项目摘要

PROJECT SUMMARY Although physical activity, sedentary behavior, and sleep (i.e., 24-hr behaviors) have been associated with cognitive and brain outcomes in older children and adults, studies are limited in early childhood and typically examine these behaviors separately. Given that early childhood serves as an important time for brain and cognitive development and when healthy habits (i.e., low sedentary time, high physical activity, and sufficient sleep) are formed, the goal of this research is to examine the relations between 24-hr behaviors, cognition, and brain structure (i.e., hippocampal volume, as this structure is a key brain region to learning and memory) in early childhood. The aims of this proposal are to determine if 24-hr behaviors are associated with 1) cognitive performance and 2) hippocampal volume in early childhood. Data from two ongoing studies examining the benefits of napping on memory in early childhood (i.e., children ages 33 to 71 months) will be used: a clinical trial (NIH R01 HL111695) with one measurement period and a longitudinal clinical trial (NIH R21 HD094758/NSF 1749280) with three measurement periods over one year. To address the aims of this project, cross-sectional and longitudinal analyses from various subgroups of participants of the two studies will be conducted. Measurements will include time spent in each of the 24-hr behaviors from 16-days of actigraphy (i.e., accelerometry via a wrist monitor), cognitive performance from multiple assessments, and hippocampal volume from magnetic resonance imaging. The aims of this proposal have public health significance in that they will identify potential windows of opportunity to intervene on health behaviors, learning, and cognitive function at a critical developmental period of the lifespan. The findings can inform future intervention studies, family practices, early childhood education policies, and comprehensive guidelines for a 24-hr cycle. Collectively, the proposed development plan incorporates activities for training in developmental science, sleep, neurocognitive measurement, statistical analyses, and scientific writing. Successful completion of this proposed training plan will result in several submissions of first-author manuscripts to peer-reviewed journals and an essential research foundation to support a competitive early career funding proposal. The fellowship will provide protected time and unique cross-disciplinary mentorship for successful completion of research and training goals.

项目概要尽管体力活动、久坐行为和睡眠（即 24 小时行为）与对于年龄较大的儿童和成人的认知和大脑结果，研究仅限于幼儿期，并且通常分别检查这些行为。鉴于幼儿期是大脑和大脑发育的重要时期认知发展和健康习惯（即久坐时间少、体力活动多、充足的身体活动）睡眠）形成后，本研究的目标是检查 24 小时行为、认知和睡眠之间的关系。早期的大脑结构（即海马体积，因为该结构是学习和记忆的关键大脑区域）童年。该提案的目的是确定 24 小时行为是否与 1) 认知相关表现和2）幼儿时期的海马体积。来自两项正在进行的研究的数据幼儿期（即 33 至 71 个月的儿童）小睡对记忆力的好处将被利用：一项临床研究试验（NIH R01 HL111695），具有一个测量周期和一项纵向临床试验（NIH R21 HD094758/NSF 1749280），一年内有三个测量周期。为了实现该项目的目标，跨部门将对这两项研究的参与者的各个亚组进行纵向分析。测量将包括 16 天体动记录中每个 24 小时行为所花费的时间（即通过手腕监视器进行的加速度测量）、多次评估的认知表现以及海马体积来自磁共振成像。该提案的目标具有公共卫生意义，因为它们将确定干预健康行为、学习和认知功能的潜在机会之窗生命发育的关键时期。研究结果可以为未来的干预研究、家庭实践、幼儿教育政策以及 24 小时周期的综合指导方针。总的来说，拟议的发展计划包括发展科学、睡眠、神经认知方面的培训活动测量、统计分析和科学写作。顺利完成本拟议培训计划将导致向同行评审期刊提交多份第一作者手稿和一项重要研究基金会支持有竞争力的早期职业资助提案。该奖学金将提供受保护的时间和独特的跨学科指导，以成功完成研究和培训目标。
