脑血管病是严重危害老年人健康长寿的一组疾病,是人类三大主要疾病死亡原因之一。随着我国人民群众生活水平的不断提高,对脑血管病的防治研究土作越显得重要和迫切。从80年代起,我国医学工作者就着手在全国进行了几次大规模的脑血管病的流行病学调查及病例对比分析的研究,取得了可喜的成绩,初步探索出一些和本病发病有关的病因学线索,为降低本病的发病率及死亡率提供了较为可靠的防治措施。我们从1983年1月1日至12月31日,在银川市老城区所属22个居委会的136 385人群中,按地理分布,采用分层整群随机抽样
Cerebrovascular disease is a group of diseases that seriously endanger the health and longevity of the elderly and is one of the three major causes of death in humans. With the continuous improvement of the living standards of the people in our country, the more important and urgent the research on the prevention and treatment of cerebrovascular disease is. Since the 1980s, Chinese medical workers have started to conduct several large-scale epidemiological investigations and case-contrast analyses of cerebrovascular disease across the country. Gratifying results have been obtained and preliminary explorations have been made concerning the incidence of this disease. The etiology clues provide relatively reliable prevention and treatment measures to reduce the incidence and mortality of this disease. From January 1, 1983 to December 31, 1983, we used stratified cluster random sampling in a population of 136 385 from 22 neighborhood committees in the old city of Yinchuan.
