Sex differences in a self-report questionnaire related to obstructive sleep apnea: An online cross-sectional survey

The impact of reported fatigue on the prevalence of OSA is substantial among males but non-significant among females. The efficacy of daytime sleepiness scales in evaluating OSA is poor. The fatigue scale may be more effective in the screening of OSA, at least in males. Limitations of the study include potential response bias due to participant anonymity and the use of the STOP-Bang Questionnaire instead of polysomnography, the gold standard for OSA diagnosis.
