Global, regional, and national burdens of nutritional deficiencies, from 1990 to 2019.

The epidemiological and burden characteristics of nutritional deficiencies (NDs) have been evolving, and it is crucial to identify geographical disparities and emerging trends. This study aimed to analyze the global, regional, and national trends in the burden of NDs over the past 30 years. Data were obtained from the Global Burden of Disease (GBD) 2019 database for the period 1990-2019. The study examined the incidence rates and disability-adjusted life years (DALYs) of NDs at various levels. Globally, the incidence rate of NDs decreased from 2226.2 per 100,000 in 2019 to 2096.3 per 100,000 in the same year, indicating a decline of 5.8%. The average annual percentage change (AAPC) was -0.21 (-0.31 to -0.11). Similarly, DALYs, prevalence, and mortality rates of NDs exhibited significant declines (AAPC = -3.21 [-3.45 to -2.96], AAPC = -0.53 [-0.55 to -0.51], and AAPC = -4.97 [-5.75 to -4.19], respectively). The incidence rate of NDs varied based on age group, gender, cause, and geographical area. Moreover, a negative association was observed between incidence and the sociodemographic index. At the regional level, the South Asia and Sub-Saharan Africa regions had the highest incidence rates of NDs. In conclusion, the global incidence rate of NDs showed a mixed pattern, while the DALY rate consistently declined. Additionally, prevalence and mortality rates of NDs decreased between 1990 and 2019.

Comparison of the burden of digestive diseases between China and the United States from 1990 to 2019.

Introduction: China has experienced unprecedented transformations unseen in a century and is gradually progressing toward an emerging superpower. The epidemiological trends of digestive diseases in the United States (the US) have significant prescient effects on China. Methods: We extracted data on 18 digestive diseases from the Global Burden of Diseases 2019 Data Resource. Linear regression analysis conducted by the JoinPoint software assessed the average annual percentage change of the burden. We performed subgroup analyses based on sex and age group. Results: In 2019, there were 836.01 and 180.91 million new cases of digestive diseases in China and the US, causing 1558.01 and 339.54 thousand deaths. The age-standardized incidence rates of digestive diseases in China and the US were 58417.87/100,000 and 55018.65/100,000 respectively, resulting in age-standardized mortality rates of 81.52/100,000 and 60.88/100,000. The rates in China annually decreased by 2.149% for mortality and 2.611% for disability-adjusted life of year (DALY). The mortality and DALY rates of the US, respectively, had average annual percentage changes of -0.219 and -0.251. Enteric infections and cirrhosis and other chronic liver diseases accounted for the highest incidence and prevalence in both counties, respectively. The burden of multiple digestive diseases exhibited notable sex disparities. The middle-old persons had higher age-standardized prevalence rates. Conclusion: China bore a greater burden of digestive diseases, and the evolving patterns were more noticeable. Targeted interventions and urgent measures should be taken in both countries to address the specific burden of digestive diseases based on their different epidemic degree.

Global association of incidence between atrial fibrillation and the major gastrointestinal cancers: An analysis based on the 2019 Global burden of disease study.

Atrial Fibrillation (AF) and gastrointestinal (GI) cancers are age-related diseases with shared environmental risk factors and underlying biological mechanisms. This study aimed to assess the association between AF and GI cancers on a global scale, analyzing incidence data from 204 countries. This ecological study utilized data from the Global Burden of Disease. Spearman's correlation and logistic regression analyses were employed to assess the association between AF and specific GI cancers, including esophagus cancer (EC), colon and rectum cancer (CRC), liver cancer (LC), pancreatic cancer (PC), and stomach cancer (SC). AF, CRC and PC exhibited increasing crude incidence rates from 2000 to 2019, whereas EC and SC demonstrated decreasing trends specifically in females. From 2000 to 2010, there was a noticeable fall in the incidence rate of LC, which was followed by a minor growth through 2019. The age-standardized incidence rate (ASIR) of AF was positively correlated with CRC and PC, but a negative relationship with AF was revealed for EC. Unexpectedly, no significant relationship was discovered for SC and LC associated with AF. Logistic regression analysis revealed a positive correlation between a country's ASIR of AF and its ASIR of CRC, LC and PC. Conversely, these countries demonstrated a decreased ASIR for EC. Our findings showed a significant correlation between national incidence rates of AF with CRC and PC, worldwide. Countries with higher ASIR of AF had higher ASIR of CRC and PC. Additional research is necessary to confirm the association between GI cancers and AF at the individual level.

