ObjectiveTo analyze the burden of digestive diseases attributed to smoking in China from 1990 to 2019 and forecast its change in the next 10 years. MethodsThe Global Burden of Disease database 2019 was used to analyze the burden of digestive diseases attributed to smoking in China from 1990 to 2019. Joinpoint regression model was used to analyze the time variation trend. A time series model was used to predict the burden of digestive diseases attributable to smoking over the next 10 years. ResultsIn 2019, there were 12 900 deaths from digestive diseases attributed to smoking in China, with a DALY of 398 600 years, a crude death rate of 0.91/100 000 and a crude DALY rate of 28.02/100 000. The attributed standardized mortality rate was 0.69 per 100 000, and the standardized DALY rate was 19.79 per 100 000, which was higher than the global level. In 2019, the standardized mortality rate and DALY rate of males were higher than those of females (1.48/ 100 000 vs. 0.11/ 100 000, 38.42/ 100 000 vs. 293/100 000), and the standardized rates of males and females showed a downward trend over time. In 2019, both mortality and DALY rates from digestive diseases attributed to smoking increased with age. ARIMA predicts that over the next 10 years, the burden of disease in the digestive system caused by smoking will decrease significantly. ConclusionFrom 1990 to 2019, the burden of digestive diseases attributed to smoking showed a decreasing trend in China, and the problem of disease burden is more serious in men and the elderly population. A series of effective measures should be taken to reduce the smoking rate in key groups. The burden of digestive diseases caused by smoking will be significantly reduced in the next 10 years.
ObjectivesTo systematically review approaches to derive disability weights (DWs) based on EQ-5D instrument.MethodsPubMed, EMbase, Web of Science, CNKI and WanFang Data databases were electronically searched to collect studies on the approaches to derive disability weights based on EQ-5D from inception to June 1st, 2019. Two reviewers independently screened literature, extracted the basic information and evaluated risk of bias of included studies. Then, systematic review on approaches to derive DWs based on EQ-5D instrument was performed.ResultsA total of 18 studies were included, which were published between 2003 and 2018. The included studies involved a variety of diseases, mostly focusing on quality of life and the burden of disease. The approaches to derive DWs based on EQ-5D health instrument were as follows: DWs=health utility scoreNormal or Control−health utility scoreDisease (7 studies), DWs=1−VAS score/100 (6 studies), DWs=1−health utility scoreDisease (3 studies), linear regression model (1 study), and mapping (1 study).ConclusionsAmong all the included studies using EQ-5D-based disability weight measurement methods involves a variety of diseases, with relatively low comparability. More methodological studies are from abroad. Among all the applied approaches, DWs equally to health utility scoreNormal or Control minus health utility scoreDisease is the most commonly used.
ObjectiveTo analyze the epidemiological burden and trend of skin malignant melanoma in China based on the data from the global burden of disease 2019 (GBD 2019). MethodsThe data about quantity of incidences/illnesses/deaths, age-standardized incidence/prevalence rates/mortality, disability-adjusted life years (DALYs), and DALY rate of skin malignant melanoma in China from 1990 to 2019 were obtained from the GBD 2019 databases. The epidemiological trends, age-period-cohort trends, and the relationship between the incidence and sociodemographic index (SDI) were analyzed.ResultsIn 2019, both prevalence and incidence of skin malignant melanoma in China were at low levels in the world, the age-standardized mortality ranked the 35th in the 204 countries GBD researched, the number of prevalent cases and incident cases increased compared with 1990 (12.65% and 3.57%, respectively), the prevalence and incidence rates showed growth trends, while the DALY rate and mortality decreased slowly. The prevalence of skin malignant melanoma peaked age at 50 to 54 years old. The incidence peak age of males was older than that of females (55-59 years old for males vs. 50-54 years old for females), while the mortality peak age of males was younger than that of females (55-59 years old for males vs. 75-79 years old for females). With the increasing of SDI value, the incidence of skin malignant melanoma showed a linear growth trend. DALY rate was negatively correlated with SDI (P<0.05). ConclusionFrom 1990 to 2019, age-standardized incidence and prevalence of skin malignant melanoma in China are increasing, while DALY rate and mortality are decreasing, and these are correlated with social and medical development.
ObjectiveTo analyze the trend of disease burden of colorectal cancer (CRC) in China from 1990 to 2019.MethodsData was obtained from Global Burden of Disease Study 2019 (GBD 2019). Incidence, mortality, disability-adjusted life year (DALY), years of life lost (YLL), years lived with disability (YLD), and their corresponding standardized rate and annual average percentage change (AAPC) were used to describe the changes of disease burden of colorectal cancer in Chinese population between 1990 and 2019.ResultsCompared with 1990, the number of new cases, standardized incidence, the number of deaths and standardized mortality of CRC in China in 2019 increased by 474.03%, 144.01%, 230.14%, and 36.15%, respectively. The standardized mortality and standardized incidence of CRC in China had reached and gradually exceeded the global level since 2010. From 1990 to 2019, the overall standard incidence (AAPC=3.6%, P<0.05), standard mortality rate (AAPC=1.4%, P<0.05), and the standard DALY rate (AAPC=1.2%, P<0.05) of CRC in China showed an increasing trend. The incidence, mortality and DALY rates of males were higher than those of females, and gradually increased with age. Compared with 1990, the DALY, YLL, and YLD of CRC in 2019 increased by 134.3%, 127.69%, and 445.00%, and their corresponding standardized rates increased by 30.53%, 27.03%, and 187.29%, respectively, showing an overall upward trend.ConclusionsFrom 1990 to 2019, the standardized incidence rate and standardized mortality rate of colorectal cancer in China have had a continuously increasing trend, and males and the elderly are high-risk groups. To reduce the burden of colorectal cancer in China, effective measures should be taken for prevention and management.
