To construct an improved air health index (AHI) based on cardiovascular years of life lost (YLL) in Tianjin and assess its utility.
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.
Each inter quartile range () increase in AHI was associated with 256.31 (95%: 183.05, 329.57), 150.34 (95%: 108.23, 192.46), 90.41 (95%: 64.80, 116.02) and 60.80 (95%: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.
The AHI based on cardiovascular YLL has a greater predictive ability for health risks.
基于天津市心血管寿命损失年（YLL）构建改良的空气健康指数（AHI），并评估其效用。
我们从时间序列模型中推导出暴露反应系数，并计算同时暴露于空气污染和非最佳温度下的超额 YLL（EYLL）。AHI 是根据世界卫生组织 2021 年空气质量指南的年平均值和最佳温度下的 EYLL 以及参考温度来制定的。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来评估 AHI 的有效性。
AHI 每增加一个四分位距（IQR），与非意外、心血管、缺血性和脑血管 YLL 分别增加 256.31（95%置信区间：183.05，329.57）、150.34（95%置信区间：108.23，192.46）、90.41（95%置信区间：64.80，116.02）和 60.80（95%置信区间：33.41，88.18）人年增量相关。与 AQHI 和 AQI 相比，AHI 与全人群和亚人群特定原因 YLL 的风险具有最强的相关性。
基于心血管 YLL 的 AHI 对健康风险具有更大的预测能力。
