Although anecdotal reports suggest a relation between orthorexic eating behavior and symptoms of somatoform disorders, this issue has not yet been investigated. The aim of this study was to compare orthorexic eating behavior and other characteristics of disordered eating behavior in patients with somatoform disorders to a sample of healthy controls.
31 patients with somatoform disorders and 30 matched controls completed eight questionnaires, i.a., the Düsseldorf Orthorexia Scale, three scales of the Eating Disorder Inventory-2, Eating Attitudes Test-26, Multidimensional Inventory of Hypochondriacal Traits, Attitudes Towards Body and Health Questionnaire, and Screening for Somatoform Disorders.
The patients displayed higher levels of orthorexic eating behavior, drive for thinness, body dissatisfaction, bulimia, and dieting than the control group. In both groups, orthorexic eating behavior was associated with higher levels of somatization in eating and health habits. The control group showed an association of orthorexic eating behavior with catastrophizing cognitions and the perceptual component of health anxiety.
The results support the hypothesis of a connection between orthorexic eating behavior and somatoform disorders. However, patients with somatoform disorders do not seem to be at particular risk for orthorexia. Future studies should investigate causes for the relationship between orthorexic eating behavior and characteristics of somatoform disorders in samples of healthy individuals.

尽管一些传闻报道表明，饮食行为与躯体形式障碍的症状之间存在关联，但这一问题尚未得到调查。本研究的目的是比较躯体形式障碍患者与健康对照组之间的饮食行为和其他饮食障碍特征。
31 名躯体形式障碍患者和 30 名匹配的对照组完成了八项问卷，包括杜塞尔多夫饮食强迫症量表、饮食障碍问卷-2 的三个量表、饮食态度测试-26、多维疑病症特征量表、身体和健康态度问卷以及躯体形式障碍筛查。
与对照组相比，患者表现出更高水平的饮食强迫症、追求消瘦、身体不满、暴食和节食。在两组中，饮食强迫症与进食和健康习惯中的躯体化程度更高有关。对照组中，饮食强迫症与灾难化认知和健康焦虑的知觉成分有关。
研究结果支持饮食强迫症与躯体形式障碍之间存在关联的假设。然而，躯体形式障碍患者似乎没有特别容易出现饮食强迫症。未来的研究应在健康人群样本中调查饮食强迫症与躯体形式障碍特征之间关系的原因。
V 级，具有匹配对照组的描述性研究。
