Abstract

Objectives: To construct an improved air health index (AHI) based on cardiovascular years of life lost (YLL) in Tianjin and assess its utility.

Methods: We derived the exposure-response coefficients from time-series models and calculated the excess YLL (EYLL) for simultaneous exposure to air pollution and non-optimum temperature. The AHI was developed using the EYLL at the WHO 2021 Air Quality Guideline annual mean values and optimum temperature as a reference. We assessed the validity of AHI by comparing the correlations and model fit between the AHI, air quality health index (AQHI), and air quality index (AQI) with cause-specific YLLs.

Results: Each inter quartile range (IQR) increase in AHI was associated with 256.31 (95%CI: 183.05, 329.57), 150.34 (95%CI: 108.23, 192.46), 90.41 (95%CI: 64.80, 116.02) and 60.80 (95%CI:33.41, 88.18) person-year increments for non-accidental, cardiovascular, ischaemic, and cerebrovascular YLL, respectively. The AHI, in contrast to the AQHI and AQI, showed the strongest correlations with the risks of cause-specific YLLs, both in the total population and subpopulations.

Conclusion: The AHI based on cardiovascular YLL has a greater predictive ability for health risks.

基于短期心血管影响的中国天津空气健康改进指数。

目的根据天津市心血管疾病的寿命损失年数（YLL）构建改进的空气健康指数（AHI），并评估其实用性：方法：我们从时间序列模型中推导出暴露-反应系数，并计算出同时暴露于空气污染和非最佳温度时的超额寿命损失年数（EYLL）。AHI 是以世界卫生组织 2021 年空气质量指南年均值和最适宜温度下的 EYLL 作为参考值而得出的。我们通过比较 AHI、空气质量健康指数 (AQHI) 和空气质量指数 (AQI) 与特定原因 YLL 之间的相关性和模型拟合度来评估 AHI 的有效性：AHI每增加一个四分位数间范围（IQR），非意外事故、心血管、缺血性和脑血管YLL分别增加256.31（95%CI：183.05，329.57）、150.34（95%CI：108.23，192.46）、90.41（95%CI：64.80，116.02）和60.80（95%CI：33.41，88.18）人年。在总人口和亚人口中，AHI与AQHI和AQI相比，与特定病因YLL风险的相关性最强：结论：基于心血管永利国际娱乐的 AHI 对健康风险的预测能力更强。
