Rethinking the Social Determination of Food in Chile Through Practices and Interactions of Actors in Food Environments: Nonexperimental, Cross-Sectional Study.

BACKGROUND: Food environments are crucial for promoting healthy and sustainable eating and preventing obesity. However, existing food environment frameworks assume an already installed causality and do not explain how associations in food environments are established or articulated, especially from an integrative and transdisciplinary approach. This research attempts to bridge these gaps through the use of Actor-Network Theory, which traces the relationship network between human (and nonhuman) actors in order to describe how these interact and what agencies (direct or remote) are involved. OBJECTIVE: This study aims to explain the practices and interactions of actors in food environments in order to approach the problem of unhealthy eating with a transdisciplinary approach. METHODS: This is a nonexperimental, cross-sectional study. Due to the complexity of the study phenomena, a mixed methods approach with 4 consecutive phases will be developed in Chile. Phase 1 involves a systematic literature review of food environment evidence since 2015, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol; phase 2 involves the application of a shortened version of the Nutrition Environment Measure Scale-Perceptions adapted to Chile (NEMS-P-Ch) in 2 neighborhoods with different socioeconomic levels; in phase 3, six focus groups in each neighborhood will be conducted to address social determinants such as gender, employment status, and migration; and in phase 4, participant observation and in-depth interviews will be used to analyze the direct and empirical exploration of the actors in their daily interaction with food environments. The triangulation and complementarity of the data will allow us to create a practical model about the practices and interactions of actors in their food environments, which reflects the complexity and transdisciplinary nature of the study. RESULTS: We have advanced in phases 1-3 of the study. In phase 1, a total of 109 manuscripts are being revised for data extraction. In phase 2, we applied the NEMS-P-Ch to 785 people, 49.4% (388/785) of whom belong to a low socioeconomic neighborhood. Participants from phase 2 are being contacted to participate in the focus groups (phase 3). By the end of July, we have conducted 6 focus groups with 5-11 participants. CONCLUSIONS: This study will provide a comprehensive understanding of how individuals interact with their food environments, offering deep insights into the factors influencing their food-related decisions. In addition, the study aims to develop a model that more accurately reflects reality by examining not only the food environments themselves but also the interactions among various stakeholders within these environments and their daily practices. The findings of this study will offer evidence-based insights to inform public policies tailored to the specific territories and communities under investigation or those with similar characteristics.

Spatial Barriers to Transforming toward a Healthy Food System in the Noreste of Mexico.

In the past five decades, global food systems have undergone a notable transition, moving from predominantly rural settings to increasingly urban and industrialized environments, largely driven by processes of globalization and supply chain integration. However, this evolution has not adequately addressed equitable access to nutritious diets and food environments, resulting in adverse health outcomes. This study delves into the spatial and non-spatial barriers that impede the adoption of healthy diets in the Noreste of Mexico, particularly focusing on the challenges associated with accessing and cultivating plant-based foods. Through an examination of suitable areas for urban agriculture and an exploration of the socio-cultural factors influencing the adoption of plant-based diets, the research focuses on interventions aimed at promoting healthier and more sustainable eating practices in Monterrey. The findings of the study reveal significant disparities in food access across the Monterrey metropolitan area, with central urban zones exhibiting superior access to fresh foods compared to suburban and peripheral regions. This inequality disproportionately affects marginalized areas characterized by higher poverty rates, exacerbating issues of food insecurity. Nevertheless, traditional dietary practices could offer promising avenues for creating culturally significant and healthier dietary transitions, even amidst the ongoing process of urbanization.

How are intra-household dynamics, gender roles and time availability related to food access and children's diet quality during the Covid-19 lockdown?

