| Research Abstract |
We conducted a multicenter cross-sectional observational survey investigating the prevalence of sleep disorders among inpatients of acute wards. Questionnaire-, actigraph- and observation-based sleep evaluations were simultaneously performed in 557 adult inpatients of acute wards during a one-month period. Of the 421 patients with data available, 22.3% had at least one of the following sleep disorders : sleep apnea syndrome, restless legs syndrome, periodic limb movement disorder and nocturnal behavior disorder. Similarly, 62.7% had insomnia, 6.9% had severe daytime sleepiness and 12.8% had other sleep-related symptoms. Only 13.8% were free of any sleep-related problem.
