Evolution of Cardiovascular Diseases Mortality in the Counties of the State of Rio de Janeiro from 1979 to 2010.

Soares GP, Klein CH, Silva NA, Oliveira GM - Arq. Bras. Cardiol. (2015)

Bottom Line: There was a significant reduction in mortality rates across the three disease groups over the the three defined periods in all the county clusters analysed, Despite an initial mortality rate variation among the counties, it was observed a homogenization of such rates at the final period (2000-2010).This reduction cannot be explained by greater access to high technology procedures or better control of cardiovascular risk factors as these facts have not occurred or happened in low proportion of cases with the exception of smoking which has decreased significantly.Therefore, it is necessary to seek explanations for this decrease, which may be related to improvements in the socioeconomic conditions of the population.

ABSTRACT

Background: Cardiovascular Diseases (CVD) are the leading cause of death in Brazil.

Objective: To estimate total CVD, cerebrovascular disease (CBVD), and ischemic heart disease (IHD) mortality rates in adults in the counties of the state of Rio de Janeiro (SRJ), from 1979 to 2010.

Methods: The counties of the SRJ were analysed according to their denominations stablished by the geopolitical structure of 1950, Each new county that have since been created, splitting from their original county, was grouped according to their former origin. Population Data were obtained from the Brazilian Institute of Geography and Statistics (IBGE), and data on deaths were obtained from DataSus/MS. Mean CVD, CBVD, and IHD mortality rates were estimated, compensated for deaths from ill-defined causes, and adjusted for age and sex using the direct method for three periods: 1979-1989, 1990-1999, and 2000-2010, Such results were spatially represented in maps. Tables were also constructed showing the mortality rates for each disease and year period.

Results: There was a significant reduction in mortality rates across the three disease groups over the the three defined periods in all the county clusters analysed, Despite an initial mortality rate variation among the counties, it was observed a homogenization of such rates at the final period (2000-2010). The drop in CBVD mortality was greater than that in IHD mortality.

Conclusion: Mortality due to CVD has steadily decreased in the SRJ in the last three decades. This reduction cannot be explained by greater access to high technology procedures or better control of cardiovascular risk factors as these facts have not occurred or happened in low proportion of cases with the exception of smoking which has decreased significantly. Therefore, it is necessary to seek explanations for this decrease, which may be related to improvements in the socioeconomic conditions of the population.

f01: Mean CVD mortality rates per 100,000 inhabitants, compensated and adjusted by sexand age, in the counties of the state of Rio de Janeiro in three periods, from1979 to 2010.

Mentions: We noted that the mean CVD mortality rates (Figure1 and Table 1) decreased graduallyover the three periods analysed. In the first period, from 1979 to 1989, all but threeof the county clusters had mean CVD mortality rates above 500 deaths per 100,000inhabitants, while 13 had rates of more than 700 deaths per 100,000 inhabitants. Theserates decreased gradually until the last period, when all the county clusters had ratesof between 200 and 500 deaths per 100,000 inhabitants due to CVD. The mean CVD mortalityrate in the state was 347.1 deaths per 100.000 inhabitants in the most recent period,compared to 656.8 deaths per 100.000 inhabitants in the earliest period. Besides thegradual decrease in cardiovascular mortality, we also noted a tendency towardshomogenization of mortality rates among the county clusters and regions over time, whichcan be observed in the maps, and in the reduction of standard deviations (Figure 1 and Table1).
