Analysis of disease burden of occupational pneumoconiosis in Gansu Province from 2010 to 2020 / 中华劳动卫生职业病杂志

Objective: Through comparative analysis of the disease burden of occupational pneumoconiosis in Gansu Province from 2010 to 2020, the main influencing factors are screened, and scientific basis is provided for rational allocation of limited health resources, precise management and policy implementation. Methods: In August 2021, survey and collect information on surviving occupational pneumoconiosis patients and dead occupational pneumoconiosis patients diagnosed in Gansu Province from 2010 to 2020, and analyze and calculate indicators such as morbidity, mortality, and disability adjusted of life years (DALY). Analyzing the influencing factors of disease burden usirrg multiple linear regression. Results: From 2010 to 2020, the average annual incidence of occupational pneumoconiosis in Gansu Province was 0.9992/100000, the average annual mortality was 0.897/100000, the cumulative case fatality rate was 25.75%, and the cumulative DALY was 28932.96 person-years. The first stage of occupational pneumoconiosis was the highest among DALY loss (19920.14 person-years), and the DALY loss was positively correlated with the stage of occupational pneumoconiosis. Among occupational pneumoconiosis in Gansu Province, silicosis (13753.66 person-years) and coal worker's pneumoconiosis (13414.73 person-years) caused the highest disease burden, followed by cement pneumoconiosis and asbestos lung. Period, length of service, type of disease, and region are all influencing factors of DALY loss (P<0.05). Conclusion: From 2010 to 2020, the DALY losses caused by occupational pneumoconiosis in Gansu Province showed a fluctuating decrease, with the composition of DALY mainly changing from the loss of life years due to premature death to the loss of years due to injury and disability.

Current situation and trend analysis of AIDS burden in China, the United States and Japan / 公共卫生与预防医学

Objective By analyzing the incidence, prevalence, mortality, Disability Adjusted of Life Years (DALY) situations and trends of AIDS in China from 1990 to 2019, this paper provides scientific basis for the preventions and controls of AIDS in China. Methods The incidence, prevalence, mortality and DALY rate of AIDS from 1990 to 2019 are obtained from GBD 2019 data. The standardardized rate of four indicators are used to compare and analyze the AIDS changes in China, the United States, Japan and the global with the development of years. Results The four indicators of AIDS in China present increasing trends, with male higher than female. The incidence rate increased from 0.82/100 000 in 1990 to 2.24/100 000 in 2019, the prevalence increased from 5.63/100 000 to 38.77/100 000, and the mortality increased from 0.23/100 000 to 2.23/100 000. The DALY rate increased from 13.18/100 000 to 98.15/100 000. Compared with the global and the United States, the standardized rate of four indicators of AIDS in China in 2019 showed a trend of low level, but it was higher than that in Japan. Conclusion In recent years, some progress has been made in AIDS preventions and controls in China, but the disease burden of AIDS is still on the rise. The situation of AIDS preventions and controls is still serious and unremitting efforts should be made to reduce the burden of AIDS.
