Background: Brazil has one of the highest cerebrovascular death rates in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes.
Methods: We analyzed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by sex and age (35–74 y). The annual percent change (APC) and significant changes in the trends were identified with Poisson. The average annual percent change (AAPC) for 2005-09 was presented because that period had the best quality of information.
Results: After excluding deaths due to sequel from stroke, for men, the APCs (95% confidence intervals) were: 1979-84: 0.7 (-0.8 to 2.1); 1984-94: -1.8 (-2.4 to -1.2); 1994-07: -5.0 (-5.4 to -4.7); and 2007-09: -0.8 (-7.0 to 5.8). For women, the APCs were: 1979-94: -1.9 (-2.2 to -1.6); 1994-97: -7.5 (-14.0 to -0.6); 1997-07: -4.0 (-4.6 to -3.3); and 2007-09; 1.6 (-5.5 to 9.2). For the 2006-09 period, the AAPC (95% confidence interval) for all strokes was -3.1 (-3.3 to-2.9) for men and -2.9 (-3.1 to -2.8) for women. However, the AAPCs were not statistically significant for men aged 55-64 years or for women aged 45-64 years. For the same period, the AAPC of death rates for stroke subtypes were, for men and women, respectively: subarachnoid hemorrhage deaths: -1.4 (-2.5 to-0.2) and -3.2 (-5.7 to-0.6); intracerebral hemorrhage:-4.0 (-4.9 to-3.1) and 2.9 (-3.4 to-2.3); and ischemic stroke: -3.2 (-3.3 to-3.0) and -1.4 (-2.0 to -0.9).
Conclusion: Stroke mortality rates are declining in Brazil for all stroke subtypes.
