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.
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.
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.
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.
ObjectiveTo analyze the trends of incidence, mortality, and burden of disease of cervical cancer in Chinese females from 1990 to 2019.MethodsThe global burden of disease database (GBD) and China health statistics yearbook data was used to analyze the incidence, standardized incidence, mortality, standardized mortality, urban and rural mortality, and burden of cervical cancer among Chinese females using Excel, SPSS 21.0 and Joinpoint Regression Program 4.8.0.1.ResultsThe standardized incidence of cervical cancer among Chinese females increased from 9.21/100 000 in 1990 to 12.06/100 000 in 2019, and the standardized mortality decreased from 8.40/100 000 to 7.36/100 000. The standardized mortality of cervical cancer in 2018 decreased when compared with 2015 in both urban and rural areas. Changes in age-group incidence and mortality indicated that there was a younger trend in cervical cancer. The disease burden indicators (DALY, YLL, and YLD) were increased from 86.49, 84.01, and 1.52 ten thousand person/years to 162.22, 157.40, and 4.83 ten thousand person/years, in which the YLD increased the most (217.76%). The APC of DALY, YLL and YLD were 2.39%, 2.56% and 4.25%, respectively. The proportion of cervical cancer disease burden in female cancer increased in 2019 compared with 1990. And DALY, YLL and YLD increased in the age group of 40 or over, in which DALY of the age group 50-54 increased 167.15%.ConclusionsThe situation of cervical cancer is not optimistic in China. Although the mortality of cervical cancer has decreased in recent years, the number of cases and mortalities is still increasing. Not only the burden of disease is continuously increasing, there is also a younger trend in cervical cancer. Active preventive measures should be taken to reduce the burden of cervical cancer.
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.
Clarifying the burden of disease is of great significance for determining the focus of healthcare and optimizing the allocation of medical resources. However, differences in research methods and assumptions often affect the comparability of different research results, thus leading to difficulties in healthcare decision-making. Disability-adjusted life year (DALY) is the most commonly used indicator to measure the burden of disease, but the reporting quality of disease burden studies using the DALY metric is uneven. To standardize the reporting of such studies, international scholars developed and recently published the STROBOD statement in Population Health Metrics. Its checklist includes seven parts: title, abstract, introduction, methods, results, discussion, and open science, involving a total of 28 items. To assist domestic scholars in better understanding and applying this reporting standard, this article interprets each item with published examples, aiming to improve the overall quality of disease burden research and provide high-quality evidence for public health decision-making.
ObjectiveTo analyze the changing trends in disease burden of femoral fractures in China from 1990 to 2021, evaluate the impacts of age, period, and cohort effects, and project the age-standardized prevalence rate and age-standardized incidence rates of femoral fractures from 2022 to 2036. MethodsUtilizing open data from the 2021 Global Burden of Disease (GBD) study, this research characterized the disease burden of femoral fractures in China between 1990 and 2021, including trends in incidence, prevalence, and years lived with disability (YLDs). Age-standardized rates were calculated, and Joinpoint regression models were employed to estimate annual percentage changes (APC) and average annual percentage changes (AAPC). An age-period-cohort (APC) model was applied to quantify the effects of age, period, and birth cohort on disease burden. A Bayesian age-period-cohort (BAPC) model was further utilized to project age-standardized prevalence rates and age-standardized incidence rates from 2022 to 2036, with stratified analyses by age, sex, and time period. ResultsFrom 1990 to 2021, age-standardized prevalence (AAPC=0.138 5%), incidence (AAPC=0.294 2%), and YLD rates (AAPC=0.128 3%) exhibited sustained upward trends. Unintentional injuries constituted the predominant etiology of femoral fractures, followed by transport accidents and interpersonal violence/self-harm. In 2021, disease burden escalated with advancing age, with females over 60 years demonstrating significantly higher burdens than males. Age effect coefficients showed a monotonic increase, period effects displayed a U-shaped trajectory (decline followed by rebound), and cohort effects exhibited an inverted U-shaped pattern (rise then decline). Projections indicated continued growth in age-standardized prevalence rates and age-standardized incidence rates through 2036. ConclusionAs the population aging intensifies in China, the disease burden of femoral fractures in our country remains extremely severe. Among them, the elderly female group has become the key focus for prevention and control due to the high prevalence of osteoporosis.
