OBJECTIVES: Our intention was to investigate the prevalence of Eating Disorder and Body Dysmorphic Disorder in patients diaghnosed with depression, anxietay and borderline personality disorder by gender, using controll groups. METHODS: The reserach was 2009 at the Department of Phsyciatry of Szigetvár Hospital (Hungary). Eating Disorder Inventory was used. A self-made questionnaire aimed the body mass, body height and several demographic data. Inclusion criteria: ones between 18 and 50 years age, and according to BNO F32-F34 (depression), F41 (anxiety), F6030 (borderline personality disorder) diagnoses. Control group: participants with age between 18 and 50 years like that, who do not stand under a psychiatric treatment. The statistical analysis consisted of two sample T test, χ2-probe. RESULTS: The target group's number was 82, the control group 85. In the „The feeling of the insufficiency„(p<0.001), „Interpersonal distrust” (p<0.005), „Interoceptive consciousness” (p<0.001) scales,  the members of the control  group from all three psychiatric patient groups reached a significantly lower score away. In the „Bulimia” scale there was a significantly lower score in the control  group as well than the borderline in a group (p<0.005), and here I found a significant difference between the members of two psychiatric groups: the anxious group reached a lower score, compared with the borderline group (p<0.001). CONCLUSIONS: The three psychiatric patient groups did not attain the threshold value onto one of the eating disturbances relevant scales neither There is not a direct, causal contact between the examined psychiatric clinical pictures.  The men's higher result achieved on the „Bulimia” scale relates rather onto the binge eating disorder.
