目标:空气健康指数(AHI)捕获了空气污染和非最佳温度的综合影响,并有助于评估大气环境的整体健康风险。山东省是中国重要的工业基地,空气污染和非最佳温度对健康的影响不容忽视。构建山东省AHI,并评估研究区AHI造成的地区级死亡负担。
方法:每日特定地区死亡率,气象,收集了山东省2013-2018年的空气污染数据,中国。AHI结构最终包含PM2.5和NO2,O3以及非最佳温度。使用归因分数(AF)和归因数(AN)来估计归因于AHI的地区特定死亡率负担。
结果:山东省观测的AHI平均值为6。我们的研究揭示了总AHI和总死亡率之间的正相关,总体趋势是缓慢增长,然后是快速增长。暴露-反应曲线,当按性别分层时,年龄,和死因,与总体趋势大致一致。省级归因分数(AF)为5.31%(95%CI4.58%,5.91%),归因数(AN)为188,246(95%CI162,396,209,533)。总的来说,较高的AN主要出现在西南地区,而中东部和中北部地区的房颤值较高。
结论:空气健康指数在预测死亡负担方面表现良好,可以向公众传达与暴露于周围环境有关的健康风险。
OBJECTIVE: The air health index (AHI) captures the combined effects of air pollution and non-optimal temperatures and helps assess the atmospheric environment\'s overall health risk. Shandong Province is a crucial industrial base in China, and the health effects of air pollution and non-optimal temperature cannot be ignored. To construct an AHI for Shandong Province and assess the district-level mortality burden due to AHI in the study area.
METHODS: Daily district-specific mortality, meteorological, and air pollution data over 2013-2018 were collected in Shandong Province, China. The AHI construction eventually incorporated PM2.5 and NO2, O3, and non-optimal temperatures. Attributable fraction (AF) and attributable number (AN) were used to estimate the district-specific mortality burden attributable to AHI.
RESULTS: The average AHI value observed in Shandong Province was 6. Our research revealed a positive association between the total AHI and total mortality, with an overall trend of a slow increase followed by a rapid increase. The exposure-response curves, when stratified by gender, age, and cause of death, were approximately consistent with the overall trend. The provincial attributable fraction (AF) was 5.31% (95% CI 4.58%, 5.91%), and the attributable number (AN) was 188,246 (95% CI 162,396, 209,533). Overall, higher ANs mainly appeared in the southwestern area, while higher values of AF were observed in the central-eastern and central-northern areas.
CONCLUSIONS: The air health index performs well in predicting death burden and can convey health risks related to exposure to the ambient environment to the public.
