背景社区健康食品的可获得性仍然是贫困社区饮食和饮食相关疾病的关键决定因素。“食物沙漠”问题的创新解决方案包括部署移动的市场和健康的街角商店计划。然而，这些举措并不总是利用指导零售业发展的原则和地理信息系统数据的可能性。同时，社区合作伙伴并不总是有效地参与这些干预措施的规划，这限制了接受性和适合性的工作，MethodsThis强调了参与性的绘图工作的结果，以优化选址的计划健康食品零售干预弗林特，密歇根州。潜在地点的选择是通过聘请专家在一个三阶段的绘图过程，其中包括层次分析法和点分配的五个关键变量（包括食物获取、社会经济困境、人口密度、交通便利和邻近社区中心），以及直接绘制合适的地点。结果结果表明，一组离散的地区-主要是在城市的西北象限-那里小-大规模的健康食品零售干预可能是最具战略意义的。直接映射的网站和非常高的适用性水平之间的最一致的重叠区域与远离现有的杂货店的社区一致。ConclusionsAs一个以社区为基础的策略，这增加了机会，有效地提高邻里获得健康食品的健康食品的潜在网站的优化干预措施。社区合作伙伴已经积极利用这些成果进行项目规划，以便采取这种干预措施。
BackgroundThe availability of healthy foods in a neighborhood remains a key determinant of diet and diet-related disease in disadvantaged communities. Innovative solutions to the ‘food desert’ problem include the deployment of mobile markets and healthy corner store initiatives. Such initiatives, however, do not always capitalize on the principles guiding retail development and the possibilities of GIS-based data. Simultaneously, community partners are not always engaged effectively in the planning for such interventions, which limits acceptability and suitability of such work.MethodsThis paper highlights the results of a participatory mapping exercise to optimize the siting of a planned healthy food retail intervention in Flint, Michigan. Potential sites are chosen by engaging experts in a three-stage mapping process that includes the analytic hierarchy process and point allocation of five key variables (including food access, socioeconomic distress, population density, access to transit, and proximity to neighborhood centers), as well as direct mapping of suitable sites.ResultsResults suggest a discrete set of areas—primarily in the northwestern quadrant of the city—where small-scale healthy food retail interventions might be most strategically located. Areas with the most consistent overlap between directly mapped sites and very high levels of suitability align well with neighborhoods which are distant from existing grocery stores.ConclusionsAs a community-based strategy, this increases the opportunity for effectively improving neighborhood access to healthy foods by optimizing the potential sites for healthy food interventions. Community partners have already been active in using these results in project planning for just such an intervention.
