Abstract Background Previous studies have reported better weight loss after bariatric surgery among non-Hispanic whites (NHW) versus non-Hispanic blacks (NHB) and Hispanics. The majority of these studies took place in areas where NHW are the majority. This study aimed to compare post-surgery weight outcomes by ethnicity in a geographic area where Hispanics are the majority. Methods A retrospective medical chart review of 3268 patients (1561 Hispanic, 660 NHB, and 1047 NHW) who underwent Roux-en-Y gastric bypass (RYGB) or Adjustable Gastric Band (AGB) placement from 2002 to 2012 were analyzed. Percentages of excess weight loss (EWL) and body mass index (BMI) changes at 6, 12, and 24 months postsurgery were compared by ethnic group.
