Excessive daytime sleepiness (EDS) is one of the principal symptoms of a sleep disorder, and is often associated with serious consequences including traffic and industrial accidents, decreased productivity and interpersonal problems. However, there are few epidemiological studies on EDS in a large scale sample targeting Japanese general population. Therefore, this cross-sectional study was conducted to evaluate the prevalence rate of EDS and to examine the relationship between sleep problems, insomnia symptoms and EDS in a sample of the general adult population of Japan. The survey was performed using self-administered questionnaire in June 2000, targeting a population randomly selected from among 300 communities throughout Japan. This questionnaire included information about sleep habits such as sleep duration, symptoms of insomnia and underlying disease. A total of 28714 subjects completed the questionnaire. The prevalence rate of EDS was 2.5% (male=2.8%, female=2.2%). Multiple logistic analysis showed that the following were associated with EDS: male sex, young age, short sleep duration, subject insufficient sleep, loss of deep sleep, disagreeable sensations in the legs, interruption of sleep by snoring or dyspnea, and psychiatric stress. Interruption of sleep by snoring or dyspnea was the strongest predictor of EDS. And it is considered to be a typical symptom of sleep apnea syndrome. These findings may be useful in attempts to prevent EDS in the general population of Japan.

Learning Objectives:

• To explain the related factors of excessive daytime sleepiness among Japanese general population
