[All-cause and cardiovascular diseases mortality in three Brazilian states, 1980 to 2006].

OBJECTIVE

to evaluate mortality from all causes, diseases of the circulatory system (DCS), ischemic heart disease (IHD), and cerebrovascular diseases (CVD) from 1980 to 2006 in Rio de Janeiro, Rio Grande do Sul, São Paulo, and their capitals, taking into consideration the impact of deaths due to ill-defined causes.

METHODS

population and mortality data were obtained from the Unified Health System's Data Bank (DATASUS). Mortality from the diseases of interest and from ill-defined causes was adjusted by the direct method for adults older than 20 years of age. Since the mortality rates from ill-defined causes increased markedly after 1990, proportional mortality rates from ill-defined causes were calculated. Linear regression models were used for analysis of trends.

RESULTS

a relevant decline in all-cause mortality was observed in the three states and capitals. Rio de Janeiro and its capital had the highest rates of all-cause mortality. DCS mortality declined more than all-cause mortality. Proportional mortality from ill-defined causes in Rio de Janeiro and its capital was higher than in all other states and capitals starting in 1990. CVD mortality fell in the study period, especially in Rio de Janeiro and its capital. The state of Rio de Janeiro also had the highest IHD mortality rates until 1993. Among the capitals, São Paulo presented the highest IHD mortality rates starting in 1992.

CONCLUSIONS

the decline in all-cause mortality resulted mainly from the decline in DCS mortality. In turn, the decline in DCS mortality was partly due to the reduction in CVD mortality, especially in the state of Rio de Janeiro.
