Characteristics of Patients Undergoing Bariatric Surgery in an Inner-City Minority Population: A Pre and Postoperative Comparison Between Patients With and Without Obstructive Sleep Apnea

Background Obese patients are at an increased risk of obstructive sleep apnea (OSA). Bariatric surgery or weight loss surgery is an important therapeutic measure in obese patients for the management of weight and comorbidities. Data are scarce in inner-city Hispanic and Black patients who undergo bariatric surgery, which eventually leads to health disparity in this minority population. Differences between patients with and without OSA have not been assessed in this population. This study aims to answer these questions. Methodology The study was conducted in a high-volume hospital in the Bronx, New York. Before bariatric surgery, patients underwent a preoperative evaluation that included a variety of blood tests, a sleep study, esophagogastroduodenoscopy, and echocardiography. They also underwent basic anthropometric measurements, such as weight, height, and body mass index (BMI), before surgery and 6 months and 12 months postoperatively. Additional calculations were made using these anthropometric measures, namely, total weight loss, excess weight loss, and delta BMI. Results Most patients were Hispanic (85.2%), with a mean age of 41.9 +/- 10.8 years. We found that of the 108 patients included in the study, 69.4% (70/108) had OSA. Preoperative BMI in the study was 43.9 +/- 13 kg/m2. 2 . Postoperatively, the mean decrease in BMI was 12.3 +/- 14.5 kg/m2. 2 . Total weight loss and excess weight loss were 30.2 +/- 14.3 and 52.6 +/- 16.6, respectively. Conclusions In this study, no significant difference was noted in patients with or without OSA in either the laboratory or anthropometric parameters.
