摘要
目的探讨北京市夏季最低气温对心脑血管疾病(ICD10:I00～I99)急诊的影响。方法收集2004—2006年北京大学某医院急诊科心脑血管疾病急诊资料、北京市环境监测中心大气污染物数据和中国气象科学数据共享服务网的气象资料,应用时间分层的病例交叉设计研究方法进行数据分析。结果在控制大气污染物SO2、NO2、可吸入颗粒物(PM10)影响的情况下,无滞后夏季最低气温对心脑血管疾病总急诊、冠心病急诊、心律失常急诊、心衰急诊和脑血管疾病急诊的影响最大,气温每升高1℃,OR值分别为1.039(95%CI:1.008～1.071),1.077(95%CI:0.987～1.174),1.037(95%CI:0.963～1.116),1.103(95%CI:0.909～1.339)和1.030(95%CI:0.985～1.077),其中最低气温与总心脑血管疾病急诊的关联有统计学意义(P<0.05)。在多因素模型中,考虑到相对湿度因素时,气温每升高1℃对冠心病急诊和脑血管病急诊的OR值分别为1.095(95%CI:1.001～1.075)和1.050(95%CI:1.002～1.100),关联具有统计学意义(P<0.05)。结论夏季最低气温升高可以导致心脑血管疾病总急诊增加,同时相对湿度可能与气温有协同作用,可导致冠心病急诊,脑血管病急诊增加。
Objecfive To explore the association between the minimum temperature in different seasons and the hospital emergency room visits for cardiocerebrovascular diseases （International Classification of Diseases, tenth vision ICD- 10： I00-I99） in Beijing, China. Methods The data of the daily hospital emergency room visits for cardiocerebrovascular diseases（ICD-10： I00- I99） from one of Peking university hospitals, the data of relevant ambient air pollution from the Beijing Municipal Environmental Monitoring Center and the data of meteorological index from China meteorological data sharing service system between 2004-- 2006 were collected The time-stratified case-crossover design was used to analyze the data. Results After adjusting SO2, NO2, and PM10, the results showed that each 1 ℃ increase in the daily minimum temperature in summer was associated with the intraday hospital emergency room visits （OR=1.039, P〈0.05） for the total cardiocerebrovascular diseases. In multi-factor model, considering relative humidity, 1℃ increase in the daily minimum temperature was associated with the coronary heart disease （OR=1.095, 95% CI： I .001-1.075） and the cerebrovascular diseases （OR =1.050, 95%CI：1.002-1.100）（P〈0.05）. Conclusion These outcomes suggest that elevated level of minimum temperature in summer will increase the hospital emergency room visits for the total circulatory diseases, and the relative humidity may enhance the effects of minimum temperature on the hospital emergency room visits of coronary heart disease and cerebrovascular diseases.
