目的:基于进化的睡眠研究对于确定母亲和婴儿的母乳喂养和夜间睡眠接近度的相互依赖至关重要。关于共同睡眠的进化观点也经常强调睡眠接近的情感动机和潜在好处,包括父母与婴儿的结合。然而,对于母亲和父亲来说,婴儿睡眠位置和联系之间的这种潜在联系仍然没有得到充分研究。此外,在欧美背景下,同床与家庭压力和困难的儿童气质有关,主要是通过产妇报告。我们对父系心理社会动力学是否因家庭睡眠安排而有所不同知之甚少,尽管父亲和其他亲属经常出现在跨文化的共眠环境中。这里,我们的目标是帮助解决一些有关父亲和家庭睡眠安排的知识差距。
方法:利用美国中西部父亲的样本(N=195),我们收集了社会人口统计学和调查数据来分析婴儿夜间睡眠位置之间的联系,父系的社会心理健康,父子关系,和婴儿气质。从父亲的报告,家庭通常被描述为孤独的睡眠,共享床上用品,或共享房间(不共享床铺)。
结果:我们发现,经常合房或同床的父亲,分别,据报道,结合力比孤独的睡眠者强。同床共枕的父亲还报告说,他们的婴儿有更多的负面气质,并且由于与孩子的困难,他们也倾向于报告更大的育儿压力。
结论:这些横断面结果有助于突出具有深层系统发育和进化史的实践,比如同睡,可以在社区内可变地表达,具有家庭依赖的利益或菌株的潜力。
OBJECTIVE: Evolutionary-grounded sleep research has been critical to establishing the mutual dependence of breastfeeding and nighttime sleep proximity for mothers and infants. Evolutionary perspectives on cosleeping also often emphasize the emotional motivations for and potential benefits of sleep proximity, including for parent-infant bonding. However, this potential link between infant sleep location and bonding remains understudied for both mothers and fathers. Moreover, in Euro-American contexts bedsharing has been linked to family stress and difficult child temperament, primarily via maternal
reports. We know relatively little about whether paternal psychosocial dynamics differ based on family sleep arrangements, despite fathers and other kin often being present in the cosleeping environment across cultures. Here, we aim to help address some of these gaps in knowledge pertaining to fathers and family sleep arrangements.
METHODS: Drawing on a sample of Midwestern U.S. fathers (N=195), we collected sociodemographic and survey data to analyze links between infant nighttime sleep location, paternal psychosocial well-being, father-infant bonding, and infant temperament. From fathers\'
reports, families were characterized as routinely solitary sleeping, bedsharing, or roomsharing (without bedsharing).
RESULTS: We found that routinely roomsharing or bedsharing fathers, respectively, reported stronger bonding than solitary sleepers. Bedsharing fathers also reported that their infants had more negative temperaments and also tended to report greater parenting-related stress due to difficulties with their children.
CONCLUSIONS: These cross-sectional results help to highlight how a practice with deep phylogenetic and evolutionary history, such as cosleeping, can be variably expressed within communities with the potential for family-dependent benefits or strains.
