HAP is a focus point of the Brazilian Unified Health System to promote health through actions such as regular physical exercise and healthy eating. In the crosssectional study, we aimed to identify the nutritional status and health conditions of individuals entering in the HAP, over a three year period, in a reference site of the Program. Were registered sociodemographic data, health conditions, food intake and anthropometry. On the other hand, the ecological study evaluated stores selling groceries confined in buffers from 18 sites of the Program selected by simple conglomerate sampling strategy, stratified according to the nine administrative regions of the city. Data from the stores were obtained with the city administration. In each store were registered, by direct observation, variables as the type and location of establishments, availability, variety and advertising of fruit and vegetables (FV) and ultraprocessed foods, allowing estimating a quality index of access to food in the shops (IAFE). To verify the association between sociodemographic variables (education and income) and the type of commercial establishment, with the IAFE, HAP users residing in a radius of a 1,000m these establishments were selected. In the cross-sectional study, we found that HAP users had lower education and income, high prevalence of dietary inadequacies, such as low intake of FV (75.3%), and diseases such as hypertension and overweight. These findings indicate the need for assessing the food environment in the area of HAP. Thus, we proceeded to conduct the environmental study. From the 1,211 establishments initially identified, 385 were excluded for not commercializing FV and 72 for being duplicates in the City Hall list. A total of 754 stores were then visited. From this,46.3% (n = 349) were inexistent or inoperable and 23% (n = 172) did not commercialize FV. Of the remaining 233 stores, 13% (n = 31) refused to participate. However, establishments found spontaneously (n = 127) were also included, of which 11% (n = 14) refused to participate. A final number of 336 sites were analyzed. Most centers were not located in regions with the highest density of shops and only one-sixth of the hot areas had establishments with better access to FV. The median IAFE was 11 (5-16), and the establishments located closest to residential users (median: 319m) were mostly green groceries and street grocery markets. The IAFE was influenced by the type of establishment, and the increase of 1% in the frequency of green groceries/street grocery markets and supermarkets was associated with an increase of 0.12 and 0.07 point in the IAFE, respectively. The results point to the importance of implementing policies supporting the supply of healthy foods prioritizing intersectoral action in areas with low access to these items, allowing the construction of a healthy environment. This would improve access, availability and consumption of healthy foods, such as FV, in the population and thus contribute to overcoming health inequities. Furthermore, HAP, as a health promotion site, can have its food and nutrition education activities strengthened by the healthy territory.

The purpose of this study was to describe environmental conditions and their relationship with fruit and vegetable (FV) consumption among Brazilian public health service users in the city of Belo Horizonte. We evaluated food stores contained within 1600 m buffer zones at 18 Health Academy Programme sites, from 2013 to 2014. Variables at the community (density, proximity and type) and the consumer (sectional location of FV; availability, quality, variety, price and advertising of FV and ultra-processed foods) nutrition environment were measured by direct observation, while aggregate data from users (income and FV consumption) were obtained by interview. Data were analysed using the Kernel intensity estimator, average nearest neighbour value and Local Moran's Index for local spatial autocorrelation. We interviewed 3414 users and analysed 336 food stores. Major geographical variations in the FV consumption were identified. Average consumption was higher (site 2A: 410.5 ± 185.7 g vs. site 4B: 311.2 ± 159.9 g) in neighbourhoods with higher income and concentration of food stores, and better index of access to healthy foods. Sites with poor FV consumption had the most stores with poor access to healthy foods (index in the first tertile, ≤10). In conclusion, negative characteristics of the food environment, as seen in the present study, may contribute to low FV consumption, suggesting the need for the development and consolidation of public policies aimed at creating healthy environments through built environment interventions that increase access to and consumption of healthy foods like FV.

The study evaluated commercial food establishments within a buffer area based on a radius of 1,600 meters around each of 18 randomly selected fitness facilities. Quality of access to fruits and vegetables was assessed by the Healthy Food Store Index (HFSI), consisting of the variables availability, variety, and advertising of fruits, vegetables and ultra-processed foods. The analysis was based on calculation of the Kernel intensity estimator, nearest neighbor method, and Ripley K-function. Of the 336 food establishments, 61.3% were green grocers and open-air markets, with a median HFSI of 11 (5 to 16). In only 17% of the territories, the majority of the "hot area" establishments displayed better access to healthy foods, and only three areas showed a clustering pattern. The study showed limited access to commercial establishments supplying healthy fruits and vegetables within the territory of the public fitness program.

Ecological study conducted in Viçosa, Minas Gerais, Brazil, with all schools (N=42) and food stores (N=656). Data were collected through the objective evaluation of the environment, and the stores were categorized into healthy, unhealthy, mixed and supermarkets. Bivariate Ripley´s K function assessed the existence of clustering of categories of stores in the territory of schools. All the schools had at least one food store in their territory. Unhealthy stores were the most common and closest to the schools. There were more stores around private schools, offering high school education, located in the central region and in the highest per capita income tercile. The bivariate Ripley´s K function showed evidence of clustering of stores at all analyzed distances (400 to 1.5 km) with up to 3 times more establishments than would be expected if they were randomly distributed. Therefore, schoolc...

The proposed method is relevant to non-commercial use or scholarly purposes. We aimed to test the validity of web sources data for the assessment of community food retail environment by comparison to ground-truth observations (gold standard). A secondary aim was to test whether validity differs by type of food outlet and socioeconomic status (SES). The study area included a sample of 300 census tracts stratified by SES in two of the largest cities in Brazil, Rio de Janeiro and Belo Horizonte. The GE web service was used to develop a tool for automatic acquisition of food retail data through the generation of a regular grid of points. To test its validity, this data was compared with the ground-truth data. Compared to the 856 outlets identified in 285 census tracts by the ground-truth method, the GE interface ...