The association between food access and children's diet quality has been documented mainly from its external dimension (e.g., availability, prices, food properties, and marketing). However, existing research has underscored that the external food environment cannot fully account for variations in children's diet quality, even amid the COVID-19 lockdown. It is increasingly evident that elements within the domestic food environment also play a crucial role in shaping this relationship. Specifically, gender roles influence how food is procured and consumed, along with challenges related to time constraints. This study explores the influence of the domestic time-gender axis and household dynamics in food access and children's dietary quality in 14 female-headed households in Santiago, Chile, during the COVID-19 lockdown. Employing a photo-elicitation exercise, we engaged with families residing in the same urban neighborhood but exhibiting varying levels of dietary quality among their children. Our analysis utilized a framework incorporating both socio-ecological food environment and gender theories. Our findings show that within these households, only one unit of "person-time" was available to address all food and caregiving tasks. Due to an unequal gender system, this limited time allocation was disproportionately absorbed by women, who were already burdened with multiple responsibilities. The lack of time favors the consumption of ultra-processed foods and hinders the intake of fresh foods. Other associated intrahousehold dynamics, such as children's fussiness and special diets, accentuates these time scarcity consequences. These difficulties were further exacerbated by strategies adopted in response to the COVID-19 lockdown, however, in families where food-related responsibilities were shared more equitably the lockdown was less disrupting. These results indicate that on top of external food environment policies, comprehensive gender-transformative policies that include food socialization processes are needed to promote healthier diets among all.

Barreras para una alimentación saludable: un análisis cualitativo de las semánticas emergentes en las comunidades escolares de Ciudad Sur

La literatura ha hecho hincapié en la centralidad que cumplen los entornos alimentarios en las elecciones alimentarias y en el estado nutricional de la población. Objetivo: identificar las percepciones de padres, madres y apoderados, profesionales de establecimientos educacionales, funcionarios municipales, y feriantes pertenecientes a la zona sur de Santiago de Chile, respecto a las barreras y limitaciones de la puesta en práctica de una alimentación saludable en el ambiente alimentario escolar. Método: se realizaron seis grupos focales agrupando a 50 actores claves vinculados a los establecimientos educacionales de Ciudad Sur utilizando una muestra no probabilística. Se aplicó un análisis de contenido mediante la técnica de codificación temática buscando relevar los universos semánticos emergentes. Resultados: se identificaron nueve barreras, o semánticas, que caracterizan limitantes a la realización de la alimentación saludable en los entornos escolares desde la perspectiva de los participantes: la familia, kioscos escolares, la salida de los establecimientos escolares, gusto, determinantes socioeconómicos, política pública, falta de conocimiento, publicidad y disponibilidad de productos sin sellos. Conclusiones: las limitaciones asociadas al ambiente alimentario doméstico tienen una representación significativamente alta (47,9%) y contienen un carácter de responsabilización individual en su enunciación. Esta cultura explicativa es opuesta a la evidencia científica y académica respecto al funcionamiento de la conducta alimentaria, y a la centralidad de los ambientes alimentarios respecto a la facilitación u obstaculización del consumo de alimentos saludables o adecuados.

Literature has emphasized on food environments centrality in food choices and nutritional status. Objective: identify social perceptions of fathers, mothers and guardians, professionals from educational establishments, municipal officials, and stallholders belonging to the southern area of Santiago de Chile, regarding limitations of healthy diet implementation on school environments. Method: six focus groups were carried out grouping 50 key actors linked to educational establishments using a non-probabilistic sample. A content analysis was applied through thematic coding technique seeking to reveal emerging semantic universes. Results: Nine barriers, or semantics, were identified characterizing limitations to healthy eating habits in school environments: family, school kiosks, leaving school establishments, taste, socioeconomic determinants, public policy, lack of knowledge, publicity, and availability of products without seals. Conclusions: limitations associated with domestic food environment have a significantly high representation (47,9%) and contain an individualized responsibility feature. This explanatory culture is opposed to scientific and academic evidence regarding the functioning of eating behavior, and the centrality of food environments facilitating or hindering healthy food consumption.

