The objective of this study was to identify the food vendor distribution profile of the city of Florianópolis, Santa Catarina State, Brazil, and investigate its association with the socioeconomic and demographic characteristics of different municipal regions. This descriptive, cross-sectional study obtained the location of food vendors from secondary data from different institutional sources. The density of different types of food vendors per 1,000 inhabitants in each municipal weighted area was calculated. The Kruskal-Wallis test compared the mean density of food vendors and the weighted income areas. The lowest-income regions had the lowest density of butchers, snack bars, supermarkets, bakeries/pastry shops, natural product stores, juice bars, and convenience stores. The identification of these areas may encourage the creation of public policies that facilitate healthy food startups and/or maintenance of healthy food vendors, especially in the lowest-income regions.

Disponibilidade espacial de peixarias em áreas de diferentes níveis socioeconômicos de uma cidade litorânea Spatial availability of fish stores in areas of different socioeconomic levels of a coast city ResumoIntrodução: O consumo de alimentos in natura tem sido estimulado por diversas políticas públicas. Investigações sobre disponibilidade geográfica de locais que comercializam esses alimentos e sua relação com a qualidade da alimentação da população têm sido enfatizadas desde o início do século XXI. Objetivo: Identificar a distribuição espacial das peixarias fixas e itinerantes no município de Florianópolis, de acordo com a densidade de estabelecimentos por habitantes, em áreas geográficas de diferentes níveis de renda domiciliar. Metodologia: As informações foram obtidas por meio de dados secundários provenientes do setor de Vigilância Sanitária Municipal e de listas telefônicas digitais e impressas. Para a localização geográfica dos estabelecimentos nas 30 áreas de ponderação do município, foi utilizado o software Google Earth ® . Resultados e discussão: A distribuição espacial das peixarias fixas não contempla 14 (47%) das áreas geográficas de Florianópolis, sendo 9 (64%) atendidas pelo "Projeto Caminhão do Peixe", caracterizado pela comercialização itinerante de pescados. Apesar de não haver diferença estatística, observou-se que os números absoluto e relativo (por habitantes) das peixarias fixas eram mais altos quanto maior era a renda da área geográfica. Conclusões: Recomenda-se que futuros estudos procurem relacionar a distribuição ambiental das peixarias à aquisição e ao consumo de pescados em Florianópolis.

Objective: To evaluate the association of a combined measure of availability and use of facilities from the food environment and overweight (including obesity) among schoolchildren, while taking into account the physical activity and social-assistance environments. Methods: Cross-sectional study with a probabilistic sample of schoolchildren aged 7 to 14 years living in a southern Brazilian city (n = 2026). Multilevel analyses were performed with overweight as outcome and the food environment as main exposure. Models were adjusted for the physical activity and social-assistance environments, as well as individual and other residential neighborhood characteristics. Results: Greater availability of restaurants around the home was associated with higher odds of overweight (odds ratio [OR] = 1.40; 95% CI = 1.06-1.85). Stronger associations were found for schoolchildren reporting to use restaurants (OR = 1.48; 95% CI = 1.15-1.90). This association remained significant after adjusting for the presence of other food retailers. Schoolchildren who had social-assistance facilities around their homes, but reported not to use them, showed consistently higher odds of being overweight (OR = 1.34; 95% CI = 1.01-1.78) as compared to schoolchildren who had these facilities near home and used them. The physical activity environment was not associated with the outcome. Conclusions: Availability and use of the food and social-assistance environments were significantly associated with overweight (including obesity) among the schoolchildren. Future research should consider the use of environmental facilities in combination to their geographical availability. Our results highlight the need for policies that limit the access to obesogenic food outlets by children and adolescents.
