摘要
目的分析主要大气污染物(SO2、NO2、PM10)急性暴露对广州市居民每日心血管疾病急诊人次的影响。方法采用时间序列的半参数广义相加模型,将居民每13心血管疾病急诊人次的长期趋势、气象因素、”星期几效应”等混杂因素控制后,分析广州市2006年8月1日至2007年10月21日大气PM10、SO2、NO2浓度与居民每日心血管疾病急诊人次的关系。结果大气PM10、SO2、NO2浓度每增加10μg/m^3,广州市心血管疾病急诊人次分别增加0.38%(95%CI:-0.2%~0.96%),1.17%(95%CI:0.41%,1.94%)和1.28%(95%CI:0.5%~2.06%),后两者有统计学意义(P〈0.05)。结论本次调查期间广州市大气SO2、NO2污染能增加居民心血管疾病急诊人次。
Objective To assess the relationship between acute exposure to air pollutants (PM10, SO2 and NO2) and daily cardiovascular emergency visits in Guangzhou. Methods Semi-parametric generalized additive model was used to analyze the relationship between air PM10, SO2, NO2 concentrations and daily cardiovascular emergency visits from August I, 2006 to October 21, 2007 in Guangzhou after adjustment for time trends, weather conditions and "days of the week". Results An increase of 10 ttg/m3 of PM10, SO2 and NO2 was associated with an increase of 0.38% (95%CI: -0.2%-0.96%), 1.17% (95%CI: 0.41%-1.94%), 1.28% (95%CI: 0.5%-2.06%) of cardiovascular emergency visits respectively. Conclusion SO2 and NO2 are significantly associated with increased risk of cardiovascular emergency visits in Guangzhou.
