Increase In Age-standardized Incidence Rate Research Articles

A study on the global burden of non-melanoma skin cancer from 1990 to 2019

IntroductionThis study aims to provide an overview and analysis of the global disease burden of non-melanoma skin cancer using data from the GBD 2019 database.Material and methodsThis study utilized the global GBD 2019 disease data. The data was categorized into various subgroups based on region, socio-demographic index (SDI), country, gender, and age. We analyzed Incidence Cases, Incidence Rate, disability-adjusted life years (DALYs), DALY Rate, as well as age-standardized indicators and their annualized percent change (EAPC).ResultsThe global burden of non-melanoma skin cancer exhibited an increasing trend from 1990 to 2019. The EAPC for age-standardized incidence rate (ASIR) was 1.13, and the EAPC for age-standardized DALY rate was 0.20. Geographic variations were observed, with the most substantial increase in ASIR observed in High-income North America (EAPC: 2.20), and a significant increase in age-standardized DALY rate in Central Asia (EAPC: 2.32). Countries with high SDI had the highest ASIR and showed the most significant increasing trend (EAPC: 1.97). Overall, the burden of disease for non-melanoma skin cancer increased in all countries globally from 1990 to 2019. The EAPC for incidence cases, DALYs, and ASIR was greater than 0 in almost all countries worldwide, indicating an overall increasing trend.ConclusionsThe global disease burden of non-melanoma skin cancer exhibited significant increasing changes from 1990 to 2019. Several countries in Asia, Africa, and North America experienced a severe disease burden.

Incidence trends of kidney cancer in China from 1990 to 2019: A joinpoint and age-period-cohort analysis.

Occupational carcinogens, smoking, and obesity are believed to be the main causing agents of kidney cancer. China is undergoing rapid industrialization, and hence the people's lifestyles have witnessed tremendous changes. However, the trend of kidney cancer incidence during the late 20th and early 21st centuries remains unexplored in China. Data from the Global Burden of Diseases (GBD; 2019) was retrieved for the incidence of kidney cancer from 1990 to 2019. The rates of disease average annual percentage changes (AAPC) were assessed using joinpoint regression analysis. Age-period-cohort (APC) model was used to assess age, period, and cohort effects on the incidence of the disease simultaneously. An increase in age-standardized incidence rates (ASIR) of kidney cancer was observed from 1990 to 2019 in total residents (1.33 - 4.24), men (1.56 - 6.15), and women (1.11 - 2.31) per 100,000 population suggesting a more obvious increase in males than in females. A consistent increase in age effects was observed in all age groups, especially in males. On the other hand, the 70 - 74 age group in females showed greater age effects. In addition, the period effects analysis showed that the incidence of kidney cancer increased with time. Moreover, the analysis of cohort effects showed a decrease in the disease in birth cohorts, especially before 1940. The incidence of kidney cancer is increasing rapidly in China. The kidney cancer burden will rise in the next decades due to population aging, environmental pollution, occupation, food safety, and so on. Results of this study suggest that more etiological studies should be performed to identify the driving factors for kidney cancer trends, and appropriate preventive measures should be implemented for the age-, period-, and cohort-related factors in the population.

Registration, incidence patterns, and survival trends of central nervous system tumors among children in Germany 1980-2019: An analysis of 40years based on data from the German Childhood Cancer Registry.

Tumors of the central nervous system (CNS) are the second most common type of pediatric cancer in Germany. We aimed to describe registration practice, incidence, and survival patterns for childhood CNS tumors in Germany for the past 40years. Including all CNS tumor cases in children diagnosed at ages 0-14years registered at the German Childhood Cancer Registry (GCCR) in 1980-2019 (for survival analysis 1980-2016), we calculated age-specific and age-standardized incidence rates (ASIR) over time, average annual percentage changes (AAPC), and 1- and 5-year overall survival. While we observed a pronounced increase in ASIR after the establishment of the GCCR during the 1980s, ASIR for all pediatric CNS tumors combined continued to increase markedly from 28.6 per million in 1990-1999 to 43.3 in 2010-2019 (AAPC=2.7% in 1991-2010, AAPC=0.3% in 2010-2019). The 5-year overall survival from CNS tumors improved from 63% in the 1980s, 70% in the 1990s to 79% in 2010-2016. These improvements have occurred across all age groups. Children diagnosed with ependymomas and choroid plexus tumors experienced the strongest increase (from 54% to 81%). Observed increases in incidence rates for pediatric CNS tumors are likely only partially caused by actual increasing case numbers. The majority is a function of improved registration and, to a minor extent, improvements in diagnostics. Survival from pediatric CNS tumors has, by and large, improved consistently, leading to a growing population of childhood cancer survivors with diverse health biographies and risk of lifelong adverse impact on health and wellbeing.

