Trends and disparities in age, gender, ethnoracial background, and urbanization status in adult mortality due to thoracic aortic aneurysm: a retrospective nationwide study in the United States

Introduction: Thoracic aortic aneurysms (TAA) are a significant health concern, with the true prevalence likely underestimated due to undiagnosed cases. Outcomes in TAA are influenced by factors like age, gender, and comorbidities such as hypertension. This study examines mortality trends and disparities associated with TAA in US adults. Methodology: This study analyzed death certificates from 1999 to 2020 using the CDC WONDER Database to identify TAA-related deaths in individuals aged 25 and older using ICD-10 codes I71.1 and I71.2. Age-adjusted mortality rates (AAMRs) per 1,000,000 and annual percent changes (APCs) were calculated and stratified by year, gender, age group, race/ethnicity, region, and urbanization status. Results: Between 1999 and 2020, 47,136 TAA-related deaths were reported among US adults. The AAMR decreased from 16.2 to 8.2 per 1,000,000, with a significant decline from 1999 to 2013 (APC: −5.00; 95% CI: −5.54 to −4.54; P<0.001). Older adults had the highest AAMRs at 44.6 per 1,000,000. Men had higher AAMRs than women (11.2 vs. 9). AAMRs were highest among non-Hispanic (NH) Black (11), followed by NH White (10.3), NH Asian or Pacific Islander (9.5), NH American Indian or Alaska Native (7.8), and Hispanic (5.2) populations. Non-metropolitan areas had higher AAMRs than metropolitan areas (11 vs. 9.8). Conclusions: The analysis showed a significant decline in TAA mortality since 1999, with recent stabilization. However, disparities persist, with higher AAMRs among men, older adults, NH Black adults and non-metropolitan residents, highlighting the need for targeted and equitable interventions.

Trends in Hepatocellular Carcinoma Mortality Rates in the US and Projections Through 2040

ImportanceThe burden of liver cancer varies worldwide. An upward trend in both hepatocellular carcinoma (HCC) incidence and mortality in the past 2 decades has been observed.ObjectiveTo assess observed HCC-related age-standardized mortality rates (ASMRs) in the US for 2006 to 2022 and provide ASMR projections through 2040.Design, Setting, and ParticipantsThis cross-sectional study used data from the National Vital Statistics System, which is accessible through the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research website. Data on deaths attributed to HCC (from January 1, 2006, to December 31, 2022) were obtained for adults 25 years or older and were stratified by liver disease etiology, age, sex, and race and ethnicity. Etiologies included alcohol-associated liver disease (ALD), hepatitis B virus (HBV), hepatitis C virus (HCV), and metabolic dysfunction–associated steatotic liver disease (MASLD).Main Outcomes and MeasuresThe main outcomes were (1) observed ASMRs of HCC per 100 000 persons using Joinpoint regression (National Cancer Institute) to assess trends during 2006 to 2022 and (2) ASMRs projected for 2023 to 2040 using Prophet and AutoARIMA modeling.ResultsThis study included 188 280 HCC-related deaths from 2006 to 2022. Most deaths occurred among males (77.4%). The annual percentage change was 4.1% (95% CI, 2.2% to 7.7%) for 2006 to 2009 and decreased to 1.8% (95% CI, 0.7% to 2.0%) for 2009 to 2022, with an overall observed ASMR of 5.03 per 100 000 persons in 2022 and a projected ASMR of 6.39 per 100 000 persons by 2040, with consistent trends for both sexes. By etiology, ASMRs decreased for HCV- and HBV-related mortality but increased for ALD- and MASLD-related mortality. In 2022, MASLD surpassed HBV as the third-leading cause of HCC-related death and was projected to overtake HCV in 2032 as the second-leading cause; ALD was projected to be the leading cause of HCC-related death in 2026. In 2022, the ASMR was higher among individuals aged 65 years or older compared with those aged 25 to 64 years (18.37 vs 1.79 per 100 000 persons). The American Indian or Alaska Native population had the largest increase in projected ASMR by 2040 (14.71 per 100 000 persons) compared with the Asian population (3.03 per 100 000 persons).Conclusions and RelevanceIn this cross-sectional study, ASMRs for ALD- and MASLD-related HCC death increased rapidly from 2006 to 2022; ALD-related HCC was projected to be the leading cause by 2026, with MASLD as the second-leading cause by 2032. These findings may serve as a reference for public health decision-making and timely identification of groups at high risk of HCC death.

