Objectives: To determine the prevalence of obstructive sleep apnea (OSA) in extremely overweight adolescents and to examine the effect of significant weight loss on OSA severity. Research Methods and Procedures: We reviewed the anthropometric and polysomnographic data on all extremely overweight adolescents who underwent laparoscopic Roux en Y gastric bypass surgery at Cincinnati Children's Hospital Medical Center from July 2001 to September 2004. Repeat polysomnograms were performed after significant weight loss. Comparisons were made between pre- and postoperative polysomnographic data. Results: Nineteen of 34 patients (55%) who underwent bariatric surgery were diagnosed with OSA. Subsequent to surgery, 10 of these patients returned for follow-up polysomnographic testing. After significant weight loss (mean, 58 kg), OSA severity markedly decreased in all patients (median apnea-hypopnea index at baseline vs. after weight loss, 9.1 vs. 0.65). Discussion: Our study indicated that OSA was highly prev aient in extremely overweight adolescents meeting eligibility criteria for bariatric surgery. The significant weight loss after gastric bypass was associated with a marked reduction in OSA severity.
