Abstract

Rationale : Obesity is pandemic. Eating disorders is one of the causative factors. Obesity surgery offers better long-term outcomes than standard medical therapy. Nevertheless, about 20 to 30% of operated obese patients regain weight. That could be explained in many instances by an insufficient management of preoperative eating disorders including FA. The prevalence of FA is not known in obese patients eligible for obesity surgery. The main aim is to identify the prevalence of FA in a cohort of obese patients eligible for obesity surgery.Methods : FA was diagnosed by the validated questionnaire YFAS 2.0. 246 questionnaires were retrospectively analyzed. Each patient consulting in our centre between June 2016 and March 2018 systematically filled out the YFAS 2.0. FA was classified as absence, low, moderate or severe, according to the recommended questionnaire interpretation.Results : Among 246 patients, mean age was 42.5 years old (+/- 13.6), 195 were women (79%). 131 patients (53%) did not have FA. 67 (27%) patients had FA (mean age, 39.3±12.0 yrs ; women, n=60 (90%)). Among the 67 patients who had a FA, 6 (9%) had low FA, 22 (33%) moderate FA, and 39 (58%) severe FA. 48 (20%) were not classified because of questionnaires that were partially filled in. At ESPEN congress, more data regarding patients’ profile, including obesity-related complications, will be reported.Conclusions : FA is reported in one third of obese patients referred for obesity surgery. Our study highlighted that many patients did not fill totally the questionnaire, and the subjectivity of the results obtained from a declarative questionnaire. This reinforces the idea that objective criteria, e.g. brain functional magnetic resonance imaging, are needed to diagnose FA and best orientate obese patients’ therapy.
