背景资料：增加体育活动的国家和国际战略强调可产生广泛和持久影响的环境和政策变化。需要多个国家使用可比方法提供证据，以加强此类举措的证据基础。由于某些环境和政策变化可能产生普遍的影响，而另一些则可能取决于每个国家的具体情况，因此，只有采用可比方法进行国际研究，才能确定相关的差异。方法：目前有12个国家参加了国际体育活动与环境网络（IPEN）研究。国际消除持久性有机污染物网络的成人研究设计涉及从环境步行属性和社会经济地位差异很大的社区招募成年参与者。结果：12个国家中有11个提供了加速计数据，11个提供了地理信息系统数据。目前的预测表明，14 119名参与者将提供关于建筑环境和身体活动的调查数据，7 145名参与者可能提供关于自变量和因变量的客观数据。虽然研究具有高度可比性，但需要根据当地情况进行一些调整。结论：这项研究旨在为循证的国际和具体国家的身体活动政策和干预措施提供信息，以帮助预防发达国家高发、发展中国家迅速增长的肥胖症和其他慢性病。
Background: National and international strategies to increase physical activity emphasize environmental and policy changes that can have widespread and long-lasting impact. Evidence from multiple countries using comparable methods is required to strengthen the evidence base for such initiatives. Because some environment and policy changes could have generalizable effects and others may depend on each country's context, only international studies using comparable methods can identify the relevant differences. Methods: Currently 12 countries are participating in the International Physical Activity and the Environment Network (IPEN) study. The IPEN Adult study design involves recruiting adult participants from neighborhoods with wide variations in environmental walkability attributes and socioeconomic status (SES). Results: Eleven of twelve countries are providing accelerometer data and 11 are providing GIS data. Current projections indicate that 14,119 participants will provide survey data on built environments and physical activity and 7145 are likely to provide objective data on both the independent and dependent variables. Though studies are highly comparable, some adaptations are required based on the local context. Conclusions: This study was designed to inform evidencebased international and country-specific physical activity policies and interventions to help prevent obesity and other chronic diseases that are high in developed countries and growing rapidly in developing countries.
