Abstract

Previous studies from different countries have shown that ethnic diversity may have an important effect on clinical outcome following bariatric procedures. Israel has an ethnic diverse population but there is limited information about this effect on surgery outcome. We carried out a 3-year institutional, prospective comparative data collection study among Jewish and Arab patients in Israel undergoing primary bariatric surgery. Percent of total weight loss (%TWL) and change in body mass index (BMI) were assessed. The results revealed no difference between Arab and Jewish participants in %TWL nor BMI change. Differences in absolute BMI values were all accounted for by the initial between-group difference in the pre-operative BMI. Comorbidity resolution at 1 year post-surgery was not significantly different between the groups.