Projected epidemiological trends and burden of liver cancer by 2040 based on GBD, CI5plus, and WHO data.

Incidence of liver cancer as one of the most common cancers worldwide and become the significant contributor for the mortality among cancer patients. The disease burden, risk factors, and trends in incidence and mortality of liver cancer globally was described subsequently estimated the projections of liver cancer incidence or mortality by 2040. Data regarding age-standardized incidence and mortality rates for liver cancer was obtained from multiple databases, including GLOBOCAN 2020, CI5 volumes I-XI, WHO mortality database, and Global Burden of Disease (GBD)-2019. Concentrating on worldwide variations, this thorough analysis offers insights into patterns of incidence and mortality based on gender and age. Our findings encompass significant indicators, including age-standardized rates (ASRs), average annual percentage change (AAPC), and future projections extending up to the year 2040. Liver cancer holds the sixth position in terms of most frequently diagnosed cancers and stands as the sixth leading cause of cancer-related deaths worldwide in 2020, accounting for 905,677 new cases and 782,000 fatalities. Additionally, liver cancer contributed to 12,528,421 age-standardized disability-adjusted life years (DALYs), with an age-standardized DALYs rate of 161.92 in 2019 worldwide. The age-specific incidence rates exhibited significant variations across different regions, showing a fivefold difference in males and females. A significant increase in incidence was observed in North Europe and Asia, while North African countries reported a higher mortality burden (ASR, 10 per 100,000) compared to developed countries. Since last few years, the incidence and mortality rates have increased and attained Annual Average Percentage Change (AAPC) incidence rate of 7.7 (95% CI 3.9-11.6) for men and the highest AAPC mortality rate of 12.2 (95% CI 9.5-15.0) for women. In 2019, Western Europe emerged as the high-risk region for DALYs related to smoking and alcohol consumption, while high-income North America carried a high risk for DALYs associated with a high body-mass index. The projected trend indicates a surge in new liver cancer incident cases, expected to rise from around 905,347 to an estimated 1,392,474 by 2040. This study described the evidence pertinent to higher incidence trends in liver cancer, particularly among both young and older adults, encompassing males and females, as well as those who are HIV-infected and HBsAg positive. A significant rise in the young population poses a significant public health concern that warrants attention from healthcare professionals to prioritize the promotion of health awareness and the development of effective cancer prevention strategies, particularly in many developing countries.

Evolution of orthodontic services in the Brazilian Unified Health System: a time series analysis (2011-2022).

Although malocclusion is the third most prevalent oral health condition, orthodontics is not part of the minimum list of mandatory specialties to be offered in the Dental Specialty Centers of the Brazilian public health system, but rather as optional. Since the acknowledgment of this field as a part of the Brazilian Unified Health System (SUS), access to orthodontic procedures has become optional by municipal governments. Therefore, this study analyzed the evolution of orthodontic procedure provision within SUS from 2011 to 2022. We conducted a retrospective observational study of time series analysis trends on the number of orthodontic procedures and municipalities offering them. The presentation of findings followed the recommendations of the Reporting of Studies Conducted using Observational Routinely Collected Data. Secondary data from 2011 to 2022 were collected from the SUS Department of Informatics. Orthodontic procedures were organized by year, region, state, and municipality. The study applied descriptive analyses, and the Prais-Winsten generalized linear regressions for time series analysis. The quantity of municipalities offering orthodontic procedures have shown a small increasing during period analyzed (from 128 to 157). Northeast and South macro-regions have increased consistently the municipalities with orthodontic offering. All regions showed stable trends for each procedure, except for the South, which exhibited increasing rates of space maintainer placement (Annual Percentage Change (APC): 72.95; 95% CI: 31.6, 127.3) and maintenance sessions (APC: 15.40; 95% CI: 4.5, 27.5). The study showed decreasing trends for appliance removal in the South (APC: -38.07; 95% CI: -47.1, -27.5) and Northeast (APC: -25.19; 95% CI: -36.5, -11.9) regions. From 2011 to 2022, there was a small increase in number of municipalities offering orthodontic procedures in the Brazilian public health system, in addition to a stationary trend for almost all types of procedures.

