摘要
目的探讨空气污染物〔可吸入颗粒物(PM10)、二氧化硫(SO2)、二氧化氮(NO2)、臭氧(O3)〕对心血管疾病门诊病人量和住院病人量的影响。方法收集深圳市中心区两大型综合医院的门诊量和住院病人量资料及同时期空气污染物浓度、气象监测资料,运用时间序列法进行回归分析,研究深圳中心城区2006年1月1日至12月31日空气污染物与居民心血管疾病发病的关系。结果空气污染物PM10、SO2、O3与医院住院病人量有一定相关性,随着污染物浓度的增加,医院的心血管内科住院病人量增加,并且有统计学意义。其中在空气污染严重的11、12月份心血管疾病的住院病人量最高。结论空气中PM10、SO2和O3是心血管疾病发病的环境病因,其中以O3影响最大。
Objective To explore the influence of air pollutants [ respirable particulate matter （PM10）, sulfur dioxide （ SO2 ）, nitrogen dioxide （ NO2 ） , ozone （ O3 ） ] on cardiovascular diseases of outpatients and inpatients. Methods The relationship between air pollution and the outpatients＇and inpatients＇ data of Shenzhen for cardiovascular disease were investigated by collecting the air pollution data, the meteorological data and cardiovascular diseases ＇data of outpatients and inpatients in Shenzhen city from January 1 to December. Regression analysis was carried out by the time series measures. Results Air pollutants （ PM10, SO2,O3 ） and inpatients data had certain pertinence, and was of statistical significance. With the increasing of the concentration of the pollutants, the number of the inpatients of cardiovascular diseases increased. During the most severe period of air pollution from November to December, the number of inpatients of cardiovascular diseases was the highest. Conclusion Air pollutants （PM10, SO2, O3 ） are the primary environmental pathogeny factor for cardiovascular diseases, especially ozone（O3）.
