Outline of Final Research Achievements

Elementary school students were surveyed regarding their sleep status and factors related to their daily lives. A total of 126 participants (63 boys and 63 girls) were analyzed. The average nighttime sleep duration of the participating students was 9 hours 18.8 minutes (±24.3 minutes) The 2-week survey was divided for analysis into two groups: those who woke up on their own (spontaneous awakenings) more than 8 days and those who woke up less than 7 times. In the group with more than 8 days of spontaneous awakenings the most students used smartphones for 0 hours, while in the group with less than 7 days the most students used smartphones for 2 hours or more. A relationship between smartphone use and children's sleep rhythms was suggested.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的問いは、子ども達の睡眠にとって必要な「環境要因」は何かである。子ども達の睡眠時間が年々短くなる現代、個人から環境レベルに視野を広げて、子ども達の睡眠を考える必要がある。子ども達の睡眠に障害が生じる環境要因は何か、睡眠の不足した子ども達の心身がどのように発達していくかについて、調査を行う。研究結果を通じて、子ども達の睡眠と環境整備の必要性、またその具体的方策を社会に向けて提言する。さらに、地域医療として木津川市の子どもの睡眠衛生改善を行い、行政と共に子どもの睡眠環境のモデル地区を目指す。
