摘要

综合的空气健康指数有助于强调多种大气危险因素的健康风险，有利于向公众传达不良大气环境的总体风险。本文试图通过整合我国大气污染和非适宜温度相关的每日死亡风险，建立一种新的空气健康指数（Air Health Index, AHI）。本研究从时间序列模型中获得了暴露-反应系数，通过将 2013—2015 年我国 272个城市大气污染物与非适宜温度相关的超额死亡风险求和，构建了新的AHI。估计了基于总死亡率构建的AHI（'总AHI'）与全死因死亡率的关系，并进一步比较了'总AHI'与'特异性AHI'（基于疾病别死亡率构建）在预测心肺系统疾病死亡率方面的能力。研究发现，空气污染和非适宜温度与28.23%的每日超额死亡率有关，其中23.47%与非适宜温度有关，其余的与PM_2.5（1.12%）、NO₂（2.29%）和O₃（ 2.29%）有关。新的AHI采用了10分制的评分标准，272座城市的平均AHI为6分。AHI与死亡率关系的暴露-反应曲线呈线性，不存在阈值。'总AHI'每增加一个单位，全死因死亡率增加0.84%，心血管疾病、冠心病、中风、呼吸系统疾病和慢性阻塞性肺疾病的死亡率分别增加1.01%、0.98%、1.02%、1.66%和1.71%。使用'总AHI'估计疾病别死亡率风险与使用'特异性AHI'预测的疾病别死亡率风险相似。综上所述，本研究提出的'总AHI'可能是一种有前途的风险交流工具，有利于向公众传达与大气环境有关的健康风险。

Abstract

A composite Air Health Index (AHI) is helpful for separately emphasizing the health risks of multiple stimuli and communicating the overall risks of an adverse atmospheric environment to the public. We aimed to establish a new AHI by integrating daily mortality risks due to air pollution with those due to non-optimum temperature in China. Based on the exposure-response (E-R) coefficients obtained from time-series models, the new AHI was constructed as the sum of excess mortality risk associated with air pollutants and non-optimum temperature in 272 Chinese cities from 2013 to 2015. We examined the association between the ″total AHI″ (based on total mortality) and total mortality, and further compared the ability of the ″total AHI″ to predict specific cardiopulmonary mortality with that of ″specific AHIs″ (based on specific mortalities). On average, air pollution and non-optimum temperature were associated with 28.23% of daily excess mortality, of which 23.47% was associated with non-optimum temperature while the remainder was associated with fine particulate matter (PM_2.5) (1.12%), NO₂ (2.29%,), and O₃ (2.29%). The new AHI uses a 10-point scale and shows an average across all 272 cities of 6 points. The E-R curve for AHI and mortality is approximately linear, without any thresholds. Each one unit increase in ″total AHI″ is associated with a 0.84% increase in all-cause mortality and 1.01%, 0.98%, 1.02%, 1.66%, and 1.71% increases in cardiovascular disease, coronary heart disease, stroke, respiratory diseases, and chronic obstructive pulmonary disease mortality, respectively. Cause-specific mortality risk estimates using the ″total AHI″ are similar to those predicted by ″specific AHIs.″ In conclusion, the ″total AHI″ proposed herein could be a promising tool for communicating health risks related to exposure to the ambient environment to the public.

1、引言

大气污染和非适宜温度均与心血管疾病及呼吸系统疾病死亡风险增加有关[1‒2]。据估计，2019年空气污染造成我国185万人死亡以及4251万残疾调整寿命年[3]。为了降低与空气污染相关的疾病负担，各国采用空气质量指数（AQI）向公众发布空气污染水平以及相关暴露的健康风险。然而，目前的AQI指数仅由具有最高AQI指数的空气污染物决定，而没有考虑同时暴露于多种空气污染物对健康的综合影响。

在全球气候变化的背景下，非适宜温度成为全球的健康挑战，特别是在发展中国家。据估计，中国14.33%的非意外死亡是由环境非适宜温度造成的[1]。目前用于指示环境温度造成的健康风险的指数，如热浪指数和寒潮指数只考虑了极端温度[4‒5]，而没考虑归因于中等非适宜温度所造成的更大的疾病负担。因此，热浪指数和寒潮指数可能大大低估了由非适宜温度引起的疾病负担。此外，热浪和寒潮指数是根据每日气温变化来定义的，没有考虑环境温度与人口健康之间的关系。