Overview of the Global and US Burden of Preterm Birth.

Preterm birth (PTB) is the leading cause of morbidity and mortality in children globally, yet its prevalence has been difficult to accurately estimate due to unreliable methods of gestational age dating, heterogeneity in counting, and insufficient data. The estimated global PTB rate in 2020 was 9.9% (95% confidence interval: 9.1, 11.2), which reflects no significant change from 2010, and 81% of prematurity-related deaths occurred in Africa and Asia. PTB prevalence in the United States in 2021 was 10.5%, yet with concerning racial disparities. Few effective solutions for prematurity prevention have been identified, highlighting the importance of further research.

Global Burden of Alzheimer's Disease and Other Dementias Attributed to High Fasting Plasma Glucose from 1990 to 2019.

BACKGROUND: Burden of Alzheimer's disease (AD) and other dementias have grown rapidly over the decades, and high fasting plasma glucose (HFPG) was one of the well-established risk factors. It is urgently needed to estimate the global burden of AD and other dementias attributable to high fasting plasma glucose between regions, countries, age groups, and sexes to inform development of effective primary disease prevention strategies and intervention policies. METHODS: The burden of AD and other dementias attributable to HFPG was estimated based on a modeling strategy using the Global Burden of Disease Study 2019 dataset. The disease burden and time trend globally and by region, country, development level, age group, and sex were evaluated. RESULTS: The number of AD and other dementias-related deaths attributable to HFPG increased from 42,998.23 (95% uncertainty interval, UI: 4459.86-163,455.78, the year of 1990) to 159,244.53 deaths (95% UI 18,385.23-583,514.15, the year of 2019). The age-standardized death rate increased from 1.69 (95% UI 0.18-6.54) in 1990 to 2.24 (95% UI 0.26-8.24) in 2019. The burden was higher in more developed regions. The burden in women was double that in men, that HFPG-attributable AD and other dementias caused 99,812.79 deaths (95% UI 9005.67-387,160.60) in women and 59,431.74 deaths (95% UI 5439.02-214,819.23) in men, with age-standardized death rate of 2.27 (95% UI 0.20-8.79) per 100,000 population in women and 2.20 (95% UI 0.20-8.00) in men. CONCLUSION: Findings from the current study emphasizes the urgent requirement for targeted interventions in high-development regions, as well as the importance of proactive measures in middle-development countries in protection of AD and other dementias. The gender disparity necessitates the integration of gender-specific considerations in targeted approaches in prevention of AD and other dementias.

Temporal trends in the prevalence and death of ischemic heart disease in women of childbearing age from 1990 to 2019: a multilevel analysis based on the Global Burden of Disease Study 2019.

Background: Our objective is to describe the current prevalence and death of ischemic heart disease (IHD) in women of childbearing age (WCBA) at the global, regional, and national levels and to analyze its temporal trends from 1990 to 2019. Methods: WCBA was defined as women aged 15-49 years. Estimates and 95% Uncertainty Intervals (UI) of IHD prevalence and death numbers for seven age groups were extracted from the 2019 Global Burden of Disease Study. The age-standardized prevalence and death rate (ASPR and ASDR) of IHD in WCBA was estimated using the direct age-standardization method. Joinpoint regression analysis was used to calculate average annual percent change (AAPC) to represent the temporal trends from 1990 to 2019. Results: Between 1990 and 2019, the global ASPR of IHD experienced a 3.21% increase, culminating in 367.21 (95% UI, 295.74-430.16) cases per 100,000 individuals. Conversely, the ASDR decreased to 11.11 (95% UI, 10.10-12.30) per 100,000 individuals. In 2019, among the five sociodemographic index (SDI) regions, the highest ASPR was observed in the high-middle SDI region, whereas the highest ASDR was found in the low-middle SDI region. Regionally, the Caribbean reported the highest ASPR (563.11 per 100,000 individuals; 95% UI, 493.13-643.03), and Oceania reported the highest ASDR (20.20 per 100,000 individuals; 95% UI, 13.01-31.03). At the national level, Trinidad and Tobago exhibited the highest ASPR (730.15 per 100,000 individuals; 95% UI, 633.96-840.13), and the Solomon Islands had the highest ASDR (77.77 per 100,000 individuals; 95% UI, 47.80-121.19). Importantly, over the past three decades, the global ASPR has seen a significant increase [AAPC = 0.11%, 95% Confidence Interval (CI): 0.09-0.13; P < 0.001], while the ASDR has demonstrated a significant decreasing trend (AAPC = -0.86%, 95% CI: -1.11 to -0.61; P < 0.001). Air pollution, tobacco use, high systolic blood pressure, elevated body mass index, dietary risks, and high LDL cholesterol have been identified as the leading six risk factors for IHD-related deaths among WCBA in 2019. Conclusions: Despite the significant decline in the global ASDR for IHD among WCBA over the last thirty years, the ASPR continues to escalate. We need to remain vigilant about the increased burden of IHD in WCBA. It calls for aggressive prevention strategies, rigorous control of risk factors, and the enhancement of healthcare coverage to mitigate the disease burden of IHD among WCBA in forthcoming years.

