The influence of gender on symptoms associated with obstructive sleep apnea

Background

It has been reported that the clinical expression of obstructive sleep apnea (OSA) may differ in women and men.

Objective

The objective of this study was to evaluate the influence of gender on reported OSA-related symptoms in a large clinical population of patients.

Methods

The database from the sleep laboratory of a tertiary care center was examined. Adult patients who had undergone a diagnostic polysomnography and completed the Berlin questionnaire, a sleep questionnaire, and the Epworth sleepiness scale were selected. Multiple logistic regression analysis was performed to assess the relationship between OSA-associated symptoms and different potential explanatory variables.

Results

The study sample included 1084 patients, median age was 53 years, 46.5% (504) were women, 72.7% (788) had OSA (apnea/hypopnea index ≥?5), and 31.2% were obese. After adjusting for age, body mass index, and apnea/hypopnea index, men were more likely to report snoring (OR 4.06, p?p?p?p?p 0.001), sleep onset insomnia (OR 0.59, p 0.0035), and morning headaches (OR 0.32, p?

Conclusion

Women with OSA were more likely to report tiredness, initial insomnia, and morning headaches, and less likely to complain of typical OSA symptoms (snoring, apneas) than men.
