| Outline of Final Research Achievements |
Although, sleep is important the physiological mechanism for development brain, the sleep problems until three years old increase risk later development (Touchette E, et al., 2007). Children with neurodevelopmental disorders (NDD) often have more sleep problems than children with typical development (Mindell, & Owens, 2015). In addition, the sleep problems in infancy are important risk factors of difficulty child care (Morgenthaler TI, 2006), and it cannot deny the danger leading to child abuse. We revealed that the difference of the sleep until three years old, which influence later development, of the children with NDD group and the children with non-NDD group through their caregiver's reminiscences.

| Academic Significance and Societal Importance of the Research Achievements |
インタビュー調査の結果、3歳までの子どもの睡眠についてNDD群は非NDD群に比して、乳幼児期から子どもの睡眠に関して多様な困難さを抱えている養育者が多いだけでなく、その困難さの内容や程度も非NDD群とは大きく異なるものであることが示唆された。
本研究で明らかになった困難さについて、乳幼児健康診査やかかりつけ医受診時に、【夜泣き】や【寝つきの悪さ】と言ったフレーズにとどまらず、その内容についても詳細に聞き取りを行うことにより、睡眠の問題に加えて、子どもが抱える発達の偏りの早期の気づき、ひいては虐待予防につながる可能性も示唆された。
