Abstract
Background:
Systemic Arterial Hypertension (SAH) represents the most relevant worsening factor and one of the major risk factors for cardiovascular diseases.
Objectives:
To analyze trends in the mortality rate associated with hypertensive diseases in Brazil from 2010 to 2014, for states as well as regions.
Methods:
An epidemiological study was performed from aggregate data obtained in populational strata. Cartographic data of the Brazilian territory in “shapefile” were provided by IBGE. Records of mortality associated with arterial hypertension were obtained in DATASUS, through notifications filtered by category I.10 of the International Classification of Diseases (ICD-10). The criterion of statistical significance was a two-tailed p-value < 0.05.
Results:
The increase in age was progressively associated with an increase in the mean number of deaths related to hypertensive diseases between the years 2010 and 2014. In the age groups between 50-59 years, 60-69 years, 70-79 years and 80 or more years, the mean and standard deviation for the mortality rate were, respectively: 15.11% (35.35); 24.14% (55.34); 35.07% (81.03) and 57.87% (139.08). The overall mortality rate per 10,000 inhabitants varied between the regions: north (1.25); northeast (2.69); center-west (2.06); southeast (2.48) and south (2.04).
Conclusions:
The mortality rate associated with hypertensive diseases was higher in the southeastern and northeastern states of Brazil, and remained stable between 2010 and 2014. Increased age and brown color were predictors of higher mortality.
