Outline of Final Research Achievements

To examine the efficacy of a remote support system providing sleep behavior therapy for university students with increased Social Jetlag (SJL), a randomized controlled trial was conducted by recruiting university students with SJL 60 minutes or more. The intervention group received a 2-week intervention providing sleep extension therapy via web content and email. The control group recorded their sleep. The primary outcome was the mean change in SJL. 26 of the 54 participants were assigned to the intervention group and 28 to the control group. The mean change in SJL after 2 weeks was statistically significant between the two groups (27.7 min, P=0.048), indicating the efficacy of the intervention program for university students with increasing SJL.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、社会的ジェットラグの増大に対して、遠隔で行うことができる睡眠行動療法プログラムの介入効果を初めて示した研究である。社会的ジェットラグに着目した睡眠改善により、睡眠だけでなく精神的健康の改善の可能性が示唆され、思春期の睡眠衛生および精神的健康の病態理解を深めることにも寄与する。