Adaptation and validation of the Perceived Nutrition Environment Measures Survey for the Chilean context (NEMS-P-Ch)

There is an increasing interest in having validated instruments that can classify food environments due to their influence on eating behavior and nutritional status. In Chile, it is not known how people perceive food environments and only a few studies have adapted instruments to the Chilean context, all of which use objective measures. The aim of this study is to present the adaptation and validation of the Perceived Nutrition Environment Measures Survey (NEMS-P-Ch) for Chile using a cross-sectional, non-probability study. First, the NEMS-P was adapted in 3 stages: cultural translation and adaptation, expert judgment (focus groups), and cognitive interviews with a population similar to the target audience. Then, the adapted questionnaire (NEMS-P for Chile, NEMS-P-Ch) was tested on people responsible for buying food in their homes in the Metropolitan Region, Chile, for statistical validation. After 200 people completed the questionnaire a final version of the NEMS-P-Ch was generated with 48 questions and seven sections that measure food environments: home, food supply, restaurants and street. NEMS-P-Ch had acceptable reliability in more than half of the questions analyzed, with Cronbach's alpha values between 0.44 and 0.82. Acceptable values were also obtained for most of the questions when the consistency of the instrument was evaluated after applying it for the second time (n= 167). The NEMS-P-Ch adapted to the Chilean context showed acceptable validity and reliability. Having instruments adapted and validated to the national reality will promote their use and adaptation in other countries of the region and thus deepen the study of food environments in various territories and populations.

El creciente interés por contar con instrumentos validados que clasifiquen los ambientes alimentarios se debe a la influencia que estos tienen en la conducta alimentaria y el estado nutricional. En Chile, se desconoce cómo las personas perciben los ambientes alimentarios y son pocos los estudios que han adaptado instrumentos al contexto chileno, todos utilizando medidas objetivas. En este estudio se presenta la adaptación y validación para Chile de la Encuesta de Medición del Entorno Nutricional Percibido (NEMS-P-Ch). Estudio transversal, no probabilístico. Inicialmente, NEMS-P fue adaptado siguiendo 3 etapas: traducción y adaptación cultural, juicio de expertos (grupos focales) y entrevistas cognitivas con población similar a la audiencia objetivo. Luego, el cuestionario adaptado (NEMS-P-Ch) fue testeado en personas responsables de la compra de alimentos del hogar, Región Metropolitana, Chile, para finalmente validarlo estadísticamente. Tras su aplicación a 200 personas, se generó la última versión de NEMS-PCh, instrumento con 48 preguntas y 7 secciones que mide los ambientes alimentarios: doméstico, de abastecimiento, restauración y vía pública. NEMS-P-Ch mostró una confiabilidad aceptable en más de la mitad de las preguntas analizadas, con valores alfa de Cronbach entre 0,44 y 0,82. También se obtuvieron valores aceptables en la mayoría de las preguntas cuando se evaluó su consistencia al aplicarlo por segunda vez (n= 167). NEMS-P-Ch adaptado al contexto chileno mostró una validez y confiabilidad aceptables. Contar con instrumentos validados a la realidad nacional promoverá su uso, su adaptación en otros países de la región y la profundización del estudio de los ambientes alimentarios en diversos territorios y poblaciones.

Food access, domestic environments, and dietary quality of low-middle income Chilean children during the COVID-19 pandemic.

Introduction: Food access is associated with dietary quality; however, people living in similar physical environments can have different food access profiles. Domestic environments may also influence how food access relates to dietary quality. We studied food access profiles of 999 low-middle income Chilean families with children during the COVID-19 lockdown and how these profiles relate to dietary quality; secondarily, we also explore the role of the domestic environment in this relationship. Materials and methods: Participants of two longitudinal studies conducted in the southeast of Santiago, Chile, answered online surveys at the beginning and end of the COVID-19 pandemic lockdown. Food access profiles were developed by a latent class analysis considering food outlets and government food transfers. Children's dietary quality was estimated by self-reported compliance with the Chilean Dietary Guidelines of Americans (DGA) and daily ultra-processed food (UPF) consumption. Logistic and linear regressions were used to assess the association between food access profiles and dietary quality. Domestic environment data (i.e., the sex of the person who buys food and cooks, meal frequency, cooking skills, etc.) were incorporated in the models to assess their influence on the relationship between food access and dietary quality. Results: We have categorized three food access profiles: Classic (70.2%), Multiple (17.9%), and Supermarket-Restaurant (11.9%). Households led by women are concentrated in the Multiple profile, while families from higher income or education levels are focused on the Supermarket-Restaurant profile. On average, children presented poor dietary quality, with a high daily UPF consumption (median = 4.4; IQR: 3) and low compliance with national DGA recommendations (median = 1.2; IQR: 2). Except for the fish recommendation (OR = 1.77, 95% CI:1.00-3.12; p: 0.048 for the Supermarket-Restaurant profile), the food access profiles were poorly associated with children's dietary quality. However, further analyses showed that domestic environment variables related to routine and time use influenced the association between food access profiles and dietary quality. Conclusion: In a sample of low-middle income Chilean families, we identified three different food access profiles that presented a socioeconomic gradient; however, these profiles did not significantly explain children's dietary quality. Studies diving deeper into household dynamics might give us some clues on intra-household behaviors and roles that could be influencing how food access relates to dietary quality.

