【摘要】：目的探讨北京2013年1月雾霾事件PM_(2.5)暴露对城区和郊县居民呼吸系统疾病死亡影响的急性健康效应。方法收集2013—2014年间北京PM_(2.5)浓度、温度、相对湿度,以及二区县(某城区和某郊县)呼吸系统疾病死亡数据;以连续3 d以上超过2013—2014年PM_(2.5)年均浓度为基准对2013年1月雾霾事件划分时间段;基于流行病学事件回顾性研究,使用广义线性模型,同时控制星期效应、死亡时间趋势、日均温和日相对湿度等混杂因素,分析北京2013年1月雾霾事件各时间段内人群呼吸系统疾病死亡风险是否与非雾霾事件期存在差异,并通过敏感性分析观察模型稳定性。结果 2013—2014年北京PM_(2.5)年平均浓度和2013年1月雾霾事件期间PM_(2.5)日均浓度分别是99.75μg/m~3和194.30μg/m~3。广义线性模型结果显示与2013—2014年非雾霾事件期比较,该雾霾事件1月10—16日时间段内PM_(2.5)污染暴露使得二区县居民呼吸系统疾病死亡风险分别提高75.93%(95%CI:14.13%~171.21%)和147.81%(95%CI:11.62%~450.16%);而在后续两个雾霾时间段(1月18—23日和1月26—31日)中PM_(2.5)暴露对于呼吸系统疾病死亡的影响与非雾霾事件期无统计学差异(P0.05)。结论北京2013年1月10—16日雾霾事件PM_(2.5)高暴露期所致人群呼吸系统死亡风险增加。
[Abstract]:Objective to investigate the acute health effects of haze events in Beijing (January 2013) on the mortality of respiratory diseases in urban and suburban counties.Methods from 2013 to 2014, the concentration, temperature, relative humidity and death data of respiratory system diseases in two districts (one city and one suburb) in Beijing were collected.The haze events in January 2013 were divided according to the average annual concentration of more than 3 consecutive days over 2013-2014. Based on the retrospective study of epidemiological events, the generalized linear model was used to control the week effect and the trend of death time.The risk of death of respiratory system disease in Beijing during January 2013 haze event was compared with that in non-#en1# event period, and the stability of the model was observed by sensitivity analysis.Results the average annual concentration in Beijing between 2013 and 2014 was 99.75 渭 g/m~3 and 194.30 渭 g / mg. respectively, and the average daily concentration during the haze event in January 2013 was 99.75 渭 g/m~3 and 194.30 渭 g / mg. respectively.The results of the generalized linear model show a comparison with the 2013-2014 non-haze event period.The haze incident during the 10-16 January period) pollution exposure raised the risk of death from respiratory diseases in residents of the two districts by 75.93% or 95% CI: 14.131.21) and 147.8195 CI: 11.62) 450.16; and in the following two haze periods (18-23 January and 26-31 January)There was no significant difference in the effects of exposure to respiratory diseases on mortality of respiratory diseases compared with non-#en0# event period (P 0.05).Conclusion the risk of respiratory death caused by haze events in Beijing increased during the period of high exposure.
