ABSTRACT
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.

OBJECTIVE: To analyze the funding status of the National Natural Science Fund(NNSF) in the field of occupational respiratory disease(ORD) research in China. METHODS: Through the NNSF Committee Science Foundation sharing service network database, we collected the information of funded projects in the field of ORD research in China from 1987 to 2018, and analyzed the funding expenditure, funding categories, supporting units and research contents. RESULTS: A total of 106 NNSF funded projects were obtained in the research field of ORD in China in the period 1987-2018, and the total amount of funding was 37.945 million yuan. The number of funded projects, the average and the total amounts of fundings showed an increasing trend year by year(all P<0.05). The main types of funded projects were general projects and Youth Science Foundation projects(97.2%). The funded projects and funds were mainly concentrated in colleges and universities, accounting for 79.2% and 83.4% respectively. Beijing(29 items, 27.4%), Hebei(13 items, 12.3%) and Jiangsu(11 items, 10.4%) were the top three provinces and municipalities in the number of funded projects. Silicosis, pulmonary fibrosis, quartz, alveolar macrophages and acute lung injury were the top five keywords of funded project items, and the research types mainly focused on the mechanism of diseases. CONCLUSION: The NNSF funding is imbalanced in the types of funding, supporting units, and regional distribution on ORD research field in China. It is suggested that the funding structure of NNSF should be optimized, interdisciplinary research should be encouraged and expanded, and cooperation among different institutions and regions should be promoted.
