Abstract
Introduction
Despite the preventive actions, breast cancer (BC) in Brazil has a high mortality, probably due to the identification of the tumor in advanced stages.
Objective
To analyze mortality from BC in the health micro-regions of Minas Gerais (MG), 2013-2017, and its possible association with social inequality.
Method
Ecological study, whose unit of analysis was the health micro-regions of MG. Mortality, sociodemographic and health data were extracted from SIM, IBGE, PROADESS, and DATASUS. Specific and age-standardized mortality rates were calculated, thematic maps were constructed, and statistical analyzes were performed using the Moran Index and multiple simple regression.
Results
From 2013-2017 there were 7,571 deaths from BC in MG. The deadliest microregions are in the Center and East; the smallest in the North and Northeast. Most variables had a high coefficient of variation and were significant in the simple linear regression model. In the multiple distal and proximal models, only the degree of urbanization was significant. All variables showed significant spatial autocorrelation and spatial dependence.
Conclusion
High mortality rates in the most urbanized micro-regions can be explained by reproductive, behavioral factors and the distribution of health resources, present in large urban centers.
