Abstract

Objective: To estimate the prevalence of symptoms of sleep-disordered breathing (SDB) and to evaluate the relationship between these symptoms and concomitant systemic disorders in Turkish adults. Material and Methods: A sample group representing whole Afyon city filled, a questionnaire consisting of questions about demographic features, SDB symptoms and concomitant diseases. Body mass indices of the subjects were calculated. Results: There was no significant difference for snoring between males and females, whereas witnessed apnea and excessive daytime sleepiness were significantly higher in females. Obesity was more prevalent among females. SDB symptoms were more common among obese subjects. Diabetes (DM), hypertension (HT), hyperlipidemia and congestive heart failure (CHF) were significantly more prevalent among snorers. There was a 1.7 folds increase in HT risk and a 1.4 folds increase in DM risk in snorers. We also found a 1.4 folds increased risk for hyperlipidemia and 2.1 folds increased risk for CHF in our snorer population. Snoring and witnessed apnea were found as risk factors for hypertension independently from smoking status. BMI and age. Conclusion: The frequency of SDB symptoms were high in Afyon city, with a greater than expected rate for females. Snoring and witnessed apnea were found as independent risk factors for hypertension.
