Overweight prevalence in Brazil by age 2023

When asked about their weight and height to estimate their body mass index (BMI), a study found that around 37.4 percent of Brazilian adults between 18 and 24 years were overweight (BMI≥25kg/m2) in 2023, a share below the national average. However, overweight was more prevalent among those aged 45 to 54 years in Brazil, with an overweight prevalence of more than 70 percent during that year.
