Abstract
Study Objectives: This study determined the prevalence of rapid eye movement-related sleep-disordered breathing (REM-SDB) in the general population, and investigated the associations of REM-SDB with hypertension, metabolic syndrome, diabetes and depression.
Methods: 2074 home polysomnography (PSG) recordings from the population-based HypnoLaus Sleep Cohort (48.3% men, 57±11 years old) were analysed. The apnoea–hypopnoea index was measured during REM (REM-AHI) and non-REM (NREM-AHI) sleep. Regression models were used to explore the association between REM-SDB and hypertension, diabetes, metabolic syndrome and depression in the entire cohort and in subgroups with NREM-AHI<10/h and total AHI<10/h.
Results: Prevalence of REM-AHI≥20/h was 40.8% in the entire cohort. An association between increasing REM-AHI and metabolic syndrome was found in the entire cohort and in both subgroups (p-trend=0.014, <0.0001 and 0.015, respectively). An association was also found between REM-AHI≥20/h and diabetes in both NREM-AHI<10/h (OR=3.12 [1.35–7.20]) and AHI<10/h (OR=2.92 [1.12–7.63]) subgroups. Systolic and diastolic blood pressure were positively associated with REM-AHI≥20/h.
Conclusions: REM-SDB is highly prevalent in our middle-to-older age sample and is independently associated with metabolic syndrome and diabetes. These findings suggest that an increase in REM-AHI could be clinically relevant.