Global, Regional, and National Burden of CKD in Children and Adolescents from 1990 to 2019.

CKD is one of the most prevalent non-communicable health concerns in children and adolescents worldwide; however, data on its incidence, prevalence, disability-adjusted life years (DALYs), and trends in the population are limited. We aimed to assess the global, regional, and national trends in CKD burden in children and adolescents. In this trend analysis based on the 2019 Global Diseases, Injuries, and Risk Factors Study, CKD incidence, prevalence, and DALYs rates per 100,000 population for children and adolescents were reported at the global, regional, and national levels, as well as the average annual percentage change (AAPC). These global trends were analyzed by age, sex, region, and socio-demographic index (SDI). Globally, the overall incidence of CKD (all stages including KRT) in children and adolescents showed an increasing trend (AAPC 0.44 [95% CI 0.36-0.52]) between 1990 and 2019. Similarly, the overall prevalence of CKD also showed an upward trend (AAPC 0.46 [95% CI 0.42-0.51]). However, the DALYs of CKD showed a continuous decreasing trend (AAPC -1.18[-1.37- -0.99]). The population aged 15-19 years had the largest CKD incidence increase during this period. The largest increase in age-standardized incidence rate (ASIR) was in middle SDI countries (AAPC 0.56 [0.45-0.67]). The relationship between the ASIR and SDI showed an inverse U-shaped correlation while the relationship between the age-standardized DALYs rate (ASDR) and SDI showed an inverse trend with SDI. Among adolescents (15-19 years), the ASIR continued to increase for five causes of CKD, owing to type 2 diabetes mellitus and hypertension. Most of the disease burden was concentrated in countries with a lower SDI. Andean Latin America and Central Latin America showed the largest increases in CKD ASIR between 1990 and 2019. The burden of CKD in children and adolescents has increased worldwide, especially in regions and countries with a lower SDI.

Estimates of the global burden of non-Hodgkin lymphoma attributable to HIV: a population attributable modeling study

Human immunodeficiency virus (HIV) significantly increases the risk of non-Hodgkin lymphoma (NHL) development, yet the population-level impact on NHL burden is unquantified. We aim to quantify this association and estimate the global burden of HIV-associated NHL. In this meta-analysis, we searched five databases (PubMed, EMBASE, Cochrane Library, Web of Science, Scopus) from database inception up to September 13, 2023, identifying cohort, case-control, or cross-sectional studies with an effective control group to assess NHL risk among individuals with HIV infection, with two authors extracting summary data from reports. Global and regional HIV-associated population attributable fraction (PAF) and NHL disease burden were calculated based on the pooled risk ratio (RR). HIV prevalence and NHL incidence were obtained from the Joint United Nations Programme on HIV/AIDS (UNAIDS) and Global Burden of Diseases, Injuries, and Risk Factors Study 2019. Trends in NHL incidence due to HIV were assessed using age-standardised incidence rate (ASIR) and estimated annual percentage change (EAPC). This study was registered with PROSPERO (CRD42023404150). Out of 14,929 literature sources, 39 articles met our inclusion criteria. The risk of NHL was significantly increased in the population living with HIV (pooled RR 23.51, 95% CI 17.62-31.37; I2=100%, p<0.0001), without publication bias. Globally, 6.92% (95% CI 2.18%-11.57%) of NHL new cases in 2019 were attributable to HIV infection (30,503, 95% CI 9585-52,209), which marked a more than three-fold increase from 1990 (8340, 95% CI 3346-13,799). The UNAIDS region of Eastern and Southern Africa was the highest affected region, with 44.46% (95% CI 19.62%-58.57%) of NHL new cases attributed to HIV infection. The Eastern Europe and Central Asia region experienced the highest increase in ASIR of NHL due to HIV in the past thirty years, wherein the EAPC was 8.74% (95% CI 7.66%-9.84%), from 2010 to2019. People with HIV infection face a significantly increased risk of NHL. Targeted prevention and control policies are especially crucial for countries in Eastern and Southern Africa, Eastern Europe and Central Asia, to achieve the UNAIDS's '90-90-90' Fast-Track targets. Limited studies across diverse regions and heterogeneity between research have hindered precise estimations for specific periods and regions.

Global epidemiological characteristics of uterine fibroids.

