Health disparity in access to bariatric surgery

Abstract

Background: Sociodemographic disparities in terms of access to bariatric surgery are ongoing.

Objectives: This study aimed to examine the trends for bariatric interventions based on patient characteristics from 2011 to 2018 in the state of New York.

Setting: Administrative statewide database.

Methods: This study used the New York Statewide Planning and Research Cooperative System database to identify all patients with obesity who underwent Roux-en-Y gastric bypass (RYGB), laparoscopic sleeve gastrectomy (SG), and laparoscopic adjustable gastric banding (LAGB) between 2011 and 2018. The trends were studied for the types of bariatric procedures performed across different patient characteristics, including median household income as determined based on ZIP code. A multivariable logistic regression analysis was performed to compare the yearly trends.

Results: We identified 111,793 patients who underwent bariatric surgery. The number of bariatric procedures increased from 9304 in 2011 to 16,946 in 2018. RYGB was the most performed bariatric operation in 2011, but was replaced by SG from 2013 to 2018. Patients living in the highest decile median household income ZIP code areas had the highest increase in SG (odds ratio [OR], 1.51; 95% confidence interval [CI], 1.46-1.55; P < .0001) and the largest decrease in LAGB (OR, .53; 95% CI, .51-.56; P = .0007).

Conclusions: The use of bariatric surgery increased significantly from 2011 to 2018. However, the disproportionately and substantially increased use of SG and the decreased use of LAGB in patients living in wealthier areas suggest that disparity in the use of bariatric interventions still exists. Public health efforts should be made to equalize access to bariatric surgery.
