Polysomnographic, demographic and clinic differences between male and female obstructive sleep apnea patients.

Introduction: The differences between both genders with Obstructive Sleep Apnea Syndrome (OSAS) which is often seen in males can be explained by means of certain polysomnographical parameters and demographical and clinical features. The aim of this research study is to research the gender differences in Turkish population in terms of polysomnographical parameters and demographical and clinical features, and to compare and contrast the results of this research with the results of literature.

Materials And Methods: This study has been carried out by including 100 females and 116 males, 216 patients in total, who were diagnosed with OSAS in the Sleep Laboratory of the Medicine Faculty, Ankara University between the years of 2011 and 2014. The demographical information like the ages and the genders of all patients and the figures of the height, weight and body-mass index (BMI) have been recorded. The Epworth Sleepiness Scale (ESS) of patients have also been recorded. Acquired by the polysomnography equipment, the polysomnographical data of all patients having the criteria of this study have been evaluated.

Result: The average age of female patients, which is 57.2 ± 9.1 (the lowestthe highest), has been found to be meaningfully high (p<0.05) when compared to the average age of male patients (50.9 ± 11.8). The body-mass index (BMI) averages of female patients, which are 35.4 ± 9.2, have been determined to be high (p<0.05) when compared to the body-mass index (BMI) average of male patients (32.5 ± 6.7). The total Apnea Hypopnea Index (AHI) of male patients have been found to be meaningfully higher than of the female patients (p<0.05). Mild and moderate OSAS in female patients have been observed at a higher rate than males. On the other hand, severe OSAS has been observed at a higher rate than females (p<0.05). Likewise, while the average obstructive apnea time in male patients has been for 17 ± 5.8 seconds, the same figure has been for 14.5 ± 4.4 seconds (p<0.05).

Conclusions: As a result, in this study, we have observed that females suffering from OSAS are older and obese at a more rate and they have lower Apnea Hypopnea Index (AHI) than the males with OSAS. We have also distinguished that the symptoms related to OSAS of both genders are similar despite the lower Apnea Hypopnea Index of females. Meanwhile we want to emphasize that clinicians need to take these factors into consideration while focusing on the diagnosis of OSAS in female patients.
