Trends in Stroke-Related Mortality in the ABC Region, S?o Paulo, Brazil: An Ecological Study Between 1997 and 2012

摘要

Background:Stroke is the second leading cause of death and the third leading cause of physical disability in the world, with a high burden of morbidity and mortality, but it has been shown a reduction in mortality worldwide over the past two decades, especially in regions with higher income.Objective:The study analyzed the temporal trend and the factors associated with stroke-related mortality in the cities that make up the ABC region of S?o Paulo (Santo André, S?o Bernardo do Campo, S?o Caetano do Sul, Diadema, Mauá, Ribeir?o Pires, and Rio Grande da Serra), in comparison to data from the capital city of S?o Paulo, in the state of S?o Paulo, Brazil.Method:This was an ecological study conducted in 2017 using data from 1997 to 2012. Data were collected in 2017 from the Department of Informatics of the Brazilian Unified National Health System (DATASUS), where the Mortality Information System (SIM/SUS) was accessed. Linear regression analysis was used to estimate the temporal trend of stroke-related mortality according to sex, stroke subtypes, and regions. The confidence level adopted was 95%.Results:There was a reduction in the mortality rates stratified according to sex, age groups above 15 years, and subtypes of stroke. Mortality from hemorrhagic and non-specified stroke decreased in all regions. However, a significant reduction in ischemic stroke-related mortality was observed only in the ABC region and in Brazil.Conclusion:The ABC region showed greater mortality due to stroke in males, the age group above 49 years, and non-specified stroke between 1997 and 2012.
