| Outline of Final Research Achievements |
This study examined preterm infants' sleep development during NICU/GCU hospitalization to one year after birth. We examine quiet sleep, active sleep, and wakefulness during their first one year.
During hospitalization, it was recognized decrease of Active sleep (REM sleep) , increase of Quiet sleep (NREM sleep) , and self-soothing ability. The sleep developed over time, and the circadian rhythm was formed around 25 weeks after birth. However, it was suggested that more Active sleep and delay of the circadian rhythm formation compare to infants after the same life.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、早産児の生後早期の入院中から1歳までの継続した睡眠覚醒の発達を示した。早産児の１年間のフォローアップという点では、対象数が少数ではあったが貴重であり、学術的意義は大きいと考える。また、ビデオ録画という客観的データを用いて、睡眠発達を示すことができた点では本邦初であり、サーカディアンリズムの形成時期などを分析し、今後のディベロップメンタルケアにつながる視点を得られた点では意義がある。
