Sleep disruption has been suggested to contribute to postpartum mood, but few studies have explored differences in this relationship between nulliparous and multiparous mothers. This study compared the interaction of sleep and mood as a function of parity. Thirty-five nulliparous and 34 multiparous mothers completed questionnaires on mood and sleep, and wore actigraphs for 7 days during the third trimester of pregnancy and within 2 weeks postpartum. Mood and objective sleep were better in multiparas than in nulliparas after delivery. However, other than a stronger association between subjective sleep and stress in nulliparous mothers, the relationship between sleep and mood did not differ significantly between the two groups. This suggests that parity might play only a limited role in the interaction between sleep and mood during the immediate postpartum period.
睡眠中断被认为与产后情绪有关，但很少有研究探讨初产妇和经产妇之间这种关系的差异。本研究比较了睡眠和情绪相互作用与生育次数的关系。35 名初产妇和 34 名经产妇在妊娠晚期和产后 2 周内完成了情绪和睡眠问卷，并佩戴了活动记录仪 7 天。产后经产妇的情绪和客观睡眠比初产妇好。然而，除了初产妇主观睡眠与压力之间的关联更强之外，两组之间睡眠与情绪之间的关系并没有显著差异。这表明，在产后即刻期间，生育次数可能仅在睡眠和情绪之间的相互作用中起有限作用。