Trends of extreme hyperbilirubinemia related infant mortality in select European countries (1990-2019).

Limited data exist on population-level mortality outcomes related to extreme neonatal hyperbilirubinemia (EHB) and this study examines trends in annual infant mortality rate (IMR) attributed to hemolytic and perinatal jaundice among Germany, France, Italy, Portugal, Greece and Spain from 1990 to 2019. Data on annual incident cases and disability-adjusted life years were collected from the 2019 Global Burden of Disease study. Live birth cohort data were sourced from UN World Population Prospects. We quantified temporal trends, with relative percent changes. Average annual percent changes (AAPCs) were evaluated using the Joinpoint Regression Program. EHB-related infant mortality decreased from 21.4 (95%CI: 16.1, 27.1) in 1990 to 4.2 (95%CI: 1.9, 7.6) per million live births in 2019. Germany demonstrated lowest AAPC of -3.2% (95% CI: -3.8, -2.5), while Portugal had the highest AAPC of -8.6% (95% CI -11.9, -5.1) in reducing infant mortality due to EHB. There were distinct divergences in the trajectories of declining EHB mortality among the studied countries. This study highlights a significant decline in infant mortality due to extreme hyperbilirubinemia, emphasizing the need for national surveillance and tailored guidelines to prevent bilirubin induced neurological damage. This cross-sectional analysis revealed a marked decline in infant mortality rates attributed to extreme hyperbilirubinemia across the selected European countries. The rates of decline varied significantly between countries, demonstrating notable heterogeneity in mortality trends when stratified by age at death. Implementing data-driven surveillance systems can optimize the alignment of equitable healthcare services, strengthen accountability measures, and identify critical operational inefficiencies. In the European Union, country-specific hyperbilirubinemia guidelines should be reinforced to ensure effective screening and post-discharge follow-up protocols that are tailored to risk burden and available healthcare resources.

Global, regional and country-specific burden of patella, tibia or fibula, or ankle fractures and its prediction to 2035: findings from global burden of disease study 2019.

Bone fractures are a global public health issue and a major source of significant illness and financial hardship. However, to date, there is limited research on patella, tibia or fibula, or ankle fractures (FPTFA) disease burden. Using the framework of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, we conducted temporal trends of disease burden, effects of sex and socio-demographic index (SDI) on age standardized prevalence rate (ASPR) and age-period-cohort model. Machine learning models were built to predict the ASPR of FPTFA in 2035. In 1990 and 2019, the top three of all fractures with the highest ASPR was FPTFA. Globally, in 2019, there were 13529.45million (95%UI: 11811.02, 15642.25), 9198.67million (95%UI: 8518.9, 10009.91) and 77.54million (95%UI: 34.09, 149.9) prevalent cases of fracture attributable to fall, transport injury and mechanical external force, respectively. The number of fracture prevalence and years lived with disability (YLDs), and ASPR were higher in males than in females. From 1990 to 2019, most of GBD regions showed a downward trend in average annual percent change (AAPC) of ASPR attributable to transport injuries, High-income Asia Pacific had the highest decline (AAPC= -1.81%, 95%CI: -1.89% to -1.74%). However, an upward trend in East Asia was observed (AAPC = 1.60%, 95%CI: 1.48-1.73%). With increasing SDI, the ASPR for FPTFA attributed to the fall and mechanical external force slowly increased and then turned downward, especially in high-income and high-SDI countries. The longitudinal age curve suggested that the attributed rate was increased for the three sites of lower limb fractures. The best predictive models for FPTFA caused by falls, transport injuries and mechanical external force were autoregressive integrated moving average model (ARIMA) (0,2,1), ARIMA (2,0,1) and ARIMA (0,2,2), with R2 of 0.96, 0.78 and 0.94, respectively. By 2035, ASPR for the fall-related FPTFA will continue to rise rapidly, whereas the ASPR of the transport injury-related FPTFA will gradually decrease. FPTFA attributed to the falls is the dominant type and the burden and trends of the fall-related FPTFA are substantial. Fall prevention and access to treatment are crucial for reducing FPTFA burden.

