BACKGROUND: To evaluate late meal patterns in patients after Roux-en-Y gastric bypass surgery and to compare sex gender differences. METHODS: From July 2006 to July 2007, patients from the outpatient Londrina Hospital State University - Digestive Surgery Section were evaluated after at least 12 months post-operatively. The patients were studied through a questionnaire, including demographic items about eating behavior, meal pattern, and frequency of vomiting and dumping symptoms. Statistical analysis was performed using Chi-square or Fischer test with significance requiring p<0.05. RESULTS: Data were collected from 116 patients, 95(78.4%) were women and 25(21.5%) were men. There were small differences when comparing women and men in eating behavior, meal pattern, frequency of vomiting and dumping symptoms and no statistical significance was found. Only the variables of fruits intake and somnolence were significantly more frequent in women. CONCLUSION: Applying the proposed questionnaire it was possible to know the late eating behavior and meal pattern of our patients. The intake of fruits was the unique item with statistical differences between genders.
