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.

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.

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.

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.

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.

Objective To compare and analyze the disease burden caused by drinking in China in 1990 and 2019. Methods The global disease burden database 2019 was used to analyze the attribution score (PAF), mortality, disability adjusted life year (DALY) and other indicators attributed to drinking in China in 1990 and 2019. The disease burden caused by alcohol consumption was compared between China and the world as well as different social demographic index (SDI) regions. Results From 1990 to 2019, the PAF attributed to drinking increased by 12.85%. The number of deaths attributed to drinking increased to 514 700, and the mortality increased to 36.18/100 000, while the DALY attributed to drinking increased to 17.2651 million person-years, and the DALY rate increased by 5.16%. The disease burden attributed to drinking was higher in men than that in women, and the attributable mortality and DALY rate in the elderly over 70 years old were higher than those in the young. From 1990 to 2019, the attributable disease burden of esophageal cancer was the highest in China, followed by colorectal cancer. Compared with the world and different SDI regions, China had the lowest standardized DALY rate attributed to drinking. Conclusion Drinking is one of the important risk factors for related diseases and cancers in China, and effective intervention measures should be taken for key populations.

Objective To analyze the burden of chronic kidney disease (CKD) attributable to metabolic factors in Jiangsu Province from 1990 to 2019, and to provide evidence for the formation and implementation of intervention policies. Methods Using data from Jiangsu Province from the 2019 Global Burden of Disease Study (GBD 2019), mortality and disability-adjusted life-years (DALYs) were selected as indicators for analysis and standardized with the age structure of the world standard population. The effects of three metabolic factors including high systolic blood pressure (SBP), high fasting glycaemic index (FPG) and high body mass index (BMI) on the disease burden of CKD were analyzed, and the attributable disease burden by gender and age was compared. Results The rank of the three attributable risk factors was high SBP, high FPG, and high BMI. Standardized mortality rates attributable to high SBP, high FPG, and high BMI all showed an overall upward trend from 1990 to 2019, with annual average percent changes (AAPCs) of 0.3%, 0.0%, and 2.8%, respectively. Age-standardized DALYs attributed to high SBP and high BMI showed increasing trends, with the AAPCs of 0.5% and 3.1% (both P＜0.05), respectively. There was no statistical significance of high FPG (P > 0.05). Mortality and disease burden attributed to high SBP both showed upward trends with increasing age. Age-standardized mortality and age-standardized DALYs attributed to high FPG peaked at 45-49 and 50-54 age-group, respectively. Both age-standardized mortality and age-standardized DALYs attributed to high BMI peaked at ages 60-64 age-group. Conclusion The trends of mortality and DALYs attributed to the three risk factors can reflect the changes of population structure and lifestyle in Jiangsu Province in the past 30 years to a certain extent. Early screening of population at high risk of CKD and targeted provision of health policies can reduce the mortality and disease burden of CKD.

AIM: To analyze the incidence and disease burden of foreign body in eyes in 1990 and 2019 of China.METHODS: Using the global burden of disease database in 2019, the incidence and disability adjusted life years(DALY)of foreign body in eyes in 1990 and 2019 of China were analyzed among the total population and different age groups of China.RESULTS: In 2019, the number of cases of foreign body in eyes in China was 11.2535 million, and the incidence was 79.12/10 000. The number and incidence of foreign body in eyes in 2019 decreased 12.87% and 27.49% respectively compared with those in 1990. In 2019, the DALY of foreign body in eyes in China was 181 200 person-years, and the DALY of foreign body in eyes in 2019 increased by 6.14% compared with 1990. In 2019, the age groups with the highest number of cases, incidence and DALY were all 20-54 years old, which were 8 012 600, 103.97/10 000 and 102 500 person-years, respectively. From 1990 to 2019, the incidence of foreign body in eyes in China showed a decreasing trend, average annual percentage change(AAPC)=-1.2%(95%CI: -1.8～-0.7, P&#x003C;0.05), and DALY rate also showed a decreasing trend, AAPC=-0.6%(95%CI:-2.1～0, P&#x003C;0.05). From 1990 to 2019, the incidence and DALY rate of foreign body in eyes in China and the World showed a downward trend. In 2019, the incidence and DALY rate of foreign body in eyes in China were significantly higher than those in the World and regions with different sociodemographic index(SDI).CONCLUSION: Although the incidence and DALY rates of foreign body in eyes in China have been decreasing in recent years, China has a large population base and the burden of foreign body in eyes is still large in the World. Active preventive measures should be taken to reduce the disease burden of foreign body in eyes.

