Orthorexia Nervosa (ON) is described as an obsessive behaviour motivated by great concern for following a healthy diet. Although it was first described in 1997, ON remains inconspicuous and poorly characterized in the literature. The aims of this study were to evaluate the prevalence of ON in a sample of ambulatory individuals and to investigate their common characteristics, attempting to better characterize this entity.
A non-random sample of 193 adult gym members answered a questionnaire based on a Portuguese version of ORTO-15, supplemented with additional questions. Possible associations between the different variables and pathological scores on ORTO-15 were analysed using logistic regression models.
ON behaviour was documented in 51.8% of the sample, mean age 30.96 years (± 1.03 years), and this condition tended to be correlated with younger ages. Physical appearance and frequent exercising were also associated with ON, while no correlation between orthorexic tendencies and both gender and educational field was found. Furthermore, consumption of special food, dissatisfaction with physical appearance and frequent exercising could predict the presence of ON in the sample.
Despite the use of a convenience sample, results place us in a different perspective, considering the idea that orthorexic individuals are exclusively concerned about pursuing a pure diet. The presence of ON was associated with other non-dietary behaviours allied to a healthy lifestyle and aesthetic concerns.

orthorexia nervosa（ON，即健康饮食强迫症）被描述为一种由对遵循健康饮食的高度关注所驱动的强迫行为。尽管它在1997年首次被描述，但在文献中ON仍然不明显且特征描述不足。本研究的目的是评估门诊个体样本中ON的患病率，并调查他们的共同特征，试图更好地描述这一实体。
193名成年健身会员的非随机样本回答了一份基于葡萄牙语版ORTO - 15的问卷，并补充了其他问题。使用逻辑回归模型分析不同变量与ORTO - 15病理评分之间可能的关联。
样本中有51.8%记录了ON行为，平均年龄30.96岁（±1.03岁），这种情况往往与较年轻的年龄相关。外貌和频繁锻炼也与ON有关，而在健康饮食强迫症倾向与性别和教育领域之间未发现相关性。此外，食用特殊食物、对外貌不满意和频繁锻炼可以预测样本中ON的存在。
尽管使用的是便利样本，但考虑到健康饮食强迫症患者只关注追求纯净饮食这一观点，研究结果让我们从不同角度看待这一问题。ON的存在与其他与健康生活方式和审美关注相关的非饮食行为有关。
