Abstract
INTRODUCTION: Excess weight is an important risk factor for increased morbidity and mortality in a population, being considered the second greatest cause of preventable death, second only to smoking. The objective of this article is to describe the historical series of overweight and obesity prevalence in Brazil between 2006 and 2023, both overall and stratified by sex, age groups and Federation Units. MATERIALS AND METHODS: The data sources used were all editions of the Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel). The analyzes were performed using the SAS on demand statistical program. RESULTS: Considering all the capitals studied, between 2010 and 2011 the proportion of individuals with excess weight became similar to the proportion of individuals with normal weight in Brazilian capitals and from 2012 it surpassed the proportion of individuals with normal weight. And finally, in the 2023 results for Brazil as a whole, for the first time the proportion of overweight individuals exceeded that of those with normal weight. CONCLUSIONS: This analysis of the historical series of the Vigitel survey shows a worrying scenario in Brazilian capitals with a progressive increase in the proportion of obesity and overweight and a decrease in normal weight, as well as the speed at which these proportions are changing over time. Although there are variations in each capital, the general scenario is similar.
