SUMMARY:

 

Introduction: The food environment is the physical, economic, political and sociocultural context in which each consumer engages with the food system to acquire, prepare and consume food. This environment involves the availability, accessibility, convenience, promotion, quality and sustainability of food. Compromising access to and availability of healthy foods in sufficient quantities characterizes food insecurity. Objective: To analyze the food environment and its relationship with the occurrence of food insecurity at home and socioeconomic conditions. Method: It is a study of different methods. 1) Systematic review on the relationship between food environments and food insecurity, based on a systematic literature search in the PubMed, Web of Science, Science Direct, EMBASE and LILACS databases in January 2023. 2) Ecological study with census tracts of the city of Natal-RN, based on the identification of food acquisition establishments, grouped in the categories of in-natura or minimally processed, ultra-processed or mixed. Food deserts were calculated by the density of healthy establishments divided by 10,000 inhabitants and classified as less than or equal to the 25th percentile. We used socioeconomic data from the 2010 Census. Multiple Poisson regression was used to observe the relationship between the existence of food deserts and swamps and social infrastructure. 3) This is a quantitative and cross-sectional study with individual demographic, socioeconomic and food insecurity data from the Brazuca Natal Study and the relationship with the census tracts classified into deserts and food swamps. Results: In the systematic review, 22 articles were included, 18 of which found an association between food environments and food (in)security, the majority being in developed countries, in the global North. In the ecological study, it was identified that 51.45% of the food acquisition establishments in the city were of the ultra-processed type. There was a higher density of food establishments in regions with better socioeconomic conditions. The census tracts classified as food deserts (25%) were associated with household conditions and worse infrastructure in the sector. While 75% were identified as a food swamp, associated with better infrastructure in the sector. In the cross-sectional study, food insecurity was found in 42.3% of respondents, associated with individual and sector demographic and socioeconomic variables. Deserts and food swamps did not show a spatial distribution pattern and were not associated with food insecurity. Conclusion: There are inequalities in the distribution of different food acquisition establishments in the city of Natal/RN, with a predominance of food swamps. Thus, actions are needed to improve the sectors' infrastructure, decentralize the supply of healthy foods and limit the sale of ultra-processed foods, with a view to ensuring healthy food choices. It is important that new studies assess the different dimensions of the food environment, to allow a better identification of factors associated with food insecurity in different socioeconomic contexts.
