这项研究的目的是通过一项纵向研究来评估公园和娱乐资源的邻近程度如何影响儿童肥胖的发展。1993年和1996年收集了来自南加州12个社区的3173名9-10岁儿童的数据。对儿童进行了为期8年的跟踪调查，以收集纵向信息，包括客观测量的体重指数（BMI）。使用多水平生长曲线模型来评估18岁时达到的BMI增长与许多环境变量之间的关联，包括公园空间和娱乐项目访问。对于距离儿童家500米以内的公园，18岁时达到的BMI与公园面积呈显著负相关。男孩的效应量大于女孩。儿童之家10公里缓冲区内的娱乐项目与18岁时BMI水平呈显著负相关，男孩的效应量也大于女孩。我们的结论是，更好地获得公园和娱乐资源的儿童不太可能经历达到BMI的显着增加。
The objective of the research was to assess how proximity to parks and recreational resources affects the development of childhood obesity through a longitudinal study. Data were collected on 3173 children aged 9–10 from 12 communities in Southern California in 1993 and 1996. Children were followed for eight years to collect longitudinal information, including objectively measured body mass index (BMI). Multilevel growth curve models were used to assess associations between attained BMI growth at age 18 and numerous environmental variables, including park space and recreational program access. For park acres within a 500 meter distance of children’s homes, there were significant inverse associations with attained BMI at age 18. Effect sizes were larger for boys than for girls. Recreation programs within a 10 km buffer of children’s homes were significantly and inversely associated with achieved levels in BMI at age 18, with effect sizes for boys also larger than those for girls. We conclude that children with better access to park and recreational resources are less likely to experience significant increases in attained BMI.