The aim of the study was to examine the burden of uterine fibroids at global, regional and national levels in terms of age and the Socio-demographic Index (SDI). Data were extracted from the GBD 2019 dataset. Estimated annual percentage changes (EAPCs) were calculated to assess the incidence of uterine fibroids, and trends in disability-adjusted life years (DALYs) were examined. All measures examined were stratified by region, country, age and SDI to assess the effects of these variables on the incidence of uterine fibroids. The global age-standardized incidence rate of uterine fibroids increased from 1990 to 2019, with an EAPC of 0.25 (95% confidence interval (CI): 0.24 to 0.27). In contrast, the global age-standardized DALY rate decreased from 1990 to 2019, with an EAPC of -0.27 (95% CI: -0.31 to -0.23). High and low-middle SDI regions experienced significantly higher age-standardized incidence rates. Moreover, in 2019, low and low-middle SDI regions had significantly higher age-standardized DALY rates due to uterine fibroids than other SDI regions. Regionally, Eastern Europe had the highest age-standardized incidence rate of uterine fibroids in 2019, and Tropical Latin America experienced the greatest increase in age-standardized incidence rates from 1990 to 2019. Nationally, Brazil (EAPC = 1.46; 95% CI: 1.35-1.57) and India (EAPC = 1.09; 95% CI: 0.94-1.25) experienced the most significant increases in age-standardized uterine fibroid incidence. Age-standardized DALY rates increased the most in Tropical Latin America, high-income North America and Oceania. Globally, the age-standardized incidence of uterine fibroids has been increasing in recent years. In contrast, age-standardized DALY rates have exhibited a decreasing trend. Eastern Europe, Tropical Latin America, Brazil and India experience the greatest uterine fibroid burden. Globally, women aged 35-39 years and older have an increased risk of uterine fibroids, as reflected in the higher incidence rates among these age groups.

Global trends and regional differences in disease burden of stroke among children: a trend analysis based on the global burden of disease study 2019

BackgroundStroke is a major cause of acute neurological symptoms in children with significant long-term neurological sequelae. However, data of diseases burden on stroke among children was lack. We aimed to be dedicated to analyze and compare global trends as well as regional and sociodemographic differences in stroke prevalence, incidence, mortality and disability-adjusted life-years (DALYs) among children aged 0 ~ 14 years.MethodWe obtained data on annual number of incident strokes, prevalent strokes, deaths, and DALYs, age-standardized incidence rates (ASIRs), prevalence rates (ASPRs), mortality rates (ASMRs) and DALY rates (ASDRs) of stroke among individuals aged 14 years and younger during 1990–2019 from the 2019 Global Burden of Disease Study. To quantify the temporal trends, we calculated changes (%) in number, and used joinpoint regression analysis to identify the average annual percentage changes (AAPCs) of age standardized rates.ResultGlobally, the incident strokes and prevalent strokes increased by 18.51% and 31.97%, respectively, but DALYs due to stroke and deaths due to stroke decreased by 60.18% and 65.03%, respectively, from 1990 to 2019. During the same period, ASIR increased by 0.21% (95%CI: 0.17, 0.24) from 18.02 to 100,000 population in 1990 to 19.11 per 100,000 in 2019; ASPR increased by 0.66% (95%CI: 0.36, 0.96) from 68.88 to 100,000 population in 1990 to 81.35 per 100,000 in 2019; while ASMR (AAPC= -3.94; 95%CI: -4.07, -3.81) and ASDR (AAPC= -3.50; 95%CI: -3.64, -3.36) both decreased. In 2019, the highest age standardized incidence, prevalence, mortality, and DALY rates all occurred in low sociodemographic index (SDI) regions. The greatest increase of age standardized incidence rate (AAPC = 0.21; 95%CI: 0.18, 0.25) and prevalence rate (AAPC = 1.15; 95%CI: 0.34, 1.96) both were in high SDI regions. Eastern Sub-Saharan Africa had the highest ASIR and ASPR in 2019, and Oceania had the highest ASMR and ASDR in 2019 across 21 GBD regions. High-income North America had the largest increase in ASIR (AAPC = 0.63; 95%CI: 0.59, 0.66) and ASPR (AAPC = 1.58; 95%CI: 0.54, 2.63). Against the overall decreasing trend of ASMR, an increasing trend of ASMR was found in Zimbabwe (AAPC = 0.91; 95%CI: 0.44, 1.37) and Botswana (AAPC = 0.74; 95%CI: 0.02, 1.47).ConclusionThe overall increasing stroke incidence and prevalence indicated that prevention and management of stroke among younger population should be critical in the future. Despite stroke mortality with falling trend worldwide, specific countries or territories present worrying increase in stroke mortality. Without urgent implementation of effective primary prevention strategies, the stroke burden of children will probably continue to grow across the world, particularly in high-SDI countries.

