2015年太原市空气污染与医院门诊量关系的病例交叉研究
|
摘要
目的探讨2015年太原市煤烟型空气污染对医院呼吸系统、循环系统疾病门诊量的影响。方法采用病例交叉研究的方法,分析每日空气污染与1家市级医院2015年1~12月每日门诊量的相关性。结果太原市空气污染对呼吸系统疾病门诊量的影响发生较早,当天的影响最强,PM_(2.5)日均浓度每升高10μg/m~3,对呼吸系统疾病门诊量影响的OR为1.009 1;而对循环系统疾病门诊量的影响发生略晚1~2d,滞后1~2d的影响最强,OR为1.014 7。结论太原市空气污染对呼吸系统疾病门诊的影响要早于循环系统疾病,但对循环系统疾病门诊影响的危险强度要高于呼吸系统疾病门诊。
Objective To explore the effect of ambient air pollution on daily outpatient visits due to respiratory and circulatory diseases in Taiyuan city where the air pollution was mainly related to coal burning. Methods A case-crossover design was used to evaluate the relationship between air pollution and daily outpatient visits in Taiyuan city during January2015-December 2015. Results The effect of air pollution on respiratory diseases(lag0)was earlier than the effect on the circulatory diseases(lag1-lag2),the ORfor the effect on respiratory diseases was 1.009 1per 10μg/m~3 increment of PM2.5,while the ORfor the effect on circulatory diseases was 1.014 7per 10μg/m~3 increment of PM_(2.5). ConclusionThe air pollution in Taiyuan city has earlier effect on respiratory diseases compared with the effect on circulatory diseases,while the latter is stronger.
