Objective To analyze the disease burden of type 2 diabetes mellitus(T2DM)attributable to high body mass index(BMI)in China from 1990 to 2019 in the context of rapid growth in high BMI rates.Methods Data was extracted from GBD 2019,and the disease burden of T2DM attributable to high BMI in China from 1990 to 2019 was analyzed for overall and subgroups defined by age and sex separately and jointly.The joinpoint regression models were used to analyze the trends of standardized death rate and standardized disability-adjusted life year(DALY)rate.Results From 1990 to 2019,the prevalence of T2DM increased from 2928.78 per 100000 to 6328.79 per 100000 in China.The number of T2DM deaths attributed to high BMI increased from 10500 to 47500 and the standardized death rate increased from 1.25 per 100000 to 2.39 per 100000.The attributed DALY increased from 771800 person-years to 3737600 person-years,and the standardized DALY rate increased from 80.21 per 100000 to 181.54 per 100000.Years of life lost(YLL)and years lived with disability(YLD)and their standardized rates also increased.From 1990 to 2019,the annual average percentage change of the standardized death rate and the standardized DALY rate of T2DM attributable to high BMI were 2.28%and 2.81%,respectively,which were statistically significant(P<0.05)and males were both higher than females.The standardized DALY rate and the standardized death rate of males exceeded that of females in 2010 and 2014,respectively.Age-stratified results showed that the burden of T2DM,which is attributed to a high BMI,is even greater in people over 50 years old.The YLD rate attributable to high BMI increased the most among the 15～49 age group,reaching 323.99%.Conclusion From 1990 to 2019,the disease burden of T2DM that can be attributed to high BMI increased significantly in China.It is necessary to strengthen prevention and control efforts,effectively manage population BMI,and adopt key interventions for high-risk groups to reduce the disease burden of T2DM.

Burden and Trend of Cardiovascular Diseases Attributed to Household Air Pollution in the World and China From 1990 to 2019 / 中国循环杂志

Objectives:To explore the burden and trend of cardiovascular diseases(CVD)attributed to household air pollution(HAP)in the world and China from 1990 to 2019. Methods:Based on the Global Burden of Disease(GDB)database in 2019,the CVD data attributed to HAP in China and around the world were extracted,and the mortality and disability-adjusted life years(DALY)and their age standardized rate(ASR)and estimated annual percentage change(EAPC)were used to analyze the burden of disease and trend in China and other regions and countries from 1990 to 2019. Results:From 1990 to 2019,the age-standardized death rate(ASDR)(EAPC=-3.65,95%CI:-3.86 to-3.44),and the age-standardized DALY rate(EAPC=-3.60,95%CI:-3.78 to-3.41)attributable to HAP for CVD globally showed a decreasing trend.In China,the ASDR(EAPC=-5.78,95%CI:-6.17 to-5.38)and the age-standardized DALY rate(EAPC=-5.97,95%CI:-6.32 to-5.62)also showed a declining trend.The burden of males was slightly higher than females,reaching its peak at the age of 75 to 89 years.The largest increase of the burden of CVD attributed to HAP was in Philippines(ASDR:EAPC[95%CI]=0.87[0.21-1.54];age-standardized DALY rate:EAPC[95%CI]=1.32[0.60-2.03]),and the largest decline was in Saudi Arabia(ASDR:EAPC[95%CI]=-18.48[-18.63 to-18.32];age-standardized DALY rate:EAPC[95%CI]=-18.25[-18.38 to-18.12]).In 2019,the highest disease burden of CVD related to HAP per 100 000 people was significantly higher in ASDR(56.67,95%UI:42.08-73.07)and age-standardized DALY rate(1 318.63,95%UI:997.40-1 672.29)in areas with low social demographic index(SDI)than in other SDI areas.In 2019,among the 21 geographical regions and 204 countries in the world,the highest disease burden per 100 000 people was in Oceania,and the highest country was Solomon Islands,the corresponding ASDR of China was 12.52(95%UI:6.35-21.29)and the age-standardized DALY rate was 262.65(95%UI:133.90-447.50). Conclusions:From 1990 to 2019,the age-standardized burden of CVD attributable to HAP in the world and China showed a consistent downward trend,with males slightly higher than females,and the burden concentrated on population between 75 and 89 years old.Although there has been a certain decline in China,the disease burden is still high,so there is still a urgent need to take strong intervention measures to reduce burden of CVD attributable to HAP in China.

