The Influence of Obesity on Different Genders in Patients with Obstructive Sleep Apnea

Abstract EN

Obesity is considered to be a major contributing factor to obstructive sleep apnea (OSA); however, there is limited evidence with regard to gender predominance.

We analyzed 2345 patients (339 females) in correlation with body mass index (BMI) and OSA severity.

Male AHIs were significantly higher than female AHIs in each BMI group.

As the BMI increased, the AHI increased in both males and females, and this trend was more obvious in males.

For BMI-matched male and female patients with OSA, the severity of OSA was higher in males.

As BMI increased, the severity of OSA increased more obviously in males.

Our findings suggest that increased body fat contributes to the pathogenesis of OSA more in males than in females and that obesity plays a more significant role in contributing to OSA in male patients.