The burden of disease and economic growth: The nonlinear effect of population age structure.

This study aims to detangle the impact of health on economic growth as empirical evidence shows a mixture of findings. We use data on the Burden of Disease (BoD) from the Institute of Health Metric Evaluation (IHME) to measure health capital and the economic data of 87 countries from 1990 to 2018. Using panel threshold regression, this study shows that the old dependency ratio is a good measure of the threshold variable, which divides the country groups into four. The BoD, whether it comes from communicable diseases (CD), non-communicable diseases (NCD), or injuries, has a negative impact on economic growth. However, the negative relation is somewhat diminished as the population gets older, demonstrating that the BoD's impact on economic growth is less pronounced for the older population than the younger population.

Global, regional, and national burden of atrial fibrillation/flutter related to metabolic risks over three decades: estimates from the global burden of disease study 2019.

AIMS: Atrial fibrillation/atrial flutter (AF/AFL) remains a significant public health concern on a global scale, with metabolic risks playing an increasingly prominent role. This study aimed to investigate comprehensive epidemiological data and trends concerning the metabolic risks related-AF/AFL burden based on the data from the Global Burden of Disease (GBD) study 2019. METHODS & RESULTS: The analysis of disease burden focused on numbers, age-standardized rates (ASR) of deaths, disability-adjusted life years (DALYs), and estimated annual percentage change (EAPC), while considering factors of age, sex, sociodemographic index (SDI), and locations. In 2019, there was a culmination of 137 179 deaths and 4 099 146 DALYs caused by metabolic risks related-AF/AFL worldwide, with an increase of 162.95% and 120.30% respectively from 1990. High and high-middle SDI regions predominantly carried the burden of AF/AFL associated with metabolic risks, while a shift towards lower SDI regions had been occurring. Montenegro had the highest recorded death rate (7.6 per 100 000) and DALYs rate (146.3 per 100 000). An asymmetrically inverted V-shaped correlation was found between SDI and deaths/DALYs rates. Moreover, females and the elderly exhibited higher AF/AFL burdens, and young adults (over 40 years old) also experienced an annual increase. CONCLUSIONS: The global AF/AFL burden related to metabolic risks has significantly increased over past three decades, with considerable spatiotemporal, gender-based, and age-related heterogeneity. These findings shed valuable light on the trends in the burden of metabolic risks related-AF/AFL, and offered insights into corresponding strategies.

Comparison of a 30-year trend of incidence, prevalence, and DALY due to low back pain in Iran with Low- and High-SDI countries; Based on GBD study 2019 Data.

Introduction: Low back pain (LBP) represents the leading cause of disability worldwide and is a major economic and welfare problem. This study aimed to report incidence, prevalence, and disability-adjusted life years (DALY) rates of LBP in Iran by gender and different sociodemographic index (SDI) countries from 1990 to 2019. Methods: The age-standardized LBP and incidence, prevalence, and DALY were extracted based on the Global Burden of Disease (GBD) 2019 in Iran for males and females, and low- and high-SDI countries during 1990- 2019. Results: GBD 2019 data for LBP in Iran indicate a significant downward trend of incidence and prevalence from 1993 to 2019 in males, females, and both, except during the 1999-2002 period for females. A sharp reduction is seen in LBP incidence and prevalence from 1996 to 1999. Gender is not a determining factor in the LBP prevalence in Iran. Regarding the SDI categories, Iran had the highest incidence rate compared to countries with low- and high SDIs. High-SDI countries had the highest prevalence and DALY compared with Iran and low-SDI countries. Conclusion: The age-standardized incidence and prevalence of LBP in Iran showed a downward trend, from 1993 to 2019, especially from 1996 to 1999. Comparing Iran with low- and high-SDI countries, a heavier incidence of LBP was observed in Iran and heavier prevalence and DALY were seen in high-SDI countries. Therefore, more therapeutic healthcare interventions are required to reduce the LBP burden more effectively.

