Background The evidence is insufficient for the association between the exposure of sleep disorders and the risk of injury. The aim of this study was to examine the association between patients with sleep disorders and the risk of injury.

Methods This was a population-based retrospective cohort study using Taiwan National Health Insurance Research Database from 2005 to 2010. A total of 15 109 patients with sleep disorders were identified as the study cohort. The non-sleep disorders control cohort comprised 29 955 age- and sex-matched patients. We conducted a Cox proportional hazard regression analysis to estimate the effects of sleep disorders on the risk of injury.

Results The overall incidence of injury was 77.03 per 1000 person-years for patients with sleep disorders, which was significantly higher than that of the control cohort (60.63 per 1000 person-years). Overall, patients with sleep disorders had a higher risk of injury compared with control cohort (adjusted HR=1.27, 95% CI 1.26 to 1.28). Comparing to the control cohort, patients with insomnia had a 12% higher risk for injury (adjusted HR, 1.12 (95% CI 1.01 to 1.41)).

Conclusions Comparing to patients with non-sleep disorders, patients with sleep disorders had a higher risk of injury and the risk was particularly pronounced in those who had insomnia.
