Introduction: The quality of sleep plays a serious role in the individual's daytime performace and state of health, there by it has a strong influence on the society.
Aim: The present study measures the probability developing and severity of obstructive sleep apnea syndrome, - which belongs to group of disorders of the respiratory - through odds ratio of leading risk factors.
Method: 127 persons were examined in the test. The sleep structure test data were processed by polysomnographic screening device.
Results: The nutritional level of body in mass index (BMI), and the neck circumferences data were recorded in cm. On the basis of the examination the gender as a risk factor it can be said that the odds ratio for men compared to women, more than three times higher of emergence of disease.
Conclusions: Men's chance of the emergence of serious disease is more than four times higher than women's chance. In the men's test group the most significant predictor of obstructive sleep apnea amongst the risk factors is the circumference according to odds ratio. In women's group the leader odds ratio is BMI. More than 50% of test goup don't report about daytime sleepiness, and this fact draws our attention to the role of risk factors' odds ratio in selection. Orv Hetil. 2017; 158(21): 823-828.
