REM-related sleep-disordered breathing is associated with depressive symptoms in men but not in women

초록

The purposes of the present study are to determine the prevalence and demographic features of rapid eye movement (REM)-related sleep-disordered breathing (SDB) in Korean adults with newly diagnosed obstructive sleep apnea (OSA) and determine if REM-related SDB is associated with depressive symptoms and health-related quality of life (HRQoL) in OSA patients. In this cross-sectional study, we evaluated 1281 OSA adults who were consecutively recruited. REM-related SDB was defined as an overall apnea-hypopnea index (AHI) aeyen5, an AHI(NREM) < 15, and AHI(REM) to AHI(NREM) ratio of > 2. The Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Medical Outcomes Study Short-Form Health survey (SF-36) were used to evaluate all patients. Multiple regression analyses were performed to determine the associations between REM-related SDB and clinical outcomes. The prevalence of REM-related SDB was 18 % in this study. REM-related SDB was more commonly observed in patients with mild or moderate OSA (p < 0.001) and women (p < 0.001). The linear regression analysis showed that the presence of REM-related SDB was significantly associated with higher BDI scores, but only in men. AHI(REM) was positively associated with the BDI scores, but only in men with REM-related SDB. There were no differences in ESS and SF-36 scores between patients with and without REM-related SDB. Patients with REM-related SDB account for 18 % of Korean OSA adults. REM-related SDB was associated with depressive symptoms, but only in men. AHI(REM) is positively related to the degree of depressive symptoms in men with REM-related SDB.