在真实世界中，人们往往同时暴露于空气污染和大气温度。并且这些环境因素在诱发急性不良健康效应方面有相似的生物学途径，如炎性、氧化应激、生热作用和自主神经功能的变化[6‒7]。因此，同时向公众传达空气污染和非适宜温度的健康风险对于保护易感人群来说至关重要。然而，目前还没有任何指数同时考虑非适宜温度和空气污染的综合健康风险。因此，有必要建立一种新的空气健康指数（AHI），将环境空气污染和非适宜温度的健康风险整合起来，以便让公众更好地了解暴露于这些环境因素的整体健康风险，帮助人们有效地减少相关暴露、减轻潜在的危害。

本研究拟利用全国性数据库、综合环境空气污染和非适宜温度导致的死亡风险，建立新的AHI，并评估AHI与我国每日死亡率的关系。新的AHI还将提供每种危险因素导致的每日超额死亡人数。此外，还对基于总死亡率构建的“总AHI”与基于疾病别死亡率构建的“特异性AHI”的预测能力进行比较，以评价针对特定疾病开发“特异性AHI”的必要性。

2、材料与方法

2.1 数据来源

分析是基于2013年1月1日至2015年12月31日全国272座城市的每日死亡率、空气污染物水平和天气状况数据进行的。关于数据集的详细信息在以往的研究[8‒10]中已有详细介绍。简而言之，这272座城市分布在我国31个省级行政区域，人口数量覆盖总人口数量的20%（近2.9亿）。这些城市的每日死亡人数包括全死因死亡人数和疾病别死亡人数；这些数据来自中国疾病监测点系统，该系统在国家级和省级水平上具有较好的代表性[11‒12]。

本研究选择了细颗粒物（PM_2.5）、二氧化氮（NO₂）和臭氧（O₃）作为本次研究的代表性空气污染物。因为之前在同一个数据库中进行的研究发现，这三种污染物与死亡率之间有显著且稳定的关联[8,10,13]。PM_2.5、NO₂的每日平均浓度以及O₃的最大8 h平均浓度数据来源于全国城市空气质量实时发布平台（http://106.37.208.233:20035/）。该平台共有1265个监测站点，截至2015年，每个城市的监测站中位数量为4个（范围为1~7个）。计算这些城市所有有效监测站点的平均值，并将该平均值定义为该城市的每日空气污染物水平。各城市的每日平均气温和平均相对湿度数据来源于中国气象数据共享服务系统（http://data.cma.cn/）。本研究方案获得复旦大学公共卫生学院评审委员会批准（No. 2014-07-0523）。

2.2 数据分析

首先通过时间序列分析获得每日空气污染和非适宜温度与全死因死亡率和死因别死亡率的关系。然后计算这些环境危险因素的每日超额死亡风险。最后将每日超额死亡风险除以最大加权平均超额死亡风险，再乘以10，得到全国AHI。

2.2.1. 时间序列分析

首先，排除了环境空气污染和非适宜温度数据中低于第2.5百分位数或高于第97.5百分位数的日历日，以减少极端值的影响。然后使用标准的时间序列分析获得每日PM_2.5、NO₂和O₃的单位变化相关的死亡率回归系数（1 μg·m^-3）。关于时间序列分析的细节在之前的研究中有详细的描述[1,8,13]。由于暖季和冷季空气污染物浓度不同，分别计算暖季（5~10月）和冷季（11月至来年4月）空气污染物的相对风险（RR），用于后续计算。协变量包括日历日的自然三次样条平滑函数[每年自由度（DoF）为7]、“星期几”（作为指示变量），以及当天的平均温度（DoF为6）和相对湿度（DoF为3）的自然平滑函数[14]。

