Orthorexia nervosa (ON) has emerged as a new pattern of disordered eating behaviors characterized by preoccupations related to diet quality and health concerns, rather than driven by weight and shape concerns. A growing body of cross-sectional empirical data has documented associations between orthorexia nervosa symptoms and other indicators of disordered eating. However, little attention has been paid to the potential relationship between ON symptoms and indicators of healthy eating or positive eating behaviors. The aim of the present study was therefore to evaluate the relationships between ON symptomatology and the different facets of intuitive eating and eating competence. A sample of n = 605, 19% male, college students from the USA completed an online survey assessing orthorexia nervosa behaviors, the four facets of intuitive eating, and eating competence. Overall, orthorexia nervosa behaviors were found to be associated with lower levels of positive eating attitudes and behaviors. However, among men, curvilinear convex relationships emerged for two facets of intuitive eating, Body-Food Choice Congruence and Reliance on Hunger and Satiety Cues, such that the highest levels of intuitive eating were reported by those with mid-range levels of orthorexia nervosa behaviors. Taken together, these findings suggest that broadly, patterns of eating characterized by restriction, albeit for health reasons, are associated with less positive eating behaviors particularly among women. Further work focused on evaluating how drive for a healthy diet can be associated with flexible and positive eating patterns is warranted.Level of evidence Level V descriptive cross-sectional study.
神经强迫症（ON）已成为一种新的饮食行为失调模式，其特征是专注于饮食质量和健康问题，而不是体重和体型问题。越来越多的横断面实证数据记录了神经强迫症症状与其他饮食失调指标之间的关联。然而，很少有人关注 ON 症状与健康饮食或积极饮食行为之间的潜在关系。因此，本研究旨在评估 ON 症状与直觉饮食和饮食能力不同方面之间的关系。本研究的样本为 n=605 名美国大学生，其中 19%为男性，完成了一项在线调查，评估了神经强迫症行为、直觉饮食的四个方面和饮食能力。总体而言，神经强迫症行为与积极的饮食态度和行为呈负相关。然而，对于男性而言，直觉饮食的两个方面，即身体-食物选择一致性和对饥饿和饱腹感线索的依赖，呈现出曲线凸性关系，即神经强迫症行为中等水平的人报告的直觉饮食水平最高。综上所述，这些发现表明，广泛而言，以限制为特征的饮食模式，尽管是出于健康原因，与较少的积极饮食行为有关，尤其是在女性中。进一步的工作集中在评估健康饮食的驱动力如何与灵活和积极的饮食模式相关。证据水平为五级描述性横断面研究。
