Objective: To analyze the burden of disease attributable to high temperature exposure in China and globally from 1990 to 2019, and to study the current burden of disease in relevant populations. Methods: In October 2021, based on data from the global burden of disease 2019 (GBD 2019) study, population attributable fraction (PAF), number of deaths, mortality, disability-adjusted life year (DALY) and DALY rate of Chinese and global populations with different ages and genders in 1990 and 2019 were extracted and analyzed. The rate of change was calculated, the mortality rate was normalized by the age structure of the world standard population, and the causes of disease burden caused by high temperature exposure of Chinese residents were analyzed. Results: In 2019, compared with 1990, the PAF of Chinese and global population decreased by 43.98% and 12.41% respectively, the number of deaths increased by 29.55% and 49.40% respectively, the crude mortality rate increased by 7.81% and 3.30% respectively, the DALY decreased by 48.12% and 14.41% respectively, and the DALY rate decreased by 56.82% and 40.82% respectively. The mortality rate of the ≥70 age group was higher than that of other groups. The disease burden indicators such as PAF, standardized mortality and DALY attributable to high temperature exposure in men were higher than those in women. In 2019, the main cause of DALY affected by high temperature exposure in Chinese population was ischemic heart disease (84400 person-years), and the main cause of death was ischemic heart disease (4900 cases). Conclusion: The burden of diseases attributable to high temperature exposure is still serious in China and the world at large. Targeted interventions should be formulated for men, the elderly and people with occupational exposure, and a sound surveillance system should be established to reduce the burden of diseases caused by high temperature exposure.
目的： 分析1990至2019年中国及全球归因于高温暴露的疾病负担，研究相关人群疾病负担现状。 方法： 于2021年10月，通过2019年全球疾病负担（GBD 2019）研究数据，提取并分析1990年与2019年不同年龄及性别中国及全球人群归因于高温暴露的人群归因分值（PAF）、死亡数、死亡率、伤残调整寿命年（DALY）以及DALY率等指标，计算变化率，通过世界标准人口的年龄结构对死亡率进行标化，并分析中国居民高温暴露造成疾病负担的原因。 结果： 2019年中国及全球人群PAF较1990年分别下降43.98%、12.41%，死亡数分别上升29.55%、49.40%，粗死亡率分别上升7.81%、3.30%，DALY分别下降48.12%、14.41 %，DALY率分别下降56.82%、40.82%；≥70岁年龄组人群的死亡率高于其他年龄群组；男性归因于高温暴露的PAF、标化死亡率、DALY等疾病负担指标均高于女性。2019年中国人群因高温暴露的影响DALY的主要原因是缺血性心脏病（8.44万人年），影响死亡的主要原因也是缺血性心脏病（0.49万例）。 结论： 中国及全球归因于高温暴露的疾病负担仍然较为严重，应对男性、老年群体及职业暴露人群制定针对性干预措施，建立完善的监测体系，降低高温暴露造成的疾病负担。.
