摘　　要：目的评估南京市大气PM_(2.5)污染控制对循环系统疾病的健康收益。方法收集2013―2020年南京市环境空气质量、气象、死因监测数据,采用时间序列分析方法分析南京市大气PM_(2.5)对居民循环系统疾病(心血管疾病、脑血管疾病)死亡的暴露-反应关系系数,根据整合风险模型评估归因于南京市大气PM_(2.5)暴露导致循环系统疾病(心血管疾病、脑血管疾病)死亡人数。结果2013―2020年,南京市大气PM_(2.5)年均浓度从77.05μg/m^(3)降低到31.65μg/m^(3),下降幅度达58.92%;空气质量优良比例由54.25%升高到85.25%;大气PM_(2.5)浓度每升高10μg/m^(3),人群循环系统疾病死亡风险升高0.30%(95%CI:0.04%~0.56%);人群心血管疾病死亡风险升高0.44%(95%CI:0.07%~0.81%);人群脑血管疾病死亡风险升高0.30%(95%CI:0.00%~0.59%);循环系统疾病、心血管疾病、脑血管疾病归因死亡人数分别降低55.21%、58.33%、52.66%。结论2013―2020年,南京市大气PM_(2.5)浓度明显下降,循环系统疾病归因死亡人数显著减少,PM_(2.5)污染控制的健康收益显著。Objective To evaluate the health benefits of atmospheric PM_(_(2.5)) pollution control on circulatory system diseases in Nanjing.Methods The monitoring data of ambient air quality,meteorology,and cause of death in Nanjing from 2013 to 2020 were collected.Time series analysis was performed to explore the exposure-response relationship between the atmospheric PM_(_(2.5)) and circulatory system diseases mortality(cardiovascular diseases and cerebrovascular diseases)in Nanjing.The number of deaths attributed to circulatory diseases caused by atmospheric PM_(_(2.5)) exposure in Nanjing was evaluated according to the integrated risk model.Results From 2013 to 2020,the average annual atmospheric PM_(_(2.5)) concentration in Nanjing decreased from 77.05μg/m^(3) to 31.65μg/m^(3),with a decrease of 58.92%.The proportion of good air quality increased from 54.25%to 85.25%.Every 10μg/m^(3) increase in atmospheric PM_(_(2.5)) concentration increased the risk of death from circulatory diseases by 0.3%(95%CI:0.04%-0.56%).The risk of death from cardiovascular disease in the population increased by 0.44%(95%CI:0.07%-0.81%),and the risk of death from cerebrovascular disease increased by 0.30%(95%CI:0.009%-0.59%).The number of deaths attributable to circulatory,cardiovascular,and cerebrovascular diseases decreased by 55.21%,58.33%,and 52.66%,respectively.Conclusion From 2013 to 2020,the concentration of atmospheric PM_(_(2.5)) in Nanjing decreased significantly,the number of deaths attributed to circulatory diseases decreased significantly,indicating significant health benefits of PM_(_(2.5)) pollution control.
