The pathophysiology of sleep-related disorders is likely to be different between women and men. Our group has previously evaluated, in a population of women with a body mass index of > 30 kg/m2, the relationships between EDS, AHI, and snoring. We showed that habitual snoring and EDS were present in 47% and 35%, respectively, of obese women without obstructive sleep apnea (OSA), while women with habitual snoring showed the highest ESS score. Conversely, no correlations were observed among ESS, AHI, body mass index, and body fat distribution. Similar results were also reported by Klink et al,6 who showed that snoring was a significant risk factor for EDS in the general population.
