ObjectiveThis study intends to analyze the changing disease burden of mood disorders in China from 1990 to 2021 and project the epidemiological trends in the next two decades. MethodsThis study uses data from the Global Burden of Disease (GBD) 2021 database on three mood disorders in China (bipolar disorder, major depressive disorder, and dysthymia) from 1990 to 2021. The indicators such as age-standardized number of diseases and disability-adjusted life years (DALYs) were used to explore the characteristics of time, gender, and age distribution of the disease burden of mental disorders. The BAPC model was used to predict the disease burden in the next two decades. ResultsIn 2021, the number of cases of dysthymia, MDD, and BD in China was 27.84 million, 26.0 million, and 2.85 million, with an increase of 73.24%, 38.33%, and 36.79% compared with 1990, respectively. In 2021, DALYs of dysthymic disorder, MDD and BD were 2.67 million, 5.2 million and 0.61 million person-years, which increased by 71.45%, 34.29% and 34.76% compared with 1990, respectively. The burden of mood disorders is heavier among women and the middle-aged and elderly population. In addition, it is expected that ASPR and ASDR of dysthymia will continue to increase after a brief decline, MDD will show a downward trend, while BD will show a slight upward trend in the next two decades. ConclusionThe disease burden of mood disorders in China remains substantial, with dysthymia and BD showing persistent upward tendency. More resources should be invested in mental health care.
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.
Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001）. In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.
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.
Objective To systematically review the incidence, mortality and disease burden of colorectal cancer (CRC) in China. Methods The CNKI, WanFang Data, VIP, CBM, PubMed, Embase and Web of Science databases were searched to collect cohort studies about the incidence, mortality and disease burden of CRC in China from the establishment of the database to July 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 18.0 software. Results A total of fifty-six studies were included. The result of meta-analysis showed that the overall incidence of CRC in China was 31‰ (95%CI 29‰ to 33‰), and the incidence of male was 35‰ (95%CI 32‰ to 37‰). The female incidence was 27‰ (95%CI 25‰ to 29‰). The overall mortality of CRC in China was 20‰ (95%CI 17‰ to 22‰), of which the male mortality was 22‰ (95%CI 19‰ to 25‰), and the female mortality was 18‰ (95%CI 15‰ to 20‰). Conclusion The incidence and mortality rates of CRC in China are high, resulting in a significant disease burden that varies regionally. The incidence and mortality of males are significantly higher than those of females. Intervention measures should be taken to reduce the disease burden of CRC in China according to the related risk factors of CRC.
ObjectiveTo analyze the trend of disease burden changes in congenital birth defects in China from 1990 to 2019. MethodsUsing the global burden of disease study 2019 (GBD 2019), we analyzed the morbidity, mortality, and disability-adjusted life years (DALYs) of congenital birth defect diseases and their corresponding age-standardized rates and average annual percentage change (AAPC) to analyze the changes in the disease burden of congenital birth defects in China and compared them with global data from 1990 to 2019. ResultsIn 2019, the age-standardized incidence, mortality, and DALY in China were 147.41/100 000, 4.62/100 000, 480.95/100 000, respectively. Compared with 1990, the age-standardized incidence rate, age-standardized mortality rate, and age-standardized DALY rate increased by 12.08% and decreased by 70.38% and 66.82%, respectively. In recent years, although the age-standardized incidence of congenital birth defect disease in China is on the rise and higher than the global level, the disease burden is roughly on the decline and lower than the global level, which is closely related to earlier intervention and treatment of the disease resulting in a lower standardized mortality rate. ConclusionThe age-standardized mortality rate of children with congenital birth defects in China showed a decreasing trend from 1990 to 2019, and the burden of disease ranged from slightly higher than global to lower than global levels, but the age-standardized incidence rate was significantly higher, but the age-specific incidence rate has increased significantly.
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.
In China, there are more than 2 million new strokes annually, and the disability-adjusted life-years due to stroke were higher than any other disease. With aging of the population, inadequate control of vascular risk factors such as hypertension, and uneven distribution of specialized stroke care, the burden of stroke will continue to increase. Despite improved health care quality in China, the availability of specialized stroke care varies across the country, especially in rural areas. Stroke prevention, management and research face unique and severe challenges due to rough terrain and economic underdevelopment in Southwest China. In the future, efforts should be made to provide more balanced availability of specialized stroke care services across China, promote generalization of evidence-based practice, and carry out more high-quality research to improve outcomes of stroke patients, with special attention to the rural population and Southwest China.
ObjectivesTo systematically review the prevalence and disease burden of knee osteoarthritis (KOA) in China.MethodsPubMed, EMbase, CNKI, WanFang Data and VIP databases were searched to collect cross-sectional studies about the prevalence and disease burden of KOA in China from January 1st 1995 to August 31st 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using R statistical software.ResultsA total of thirty-three studies were included. The results of meta-analysis showed the prevalance rate of KOA was 18% (95%CI 14% to 22%), and it was higher in women (19%, 95%CI 16% to 23%) than in men (11%, 95%CI 9% to 13%) (P<0.05). The prevalence rates of KOA in different regions were as follows: 11% (95%CI 8% to 14%) in north, 17% (95%CI 15% to 20%) in north-east, 21% (95%CI 13% to 32%) in east, 21% (95%CI 13% to 33%) in north-west, 22% (95%CI 6% to 57%) in south-west, and 18% (95%CI 13% to 23%) in south-central, respectively.ConclusionsThe prevalence of KOA in China is high, and the disease burden is heavy. Due to the quantity and quality of included studies, more high-quality studies are required to verify the above conclusions in future.
Objective To investigate the association between costs of hospitalized patients with diabetes mellitus and their complications in the West China Hospital of Sichuan University, so as to provide baseline data for further research. Methods We extracted the hospitalization case data of hospitalized patients with diabetes mellitus who were discharged from the department of endocrinology and metabolism, or discharged after being transferred to other departments for treatment from January 2011 to December 2012, using the hospital information system (HIS) of the West China Hospital of Sichuan University. The data included baseline of hospital patients, discharge diagnosis, hospitalization costs, and if their medical insurance had been registered in hospital. Then, we classified the diseases according to ICD-10 based on discharge diagnosis, coped the data using Excel 2010 software, and conducted statistical analysis using SPSS 13.0. Results a) In 2011, acute and chronic diabetes complication in diabetes inpatients were 11.9% (166/1 396) and 67.1% (930/1 396), respectively. Most of them had peripheral neuropathy and peripheral vascular disease. b) The most frequently-occurred complications were hypertension, followed by dyslipidemia, and osteoporosis. c) The median hospital stay was 13 days (7 to 9 days), and the median total cost of hospital/person-time was 6 578.88 yuan (4 186.93 to 10 953.89 yuan). d) The total cost and duration of hospitalization increased along with the increasing number of the chronic complications of diabetes. e) The diabetic foot patients were 255 person-times, the median duration of hospitalization was 18 days (13 to 29 days), and the median total cost of hospital/person-time was 16 672.19 yuan (10 903.93 to 28 530.37 yuan). Diabetes patients with foot complication had higher total costs and longer duration of hospitalization than those without foot complication. Conclusion Diabetes mellitus is one of the most important diseases in the department of endocrinology and metabolism, which is heavy disease burden. The costs of hospitalization and chronic complications are closely associated. Among these complications, diabetic foot is the heaviest disease burden.
