To compare predominantly-Black and predominantly-White Maryland areas with similar socioeconomic status to examine the role of both race and socioeconomic status on tobacco outlet availability and tobacco outlet access. Maryland tobacco outlet addresses were geocoded with 2011-2015 American Community Survey sociodemographic data. Two-sample t-tests were conducted comparing the mean values of sociodemographic variables and tobacco outlet density per Census Tract, and spatial lag based regression models were conducted to analyze the direct association between covariables and tobacco outlet density while accounting for spatial dependence between and within jurisdictions. Predominantly-White jurisdictions had lower tobacco outlet availability and access than predominantly-Black jurisdictions, despite similar socioeconomic status. Spatial lag model results showed that median household income and vacant houses had consistent associations with tobacco outlet density across most of the jurisdictions analyzed, and place-based spatial lag models showed direct associations between predominantly-Black jurisdictions and tobacco outlet availability and access. Predominantly-White areas have lower levels of tobacco outlet density than predominantly-Black areas, despite both areas having similar socioeconomic statuses.
为了比较社会经济地位相似的以黑人和白人为主的马里兰州地区,以研究种族和社会经济地位对烟草销售点数量和可及性的影响。利用 2011-2015 年美国社区调查的社会人口统计数据对马里兰州的烟草销售点地址进行地理编码。通过两样本 t 检验比较了每个普查区的社会人口统计学变量和烟草销售点密度的平均值,并进行了基于空间滞后的回归模型分析,以在考虑司法管辖区之间和内部的空间依赖性的同时,分析协变量与烟草销售点密度之间的直接关联。尽管社会经济地位相似,但以白人为主要人口的司法管辖区的烟草销售点数量和可及性低于以黑人为主要人口的司法管辖区。空间滞后模型结果表明,在分析的大多数司法管辖区中,家庭中位数收入和空房率与烟草销售点密度之间存在一致的关联,而基于地点的空间滞后模型则显示了以黑人为主要人口的司法管辖区与烟草销售点数量和可及性之间的直接关联。尽管以白人和黑人为主的地区具有相似的社会经济地位,但以白人为主要人口的地区的烟草销售点密度较低。
