DESCRIPTION (provided by applicant): Childhood obesity has become a major public health concern. One of the key gaps in understanding childhood obesity is the lack of an accurate assessment of the intensity of children's physical activities in their social context. Although extensive work along these lines has been conducted for adults, little has been conducted for children. In large-scale surveys, social and behavioral scientists collect information on children's participation in socially meaningful categories. But these measures do not capture the intensity of physical activity involved. Exercise physiologists and obesity researchers have developed self-report measures of the type, duration, and intensity of children's physical activity; however, they do not collect information on the social context. The specific aim of this proposed project is to convene a network of scientists conducting research from multiple perspectives, that of social and behavioral science, exercise physiology, and public health and nutrition, to study children's activities. This network would focus upon children of ages not typically studied, those 3-5, as well as those 6-12, and would consider children of diverse ethnic backgrounds. The objectives address the four areas of research design, measurement, data collection techniques, and analytic methods. Our specific aims are: 1) To evaluate the current state of measurement and data collection on physical activity and associated societally meaningful categories of activity, 2) To evaluate how to link the social and behavioral scientific approaches to physical activity and the physiological approaches to determining activity levels and energy expenditures, and 3) To conduct pilot testing to explore how to incorporate such techniques and to determine the cost and effectiveness of recommended methods/equipment for large-scale studies.

描述（由申请人提供）： 儿童肥胖已成为一个主要的公共卫生问题。了解儿童肥胖的主要差距之一是缺乏对儿童在社会背景下身体活动强度的准确评估。尽管针对成人开展了大量此类工作，但针对儿童开展的工作却很少。在大规模调查中，社会和行为科学家收集有关儿童参与具有社会意义的类别的信息。但这些措施并没有反映所涉及的体力活动的强度。运动生理学家和肥胖研究人员已经制定了儿童体力活动类型、持续时间和强度的自我报告测量方法；然而，他们不收集有关社会背景的信息。该拟议项目的具体目标是召集一个科学家网络，从社会和行为科学、运动生理学以及公共卫生和营养学等多个角度进行研究，以研究儿童的活动。该网络将重点关注通常不被研究的年龄的儿童，即 3-5 岁以及 6-12 岁的儿童，并将考虑不同种族背景的儿童。这些目标涉及研究设计、测量、数据收集技术和分析方法四个领域。我们的具体目标是：1）评估身体活动和相关的具有社会意义的活动类别的测量和数据收集的当前状态，2）评估如何将社会和行为科学方法与身体活动以及确定身体活动的生理方法联系起来活动水平和能量消耗，以及 3) 进行试点测试，探索如何整合此类技术，并确定大规模研究推荐方法/设备的成本和有效性。
