Pneumologia - Journal of the Romanian Society of Pulmonology: Predictors of daytime sleepiness in patients with obstructive sleep apnea


Background. The main symptomatic criterion to diagnose obstructive sleep apnea (OSA) is the level of daytime sleepiness. The Epworth Sleepiness Scale is a simple, self-administered questionnaire which provides a measurement of the subject’s general level of daytime sleepiness.
The aim of this study was to investigate the factors that can predict daytime sleepiness in patients with sleep apnea.
Conclusion. The desaturation index showed the
strongest correlation with the Epworth scale. According to the results of the backward stepwise multiple regression and logistic regression, the predictors for the level of daytime sleepiness are oAHI and index of desaturation. According to the analysis of the ROC curve, desaturation index is a predictor of a high specificity.
