The project will use epidemiology, systematic review and qualitative methods to explore the associations between physical activity and pre-school environments to design an intervention to increase physical activity. This project will be unique in using the special resource of the MRC Epidemiology Unit's International Children's Accelerometry Database (ICAD) to investigate physical activity of pre-school children in 5 countries. I will collaborate with the Universities of Loughborough, Cambridge and those providing ICAD data. Further, I will use observation of the environment and practices of staff in 12 nurseries and accelerometer data for 116 children aged 2-4 from the NAP SACC UK RCT. The research questions and methods will be: 1. How does the time spent in sedentary, light and moderate vigorous physical activity (MVPA) differ by country, SES, gender, age, setting and time of day in pre-school children? Method: individual- participant meta-analysis of accelerometer data of ~900 children aged 2-4-year-old children in ICAD and the NAP SACC UK trial. 2. What factors are associated with the time spent in sedentary, light and MVPA among pre-school children in pre-school settings and at home? Method: systematic review and meta-analysis of observational studies on the predictors of physical activity in 2-4-year-olds. 3. What are the barriers and facilitators of changing factors associated with sedentary time and physical activity? How can these be facilitated or overcome? Methods: In-depth interviews with staff in 20 pre-school settings (parents, day nurseries, school nurseries, pre-schools and child minders). In-depth interviews with staff in 10 Local Authorities responsible for promoting physical activity. 4. What intervention design has the support of pre-school professionals and physical activity professionals for physical activity in pre-school settings? Method: Delphi development of intervention design.

该项目将利用流行病学、系统评价和定性方法来探索体育活动与学前环境之间的关联，以设计增加体育活动的干预措施。该项目的独特之处在于利用 MRC 流行病学部门的国际儿童加速度数据库 (ICAD) 的特殊资源来调查 5 个国家的学前儿童的身体活动。我将与拉夫堡大学、剑桥大学以及提供 ICAD 数据的大学合作。此外，我将使用对 12 个托儿所的环境和工作人员做法的观察以及来自 NAP SACC UK RCT 的 116 名 2-4 岁儿童的加速度计数据。研究问题和方法如下： 1. 学龄前儿童在久坐、轻度和中度剧烈体力活动 (MVPA) 上花费的时间如何因国家、社会经济地位、性别、年龄、环境和时间而异？方法：对 ICAD 和 NAP SACC UK 试验中约 900 名 2-4 岁儿童的加速度计数据进行个体参与者荟萃分析。 2. 学前儿童在学前机构和家里的久坐时间、光照时间和 MVPA 与哪些因素相关？方法：对 2-4 岁儿童身体活动预测因素的观察性研究进行系统回顾和荟萃分析。 3. 与久坐时间和体力活动相关的变化因素的障碍和促进因素是什么？如何促进或克服这些问题？方法：对 20 个学前机构（家长、日间托儿所、学校托儿所、学前班和托儿所）的工作人员进行深入访谈。对 10 个地方当局负责促进身体活动的工作人员进行了深入访谈。 4. 对于学前环境中的体育活动，哪些干预设计得到了学前专业人士和体育活动专业人士的支持？方法：Delphi开发干预设计。