Objective: To demonstrate the disease burden and epidemiological characteristics of colorectal cancer in different regions by analyzing the incidence and mortality data in China and worldwide in 2020. Methods: Estimation of the incidence and mortality data of colorectal cancer were obtained from the GLOBOCAN 2020 database. The incidence, death, age standardized incidence rate (ASIR) and age standardized mortality rate (ASMR) of colorectal cancer in China and 20 regions in the world were compared. The correlation between the Human Development Index (HDI) and ASIR/ASMR was analyzed. Results: In 2020, the number of new cases of colorectal cancer in the world reached 1 931 600, and the number of deaths reached 935 200. The incidence and mortality in all regions of the world continued to rise in the age group above 50 years old. The morbidity and mortality in male were higher than those in female. East Asia ranked the highest number of incidence cases and deaths in the world, which were 740 000 and 360 100 respectively. There were significant differences in incidence and mortality among regions in the world. The highest ASIR and ASMR were observed in Northern Europe (33.61/100 000) and Eastern Europe (14.53/100 000), whereas the lowest ASIR and ASMR were both observed in South-Central Asia (5.46/100 000 and 3.16/100 000). HDI had significant exponential relationship with ASIR (r(2)=0.59, P<0.001) and ASMR (r(2)=0.38, P<0.001). There were 555 500 new cases and 286 200 death cases of colorectal cancer in China, accounting for about 30% of the world and more than 75% of East Asia. The ASIR of China was 24.07/100 000, ranking at the medium level, while the ASMR was 12.07/100 000, ranking at the high level of world. Conclusion: The incidence and mortality of colorectal cancer are highly correlated with HDI. China is one of the countries with the heaviest disease burden of colorectal cancer in the world.

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.

OBJECTIVES@#Age-related macular degeneration (AMD) is one of the 3 major eye diseases recognized by WHO to prevent blindness, and which is the main cause of irreversible visual impairment in the elderly. This study aims to analyze the disease epidemiological burden, and provide a theoretical foundation for the prevention and control of AMD in China based on the data in global burden of disease (GBD) 2019.@*METHODS@#The prevalent cases/prevalence, disability-adjusted life year (DALYs)/DALY rate of AMD and socio-demographic index (SDI) for global and China were searched from the GBD 2019 database to analyze the epidemiological trend, age-period-gender trend of AMD in China from 1990 to 2019, and to evaluate the relations between the prevalence and SDI.@*RESULTS@#In 2019, the prevalence of AMD in China was at a high level in the world, and the number of prevalent cases were 1.93 times of that in 1990. The prevalence and DALY rates continued to rise. The age trend of AMD in China was high at the middle of the age stages and low at the two ends, and which was higher in the female than in the male. With the increase of SDI, the prevalence of AMD was increased linearly.@*CONCLUSIONS@#The disease burden of AMD in China is increased significantly and is positively correlated with the social development from 1990 to 2019. It is of great significance to study the relationship between epidemilolgical data of AMD and social development level for diagnosis treatment and policy of AMD.

