DESCRIPTION (provided by applicant): Numerous US and international agencies have identified environmental and policy interventions as the most promising strategies for improving physical activity (PA), eating, and obesity. The evidence base on environmental and policy factors is deficient in 3 important ways this proposal will address. First, although the association between built environments and PA is widely accepted by authoritative groups like the CDC's Community Guide, accurate estimates of the strength of associations are not available because virtually all studies have limited environmental variability. If underestimated associations make it less likely decision makers pursue built environment changes, then public health suffers. Second, several studies document associations between the built environment and weight outcomes, but confirmatory studies are needed, especially those conducted in diverse environments. Third, measures are insufficiently detailed to give guidance about specific attributes of the built environment most likely to be effective interventions. To accurately assess the strength of association of the built environment with PA and weight status, greater environmental variability is required than any one country can provide. Thus, we propose a collaborative international study that uses a common design and measurement protocol to produce more accurate effect size estimates. Because US-only studies are expected to underestimate effect size, this international study will provide additional information to US decision makers. The International Physical activity and the Environment Network (IPEN) is led by investigators in the US, Australia and Belgium who have demonstrated common methods can be employed across countries. IPEN builds on completed studies in the US and Australia. Six countries were selected to collect new data based on the strength of investigators, preliminary studies, and in some cases, existing partial funding. For primary aims PA will be assessed by the validated long IPAQ survey, and built environment will be assessed by a validated built environment survey in all countries (approx N=9981). Analyses will examine how specific environmental attributes are related to PA domains, leisure and transport. Most countries also will have objective measures: accelerometry for PA; Geographic Information System data for environmental attributes. Thus, subsets of countries will be used to achieve secondary aims (range of N's from 5552 to 8781). All countries will select neighborhoods that vary on walkability and recruit a minimum of 500 adults aged 20-65. Data will be entered via the web to a central server, and adherence to all protocols and data quality will be monitored. Analyses will account for multi-level data. Team members are experienced in all aspects and have conducted 3 international PA studies that show the feasibility of IPEN. PUBLIC HEALTH RELEVANCE: Design of communities and access to recreation facilities are related to physical activity for transportation and leisure purposes as well as weight and risk of obesity. Because there is a limited range of activity-supportive environments in the US, studies conducted only in the US can underestimate impacts of the built environment. This study proposes to use comparable methods in at least 8 diverse countries to obtain accurate estimates of how strongly built environments are related to physical activity and weight, so policymakers have correct information to base decisions on.

描述（由申请人提供）：许多美国和国际机构都将环境和政策干预确定为改善体育活动（PA），饮食和肥胖的最有希望的策略。关于环境和政策因素的证据基础是该提案将解决的3种重要方式缺乏。首先，尽管建筑环境与PA之间的关联被诸如CDC社区指南之类的权威群体广泛接受，但由于几乎所有研究的环境变异性实际上都有限，因此无法获得对关联强度的准确估计。如果被低估的关联使决策者追求建筑环境变化的可能性较小，那么公共卫生就会受到影响。其次，几项研究记录了建筑环境和体重成果之间的关联，但需要验证性研究，尤其是在各种环境中进行的研究。第三，对措施的详细措施不足以提供有关最有效干预措施的建筑环境的特定属性的指导。为了准确评估建筑环境与PA和体重状况的关联强度，比任何一个国家所能提供的需要更大的环境变异性。因此，我们提出了一项协作国际研究，该研究使用共同的设计和测量方案来产生更准确的效果大小估计。由于预计仅使用美国的研究将低估效应规模，因此这项国际研究将为美国决策者提供其他信息。国际体育锻炼和环境网络（IPEN）由美国，澳大利亚和比利时的调查人员领导，这些调查员可以在各个国家使用共同的方法。 iPen建立在美国和澳大利亚完成的研究的基础上。选择了六个国家根据研究人员的实力，初步研究以及在某些情况下的现有部分资金来收集新数据。对于主要目标，PA将通过经过验证的长IPAQ调查进行评估，并将通过在所有国家 /地区进行经过验证的建筑环境调查来评估（n = 9981）。分析将研究特定的环境属性与PA域，休闲和运输的关系。大多数国家还将采取客观措施：PA的加速度计；环境属性的地理信息系统数据。因此，国家集将用于实现次要目标（N的范围从5552到8781）。所有国家都将选择随着步行性而变化的社区，并至少招募500名20-65岁的成年人。数据将通过Web输入到中央服务器，并遵守所有协议和数据质量。分析将考虑多层次数据。团队成员在各个方面都有经验，并进行了3项国际PA研究，以表明IPEN的可行性。公共卫生相关性：社区的设计和娱乐设施的访问与用于运输和休闲目的以及体重和肥胖风险的体育锻炼有关。由于在美国的活动支持环境有限，因此只有在美国进行的研究才能低估建筑环境的影响。这项研究建议在至少8个不同的国家使用可比较的方法，以获取与体育锻炼和体重相关的强大环境如何相关的准确估计，因此政策制定者拥有正确的信息来基本决策。
