Positional Dependency in Asian Patients With Obstructive Sleep Apnea and Its Implication for Hypertension

Abstract

This study demonstrates that the prevalence of PPs among Asians is almost three-fourths of the patients and that the AHI is the most dominant factor for determining positional dependency, followed by BMI. The PP group had lower BMI, a lower AHI, longer deep sleep, longer rapid eye movement sleep, and less daytime sleepiness than did the NPPs. The prevalence of hypertension was also affected by positional dependency.
