DESCRIPTION (provided by applicant): The proposed project will conduct a controlled evaluation of the impact of changes in the food and physical activity (PA) environments on childhood obesity and related behaviors in five New Jersey cities. These cities have been targeted for interventions by three major initiatives, affording the opportunity to conduct a natural experiment. The study aims are to advance our understanding of the relationship between elements of the environment and childhood obesity and related behaviors, assess the impact of specific environmental interventions, and demonstrate an innovative methodology for controlled evaluation of community interventions. Three research questions and implicit hypotheses will be tested: 1) What is the relative impact of children's exposure to changes in the community food environment, the school food environment, the community PA environment, and the school PA environment on changes in eating and PA behaviors? 2) What is the relative impact of children's exposure to changes in the community food environment, the school food environment, the community PA environment, and the school PA environment on changes in children's weight status? 3) What roles do perceptions of the environment and barriers to access play in these relationships? The research design relies upon a prospective, longitudinal study of a randomly selected panel of 1200 children in these cities. The research team collected comprehensive baseline data on obesity-related behaviors and body mass index in 2009-2010. The data also include documentation of the food and physical activity environments to which these children were exposed (geo-coded for analysis). Comprehensive data collection on children will be repeated in four years and relevant changes in the environment will be monitored over the same period. Changes may include presence of new opportunities for healthy eating or physical activity (e.g., new supermarkets, playgrounds); significant enhancement of existing ones (e.g., addition of healthy foods to convenience stores, expanded physical education in schools), as well as non-intervention related change (e.g., retail outlets that close). Individual-level exposure will be measured by proximity of the environmental change to each child's residence (using geo-spatial methods). The analysis will evaluate the impact of exposure to these changes on a comprehensive set of outcomes including behaviors relevant to food consumption and PA as well as weight status. The research design facilitates an exceptional degree of control in isolating the effects of particular intervention strategies. The project's impact on policy will be amplified by the researchers' extensive relationships with stakeholders in the studied cities, ongoing efforts to disseminate findings from the recently conducted cross-sectional study, and the Rutgers Center for State Health Policy's history of informing state-level policy in NJ and around the nation.

描述（由申请人提供）：拟议的项目将对五个新泽西城市的儿童肥胖和相关行为的变化（PA）环境的变化（PA）进行受控评估。这些城市已被三项主要举措针对干预措施，提供了进行自然实验的机会。该研究的目的是促进我们对环境要素与儿童肥胖与相关行为之间的关系的理解，评估特定环境干预的影响，并展示一种创新的方法，用于控制社区干预措施的评估。将测试三个研究问题和隐性假设：1）儿童接触社区食物环境变化，学校食品环境，社区PA环境以及学校PA环境对饮食和PA行为变化的相对影响是什么？ 2）儿童接触社区食物环境，学校食品环境，社区PA环境和PA环境的相对影响对儿童体重状况的变化有什么影响？ 3）对环境的看法以及在这些关系中访问游戏的障碍的角色？ 研究设计依赖于这些城市中1200名儿童随机选择的前瞻性，纵向研究。研究小组在2009 - 2010年收集了有关肥胖相关行为和体重指数的全面基线数据。数据还包括对这些孩子暴露的食物和体育活动环境的文献（进行分析的地理编码）。关于儿童的全面数据收集将在四年内重复，并且将在同一时期监视环境的相关变化。变化可能包括存在健康饮食或体育锻炼的新机会（例如，新的超市，游乐场）；现有的食品（例如，在便利店增加健康食品，在学校中扩大的体育教育扩大）以及与非干预相关的变化（例如，关闭的零售商店）的显着增强。个人水平的暴露将通过接近每个孩子住所的环境变化（使用地理空间方法）来衡量。该分析将评估暴露于这些变化对一组全面结果的影响，包括与食物消耗和PA和体重状况有关的行为。研究设计促进了隔离特定干预策略的影响的特殊控制程度。该项目对政策的影响将被研究人员与研究城市中的利益相关者的广泛关系，持续的努力，从最近进行的横断面研究中传播发现，以及罗格斯州卫生政策中心的历史，该中心的历史是为NJ和全国各地的国家级政策提供信息。
