Conflicting findings on associations between food and physical activity (PA) environments and children's weight status demand attention in order to inform effective interventions. We assess relationships between the food and PA environments in inner-city neighborhoods and children's weight status and address sources of conflicting results of prior research.
Weight status of children ages 3-18 was assessed using parent-measured heights and weights. Data were collected from 702 children living in four low-income cities in New Jersey between 2009 and 2010. Proximity of a child's residence to a variety of food and PA outlets was measured in multiple ways using geo-coded data. Multivariate analyses assessed the association between measures of proximity and weight status.
Significant associations were observed between children's weight status and proximity to convenience stores in the 1/4 mile radius (OR = 1.9) and with presence of a large park in the 1/2 mile radius (OR = 0.41). No associations were observed for other types of food and PA outlets.
Specific aspects of the food and PA environments are predictors of overweight and obese status among children, but the relationships and their detection are dependent upon aspects of the geospatial landscape of each community.
为了提供有效的干预措施，需要关注有关食品和身体活动（PA）环境与儿童体重状况之间关联的相互矛盾的发现。我们评估了内城社区的食品和 PA 环境与儿童体重状况之间的关系，并解决了先前研究结果相互矛盾的原因。
使用父母测量的身高和体重来评估 3-18 岁儿童的体重状况。2009 年至 2010 年期间，在新泽西州的四个低收入城市中收集了 702 名儿童的数据。使用地理编码数据以多种方式测量了儿童居住地与各种食品和 PA 场所的接近程度。多变量分析评估了接近度测量值与体重状况之间的关联。
观察到儿童体重状况与 1/4 英里半径内的便利店接近程度（OR = 1.9）和 1/2 英里半径内的大型公园存在（OR = 0.41）之间存在显著关联。其他类型的食品和 PA 场所没有关联。
食品和 PA 环境的特定方面是儿童超重和肥胖状况的预测因素，但这些关系及其检测取决于每个社区的地理空间景观的各个方面。
