To review the literature on the prevalence, risk groups and risk factors of the alleged eating disorder orthorexia nervosa.
We searched Medline and Pubmed using several key terms relating to orthorexia nervosa (ON) and checked the reference list of the articles that we found. Attention was given to methodological problems in these studies, such as the use of non-validated assessment instruments, small sample size and sample characteristics, which make generalization of the results impossible.
Eleven studies were found. The average prevalence rate for orthorexia was 6.9 % for the general population and 35-57.8 % for high-risk groups (healthcare professionals, artists). Dieticians and other healthcare professionals are at high risk of ON. Risk factors include obsessive-compulsive features, eating-related disturbances and higher socioeconomic status. Relevant clinical experience, published literature and research data have increased in the last few years.
The definition and diagnostic criteria of ON remain unclear. Further studies are needed to clarify appropriate diagnostic methods and the place of ON among psychopathological categories.
综述关于所谓的饮食失调症——健康食品痴迷症的流行率、风险群体和风险因素的文献。
我们使用与健康食品痴迷症（ON）相关的几个关键词在 Medline 和 Pubmed 上进行了检索，并检查了我们找到的文章的参考文献列表。我们关注了这些研究中的方法学问题，例如使用非有效评估工具、样本量小和样本特征，这使得结果无法推广。
共发现 11 项研究。一般人群中健康食品痴迷症的平均流行率为 6.9%，高危群体（医疗保健专业人员、艺术家）为 35-57.8%。营养师和其他医疗保健专业人员患 ON 的风险较高。风险因素包括强迫性特征、与饮食相关的障碍和较高的社会经济地位。近年来，相关的临床经验、已发表的文献和研究数据有所增加。
ON 的定义和诊断标准仍不明确。需要进一步的研究来澄清适当的诊断方法和 ON 在精神病理学类别中的位置。