Global burden associated with rare infectious diseases of poverty in 2021: findings from the Global Burden of Disease Study 2021.

Rare infectious diseases of poverty (rIDPs) involve more than hundreds of tropical diseases, which dominantly affect people living in impoverished and marginalized regions and fail to be prioritized in the global health agenda. The neglect of rIDPs could impede the progress toward sustainable development. This study aimed to estimate the disease burden of rIDPs in 2021, which would be pivotal for setting intervention priorities and mobilizing resources globally. Leveraging data from the Global Burden of Disease Study 2021, the study reported both numbers and age-standardized rates of prevalence, mortality, disability-adjusted life-years (DALYs), years lived with disability, and years of life lost of rIDPs with corresponding 95% uncertainty intervals (UIs) at global, regional, and national levels. The temporal trends between 1990 and 2021 were assessed by the joinpoint regression analysis. A Bayesian age-period-cohort model was used to project the disease burden for 2050. In 2021, there were 103.76 million (95% UI: 102.13, 105.44 million) global population suffered from rIDPs with an age-standardized DALY rate of 58.44 per 100,000 population (95% UI: 42.92, 77.26 per 100,000 population). From 1990 to 2021, the age-standardized DALY rates showed an average annual percentage change of - 0.16% (95% confidence interval: - 0.22, - 0.11%). Higher age-standardized DALY rates were dominated in sub-Saharan Africa (126.35 per 100,000 population, 95% UI: 91.04, 161.73 per 100,000 population), South Asia (80.80 per 100,000 population, 95% UI: 57.31, 114.10 per 100,000 population), and countries with a low socio-demographic index. There was age heterogeneity in the DALY rates of rIDPs, with the population aged under 15years being the most predominant. Females aged 15-49years had four-times higher age-standardized DALY rates of rIDPs than males in the same age. The projections indicated a slight reduction in the disease burden of rIDPs by 2050. There has been a slight reduction in the disease burden of rIDPs over the past three decades. Given that rIDPs mainly affect populations in impoverished regions, targeted health strategies and resource allocation are in great demand for these populations to further control rIDPs and end poverty in all its forms everywhere.

Prednisolone impairs trabecular bone score changes in adolescents with 21-hydroxylase deficiency.

Individuals with 21-hydroxylase deficiency (21OHD) require lifelong glucocorticoid (GC) therapy, which increases their risk of fragility fractures. However, fractures in GC-treated individuals can occur at normal bone mineral density (BMD) levels, suggesting an alteration in the bone microarchitecture. To evaluate trabecular bone microarchitecture and its changes in adolescents with 21OHD. We enrolled 38 adolescents with 21OHD for whom complete clinical data and baseline and follow-up lumbar spine bone mineral density (LSBMD) measurements were available. The mean duration was 1.5 ± 0.6 years. Trabecular bone score (TBS), an indirect measurement of bone microarchitecture, was analyzed using iNsight™ software version 3.0. Impaired BMD and TBS were defined at Z-scores ≤ -1.5. At baseline, participants (55% female; 68% salt-wasting type; mean age, 15.2 ± 3.8 years; bone age, 17.5 ± 2.8 years; mean GC dose, 18.5 ± 6.5 mg/m2/day) had the prevalence of impaired BMD and TBS of 5% and 18%, respectively. During follow-up, adolescents with 21OHD receiving prednisolone showed a lower annual percentage change in TBS than those who received hydrocortisone (p = 0.028). A stepwise regression analysis showed that body mass index percentile (p < 0.001) and testosterone concentration (p = 0.002) were independent positive predictors of the baseline TBS Z-score, whereas prednisolone use was the only negative predictor of the annual percentage change in TBS (p = 0.002). Adolescents with 21OHD have a high prevalence of impaired bone microarchitecture. Furthermore, prednisolone therapy is associated with impaired bone microarchitecture development, suggesting that hydrocortisone may better preserve bone microarchitecture and should be considered the first-line treatment for this population.

