项目摘要

PROJECT SUMMARY Almost half of American adults have a preventable chronic disease, most of which could be improved with regular physical activity (PA). These proportions are even higher for racially/ethnically diverse populations where disparities emerge in both chronic disease and PA behavior. Importantly, adults with ~20 minutes/day of physical activity have a 33% lower risk for all-cause mortality than those who are inactive We know that physical activity patterns for adults have their developmental beginnings in childhood. Although we know roughly when, specifically how to affect these patterns is multi-factorial. Direct “cause and effect” models are insufficient to accommodate the layers of complexity involved in pattern formation. Such complexity includes multiple dynamic systems with inter- and intra- interactions that influence children’s PA behaviors, including the built environment, the social environment (both inside and outside the home), and cognitive processes that vary during- child development. Providing a deeper understanding of these dynamics can advance interventions and policies for childhood PA behaviors and long-term health disparities reduction. To accomplish this task, we will leverage approaches more commonly used outside of biomedical research, in fields such as ecology and social science, and bring together a trans-disciplinary and cross-sector team of experts in complex systems modeling approaches (Brookings Institution) and pediatric PA and health disparities (Vanderbilt) to build an etiologic Agent-Based Model (ABM) that identifies which modifiable determinants may have the biggest impact on PA pattern formation for diverse young children. This project will utilize an independent dataset collected by the Growing Right Onto Wellness (GROW) Trial of child-parent pairs to inform the ABM. All of these families represented diverse under-served populations in Tennessee. The GROW Trial (total N=610 children ages 3-8) collected detailed objective PA data (via accelerometry) at four annual time- points over the study period (for child-parent pairs), as well as data on the child’s social environment, built environment, and cognitive processes. Using ABM in this context leverages the diversity and richness of this longitudinal dataset to build a model with empirically derived parameter estimates to generate new insights into supporting early childhood PA in diverse populations. ABMs allows us to examine how, when, and for whom PA behaviors are dynamically shaped by macro-level influences such as the built environment in which children reside, meso-level influences such as social environments both in and out of the home, and micro-level influences such as individual cognitive processes in early childhood development. We will examine the potential heterogeneity in these influences across child characteristics including gender, race/ethnicity, BMI, and BMI change over time. The result of this project will be a set of data-driven policy recommendations, based on a complex systems approach to studying childhood PA behaviors, that can be applied in real-world community settings.
项目摘要 几乎一半的美国成年人患有可预防的慢性疾病,其中大多数可以改善 定期体育锻炼(PA)。对于大致/种族多样的人群,这些比例甚至更高 慢性疾病和PA行为中出现分布的地方。重要的是,大约20分钟/天的成年人 与不活动的人相比,身体活动的全因死亡率低33%,我们知道 成年人的体育锻炼模式在童年时期就开始发展。虽然我们知道 大致是在特殊影响这些模式的时候是多因素的。直接的“因果关系”模型是 不足以适应模式形成所涉及的复杂性层。这种复杂性包括 具有影响儿童PA行为的多个动态系统,包括 建筑环境,社会环境(内部和外部)以及不同的认知过程 在儿童发展期间。提供对这些动态的更深入的了解可以推进干预措施,并且 儿童PA行为的政策和长期健康分配减少。 为了完成这项任务,我们将利用更常用的生物医学之外使用的方法 研究,在生态和社会科学等领域,并将跨学科和跨部门汇集在一起 复杂系统建模方法(Brookings Institution)和PA和Health的专家团队 差异(范德比尔特)建立一个基于病因的模型(ABM),该模型识别哪些可修改 确定对潜水孩子的PA模式形成可能会产生最大的影响。这个项目将 利用由生长右生长到儿童对的健康(成长)试验中收集的独立数据集 通知ABM。所有这些家庭代表了田纳西州的潜水员人口不足。成长 试验(总n = 3-8岁的610名儿童)在四个年度时收集了详细的客观PA数据(通过加速度计) 在研究期间的积分(对于儿童对)以及有关儿童社会环境的数据 环境和认知过程。在这种情况下使用ABM利用了这种情况的多样性和丰富性 纵向数据集以构建具有经验得出的参数估算的模型,以生成新的见解 支持潜水员人群的幼儿PA。 ABM允许我们检查如何,何时以及为谁 PA行为是由宏观影响动态影响的,例如建筑环境 儿童居住,在家中和外面的社交环境等中期影响以及微观级别的影响 影响诸如幼儿发展中个人认知过程之类的影响。我们将研究潜力 这些影响的异质性在儿童特征跨性别,种族/种族,BMI和BMI等影响 随着时间的变化。该项目的结果将是一组基于数据驱动的策略建议 关于研究儿童PA行为的复杂系统方法,可以应用于现实世界中 社区设置。
