背景和目的很少有研究考察空气污染逐小时变化对心血管疾病发病率的影响。我们评估了空气污染的小时变化与几种心血管疾病风险之间的关系。方法采用时间分层病例交叉设计。研究的参与者是日本冈山市的10949名65岁的居民，他们在2006年1月至2010年12月期间因心血管疾病发作而被送往医院急诊室。我们计算了来自几个监测站的具有城市代表性的空气污染物小时平均浓度，并检查了病例事件发生前空气污染暴露之间的关系，主要关注悬浮颗粒物与疾病发病之间的关系。结果悬浮颗粒物暴露量0 ~
Background and Purpose Few studies have examined the effect of hourly changes in air pollution on cardiovascular disease morbidity. We evaluated the associations between hourly changes in air pollution and the risks of several types of cardiovascular disease.Methods We used a time-stratified case-crossover design. Study participants were 10 949 residents of the city of Okayama, Japan, aged 65 years who were taken to hospital emergency rooms between January 2006 and December 2010 for onset of cardiovascular disease. We calculated city representative hourly average concentrations of air pollutants from several monitoring stations and examined the associations between air pollution exposure before the case event, focusing mainly on suspended particulate matter, and disease onset.Results Suspended particulate matter exposure 0 to
