Abstract

Laparoscopic Roux-en-Y gastric bypass (LRYGB) provides sustained weight loss. However, short-term studies have suggested that African Americans (AAs) are not as successful as Caucasians (CAs) after LRYGB. The present study was designed to test the hypothesis that at longer term follow-up AAs are just as successful as CAs after LRYGB. University hospital, United States. A nested case-control study designed to examine the effect of race as covariate in the long-term success of women undergoing LRYGB. The study matched 3 controls per case subject, and the final numbers for analyses were 78 case patients (AA) and 204 control patients (CA). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression analysis. The 2 cohorts (N = 282) were well matched for age (AA 40.3±9.1 years versus CA 41.1±8.9 years), preoperative body mass index (AA 50.6±7.5 kg/m(2) versus CA 50.2±7.1 kg/m(2)), prevalence of type 2 diabetes (T2D) (AA 20.5% versus CA 21.1%), hypertension (AA 69.1% versus CA 52%), and sleep apnea (AA 35.9% versus CA 34.8%). In the AA group, the long-term curve for percentage of excess weight loss (EWL) was significantly (P<.001) lower than the CA group at any time-point. In the present...Continue Reading
