更容易获得地理空间技术，导致空间化公共卫生研究激增，其中大部分集中在粮食环境上。本研究旨在分析北卡罗来纳州东部育龄妇女接触超市和农贸市场的不同空间测量方法。暴露的措施，来自使用参与者定义的社区，制造商定义的道路网络社区，并将参与者的时空行为的活动空间。结果显示，参与者定义的社区的平均面积（0.04平方米）。英里）远小于2.0英里的道路网络社区（3.11平方英里）。英里）和活动空间（26.36平方米）。英里），活动空间提供了最大的市场曝光。传统的住宅区概念可能并不适用于所有地方。捕捉活动空间的时空方法可能更相关，特别是如果与混合方法战略相结合。
Greater accessibility to geospatial technologies has led to a surge of spatialized public health research, much of which has focused on food environments. The purpose of this study was to analyze differing spatial measures of exposure to supermarkets and farmers’ markets among women of reproductive age in eastern North Carolina. Exposure measures were derived using participant-defined neighborhoods, investigator-defined road network neighborhoods, and activity spaces incorporating participants’ time space behaviors. Results showed that mean area for participant-defined neighborhoods (0.04 sq. miles) was much smaller than 2.0 mile road network neighborhoods (3.11 sq. miles) and activity spaces (26.36 sq. miles), and that activity spaces provided the greatest market exposure. The traditional residential neighborhood concept may not be particularly relevant for all places. Time-space approaches capturing activity space may be more relevant, particularly if integrated with mixed methods strategies.
