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

Given the importance of preoperative screening for OSA in bariatric surgery and the predominance of female gender in this intervention, the aim of the study was to assess gender-specific performance of four sleep questionnaires. These included the Epworth Sleepiness Scale (ESS), Fatigue Severity Scale (FSS), STOP Bang, and NoSAS to predict moderate to severe OSA in this morbidly obese population. Results demonstrated a gender-specific difference in the performance of the evaluated screening questionnaires. These findings suggest the need for gender-specific OSA screening algorithms in morbidly obese patients.
