In the context of climate change, most of the global regions are facing the threat of high temperature. Influenced by tropical cyclones in the western North Pacific Ocean, high temperatures are more likely to occur in central China, and the economic losses caused by heat are in urgent need of quantification to form the basis for health decisions. In order to study the economic burden of high temperature on the health of Wuhan residents between 2013 and 2019, we employed meta-analysis and the value of statistical life (VSL) approach to calculate the relative risk of high temperature health endpoints, the number of premature deaths, and the corresponding economic losses in Wuhan City, China. The results suggested that the pooled estimates of relative risk of death from high temperature health endpoints was 1.26 [95% confidence interval (CI): 1.15, 1.39]. The average number of premature deaths caused by high temperature was estimated to be 77,369 (95% CI: 48,906-105,198) during 2013-2019, and the induced economic losses were 156.1 billion RMB (95% CI: 92.28-211.40 billion RMB), accounting for 1.81% (95% CI: 1.14-2.45%) of Wuhan's annual GDP in the seven-year period. It can be seen that high temperature drives an increase in the premature deaths, and the influence of high temperature on human health results in an economic burden on the health system and population in Wuhan City. It is necessary for the decision-makers to take measures to reduce the risk of premature death and the proportion of economic loss of residents under the impacts of climate change.
在气候变化的背景下，大多数全球区域都面临着高温的威胁。受西北太平洋热带气旋的影响，中国中部地区更容易出现高温天气，因此迫切需要量化高温对健康造成的经济损失，为健康决策提供依据。为了研究 2013 年至 2019 年期间高温对武汉居民健康的经济负担，我们采用荟萃分析和生命统计价值（VSL）方法来计算高温健康终点、过早死亡人数和中国武汉市相应的经济损失的相对风险。结果表明，高温健康终点死亡的相对风险的汇总估计值为 1.26[95%置信区间（CI）：1.15，1.39]。估计 2013-2019 年期间，高温导致的平均过早死亡人数为 77369 人（95%CI：48906-105198），导致的经济损失为 1561 亿元人民币（95%CI：922.80-2114 亿元人民币），占这七年期间武汉市 GDP 的 1.81%（95%CI：1.14-2.45%）。由此可见，高温会导致过早死亡人数增加，高温对人类健康的影响会给武汉市的卫生系统和人口带来经济负担。决策者有必要采取措施，降低因气候变化导致的过早死亡风险和居民经济损失比例。