Disease Burden and Epidemiological Trends of Chronic Kidney Disease at the Global, Regional, National Levels from 1990 to 2019

Background: Chronic kidney disease (CKD) is a serious public health issue worldwide, but the disease burden of CKD caused by different etiologies and changing trends has not been fully examined. Methods: We collected data from Global Burden of Disease Study 2019 (GBD 2019), including incident cases, age-standardized incidence rate (ASIR), disability-adjusted life years (DALYs), and age-standardized DALY rate between 1990 and 2019 by region, etiology, age, and sex, and calculated the estimated annual percentage change (EAPC) of the rate to evaluate the epidemiological trends. Results: Globally, incident cases of CKD increased from 7.80 million in 1990 to 18.99 million in 2019, and DALYs increased from 21.50 million to 41.54 million. ASIR increased with an EAPC of 0.69 (95% uncertainty interval [UI] 0.49–0.89) and reached 233.65 per 100,000 in 2019, while the age-standardized DALY rate increased with an EAPC of 0.30 (95% UI 0.17–0.43) and reached 514.86 per 100,000. North Africa and the Middle East, central Latin America, and North America had the highest ASIR in 2019. Central Latin America had the highest age-standardized DALY rate, meanwhile. Almost all countries experienced an increase in ASIR, and over 50% of countries had an increasing trend in age-standardized DALY rate from 1990 to 2019. CKD due to diabetes mellitus type 2 and hypertension accounted for the largest disease burden with 85% incident cases and 66% DALYs in 2019 of known causes, with the highest growth in age-standardized DALY rate and a similar geographic pattern to that of total CKD. Besides, the highest incidence rate of total and four specific CKDs were identified in people aged 70 plus years, who also had the highest DALY rate with a stable trend after 2010. Females had a higher ASIR, while males had a higher age-standardized DALY rate, the gap of which was most distinctive in CKD due to hypertension. Conclusion: The disease burden of CKD remains substantial and continues to grow globally. From 1990 to 2019, global incident cases of CKD have more than doubled and DALYs have almost doubled, and surpassed 40 million years. CKD due to diabetes mellitus type 2 and hypertension contributed nearly 2/3 of DALYs in 2019 of known causes, and had witnessed the highest growth in age-standardized DALY rate. Etiology-specific prevention strategies should be placed as a high priority on the goal of precise control of CKD.

Burden of AML, 1990-2019: Estimates From the Global Burden of Disease Study

PURPOSE AML accounts for 80% of acute leukemia in adults. While progress has been made in treating younger patients in the past 2 decades, there has been limited improvement for older patients until recently. This study examines the global and European Union (EU) 15+ trends in AML between 1990 and 2019. METHODS We extracted age-standardized incidence rates (ASIRs), age-standardized death rates (ASMRs), and disability-adjusted life years, stratified by sex from the Global Burden of Disease Study database, and mortality-to-incidence ratio (MIR) were computed. Trends were compared using Joinpoint regression. RESULTS The findings show a global increase in AML incidence for both sexes from 1990 to 2019. In the EU15+ countries, most countries exhibited an increase in ASIR for both sexes. Joinpoint revealed that globally for male patients, ASIR steadily increased until 2010, remained stable until 2015 followed by a decline till 2019. Similar trends were observed in female patients. For ASMR, although there was an increase globally and in most EU15+ countries, there was a statistically significant decrease in mortality rates globally and in the majority of EU15+ countries in recent years. MIR improved in both sexes globally. On age stratification, AML burden was highest among older groups (55 years and older), while the lowest rates were observed in younger than 20 years. CONCLUSION The findings from our study indicate a global rise in AML incidence and mortality in both sexes and decrease in MIR from 1990 to 2019 suggesting a better survival. However, on Joinpoint analysis, there is no change in MIR in women in the past decade and past 4 years in men indicating plateau in survival trends despite recent advances.