Objective To analyze the changing trend of disease burden attributable to renal insufficiency in cardiovascular disease (CVD) among the elderly in China from 1990 to 2019, and to forecast the disability-adjusted life years (DALY) in the next 10 years, so as to provide a reference basis for accurate prevention and control of CVD attributable to renal insufficiency in China. Methods Data were obtained from the Global Health Data Exchange (GHDx) database to describe the current status of CVD prevalence attributable to renal insufficiency. The joinpoint model was used to estimate the annual percentage change and average annual percentage change to assess the temporal trend of CVD attributable to renal insufficiency in China. An autoregressive moving average model was created by R4.0.2 software to predict the disease burden of CVD attributable to renal insufficiency in China. Results Compared with 1990, CVD mortality and DALY rates attributed to renal insufficiency increased in the male elderly population and decreased in women. Mortality and DALY rates attributed to ischemic heart disease, ischemic stroke, and peripheral arterial disease attributed to renal insufficiency showed an increasing trend, and mortality and DALY rates for cerebral hemorrhage decreased. There was an overall increasing trend in the attribution of CVD due to renal insufficiency. Conclusion The burden of diseases attributable to renal insufficiency in Chinese elderly with CVD is relatively high, and the impact on each disease is different, which requires the attention of relevant authorities.

Objective To investigate the trends in the disease burden of schistosomiasis worldwide and in China, and Zimbabwe from 1990 to 2019, so as to provide insights into the formulation of the schistosomiasis control strategy in Zimbabwe. Methods Based on Global Burden of Disease Study 2019 (GBD 2019) data sources, the age-standardized prevalence, mortality, disability-adjusted life year (DALY) rate of schistosomiasis were compared in the world, China, and Zimbabwe and the trends in the disease burden of schistosomiasis from 1990 to 2019 were investigated using Joinpoint regression analysis. In addition, the associations between the burden of schistosomiasis worldwide and in China and Zimbabwe from 1990 to 2019 and socio-demographic index (SDI) were examined using Pearson correlation analysis. Results The age-standardized prevalence, mortality, and DALY rate of schistosomiasis were 1 804.95/105, 0.14/105 and 20.92/105 in the world, 707.09/105, 0.02/105 and 5.06/105 in China, and 2 218.90/105, 2.39/105 and 90.09/105 in Zimbabwe in 2019, respectively. The global prevalence, mortality, and DALY rate of schistosomiasis appeared a tendency towards a rise followed by a decline with age in 2019, while the prevalence and DALY rate of schistosomiasis appeared a tendency towards a sharp rise followed by a fluctuating decline in both China and Zimbabwe, and the mortality of schistosomiasis appeared a tendency towards a rise. The age-standardized prevalence [average annual percent change (AAPC) = −1.31%, −2.22% and −6.12%; t = −20.07, −83.38 and −53.06; all P values < 0.05)] and DALY rate of schistosomiasis (AAPC = −1.91%,−4.17% and −2.08%; t = −31.89, −138.70 and −16.45; all P values < 0.05) appeared a tendency towards a decline in the world, China and Zimbabwe from 1990 to 2019, and the age-standardized mortality of schistosomiasis appeared a tendency towards a decline in the world and China (AAPC = −3.46% and −8.10%, t = −41.03 and −61.74; both P values < 0.05), and towards a rise followed by a decline in Zimbabwe (AAPC = 1.35%, t = 4.88, P < 0.05). In addition, Pearson correlation analysis showed that the age-standardized prevalence (r = −0.75, P < 0.05), mortality (r = −0.73, P < 0.05), and DALY rate of schistosomiasis (r = −0.77, P < 0.05) correlated negatively with SDI in the world, China and Zimbabwe from 1990 to 2019. Conclusions The disease burden of schistosomiasis appeared a remarkable decline in China from 1990 to 2019, and the prevalence of schistosomiasis showed a tendency towards a decline in Zimbabwe from 1990 to 2019; however, the mortality and DALY rate of schistosomiasis in Zimbabwe topped in the world. A schistosomiasis control strategy with adaptations to local epidemiology and control needs of schistosomiasis is needed to facilitate the elimination of schistosomiasis in Zimbabwe.
