Abstract

Introduction: The Middle Eastern and North African population (MENA) in the US comprises 3.8 million individuals. This study aims to elucidate healthcare outcomes for MENA patients compared to non-MENA patients undergoing bariatric surgery in Michigan. Methods: This retrospective cohort study utilized 2017 - present data from the Michigan Bariatric Surgery Collaborative (MBSC) database. The self identified MENA group comprised 839 patients (1.5% of the total cohort). Data included demographics, comorbidities, procedure performed, 30-day complications, and 1-year postoperative outcomes including weight loss and changes in comorbid status. The analysis included adjusted outcomes using logistic regression and comparisons using chi square or Fisher's exact test were indicated. Results: Compared to non-MENA patients, MENA patients were more likely to be males (25.6% vs 18.6%; p < 0.0001), present at younger ages (age < 30 years: 21.8% vs 11.0%, p < 0.0001), and have a lower initial body mass index (BMI, kg/m2: 45.0 vs 47.4, p < 0.001). There were no differences in 30-day complications (6.2% vs 5.9%, p = 0.586), although MENA patients had lower rates of ED visits (6.3% vs 7.0%, p = 0.017) and healthcare utilization (8.8% vs 9.9%, p = 0.034). Overall, there were no differences in weight loss outcomes or rates of comorbidity improvement at 1 year. Among MENA patients undergoing gastric bypass specifically, percent total weight loss (%TWL) was lower than non-MENA patients (30.1% vs 33.4%, p = 0.008). Conclusion: MENA individuals tend to pursue bariatric surgery at a younger age and at a lower BMI. Bariatric surgery appears to be equally safe and similarly effective in this patient population.