Insistence on sameness for food space appropriation: An exploratory study on Brazilians with autism (self-)diagnosis in adulthood.

LAY ABSTRACT: Insistence on sameness is common in autistic individuals and continues into adulthood. Research shows it may be a way to cope with environments because of their sensory sensitivity, intolerance to uncertainty, and anxiety. Understanding the reasons for insistence on sameness from the perspective of autistic adults is important. To study the meanings of insistence on sameness for autistic adults, we interviewed 16 Brazilian autistic adults. All 10 formally diagnosed participants were diagnosed in adulthood. Six participants identified as being on the autism spectrum without formal diagnosis. During the interviews by email, we first asked about participants' experiences with autism diagnosis, either formal diagnosis or self-diagnosis. Then, we asked about their experiences in places for eating out and grocery shopping. We found they tended to always go to the same places and use protective accessories to eat or shop comfortably. But their such behaviors were considered weird habits, first by other people and later by themselves. While trying to control their weird habits because of social pressure, they often suffered anxiety and meltdowns. When they finally learned of their autism in adulthood, they began to better understand who they are and why they experience the environment differently from others. This new understanding taught them that their so-called weird habits are actually part of their authentically autistic ways to cope with the weirder world. This study suggests that autistic adults' insistence on sameness is an authentically autistic way to exercise their right to comfortably co-exist and live as human beings and as themselves.

Los productos ultra-procesados: Implicancias sobre su consumo, avances y retos en América Latina para la salud pública en adultos

RESUMEN La aparición de los productos ultra-procesados y su incremento en las ventas, ha propiciado modificaciones en los entornos alimentarios, condiciones que se han asociado con repercusiones negativas en la salud de las personas. El objetivo de este ensayo fue analizar las implicancias del consumo de ultra-procesados, avances y retos en América Latina para la salud pública en adultos. Para ello, se buscó información en diferentes bases de datos lo que llevó a la revisión de documentos que presentaron datos sobre el consumo, implicancias, acciones y retos de políticas públicas en torno a los productos ultra-procesados. México y Chile registraron las ventas per cápita más altas de América Latina. Las altas ventas de estos productos, el incremento de establecimientos de comida rápida, así como de supermercados, se ha asociado con el aumento de la prevalencia de sobrepeso, obesidad y DM2 en la región; asimismo se detectaron avances en materia de políticas públicas y fiscales que han sido emitidas por los Estados para la mejora de la información la cual advierte de los riesgos a la salud de estos productos así como el incremento de impuestos a productos con perfiles nutrimentales inadecuados. Si bien, estas acciones han comenzado a evidenciar efectos positivos al registrarse decrementos en los consumos de productos ultra-procesados, es importante generar políticas y acciones que ofrezcan alternativas de consumo de alimentos mínimamente procesados, con perfiles nutrimentales adecuados y, económicamente asequibles que permitan a la población tener alternativas de consumo distintas a los ultra-procesados.

