DESCRIPTION (provided by applicant): Physical activity lowers the risk of obesity in children, is independently associated with numerous benefits related to health and well-being, and tracks from preschool-age to adolescence. The amount of time preschoolers spend outdoors is thought to correlate with their physical activity levels. Yet, most US children today likely spend less time playing outdoors than previous generations. The study of children's outdoor play time is not merely about resurrecting less digital, more unstructured childhoods, but is related to serious public health issues. Encouraging active outdoor play may prove to be an important method of enhancing children's overall development and health. Since the majority of US preschool-age children spend considerable time in child care programs, examining and pursuing strategies to increase outdoor physical activity in these settings is critical. Through child care settings, we may be able to change behaviors in large groups of children and particularly benefit more vulnerable children who have fewer opportunities for outdoor play and physical activity at home. Studying how physical activity and outdoor play enhance learning and development may provide additional incentives for early childhood professionals, parents and policy makers to promote these activities. An understanding of the accurate relationship between outdoor time and various outcomes is currently hampered by poor measurement. Robust measurement of outdoor time and an understanding of the context within which children are more active would inform further research and intervention. The overall research goal of this proposal is to characterize outdoor physical activity for preschoolers at child care and to understand environmental and social determinants of outdoor physical activity in order to inform intervention development. Specifically, Aim 1 is to validate light sensors and GPS units against direct observation as accurate measures of outdoor time. Aim 2 is to accurately quantify preschoolers' outdoor time at child care and its relationship to accelerometer-measured physical activity and various modifiable child care environment characteristics. Aim 3 focuses on developing and piloting an intervention in child care programs to increase the quality and quantity of outdoor time and studying the resulting impact on physical activity, health and development outcomes. This research plan is part of a K23 proposal designed to provide the scholarly training, mentorship and support necessary for Dr. Tandon to gain skills and experience needed to conduct research on children's outdoor physical activity to then develop and translate effective interventions into practices, programs and policies. Dr. Tandon is a pediatrician whose career goal is to become an independent investigator with a focus on promoting physical activity in children to address the critical health problems associated with sedentary, indoor lifestyles. To achieve this objective, she will pursue training in: 1) the measurement of physical activity and outdoor time, 2) the relationship of the built environment to physical activity, 3) incorporating cognitive outcomes into physical activity research and 4) developing and testing community-based interventions. .

描述(申请人提供)：体力活动降低儿童肥胖的风险，与许多与健康和幸福有关的好处独立相关，并跟踪从学龄前到青春期。学龄前儿童在户外活动的时间被认为与他们的身体活动水平有关。然而，与前几代人相比，今天的大多数美国儿童在户外玩耍的时间可能更少。对儿童户外游戏时间的研究不仅仅是为了让不那么数字化、更没有条理的童年复活，而且还与严重的公共卫生问题有关。鼓励积极的户外游戏可能被证明是促进儿童全面发展和健康的重要方法。由于大多数美国学龄前儿童在托儿计划中花费了相当多的时间，因此研究和实施在这些环境中增加户外体育活动的策略是至关重要的。通过儿童保育环境，我们可能能够改变大量儿童的行为，特别是使更脆弱的儿童受益，他们在家中没有太多机会进行户外游戏和体育活动。研究体育活动和户外游戏如何促进学习和发展，可能会为幼儿专业人员、家长和政策制定者提供额外的激励，以促进这些活动。目前，对户外时间和各种结果之间的准确关系的理解受到测量不力的阻碍。对户外时间的有力测量和对儿童在其中更活跃的背景的理解将为进一步的研究和干预提供依据。这项建议的总体研究目标是描述托儿所学龄前儿童户外体育活动的特征，并了解户外体育活动的环境和社会决定因素，以便为干预发展提供信息。具体地说，目标1是针对直接观测验证光传感器和GPS设备作为户外时间的准确测量。目标2是准确量化学龄前儿童在托儿时的户外时间及其与加速计测量的体力活动和各种可改变的托儿环境特征的关系。目标3侧重于在儿童保育项目中开发和试点干预措施，以增加户外时间的质量和数量，并研究由此对身体活动、健康和发展结果的影响。这项研究计划是K23计划的一部分，该计划旨在为Tandon博士提供必要的学术培训、指导和支持，以获得开展儿童户外体育活动研究所需的技能和经验，然后制定有效的干预措施，并将其转化为实践、计划和政策。坦登博士是一名儿科医生，他的职业目标是成为一名独立的调查员，专注于促进儿童的身体活动，以解决与久坐不动的室内生活方式相关的关键健康问题。为了实现这一目标，她将在以下方面进行培训：1)体力活动和户外时间的测量，2)建筑环境与体力活动的关系，3)将认知结果纳入体力活动研究，4)开发和测试基于社区的干预措施。。