Global, regional, and national temporal trend in burden of major depressive disorder from 1990 to 2019: An analysis of the global burden of disease study.

Major depressive disorder (MDD) is one of the leading causes of disability worldwide. Comprehensive description of the global burden of MDD and its attributable risk factors is essential for policymaking but currently lacking. In this study, we aim to estimate the burden of MDD in terms of incidence, prevalence, and years lived with disability (YLDs), along with its attributable risk factors at global, regional, and rational level between 1990 and 2019, using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Data analysis was completed on July 1, 2023. In 2019, 274.80 million (95 % uncertainty interval [UI], 241.28 to 312.77) new cases of MDD were identified globally, with an increase of 59 % from 1990. A total of 37.20 million (25.65 to 51.22) YLDs were attributable to MDD, accounting for the largest proportion of mental disorder YLDs (29.7 %). Countries in the low sociodemographic index quantile exhibited the highest age-standardized incidence rate of MDD, with Uganda (7836.2, per 100,000 person-years, 6713.7 to 9181.1) and Palestine (7687.7, 6546.1 to 9023.9) reporting the highest rates among them. The United States had the highest increase in age-standardized rates, with an average annual percent change of 0.99. Females had 1.6 times higher age-standardised rates than males, ranging from 1.2 (Oceania) to 2.2 (tropical Latin America) times across 21 regions. Globally, the proportions of YLDs due to MDD attributable to bullying victimization, childhood sexual abuse, and intimate partner violence were 4.86 %, 5.46 %, and 8.43 % in 2019, respectively. The heavy burden of MDD serves as a stark reminder that a coordinated response from governments and health communities is urgently needed to scale up mental health services and implement effective interventions, particularly in low-income countries.

Temporal trends in the visual impairment burden attributable to high fasting plasma glucose levels: a population-based study.

AIMS: Elevated fasting plasma glucose (FPG) levels have been associated with visual impairment. Recognising global patterns of high FPG level exposure can facilitate the prevention and treatment of related visual impairment. We aimed to assess the trends of the visual impairment burden attributable to high FPG levels globally, regionally, nationally, and by income level. METHODS: We obtained data on the visual impairment burden attributable to high FPG levels from the Global Burden of Disease Study 2019. We evaluated the trends of related disability-adjusted life-years (DALYs) from 1990 to 2019 through joinpoint regression analysis and calculated the annual percentage change (APC) and average APC (AAPC). Countries/territories were categorised into high-, upper-middle-, lower-middle-, and low-income groups based on the 2019 World Bank criteria. RESULTS: The age-standardised rate of DALYs due to visual impairment attributable to high FPG levels significantly increased globally, from 6.75 (95% uncertainty interval [UI], 1.55-15.79) in 1990 to 8.44 per 100,000 population (95% UI, 2.00-19.63) in 2019 (AAPC, 0.79; 95% confidence interval [CI], 0.69-0.89; p < 0.001). The largest increases were observed in high-income (AAPC, 0.73; 95% CI, 0.60-0.85) and lower-middle-income countries/territories (AAPC, 0.68; 95% CI, 0.62-0.73). In 2019, lower-middle-income countries/territories had the highest age-standardised DALY rate (18.94 per 100,000 population; 95% UI, 4.39-43.98), whereas high-income countries/territories had the lowest (2.97 per 100,000 population; 95% UI, 0.75-6.74). CONCLUSIONS: The visual impairment burden associated with elevated FPG levels has increased significantly, necessitating enhanced public health prevention measures, clinical management, and treatment to mitigate adverse outcomes.

Disability and costs of IHD attributable to the consumption of trans-fatty acids in Brazil.

