Item Does access to healthy food vary according to socioeconomic status and to food store type? : an ecologic study.(2019) Costa, Bruna Vieira de Lima; Menezes, Mariana Carvalho de; Oliveira, Cláudia Di Lorenzo; Mingoti, Sueli Aparecida; Jaime, Patricia Constante; Caiaffa, Waleska Teixeira; Lopes, Aline Cristine SouzaBackground: The food environment can influence opportunities and barriers to food access. This study aimed to investigate whether access to healthy foods varies according to store types and the socioeconomic status of the users of the public health promotion program in Brazil, known as the Health Academy Program. Methods: A total of 18 Health Academy Program centers were selected via simple conglomerate sampling. Health Academy Program users living up to 1 km from the food stores were evaluated (n = 2831). Their socioeconomic status was investigated via face-to-face interviews. The food stores were audited through direct observation. Variables included the community nutrition environment (type and location) and consumer nutrition environment (healthy food store index, involving variables such as availability, variety, and advertising of healthy and unhealthy products). Multiple linear regression analysis was performed to examine the association between access to healthy foods, socioeconomic status, and food store type. Results: A total of 336 stores were investigated. The majority were specialty fruit and vegetable markets/stores or open-air food markets. Access to healthy food was only associated with the food store type. An increase of 1% in the availability of specialized fruits and vegetable markets or open-air food markets and supermarket raised healthy food store index values by 0.12 and 0.07, respectively. Conclusions: Public food supply policies aimed at improving the diet quality of the population and reducing inequality in access should prioritize the implementation of stores of better quality, such as specialty fruit and vegetable markets and open-air food markets.Item Web data mining : validity of data from Google Earth for food retail evaluation.(2020) Menezes, Mariana Carvalho de; Matos, Vanderlei Pascoal de; Pina, Maria de Fátima de; Costa, Bruna Vieira de Lima; Mendes, Larissa Loures; Pessoa, Milene Cristine; Souza Junior, Paulo Roberto Borges de; Friche, Amélia Augusta de Lima; Caiaffa, Waleska Teixeira; Cardoso, Leticia de OliveiraTo overcome the challenge of obtaining accu- rate data on community food retail, we developed an innovative tool to automatically capture food retail data from Google Earth (GE). The proposed method is rele- vant 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 strati- fied 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 iden- tified in 285 census tracts by the ground-truth method, the GE interface identified 731 outlets. In both cities, the GE interface scored moderate to excellent compared to the ground-truth data across all of the validity measures: sensitivity, specificity, positive predictive value, negative predictive value and accuracy (ranging from 66.3 to 100%). The validity did not differ by SES strata. Super- markets, convenience stores and restaurants yielded bet- ter results than other store types. To our knowledge, this research is the first to investigate using GE as a tool to capture community food retail data. Our results suggest that the GE interface could be used to measure the community food environment. Validity was satisfactory for different SES areas and types of outlets.
