  "abstract": "Introduction Obstructive sleep apnoea (OSA) is highly prevalent in the general population, this is in parts due to a rise in obesity. It remains difficult to achieve substantial weight loss with conventional measures, however, bariatric surgery has been shown to reliably reduce significant weight. Ethnicity is an important factor that has been described to impact healthcare delivery and clinical outcomes. The objective of this study was to compare immediate and perioperative outcomes between black and white patients diagnosed with OSA undergoing bariatric surgery.Methods and Patients We reviewed the data of patients who were screened for OSA using sleep studies as part of the pre-bariatric surgical pathway between 2017–2025 in a large tertiary referral centre (NHS; Guys and St Thomas). Data were collected from the electronic patient records (EPIC); we recorded demographics, ethnicity, and postoperative outcomes (length of stay, complication rates and weight loss at 12 months). Differences were tested using Shapiro-Wilk, Independent T-test and Chi-square and presented as mean (SD) or median (IQR 25th – 75th). Level of significance was chosen as p<0.05.Results We screened 831 patients and due to incomplete datasets, we included 245 patients in the analysis. Of those 174 were white (54 ± 12 Years, 121Females and 49 Males, 49.2 ± 8.3 Kgxm 2) and 71 Black (52 ± 10 Years (p=0.22), 67Females and 4 Males (p=0.001) and 46.7 ± 7.0 Kgxm2(p=0.02)). The length of postoperative hospital stay was shorter (2 IQR 2–3 vs 4 IQR 2–5 p=0.001). Although the absolute rate of complications was similar between the groups (9.8% vs 9.8% p=0.97), white patients experienced less severe complications (e.g., infection) while black patients had more severe complications (e.g, retained needle in situ). At one year follow up, more White patients attended the appointment (46.0 vs 33.8% p=0.19)),had more significant weight-loss (-30.1% IQR -22.4- -38.7% vs -26.3% IQR -20.1- -34.9%, p= 0.04), and lost 3.4% more of their baseline weight on average.Conclusion Black patients experienced less favourable peri and postoperative outcomes following bariatric surgery. These findings highlight potential disparities in the operative care of patients with different ethnicities and raises questions how to improve on these outcomes.",