Burden and trends of iodine deficiency in Asia from 1990 to 2019

ObjectivesUnderstanding iodine deficiency (ID) burdens and trends in Asia can help guide effective intervention strategies. This study aims to report the incidence, prevalence, and disability-adjusted life years (DALYs) of ID in 48 Asian countries during the period 1990–2019. Study designData on ID were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and estimated by age, sex, geographical region, and sociodemographic index (SDI). MethodsThe estimated annual percentage change (EAPC) was calculated to evaluate the changing trend of age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), and age-standardized DALYs rate (ASDR) related to ID during the period 1990–2019. ResultsIn Asia, there were 126,983,965.8 cases with 5,466,213.1 new incidence and 1,765,995.5 DALYs of ID in 2019. Between 1999 and 2019, the EAPC in ASIR, ASPR and ASDR were −0.6 (95% confidence interval [CI], −0.8 to −0.4), −0.9 (95% CI, −1.2 to −0.7), and −1.6 (95% CI, −1.8 to −1.5), respectively. Malaysia charted the largest decrease in ASIR, ASPR, and ASDR (82.4%, 85.3%, and 80.9% separately), whereas the Philippines and Pakistan were the only two countries that witnessed an increase in ASIR and ASPR. ID burdens were more pronounced in women, countries located to the south of the Himalayas, and low-middle SDI regions. ConclusionsThe incidence, prevalence, and DALYs of ID in Asia substantially decreased from 1990 to 2019. Women and low-middle SDI countries have relatively high ID burdens. Governments need to pay constant attention to the implementation and monitoring of universal salt iodization.

Gender, Age, and Regional Disparities in the Incidence and Mortality Trends of Infective Endocarditis in the United States Between 1990 and 2019

The incidence of infective endocarditis (IE) has increased globally in the past decades, including in the United States. However, little is known about the differences in trends across states, gender, and age groups within the United States. Using the Global Burden of Disease database, we analyzed the incidence and mortality trends of IE in the United States between 1990 and 2019 using Joinpoint regression analyses, and compared between states, gender, and age groups. The age-standardized incidence rate (ASIR) of IE in the United States increased from 10.2/100,000 population in 1990 to 14.4 in 2019. The increase in ASIR was greater among men than women (45.8% vs 34.1%). The incidence increase was driven by 55+ year-olds (112.7% increase), with rapid increases in the 1990s and early 2000s, followed by a plateau around the mid-2000s. In contrast, the incidence among 5-to-19-year-olds decreased by -36.6% over the 30-year period. The incidence increased among all age groups in the last 5years of observation (2015 to 2019), with the largest increase in 5-to-19-year-olds (3.3% yearly). The 30-year increase in ASIR was greatest in Utah (66.2%) and smallest in California (30.2%). The overall age-standardized mortality attributable to IE increased in the United States by 126% between 1990 and 2019 versus 19.6% globally. In conclusion, although the overall incidence and mortality of IE increased over the past 30years in the United States, there are significant differences between regions, gender, and age groups. These findings indicate unevenly distributed disease burden of IE across the nation.

The global, regional and national burden of type 2 diabetes mellitus in the past, present and future: a systematic analysis of the Global Burden of Disease Study 2019.

To report the global, regional, and national burden of type 2 diabetes mellitus (T2DM) in 2019, assess its trends in the past, and forecast its trends in the future. The main data source was the Global Burden of Disease 2019 database. We assessed the changes in T2DM burden from 1990 to 2019 with joinpoint regression analysis. Age-period-cohort analysis was used to forecast the T2DM incidence and mortality rate from 2020 to 2034. The burden of T2DM has increased from 1990 to 2019 generally. The low-middle socio-demographic index (SDI) region had the highest increase in age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), age-standardized mortality rate (ASMR), and age-standardized disability-adjusted life years (ASDR) due to T2DM. Nationally, the increase in ASIR (r=0.151, p=0.046) and the decrease in ASMR (r=0.355, p<0.001) were positively correlated with SDIs. In 2019, the global ASIR, ASPR, ASMR, ASDR due to T2DM were 259.9 (95% UI 240.3-281.4), 5282.9 (95% UI 4853.6-5752.1), 18.5 (95% UI 17.2-19.7), and 801.5 (95% UI 55477000-79005200) per 100,000 population, respectively. Additionally, the ASIR (r=0.153, p=0.030) and ASPR (r=0.159, p=0.024) of T2DM were positively correlated with SDIs, while ASMR (r=-0.226, p=0.001) and ASDR (r=-0.171, p=0.015) due to T2DM were negatively correlated with SDIs. The ASIR was estimated to increase to 284.42, and ASMR was estimated to increase to 19.1 from 2030 to 2034, per 100,000 population. Globally, the burden of T2DM has increased in the past and was forecast to continue increasing. Greater investment in T2DM prevention is needed.

Ten-year trends in incidence and prevalence of atrial fibrillation and flutter in Denmark according to demographics, ethnicity, educational level, and area of residence (2009-2018).