Analysis and model prediction of the burden of HIV/AIDS among the population aged 10-49 in four different SDI countries in 1990 - 2019 / 公共卫生与预防医学

Objective To understand the HIV/AIDS burden and the disease burden attributed to various risk factors in four countries with different socio-demographic index (SDI) (China, United States, Russia, and Afghanistan) from 1990 to 2019, and to predict the HIV/AIDS attributable disease burden from 2020 to 2029. Methods The 2019 Global Burden of Disease Study data was used to describe and compare the incidence, prevalence, death, and DALYs of HIV/AIDS in the four countries. The standardized DALYs attributed to various risk factors in different age groups of HIV/AIDS in the four countries in 1990 and 2019 were compared. R4.3.0 was used to construct an autoregressive moving average mixed model to predict the attributable disease burden in each country over the next decade. Results Compared with 1990, in 2019, the standardized incidence rate, standardized prevalence rate, standardized mortality rate, and standardized DALYs rate in China and the other two countries, except the United States, showed an increase. People aged 10 to 49 years old were a key group for disease burden, and the main risk factors for disease burden varied among different countries and age groups. The autoregressive moving average mixed model predicted that the main risk factor for Russia in the next decade would be injecting drugs, while unsafe sexual behavior would occur in the other three countries. Conclusion There are differences in disease burden and risk factors among different genders and age groups globally and in the four different SDI countries. Therefore, differences should be fully considered to determine the focus of HIV/AIDS prevention and control and rationally allocate health resources.

Disease Burden of Esophageal Cancer Attributable to Smoking from 1990 to 2019 in China / 中山大学学报(医学科学版)

ObjectiveTo analyze the trends in the disease burden of esophageal cancer attributed to smoking in China from 1990 to 2019. MethodsUsing the Joinpoint 4.9.1.0 software， based on the Global Burden of Disease Study 2019 data， we examined the mortality， Disability-Adjusted Life Years （DALY） data， and death rates of esophageal cancer attributed to smoking in China from 1990 to 2019， along with national population data. The trends in disease burden was described and the age-period-cohort model was employed to analyze the effects of age， period， and cohort on the trends in disease burden due to smoking. ResultsJoinpoint analysis indicated that the age-standardized mortality rate （ASMR） and DALY rate attributable to smoking showed an average annual percent change （AAPC） of -1.42% and -1.72%， respectively. For females， the AAPC values for ASMR and DALY rate were -3.26% and -3.70%， respectively， while for males， these were -1.28% and -1.54%， respectively. The disease burden by age attributable to smoking showed a general declining trend across all age groups in mortality and DALY rates. The disease burden from smoking， measured by age， displayed a consistent downward trend in both mortality and DALY rates across all age groups. The 40-44 age group saw the sharpest decline， with Annual Average Percent Changes （AAPC） of -3.05% for mortality and -3.04% for DALY rates. This was closely followed by the 45-49 age group， which experienced AAPC values of -2.73% and -2.72%， respectively. Analysis using the age-period-cohort model showed that the impact of age on mortality and DALY rates due to smoking initially increases with age before subsequently decreasing. The period effect revealed a general increase in the mortality rate from smoking in China， except for a dip between 2005 and 2010； otherwise， the trend was upward over time. The DALY rate demonstrated variability across different periods. The cohort effect indicated a decrease in both mortality and DALY rates due to smoking as successive birth cohorts progressed. ConclusionsOur study reveals that the disease burden of esophageal cancer attributed to smoking factors exhibits gender differences and shows an overall declining trend over time. Efforts should be intensified to enhance health education for men， particularly focusing on smoking cessation education for smokers aged 35-39， in order to improve the overall level of primary prevention of esophageal cancer.

