  • 摘要:   目的  估算中国不同气温带气温健康预警的阈值,为发展基于死亡风险的气温健康预警系统提供科学依据。  方法  收集2006―2017年全国364个县、区作为研究点的死亡与气象数据,利用分布滞后非线性模型(distribution lag non-linear model, DLNM)和多变量Meta方法分析气温与死亡的暴露反应关系,划分气温预警阈值。  结果  研究期间日平均气温16.0 ℃,日平均相对湿度73.0%,日均死亡人数为8.3例。不同气温带的气温-死亡的暴露反应关系总体上呈倒“J”型。中温带、暖温带+北亚热带、中亚热带以及南亚热带冷效应低风险气温范围分别9.1~13.8 ℃、0.1~19.3 ℃、8.8~24.3 ℃以及9.9~25.3 ℃,中风险分别为1.8~9.1 ℃、-6.1~0.1 ℃、1.5~8.8 ℃以及4.8~9.9 ℃,高风险分别为<1.8 ℃、<-6.1 ℃、<1.5 ℃以及<4.8 ℃;热效应低风险气温范围分别为23.4~24.8 ℃、28.6~29.3 ℃、27.2~29.5 ℃以及28.2~28.6 ℃,中风险分别为24.8~26.1 ℃、29.3~30.1 ℃、29.5~31.0 ℃以及28.6~29.0 ℃,高风险分别为>26.1 ℃、>30.1 ℃、>31.0 ℃以及>29.0 ℃。所有气温带在高温端的日均死亡人数均随着风险等级增加而升高,而除了暖温带+北亚热带外,其他气温带在低温端的日均死亡人数随着风险等级增加而升高。  结论  基于死亡风险可以确定气温预警的阈值并进行预警等级划分,预警效果较好。
