【摘要】：目的采用死亡数和寿命损失年(YLL)两种疾病负担指标,定量评估大气二氧化氮(NO_2)对人群健康效应的影响。方法收集天津市六个城区2001年1月1日至2010年12月31日的每日大气NO_2和死因监测数据,并计算每日YLL值,采用广义相加模型分别建立大气NO_2对暴露人群每日死亡及每日YLL影响的暴露反应关系,最后采用Meta分析方法对六城区的结果进行合并。结果除和平区外,天津市其他5个城区大气NO_2均可导致暴露人群非意外死亡数和YLL值的增加。天津市城区大气NO_2日均浓度(lag0~1)每升高10μg/m~3,可分别导致暴露人群每日死亡和每日YLL值增加0.67%(95%CI:0.40%~0.93%)和1.62(95%CI:0.69~2.54)人年。结论天津市城区大气NO_2可导致暴露人群死亡和YLL的增加,但不同的城区之间存在一定的差异。
[Abstract]:Objective to quantitatively evaluate the effect of atmospheric nitrogen dioxide (NO2) on population health by using two disease burden indexes: death rate and life lost year (YLL).Methods the data of daily atmospheric NO_2 and cause of death were collected from January 1, 2001 to December 31, 2010 in six urban areas of Tianjin, and the daily YLL values were calculated.The general additive model was used to establish the exposure response relationship of atmospheric NO_2 to the daily death and daily YLL of exposed population. Finally, the results of six urban areas were combined with Meta analysis method.Results with the exception of Heping District, the number of non-accidental deaths and the YLL value of exposed population were increased in five other urban areas of Tianjin.Conclusion Atmospheric NO_2 can lead to death and increase of YLL in urban area of Tianjin, but there are some differences among different urban areas.
