Orthorexia Nervosa in China: An Exploration of Phenomenology and Clinical Correlates Among University Students.

Orthorexia nervosa, characterized by pathological preoccupation with healthy eating and food purity, is conceptualized as being linked to cultural concepts of health pervasive in contemporary Western societies. However, little is known about the phenomenology and clinical correlates of orthorexia nervosa in non-Western cultures. The current study examined symptoms of orthorexia nervosa, obsessive-compulsive disorder, depression, anxiety, and fear of negative evaluation among 418 Chinese university students. A minority of participants endorsed frequent or impairing orthorexia nervosa symptoms, and females reported slightly higher severity of orthorexia nervosa symptoms than males. Orthorexia nervosa symptom severity was moderately associated with obsessive-compulsive and anxiety symptoms, and weakly associated with depressive symptoms and fear of negative evaluation. Although this study generates initial data about orthorexia nervosa among Chinese students, further research is greatly needed to establish the prevalence and clinical characteristics of orthorexia nervosa in Western and Non-Western cultures.
