上海市温度和大气污染对居民心血管疾病门急诊人数的影响
Effects of temperature and air pollution on outpatient and emergency visits for cardiovascular diseases in Shanghai
摘要
Abstract
Objective To explore the effects of temperature and air pollution on the number of daily outpatient and emergency department visits for cardiovascular diseases in shanghai.Methods The data of air pollution and temperature,and number of visits to outpatient and emergency departments for cardiovascular diseases in Shanghai were collected between January 2013 and December 2014.Poisson regression models incorporating natural spline smooth functions (generalized linear models,GLM) were used to adjust for long-term,seasonal trends and weekend effect,public holiday,as wells as other confounding factors.Results A total of 9,906,835 hospital visits of cardiovascular diseases were identified during study period.The primary pollutants were PM2.5,PM10,SO2 and NO2,and their average daily concentrations were 56.3,76,20.6 and 46.7 μg/m3,respectively.The relative risks (RR) of average temperature lower than 18 ℃ versus above 18 ℃ for cardiovascular incidence was 1.016(95％ CI:1.013-1.018).In warm season,with a 10 μg/m3 increase in concentrations of PM2.5,PM10,SO2 or NO2,the numbers of hospital visits for cardiovascular diseases increased by 0.502％ (95％ CI:0.464％-0.545％),0.251％ (95％ CI:0.221％-0.282％),2.716％ (95％ CI:2.558％-2.874％) and 1.496％ (95％ CI:1.421％-1.571％),respectively.In cold season,the corresponding values were 0.543％ (95％ CI:0.521％-0.570％),568％ (95％ CI:0.548％-0.587％),1.607％ (95％ CI:1.528％-1.685％),1.923％ (95％ CI:1.868％-1.978％),respectively.Furthermore,each primary pollutant had different lag effect on hospital visits.Conclusion Low temperature increases dally numbers of hospital visits of cardiovascular diseases;which also increase with the increasing concentrations of primary air pollutants after adjusting confounding factors.关键词