Total Gastrectomy for Gastric Malignancy: Trends Over 15 Years in Major Morbidity, Mortality, and Patient Selection From The National Surgical Quality Improvement Program.

We examined trends in major morbidity and mortality following total gastrectomy for malignancy in a national cohort. The National Surgical Quality Improvement Program was used to identify patients who underwent total gastrectomy for malignancy from 2007 to 2021. Joinpoint regression was used to determine annual percent changes (APCs) in thirty-day postoperative major morbidity, mortality, and length of stay (LOS). Major morbidity included deep and organ space surgical site infection, venous thromboembolism, cardiac event, pneumonia, acute renal failure, sepsis, and respiratory failure. Of 3515 patients, the median age was 65 years (IQR = 55-73), 59% were male, and 57.9% were White. Major morbidity was 23%, which did not change over time (APC = -1.4, 95% CI = -3.4 to 0.58), nor were there changes in individual morbidities with time. The most common morbidities were organ space surgical site infection (9.2%) and pneumonia (8.5%). Mortality rate in the study cohort was 2.7% and did not change (APC = -6.2, 95% CI = -13.0 to 1.1). LOS (median 9 days) also did not vary with time (APC = -2.3, 95% CI = -7.8 to 3.9). There was an increase in patients with diabetes (21.6% vs. 11.2%, p < 0.05), BMI ≥ 30 (31.1% vs. 18.2%, p < 0.05), and ASA IV-V status (11.6% vs. 3.5%, p < 0.05). Morbidity and mortality following total gastrectomy for malignancy have not significantly changed over the last fifteen years. While this may in part be explained by increased patient comorbidity, efforts should be made to improve patient selection and mitigate postoperative complications to allow for timely adjuvant therapies.

Burden of Parkinson's disease in Central Asia from 1990 to 2021: findings from the Global Burden of Disease study.

Central Asia is known to face various ecological challenges that constitutes major risk factors for Parkinson's disease (PD). This study examines the burden of PD in Central Asia, a region where data on neurological disorders is notably sparse. Building on the latest Global Burden of Disease Study (GBD 2021), this study investigates the Years of Life Lost (YLLs), Years Lived with Disability (YLDs), and Disability-Adjusted Life Years (DALYs) associated with PD in Central Asia and its countries from 1990 to 2021. The authors calculated average annual percent change (AAPC) to analyze trends, and compared individual country estimates to global figures. Additionally, incorporating data from the World Bank, both Bayesian hierarchical and non-hierarchical frequentist regression models were employed to assess their impact on DALYs. The DALYs varied across the study period, primarily driven by YLLs. While YLLs showed a uniform trend, YLDs were mostly incremental. Kazakhstan had the highest estimates across all metrics and was the only country aligned with global patterns. Age- and sex-specific estimates revealed substantial variations, with notably high figures found in male subjects from Tajikistan. The YLLs, YLDs, and DALYs for Kazakhstan, Uzbekistan, and Turkmenistan saw a significant increase in AAPCs. In contrast, Kyrgyzstan and Tajikistan saw declines, likely attributable to civic conflict and inter-country differences in population structure. Further comparison of DALY trends revealed significant deviations for all countries from the global pattern. This study showed an overall increase in PD burden from 1990 to 2021. These findings underscore the need for targeted strategies to reduce PD burden, with a particular focus on Kazakhstan. Integrating historical information is crucial for discussing the plausible mechanisms in studies sourced from the GBD.

Abstract 4127417: Trends in Atherosclerotic Cardiovascular Disease Related Mortality Among Older Adults in the United States From 1999-2021

