title: Longitudinal study for sleep-wake behaviours of mothers from pre-partum to post-partum using actigraph and sleep logs.
abstract: To understand the sleep-wake behaviours from the fifth pre-partum week to the 15th post-partum week by the number of actigraphic activities and sleep logs were evaluated in 10 women. It was found that total sleep time shortened, sleep efficiency decreased, and wake after sleep onset (WASO) increased in the weeks immediately after delivery. Compared with late pregnancy, total sleep time and sleep efficiency deteriorated significantly from the delivery week to the 12th post-partum week and there was a longer period of WASO until the 11th postpartum week. The after-delivery sleep parameters estimated by the actigraph were worse than those estimated from sleep logs.