Atrial fibrillation is the most common cardiac arrhythmia and a major global health burden. Updated trends in the epidemiology of atrial fibrillation or flutter (AF) are needed. Using the Danish Heart Statistics, we investigated nationwide trends 2009-2018 in incidence rate and prevalence of AF according to age as well as age-standardized incidence rate (ASIR) and prevalence (ASP) of AF according to sex, ethnicity, educational level, and area of residence. Comparing year 2018 to 2009, we calculated stratum-specific ASIR ratios (ASIRR) and changes in ASP. During 2009-2015 the ASIR for AF increased for both men and women, followed by a decline from 2015-2018. Overall, this resulted in a 9% increase among men (ASIRR: 1.09, 95% CI: 1.06-1.12), but no change among women (ASIRR: 1.00, 95% CI: 0.97-1.04). The ASP increased by 29% among men and 26% among women. An increase in ASIR was observed in all ethnic groups except men of Far Eastern ethnicity. Lower educational level was associated with greater increases in both ASIR and ASP. ASIR and ASP differed slightly between the Danish regions but increased in all of them. During 2009-2018 the incidence and prevalence of AF in Denmark increased although the increase in incidence was transient among women. Factors associated with higher incidence were male sex, higher age, Danish and Western ethnicity as well as Middle Eastern/North African ethnicity among women, and lower educational level. Within Denmark, we observed only minor regional differences in AF incidence and prevalence.

Global, regional, and national trends of syphilis from 1990 to 2019: the 2019 global burden of disease study

BackgroundSyphilis is a sexually transmitted disease caused by Treponema pallidum, and the infection source is syphilis patients. This study aimed to estimate the incidence, mortality rate, and disability-adjusted life years (DALYs) of syphilis to improve the understanding of the current global situation of syphilis.MethodsThis study collected data on syphilis incidence, mortality, and DALYs from the 2019 Global Burden of Disease database.ResultsThe global number of incident cases and age-standardized incidence rate (ASIR) increased from 8,845,220 (95% UI: 6,562,510–11,588,860) in 1990 to 14,114,110 (95% UI: 10,648,490–18,415,970) in 2019 and 160.03/100,000 persons (95% UI: 120.66–208.1) to 178.48/100,000 persons (95% UI: 134.94–232.34), respectively. The estimated annual percentage change (EAPC) in the ASIR was 0.16 (95% CI: 0.07–0.26). The EAPC in the ASIR associated with high and high-middle sociodemographic indices increased. The ASIR increased among males but decreased among females, and the incidence peaked among males and females between the ages of 20 and 30 years. The EAPCs in the age-standardized death rate and age-standardized DALY rate decreased.ConclusionsThe incidence and ASIR of syphilis increased worldwide from 1990 to 2019. Only the regions with high and high-middle sociodemographic indices showed an increase in the ASIR. Moreover, the ASIR increased among males but decreased among females. The age-standardized death rate and DALY rate both declined worldwide. The increase in the global ASIR of syphilis is a challenge.

Global, regional, and national incidence and mortality of congenital birth defects from 1990 to 2019.

The study aims to estimate the trends in incidence and mortality of congenital birth defects at global, regional, and national levels from 1990 to 2019. Annual incident cases, age-standardized incidence rates (ASIRs), deaths, and age-standardized mortality rates (ASMRs) of congenital birth defects during 1990-2019 were collected from Global Burden of Diseases Study 2019. We calculated percentage of relative changes and estimated annual percentage changes (EAPCs) to quantify temporal trends, and explored potential influence factors of EAPCs using Pearson correlation. Globally, total incident cases and deaths of congenital birth defects were 8.52 million and 0.55 million in 2019. Congenital heart anomalies were the major category of congenital birth defects worldwide in 2019. From 1990 to 2019, the ASIR remained stable (EAPC=0.01, 95% CI -0.03 to 0.05), whereas the ASMR decreased (EAPC=-1.79, 95% CI -1.84 to -1.74). The most pronounced increase in ASIR occurred in low-middle socio-demographic index (SDI) regions (EAPC=0.03, 95% CI 0.01 to 0.06). The number of deaths increased by 14.49% in low SDI regions and the ASMR increased in Southern Sub-Saharan Africa (EAPC=0.17, 95% CI 0.02 to 0.33). Negative correlations of EAPCs in ASIRs and ASMRs with SDI and universal health coverage index values in 2019 were detected at national levels. Conclusions: Congenital birth defects are an important child health problem. There is urgent need to strengthen surveillance and detection of congenital birth defects, build and improve maternal and child healthcare capacity, and promote treatment and rehabilitation, especially in resource-limited countries. What is known: • Congenital birth defects were the fourth leading cause of death among children under 5years in 2019, accounting for nearly 10% of deaths. What is new: • In this study using data from the Global Burden of Disease Study, global incident cases, deaths, and age-standardized mortality rate (ASMR) of congenital birth defects decreased, whereas age-standardized incidence rate (ASIR) remained stable from 1990 to 2019. • From 1990 to 2019, the most pronounced increase in ASIR occurred in Oceania, and the ASMR increased by an average of 0.17% per year in Southern Sub-Saharan Africa.

