背景：儿童肥胖和相关健康风险的流行增加导致了学校实施与营养和体育活动（NPA）相关的政策的努力。随着多方面的政策努力，存在的挑战，在整个广度的NPA policy.METHODS：汇总政策指数的特点，从2004年到2009年在阿肯色州公立学校的NPA政策实施的变化程度的特征。指数分数按年，域，和学校level.RESULTS：均数和中位数指数分数随着时间的推移而增加，在营养比体育活动的政策分数看到更大的变化。综合指数评分在很大程度上取决于营养指数评分，因此，对于我们的评价目的相对来说用处不大。政策指数得分不同的学校水平，rurality，招生规模，并有资格为联邦膳食programmes.CONCLUSIONS的学生的百分比：政策指数的方法有利于考虑学校政策变化的影响，在一个整体的，汇总的方式。学校特色影响政策的采纳，因此，在推动政策变革时应予以考虑。
BACKGROUND:Epidemic increases in childhood obesity and associated health risks are resulting in efforts to implement school policies related to nutrition and physical activity (NPA). With multicomponent policy efforts, challenges exist in characterizing the extent of policy change across the breadth of NPA policies.METHODS:Aggregated policy indices were created to characterize NPA policy implementation in Arkansas public schools from 2004 through 2009. Index scores are presented by year, domain, and school level.RESULTS:Both mean and median index scores increased over time, with greater changes seen in nutrition than in physical activity policy scores. The composite index score was heavily dependent on the nutrition index score and, thus, is relatively less useful for the purposes of our evaluation. Policy index scores varied by school level, rurality, enrollment size, and percentage of students eligible for federal meal programs.CONCLUSIONS:The policy index approach facilitates the consideration of the effect of school policy change in a holistic, aggregated way. School characteristics influence policy adoption, and thus, should be taken into consideration in the promotion of policy change.
