexia symptoms, with primary concerns related to guilt associated with dietary transgressions and experiencing control when eating in a desired manner. Orthorexia symptoms demonstrated small to medium correlations with associated impairment variables, perfectionism, disordered eating, appearance anxiety, and obsessive-compulsive symptoms. Mean differences were observed across all variables (except depressive symptoms) between individuals elevated and not elevated on orthorexia symptoms. Collectively, this study suggests a relatively high frequency of orthorexia symptoms using current methods (which have significant limitations) and demonstrate fairly modest associations with psychological symptomology.
正食癖的特征是痴迷于食用“纯净”或“健康”的食物。尽管目前对此兴趣渐浓，但迄今为止关于正食癖的研究发表较少。本研究调查了404名本科生中正食癖的现象学、相关因素及相关损害。通过一系列自我报告问卷评估了正食癖症状、相关功能损害、饮食失调、完美主义、强迫症状、外貌焦虑、害怕负面评价、焦虑和抑郁症状。总体而言，35.4%的参与者认可正食癖症状有所加重，主要担忧与饮食违规相关的内疚感以及以期望的方式进食时的控制感。正食癖症状与相关损害变量、完美主义、饮食失调、外貌焦虑和强迫症状呈小到中等程度的相关性。在正食癖症状加重和未加重的个体之间，所有变量（除抑郁症状外）均观察到均值差异。总体而言，本研究表明使用当前方法（存在显著局限性）时正食癖症状的发生率相对较高，并显示出与心理症状的关联相当适度。