ABSTRACT The appearance of ultra-processed foods (UPF) and their increase in sales has led to changes in food environments; these conditions are associated with negative repercussions on people's health. Therefore, this essay aimed to analyze the implications of the consumption of UPF, advances, and challenges in Latin America for public health in adults. The information was collected in different databases, which led to the review of documents that revealed data on consumption, implications, actions, and public policy challenges around UPF. Mexico and Chile were the countries with the highest per capita sales in Latin America. In the region, the prevalence of overweight, obesity, and type 2 diabetes mellitus was associated with high sales of UPF and an increase in fast-food establishments and supermarkets. Several countries in the region have issued advances in public and fiscal policies as improving the information that warns of the health risks of these products and an increase in taxes on products with inadequate nutritional profiles. Although these actions have begun to show positive effects by registering decreases in the consumption of UPF, it is essential to generate policies and actions that offer alternatives for the consumption of minimally processed foods, with adequate nutritional profiles that are affordable and allow the population to have consumption alternatives to UPF.

Changes in Food Environment Patterns in the Metropolitan Area of the Valley of Mexico, 2010-2020.

The concept of food environment refers to the opportunities; environments; and physical, economic, political, and socio-cultural conditions that frame the interaction of people with the food system and shape decisions about food acquisition and consumption. This study analyzes the relationships between the characteristics of urban environments and the availability of retail food through the evaluation of physical and financial access to food in the Metropolitan Area of the Valley of Mexico (MAVM) between 2010 and 2020. Using Geographic Information Systems (GISs), both physical access through network distance to economic food retail units and financial access through socioeconomic status at the block scale were evaluated. The network distance and socioeconomic status results were used as criteria for the spatially explicit classification of the MAVM into food deserts, oases, and swamps. Food deserts are the most abundant food environments but only increased in the third and fourth metropolitan contours. Swamps have increased throughout the city, related to the proliferation of convenience stores that have replaced grocery stores. This study contributes evidence at a local and regional scale required for the future urban planning of the MAVM and for public health and sustainability programs focusing on treating food-related diseases.

Food Availability in Different Food Environments Surrounding Schools in a Vulnerable Urban Area of Santiago, Chile: Exploring Socioeconomic Determinants.

The analysis of the food environment is used to identify areas with gaps in the availability of healthy foods and can be used as a public policy assessment tool. In recent decades, Chile has implemented several strategies and regulations to improve food environments, with encouraging results. Little is known about the scope of these measures in socially vulnerable environments. This study is part of a project that seeks to build an integrated intervention model for healthy school environments in a vulnerable area of Santiago, Chile. The objective of this study was to evaluate the availability of healthy and unhealthy foods around schools and the relationship between it and socioeconomic determinants of the school community in the Chilean context. A cross-sectional study to measure the food environment of informal markets (street food), formal markets (stores), and institutions (schools) was conducted in and around 12 schools (100 m surrounding schools) in a vulnerable urban area of Santiago, Chile. A lack of healthy foods was observed, which was related to some socio-economic determinants and the multidimensional poverty was the most relevant. The diagnosis of food environments around schools can represent an important target for governments to implement policies focused at improving the availability of healthy foods.

Ambientes y hábitos alimentarios: Un estudio cualitativo sobre cambios producidos durante la pandemia por Covid-19 en estudiantes universitarios

RESUMEN La pandemia por Covid-19 ha generado diversos cambios en la rutina diaria de las personas a nivel mundial, repercutiendo en los ambientes alimentarios habituales y hábitos relacionados. En los estudiantes universitarios, el cambio en los ambientes alimentarios ha impactado fuertemente debido al cierre de las casas de estudio. Sin embargo, existe escasa información en el país, acerca de las consecuencias que dicha modificación ha provocado. El objetivo fue explorar cómo han cambiado los ambientes y hábitos alimentarios de universitarios, debido a la pandemia por Covid-19. Se llevó a cabo un estudio transversal de tipo cualitativo. Los participantes fueron estudiantes pertenecientes a una facultad de una universidad pública de Chile. Se realizaron 15 entrevistas semiestructuradas en modalidad online. La narrativa de las entrevistas se analizó a través de un análisis temático, con un enfoque inductivo. Los resultados muestran dos temas principales: I) Compra y acceso a alimentos, en donde no se visualizaron grandes cambios en el ambiente de abastecimiento, pero si en los ambientes alimentarios de restauración y vía pública; II) Transición desde el ambiente alimentario institucional al doméstico, situación que modificó los hábitos alimentarios en la mayoría de los estudiantes, quienes declararon consumir preparaciones más caseras, además de percibir mayor tiempo disponible al momento de consumir alimentos, en comparación a aquel dado en contexto universitario pre pandémico. Se requiere reflexionar acerca de cómo los aspectos positivos en los ambientes y hábitos alimentarios pudieran favorecerse en una vuelta a la presencialidad en el ambiente académico.

