Prevalence and Prediction of Obstructive Sleep Apnea Prior to Bariatric Surgery-Gender-Specific Performance of Four Sleep Questionnaires.

Bariatric surgery is a treatment option for morbid obesity leading to substantial and sustained weight loss in adults. The authors sought to assess the gender-specific performance of four sleep questionnaires (Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS), STOPBang, and NoSAS) to predict moderate to severe OSA in the morbidly obese population. They conclude that patients scheduled for bariatric surgery, a gender-specific difference was observed in the performance of the evaluated OSA screening questionnaires. This needs to be considered when these questionnaires are used. They suggest that there is a need for better gender-specific OSA screening algorithms in morbidly obese patients.