The burden of liver cirrhosis and underlying etiologies: results from the Global Burden of Disease Study 2019.

Liver cirrhosis is a major health concern. Herein, we aimed to estimate the incidence, prevalence, and mortality of liver cirrhosis caused by specific etiologies for 204 countries and territories. The data were retrieved from the Global Burden of Disease Study 2019. The age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), age-standardized death rate, and estimated annual percentage changes were used to estimate the trends in incidence, prevalence, and mortality of liver cirrhosis by sex, region, country, and etiology between 2009 and 2019. From 2009 to 2019, the incident cases of liver cirrhosis increased by 16.7%, from 1.8 million (95% uncertainty interval: 1.5-2.1) to 2.1 million (1.7-2.5), and the prevalent cases increased from 1378.3 million (1275.1-1498.8) to 1691.0 million (1560.9-1845.5). Liver cirrhosis contributed to nearly 1.5 million (1.4-1.6) deaths in 2019, nearly 0.2 million more than in 2009. However, the age-standardized death rate fell from 20.71 (19.79-21.65) per 100,000 population in 2009 to 18.00 (16.80-19.31) per 100,000 population in 2019. In terms of sex, males showed higher ASIR, ASPR, and age-standardized death rate than females. Among the etiologies, the ASIR and ASPR of NAFLD increased markedly, and there was also a modest increase in ASIR and ASPR for HCV and alcohol use. In contrast, the ASIR and ASPR of HBV decreased considerably. Our finding suggests an increasing burden of liver cirrhosis worldwide but a declining attributed death. A high prevalence and still rising trend of NAFLD and alcohol use-etiology were found in patients with cirrhosis globally, although variation was found between regions/countries. These data indicate that efforts to reduce the associated burden need to be improved.

The Global Burden of Appendicitis in 204 Countries and Territories from 1990 to 2019.

Appendicitis is a common surgical emergency. This study aimed to estimate the worldwide burden and trends of appendicitis from 1990 to 2019. Data on appendicitis were derived from the Global Burden of Disease 2019. Incidence and disability-adjusted life-years (DALYs) data were analyzed at global, regional, and national levels and stratified by sex, age, and socio-demographic index. The estimated annual percentage change and relative change were used to assess changing trends. Pearson's correlation test was used to assess the correlation between different measures. Global incidence grew by 63.55% between 1990 and 2019, age-standardized incidence rate climbed by an estimated percentage change of 0.58 per year, whereas the number of DALY declined by 31.93% during the same period, with an estimated annual percentage change of -2.77. In 2019, the areas of Andean Latin America and the Caribbean had the highest age-standardized rates of incidence and DALYs. While South Asia saw the largest increase in age-standardized incidence rates, Andean Latin America saw the biggest decline in age-standardized rates of incidence and DALYs. At the national level, Bangladesh, Bhutan, and Peru were the top three countries in terms of age-standardized incidence rates in 2019, and Honduras, Haiti, and the Central African Republic held the highest age-standardized DALY rates. Ethiopia experienced the most age-standardized incidence rate increase, and Peru saw the largest decline in age-standardized rate of incidence and DALYs. Significant negative correlations between age-standardized DALY rates and socio-demographic index, between estimated annual percentage change and age-standardized incidence rates, were observed at the national level. Appendicitis remains a major global health concern. Although the trends in DALYs decreased, the burden of incidence increased from 1990 to 2019. Policymakers should create health policies adapted to local conditions to manage the burden of appendicitis globally.

Lifestyle and Socioeconomic Transition and Health Consequences of Breast Cancer in the East Asia Region, From 1990 to 2019.

