Resumo: | This paper presents a spatial and quantitative approach to identify patterns of access to food retail and its association with urban marginalization in Mexico City. The spatial distribution of food establishments was identified using the moving windows method, in a scale of analysis of 100 m2, to delimitate areas with differentiated access to healthy and unhealthy outlets. This method revealed the spatial patterns of access to retail food outlets that are manifested with large areas of downtown, north, and east of the city exposed to an unhealthy retail food environment, while the peripheral areas of the south and southeast are under the influence of food deserts. It was revealed that 21.9% of the urban territory of the city is a healthy food environment and is distributed in the south and west of the city. It was also found that the population with the highest levels of marginalization and with medium levels are those who are exposed to unhealthy retail food environments. Chi-square test and a bivariate regression were used to determine associations between marginalization levels of the population, types of retail food environments, schooling and population density. The results indicate an association between high levels of marginalization and limited or limited access to healthy food environments, as well as a negative relationship between low levels of schooling and the density of unhealthy foods in the territory. Keywords: Food access; retail food environment; food spatial disparities. |

SPATIAL PATTERNS OF ACCESS TO RETAIL FOOD OUTLETS IN MEXICO CITYArtigosThis paper presents a spatial and quantitative approach to identify patterns of access to food retail and its association with urban marginalization in Mexico City.

La distribución espacial de los establecimientos de alimentos se identificó mediante el método de ventanas móviles, en una escala de análisis de 100 m2, para delimitar áreas con acceso diferenciado a puntos de venta saludables y no saludables. Este método reveló que los patrones espaciales de acceso a los establecimientos minoristas de alimentos se manifiestan con grandes áreas del centro, norte y este de la ciudad están expuestas a un entorno alimentario poco saludable, mientras que las áreas periféricas del sur y sureste están bajo la influencia de los desiertos alimentarios. Se reveló que el 21,9% del territorio urbano de la ciudad es un entorno de alimentación saludable y se distribuye al sur y oeste de la ciudad. También se encontró que la población con los niveles más altos de marginación, y con niveles medios, es la que está expuesta a entornos de alimentos minoristas poco saludables. Se utilizaron las pruebas de Chi-cuadrada y regresión bivariada para determinar las asociaciones entre los niveles de marginación de la población, los tipos de entorno alimentario al por menor, la escolarización y la densidad de población. Los resultados indican una asociación entre los altos niveles de marginación y el acceso reducido o limitado a entornos alimentarios saludables, así como una relación negativa entre los bajos niveles de escolaridad y la densidad de alimentos poco saludables en el territorio. Palabras clave: Acceso a los alimentos, ambiente alimentario minorista, disparidades espaciales alimentarias.PADRÕES TERRITORIAIS DO ACESSO AO RETALHO ALIMENTAR NA CIDADE DO MÉXICO Este artigo apresenta uma abordagem espacial, e quantitativa, para identificar padrões de acesso ao retalho alimentar e sua associação com a marginalização urbana na Cidade do México. A distribuição espacial dos estabelecimentos alimentares foi identificada pelo método das janelas móveis, numa escala de análise de 100 m2, para delimitar áreas com acesso diferenciado a estabelecimentos saudáveis e não saudáveis. Este método revelou que os padrões espaciais de acesso a lojas de retalho, que se manifestam em grandes áreas do centro, norte e leste da cidade, estão expostos a um ambiente insalubre de alimentos, enquanto as áreas periféricas do sul e sudeste estão sob a influência de desertos de alimentos. Foi revelado que 21,9% do território urbano da cidade é um ambiente de alimentação saudável, distribuindo-se pelo sul e oeste da cidade. Verificou-se também que a população com os níveis mais elevados de marginalização, e com níveis médios, são aqueles que estão expostos a ambientes insalubres de alimentos no retalho. O teste do Qui-quadrado e a regressão bivariada foram utilizados para determinar associações entre os níveis de marginalização da população, os tipos de ambientes alimentares no retalho, a escolaridade e a densidade populacional. Os resultados indicam uma associação entre altos níveis de marginalização e baixo acesso aos ambientes alimentares saudáveis, além de uma relação negativa entre os baixos níveis de escolaridade e a densidade de alimentos não saudáveis no território.
