A research group led by Professor Manabu Saito of Hirosaki University Graduate School found that 5% of 18-year-old children have sleep problems, 50.4% of children with autism spectrum disorder (ASD), and 39.8% of children with attention deficit hyperactivity disorder (ADHD). It was revealed that there is.
In recent years, it has become clear that insomnia in children affects not only health problems such as obesity but also physical and mental health, including academic performance, cognitive ability, behavioral problems, and suicide. It is also becoming clear that people with neurodevelopmental disorders (NDS) often have sleep problems. However, there are no studies in Japan or abroad that have investigated in detail the prevalence of sleep problems among preschool children and the influence of family background and lifestyle habits.
研究グループは、2018年と2019年に弘前市5歳児発達健診に参加した5歳児2,055人、2014年と2015年に精密検診に参加した5歳児281名を追加し、合計2,336人を対象として調査した。
They found that 5% of children aged 18 years had sleep problems. In terms of diagnosis, 50.4% of ASD patients and 39.8% of ADHD patients had sleep problems. The prevalence of sleep problems was found to be 5% in 14.8-year-old children without NDS, and 3.4 times higher in children with ASD and 2.7 times higher in children with ADHD.
また、家庭環境では収入200万円未満では30.5％、兄弟姉妹なしで24.2％に睡眠問題があり、生活習慣では就寝時間が22時以降で30.7％、起床時間が7時30分以降で30.7%、睡眠時間が9時間未満で25.3%、入眠遅延が30分以上で35.3%、スクリーンタイムが2時間以上／日で21.1%となり、睡眠障害の有病率が有意に高かった。
Based on the results of this study, the research group pointed out the need for appropriate health guidance. Four lifestyle habits were recommended: falling asleep within minutes (within 21 minutes at the latest) and screen time of less than 22 hours/day.
