[Spatial evolution of cardiovascular mortality in Paraná State, Brazil: 1989-1991 and 2006-2008].

Abstract

This ecological study aimed to describe the spatial distribution of cardiovascular mortality in Paraná State, Brazil (1989-1991 and 2006-2008) and its correlation with socioeconomic variables, using mortality data from the DATASUS database and population data from IBGE. Mortality rates were adjusted by the local empirical Bayesian method. Correlation analysis used the Moran I index and Spearman coefficient. There were no significant correlations or spatial dependence between mortality and socioeconomic variables. Mortality was higher in males in both periods. Cardiovascular mortality declined from 1989-1991 to 2006-2008 and was higher in females. Construction of thematic maps allowed visualization of the regions with highest cardiovascular risk. The decrease in mortality can be partially explained by expanded access to health services and improved living conditions and income.
