To examine longitudinally differences in (1) objective and subjective sleep patterns and (2) parenting functioning (i.e. maternal emotional distress, maternal separation anxiety, and parental involvement in infant care) between room-sharing and solitary-sleeping mother-infant dyads.
Maternal and infant sleep, sleeping arrangements, and parental functioning were assessed at 3 (N = 146), 6 (N = 141), 12 (N = 135), and 18 (N = 130) months postpartum. Maternal and infant sleep were assessed with actigraphy and sleep diaries for five nights. Questionnaires were used to assess sleeping arrangements, nighttime breastfeeding, and parental functioning.
Persistent room-sharing mothers (i.e. sharing a room with the infant on at least three assessment points) had significantly lower actigraphy-based sleep percent, lower longest sleep periods, and more night-wakings than persistent solitary-sleeping mothers. For infants, differences in actigraphic sleep were found only in longest sleep period, although mothers of persistent room-sharing infants reported more infant night-wakings than mothers of persistent solitary-sleeping infants. The trajectories of maternal and infant sleep in both room-sharing and solitary-sleeping groups demonstrated that sleep became more consolidated with time. Group differences indicated higher maternal separation anxiety and lower paternal overall and nighttime involvement in infant caregiving in room-sharing families compared with solitary-sleeping families.
The findings are discussed in light of the latest American Academy of Pediatrics recommendation to share a room until 12 months postpartum. Although no causal effects can be inferred from this study, maternal sleep quality and certain parenting characteristics seem to be important factors to consider when parents consult about sleeping arrangements.
纵向考察同室睡眠和单独睡眠的母婴二元组在以下两方面的差异：（1）客观和主观睡眠模式；（2）养育功能（即母亲的情绪困扰、母亲的分离焦虑以及父母对婴儿护理的参与度）。
在产后3个月（N = 146）、6个月（N = 141）、12个月（N = 135）和18个月（N = 130）时评估母婴睡眠、睡眠安排和养育功能。使用活动记录仪和睡眠日记对母婴睡眠进行连续五晚的评估。通过问卷调查评估睡眠安排、夜间母乳喂养和养育功能。
持续同室睡眠的母亲（即在至少三个评估点与婴儿同室睡眠）基于活动记录仪记录的睡眠百分比显著更低，最长睡眠时间更短，夜间醒来次数更多，相比持续单独睡眠的母亲。对于婴儿，仅在最长睡眠时间上发现了活动记录仪记录的睡眠差异，尽管持续同室睡眠婴儿的母亲报告的婴儿夜间醒来次数比持续单独睡眠婴儿的母亲更多。同室睡眠和单独睡眠两组中母婴睡眠轨迹均表明，睡眠随时间推移变得更加稳定。组间差异表明，与单独睡眠家庭相比，同室睡眠家庭中母亲的分离焦虑更高，父亲在婴儿护理中的总体参与度和夜间参与度更低。
根据美国儿科学会最新建议，即产后12个月内母婴应同室睡眠，对研究结果进行了讨论。尽管本研究无法推断因果关系，但当父母咨询睡眠安排时，母亲的睡眠质量和某些养育特征似乎是需要考虑的重要因素。
