To describe the normative course of maternal sleep during the first 4 months postpartum.
Sleep was objectively measured using continuous wrist actigraphy. This was a longitudinal, field-based assessment of nocturnal sleep during postpartum weeks 2 through 16. Fifty mothers participated during postpartum weeks 2 through 13; 24 participated during postpartum weeks 9 through 16.
Maternal nocturnal sleep time was 7.2 (SD ± 0.95) hours and did not change significantly across postpartum weeks 2 through 16. Maternal sleep efficiency did improve across weeks 2 (79.7%; SD ± 5.5) through 16 (90.2%; SD ± 3.5) as a function of decreased sleep fragmentation across weeks 2 (21.7; SD ± 5.2) through 16 (12.8; SD ± 3.3).
Though postpartum mothers' total sleep time was higher than expected during the initial postpartum months, this sleep was highly fragmented (similar to fragmenting sleep disorders) and inefficient. This profile of disturbed sleep should be considered in intervention designs and family leave policies.
描述产后头 4 个月产妇睡眠的正常进程。
使用连续腕动描记法客观测量睡眠。这是对产后第 2 周到第 16 周夜间睡眠进行的一项纵向、基于现场的评估。共有 50 名产妇在产后第 2 周到第 13 周参与；24 名产妇在产后第 9 周到第 16 周参与。
产妇夜间睡眠时间为 7.2（SD±0.95）小时，产后第 2 周到第 16 周无明显变化。随着睡眠碎片化程度在第 2 周到第 16 周（21.7；SD±5.2）逐渐降低（21.7；SD±5.2），产妇睡眠效率逐渐提高（79.7%；SD±5.5）至第 16 周（90.2%；SD±3.5）。
尽管产后母亲在最初几个月的总睡眠时间高于预期，但这段睡眠高度碎片化（类似于睡眠障碍的碎片化）且效率低下。这种睡眠紊乱的模式应在干预设计和家庭休假政策中加以考虑。
