[目的]探讨我国PM_(2.5)污染与呼吸系统疾病门诊量的关系。[方法]使用计算机联机检索国内外数据库,搜集PM_(2.5)浓度变化与呼吸系统疾病门诊量关系有关资料,使用Stata 12.0软件进行Meta分析。[结果]共纳入文献12篇,13组数据,涉及我国8个地区。PM_(2.5)5质量浓度每升高10μg/m~3,呼吸系统疾病门诊量的RR为1.005(95%CI:1.003~1.007),经敏感性分析剔除异常值后,RR值为1.005(95%CI:1.003~1.008),其中成人呼吸系统疾病门诊量RR为1.004(95%CI:1.000~1.007)、儿童为1.008(95%CI:1.003~1.013);中国北方地区门诊量RR值为1.006(95%CI:1.002~1.009)、南方地区RR值为1.004(95%CI:1.000~1.009);呼吸系统疾病门诊量RR值为1.005(95%CI:1.001~1.008)、哮喘为1.008(95%CI:1.003~1.013)、呼吸道感染为1.001(95%CI:0.997~1.004)。经漏斗图、Egger检验无发表偏倚。[结论]PM_(2.5)污染与呼吸系统疾病门诊量具有一定的相关性,随着大气中PM_(2.5)质量浓度的上升,呼吸系统疾病门诊量增加。
[Objective] To explore the relationship between the PM_ (2.5) pollution and outpatient respiratory disease in China. [Methods] Using computer to search domestic and foreign databases online, and to collect the data about the relationship between the change of concentration of PM 2.5 and outpatient volume of respiratory diseases. Stata 12.0 software was used for Meta analysis. [Results] A total of 12 articles and 13 sets of data were collected, covering 8 regions in China. The RR of outpatients with respiratory diseases was 1.005 (95% CI: 1.003-1.007) for every 10 μg / m ~ (3) PM_ (2.5) 5 concentration increase and RR of 1.005 % CI: 1.003-1.008). Among them, the outpatient RR of adult respiratory diseases was 1.004 (95% CI: 1.000-1.007) and 1.008 (95% CI: 1.003-1.013) in children. The RR of outpatients in northern China was 1.006 (95% CI: 1.002-1.009). The RR in the south was 1.004 (95% CI: 1.000-1.009). The outpatient RR was 1.005 (95% CI: 1.001-1.008) and 1.008 % CI: 1.003 ~ 1.013) and respiratory tract infection was 1.001 (95% CI: 0.997-1.004). After funnel plot, Egger’s test showed no publication bias. [Conclusion] There is a certain correlation between the PM 2.5 pollution and the outpatient volume of respiratory diseases. As the concentration of PM 2.5 in the atmosphere increases, the outpatient amount of respiratory diseases increases.
