摘要:
目的 评估空气污染对上海市某区医院门诊量的影响,为采取有效干预措施、保护公众健康提供科学依据。
方法 收集2013-2015年上海市气象和环保数据以及某区中心医院门诊总量、呼吸系统疾病和循环系统疾病日门诊量,对所收集数据进行时间序列分析。
结果 在总门诊中,污染物每升高10 μg/m3,PM2.5使门诊量增加0.26%、PM10为0.19%、二氧化硫(SO2)为2.70%、二氧化氮(NO2)为3.00%;在呼吸系统疾病中,污染物每升高10 μg/m3,PM2.5使门诊量增加0.73%、PM10为0.55%、SO2为4.00%、NO2为2.30%:在循环系统疾病中,污染物每升高10 μg/m3,PM2.5使门诊量增加0.17%、PM10为0.23%、SO2为2.80%、NO2为2.50%。
结论 大气污染物(PM2.5、PM10、NO2、SO2)浓度的升高会增加该区医院门诊的就诊量。
Abstract:Objective To evaluate the effects of air pollution on outpatient visits in a district of Shanghai and to provide a scientific basis for making effective intervention measures and protecting public health.
Methods Meteorological and environmental data of Shanghai and the total, respiratory system disease, and circulatory system disease outpatients of a district hospital in Shanghai from 2013-2015 were collected for a time-series analysis.
Results The increased total outpatients were 0.26%, 0.19%, 2.70%, and 3.00% respectively for an increase of 10 μg/m3 in PM2.5, PM10, sulfur dioxide (SO2), and nitrogen dioxide (NO2). For respiratory system disease outpatients, the increase induced by PM2.5 with the same increment was 0.73%, 0.55% by PM10, 4.00% by SO2, and 2.30% by NO2. For circulatory system disease outpatients, the increase induced by PM2.5 with the same increment was 0.17%, 0.23% by PM10, 2.80% by SO2, and 2.50% by NO2.
Conclusion Elevated concentrations of air pollutants such as PM2.5, PM10, NO2, and SO2 would associate with the increase of hospital outpatients in the district.
