Global estimates of prevalence, deaths, and disability-adjusted life years (DALYs) from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 were examined for metabolic diseases (type ...2 diabetes mellitus T2DM, hypertension, and non-alcoholic fatty liver disease NAFLD). For metabolic risk factors (hyperlipidemia and obesity), estimates were limited to mortality and DALYs. From 2000 to 2019, prevalence rates increased for all metabolic diseases, with the greatest increase in high socio-demographic index (SDI) countries. Mortality rates decreased over time in hyperlipidemia, hypertension, and NAFLD, but not in T2DM and obesity. The highest mortality was found in the World Health Organization Eastern Mediterranean region, and low to low-middle SDI countries. The global prevalence of metabolic diseases has risen over the past two decades regardless of SDI. Urgent attention is needed to address the unchanging mortality rates attributed to metabolic disease and the entrenched sex-regional-socioeconomic disparities in mortality.

Global estimates from the GBD Study 2019 reveal decreasing mortality rates between 2000 and 2019 for hyperlipidemia, hypertension, and NAFLD, but not for T2DM and obesity. The highest mortality rate due to metabolic disease was found in the Eastern Mediterranean, and in low- to low-middle-income countries. Urgent attention is needed to address high and unchanging mortality rates as well as entrenched sex-regional-socioeconomic disparities in death related to metabolic disease.
Background
There were limited studies on the quantification of the modifiable and nonmodifiable lung cancer burden over time in China. Furthermore, the potential effect of risk factor reduction for ...lung cancer on gains in life expectancy (LE) remains unknown.
Methods
This study explored temporal trends in lung cancer deaths and disability‐adjusted life years (DALY) attributable to modifiable risk factors from 1990 to 2019, based on the 2019 Global Burden of Disease Study. The abridged period life table method was used to quantify the effect of risk factors on LE. The authors used the decomposition approach to estimate contributions of aging metrics to change in the lung cancer burden.
Results
Nationally, the majority of lung cancer deaths and DALYs were attributable to behavioral and environmental risk clusters. Potential gains in life expectancy (PGLE) at birth would be 0.78 years for males and 0.35 years for females if the exposure to risk factors was mitigated to the theoretical minimum level. Tobacco use had the most robust impact on LE for both sexes (PGLE: 0.71 years for males and 0.19 years for females). From 1990 to 2019, risk‐attributable age‐standardized death and DALY rates of lung cancer showed an increasing trend in both sexes; adult population growth imposed 245.9 thousand deaths and 6.2 million DALYs for lung cancer.
Conclusions
The modifiable risk‐attributable lung cancer burden remains high in China. Effective tobacco control is the critical step toward addressing the lung cancer burden. Adult population growth was the foremost driver of transition in the age‐related lung cancer burden.
Plain Language Summary
We estimate the lung cancer burden attributable to modifiable and nonmodifiable contributors and the effect of risk factor reduction for lung cancer on the life expectancy in China.
The findings suggest that the majority of lung cancer deaths and disability‐adjusted life years were attributable to behavioral risk clusters, and the risk‐attributable lung cancer burden increased nationally from 1990 to 2019.
The average gains in life expectancy would be 0.78 years for males and 0.35 years for females if the exposure to risk factors for lung cancer was reduced to the theoretical minimum risk exposure level.
Adult population growth was identified as the foremost driver of variation in the aging lung cancer burden.
This study emphasizes the crucial role of context‐specific interventions and policies targeted to reducing modifiable risk exposure and tackling population aging to effectively mitigate the lung cancer burden and ultimately improve the life expectancy.
In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is ...essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries.
GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution.
Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990–2010 time period, with the greatest annualised rate of decline occurring in the 0–9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10–24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10–24 years were also in the top ten in the 25–49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50–74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI.
