Street food stands (SFS) are an understudied element of the food environment. Previous SFS studies have not used a rigorous approach to document the availability, density, and distribution of SFS across neighborhood income levels and points of access in Mexico City. A random sample ( = 761) of street segments representing 20 low-, middle-, and high-income neighborhoods were assessed using geographic information system (GIS) and ground-truthing methods. All three income levels contained SFS. However, SFS availability and density were higher in middle-income neighborhoods. The distribution of SFS showed that SFS were most often found near homes, transportation centers, and worksites. SFS availability near schools may have been limited by local school policies. Additional studies are needed to further document relationships between SFS availability, density, and distribution, and current structures and processes.
街头食品摊是食品环境中一个研究不足的要素。以往对街头食品摊的研究并未采用严谨的方法来记录墨西哥城不同邻里收入水平和交通枢纽处街头食品摊的可及性、密度及分布情况。利用地理信息系统(GIS)和实地调查方法,对代表20个低收入、中等收入和高收入社区的街道段进行了随机抽样(n = 761)评估。所有三个收入水平区域均有街头食品摊。然而,中等收入社区的街头食品摊可及性和密度更高。街头食品摊的分布表明,它们最常出现在住宅、交通枢纽和工作场所附近。学校附近的街头食品摊可及性可能受到当地学校政策的限制。需要进一步开展研究,以进一步记录街头食品摊的可及性、密度和分布与当前结构及流程之间的关系。
