ObjectiveTo systematically review the disease burden of pneumoconiosis in Chinese population so as to provide references for health resources allocation and health policy making.MethodsDatabases including PubMed, EBSCO, Web of Science, CNKI, WanFang Data and VIP databases were searched for studies on investigation of the disease burden of pneumoconiosis in Chinese population from inception to 31st January, 2020. Two reviewers independently screened literature, exacted data, and assessed risk of bias of included studies. Systematic review was performed on data of pneumoconiosis associated population, mortality, and disease burden.ResultsA total of 26 studies were included. Qualitative analysis showed that the decrease of DALY and YLL of pneumoconiosis in China had been lower than that in globally, and the increase of YLD had been higher than that in globally in recent 10 years. 14 factors were included in the analysis of influencing factors on the financial burden or hospitalization expenses of pneumoconiosis patients; among them, the length of hospitalization, related complications, and pneumoconiosis stage were the most important indexes which had influence or difference on patients’ financial burden (or hospitalization expenses). The burden of pneumoconiosis in the Chinese population was primarily concentrated on males. Occupational diseases caused most of them, and middle-aged and older adults were the primary population for pneumoconiosis. However, young patients due to early-onset age, long course of disease and complications, and other factors resulting in a larger YLD phenomenon should also be considered.ConclusionsThe disease burden of pneumoconiosis patients in China is still heavy. It is recommended to continue to reduce the DALY of pneumoconiosis among the Chinese population as a long-term goal, and to strengthen control strategies to curb the early onset and death of pneumoconiosis.
ObjectiveTo analyze the epidemiological burden and change trend of five sexually transmitted infections (STIs) in China from 1990 to 2019. MethodsThe estimated numbers and standardized rates of STIs incidence, prevalence, and disability-adjusted life years (DALY) in China and other regions were obtained from the Global Burden of Disease Study 2019. The epidemic burden and change trend of STIs in China were compared and evaluated. ResultsIn 2019, STIs affected about 242 million people in China, resulting in 173 million new cases and 350 000 person years of DALY losses. Compared with 1990, the prevalence and incidence of STIs increased by 59.75% and 30.02%, respectively, and the number of DALY decreased by 35.19%. From 1990 to 2019, the incidence rate of chlamydia infection and gonococcal infection in the young and middle-aged group (aged 15-49 years) showed an upward trend; in addition, the DALY rate of genital herpes and trichomoniasis also increased. Among the 5 STIs, the disease burden caused by trichomoniasis infection in women was much higher than that in men. With the increase in the socio-demographic index (SDI), the burden of STIs in China gradually decreased. After the SDI exceeded 0.65, the decline rate of standardized DALY rate sharply increased. ConclusionThe disease burden of STIs in China shows a downward trend from 1990 to 2019, and the disease burden of the young and middle-aged group (aged 15-49 years) is the most significant, especially in trichomoniasis and chlamydia infection.
