Sources of food ready to consume around the Health Academy Program units: an analysis according to inequality.

The aim of this study was to spatially examine the distribution of establishments for the acquisition of food that is ready to consume around the Health Academy Program (PAS) in Belo Horizonte, Minas Gerais, Brazil, according to the Municipal Human Development Index (IDH-M).This is an ecological study with the PAS as the unit of analysis.

The COVID-19 pandemic in a Brazilian metropolis: repercussion on food prices.

We analyzed the impact of the efforts to combat the COVID-19 pandemic on the prices of food sold by a food supply center located in the sixth largest city in Brazil. We examined the percentage change in the prices of 20 types of foods, adjusted by market conditions, using municipal contingency plan stages to compare opening and closing of non-essential services, including bars and restaurants (stage 1: first phase of essential services-only; stage 2: flexibilization; and stage 3: second phase of essential services-only with a "pre-pandemic" period [stage 0]). Log-prices were lower in all contingency stages for leafy greens (variation: 42% to 56%) and vegetables (variation: 28% to 40%).

Is the management of obesity in primary health care appropriate in Brazil?

This study aims to describe the adequacy of basic health units (UBS) in Brazil regarding structure and work process for obesity management and to evaluate user satisfaction with primary health care services. This cross-sectional study was conducted with data from the 2013-2014 National Program for Improving Primary Care Access and Quality (PMAQ) - an initiative to assess primary health care teams' performance. Data were collected between 2013 and 2014 through interviews with primary health care teams and users.

Objective: to validate self-reported body weight of Programa Academia da Saúde (PAS) users in Belo Horizonte, MG, Brazil, and to identify factors associated with weight error.

Methods: self-reported body weight, obtained by telephone interview, was compared to measured weight; we used Student's t-test, ANOVA, Lin's concordance correlation coefficient, the Bland-Altman method and Kappa coefficient; women's self-reported weight was corrected according to measured weight using multiple regression.

Results: 441 users participated; weight self-reported by men was valid (error=0; p=0.
