Weight Recidivism After Roux‐en‐Y Gastric Bypass Surgery: An 11‐Year Experience in a Multiethnic Medical Center

Objective Weight recidivism following Roux‐en‐Y gastric bypass (RYGB) is common and is associated with recurrence of comorbidities. Studies with long‐term follow‐up of recidivism quantified by weight regain (WR) are lacking. A retrospective review of all RYGB at our center from 2004 to 2015 was performed to examine the effects of race and type 2 diabetes on WR following RYGB. Methods Multivariable linear mixed models were used for the effects of time and race on weight, WR relative to nadir weight (WR/nadir), and WR relative to maximal weight loss, and Cox regressions were used for low, moderate, and high WR/nadir. Results A total of 1,395 participants were identified. The sample was limited to African American (AA), Caucasian American (CA), and Hispanic American (HA) participants. The effects of time (P
