ObjectiveTo systematically review the disease burden and epidemiological characteristics of diabetes mellitus in Chinese population, and to provide references for health resources allocation and health policy making. MethodsDatabases such as PubMed, EMbase, CNKI, VIP and WanFang Data were searched for studies investigating disease burden of diabetes mellitus in Chinese population up to January 1st, 2014. According to the inclusion and exclusion criteria, two researchers screened literature, exacted data, and assessed methodological quality of included studies. Statistical analysis was performed with the data of diabetes associated population, mortality and disease burden were analyzed. ResultsA total of 39 studies were included, one of which was not included for further qualitative analysis due to low quality. The results of qualitative analysis involving 38 studies showed that, since 1980, the prevalence of diabetes increased rapidly in China, especially in the younger age group. The disease burden of woman was higher than that of man; it was slightly higher in the city than in the countryside; but the gap between urban and rural areas was gradually narrowed. Disease burdens in Eastern, Central and Western regions orderly decreased, all of which were all at high levels. ConclusionThe disease burden of diabetes mellitus in China is seriously high and the prevention and control work is very hard. It is necessary to rationally and effectively allocate health resources based on different health demands in different regions among urban-rural and age groups; to reduce the burden in the elderly; and to pay more attention to the young age population at the same time. Besides, the emphasis of prevention should be placed on suppressing the increase of prevalence of diabetes mellitus and reducing disease burden due to its complications.
ObjectivesTo systematically review the disease burden and epidemiological characteristics of tuberculosis in the Chinese population, and to provide reference for health resources allocation and health policy making.MethodsDatabases such as PubMed, EMbase, CNKI, VIP and WanFang Data were searched for studies investigating disease burden of tuberculosis in Chinese population from inception to August 1st, 2017. Two researchers independently screened literature, exacted data and assessed methodological quality of included studies. Statistical analysis was performed on data of tuberculosis associated population, mortality and disease burden.ResultsA total of 40 studies were included. The results of qualitative analysis showed that, since 1990, the prevalence of tuberculosis and its disease burden in China decreased year by year. However, the disease burden per patient and the total economic burden in China showed an increasing trend, and the economical disease burden increased 1.6 times from 1993 to 2003. The disease burden of men was higher than that of women, and it was higher in the countryside than in the city. In 2004, the ratio of YLL per thousand people in rural and urban areas was 2.18, and the ratio was 1.29 in 2014. Additionally, the disease burden decreased gradually in western, central and eastern regions. In 2014, compared with 2004, YLL decreased by 1.11, while the central and eastern regions were 0.48 and 0.25, respectively. The gap between the gender, the urban and rural areas and the regions was not as significant as in previous.ConclusionsThe disease burden of tuberculosis in China is seriously high and the tuberculosis prevention and control work should take into consideration the epidemiological characteristics of tuberculosis and the trends of the disease burden. It is necessary to rationally and effectively implement health intervention programs and allocate health resources based on different health demands in different regions and age groups to reduce the morbidity and mortality, and to pay more attention to drug-resistant tuberculosis. Besides, the emphasis of prevention should be placed on reducing disease burden in the elderly and strengthening prevention in the young population.
ObjectiveTo investigate the epidemiological and economic burden of acute meningitis and encephalitis syndrome (AMES) in Jinan, so as to provide references for prevention and control of AMES. MethodsThe monitoring data of the AMES Special Reporting System of Jinan City from 2007 to 2014 was collected and the epidemiological characteristics of AMES were analyzed. A questionnaire survey was performed in AMES patients reported in 2013 to collect the basic information, prognosis, medical and non-medical expenses etc. of patients. The DALYs and economic burden of AMES were estimated by using SPSS 13.0 software. ResultsThe average incidence rate of AMES in Jinan was 8.49/100 000 through 2007 to 2014 and the mortality was 4.96‰. The total DALYs were 36 659.51 and the average DALY was 8.27.77.86% were aged less than 14 years old. The average direct economic burden of each case was 19.5 thousand RMB and the average indirect economic burden caused by DALYs was 69.1 thousand RMB. ConclusionThere's heavy burden from AMES, and measures should be made to reduce the incidence and economic burden.