Background: Atherosclerotic cardiovascular disease (ACVD) is the leading cause of mortality in the U.S, and increasing age is one of the greatest risk factors for the development and prognosis of ACVD. However, ACVD-related mortality trends in older adults have not yet been established. Aims: This study aims to highlight the annual trends and demographic differences in ACVD-related mortality among older adults in the U.S. from 1999 to 2021. Methods: The CDC WONDER multiple-cause of death database was examined from 1999 to 2021 for ACVD-related mortality in adults &gt;65 years of age. Age-adjusted mortality rates (AAMRs) per 100,000 persons was calculated. Trends and annual percent changes (APCs) were calculated, and subsequently stratified by overall, sex, race/ethnicity, urbanization status, and census region. Results: Between 1999 and 2021, 9,307,495 ACVD-related deaths occurred among older adults in the U.S. AAMRs decreased from 1370.7 in 1999 to 803.5 in 2014 (APC, -3.64 [-3.89 to -3.46]), after which it gradually decreased to 741.3 in 2019 (APC, -1.24 [-2.54 to 0.19]), and then increased to 841.5 in 2021 (APC, 7.00 [3.92 to 9.18]). Men had consistently higher AAMRs than women from 1999 (AAMR men: 1754.1 vs women: 1122.2) to 2021 (AAMR men: 1169.6 vs women: 599.6). Non-Hispanic (NH) Black or African American older adults had the highest AAMR in 2020 (886.1), followed by NH White (849.4), NH American Indian/Alaska Native (752.5), Hispanics or Latino (718.3) and NH Asian or Pacific Islanders (494.4). AAMR also varied substantially by region (overall AAMR until 2020: Midwest 875.1; South 872.2; Northeast 801.0; West 789.2), and rural areas had higher ACVD-related mortality (993.5) than urban regions (954.7). Figure 1. Conclusion: Following a progressive decrease until 2019, ACVD-related mortality in U.S. older adults demonstrated a sharp increase in mortality in 2020 and 2021. The highest AAMRs were observed among Black or African American adults and men, and among patients living in the Midwestern and non-metropolitan areas. A targeted approach, with tailored strategies is required to counter the recent surge in ACVD-related mortality in older adults in the U.S.

Abstract 4131486: Cardiovascular Mortality in Children and Young Adults: Trends and Demographic Differences in the United States, 1999 to 2021

Background: Cardiovascular disease (CVD) mortality in the U.S. younger population is on the rise. However, limited data is available on CVD-related mortality trends in this population. Aim: This study aimed to assess the temporal trends and demographic differences in CVD-related mortality among the U.S. youth. Methods: The CDC WONDER dataset was analyzed from 1999-2021 for CVD-related mortality in children and young adults (age &lt;25 years). Socio-demographic data including gender, race/ethnicity, urbanization status and census region was acquired. Age adjusted mortality rates (AAMR) per 100,000 persons and annual percent changes (APCs) with 95% confidence interval (CIs) were calculated. Results: Between 1999-2021, a total 54,283 CVD-related deaths occurred among the youth in the U.S. The overall AAMR declined from 1999-2008 (APC, -1.15 [-3.4 to 0.53]), followed by sharp decrease from 2008-2012 (APC, -3.28 [-4.68 to 0.86]). The AAMR continued to decrease steadily from 2012 to 2019 (APC: -1.20, [-3.76 to -0.06]), followed by a sharp increase in from 2019 to 2021, (APC, 3.03 [-0.66 to 5.12]). Males consistently had higher AAMRs than females from 1999 (AAMR males: 2.99 vs females: 2.3) to 2021 (AAMR males: 2.39 vs females: 1.74). Non-Hispanic (NH) Black or African Americans had the highest AAMR in 2020 (3.68), followed by NH Whites (1.71), Hispanic or Latinos (1.59), and Asian and Pacific Islanders (1.2). AAMRs also showed significant variations across different regions (overall AAMR West 1.81; Northeast 1.93; Midwest 2.3; South 2.69). Metropolitan areas (2.23) consistently had lower mortality rates than nonmetropolitan areas (2.59). Conclusion: Our analysis revealed that CVD-related mortality in the youth declined from 1999-2019, followed by an increase in 2020 to 2021. Highest mortality rates were seen in males, Black or African Americans, Western region of the U.S, and nonmetropolitan areas. Tailored interventions are necessitated to decrease the burden of CVD-related mortality in these demographics among children and young adults in the United States.

