Outline of Final Research Achievements

First, we investigated the sleep hygiene that affects sleep in high school students. i.e, consuming caffeine at night (RR=2.2) and using a smartphone while sleeping (RR=3.0) were risk factors of sleep disturbances)
Next, a randomized controlled trial (RCT) of sleep intervention focusing on sleep hygiene was performed on high school students with sleep disturbance and absenteeism. As a result, sleep disturbance and absenteeism were significantly improved in the intervention group, and the number of dropouts was also significantly reduced.
This study has revealed that absenteeism and dropouts of high-school students can be improved from the perspective of sleep.

Academic Significance and Societal Importance of the Research Achievements

学生の心身の成長や健康、学業の達成や就学継続は、本人の人生のみならず、社会全体の成長や治安、疾患罹患にも関係する、公衆衛生上の重要な課題です。
本研究の成果は、学生の欠席や学校不適応、そして退学を、睡眠という観点から改善させることができることを示し、そしてその具体的な方法についても明確にしたものです。
この、「科学的根拠に基づく睡眠改善とその効果」について示した本研究は、社会的意義の大きいものであると考えられます。
