title: Comparisons of sleep patterns between mothers in post-partum from 9 to 12 weeks and non-pregnant women.
abstract: In order to evaluate two patterns of interrupted and non-interrupted sleep for the post-partum mothers from 9 to 12 weeks after delivery, we compared them with sleep patterns of non-pregnant women. Subjects were 10 primipara and 12 non-pregnant women. Their polysomnographic recordings were made using a Medilog recorder at home. In interrupted sleep, low sleep efficiency, decreased total sleep time, and a decreased percentage of stage 2 were significantly observed compared with non-pregnant women. Sleep parameters of non-interrupted sleep, except for increased percentage of stage 4, did not show any significant differences from non-pregnant women. Mothers' sleep fluctuated between interrupted sleep similar to the early post-partum sleep from 1 to 6 weeks and non-interrupted sleep with increased stage 4.
