PROJECT SUMMARY/ABSTRACT The transition to parenthood is a period of profound transformation and often vulnerability in new parents. Though most of the research on this transition has focused on mothers, new fathers must also adapt to parenthood. Many parents experience sleep deprivation and poor sleep quality, which may increase mental health risks of new parents and reduce the quality of caregiving behavior. Prior work in non-parent samples suggests that sleep quality may be linked to the structural connectivity of the brain, as measured within white matter microstructure (WMM). Less efficient connectivity of WMM has also been associated with mental health problems. This project will examine postpartum sleep quality in first-time fathers and test associations with their postpartum mental health and WMM. The project also examines postpartum WMM as a mediator between sleep quality and mental health symptoms during the transition to parenthood. This project draws from an existing longitudinal study of first-time parents followed from the prenatal to postpartum periods that incorporated neuroimaging. Study aims are to: (1) Examine how postpartum sleep quality, controlling for prenatal sleep quality, affects psychological adjustment to parenthood in new fathers; (2) Investigate whether sleep quality is associated with postpartum white matter microstructure (WMM) among first-time fathers; (3) Examine the mediating role of postpartum WMM on the relationship between postpartum sleep quality and fathers’ adjustment to parenthood. Study findings can provide insight into the role of sleep on the paternal brain and mental health and inform interventions facilitating the adjustment to parenthood. The proposed project will support the applicant’s training in biobehavioral research methods to become an interdisciplinary health and family studies researcher.

项目概要/摘要 为人父母的过渡是一个深刻转变的时期，并且在新的环境中往往很脆弱。 尽管大多数关于这一转变的研究都集中在母亲身上，但新父亲也必须适应。 许多父母都会经历睡眠不足和睡眠质量差的情况，这可能会增加精神压力。 新父母的健康风险，并降低非父母样本中先前的护理行为质量。 表明睡眠质量可能与大脑的结构连通性有关，正如在白种人中测量的那样 物质微观结构 (WMM) 的低效连接也与心理健康有关。 该项目将检查初为人父者的产后睡眠质量，并测试与他们的关系。 该项目还研究了产后 WMM 作为两者之间的中介因素。 该项目借鉴了为人父母期间的睡眠质量和心理健康症状。 现有的对初为父母的从产前到产后的纵向研究表明 合并神经影像学。 研究目的是：（1）检查产后睡眠质量，控制产前睡眠质量， (2)调查睡眠质量是否良好 与初次父亲的产后白质微结构（WMM）相关；（3）检查 产后WMM在产后睡眠质量与父亲关系中的中介作用 研究结果可以深入了解睡眠对父亲大脑的作用。 拟议的项目将促进心理健康和干预措施的调整。 支持申请人接受生物行为研究方法的培训，使其成为跨学科的健康和 家庭研究研究员。