ObjectivesTo estimate the latest burden of disability adjusted life years (DALYs) for liver cancer in China and the long-term trend, and to make future prediction.MethodsBased on the visualization platform of Global Burden of Disease 2016, data on the DALYs for liver cancer in China was extracted. The very recent status in 2016 and the previous trend from 1990 to 2016 were described, using annualized rate of change (ARC). The burden from 2017 to 2050 was further predicted by combining the ARC and the Chinese population data projected by the United Nation.ResultsIn 2016, the total DALYs for liver cancer in China was estimated as 11 539 000 person years (accounting for 54.6% of the global burden), and years of life lost (YLLs) and years lived with disability (YLDs) contributed 98.9% and 1.1%, respectively. The age-standardized DALY rate was 844.1 per 100 000 (3.0 times of the global average) and the male-to-female ratio was 3.4. The DALY rate continuously increased from 1990–2016 (ARC=0.57%), particularly in recent 5 years (ARC=1.75%). Among the DALYs for all cancers, liver cancer contributed approximately 20% and constantly remained as the top 2 (ranking as the number one before year 2005). There were inverse trends in gender, with increasing in males and decreasing in females (ARC was 0.77% and –0.11%, respectively). Hepatitis B infection continually kept the leading cause of DALYs for liver cancer (accounting for nearly 57%), and the DALY rate was gradually increasing (ARC=0.43%). Although the peak age of DALY rate was stable at 65to 69 years, the peak age of the DALYs changed from 55 to 59 years in 1990 to 60 ~ 64 years in 2016. In 2050, the estimated DALYs for liver cancer in China will reach 14.37 million person years, 20.0% more than that in 2017.ConclusionsThe DALYs caused by liver cancer in China exceeds the overall burden of all other countries in the world, and accounts for 1/5 of DALYs for all cancers in local population. The burden in males has been continuously rising, and the leading cause remained unchanged as hepatitis B infection. With population aging, the DALYs for liver cancer in China will be incessant to increase, suggesting the necessity to implement continuous effort in risk factors prevention (e.g. hepatitis B infection), and efficient management in high risk population of liver cancer.
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 variation trend of high low density lipoprotein cholesterol (LDL-C) attribution disease burden in China from 1990 to 2019. MethodsThe burden of disease indicators from Global Burden of Disease 2019 (GBD 2019), such as death attributable to high LDL-C, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lost to disability (YLDs) were extracted. The age was standardized using GBD 2019 global standard population, and the trend of rates with the annual percentage change (APC) was analyzed. ResultsFrom 1990 to 2019, the disease burden of high LDL-C increased with age in China. The mortality rate, DALYs rate and YLLs rate of males were higher than those of females, while the YLDs rate of males was lower than that of females. Joinpoint regression results showed that from 1990 to 2019, the high LDL-C attribution mortality rate (APC=3.4%, P<0.05), DALYs rate (APC=2.4%, P<0.05), YLLs rate (APC=2.4%, P<0.05), YLDs rate (APC = 2.9%, P<0.05), the standardized mortality rate (APC=0.8%, P<0.05) and the standardized YLDs rate (APC=0.7%, P<0.05) all increased in China. Regarding age, the mortality rate, DALYs rate and YLLs rate increased in the age group over 70 years old, while the YLDs rate increased significantly in the age group over 45 years old. ConclusionFrom 1990 to 2019, the burden of disease attributable to high LDL-C in China has become increasingly heavy, and the burden varies according to gender and age.
Objective To systematically review the epidemic trend and disease burden of ischemic stroke in the Chinese population and to provide references for formulating reasonable prevention and treatment measures and allocating health resources. Methods Based on Global Burden of Disease (GBD) data, we analyzed the morbidity, mortality, disability-adjusted life year (DALY) and normalized rates for ischemic stroke in China from 1990 to 2019 and evaluated the changes in the disease burden by sex and age group. Meanwhile, joinpoint regression model was constructed to analyze the time trend change in each stage during the study period. Results Compared with 1990, the incidence, mortality and DALY rate of ischemic stroke in China increased by 171.68%, 125.60% and 98.60% in 2019, among which the incidence, mortality and DALY rate of males increased by 184.29%, 148.96% and 115.16%, respectively; the morbidity, mortality and DALY rates of females increased by 160.9%, 101.32% and 81.44%, respectively. The age-standardized incidence increased by 34.70%, while the age-standardized mortality and age-standardized DALY rate decreased by 3.33% and 4.02%, respectively; the age-standardized incidence, mortality and DALY rates of males increased by 39.52%, 8.03% and 3.68%, respectively; the age-standardized incidence rate of females increased by 31.40%, while the age-standardized mortality rate and age-standardized DALY rate decreased by 14.02% and 11.53%, respectively. In 2019, both the mortality rate and DALY rate due to ischemic stroke increased with age, and the highest rate was found in the population over 85 years old. Males over 60 years old were significantly than females. In the 55-84 age group, the incidence of ischemic stroke in females was higher than that in males, while in the 85 and above age group, the incidence of ischemic stroke in females was lower than that in males. The AAPC of age-standardized incidence, age-standardized mortality, and age-standardized DALY rates due to ischemic stroke from 1990 to 2019 were 1.06% (95%CI 1.00% to 1.11%), 0.01% (95%CI −0.45% to 0.48%) and −0.16% (95%CI −0.53% to 0.22%), respectively. All indicators of the AAPC for males were higher than those for females. ConclusionThe curvent age-standardized mortality and DALY rate of ischemic stroke in China have decreased slightly compared with 1990. The crude mortality, morbidity and disease burden have significantly increased. All indicators of the AAPC for males were higher than those for females. To reduce the epidemic trend and disease burden of ischemic stroke, reasonable prevention and treatment measures and rational allocation of health resources should be made according to sex and age.
