Orthorexia, from the Greek words orthos (straight, proper) and orexis (appetite), is a newly conceptualized disorder characterized by distorted eating habits and cognitions concerning supposedly healthy nutrition. In this article we present preliminary results of a wider research aimed to investigate the diffusion of Orthorexia in the general population and to highlight its characteristics and particularly the relationship with Eating Disorder and Obsessive-Compulsive Disorder.
One-hundred and seventy seven adult subjects from the general population, were administered the ORTO-15 test, a selfadministered questionnaire specifically designed to assess orthorexic symptomatology; note that statistical analyses were repeated twice, referring to different diagnostic thresholds (40/35).
Orthorexia had a 57.6% prevalence in our sample, using the 40-point threshold, with a female/male ratio 2:1; the figure was sensibly lower with the 35-point threshold (21%).
The results of this study highlight the diffusion of Orthorexia which may constitute an important risk factor for mental and physical health, but also the opportunity of more specific diagnostic instruments, so to facilitate a thorough understanding of this disorder.
源于希腊语 orthos（正确的、恰当的）和 orexis（食欲）的“饮食强迫症”是一种新提出的紊乱症，其特点是饮食和对健康营养的认知出现扭曲。在本文中，我们呈现了一项更广泛研究的初步结果，旨在调查“饮食强迫症”在普通人群中的流行情况，并强调其特征，特别是与饮食失调和强迫症的关系。
我们对 177 名普通人群中的成年受试者进行了 ORTO-15 测试，这是一种专门用于评估饮食强迫症症状的自我管理问卷；需要注意的是，统计分析重复了两次，参考了不同的诊断阈值（40/35）。
在我们的样本中，使用 40 分的阈值，“饮食强迫症”的患病率为 57.6%，女性/男性比例为 2:1；使用 35 分的阈值，这一数字明显较低（21%）。
这项研究的结果强调了“饮食强迫症”的流行，这可能是心理健康和身体健康的一个重要风险因素，但也需要更具体的诊断工具，以便更全面地了解这种紊乱症。