Abstract 4128457: Trends in Hypertension-Related Mortality Among Younger Adults in the United States From 1999-2021

Background: The U.S. population has seen a dramatic increase in the burden of hypertension (HTN) among younger adults. However, HTN-related mortality trends among younger adults have not been investigated. Aim: We examined the trends and demographic differences in HTN-related mortality among younger adults in the U.S. Methods: Data from the CDC WONDER database was examined from 1999 to 2021 for HTN-related mortality in adults between 15 to 45 years of age. The International Statistical Classification of Diseases and Related Health Problems-10th Revision (ICD-10) codes employed were as follows: I10-I15 (hypertensive diseases). Age-adjusted mortality rates (AAMRs) per 100,000 persons and annual percent changes (APCs) with 95% confidence intervals (CIs) were calculated and stratified by year, sex, race/ethnicity, urbanization status and census region. Results: Between 1999 and 2021, 201,860 HTN-related mortalities occurred among younger adults in the U.S. The AAMR increased from 2.8 in 1999 to 5.0 in 2001 (APC, 35.3 [20.6 to 44.5]), after which it steadily increased to 9.4 in 2019 (APC 3.1, [2.7 to 3.5]), and sharply increased to 13.9 in 2021 (APC 22.3; 95% CI 15.1 to 26.4). Men had consistently higher AAMRs than women from 1999 (AAMR men: 3.6 vs women: 1.9) to 2021 (AAMR men: 18.9 vs women: 8.8). Non-Hispanic (NH) Black or African American young adults had the highest AAMR in 2020 (30.2), followed by NH American Indian/Alaska Natives (29.6), NH White (9.9), Hispanics or Latino (9.3) and NH Asian or Pacific Islanders (5.0). AAMR also varied substantially by region (overall AAMR: South 9.3; Midwest 6.4; West 5.8; Northeast 5.4), and rural areas had higher HTN-related mortality (8.5) than their urban counterparts (7.0). Figure 1. Conclusion: Following a steady increase until 2019, HTN-related mortality increased among young adults between 2020 and 2021. The highest AAMRs were observed among men and Black or African American young adults, and people residing in the Southern and non-metropolitan areas. This emphasizes the necessity of tailored interventions to mitigate the burden and reduce the current disparities in HTN-related mortality among young adults in the U.S.

Abstract 4128261: Heart Failure-Associated Sudden Cardiac Death: Trends and Demographic Differences in the United States Adults, 1999 to 2020

Background: The US population has seen a dramatic increase in the burden of heart failure (HF) and sudden cardiac death (SCD) mortality. SCD is one of the prominent causes of mortality in HF patients. However, HF-associated SCD-related mortality trends have not been established yet. Aims: This study aims to highlight the annual trends and demographic differences in HF-associated SCD mortality among adults in the U.S from 1999-2020. Methods: The CDC WONDER multiple-cause of death database was examined from 1999 to 2020 for HF-associated SCD mortality in adults over the age of 25. Age-adjusted mortality rates (AAMRs) per 1,000,000 persons was calculated. Trends and annual percent changes (APCs) were assessed overall and stratified by sex, race/ethnicity, urbanization status, and census region. Results: Between 1999 and 2020, 39,660 HF-associated SCD-related deaths occurred among US populations. Following a reduction from 10.9 in 1999 to 6.8 in 2018 (APC, -2.5 [-2.8 to -2.3]), AAMR increased to 8.2 in 2020 (APC, 10.3 [3.6 to 13.7]) in the overall population. Men had consistently higher AAMRs than women from 1999 (AAMR men: 15.1 vs women: 7.9) to 2020 (AAMR men: 11.3 vs women: 5.6). Non-Hispanic (NH) Black or African Americans had the highest AAMR (14.0), followed by NH Whites (8.3), and Hispanics or Latinos (3.4). Southern region had the highest AAMR (10.4), followed by Midwest (9.6), West (5.8), and Northeast (5.8). Moreover, rural areas had consistently higher AAMR (14.6) than urban areas (6.9). Conclusion: Following a steady decline until 2018, HF-associated SCD mortality in adults increased between 2018 and 2020. The highest AAMRs were observed among Black or African American adults and men, and patients living in the Southern and non-metropolitan areas. Tailored strategies focusing specifically on arrhythmic events and related mortality in HF patients are needed to address the recent surge in mortality rates among these demographics.