Disease Burden and Indirect Economic Burden Due to Lung Cancer from 1981 to 2020 in Kunshan, Jiangsu Province, China / 肿瘤防治研究

Objective To identify the disease burden and indirect economic burden caused by lung cancer in Kunshan City, Jiangsu Province, from 1981 to 2020. Methods The incidence and death cases of lung cancer were obtained from cancer registry and death cause monitoring data. The disability adjusted life years (DALY) was used as the evaluation index for burden posed by lung cancer on health, and the indirect economic burden was calculated by a human capital method. Results From 1981 to 2020, a total of 9272 deaths due to lung cancer were reported in Kunshan, of which 7106 were males and 2166 were females. The DALY caused by lung cancer in the whole population were 3.81, 4.14, 4.38, and 9.46 in 1981–1990, 1991–2000, 2001–2010, and 2011–2020, respectively. The indirect economic burden caused by lung cancer was 10.515, 141.657, 813.794, and 6659.149 million yuan. From 2011 to 2020, the ratios of years of life lost due to premature mortality to DALY in males, females, and the general population were 92.42%, 95.15%, and 93.60%, respectively. Conclusion The health burden and indirect economic burden for lung cancer are substantial in the Kunshan City. Moreover, age-specific DALY and indirect economic burden are not exactly symmetrical, suggesting that an effective control strategy to lower cost is urgently needed, especially for individuals aged 40-59.

Trends in prevalence and disability-adjusted life years of cataract in China from 1990 to 2019 / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To assess the evolving burden of cataracts in China from 1990 to 2019.METHODS: Data on disease burden related to cataracts in China were retrieved from the Global Burden of Disease(GBD)2019 study based on large public databases. Utilizing data from the GBD 2019 study, we extracted information on cataract-related disease burden in China from extensive public databases. Analysis of prevalence and disability-adjusted life years(DALYs)associated with cataracts in China was conducted based on GBD 2019 findings. The variable characteristics of age-standardized prevalence rates(ASPR)and age-standardized DALYs rates(ASDR)in China and its neighboring countries were also explored.RESULTS: Between 1990 and 2019, the number of prevalent cases of blindness and vision loss caused by cataracts in China increased by 223.54%, and the corresponding DALYs raised by 142.14%. Over the past 30 years, females exhibited higher age-standardized prevalence and DALYs rates compared to males. Meanwhile, individuals aged 65 to 84 years were found to be more susceptible to cataracts than other age groups. Compared with neighboring countries, China ranked from the 9th position in 1990(867.09, 95%UI: 761.36 to 975.42, per 100 000 population)to the 11th in 2019(991.56, 95%UI: 861.52 to 1131.04, per 100 000 population)in ASPR, while from the 9th in 1990(65.85, 95%UI: 46.39 to 89.41, per 100 000 population)to the 10th position in 2019(59.16, 95%UI: 41.70 to 80.15, per 100 000 population)in ASDR. However, on a global scale, China maintained relatively low ASDR and ASPR for cataracts in 2019.CONCLUSION: The study highlights a substantial rise in the prevalence and DALYs associated with blindness and vision loss due to cataracts from 1990 to 2019 in China, and underscores the urgent need for increased early screening of cataracts, particularly among the elderly and females.

Objective To analyze the data of prostate cancer in Wuhan from 2010 to 2019, understand the characteristics and trends of incidence, mortality, and YLL, and provide decision-making basis for Wuhan's cancer prevention and control strategies. Methods Data on deaths and incident cases of prostate cancer in Wuhan from 2010 to 2019 and from 2013 to 2017, respectively, were collected from the Wuhan Death Monitoring System. Indicators such as incidence rate, mortality rate, and years of life lost due to premature death (YLL) of prostate cancer in Wuhan were calculated using Excel 2016 and Python. The Bayesian Age-Period-Cohort Model (BAPC) was used to predict the mortality rate of prostate cancer in Wuhan from 2020 to 2024. The trend changes were described using the annual average percentage change (AAPC). Results From 2010 to 2019, the incidence, mortality, and YLL rates of prostate cancer in Wuhan showed an overall increasing trend (AAPC >0, P <0.05). The standardized mortality and incidence rates in the central urban area were significantly higher than those in the outer urban area, and the age group of 85 and above had the highest incidence and mortality rates. The age group of 0-54 had the largest increase in incidence and mortality rates. From 2020 to 2024, prostate cancer in Wuhan is expected to continue to increase slightly (an increase of 0.94%). Conclusion The incidence, mortality, and YLL rates of prostate cancer in Wuhan are showing an overall increasing trend, and this trend may continue. The characteristics are higher in the central urban area than in the outer urban area, and higher in the older age group than in the younger age group. Targeted measures need to be taken, and screening for high-risk populations should be strengthened.

