京津冀及周边地区归因于臭氧的慢性阻塞性肺部疾病疾病负担评估

Disease burden of COPD caused by ozone in Beijing-Tianjin-Hebei region

目的探讨臭氧长期暴露对京津冀及周边(简称京津冀,包括北京、天津、河北、山东、河南和山西)地区人群慢性阻塞性肺部疾病(COPD)影响,展开区县尺度的疾病负担评估。方法使用京津冀地区2013年臭氧暴露网格数据(空间分辨率:0.1°×0.1°),采用全球疾病负担评估方法,评估臭氧导致COPD超额死亡数和寿命损失年。结果京津冀地区臭氧浓度为64.39 ppb(约126.20μg/m^3),因长期臭氧暴露导致COPD死亡的超额死亡数约1.48万人,寿命损失年约66.38万年;臭氧致男性COPD疾病负担大于女性;不同省份的臭氧致COPD疾病负担顺位为河南>山东>山西>河北>天津>北京市。结论臭氧相关的COPD疾病负担较为严重,应控制臭氧前体物的排放,并加大对脆弱人群和重点地区的健康防护。

Objective To determine the chronic health effects of ozone exposure on the population,this study carried out a district and county scale disease burden assessment on chronic obstructive pulmonary disease(COPD)in Beijing-Tianjin-Hebei region,short for Beijing,Tianjin,Hebei and the surrounding areas(Shandong,He’nan and Shanxi).Methods The grid data of ozone exposure in Beijing-Tianjin-Hebei region in 2013(spatial resolution:0.1°×0.1°)and the method of global disease burden assessment were used to evaluate the excess deaths and life lost years of COPD caused by ozone in this area.Results The annual exposure concentration of ozone was 64.39 ppb(about 126.20μg/m^3)in Beijing-Tianjin-Hebei region.The excess deaths of COPD caused by long-term ozone exposure was about 14.8 thousand,and the years of life lost were about 663.8 thousand.The disease burden of COPD induced by ozone was higher in male compared with female.The analysis of the disease burden of COPD induced by ozone in different provinces showed order ranked as He’nan>Shandong>Shanxi>Hebei>Tianjin>Beijing.Conclusion The disease burden of COPD induced by ozone is more serious,and the emission of ozone precursors should be under control,and the health protection for vulnerable people in key areas should be enhanced.
