In obstructive sleep apnea (OSA), severity of individual obstruction events is connected to increased mortality rate and it can be significantly different in patients with similar apnea-hypopnea index (AHI). However, possible gender-dependent variation in severity of obstruction events in different OSA categories is unknown. We investigated whether the severity of obstruction events differs between genders with similar AHI and if this difference varies between OSA categories.

Polygraphic recordings of 2057 consecutive patients with suspected OSA were reanalyzed and those with AHI ≥5/h were included for further analysis (n _male = 893 and n _female = 197). Statistical significance of differences in AHI, apnea index, hypopnea index, oxygen desaturation index, obstruction severity parameter, and severity of …
