Objectives: To investigate whether a history of body injury is associated with obstructive sleep apnea (OSA) in patients with rapid eye movement (REM) sleep behavior disorder (RBD).
Methods: We enrolled 56 consecutive patients with RBD, a history of dream-enacting behaviors, and polysomnographic evidence of REM sleep without atonia. Participants were asked whether they had any history of body injuries such as self-injury or bed-partner injury during sleep. The demographic characteristics and polysomnographic parameters of the groups with a history of injury (n=34, 60.7%) and without (n=22, 39.3%) were compared. The association between the history of injury and OSA was assessed.
Results: OSA [apnea-hypopnea index (AHI) ≥5/h) was associated with a history of body injury [odds ratio (OR)=6.25, 95% confidence interval (CI)=1.64?23.84]. Additionally, the logistic regression analysis showed that insomnia severity index (OR=0.87, 95% CI=0.80?0.98) and AHI (OR=1.10, 95% CI=1.02?1.18) were associated with history of body injury.
Conclusions: Therefore, we can conclude that history of body injury is related to obstructive sleep apnea in patients with RBD.