BackgroundDue to its higher prevalence and heterogeneity, female breast cancer (BC) is the widest disease throughout the world. We sought to assess the epidemiological and sociodemographic transitions of BC and to identify the potential risk factors attributed to burden of BC in East Asia.MethodsAt the regional level of East Asia and at a national level of East Asian countries, we investigated the burden of the incidence of female BC, mortality, and disability-adjusted life years (DALYs) in 2019 and assessed the epidemiological, socioeconomic, and health-linked disparities in incidence of BC and mortality over a 30-year period. The changes in BC’s mortality and DALYs between 1990 and 2019, attributable to varying risk factors, were evaluated in different age groups.ResultsIn 2019, the incidence of and mortality from and DALYs of BC were estimated to be 382,321 (95% UI: 303,308–477,173) incidence cases [age-standardized rate (ASR) of 35.69 per 100,000; 28.32–44.54], 98,162 (79,216–120,112) deaths (ASR of 9.12; 7.36–11.13), and 3,024,987 (2,477, 984–3,659,370) DALYs with an ASR of 282.15 (230.81–341.19) in 2019. It was also observed that out of four most representative locations of East Asia, two (China and Japan) showed more than 60% increase in age-standardized incidence rate between 1990 and 2019. While only Japan females showed a significant rise of 15.3% (95% UI: 2.3–28) in ASR of death and 12.6% (95% UI: 0.5–26.9) in ASR of DALYs between 1990 and 2019. Inclusively, 88 and 81% variations were explained in the incidence of BC and death due to change in sociodemographic index (SDI) in 2019, in East Asia. The highest positive percent changes in death and DALYs between 1990 and 2019 were attributable to high body mass index (BMI), high fasting plasma glucose (FPG), and alcohol consumption in East Asia.ConclusionThe burden of death and disability from female BC is the result of multiple risk factors, mainly due to behavioral and metabolic risk factors. The increase of the incidence is related to the westernized lifestyle and diet habits and the improvement of screening and diagnosis techniques in the recent years, whereas the increase in DALYs is mainly attributed to high BMI, high FPG, alcohol use, and high diet in red meat.

Spatiotemporal trends of the global burden of melanoma in 204 countries and territories from 1990 to 2019: Results from the 2019 global burden of disease study.

This study aimed to estimate the latest magnitudes and temporal trends of melanoma burden at the national, regional, and global levels. The data on melanoma incidence, deaths, and disability-adjusted life-years (DALYs) in 204 countries and territories between 1990 and 2019 came from the Global Burden of Disease 2019 Study. Estimated annual percentage change (EAPC) was calculated to depict the temporal trends and Spearman rank correlation was used to analyze the influential factors of EAPC. From 1990 to 2019, the incident cases of melanoma increased by 170% to 289,950, death increased by 90% to 62,840, and DALYs increased by 67% to 1,707,800 globally. The age-standardized incidence rate (ASIR) of melanoma increased globally by an average of 1.13 [95% confidence interval (CI): 0.93–1.32], while the age-standardized rates of death and DALYs both declined with the EAPC of −0.27 (95% CI: −0.36 to −0.19) and −0.49 (95% CI: −0.57 to −0.41). In 2019, the highest burden of melanoma was observed in Australasia, followed by high-income North America and Europe regions, which all presented an incremental growth in ASIR. The positive association between the EAPC in ASIR and socio-demographic index (SDI) in 2019 (ρ = 0.600, P < 0.001) suggested that countries with higher SDI have experienced a more rapid increase in ASIR of melanoma. In conclusion, the burden of melanoma is increasing globally but differed greatly across the world. Notably, the high burden areas are facing a continuing increase in incidence, which implies more targeted strategies should be taken for reducing the increasing melanoma burden.

Non-Melanoma Skin Cancer Distribution in the Russian Federation

Background: Non-melanoma skin cancer (NMSC) incidence has been increasing steadily around the world. The aim of the study is to describe geographic trends in incidence and mortality of NMSC in Russia between 2007 and 2017 and compare findings to other European countries. Methods: We used geospatial analysis to map the incident cases and descriptive statistical analysis to analyze trends. Additionally, we assessed the relationship between ethnicity, geographic latitude/longitude, and NMSC incidence/mortality rates. We retrospectively analyzed the data from the Moscow Oncology Research Institute, Ministry of Health of the Russian Federation, for 2007–2017. Routine methods of descriptive epidemiology were used to study incidence and mortality rates by age groups, years, and jurisdictions (i.e., Federal Districts and Federal Subjects). Results: In total, 733,723 patients were diagnosed with NMSC in Russia over the period 2007–2017, of whom 63% were women. The overall age-standardized incidence and mortality rates were 29.64/100,000 and 0.70/100,000, respectively. There was a consistent increase in age-standardized incidence rates over the study period, with a decreasing mortality rate. Geographic mapping revealed north-to-south and east-to-west gradients for NMSC. Conclusions: This study demonstrated longitudinal trends for NMSC incidence in Russia documenting that skin phototype, latitude/longitude, climate zones, and cultural practices remain dominant risk factors defining the epidemiology of NMSC. Moreover, this work identified several regions in the country (i.e., Republic of Adygea, Samara, Krasnodar Krai, etc.), where patient education/sun awareness campaigns will be useful to help reduce the risk of this malignancy.
