Abstract:

Purpose: To document the clinical characteristics of rapid eye movement (REM)- related obstructive sleep apnea (OSA) and supine-only OSA and identify the effects of sleep state and posture in each subtype. Method: In this cross-sectional study, we evaluated 967 OSA adults. REM-related only OSA was defined as 1) an overall apneahypopnea index (AHI) ≥5/h; 2) a AHI REM to AHI NREM ratio >2; 3) a AHI NREM <15/h regardless of positional tendency and 4) not fulfill the criteria of positional OSA. Positional-only OSA was defined as: 1) overall AHI ≥5/h; 2) supine AHI to non-supine AHI ratio >2; 3) non-supine AHI <15/h and 4) not fulfill the criteria of REM-related OSA. And, fitting to both the criteria of REM-related and positional OSA was REM-related with positional OSA subtype. To compare demographic, clinical, and polysomnographic features among the three subtypes of OSA. Result: Of the 967 patients, 36 (5.7%) and 460 (73.2%) fulfilled the criteria for REM-related only and positional only OSA. REM-related only OSA had higher proportions of women (38.9%) and BDI scores ≥10 (63.9%). Patients with positional-only subtype had the most severe sleep apnea and the worst sleep architecture. In patients with REM-related only OSA, the effects of sleep posture were larger during REM sleep, and the effects of sleep state were also larger during supine sleep. However, in positional-only OSA, the postural effects regardless of sleep state were larger than the sleep state effects. Conclusion: REM-related only OSA, positional-only OSA and REM-related with positional OSA subtype have different clinical characteristics. The effects of sleep state and posture were similar in REM-related OSA. However, the effects of sleep posture were significantly larger than the sleep state effects in positional OSA.