OBJECTIVE: To estimate the disability and costs of the Brazilian Unified Health System for IHD attributable to trans-fatty acid (TFA) consumption in 2019. DESIGN: This ecological study used secondary data from the Global Burden of Disease (GBD) Study 2019 to estimate the years lived with disability from IHD attributable to TFA in Brazil in 2019. Data on direct costs (purchasing power parity: 1 Int$ = R$ 2·280) were obtained from the Hospital and Ambulatory Information Systems of the Brazilian Unified Health System. Moreover, the total costs in each state were divided by the resident population in 2019 and multiplied by 10 000 inhabitants. The relationship between the socio-demographic index, disease and economic burden was investigated. SETTING: Brazil and its twenty-seven states. PARTICIPANTS: Adults aged ≥ 25 years of both sexes. RESULTS: IHD attributable to TFA consumption resulted in 11 165 years lived with disability (95 % uncertainty interval 932­18 462) in 2019 in Brazil. A total of Int$ 54 546 227 (95 % uncertainty interval 4 505 792­85 561 810) was spent in the Brazilian Unified Health System in 2019 due to IHD attributable to TFA, with the highest costs of hospitalisations, for males and individuals aged ≥ 50 years or over. The highest costs were observed in Sergipe (Int$ 6508/10 000; 95 % uncertainty interval 576­10 265), followed by the two states from the South. Overall, as the socio-demographic index increases, expenditures increase. CONCLUSIONS: TFA consumption results in a high disease and economic IHD burden in Brazil, reinforcing the need for more effective health policies, such as industrial TFA elimination, following the international agenda.

The long-term spatio-temporal trends in burden and attributable risk factors of major depressive disorder at global, regional and national levels during 1990-2019: a systematic analysis for GBD 2019.

AIMS: Caused by multiple risk factors, heavy burden of major depressive disorder (MDD) poses serious challenges to public health worldwide over the past 30 years. Yet the burden and attributable risk factors of MDD were not systematically known. We aimed to reveal the long-term spatio-temporal trends in the burden and attributable risk factors of MDD at global, regional and national levels during 1990-2019. METHODS: We obtained MDD and attributable risk factors data from Global Burden of Disease Study 2019. We used joinpoint regression model to assess the temporal trend in MDD burden, and age-period-cohort model to measure the effects of age, period and birth cohort on MDD incidence rate. We utilized population attributable fractions (PAFs) to estimate the specific proportions of MDD burden attributed to given risk factors. RESULTS: During 1990-2019, the global number of MDD incident cases, prevalent cases and disability-adjusted life years (DALYs) increased by 59.10%, 59.57% and 58.57%, respectively. Whereas the global age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR) and age-standardized DALYs rate (ASDR) of MDD decreased during 1990-2019. The ASIR, ASPR and ASDR in women were 1.62, 1.62 and 1.60 times as that in men in 2019, respectively. The highest age-specific incidence, prevalence and DALYs rate occurred at the age of 60-64 in women, and at the age of 75-84 in men, but the maximum increasing trends in these age-specific rates occurred at the age of 5-9. Population living during 2000-2004 had higher risk of MDD. MDD burden varied by socio-demographic index (SDI), regions and nations. In 2019, low-SDI region, Central sub-Saharan Africa and Uganda had the highest ASIR, ASPR and ASDR. The global PAFs of intimate partner violence (IPV), childhood sexual abuse (CSA) and bullying victimization (BV) were 8.43%, 5.46% and 4.86% in 2019, respectively. CONCLUSIONS: Over the past 30 years, the global ASIR, ASPR and ASDR of MDD had decreased trends, while the burden of MDD was still serious, and multiple disparities in MDD burden remarkably existed. Women, elderly and populations living during 2000-2004 and in low-SDI regions, had more severe burden of MDD. Children were more susceptible to MDD. Up to 18.75% of global MDD burden would be eliminated through early preventing against IPV, CSA and BV. Tailored strategies-and-measures in different regions and demographic groups based on findings in this studywould be urgently needed to eliminate the impacts of modifiable risk factors on MDD, and then mitigate the burden of MDD.

The health state of France before COVID-19 pandemic between 1990 and 2019: an analysis of the Global Burden of Disease study 2019.

