健康食物资源的地理获取仍然是研究的一个主要重点，研究了建筑物的贡献。环境，健康饮食。用于定义和测量空间可达性的方法可以显着影响结果。考虑到对市场营销，政策和计划的影响，充分衡量食品环境是重要的，很少有出版的工作石油食品获取集中在石油农村地区，那里的营养相关疾病的负担更大。本文旨在扩大我们对美国农村地区粮食资源潜在空间可及性测量所面临挑战的理解。（1）在认识到市场因素可能发生变化的情况下界定农村食品环境，（2）描述可能区分类似类型食品商店和食品服务场所的特征;以及（3）确定食品商店和食品服务场所的位置坐标。为了加强农村地区的测量，“地面实况”方法，包括现场观测和收集全球定位系统数据，应成为农村地区的标准。衡量还必须认识到新的和不断变化的商店形式的出现。应努力确定从家庭以外的出发点到某一地点的接近程度和某一特定缓冲区内的多个地点的接近程度，并考虑多用途旅行和旅行链。衡量获得粮食的机会对于以社区为基础的办法满足饮食需要至关重要。研究人员必须愿意采取必要的步骤，严格测量它的动态食品环境。
Geographic access to healthy food resources remains a major focus of research that examines the contribution of the built. environment to healthful eating. Methods used to define and measure spatial accessibility can significantly affect the results. Considering the implications for marketing, policy, and programs, adequate measurement of the food environment is important, Little of the published work oil food access has focused oil rural areas, where the burden of nutrition-related disease is greater. This article seeks to expand our understanding of the challenges to measurement of potential spatial access to food resources in rural areas in the U.S. Key challenges to the accurate measurement. of the food environment in rural areas include: (1) defining the rural food environment while recognizing that market factors may be changing, (2) describing characteristics that may differentiate similar types of food stores and food-service places; and (3) determining location coordinates for food stores and food-service places.In order to enhance measurements in rural areas, "ground-truthed" methodology, which includes on-site observation and collection of GPS data, should become the standard for rural areas. Measurement must also recognize the emergence of new and changing store formats. Efforts Should be made to determine accessibility, in terms of both proximity to a single location and variety of multiple locations within a specified buffer, from origins other than the home, and consider multipurpose trips and trip chaining. The measurement of food access will be critical for community-based approaches to meet dietary needs. Researchers must be willing to take the steps necessary for rigorous measurement of it dynamic food environment.
