Changing the built environment is a sound, but often underutilized approach to injury control. The authors reviewed the literature and conducted a meta-analysis to synthesize the evidence on the association of roadway characteristics with risk of pediatric pedestrian injury. To synthesize the data, they converted results to odds ratios based on direct results or abstracted outcomes and used Bayesian meta-analytic approaches by modeling outcomes as the logit of a normally distributed set of outcomes with vague prior distributions for the central measure of effect and its variance. On the basis of 10 studies of roadway features restricted exclusively to pediatric populations, the synthesized effect estimate for the association of roadway characteristics with pedestrian injury risk was 2.5 (95% credible interval: 1.8, 3.2). The probability of a new study showing an association between the built roadway and pediatric pedestrian injury was nearly 100%. The authors concluded that the built environment is directly related to the risk of pedestrian injury. This review and meta-analysis suggests that even modest interventions to the built roadway environment may result in meaningful reductions in the risk of pediatric pedestrian injury.

巷道特征和小儿行人受伤。

更改建筑环境是一种合理的方法，但通常未充分利用来进行伤害控制。作者回顾了文献并进行了荟萃分析，综合了有关道路特征与小儿行人受伤风险之间关系的证据。为了合成数据，他们基于直接结果或抽象结果将结果转换为优势比，并使用贝叶斯元分析方法，通过将结果建模为具有模糊先验分布的正态结果集的对数，以对效果及其影响进行集中评估。方差。在仅针对小儿人群的10条道路特征研究的基础上，将道路特征与行人受伤风险相关联的综合效果估计为2.5（95％可信区间：1.8、3.2）。一项新研究显示，已建道路与小儿行人受伤之间存在关联的可能性几乎为100％。作者得出的结论是，建筑环境与行人受伤的风险直接相关。这项审查和荟萃分析表明，即使对已建成的道路环境进行适度的干预，也可能会导致有意义的降低小儿行人受伤的风险。