Background: France faces nowadays some major challenges regarding its health care system including medically underserved areas, social health inequalities, and hospital pressures. Various indicators and sources of data allow us to describe the health status of a population and, consequently, to assess the impact of these challenges. We assessed the burden of diseases before COVID-19 in France in 2019 and its evolution from 1990 to 2019, and compared it with Western European countries. Methods: We used specific Global Burden of Diseases (GBD) metrics: socio-demographic index (SDI), life expectancy (LE), healthy life expectancy (HALE), years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) with their 95% uncertainty interval (95% UI). We compared French age-standardized metrics to those for other Western European Countries for both sexes and also between 1990 and 2019. We also described the specific causes of these different metrics. Findings: We observed for life expectancy at birth in France a trend to an improvement over time from 77.2 (95% UI: 77.2-77.3) years in 1990 to 82.9 (82.7-83.1) in 2019, which represented the seventh highest life expectancy among 23 Western European countries. HALE at birth in France increased from 67.0 (64.0-69.7) to 71.5 (68.1-74.5), which represented the fourth highest HALE among 23 Western European countries. In France, the total number of DALY per 100.000 population tended to decrease from 25,192 (22,374-28,351) in 1990 to 18,782 (16,408-21,920) in 2019. As compared to other European countries, the burden due to cardiovascular diseases was lower. Neoplasms and cardio-vascular diseases were the two leading causes of YLLs. Mental and musculoskeletal disorders were the two leading causes of YLDs. Interpretation: Overall, these results highlight a clear trend of improvement in the health status in France with certain differences between western European countries. The health policy makers need to devise interventional strategies to reduce the burden of diseases and injuries, with specific attention to causes such as cancers, cardiovascular diseases, mental health and musculoskeletal disorders.

The burden of skin diseases in China: global burden of Disease Study 2019.

Skin diseases continue to affect human health and cause a significant disease burden on the healthcare system.We aimed to report the changing trends in the burden of skin disease in China from 1990 to 2019, Which has an important role in developing targeted prevention strategies. We applied Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2019 analytical tools to calculate the age-standardized Prevalence and Incidence in 2019, number of years lived with disability (YLDs) and age-standardized YLDs from 1990 to 2019 of skin and subcutaneous diseases, notifiable infectious skin diseases and skin tumors in China. Among the skin and subcutaneous diseases in China in 2019, dermatitis contributed to the greatest YLD (2.17 million, 95% uncertainty interval[UI]: 1.28-3.36). Age-standardized YLD rates for leprosy decreased from 0.09 (95%UI: 0.06-0.13) in 1990 to 0.04 (95%UI: 0.03-0.06) in 2019; the proportional decrease was 55.56% over 30 years. Age-standardized YLDs for HIV and sexually transmitted infections increased by 26% during the same time period. Age-standardized YLDs for non-melanoma skin cancer increased at a much higher rate than melanoma between 1990 and 2019. Dermatitis and scabies continue to have an important role in the burden of skin and subcutaneous disease burden in China. The burden of non-melanoma cell cancer has increased most significantly over the past three decades.

Changing epidemiology of inflammatory bowel disease in children and adolescents.

BACKGROUND: The incidence of inflammatory bowel disease (IBD) is rising worldwide, but epidemiological data on children and adolescents are lacking. Understanding the global burden of IBD among children and adolescents is essential for global standardization of methodology and treatment options. METHODS: This is a cross-sectional study based on aggregated data. We estimated the prevalence and incidence of IBD in children and adolescents between 1990 and 2019 according to the Global Burden of Disease Study 2019 (GBD 2019). Age-standardized rates (ASRs) and estimated annual percentage changes (EAPCs) were used to compare the burden and trends between different regions and countries. RESULTS: In 2019, there were 25,659 new cases and 88,829 prevalent cases of IBD among children and adolescents globally, representing an increase of 22.8% and 18.5%, respectively, compared to 1990. Over the past 30 years, the incidence and prevalence of IBD among children and adolescents have been highest in high SDI regions, with the most significant increases in East Asia and high-income Asia Pacific. At the age level, incidence and prevalence were significantly higher in the 15-19-year-old age group, while the < 5-year-old group showed the most significant increase in incidence and prevalence. CONCLUSION: The incidence of IBD in children and adolescents is significantly on the rise in some countries and regions, and IBD will remain an important public health issue with extensive healthcare and economic costs in the future. The reported IBD burden in children and adolescents at the global, regional, and national levels will assist in the development of more precise health policies.

Discrepancies in dengue burden estimates: a comparative analysis of reported cases and global burden of disease study, 2010-2019.

