The purpose of this study was to examine how healthy weight status among youth was related to (i) three proximity-based park variables: number of parks within 1 km of home, total area of parkland within 1 km, and distance to the closest park from home, and (ii) the availability of 13 specific park facilities within 1 km of the home. Data were collected from parents of children living in four neighborhoods of a medium-sized Canadian city. Logistic regression analyses revealed that none of the three proximity-based park variables was significantly associated with healthy weight status among children in the sample. However, when availability of the 13 park facilities was examined, children with a park playground within 1 km were almost five times more likely to be classified as being of a healthy weight rather then at risk or overweight compared to those children without playgrounds in nearby parks. Results suggest that availability of certain park facilities may play a more important role in promoting physical activity and healthy weight status among children than availability of park space in general. Implications for park design are discussed.
（i）三个基于邻近度的公园变量，即家周围1公里内公园的数量、家周围1公里内公园绿地的总面积以及家到最近公园的距离；（ii）家周围1公里内13种特定公园设施的可及性。数据收集自加拿大一个中等规模城市四个社区中儿童的家长。逻辑回归分析表明，样本中儿童的健康体重状况与三个基于邻近度的公园变量均无显著关联。然而，在考察13种公园设施的可及性时，与附近公园没有游乐场的儿童相比，家周围1公里内有公园游乐场的儿童被归类为健康体重而非有风险或超重的可能性几乎高出四倍。结果表明，某些公园设施的可及性在促进儿童身体活动和健康体重状况方面可能比公园空间的可及性发挥更重要的作用。文中还讨论了对公园设计的启示。
