The aim of this study was to present the prevalence of stroke from a pilot study in old people. The urban site sample (Madrid) was made up of 397 subjects and the rural site sample (Arévalo, Avila) of 862 subjects. The study was performed with a door-to-door methodology. In the urban sample, the prevalence of stroke was 8.5% (CI 95% = 5.5-11.5%) and that of TIA was 2.1% (CI 95% = 0.6-3.6%). In the rural location the prevalence of stroke was 7.1% (CI 95% = 5.4-8.8%). This prevalence of stroke is higher than in other Spanish studies. These results need to be confirmed in a wider investigation.
本研究的目的是通过一项针对老年人的试点研究呈现中风的患病率。城市样本（马德里）由397名受试者组成，农村样本（阿雷瓦洛，阿维拉）由862名受试者组成。该研究采用逐户访问的方法进行。在城市样本中，中风的患病率为8.5%（95%置信区间=5.5-11.5%），短暂性脑缺血发作（TIA）的患病率为2.1%（95%置信区间=0.6-3.6%）。在农村地区，中风的患病率为7.1%（95%置信区间=5.4-8.8%）。这种中风患病率高于西班牙的其他研究。这些结果需要在更广泛的调查中得到证实。
