Among the causes of obesity, environmental factors have also been studied, in addition to genetic, social, psychological, and hormonal factors. The distribution of food outlets, facilitating or hindering food acquisition, can promote body weight control by encouraging healthier food habits. The objective of this study was to investigate associations between environmental availability and utilization of food outlets and overweight/obesity in 7 to 14-year-old schoolchildren in Florianopolis, in the South of Brazil. A logistic regression analysis identified a positive association between overweight/obesity in 2195 schoolchildren and the presence of restaurants in the vicinity of their homes (buffer = 400 meters). Being a member of a family that utilizes public markets/greengrocers was also positively associated with overweight/obesity in the sample investigated. Identifying the distribution of these establishments in the vicinity of the homes of schoolchildren in middle-income countries is an important element in understanding the role played by the food environment in weight gain in a variety of different settings.
