Outline of Final Research Achievements

This study was conducted to investigate the association between industrial accidents and sleep-related parameters in factory workers, and to examine the effectiveness of sleep education intervention for improvement of sleep status. 714 factory workers were included in the study. And workers were selected for a sleep education. Then, using data from the follow-up survey, we examined the effectiveness of sleep education by analyzing the differences in the improvement of sleep disorders and sleep habits between the groups who did and did not receive sleep education. We detected a significant association between the occurrence of industrial accidents and PSQI scores from the baseline survey. With regard to the effectiveness of the sleep hygiene education intervention, the percentage of early risers increased significantly in the intervention group among the participants less than 40 years of age.
