空气污染的程度和类型、不同的环境条件和健康之间的关系的研究结果各不相同.该研究探讨空气污染和急性心肌梗死(AMI)之间的关系. 方法每小时检测一次空气污染物(SO_2、NO_2和O_3)的浓度.自1985年开始,收集法国西南部所有AMI的登记数据.记录年龄在35～64岁的所有AMI、猝死、可能的心源性死亡病例.应用病例交叉设计方法,研究短期污染物暴露发生AMI的风险(从1997年1月1日至1999年6月30日).并对数据进行条件回归分析.
The results of studies on the extent and type of air pollution and the relationship between different environmental conditions and health vary. The study explored the relationship between air pollution and acute myocardial infarction (AMI). Methods Air pollutants ( SO_2, NO_2, and O_3), registration data for all AMIs in southwestern France have been collected since 1985. Sudden deaths and possible cardiac deaths were recorded for all AMIs between the ages of 35 and 64. Case-cross design was used , To study the risk of AMI exposure to short-term contaminants (from January 1, 1997 to June 30, 1999), and conditional regression analysis of the data.