As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and development investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

The management of chronic wounds has presented a significant dilemma, which is evident not only in clinical treatment but also in the substantial burden it places on medical resources. The global ...COVID‐19 pandemic in 2020 is likely to further exacerbate this trend. Therefore, it is imperative to delve deeper into the impact of chronic wound on disease burden across different regions and populations. In this study, we focused on decubitus ulcers (DU) as representative chronic wounds and utilized data from the Global Burden of Disease (GBD) 2019 database (http://ghdx.healthdata.org/gbd-results-tool) pertaining to age, gender, region, year and socio‐demographic index (SDI) group. Disability‐adjusted life years (DALYs) and mortality were utilized as indicators to assess the burden of DU. The analysis and visualization were performed using R software (version 4.2.3). A decrease in the global ASRs of DALYs and mortality for DU was observed across most regions between 1990 and 2019. The reduction in burden was particularly significant in regions characterized by a high SDI, while regions with a high‐middle SDI experienced an increase. The burden of DU increased with age for both males and females, with males generally experiencing a higher burden compared to females. Strengthening population‐based data on the prevalence of DU and implementing dynamic monitoring at the public health level will enable policymakers to develop evidence‐based strategies for efficient allocation of healthcare resources.
Low bone mineral density (LBMD), including osteoporosis and low bone mass, has becoming a serious public health concern. We aimed to estimate the disease burden of LBMD and its related fractures in ...204 countries and territories over the past 30 years.
We collected detailed information and performed a secondary analysis for LBMD and its related fractures from the Global Burden of Disease Study 2019. Numbers and age-standardized rates related to LBMD of disability-adjusted life-years (DALYs) and deaths in 204 countries and territories were compared by age, gender, socio-demographic index (SDI), and location.
Global deaths and DALYs number attributable to LBMD increased from 207 367 and 8 588 936 in 1990 to 437 884 and 16 647 466 in 2019, with a raise of 111.16% and 93.82%, respectively. DALYs and deaths number of LBMD-related fractures increased 121.07% and 148.65% from 4 436 789 and 121248 in 1990 to 9 808 464 and 301 482 in 2019. In 2019, the five countries with the highest disease burden of DALYs number in LBMD-related fractures were India (2 510 288), China (1 839 375), United States of America (819 445), Japan (323 094), and Germany (297 944), accounting for 25.59%, 18.75%, 8.35%, 3.29%, and 3.04%. There was a quadratic correlation between socio-demographic index (SDI) and burden of LBMD-related fractures: DALYs rate was 179.985-420.435SDI+417.936SDI
(R
0.188, p<0.001); Deaths rate was 7.879-13.416SDI+8.839 SDI
(R
0.101, p<0.001).
The global burden of DALYs and deaths associated with LBMD and its related fractures has increased significantly since 1990. There were differences in disease burden between regions and countries. These estimations could be useful in priority setting, policy-making, and resource allocation in osteoporosis prevention and treatment.
China's profoundly rapid modernization in the past two decades has resulted in dramatic changes in indoor environmental exposures. Among these changes, exposure to phthalates has attracted increasing ...attention. We aimed to characterize indoor phthalate exposure and to estimate the disease burden attributable to indoor phthalate pollution from 2000 to 2017 in China. We integrated the national exposure level of indoor phthalates from literature through systematic review and Monte Carlo simulation. Dose‐response relationships between phthalate exposure and health outcomes were obtained by systematic review and meta‐analysis. Based on existing models for assessing probabilities of causation and a comprehensive review of available data, we calculated the disability‐adjusted life years (DALYs) among the general Chinese population resulting from exposure to indoor phthalate pollution. We found that DnBP, DiBP, and DEHP were the most abundant phthalates in indoor environments of residences, offices, and schools with medians of national dust phase concentration from 74.5 µg/g to 96.3 µg/g, 39.6 µg/g to 162.5 µg/g, 634.2 µg/g to 1,394.7 µg/g, respectively. The national equivalent exposure for children to phthalates in settled dust was higher than that of adults except for DiBP and DnOP. Dose‐response relationships associated with DEP, DiBP, DnBP, BBzP, and DEHP exposures were established. Between 2000 and 2017, indoor phthalate exposure in China has led to 3.32 million DALYs per year, accounting for 0.90% of total DALYs across China. The annual DALY associated with indoor phthalate pollution in China was over 2000 people per million, which is about 2~3 times of the DALY loss due to secondhand smoke (SHS) in six European countries or the sum of the DALY loss caused by indoor radon and formaldehyde in American homes. Our study indicates a considerable socioeconomic impact of indoor phthalate exposure for a modernizing human society. This suggest the need for relevant national standard and actions to reduce indoor phthalate exposure.
Comprehensive evidence about the burden of infectious diseases in the Western Pacific Region is scarce. We thus examined the disease burden of infectious diseases in Japan in terms of ...disability-adjusted life years (DALYs).
