Outline of Final Research Achievements	In order to improve the sleep habits and mental health of elementary school students, we examined the intervention effect of sleep improvement application. The subjects were 309 elementary school students in Okinawa prefecture, 243 in the intervention and 66 in the control group. The sleep improvement application is bundled with two functions: a sleep diary function that monitors bedtime / wake-up time and other lifestyles, and an e-learning function that learns sleep science / medicine. The sleep diary function provides feedback on sleep improvement advice each of one week, and links related e-learning materials. Before and after the 4-week sleep improvement application intervention, a questionnaire survey was conducted to examine the effect of the intervention. As a result, no significant change was observed in the control group, but in the intervention group, sleep regularity and sleep quality were significantly improved, and self-esteem was also significantly improved.

Academic Significance and Societal Importance of the Research Achievements	日本人は大人も子どもも先進国で最も睡眠時間が短く、睡眠後進国と言われる。本研究は、多くの児童に睡眠を介入するため、ICTを活用した睡眠改善アプリを作成した。睡眠教育に必要な、睡眠行動をモニタリングする睡眠日誌機能で睡眠行動を分析し、睡眠改善のアドバイスのフィードバックを行い、並行してeラーニングによる睡眠の授業を行い、児童の睡眠リテラシーの向上も試みた。その結果、児童は睡眠リテラシーが向上し、エンパワメントされ、睡眠行動が変容し、学力やメンタルヘルスが向上した。日本の児童への睡眠教育のポピュレーションアプローチとして、睡眠改善アプリの有用性のエビデンスが得られたことは学術的意義が大きい。
