Brazil has one of the highest cerebrovascular death rates in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes.
We analyzed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by gender and age (35-74 years). The annual percent change and significant changes in the trends were identified with Poisson regression.
After excluding deaths due to sequel from stroke for men, the annual percent changes (95% confidence intervals) were as follows: 1979-1984, 0.7 (-0.8 to 2.1); 1984-1994, -1.8 (-2.4 to -1.2); 1994-2007, -5.0 (-5.4 to -4.7); and 2007-2009, -0.8 (-7.0 to 5.8). For women, the annual percent changes were as follows: 1979-1994, -1.9 (-2.2 to -1.6); 1994-1997, -7.5 (-14.0 to -0.6); 1997-2007, -4.0 (-4.6 to -3.3); and 2007-2009, 1.6 (-5.5 to 9.2). For the 2006-2009 period, the average annual percent change (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. For the same period, the average annual percent change of death rates for stroke subtypes were, for men and women, respectively: 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).
Stroke mortality rates are declining in Brazil for all stroke subtypes.
巴西是西半球脑血管死亡率最高的国家之一。我们调查了不同性别和卒中亚型的时间趋势。
我们分析了 1979 年至 2009 年不同卒中亚型的死亡率。数据按性别和年龄(35-74 岁)分层。采用泊松回归分析年度百分比变化和趋势的显著变化。
排除男性卒中后继发死亡后,每年的百分比变化(95%置信区间)如下:1979-1984 年为 0.7(-0.8 至 2.1);1984-1994 年为-1.8(-2.4 至-1.2);1994-2007 年为-5.0(-5.4 至-4.7);2007-2009 年为-0.8(-7.0 至 5.8)。对于女性,每年的百分比变化如下:1979-1994 年为-1.9(-2.2 至-1.6);1994-1997 年为-7.5(-14.0 至-0.6);1997-2007 年为-4.0(-4.6 至-3.3);2007-2009 年为 1.6(-5.5 至 9.2)。在 2006-2009 年期间,所有卒中的平均年百分比变化(95%置信区间)为男性为-3.1(-3.3 至-2.9),女性为-2.9(-3.1 至-2.8)。同期,男性和女性卒中亚型死亡率的平均年百分比变化分别为:脑出血为-4.0(-4.9 至-3.1)和-2.9(-3.4 至-2.3);缺血性卒中为-3.2(-3.3 至-3.0)和-1.4(-2.0 至-0.9)。
巴西所有卒中亚型的卒中死亡率都在下降。