ABSTRACT The COVID-19 pandemic has generated various changes in the daily routine of people worldwide, affecting the usual food environments and related habits. Among university students, the change in food environments has had a strong impact due to the closure of university campuses. However, there is little information in the country about the consequences that this modification has caused. The study aim was to explore how the environments and eating habits of university students changed due to the COVID-19 pandemic. A qualitative descriptive cross-sectional study was carried out. Participants correspond to students of a public university in Chile. Fifteen semi-structured interviews were conducted online. Interview narratives were analyzed through a thematic analysis, using an inductive approach. The results show two main themes: I) Purchase and access to food, where great changes were not seen in the supply environment, but in the food environments of restaurants and public roads; II) Transition from the institutional food environment to the domestic environment, a situation that modified the eating habits of most of the students, who declared consuming more homemade preparations, in addition to perceiving more time available at the time of consuming food, compared to that given in context pre-pandemic college. It is necessary to reflect on how the positive aspects in the environments and eating habits could be favored in a return to the presence in the academic environment.

Food environments and the COVID-19 pandemic in Brazil: analysis of changes observed in 2020.

Evidence of changes caused by the COVID-19 pandemic in food security and nutrition conditions, as well as in different food environments, has called researchers' attention to substantial changes taking place in individuals' dietary habits. The aim of this study is to present and address changes that have already happened in food environments, during the first COVID-19 pandemic year, in a middle-income country. Multiple changes were observed and had direct impact on the population, among them, worsened health and nutrition indicators and advanced dietary inequalities, as well as on its food profile in different life cycles, if one takes into consideration aspects such as food availability, financial access and dietary quality.

Social and cultural influences on food choices: A review.

Human food choices (FC) influence food production systems. Agriculture is responsible for feeding the entire population, and somehow generates different types of environmental degradation. Consumers play a decisive role in consumption trends because FC has shaped habits and behaviors. Food is an expression of people's identity, values, and lifestyle. The objective of this article is to analyze the factors that influence FC and to consider intervention strategies used to work on improving behaviors and FC. The influence of socio-cultural aspects, such as cultural capital, social stratifications, and the inequalities could possibly trigger consumers' FC. The effects of different factors such as foodscapes, social environments, tastes, and even nutritional information, have generated that, the consumer chooses a product under pressure or makes an uninformed choice that generally is unhealthy. Restricting food accessibility generates a reactive but non-aware action, so it is necessary to work creating a sustainable food culture, with the first step of consumers being self-aware of their current FC.

Escolhas alimentares no contexto de um município com relevante produção agrícola: a perspectiva dos ambientes alimentares em Palmeira das Missões-RS / Food choices in the context of a relevant agricultural production municipality: the food environment perspective in Palmeira das Missões-RS

Introdução: Os ambientes alimentares podem ser entendidos como o contexto em que os indivíduos acessam e realizam suas escolhas alimentares, podendo favorecer ou não a alimentação saudável e adequada. Objetivo: Analisar as escolhas alimentares de consumidores urbanos na perspectiva de ambientes alimentares em Palmeira das Missões, no Rio Grande do Sul. Métodos: Estudo de abordagem qualitativa, que utilizou como técnica de pesquisa entrevista semiestruturada com consumidores residentes na área urbana no município. Os dados foram analisados por meio da análise de conteúdo por categorias temáticas, a partir das dimensões física, econômica, política e sociocultural, as quais compõem os ambientes alimentares. Resultados e Discussões: As escolhas alimentares estão interseccionadas com a ampla disponibilidade e facilidade para encontrar mais alimentos ultraprocessados do que in natura, bem como com as condições econômicas, que se tornam limitadoras das escolhas alimentares pautadas na variedade e inclusão de alimentos in natura e minimamente processados. Constatou-se a importância do Programa Bolsa Família para a aquisição de alimentos, sobretudo para famílias de menores estratos socioeconômicos. Considerações finais: Os dados da pesquisa indicam que escolhas alimentares que incluem maior variedade e disponibilidade de alimentos in natura estão associadas principalmente às condições econômicas e à disponibilidade desses alimentos. Por isso, destaca-se a importância do fortalecimento de políticas públicas para a promoção da alimentação adequada e saudável, bem como a relevância da articulação de ações locais, tendo em vista o potencial agrícola do município.

