BACKGROUND: 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. OBJECTIVE: The present study was designed to test the hypothesis that at longer term follow-up AAs are just as successful as CAs after LRYGB. SETTING: University hospital, United States. METHODS: 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. RESULTS: 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 model, diagnosis of T2D in the AA group (OR = 6.1 E8) significantly (P = .002) predicted adequate EWL at 3 years, after controlling for relevant confounders. CONCLUSION: Race significantly affected the long-term EWL at 3 years for patients undergoing LRYGB at the authors' institution. Future research should be directed at determining potential genetic reasons for these differences, including genes associated with T2D.
