EPA-0578 - Is orthorexia nervosa an eating disorder an obsessive-compulsive disorder

Abstract

Purpose The aim of this study is to assess the dependence between the obsessive-compulsive symptoms, the eating disorders symptoms and orthorexia in adolescents aged 15-19, due to define which of these areas orthorexia is closer to. The study controlled such variables as: age, sex, BMI, school type. Subjects and Methods The study covered 1899 pupils of secondary schools. The OCD and ED symptoms assessment was carried out with the LOI-CV, EAT-26 and the ORTO-15 questionnaire (two threshold values: ON- 40 and ON -35). The research was financed by scientific grant of Nutricia Foundation. Results Revealed correlations of risk factors of ON - OCD and ON - ED indicated the higher the probability of diagnosis of these disorders, the higher the probability of ON diagnosis, too. The compatibility of ON and OCD diagnoses was for ON-40 = 45.8% and ON-35, 76.5%. It was shown that the OCD increases the risk of ON at the threshold value ON = 35. In the case of ON and ED, the diagnostic compatibility was ON-40, 42.7% and ON-35, 84.4%. The analysis of various variables confirmed a significant dependency of ON from ED, which suggests that ON belongs to ED. The diagnostic accuracy in this case is better at the threshold value ON- 35. Conclusions The results of our study should be confirmed in further research.