对于温度，与之前的研究中所考虑的类似，采用21天移动平均温度，并将全死因死亡风险最低时的温度（即22.8 °C）作为最适宜温度[2]。之前的研究发现，温度和死亡率的暴露-反应曲线呈倒J型，在非最适宜温度时，死亡风险呈近似线性增加[2]。因此，假设温度和死亡率之间的关系是一个以最适宜温度为节点的分段线性函数。根据前期研究估算的极端低温（RR = 1.68）和极端高温（RR = 1.16）的相对风险，利用公式（1）和公式（2）计算单位温度（1 °C）变化相关的每日死亡率增加的系数。

C o e f f i c i e n t f o r C o l d = l n (1.68) / (22.8 - (- 1.4))

（1）

C o e f f i c i e n t f o r w a r m = l n (1.16) / (29.0 - 22.8)

（2）

式中，1.68和1.16分别为与极端低温和极端高温相关的每日总死亡率的相对风险；22.8为最适宜温度；-1.4和29.0分别为极端低温和极端高温的平均值。

2.2.2. 构建全国AHI

之前采用相同数据库进行的研究发现，PM_2.5和NO₂在暴露当天的效应值最大，而O₃在滞后两天的效应值最大[14]，因此分别采用PM_2.5和NO₂当天以及O₃滞后两天的RR估计值用于该步骤的计算。首先，利用公式（3）计算各城市空气污染（以0为参考值）和温度（以22.8 °C为参考值）的每日超额死亡风险。

E R_{i t} = 100 (e x p (β_{i} ∆ x_{i t}) - 1)

（3）

式中，ER_it是第t天与危险因素i（空气污染物或温度）相关的超额死亡率百分比；β为回归系数，表明危险因素i每变化一个单位（空气污染物为1 μg·m^-3；温度为1 °C），每日死亡率的增加量；Δx是第t天危险因子i的水平与参考水平（空气污染物为0，温度为22.8 °C）之间的差值。每日超额死亡风险是所有危险因素的超额死亡风险之和。本研究只针对所有风险因素的数据都完整的日历日进行计算。

接下来，引入加权平均超额死亡风险，以减少具有高空气污染水平或极端温度的小城市过度加权产生的影响。具体来说，分别提取各城市在冷、暖温度时的每日超额死亡率百分比最大值。计算所有城市每日最大值的平均值，然后分别用每个城市在冷、暖温度时的每日平均死亡人数的平均值进行加权。分别计算冷、暖温度时的加权平均超额死亡风险，公式如下：

c = \sum_{j = 1, \dots, n} [(m_{j} / \sum_{j = 1, \dots, n} m_{j}) (m a x_{t = 1, \dots, q} \sum_{i = 1, \dots, p} E R_{i j t})]

（4）

式中，c是研究期间272座城市在冷、暖温度时的最大加权平均超额死亡率百分比；m表示在第j个城市中的每日平均死亡人数；ER为第j个城市第t天第i个危险因素的超额死亡率百分比。

