Disparity in access to bariatric surgery among African-American men.

Abstract

Despite improvements in safety and effectiveness in surgical management of extreme obesity, men and racial minorities are less likely to receive metabolic and bariatric surgery (MBS) compared to other patient groups. This study examines the racial and gender disparities in access to MBS to understand the mechanism that drives these problems and to propose strategies for closing the disparity gap. Using 2013-2014 National Health and Nutrition Examination Survey data, we estimated the proportion of individuals, by race and gender, who were eligible for MBS based on Body Mass Index (BMI) and comorbidity profile. We analyzed the 2015 MBS Accreditation and Quality Improvement Program Participant Use Data File to examine differences in patient characteristics, comorbidities, and postsurgical outcomes among African-American (AA) and White men. Predictors of poor outcomes were identified using unconditional logistic regression models. AA men represented 11% of eligible patients but only 2.4% of actual MBS patients. Compared to White men, AA men were younger, had higher BMI, were more likely to have a history of hypertension, renal insufficiency, required dialysis, and had American Society of Anesthesiologists class 4 or 5 (all P values < 0.01). After surgery, AA men were more likely to suffer from postoperative complications (adjusted odds ratio (aOR) 1.25, 95% confidence interval (CI) 1.02-1.52) and stayed in the hospital for more than 4days (aOR 1.51, 95% CI 1.26-1.82) compared to White men. Despite being eligible for MBS based on both BMI and obesity-related comorbidities, AA men are significantly less likely to undergo MBS. Those AA men who receive surgery are significantly younger than White men but also experience greater comorbidities compared to White men and all women. Further longitudinal studies into patient-, system-, and provider-level barriers are necessary to understand and address these disparities.
