- Abstract
- Background and Objectives:Obstructive sleep apnea (OSA) patients are classified into positional patients with supine apneahypopnea
index (AHI) that is at least twice as high as the non-supine AHI, and non-positional patients with a supine AHI that
does not reach double values of the non-supine AHI. We determined the prevalence of positional sleep apnea and compared clinical
characteristics between positional and non-positional OSA patients. Subjects and Method:This was a cross-sectional study
at a tertiary rhinologic referral center. We evaluated 113 patients whose AHI were over 5 and whose sleep time of supine, nonsupine
position were over 15 minutes as a result of overnight polysomnography taken from January 2007 to July 2008. The body
position of patients was confirmed with sleep position sensor and direct observation. Results:Positional sleep apnea was seen
in 14/22 (63.64%) with mild sleep apnea (AHI, 5 to 15/h), 16/36 (44.44%) with moderate sleep apnea (AHI, 15 to 30/h), 14/55
(25.45%) with severe sleep apnea (AHI, ≥30/h) and over all prevalence of positional sleep apnea in this study is 38.9%. The
severity of OSA, weight, waist and waist to hip ratio (WHR) is related to the positional tendency. Conclusion:The result of
this study revealed that positional sleep apnea was more common in patients with mild OSA and the positional tendency of OSA
patients was affected by central obesity.
