0265/2024 - Mortalidade por câncer de mama feminino atribuível ao sobrepeso e obesidade no Brasil Mortalityfemale breast cancer attributable to overweight and obesity in Brazil
Este estudo objetivou avaliar a mortalidade por câncer de mama feminino atribuível ao sobrepeso e obesidade e estimar o número de mortes evitáveis com a redução do Índice de Massa Corporal no Brasil. Realizou-se um estudo ecológico com investigação das informações de sobrepeso, obesidade, características sociodemográficas a partir de pesquisa nacional realizada em 2013-14; taxa de mortalidade por câncer de mama em 2019, utilizando o Atlas online de mortalidade e Riscos Relativos de meta-análises. Realizou-se a análise da Potential Impact Fraction, considerando os seguintes cenários contrafactuais relacionados a redução do IMC: Cenário A - contingente populacional das mulheres que compõe as prevalências de sobrepeso e obesidade passa a compor a prevalência de eutrofia; Cenário B - contingente populacional das mulheres que compõe a prevalência de sobrepeso passa a compor a prevalência de eutrofia; Cenário C - contingente populacional das mulheres que compõe a prevalência de obesidade passa a compor a prevalência de sobrepeso. No Brasil eliminando o sobrepeso e a obesidade entre mulheres (? 50 anos), 2.022 (PIF–14,3%) mortes por câncer de mama seriam evitadas. A redução do sobrepeso e obesidade impactariam na diminuição da mortalidade por câncer de mama no Brasil.

Abstract:
This study aimed to evaluate mortalityfemale breast cancer attributable to overweight and obesity and to estimate the number of preventable deaths with a reduction in the Body Mass Index in Brazil. An ecological study was carried out with investigation of information on overweight, obesity, sociodemographic characteristics based on a national survey carried out in 2013-14; breast cancer mortality rate in 2019 using the Online Atlas of Mortality and Relative Risks Meta-Analyses. The Potential Impact Fraction analysis was carried out, considering the following counterfactual scenarios related to the reduction in BMI: Scenario A - population contingent of women that make up the prevalence of overweight and obesity now composes the prevalence of eutrophy; Scenario B - population contingent of women that make up the prevalence of overweight starts to make up the prevalence of eutrophy; Scenario C - population contingent of women that make up the prevalence of obesity becomes part of the prevalence of overweight. In Brazil, eliminating overweight and obesity among women (≥ 50 years), 2,022 (PIF–14.3%) deathsbreast cancer would be prevented. The reduction of overweight and obesity would impact on the reduction of breast cancer mortality in Brazil.
