Outline of Final Research Achievements

Based on references and precedent studies, we examined constitution to clarify [actual situation of sleep time] and [quality of sleep] after giving birth. And we developed the sleep diary (EMSD). The subjects' total sleep time of the day were investigated through their smart phones from 5 days after giving birth. Comparison between the pregnancy period and all periods after giving birth revealed significant difference (all p<.001). Significant positive correlations were seen between total sleep time and feeling of sound sleep until 5 days after giving birth when the subjects were hospitalized. The other side, significant negative correlations were seen between total sleep time and feeling of sound sleep from the day after having left the hospital to one month after giving birth.
The sleep time and feeling of sound sleep by practical support after discharge are required.

Academic Significance and Societal Importance of the Research Achievements

高齢初産婦の睡眠は主睡眠時間と総睡眠時間は正の相関がある事が判明した。さらに、入院中は睡眠時間が短くても熟睡感を得ており、その反面、退院後は熟睡できずに、眠ろうとして睡眠時間を長くとっている事も窺えた。
また、睡眠を阻害する要因が多くあり、母乳育児に起因する者が最も多く、次いで初めての育児に起因した要因、心身の体調に起因した要因、環境要因がある事が判明した。しかし、睡眠が獲得できている者からの睡眠促進要因も判明した。こういった因子も踏まえて睡眠を評価できるような測定ツール開発の必要性も窺えた。
