Outline of Final Research Achievements

The present study aimed to assess sleep/wake patterns of adolescents with a discrepancy in sleep phases on school and weekend nights, to examine a relationship between the discrepancy and daytime functioning, and to verify the effects of a sleep education program for the adolescents. Students with the discrepancy reported later weekday and weekend bedtimes, less weekday sleep duration, and longer weekend sleep duration than those without it. In a generalized linear mixed model, the discrepancy was associated with insufficient sleep, daytime sleepiness, irritability and poor academic performance. After the post-education periods, the sleep education group significantly improved both in their sleep knowledge and in their sleep-promoting behaviors. Sleep duration were also improved in the sleep education group, and the effect was sustained at 3-month follow-up. The present findings suggest that this sleep education program is effective for improving adolescents’ sleep/wake patterns.