Global Burden of Cardiovascular Disease Attributable to High Temperature in 204 Countries and Territories from 1990 to 2019 / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to estimate spatiotemporal variations of global heat-related cardiovascular disease (CVD) burden from 1990 to 2019.@*METHODS@#Data on the burden of heat-related CVD were derived from the Global Burden of Disease Study 2019. Deaths and disability-adjusted life years (DALYs) were used to quantify heat-induced CVD burden. We calculated the age-standardized mortality rate (ASMR) and DALY rate (ASDR) per 100,000 population to compare this burden across regions. Generalized linear models were applied to evaluate estimated annual percentage changes (EAPC) for temporal trends from 1990 to 2019. The correlation between the socio-demographic index (SDI) and age-standardized rate was measured using the Spearman rank test.@*RESULTS@#Heat-induced CVD caused approximately 90 thousand deaths worldwide in 2019. Global ASMR and ASDR of heat-related CVD in 2019 were 1.17 [95% confidence interval ( CI): 0.13-1.98] and 25.59 (95% CI: 2.07-44.17) per 100,000 population, respectively. The burden was significantly increased in middle and low-SDI regions and slightly decreased in high-SDI regions from 1990 to 2019. ASMR showed an upward trend, with the most considerable increase in low-latitude countries. We observed a negative correlation between SDI and EAPC in ASMR ( r s = -0.57, P < 0.01) and ASDR ( r s = -0.59, P < 0.01) among 204 countries.@*CONCLUSION@#Heat-attributable CVD burden substantially increased in most developing countries and tropical regions.

Objective:To explore the changes of disease burden and risk factors of chronic kidney disease (CKD) due to type 1 and type 2 diabetes mellitus in China from 1990 to 2019, and to provide reference data for the prevention and control of diabetic kidney disease (DKD).Methods:The Chinese DKD data were obtained from the 2019 Global Burden of Disease (GBD) database. The morbidity, prevalence, mortality, years lived with disability (YLD), years of life lost (YLL), and disability-adjusted life year (DALY) were used to compare the disease burden of CKD due to type 1 and type 2 diabetes mellitus from 1990 to 2019. In addition, the risk factors of DKD were analyzed.Results:The numbers of CKD patients due to type 1 and type 2 diabetes mellitus in China were 574 (95% UI 495-665) and 31 076 (95% UI 28 152-33 909) thousand, and the numbers of new cases were 9 (95% UI 8-11) and 434 (95% UI 390-481) thousand in 2019, respectively. The numbers of death were 13 (95% UI 8-18) and 63 (95% UI 50-77) thousand, respectively. The age groups with the largest number of patients and new cases of CKD due to type 1 diabetes mellitus were 30-34 years old and <5 years old, respectively. The age group with the largest number of patients and new cases of CKD due to type 2 diabetes mellitus were 50-54 years old and 70-74 years old, respectively. From 1990 to 2019, the age-standardized prevalence rate of DKD patients in China was relatively stable, but the age-standardized incidence rate and YLD rate showed an upward trend, while the age-standardized mortality rate, YLL rate, and DALY rate showed a downward trend. The main risk factors associated with DKD death were high fasting plasma glucose, kidney dysfunction, high systolic blood pressure, high body mass index, high sodium diet, and lead exposure. The proportions of DKD death caused by high systolic blood pressure and high body mass index in the Chinese population were still increasing. Conclusions:From 1990 to 2019, the age-standardized incidence and YLD rate of DKD in China shows an upward trend, while the age-standardized prevalence rate is relatively stable, and the age-standardized mortality rate, YLL rate, and DALY rate show a decreasing trend. High fasting glucose, renal failure, high systolic blood pressure, high body mass index, high sodium diet, and lead exposure are risk factors associated with death in DKD patients. With the progress of aging, the disease burden of DKD in China will continuously increase. Future work should be focused on population-specific interventions, taking into consideration the risk factors identified within the study.

