Disease burden of dementia attributed to high BMI in 1990–2019 / 公共卫生与预防医学

Objective To understand the changing trend of dementia disease burden attributed to high BMI in China from 1990-2019, and to provide a basis for the development of dementia prevention and control strategies. Methods Using data from the Global Burden of Disease Study 2019(GBD2019)，the changes in disease burden were analyzed using indicators such as deaths, disability adjusted life years (DALYs), years lived with disability (YLDs), years of life lost (YLLs) and their standardized rates. The differences between sexes and age groups were compared. Joinpoint regression model was used to analyze the trend of changes in the disease burden of dementia attributable to high BMI in China. Results From 1990 to 2019, the burden of dementia disease attributed to high BMI continued to increase, with 20,300 more deaths, 404,200 more DALYs, and more than a four-fold increase in both mortality and DALYs rates. The overall burden of disease was greater for women than for men, but the rate of increase in the burden of disease was higher for men than for women. The disease burden in the age group of 80 and over was significantly higher than in other age groups. Conclusion Attention should be paid to people with high BMI, especially for the prevention and control of dementia risk in older age groups with high BMI. Active countermeasures should be taken to control the occurrence of dementia.

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.

Disease burden on falls among 0-19 years old population in China, in 1990 and 2017 / 中华流行病学杂志

Objective@#To analyze and compare the disease burden of falls in Chinese population aged 0-19, in 1990 and 2017.@*Methods@#Indicators including number of deaths, mortality rates, years of life lost due to premature mortality (YLL), years lived with disability (YLD) and disability-adjusted of life years (DALY), on falls, were gathered from the Global Burden of Disease (GBD) 2017 and used to describe the disease burden and corresponding parameters on falls, between 1990 and 2017, in China.@*Results@#In 2017, number of death, YLLs, YLDs, DALYs caused by falls were 5 321, 0.43 million person years, 0.14 million person years and 0.57 million person years respectively, among aged 0-19 group. Rates on standardized mortality, YLLs, YLDs and DALYs on falls were 1.76/100 000, 141.49/100 000, 46.99/100 000, and 188.48/100 000, respectively. The burden of falls decreased with the increase of age. Compared with 1990, disease burden of falls decreased in all age groups, both in male and female, with more seen in the lower age groups. Compared with 1990, the number of deaths, rates on YLLs, YLDs and DALYs caused by falls decreased by 65.08%, 46.63%, 47.38% and 36.33% respectively, in 2017. However, the YLDs rate increased by 73.31% between 1990 and 2017. The ratio of YLLs to DALYs decreased from 90.84% in 1990 to 75.07% in 2017, with a proportion as 17.36%.@*Conclusion@#Compared with 1990, although the disease burden of falls among aged 0-19 group showed a decreasing trend, falls still caused serious disease burden for the aged 0-19 group. Research that targeting prevention on falls, should be continued.