最后，用每日超额死亡率百分比除以最大加权平均超额死亡率百分比，再乘以10，得到全国低温和高温时的AHI，如公式（5）。

A H I = (10 / c) \cdot (E R_{P M_{2.5}} + E R_{N O_{2}} + E R_{O_{3}} + E R_{t e m p}) （5） 这一过程产生了一系列从0到10+的每日AHI值，大于10的值表示与这一天空气污染和温度相关的超额死亡风险大于当前数据库中观察到的最大加权平均超额死亡率（即 c ）。为了便于交流，将AHI值进行四舍五入取最接近的整数。 2.2.3. AHI的预测能力评估 通过估算2013—2015年我国272座城市的AHI与当天全死因死亡率和疾病别死亡率的关系，评估AHI在预测死亡率方面的表现。另外，使用在以往文献中描述的方法绘制全国AHI和死亡率的暴露反应曲线[15]。对于可能的非线性关系，使用B样条函数，在AHI的第25和第75百分位数上设置节点。 在本研究中，基于总死亡率构建“总AHI”，并基于疾病别死亡率（包括心血管疾病、冠心病、中风、呼吸系统疾病和慢性阻塞性肺病）构建了“特异性AHI”。进一步通过比较回归系数估计值和模型拟合优度[R 2 和赤池信息准则（AIC）]，评估“总AHI”和“特异性AHI”在预测死因别死亡率方面的表现。此外，通过将公式（5）中的10替换为500，将AHI的尺度调整到0~500（AHI 0~500 ），以便使该指数可与当前的AQI进行比较，并进一步将AHI 0~500 的预测能力与“总AHI”进行比较。 本研究进行了几项敏感性分析。将时间序列分析中使用的日历日自然三次样条平滑函数的自由度由每年的7调整为8或10；并在AHI构建中额外纳入其他空气污染物（PM 10 、SO 2 和CO）作为代表性污染物。所有统计分析使用R软件中的“mgcv”和“tlnise”软件包进行。双侧 p 值小于0.05认为有统计学意义。估计值以变化的百分比和95%置信区间表示。 3、 结果 3.1 构建AHI 本研究共纳入了272个城市。表1总结了2013—2015年我国272座城市的每日死亡人数、天气状况和空气污染物水平。PM 2.5 、NO 2 和O 3 的年平均值分别为56 μg·m -3 、31 μg·m -3 和77 μg·m -3 。272座城市的天气状况各不相同，平均气温（年平均）为15 °C（范围为-0.5~25 °C）。 表1 我国272座城市2013—2015年大气环境与健康数据描述 Variables Mean SD Minimum P25 Median P75 Maximum Number of daily non-accidental deaths Total 1616371220165 CVD 871361065 CHD 33012328 Stroke 44023533 Respiratory disease 23011334 COPD 22001229 Air pollutants PM 2.5 (μg·m ‒3) 562018415467127 NO 2 (μg·m ‒3) 31111022303866 O 3 (μg·m ‒3) 771436687787113 Weather Mean temperature (°C) 155 -0.5 12161825 Relative humidity (%) 68103561717791 每日PM 2.5 、NO 2 、O 3 和气温的 c 值及回归系数见表2。暖温度和冷温度时的 c 值分别为18.00和66.10。在较暖温度时，与PM 2.5 、NO 2 、O 3 和温度单位变化相关的全死因死亡率增加的回归系数分别为0.000171、0.000498、0.000090和0.0239；在较冷温度时分别为0.000212、0.000724、0.000214和0.0214。因此，给定任何一天和任何一个地点，较暖和较冷温度时的“总AHI”分别可以用公式（6）和公式（7）来计算。 表2 我国272座城市2013—2015年疾病别AHI公式中各个危险因素的系数 Diseases c value Coefficients for each pollutant and temperature PM 2.5 NO 2 O 3 Temperature Warm period CVD 24.30 0.000175 0.000511 0.000206 0.0321 CHD 21.60 0.000138 0.000705 0.000205 0.0295 Stroke 25.60 0.000258 0.000362 0.000172 0.0336 Respiratory disease 38.80 0.000264 0.000834 0.000110 0.0416 COPD 32.00 0.000397 0.001110 0.000140 0.0317 Total 18.00 0.000171 0.000498 0.000090 0.0239 Cold period CVD 91.10 0.000248 0.000858 0.000240 0.0270 CHD 100.00 0.000277 0.000779 0.000217 0.0275 Stroke 82.10 0.000178 0.000743 0.000194 0.0256 Respiratory disease 53.50 0.000368 0.000953 0.000440 0.0185 COPD 57.30 0.000480 0.001170 0.000539 0.0187 Total 66.10 0.000212 0.000724 0.000214 0.0214 A H I f o r w a r m p e r i o d = (10 / 18.00) \cdot 100 \cdot [e x p (0.0239 \cdot {(t e m p e r a t u r e -

