Abstract

OBJECTIVE: To study the prevalence of all relevant eating disorders in 157 obese patients waiting for bariatric surgery. Another aim was to explore for possible differences between gender, and those with and without ED. The dependent variables were: socio-demographic characteristics, BMI, obesity onset, and obesity-related somatic diseases. METHODS: ED was assessed using the self-report questionnaire, “Eating Disorders in Obesity” (EDO). The patients answered a questionnaire that targeted socio-demographic and health information. RESULTS: Subgroups were based on the patients responses to items on the EDO: 1 patient (0.6%) with Bulimia Nervosa (BN), 6 (3.8%) with Eating Disorder Not Otherwise Specified (EDNOS), 21 (13.4%) with Binge Eating Disorder (BED), and 23 (14.6%) with Binge Eating (BE). The patients in the EDNOS group were those who lacked one criterion of the BN diagnosis. The patients in the BE group lacked one criterion of the BED diagnosis. Twenty-eight (17.8%) fulfilled the DSM-IV-TR criteria for ED. When patients with BE were added, 51 patients (32.5%) were identified with ED or sub-threshold ED. In the explorative part of the study, no gender differences in socio-demographic variables, BMI, obesity onset, and obesity-related somatic diseases emerged. With the exception of age, no differences were found in these variables between those with and without ED. CONCLUSION: Employing all relevant eating disorders and binge eating symptoms (BE) for this population identified patients with pathological eating behaviors, which are not detected in previous studies measuring only BED and BE.
