Food Availability, Accessibility, and Affordability through the Scope of Food Security Level and Food Environment Perception in Mexico City’s Marginated Area

Background: Food availability, accessibility, utilization, and stability, the four pillars of food security, have sound impact on food environment activities, regarding households’ food availability, accessibility, and affordability. Food availability implies the adequate supply of healthy food and food accessibility complements and builds on food availability by ensuring that households are able to obtain that food, and that food affordability is limited by incomes and food prices. Methods: In this research, socioeconomic characteristics, food security status and food environment (food availability, accessibility, and affordability) perception of households in Ecatepec, México, a marginal Mexico City conurbation area, were determined with the adequate survey. The collected data were analyzed by logistic regression to stablish the significant relationship among the independent variables (household food security status) with the socioeconomic features, in addition to food environment perception, in order to determinate which facts were significant with food security in this marginal area. Results: Educational level (P<0.001), household income (P<0.001), and belonging to a social assistance program (P<0.001) have a significant effect on food security status. Households with lower income, with food insecurity status, presented lower purchasing power. In contrast, households with food security and mild food insecurity were less likely to agree with the food that they can purchase. A better income, and therefore, a higher purchasing power was reflected in the need to access to more healthy food within their neighborhood. Conclusion: Results indicate that the food environment in this marginal area is benevolent, and households find a way to remain resilient in order to provide enough food for their families. Public policies must be focused on reducing poverty and giving more opportunities to promote social mobility
