Community food environment and childhood obesity in a medium‐sized Brazilian city: An approach to school and neighborhood environments

Abstract

AbstractObjectiveWe aimed to analyze the relationship of community food environments with childhood obesity in a medium‐sized Brazilian city.MethodsThis is a cross‐sectional study with 366 schoolchildren aged 8 and 9 years. Children's body mass index (BMI), waist circumference and concentrations of total cholesterol (TC), high cholesterol density lipoprotein (HDL‐c), low cholesterol density lipoprotein (LDL‐c) and triglycerides (TG) were measured. The parent's nutritional status was assessed by calculating the BMI. All food stores within a 200‐ and 400‐m radius buffers of schools and households were evaluated. The food stores were classified as healthy, unhealthy, and mixed according to the predominance of foods commercialized. Binary logistic regression models were proposed for each category.ResultsOver seventy percent (70.2%) of the food stores were categorized as “unhealthy”. The prevalence of obesity was 15.6%. In the 200‐m buffer around schools, there was an inverse and direct association between obesity and the presence of healthy food stores and unhealthy food stores, respectively. Around the households, there was an inverse association between the presence of healthy food stores and obesity in both buffers.ConclusionThe community food environment may be protective or potentiating childhood obesity, depending on the access and types of food sold.
