    ABSTRACT

    This study analyzes how the rates of increase in Brazil differ by obesity class. The paper estimates time trends for extreme weight categories from 2006 to 2021 and extrapolates through 2025 using Vigitel. Comparing 2021 to 2006 rates, the prevalence of BMI≥45 increased by 152%, BMI≥40 by 120%, and BMI≥35 by 104%. In contrast, BMI≥30 increased by 66%. Results are adjusted for demographic changes. Severe obesity is increasing far more rapidly than what commonly reported obesity statistics indicate. These groups have higher health burdens and healthcare needs, and the health system needs to be prepared to see such individuals regularly.
