| 目的 定量评估北京市昌平区空气中粒径≤ 2.5 μm的颗粒物（PM2.5）对居民心血管系统疾病累积超额死亡率（CER）及寿命损失年（YLL）的短期影响。方法 收集2014-2017年北京市昌平区户籍人群的死亡个案资料、PM2.5、二氧化硫（SO2）、二氧化氮（NO2）浓度资料及气象资料，运用分布滞后非线性模型，分析不同滞后天数PM2.5浓度对不同人群心血管系统疾病CER及YLL的影响。结果 PM2.5对心血管系统疾病CER和YLL的危害效应分别在滞后7 d和9 d时开始显现，滞后14 d时达到最大，持续时间长达21 d。累积滞后21 d时，PM2.5每增加10 μg/m3，人群心血管系统疾病死亡的CER为0.021%（95% CI：0.004%~0.038%），YLL为1.47（95% CI：0.23~2.70）年。PM2.5对男性及≥ 75岁人群心血管系统疾病死亡的CER和YLL影响更大。结论 PM2.5可以增加人群心血管系统疾病的死亡率和YLL。 |

| Objective To make a quantitative evaluation on the short term effect of particulate matter with aerodynamic diameter no more than 2.5 μm (PM2.5) on cumulative excess mortality rate (CER) and years of life lost (YLL) in residents in Changping district of Beijing. Methods The death data in local residents, daily mortality, meteorology data and air pollution data (PM2.5, SO2 and NO2 concentrations) in Changping from 2014 to 2017 were collected. Distributed lag non-linear model was used to assess the age and gender specific cumulative lag effects of PM2.5 on cardiovascular CER and daily YLL in Changping. Results The effects of PM2.5 on cardiovascular CER and YLL were obvious on lag 7 days and lag 9 days, respectively, peaking on day 14, and lasting for 21 days. On lag0-21 days, for a 10 μg/m3 increase in PM2.5, the population based CER of cardiovascular disease death was 0.021% (95% CI:0.004%-0.038%), and the YLL was 1.47 (95% CI:0.23-2.70) years. Greater PM2.5 effect were observed in males and the elderly. Conclusion PM2.5 increased the risk of cardiovascular disease death and YLL. |