ObjectiveTo estimate the level and evolving pattern of peptic ulcer disease (PUD) burden from 1990 to 2019. MethodsThe related data of PUD from 1990 to 2019 were obtained from GBD 2019 database. The corresponding age-standardized rate, annual percentage change, average annual percentage change were calculated and analyzed by Excel and R software. ResultsThe global standardized prevalence of PUD was 99.4/100 000 (95%CI 83.9 to 117.5) in 2019, and decreased from 143.4/100 000 (95%CI 120.5 to 170.2) in 1990. The standardized disability-adjusted disease years (DALYs) rate was 74.4 (95%CI 69.0 to 81.9) in 2019. The estimated annual percentage change (EAPC) from 1990 to 2019 was −3.47% (95%CI −3.58 to −3.37), indicating that the standardized DALYs rate was declining. The prevalence and DALYs of PUD increased with age. The standardized DALYs rate was higher in males than in females in the same age group. Sociodemographic index (SDI) was negatively correlated with the standardized prevalence of PUD (R=−0.45, P<2.2e−16) and the standardized DALYs rate (R=−0.79, P<2.2e−16). ConclusionThe worldwide burden of PUD declined from 1990 to 2019, but the decline had begun to slow or pause in countries with better economic development levels.
Objective To assess the methodological quality of systematic reviews/ meta-analysis of burden of illness, analyses the factors affecting it, so as to provide a reference basis for improving the methodological quality of related studies. Methods Systematic reviews/ meta-analysis of burden of illness were identified in PubMed, searching from its inception to 12 October 2024. Systematic reviews/ meta-analysis of burden of illness was included, the methodological quality of the included literature was evaluated using AMSTAR-2, and data were extracted using Excel 2021. Results A total of 308 systematic reviews/ meta-analysis were included, with a fluctuating upward trend in the number of publications from 2006 to 2024; of these, a total of 12 were rated as low quality. According to the AMSTAR-2 entries, the largest number of documents fully conformed to entry 16 (82.14%), followed by entry 5 (81.49%), and entry 8 (72.73%); one document conformed to entry 10 (0.32%), and relatively few conformed to entry 12 (68.83%), entry 13 (85.39%), and entry 15 (67.53%). ConclusionThe methodological quality of systematic reviews/ meta-analysis of burden of illness needs to be improved, and the main problems include the lack of pre-study protocols, the absence of a list of excluded literature, and the less than adequate explanation of heterogeneity and risk of bias, etc. There is still a need to further improve the methodological quality of the systematic reviews and to promote the long-term development of evidence based medicine.
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.
Objective The Global Burden of Diseases (GBD) data were used to analyze the trend of the burden of disease of tracheal, bronchial, and lung cancer (TBL Cancer) caused by tobacco in China and globally from 1990 to 2021, and to predict the future development trend. Methods We performed descriptive analysis of the indicators of death and disability-adjusted life years (DALY) in the GBD 2021 database; The Joinpoint regression model was used to calculate the average annual percent change (APCC); The age-period-cohort (APC) model was used to estimate the effect of three independent factors, age, period and cohort, on disease mortality; and the BAPC model was used to project the burden of disease for TBL Cancer from 2022 to 2036. Results From 1990 to 2021, the disease burden of TBL Cancer attributable to tobacco showed an increasing trend in both China and globally, with a much higher burden of disease in men than in women, and a much higher burden of disease attributable to smoking than to secondhand smoke. The APC model showed that the net drift values of mortality in China and globally were −0.1982% and −1.5921%, respectively, from 1992 to 2021; the age effect showed that the mortality rate of both China and the world increased with age; the period effect model showed that the mortality rate of China increased and then decreased, and the global mortality rate generally decreased; the cohort model showed that the mortality rate of China and the world increased and then decreased; the BAPC model showed that the mortality rate of China declined slowly in the period of 2022-2036, and the global mortality rate declined even more dramatically. Conclusion The burden of TBL Cancer attributable to tobacco was higher in China than in the world from 1990 to 2021. Tobacco control measures in China have begun to bear fruit in recent years, and we should continue to strengthen our tobacco control initiatives and popularize health knowledge in order to make progress towards the goal of the "Healthy China 2030" plan.
ObjectivesTo systematically review the disease burden of osteoporotic fracture (OPF) in China.MethodsWe searched PubMed, EMbase, CNKI, WanFang Data and VIP database for observational studies of the disease burden of osteoporosis in China from inception to Jan 30th, 2018. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies.The descriptive analysis was used to analyze the economic burden of OPF in China.ResultsA total of 23 studies were included. The average cost of OPF was 27 561.27 yuan. Women were more prone to OPF than men. Hip and spinal fractures were the diseases which had higher average hospital costs.ConclusionsWomen are more prone to osteoporotic fractures than men. The higher hospital costs of OPF may cause the reason for growing financial burden of patients. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify conclusions.
Health technology assessment (HTA) is becoming more and more popular recently. For populations in China that share at least half of the global disease burden of liver cancer, it is extremely vital to give rise to an efficient secondary prevention strategy. The China central government launched liver cancer screening program in rural areas in 2005, and then extended to populations in urban in 2012. The studies of health technology assessment of liver cancer screening are based on available evidence, from an HTA perspective, aims to evaluate performance of liver screening, economic burden and cost-effectiveness and some other issues, in order to raise suggestions for possible directions in research and public health program related to liver cancer screening in China.
