目的了解北京市非职业性一氧化碳中毒事件的发生状况,分析其流行病学特征,探讨有效的预防控制措施。方法采用描述性流行病学方法,对2006-2013年度北京市非职业性一氧化碳中毒事件流行特征进行分析,率的比较采用检验。结果 2006-2013年度北京市共报告非职业性CO中毒事件11 768起,中毒16 132人,死亡259人。93.9%(11 050/11 768)非职业性CO中毒事件发生在居民家庭内,99.9%(11 046/11 050)的居民家庭CO中毒事件为未分级事件。居民家庭CO中毒事件集中发生在冬季,高峰为每年11月至翌年3月。自2010年开始推广CO中毒报警器,除2012年度居民家庭CO中毒事件的发生有所回升外,其余年度呈现下降趋势。结论 2010年开始推广安装CO报警器后,北京市居民家庭CO中毒事件报告的起数、中毒人数和死亡人数均呈现总体下降趋势。安装CO报警器可减少居民家庭内CO中毒事件的发生。
Objective To understand the occurrence of non-occupational carbon monoxide poisoning in Beijing, analyze its epidemiological characteristics and explore effective prevention and control measures. Methods Descriptive epidemiological methods were used to analyze the epidemiological characteristics of non-occupational carbon monoxide poisoning in Beijing from 2006 to 2013, and the rates were compared using tests. Results In 2006-2013, a total of 11 768 cases of non-occupational CO poisoning were reported in Beijing. There were 16 132 poisonings and 259 deaths. 93.9% (11 050/11 768) of non-occupational CO poisoning incidents occurred in residential households, and 99.9% (11 046/11 050) of CO poisoning incidents were classified as unfractionated events. CO poisoning in residential households concentrated in the winter, the peak for every year in November to March the following year. Since 2010, the promotion of CO poisoning alarms has shown a downward trend in other years except for the occurrence of CO poisoning in residential households in 2012. Conclusion After the popularization and installation of CO alarm in 2010, the number of poisonings and the number of poisoning and death toll of CO poisoning in Beijing residents showed an overall downward trend. Install CO alarm can reduce the occurrence of CO poisoning in residential households.
