ABSTRACT
Bariatric surgery is a crucial intervention in managing obesity and related conditions. However, weight loss outcomes can vary significantly, and social determinants of health (SDoH) at the community level may play a role. Our objective is to identify community-level SDoH factors associated with reduced weight loss after bariatric surgery. We conducted an analysis of electronic health records and the social vulnerability index (SVI) of 3,800 patients who underwent bariatric surgery at Vanderbilt University Medical Center. We measured the associations between SVI social factors and the percent change in body mass index three months after surgery using linear regression. The SVI factors with a false discovery rate-adjusted p-value < 0.05 were deemed significant. Statistical results show that patients who reside in communities with racial minority groups or lower insurance rates had reduced weight loss three months after surgery.
