Environmental, social and individual factors influence eating patterns, which in turn affect the risk of many chronic diseases. This study aimed to estimate associations between environmental factors and the consumption of fruit and vegetables among adults in a Brazilian urban context. Data from the surveillance system for risk factors for chronic diseases (VIGITEL) of Brazilian Ministry of Health were used. A cross-sectional telephone survey (VIGITEL – 2008–2010) was carried out with 5826 adults in the urban area of Belo Horizonte. Individual variables were collected. The frequency of fruit and vegetables consumption was assessed from number of servings, weekly frequency and an intake score was calculated. Georeferenced variables were used to characterize the food environment. The density of healthy food outlets (stores specialized in selling fruit and vegetables), unhealthy food outlets (bars, snack bars and food trucks/trailers) and the neighborhood family income were investigated and associated with fruit and vegetables intake score. Weighted multilevel linear regression was used to evaluate the associations between the environment variables and the fruit and vegetables intake score. Higher fruit and vegetables intake scores were observed in neighborhoods with higher density of healthy food outlets and higher income. Lower scores were observed in neighborhood with higher density of unhealthy food outlets. These associations were adjusted by individual variables such as gender, age, physical activity, sugar sweetened beverages consumption, education level and smoking. The food environment might explain some of the socioeconomic disparities with respect to healthy food intake and health outcomes. Healthy food stores are less common in socially disadvantaged neighborhoods, and therefore, healthy foods such as fruits and vegetables are less available or are of a lower quality in lower income areas. Food environment characteristics and neighborhood socioeconomic level had significant associations with fruit and vegetable intake score. These are initial findings that require further investigation within the middle income world populations and the role of the environment with respect to both healthy and unhealthy food acquisition and intake.
Objective: Food delivery apps represent an important and emerging dimension of the digital food environment. This study aimed to examine food availability and the use of marketing strategies by two food delivery apps in a Brazilian metropolis.Design: An exploratory study was conducted in the city of Belo Horizonte, Minas Gerais. Food groups were identified and the use of price discounts and photos by the apps was observed.Setting: Eighteen neighbourhoods and the ten best rated restaurants in each app.Participants: Three hundred sixty-two commercial food establishments.Results: The proportion of ultra-processed beverages on offer in the apps (78·45 %) was much higher in comparison with water (48·89 %), natural juices or smoothies (27·07 %). Ultra-processed ready-to-eat meals represented almost 70 % of the food offered in the establishments’ menus, while traditional meals and vegetables represented just over 30 % of the offering. Ice cream, candies and salty packaged snacks were nine times more frequently presented than fruits. The use of photos and price discounts prevailed predominantly among ultra-processed beverages, sandwiches and ice cream, candies and salty packaged snacks. These marketing strategies were least used for promoting fruits and vegetables.Conclusions: Restaurants registered on food delivery apps offered a significant amount of ultra-processed foods with price discounts and photos in comparison with unprocessed and minimally processed foods.
This study’s aim was to characterize the food environment of Brazilian public and private schools. This was a national school-based cross-sectional study with 1,247 schools - among which 81.09% were public and 18.91% were private - in 124 Brazilian municipalities. The data originated from the Questionnaire on Aspects of the School Environment, used in the Study of Cardiovascular Risk in Adolescents (ERICA) in 2013 and 2014. Data analysis was conducted in 2017. The chi-square test was used to compare proportions. A greater proportion of public schools offered school meals (98.15%) in comparison to private schools (8.07%) (p < 0.001). The internal sale of food and beverages was more prevalent in private schools (97.75% vs. 45.06%, p < 0.001). Also, sale and advertisement of processed and ultra-processed foods (sodas, cookies, savory snacks, sandwiches and pizza), as well as the presence of vending machines for industrialized products (18.02% vs. 4%) (p < 0.001) were more common in private schools. Street vendors at the school gate or surroundings were identified in 41.32% of the public schools and 47.75% of the private schools (p > 0.05). These findings reveal the predominance of obesogenic environments mainly in private schools, and can contribute to the design of Brazilian public policies to promote a healthy school food environment.

