Earlier this week we deposited data from the Apnea, Bariatric surgery, and CPAP (ABC) study in the National Sleep Research Resource. ABC aimed to assess the role of bariatric (weight loss) surgery as compared to continuous positive airway pressure (CPAP) therapy plus weight loss counseling for the treatment of patients with class II obesity and those who have severe obstructive sleep apnea (OSA). 49 subjects were randomized into the trial, with 43 being followed up at 9-months and 40 at 18-months.
ABC was supported by NIH grants R01HL106410 and K24HL127307. Philips Respironics donated the CPAP machines and supplies used in the perioperative period for patients undergoing bariatric surgery.
