摘要
目的了解大气总悬浮颗粒物(TSP)对心血管疾病的危害程度。方法采用生态学研究方法,运用Poisson回归分析沈阳市TSP与心血管疾病死亡率(1996～2000年)的联系。结果调整了时间、气象因素后,TSP每增加50μg/m3,总人群心血管疾病死亡率OR值为1.0122(95%CI=1.0036～1.0209),男性组为1.0278(95%CI=1.0160～1.0398),女性组为1.0406(95%CI=1.0294～1.0519),老年组(>65岁)为1.0430(95%CI=1.0343～1.0519),其中老年男性组为1.0577(95%CI=1.0452～1.0703),老年女性组为1.0427(95%CI=1.0284～1.0572)。结论大气中的TSP可能是导致心血管疾病死亡率变化的一个原因。
Objective To estimate the adverse effects of total suspended particles exposure on cardiovascular disease mortality.Methods Cardiovascular disease mortality and TSP monitoring data from1996to2000in Shenyang were collected.The association between TSP concentration and the mortality of cardiovascular diseases was analyzed using Poisson regression model adjusted for season,temperature and humidity variation using a parametric method.Results It was found that each50μg /m 3 increment of TSP was associated with an OR of1.0122(95%CI =1.0036-1.0209)of cardiovascular disease mortality in the general population,an OR of1.0278(95%CI =1.0160-1.0398)in the male group,1.0406(95%CI =1.0294-1.0519)in the female group,1.0430(95%CI =1.0343-1.0519)in the general aged group,1.0577(95%CI =1.0452-1.0703)in the aged male group and1.0427(95%CI =1.0284-1.0572)in the aged female group.Conclusion The results showed that there was an association between TSP concentration and the cardiovascular disease mortality in Shenyang.It was considered that TSP might be one of the risk factors related to the increase of cardiovascular disease mortality.
