We conducted an ecologic analysis to determine whether housing characteristics mediate the associations between concentration of poverty and pediatric injury and between concentration of racial minorities and pediatric injury and whether the association between housing conditions and pediatric injury is independent of other risks.
We created a hierarchical data set by linking individual-level data for pediatric injury with census data. Effect sizes were estimated with a Poisson model.
After adjustment for owner occupancy and the percentage of housing built before 1950, the association between concentration of poverty and pediatric injury was attenuated. For concentration of racial minorities, only percentage of owner occupancy had some mediating effect. In hierarchical models, housing characteristics remained independent and significant predictors of pediatric injury.
The association between community characteristics and pediatric injury is partially mediated by housing conditions. Risk of pediatric injury associated with housing conditions is independent of other risks.
我们进行了一项生态学分析,以确定住房特征是否介导了贫困集中度与儿童伤害之间的关联、少数族裔集中度与儿童伤害之间的关联,以及住房条件与儿童伤害之间的关联是否独立于其他风险因素。
我们通过将儿童伤害的个体层面数据与人口普查数据相链接,创建了一个分层数据集。效应量采用泊松模型进行估计。
在对自有住房占有率和1950年以前建造的房屋百分比进行调整后,贫困集中度与儿童伤害之间的关联减弱。对于少数族裔集中度,只有自有住房占有率百分比具有一定的中介作用。在分层模型中,住房特征仍然是儿童伤害的独立且显著的预测因素。
社区特征与儿童伤害之间的关联部分由住房条件介导。与住房条件相关的儿童伤害风险独立于其他风险因素。
