Prevalence and predictors of obstructive sleep apnea in snorers without excessive daytime sleepiness

Abstract

Introduction Obstructive sleep apnea (OSA) can be presented by diverse phenotypes with or without excessive daytime sleepiness (EDS). The present study was conducted to detect the prevalence and the predictors of OSA in a sample of habitual snorers without EDS nor nocturnal observed apnea. Patients and methods A total of 61 adult participants complaining of habitual snoring were included in the study and subjected to OSA screening questionnaire, anthropometric measures, tonsil examination, modified Mallampati score, and full polysomnography. Univariate analysis and regression analysis were done to detect the association of OSA with participants’ characteristics and polysomnography data. The statistically significant variables were entered into the receiver operating characteristic curve to estimate the best cutoff values for predictors of OSA in habitual snorers. Results The studied patients were divided into two groups: 11.5% had no OSA [apnea–hypopnea index (AHI)43 years), obese (BMI >37 kg/m2), and male patients.
