  • - This study examined how different criteria of physical activity (CoPs) affect the classification of active preschoolers, analyzing data from 134 children aged 3-5 using a tri-axial accelerometer over seven days.
  • - The Pate CoP classified the highest percentage of children as active on both weekdays (73.9%) and weekends (85.6%), while the Johansson CoP labeled all participants as inactive.
  • - There was a notable gender difference in activity levels, with more boys being classified as active compared to girls, and overall activity rates were lower on weekends, particularly among females. The choice of CoPs significantly impacted the results.

Article Synopsis
  • The study aimed to explore the link between eating school meals from the National School Feeding Program and the dietary habits of Brazilian adolescents aged 13 to 17.
  • Using data from a large national survey, researchers identified three main dietary patterns: "unhealthy," "healthy," and "monotonous."
  • Results indicated that students who regularly consumed school meals were more likely to have healthier eating habits, suggesting that these meals can play a positive role in adolescent nutrition.

The aim of the current ecological study is to assess the evolution of food deserts and food swamps in the metropolitan city of Belo Horizonte between 2008 and 2020. Food deserts were determined based on the density of healthy establishments per 10,000 inhabitants, whereas food swamps were set based on the density of ultra-processed food procurement establishments per 10,000 inhabitants. The rate of census tracts classified as food deserts has decreased between 2008 and 2020, whereas that of census tracts classified as food swamps has increased within this same period.

Article Synopsis
  • - The study mapped food deserts and swamps in Recife, classifying areas based on the density of healthy versus unhealthy food retailers, using 2019 government data and 2010 census information.
  • - Food deserts, which make up 28.5% of areas studied, showed higher vulnerability with lower income, access to services, more illiteracy, and higher populations of minorities, while food swamps (73.47%) were found in neighborhoods with better socioeconomic conditions.
  • - The findings highlight social inequalities in food access, suggesting that public initiatives and potential taxation policies could help improve dietary habits in food deserts by promoting healthier food options.

Objective: To map the scientific research on food environments in Brazil, based on the following questions: How many studies have addressed food environments?; What study designs and methodological approaches were applied?; What is the geographic scope of the studies?; What scenarios and dimensions of food environments were studied?; Which population groups were studied?; How were food environments conceptualised?; What are the main limitations of the studies?

Design: Scoping review conducted in four databases, from January 2005 to December 2022, using different food environment-related terms to cover the main types and dimensions proposed in the literature. The studies were independently selected by two authors. A narrative synthesis was used to summarise the findings.

Background: Previous research suggests that unhealthy community food environments around schools contribute to unhealthy eating habits and negative health outcomes among the youth. However, little is known about how socioeconomic inequalities in those community food environments are associated with food deserts and food swamps across schools' neighborhoods.

Methods: An ecological study was carried out in all 3,159 public and private schools in Rio de Janeiro, Brazil.
