Is Orthorexia Nervosa a Non-specific Eating Disorder or a Disease in the Spectrum of Obsessive-Compulsive Disorder?

In recent years, there has been a dramatic increase in awareness in society that healthy nutrition has positive effects on health. However, obsession with these behaviors towards healthy foods causes negative effects on health and quality of life. The aim of this study was to elucidate the relationship between the incidence of orthorexia nervosa (ON) in medical school students and the level of conscious awareness, obsessive-compulsive disorder, eating attitudes and behaviors, health anxiety, and body image to clarify the unclear issues in the literature, such as whether orthorexia nervosa is among the psychological disorders, "where" it will take place, and which diagnoses it can be associated with. Students between the 1 and 6 grades of medical school were invited to participate in this research. The Sociodemographic Data Form, Maudsley Obsessive-Compulsive Question Index (MOCI), Eating Attitude Test Short Form (EAT SF-26), Health Anxiety Inventory-Weekly Short Form (HAI-SF), ORTO-11 scale, Body Perception Scale, and Conscious Awareness Scale have been applied to the students. In univariate analysis, the eating disorder scale, body image scale, and awareness scale total scores all had an impact on orthorexia. Each increase in the eating disorder scale score increased the diagnosis of orthorexia 1.07 times, while each increase in the body image scale score increased the diagnosis of orthorexia 1.09 times. Additionally, each increase in the conscious awareness scale score decreased the diagnosis of orthorexia by 0.92 times. When all variables were re-evaluated in the multivariate analysis, it was seen that the total scores of the body image scale and conscious awareness scale affected the diagnosis of orthorexia. There was a weak inverse relationship between the orthorexia scale score and only the health anxiety inventory total score (p