Introduction: Food environments can be understood as the context in which individuals access and make their food choices, which may or may not favor healthy and adequate food. Objective: To analyze the food choices of urban consumers from the perspective of food environments in Palmeira das Missões, in Rio Grande do Sul. Methods: Qualitative approach research, based on semi-structured interviews with consumers living in the urban area of Palmeira das Missões. Data were analyzed through content analysis by thematic categories, from the physical, economic, political and sociocultural dimensions, both related to food environments. Results and Discussions: Food choices are intersected with the wide availability and ease of finding more ultra-processed foods than in natura, as well as with the economic conditions, which become limiting of food choices based on the variety and inclusion of fresh and minimal processed foods. The importance of the Bolsa Família Program for the purchase of food was verified, especially for families from lower socioeconomic strata. Final considerations: The research findings indicate that food choices based on greater variety and availability of fresh foods are mainly associated with economic conditions and availability of these foods. Therefore, the importance of strengthening public policies for the promotion of adequate and healthy food is highlighted, as well as the relevance of articulating local actions, considering the municipality's agricultural potential.

The INFORMAS healthy food environment policy index (Food-EPI) in Mexico: An assessment of implementation gaps and priority recommendations.

Mexico is one of the countries with the highest prevalence of obesity and recently declared a national epidemic of diabetes. Healthy food environments have the potential to improve the diet of the population and decrease the burden of disease. The aim of the study was to assess the efforts of the Mexican Government towards creating healthier food environments using the Healthy Food Environment Policy Index (Food-EPI). The tool was developed by the International Network for Food and Obesity/Non-communicable Diseases Research, Monitoring and Action Support (INFORMAS). Then, it was adapted to the Latin-American context and assessed the components of policy and infrastructure support. Actors from academia, civil society, government, and food industry assessed the level of implementation of food policies compared with international best practices. Actors were classified as (1) independents from academia and civil society (n = 36), (2) government (n = 28), and (3) industry (n = 6). The indicators with the highest percentage of implementation were those related to monitoring and intelligence. Those related to food retail were rated lowest. When stratified by type of actor, the government officials rated several indicators at a higher percentage of implementation compared with independent actors. None of the indicators were rated at high implementation. Government officials and independent actors agreed upon nine priority actions to improve the food environment in Mexico. These actions have the potential to improve government commitment and advocacy efforts to create healthier food environments.

Food deserts or food swamps?: A mixed-methods study of local food environments in a Mexican city.

Differential access to healthy foods has been hypothesized to contribute to disparities in eating behaviors and health outcomes. While food deserts have been researched extensively in developed Anglophone countries, evidence from low- and middle-income countries is still scarce. In Mexico, prevalence of obesity is among the highest worldwide. As obesity has increased nationally and become a widespread public health issue, it is becoming concentrated in the low-income population. This mixed-methods study uses a multidimensional approach to analyze food environments in a low-, middle-, and high-income community in a Mexican city. The study advances understanding of the role that food environments may play in shaping eating patterns by analyzing the density and proximity of food outlet types as well as the variety, quantity, quality, pricing, and promotion of different foods. These measures are combined with in-depth qualitative research with families in the communities, including photo elicitation, to assess perceptions of food access. The central aims of the research were to evaluate physical and economic access and exposure to healthy and unhealthy foods in communities of differing socioeconomic status as well as participants' subjective perceptions of such access and exposure. The findings suggest a need to reach beyond a narrow focus on food store types and the distance from residence to grocery stores when analyzing food access. Results show that excessive access and exposure to unhealthy foods and drinks, or "food swamps," may be a greater concern than food deserts for obesity-prevention policy in Mexico.
