To analyse the relation of illness anxiety, dysfunctional cognitions characteristic of somatic symptom disorders and orthorexic eating behaviour in a non-clinical sample.
N = 445 participants (n = 363 females) completed an online survey with the following questionnaires: the Düsseldorf Orthorexia Scale to measure orthorexic eating behaviour, the Attitudes Towards Body and Health Questionnaire to assess dysfunctional cognitions concerning the perception and interpretation of bodily sensations and the Multidimensional Inventory of Hypochondriacal Traits to measure illness anxiety.
In the total sample, orthorexic eating behaviour was associated with the aforementioned variables to a very low extent. However, individuals with high levels of orthorexic eating behaviour (n = 19) displayed significantly higher levels of health habits and of perceptions of autonomic sensations, as well as higher levels of hypochondriacal worry and absorption than individuals with low levels of orthorexic eating behaviour (n = 19).
Orthorexic eating behaviour is associated to some characteristic features of illness anxiety and dysfunctional cognitions characteristic of somatic symptom disorders. Future studies should investigate whether illness anxiety serves as a risk factor for the development of orthorexic eating behaviour.

分析非临床样本中疾病焦虑、躯体症状障碍特征性的认知障碍与健康型饮食行为之间的关系。
共 445 名参与者（n=363 名女性）完成了一项在线调查，其中包括以下问卷：杜塞尔多夫健康饮食强迫症量表用于测量健康型饮食行为，对身体和健康的态度问卷用于评估对身体感觉的感知和解释的认知障碍，多维疑病症特征清单用于测量疾病焦虑。
在总样本中，健康型饮食行为与上述变量的关联程度非常低。然而，高水平健康型饮食行为的个体（n=19）比低水平健康型饮食行为的个体（n=19）表现出更高的健康习惯水平、对自主感觉的感知水平、疑病症担忧和吸收水平。
健康型饮食行为与疾病焦虑的某些特征以及躯体症状障碍特征性的认知障碍有关。未来的研究应调查疾病焦虑是否是健康型饮食行为发展的风险因素。
III，病例对照分析研究。