The general public is not likely to be affected Active children and adults, and people with respiratory or CVDs, should limit prolonged outdoor exertion 6‒7 Red Unhealthy Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects Common protective measures: Active children and adults, and people with respiratory or CVDs, should avoid prolonged outdoor exertion and stay indoors with the doors and windows closed; everyone else, especially children, should limit prolonged outdoor exertion Specific adaptive measures: If air pollutants are the dominant risk factors, the above sensitive groups may take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, the above sensitive groups may take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions) 8‒9 Purple Very unhealthy Health warnings of emergency conditions. The entire population is likely to be affected Common protective measures: Active children and adults, and people with respiratory or CVDs, should avoid all outdoor exertion and stay indoors with the doors and windows closed; everyone else, especially children, should limit outdoor exertion Specific adaptive measures: If air pollutants are the dominant risk factors, everyone may take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, everyone may take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions) 10+ Maroon Hazardous Health alert: Everyone may experience more serious health effects Common protective measures: Everyone should avoid all outdoor exertion and stay indoors with the doors and windows closed Specific adaptive measures: If air pollutants are the dominant risk factors, everyone should take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, everyone should take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions) 4.4 优势和局限性 本研究有以下几个优点。首先，使用大型多城市数据集构建了一个全国AHI，因此，研究结果具有全国代表性。其次，与其他指标相比，AHI将非适宜温度和空气污染综合在一起，能够更好地反映现实生活中的实际暴露情景，得到更全面的风险评估。最后，AHI不仅可以提供同时暴露于多种危险因素的整体健康风险，还可以提供每个因素单独的超额死亡风险，从而更好地告知公众，促使公众寻求有针对性的防护措施。 本研究也有一定的局限性。首先，暴露数据（空气污染物和温度）来源于各个城市的固定监测站而非个体暴露，因此暴露错分是不可避免的。其次，受到发病数据可获得性的限制，本文只将最严重的健康事件（即死亡率）作为结局，没有考虑发病率。因此，目前的AHI可能无法捕捉到急性和相对较弱的健康影响。最后，该指数使用当地的暴露反应曲线进行构建，因此AHI的预测能力也与当地特征有关。在像整个国家这样的大区域，预测能力不如在大气和人口特征更为均质的小区域稳定。此外，受到数据可获得性的限制，无法在本研究中纳入近几年的数据来验证AHI的预测能力。 5、 结论 本研究基于2013—2015年我国272个城市中PM 2.5 、NO 2 、O 3 和温度与每日总死亡率的关系，构建了新的AHI。“总AHI”与全死因死亡率和疾病别死亡率显著相关。AHI和死亡率之间的暴露反应曲线近似线性，没有阈值。该指数为向公众传达暴露于不同大气危险因素相关的健康风险提供了一个灵活而有前途的工具。 参考文献 原文顺序 | 出版日期 | 本文引用 [1] Liu C, Chen R, Sera F, Vicedo-Cabrera AM, Guo Y, Tong S, et al.

AHI	Colors	Levels	Health implications	Cautionary statements
0‒1	Green	Good	Air quality and temperature are satisfactory, and air pollution and temperature pose little or no risk	None
2‒3	Yellow	Moderate	Air quality and temperature are acceptable; however, for some pollutants or temperature, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution or temperature	People with severe diseases should limit prolonged outdoor exertion
4‒5	Orange	Unhealthy for sensitive groups	Members of sensitive groups may experience health effects. The general public is not likely to be affected	Active children and adults, and people with respiratory or CVDs, should limit prolonged outdoor exertion
6‒7	Red	Unhealthy	Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects	Common protective measures: Active children and adults, and people with respiratory or CVDs, should avoid prolonged outdoor exertion and stay indoors with the doors and windows closed; everyone else, especially children, should limit prolonged outdoor exertion Specific adaptive measures: If air pollutants are the dominant risk factors, the above sensitive groups may take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, the above sensitive groups may take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions)
8‒9	Purple	Very unhealthy	Health warnings of emergency conditions. The entire population is likely to be affected	Common protective measures: Active children and adults, and people with respiratory or CVDs, should avoid all outdoor exertion and stay indoors with the doors and windows closed; everyone else, especially children, should limit outdoor exertion Specific adaptive measures: If air pollutants are the dominant risk factors, everyone may take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, everyone may take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions)
10+	Maroon	Hazardous	Health alert: Everyone may experience more serious health effects	Common protective measures: Everyone should avoid all outdoor exertion and stay indoors with the doors and windows closed Specific adaptive measures: If air pollutants are the dominant risk factors, everyone should take personalized protective measures (e.g., wearing a mask or respirator, using a home air purifier, and taking fish oil); if temperature is the dominant risk factor, everyone should take precautions to maintain suitable temperature conditions (e.g., using an air conditioner and dressing appropriately according to the weather conditions)
