摘　　要：目的 采用Meta分析方法评价近年来国内外大气细颗粒物（PM2.5）暴露对人群每日死亡率的影响。方法 检索Pub Med和Web of Science数据库,收集并筛选所有近年来PM2.5暴露与人群死亡关系的文献资料,并对文献中相关的数据信息进行提取,通过Meta分析对近年来亚洲、北美洲和欧洲3个地区的PM2.5暴露与每日死亡率的关系进行分析评价。结果经过分析得出亚洲地区、北美地区和欧洲地区的PM2.5的浓度每升高10μg/m^3,居民死亡率百分比分别增加0.96%（95%CI：0.94%-0.97%）、1.05%（95%CI：1.03%-1.08%）和1.80%（95%CI：1.23%-2.36%）。结论 不同地区PM2.5浓度升高后居民死亡率均有所升高,但亚洲地区的死亡率增幅低于欧洲、北美地区。Objective By adopting the method of Meta analysis to evaluate the association between PM2. 5 exposure and daily mortality rates at home and abroad in recent years. Methods Publications regarding the mortality rate of PM2. 5 in recent years were extracted from PubMed, Web of Science. Relevant information was extracted and data was analyzed using random - effects model. Meta - analysis was used to analyze the relationship of PM2. 5 exposure and daily mortality of Asia, North America and Europe in recent years. Results According to the analysis, we observed a 0. 96% （95% Cl： 0. 94% ？0. 97% ） increase in all - cause mortality in Asia, a 1.05% （95% Cl： 1. 03% ~ 1. 08% ） increase in North America and a 1. 80% （95% Cl： 1. 23% - 2. 36% ） increase in Europe with every 10μLg/m^3 increase of PM2. 5. Conclusion With the increase of the concentration of PM2. 5 , the mortality of different regions all increased, however, the mortality of Asia showed a lower degree than that in Europe and North America.
