Abstract目的 综合相关文献并以暴露-反应关系的形式探讨中国可吸入颗粒物( PM10)污染对人群死亡率的影响.方法 收集符合纳入标准的中国大气颗粒物污染与居民总死亡率、心脑血管疾病死亡率、呼吸系统疾病死亡率关系的文献,共纳入21篇文献.采用Stata9.0软件进行统计分析,提取PM10与人群死亡率的暴露-反应系数,利用固定或随机效应模型合并效应值,并对结果进行敏感性分析、发表偏倚检验与校正.结果 我国大气PM10每上升10 μg/m3,人群每日总死亡率、心脑血管疾病和呼吸系统疾病死亡率的相对危险度(RR)分别为1.0033(95% CI:1.0022~1.0044)、1.0045(95% CI:1.0029 ~1.0062)和1.0056(95%CI:1.0033~1.0079);校正发表偏倚后,人群每日总死亡率、心脑血管疾病和呼吸系统疾病死亡率的RR值降为1.0012(95%CI:1.0002~1.0022)、1.0011(95% CI:0.9996~1.0026)和1.0023(95% CI:1.0001~1.0045).结论 大气中PM10浓度的上升会导致我国人群每日总死亡率、心脑血管疾病死亡率和呼吸系统疾病死亡率的增加.
Objective Synthesize the relevant research and then discuss the influence of inhalable particulate matter ( PM10 ) on mortality by exposure-response analysis.Methods The eligible research papers which studied the association between PM10 and overall mortality of residents,the mortality of cardiovascular and cerebrovascular diseases and the mortality of respiratory diseases; and 21 pieces of the papers were adopted in this study.The papers were analyzed by Stata 9.0 software,and the exposure-response coefficient of PM10 and mortality were extracted.The effect size was amalgamated by fixed or random effects,and the sensitivity analysis and publication bias of the results were detected and adjusted.Results Each 10 μg/m3 increase of PM10 was associated with estimated relative risk (RR) of daily all-course mortality,the mortality of cardiovascular and cerebrovascular diseases and the mortality of respiratory diseases at 1.0033 (95%CI:1.0022 - 1.0044),1.0045 (95%CI:1.0029 - 1.0062) and 1.0056(95%CI:1.0033 -1.0079),respectively.After the publication bias was adjusted,the RR of daily all-cause,cardiovascular and cerebrovascular diseases and respiratory diseases mortality was reduced to 1.0012 (95% CI:1.0002 -1.0022 ),1.0011 ( 95% CI:0.9996 - 1.0026 ) and 1.0023 ( 95% CI:1.0001 - 1.0045 ).Conclusion The increase of the concentration of PM10 led to the increase of the daily all-course mortality,the mortality of cardiovascular and cerebrovascular diseases and the mortality of respiratory diseases.