Background: Food deserts are neighborhoods with little or no access to healthy food, whereas food swamps are neighborhoods where unhealthy food options prevail over healthy ones. The main aims of the current study are to feature and compare the neighborhoods of food deserts and food swamps based on social inequality. Methods: Ecological study carried out in Belo Horizonte City, Minas Gerais State, Brazil. Information about commercial food establishments derived from two different databases. It was measured by secondary governmental databases, which were virtually conferred in the present study. Census tracts were considered as analysis units and classified as food deserts and food swamps, based on the Brazilian methodology. Take into consideration the density of establishments classified as selling fresh or minimally-processed food, mixed establishments, and establishments selling ultra-processed food. The Brazilian methodology evaluates food deserts by the density of healthy establishments (establishments classified as mostly selling fresh or minimally-processed food and mixed establishments) per 10 thousand inhabitants. And the metric to evaluate food swamps considers the density of unhealthy establishments (establishments mostly selling ultra-processed food) per 10 thousand inhabitants. Information about social inequalities comprised aspects such as income, population count, number of households, number of literate individuals, race, water and energy supply, and garbage collection. The Health Vulnerability Index (HVI) was used as a synthetic social vulnerability indicator. Results: Neighborhoods of food deserts presented worse essential service availability, lower income per capita, and smaller mean number of literate individuals. Census tracts classified as food swamps presented better socio-demographic conditions than those areas food deserts. Neighborhoods simultaneously classified as food deserts and food swamps presented lower income per capita and were more often observed in census sectors presenting medium and high HVI. Conclusion: The food environment in Belo Horizonte was featured by the strong presence of food deserts and food swamps. However, the potential influence of these areas on food intake has changed depending on social inequalities.

OBJETIVO: avaliar a reprodutibilidade e validade de indicadores de consumo de alimentos e bebidas levantados por meio de entrevistas telefônicas pelo Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Telefone (VIGITEL). MÉTODOS: A reprodutibilidade foi aferida por meio de entrevistas repetidas com intervalos de 7 a 15 dias a partir da primeira entrevista original do sistema (n=258). A validade foi avaliada usando como padrão ouro 3 entrevistas correspondentes a recordatórios de 24h (R24h) em 3 dias da semana, após 7 a 15 dias da entrevista telefônica original (n=217). No estudo de reprodutibilidade a estatística kappa foi utilizada para medir a concordância entre os resultados das proporções obtidas na primeira e na segunda entrevista. Para a validação, a proporção de referência positiva de alimentos e bebidas na entrevista telefônica original foi comparada àquela obtida nos R24h e sua avaliação foi analisada por meio do cálculo da sensibilidade, especificidade e valor preditivo positivo. RESULTADOS: No estudo de reprodutibilidade, observou-se concordância quase perfeita para o indicador de consumo de leite com teor integral de gordura (0,86); concordância substancial para consumo de frutas (0,67), consumo de frutas e hortaliças, consumo de carne com gordura ou frango com pele e consumo abusivo de bebida alcoólica; concordância moderada para o indicador de consumo de refrigerante; e concordância regular para o indicador do consumo de hortaliças. Com relação ao estudo de validação, observou-se subestimação de indicadores de consumo de frutas, hortaliças e leite integral, exceto para consumo de carne/frango com gordura e bebida alcoólica, quando comparados com a frequência desse consumo estimada a partir dos três R24horas; as diferenças para o consumo de refrigerantes foi inexpressiva. CONCLUSÃO: Verificou-se que os instrumentos utilizados permitem a vigilância de fatores potencialmente associados a doenças não transmissíveis, entretanto, é prioritária a continuidade de estudos de validação em outras populações do sistema, com o objetivo de oferecer maior confiabilidade aos mesmos, sempre considerando as potenciais limitações.
