Research Abstract	During the past decades, the sleep duration of Japanese has shortened, one of five Japanese adults have suffer from insomnia symptoms. The findings from earlier research in Europe and North America suggest that both short sleep duration and insomnia associate with the incidence of lifestyle-related diseases. However, comparative data are scares in Japan. Therefore, we assessed the association of sleep duration and insomnia symptoms with lifestyle-related diseases in both cross-sectional studies and a large-scale cohort study. Our results suggest that both short sleep duration and insomnia symptoms associate with the incidence of diabetes. To prevent diabetes, we should develop and practice appropriate sleep routines.
