Prevalence and characteristics of positional sleep apnea in the HypnoLaus population-based cohort

In this large population-based study, we found that POSA is present in 53% of the middle-to-older age general population, and in 75% of OSA subjects. ePOSA was present in 36% of OSA subjects, suggesting that a large proportion of them could be treated with positional therapy. AHI and BMI were differently associated with POSA in men, and pre or post-menopausal women.
