背景和目的：我们描述了30年来巴西脑卒中死亡率的趋势，并根据地区差异、性别和年龄分布调查了它们的差异。方法：检索有关死亡率和人口估计数的官方数据，以计算1980年、1990年和2000年最初阶段（头三年）6个年龄层和5个政治区域的标准化死亡率（以1980年巴西人口为参照）。对未定义的死亡原因进行了校正。泊松模型用于估计30年间的风险降低，并研究这些比率与性别、年龄层和地区之间的相互作用。结果：近20年来，脑卒中标准化死亡率持续下降，从68.2 / 10万降至40.9 / 10万。与此同时，心血管疾病总死亡率也在同期下降，从每10万居民208.2人降至126.1人。卒中标准化死亡率在男性和女性以及所有年龄层中均有所降低。这一减少在该国所有地缘政治区域都很明显，最富裕区域的初始死亡率较高，标准化死亡率下降更明显。2000年至2002年期间死于中风的风险是1980年至1982年期间的0.45 （95% Cl， 0.44至0.45）。结论：从20世纪80年代初到21世纪初，巴西死于中风的风险急剧下降。这种下降在最发达区域尤为明显，这可能反映了在研究期间总体健康状况的改善。
Background and Purpose-We describe the trends in stroke mortality in Brazil during 3 decades and investigate their differences according to regional disparities, sex, and age distributions.Methods-Official data on mortality and population estimates were retrieved to calculate standardized mortality rates (with the 1980 Brazilian population as a reference) in 6 age strata and in the 5 political regions for the initial period (3 first years) of the 1980, 1990, and 2000 decades. Data were corrected for undefined causes of death. The Poisson model was used to estimate risk reduction during, the 3 decades and to study the interaction between those rates and sex, age strata, and regions.Results-The stroke standardized mortality rate decreased consistently in the last 20 years, from 68.2 to 40.9 per 100 000 habitants. This reduction paralleled a decrease in total cardiovascular mortality rates in the same period, from 208.2 to 126.1 per 100 000 habitants. The reduction in stroke standardized mortality rate was detected in men and women and in all age strata. The reduction was evident in all geopolitical regions of the country, with the wealthiest regions' exhibiting higher initial rates and more marked standardized mortality rate reductions. The risk of dying of stroke in the period 2000 to 2002 was 0.45 (95% Cl, 0.44 to 0.45) of that found in the period 1980 to 1982.Conclusions-The risk of dying of stroke in Brazil declined dramatically between the initial period in the early 1980s and the early 2000s. The decline was especially marked in the most developed regions and may reflect an improvement in General health conditions during the study period.