We extracted national claims data from Japan's universal health insurance system to estimate the burden of disease for selected infections between 2015 and 2020 using DALYs. The mortality rate, disability duration and severity weight of each disease were estimated based on national data and literature reviews.
Disease burden per 100,000 population was 1307.0 in 2015 and 972.1 in 2020 for bloodstream infections (BSI), 796.5 DALYs in 2015 and 498.9 DALYs in 2020 for pneumonia, 171.5 in 2015 and 149.4 in 2020 for meningitis and 11.6 in 2015 and 11.4 in 2020 for urinary tract infections (UTI). Only surgical site infections (SSI) showed a slightly increasing trend over the 5-year period, from 2.2 in 2015 to 2.8 in 2020.
Our results showed that the disease burden of the five major infectious diseases was higher in Japan than in other countries. However, while the burden of SSI increased, the burden of pneumonia, meningitis, BSI and UTI gradually decreased year on year. The possible causes of the decreased morbidity should be examined in future work.
To provide an updated analysis of the burden of ischemic stroke in the United States.
Using the Global Burden of Disease database, we estimated age-standardized, population-adjusted rates of ...incidence, prevalence, mortality, and disability-adjusted life years from 2010 to 2019, with regional comparisons. Deaths and disability-adjusted life years were compared in 2010–2014 and 2015–2019 to assess the potential effect of increased mechanical thrombectomy use. The attributable, disability-adjusted life years for twenty risk factors were estimated, ranked, and trended.
Incident ischemic strokes decreased by 11.4 % across the study period from 65.7 (55.9–77.3) to 58.2 (49.0–69.5) per 100,000. Prevalence (-8.2 %), mortality (-1.9 %), and disability-adjusted life years (-4.4 %) all declined. All regions showed reductions in all burden measures, with the South consistently having the highest burden yet the largest reduction in incidence (-12.6 %) and prevalence (-10.5 %). Deaths (p < 0.0001) and DALYs (p < 0.0001) significantly differed between the pre- and post-mechanical thrombectomy eras. Total attributable disability-adjusted life years for all risk factors decreased from 304.7 (258.5–353.2) in 2010 to 288.9 (242.2–337.2) in 2019. In 2019, the risk factors with the most disability-adjusted life years were hypertension, hyperglycemia, and obesity with no state-based differences. Across the study period, disability-adjusted life years attributable to leading risk factors decreased among men but decreased less or increased among women.
The burden of ischemic stroke decreased during the study period. Declines in deaths and disability-adjusted life years suggest a mitigating impact of mechanical thrombectomy. While disability-adjusted life years attributable to leading risk factors decreased, sex-based disparities were observed.
Data on the global epidemiology of varicella‐zoster virus infection (VZVI) is limited. This study aimed to investigate the burden of VZVI based on the global burden of disease study 2019 data. The ...age‐standardized rates, including the incidence, death, disability‐adjusted life years (DALYs), and the estimated annual percentage changes (EAPC) of VZVI were calculated to evaluate the disease burden of VZVI. The global numbers of incident and death cases due to VZVI were 83 963 744 and 14 553, respectively. The age‐standardized incidence rate of VZVI increased slightly all over the world, while the age‐standardized death and DALYs rate decreased from 1990 to 2019 (EAPC = −2.31 and −1.61, respectively). The younger age (<5 years old) and older groups had the highest VZVI burden. The high sociodemographic index (SDI) region had the highest age‐standardized incidence rates in 2019 (1236.28/100 000, 95% uncertainty interval UI: 1156.66–1335.50) and the low SDI region had the lowest incidence (1111.24/100 000, 95% UI: 1040.46–1209.55). The age‐standardized death and DALYs rate of VZVI decreased with the increase of SDI. Amongst the 21 geographical regions, the high‐income Asia‐Pacific (1269.08/100 000) region had the highest age‐standardized incidence rate in 2019, while Sub‐Saharan Africa had the highest age‐standardized death and DALYs rate. The global incidence of VZVI has continued to increase in the past 3 decades, while the age‐standardized death and DALYs rates have decreased. More attention should be paid to the younger and older population, as well as low SDI regions.
Highlights
The age‐standardized incidence of VZVI has slightly increased, while the age‐standardized death and DALYs rate has significantly decreased.
The highest disease burden of VZVI is concentrated in the extremes of age, concentrated in either elderly or children under five.
The death and DALYs of VZVI, across different age groups, are negatively associated with the sociodemographic index levels.
