Despite growing support among public health researchers and practitioners for environmental approaches to obesity prevention, there is a lack of empirical evidence from intervention studies showing a favorable impact of either increased healthy food availability on healthy eating or changes in the built environment on physical activity. It is therefore critical that we carefully evaluate initiatives targeting the community environment to expand the evidence base for environmental interventions. We describe the approaches used to measure the extent and impact of environmental change in 3 community-level obesity-prevention initiatives in California. We focus on measuring changes in the community environment and assessing the impact of those changes on residents most directly exposed to the interventions.
尽管公共卫生研究人员和从业者越来越支持采取环境措施预防肥胖，但干预研究中缺乏实证证据表明增加健康食品供应对健康饮食或改善建筑环境对身体活动有积极影响。因此，我们必须仔细评估针对社区环境的举措，以扩大环境干预措施的证据基础。我们描述了在加利福尼亚州的 3 个社区一级预防肥胖倡议中用于衡量环境变化程度和影响的方法。我们专注于衡量社区环境的变化，并评估这些变化对最直接接触干预措施的居民的影响。
