Orthorexia Nervosa is characterised by a pathological fixation on food purity and nutrition, coupled with a severely restricted diet and avoidance of food believed to be unhealthy. Little is known about the risk factors associated with the condition or if the condition should be treated in a similar way to other eating disorders or whether distinct interventions are required. This study aimed to identify (1) putative variables of the need for treatment in those with orthorexia symptomology and (2) assess whether comorbid psychological symptomologies were associated with orthorexia nervosa. An online cross-sectional self-report survey was developed and the data of 130 participants analysed using regression analyses. As predicted, individuals with higher levels of orthorexic symptomology, eating disorder symptomology and those who identified their healthy eating as problematic were significantly more likely to have a perceived need for treatment, however those who self-identified as having a current or past eating disorder were not. Orthorexic symptomatology was significantly correlated with eating disorder symptomatology, obsessive-compulsive symptoms, anxiety, and depression, however in the regression analysis, eating disorder symptomatology was the only significant variable. These findings highlight the need to consider orthorexic symptoms in people with eating disorders and that this inter-relationship and the ego-syntonicity of symptoms may reduce help-seeking.
饮食强迫症的特点是对食物纯净和营养的病态关注，加上严重限制饮食和避免被认为不健康的食物。人们对与这种情况相关的风险因素知之甚少，或者这种情况是否应该以与其他饮食失调相同的方式治疗，或者是否需要不同的干预措施。本研究旨在确定（1）有饮食强迫症症状的人需要治疗的可能变量，（2）评估共病心理症状是否与饮食强迫症有关。开发了一个在线横断面自我报告调查，使用回归分析对 130 名参与者的数据进行了分析。正如预测的那样，饮食强迫症症状、饮食失调症状水平较高的个体，以及那些认为自己的健康饮食有问题的个体，更有可能有治疗的需求，但那些自我认同为当前或过去有饮食障碍的个体则不然。饮食强迫症症状与饮食失调症状、强迫症症状、焦虑和抑郁显著相关，但在回归分析中，饮食失调症状是唯一显著的变量。这些发现强调了在饮食失调患者中需要考虑饮食强迫症症状，并且这种相互关系和症状的自我和谐可能会减少寻求帮助。
