Objectives:
to assess the prevalence of obsessive-compulsive disorder (OCD) or OC symptoms in patients with anorexia nervosa (AN) and to find a possible relationship between presence of OC symptoms and course of AN.

Methods:
137 adolescent female patients with AN, aged 14,8 +/- 1,8 years, completed the Polish version of the LOI-CV. Two groups, High-risk (HR) and no High-risk (nHR), were defined according to the cut-off score of LOI-CV. The diagnosis of OCD was confirmed with the Polish version of K-SADS-PL. The relationship between number and intensity of OC symptoms and following data were analyzed: age of onset and on admittance to a psychiatric facility, weight loss, BMI on admittance and its changes, age of first menstruation, time of amenorrhea and of restitution of menses, length of treatment and number of relapses.

Results:
OCD was not diagnosed in any subject, but 25% had OC symptoms which qualified them to High-risk group. Differences in HR and nHR groups were found between duration of AN before hospitalization, age and body mass after release from hospital. Negative correlation was found between “Yes” Score and Interference Score in LOI-CV and the age of patient at the time of release from hospital.

Conclusions:
the results of our study do not support the observations about a high co-occurrence AN and OCD, but indicate the frequent co-occurrence of OK symptoms.