BACKGROUND: Dengue is a significant mosquito-borne disease. Several studies have utilized estimates from the Global Burden of Disease (GBD) study to assess the global, regional or national burden of dengue over time. However, our recent investigation suggests that GBD's estimates for dengue cases in Taiwan are unrealistically high. The current study extends the scope to compare reported dengue cases with GBD estimates across 30 high-burden countries and territories, aiming to assess the accuracy and interpretability of the GBD's dengue estimates. METHODS: Data for this study were sourced from the GBD 2019 study and various national and international databases documenting reported dengue cases. The analysis targeted the top 30 countries and territories with the highest 10-year average of reported cases from 2010 to 2019. Discrepancies were quantified by computing absolute differences and ratios between the 10-year average of reported cases and GBD estimates. Coefficients of variation (CV) and estimated annual percentage changes (EAPCs) were calculated to assess variations and trends in the two data sources. RESULTS: Significant discrepancies were noted between reported data and GBD estimates in the number of dengue cases, incidence rates, and EAPCs. GBD estimates were substantially higher than reported cases for many entities, with the most notable differences found in China (570.0-fold), India (303.0-fold), Bangladesh (115.4-fold), Taiwan (85.5-fold) and Indonesia (23.2-fold). Furthermore, the GBD's estimates did not accurately reflect the extensive yearly fluctuations in dengue outbreaks, particularly in non-endemic regions such as Taiwan, China and Argentina, as evidenced by high CVs. CONCLUSIONS: This study reveals substantial discrepancies between GBD estimates and reported dengue cases, underscoring the imperative for comprehensive analysis in areas with pronounced disparities. The failure of GBD estimates to represent the considerable annual fluctuations in dengue outbreaks highlights the critical need for improvement in disease burden estimation methodologies for dengue.

Burden of liver cancer attributable to high fasting plasma glucose: a global analysis based on the global burden of disease study 2019.

OBJECTIVE: Liver cancer is the world's sixth most prevalent cancer and the third most frequent cause of cancer-related mortality. Glucose metabolic disorders, indicated by a high fasting plasma glucose (HFPG) concentration, is a contributor to the etiology of liver cancer. With the rising prevalence of glucose metabolic disorders, an assessment of the global burden of liver cancer attributable to HFPG is warranted to inform global liver cancer prevention and control strategies. METHODS AND ANALYSIS: We evaluated the global death and disability-adjusted life years (DALYs) of liver cancer and its subtypes attributable to HFPG at global, regional, and country level. The temporal trend and disparity across geographic regions, social development level, age groups and sex were assessed. RESULTS: In 2019, HFPG-attributable liver cancer was estimated to have caused 4,729.49 deaths and to be responsible for 99,302.25 DALYs. The age-standardized mortality and DALY rate were 0.06 and 1.20 per 100,000 population, and displayed a significantly increasing temporal trend from 1990 to 2019. The age-standardized mortality rate of patients with liver cancer that was attributable to HFPG was higher in men than women. Sex-based disparity narrowed after the women reached menopause, but increased between 1990 and 2019. CONCLUSION: The burden of liver cancer that are attributable to HFPG has been influenced by longitudinal changes in lifestyle, the etiology of liver disease, age demographics, and hormonal status in women. These findings suggest that comprehensive strategies could be implemented, especially for patients with NASH and hyperglycemia, to prevent liver cancer.

Global burden of mesothelioma attributable to occupational asbestos exposure in 204 countries and territories: 1990-2019.

Malignant mesothelioma, a rare and aggressive cancer primarily caused by occupational asbestos exposure, has a poor prognosis. This study leverages the Global Burden of Disease (GBD) 2019 dataset to analyze the burden of mesothelioma linked to occupational asbestos exposure from 1990 to 2019. The analysis includes the number of mesothelioma deaths and disability-adjusted life years (DALYs) attributable to occupational asbestos exposure, focusing on trends in age-standardized mortality rate (ASMR) and age-standardized disability-adjusted life-year rate (ASDR) by year, age, sex, country, region, and Socio-demographic Index (SDI). In 2019, 91.7% of mesothelioma deaths and 85.2% of DALYs were attributable to occupational asbestos exposure, resulting in 26,820 (95% UI 24,312-28,622) deaths and 569,429 (95% UI 509,956-617,484) DALYs. Despite a decline in ASMR and ASDR from 1990 to 2019, the absolute number of deaths and DALYs almost doubled. The United States reported the highest number of mesothelioma deaths, while China had the highest number of DALYs. Age-specific mortality rates and DALYs decreased in the 25-74 age group but increased in the 75+ age group. In conclusion, occupational asbestos exposure remains the primary cause of mesothelioma worldwide, with an increasing number of deaths and DALYs. The highest incidence rates are observed in high-income areas, and rates are rising in low-income areas. It is crucial to raise awareness about the hazards of asbestos to reduce the global burden of mesothelioma linked to occupational exposure.