Changes in the disease burden of liver cancer caused by nonalcoholic steatohepatitis in China 1990-2019 / 公共卫生与预防医学

Objective To describe and analyze the disease burden and its changing trend of liver cancer caused by nonalcoholic steatohepatitis (NASH) in China from 1990 to 2019, and to provide reference for reducing the morbidity and mortality of liver cancer in China. Methods Based on data from the Global Burden of Disease (GBD2019) study, different gender and age groups were selected. The morbidity, mortality, and disability adjusted life year (DALY) rate were used to analyze the disease burden of liver cancer caused by NASH in China from 1990 to 2019. The time trend was analyzed by using the Joinpoint regression model, and the annual percent of change (APC) and annual average percentage change (AAPC) of morbidity, mortality and DALY rate were calculated. Results Compared with 1990, the incidence rate, mortality rate and DALY rate of liver cancer caused by NASH in 2019 decreased by 4.05%, 12% and 25.79%, respectively. Age-standardized morbidity, standardized mortality and standardized DALY rates decreased by 49.50%, 54.72% and 58.45%, respectively. In 2019, the incidence rate, mortality data and DALY rate of liver cancer caused by NASH increased with age, and the highest mortality rate was among people over 85 years old. The average annual change percentage (AAPC) of age-standardized incidence rate, standardized mortality rate and standardized DALY rate of liver cancer caused by NASH from 1990 to 2019 were -2.65% ［95% CI（-3.09%，-2.21 %），P<0.001］, -2.86%［95% CI（-3.34%，-2.38 %），P<0.001］, and -2.91%［95% CI（-3.23%，-2.58%），P<0.001］，respectively. The AAPC of all indexes in males was higher than that in females. Conclusion From 1990 to 2019, the disease burden of liver cancer caused by NASH in China showed an overall downward trend. The AAPC of all indexes in males is higher than that in females, and the elderly population is a high-risk group.

Current status changing trend and influencing factors of pancreatic cancer disease burden in Chengde of Hebei Province in 2010 - 2020 / 公共卫生与预防医学

Objective To analyze the disease burden status, trends and possible influencing factors of pancreatic cancer in Chengde of Hebei from 2010 to 2020, in order to provide theoretical basis for the preventionof pancreatic cancer. Methods Using the global burden of disease open database, the incidence rate, mortality, years of life lost (YLL), years of life lost with disability (YLD) and disability adjusted life year (DALY) of pancreatic cancer in the region are obtained,average annual percent change (AAPC) was calculated using joinpoint model to test the trend of disease burden change of pancreatic cancer patients from 2010 to 2020. At the same time, the patient characteristics such as hypertension, diabetes and other categorical variables were set as dummy variables, and the risk factors affecting the mortality of patients with pancreatic cancer were analyzed by linear regression. Results In 2010, there were 15 new cases of pancreatic cancer and 13 deaths in Chengde District , Hebei Province. The YLLs caused by pancreatic cancer accounted for 70.67% of DALY. In 2020, there were 160 new cases of pancreatic cancer and 147 deaths in Chengde, Hebei Province. The YLLs caused by pancreatic cancer accounted for 96.02% of DALY. From 2010 to 2020, the incidence of pancreatic cancer increased by 9.79%, and the incidence rate increased by 7.81%, showing an obvious upward trend (APCC =2.20%, P 28.0 and pancreatitis (OR=1.574 , 95% CI: 1.328-3.045) were all risk factors for death of patients with pancreatic cancer (OR>1) . Conclusion From 2010 to 2020, the incidence and mortality of pancreatic cancer among local residents in Chengde of Hebei showed an upward trend, and the disease burden was also increasing year by year. The basic diseases of diabetes and chronic pancreatitis increase the death risk and should be protected.
