BODY-Q patient-reported outcomes measure (PROM) to assess sleeve gastrectomy vs. Roux-en-Y gastric bypass: eating behavior, eating-related distress, and eating-related symptoms

Background Post-operative changes in eating behavior, eating-related distress and eating-related symptoms play an important role in the lives of bariatric surgery patients. However, there are no studies that assess these outcomes using a specifically designed patient-reported outcome measure (PROM) for patients undergoing bariatric surgery. We use our newly developed and validated scales as part of the well-established BODY-Q PROMs to compare laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass patients (LRYGB). Methods We analyzed data from an international multi-center prospective cohort study of patients over 18 who underwent bariatric surgery. We used multivariable linear regression models to assess the difference between LRYGB and LSG for the new BODY-Q scales, which include eating behavior, eating-related distress and eating-related symptoms. All analyses were corrected for significant confounding variables. Results Out of 1420 patients, 920 underwent LRYGB and 500 underwent LSG. The LRYGB group had a higher percentage total weight loss ( p