Abstract 4120332: RISING TRENDS IN ISCHEMIC HEART DISEASE RELATED MORTALITY AMONG OLDER ADULTS WITH SLEEP APNEA IN THE UNITED STATES FROM 1999 TO 2021

Introduction: Sleep apnea (SA) is often underrecognized and undertreated despite its high prevalence in the adult population and its association with adverse cardiovascular outcomes. There are limited estimates of national trends on cardiovascular mortality in older patients with sleep apnea. We aimed to assess the sex and race-related trends of ischemic heart disease (IHD) mortality in the older adults with SA using a large population-based database. Methods: We utilized the Centers for Disease Control and Prevention Wide-Ranging, Online Data for Epidemiologic Research (CDC WONDER) database which provides information from death certificates of all US residents according to the International Classification of Diseases, Tenth Revision (ICD-10). The demographic and mortality data were obtained for the United States population &gt;65 years from 1999 to 2021. Ischemic heart disease (ICD-10 codes I20-I25) was listed as the underlying cause of death, and SA (G47.3) as a contributing cause of death. Age adjusted mortality rates (AAMRs) per 1,000,000 population were calculated by standardizing deaths to the year 2000 US population. We used Jointpoint Regression Program to analyze temporal trends in mortality from 2000 to 2021. Average annual percentage change (AAPC) with 95% CI were calculated to examine trends in AAMR over time. Results: Overall, AAMR of IHD mortality for patients with SA increased from 7.9 per 1,000,000 (95% CI, 6.9-8.8) in 1999 to 53.4 per 1,000,000 (95% CI, 51.4-55.4) in 2021 with an AAPC of 9.1% per year (95% CI, 8.8-9.5). Men had consistently higher AAMR than women throughout the study period (overall AAMR men: 45.51 (95% CI, 44.8-46.2); women: 12.5 (95% CI, 12.2-12.8). Both the groups had a similar increasing trend in AAMR, with men having a steeper increase. [AAPC men: 9.3% (95% CI, 8.5-10.8) versus AAPC women: 8.6%, 95% CI, 8.1-9.7]. Non Hispanic (NH) White population had the greatest AAMR throughout the study period, followed by NH Black and Hispanic or Latino. The NH White population had the largest increase in AAMR from 1999 to 2021 (AAPC 9.4%, 95% CI:8.9-10.1). Conclusion: In the United States, there has been a general increase in IHD mortality related to sleep apnea over the last two decades. This rising trend as noted in our analysis is concerning and underscores the need for more robust cardiovascular surveillance in these patients.

Abstract 4133488: Persistent Disparities in Chronic Ischemic Heart Disease-Related Mortality across Age, Sex, Race/Ethnicity in the United States, 1999 - 2020

Background: Chronic Ischemic Heart Disease (CIHD) is a heterogeneous group of cardiac diseases that cause significant morbidity and mortality. Previous studies demonstrated a decline in CIHD mortality rate (MR) but there is paucity of data on contemporary trends across different demographics in the United States (US). We examined the national trends in age-adjusted CIHD-MR (overall and stratified by demographics) in the US from 1999 to 2020. Methods: We retrospectively analyzed national death certificate data from the CDC WONDER database from 1999 to 2020. The underlying cause of death from CIHD was identified with ICD-10 code I25 in adults aged ≥35 years and the age-adjusted mortality rate was calculated per 100,000 population. We categorized race/ethnicity as Non-Hispanic White (NHW), Non-Hispanic Black (NHB), Latino or Hispanic, and other non-Hispanic groups. Trends in age-adjusted CIHD-MR (AAMR) were analyzed by age, gender, race/ethnicity, and geographic region were evaluated with Joinpoint regression, and expressed as an average annual percentage change (AAPC) with a 95% confidence interval. For sensitivity analysis, we repeated the study with data from death certificates that had CIHD as a contributing cause of death. Results: Out of 3.55 billion people aged ≥ 35 years, 5,985,088 died of CIHD (AAMR: 158.2 per 100, 000) [53.9% male, 81.6% NHW, 38.8% ≥85 years]. The AAMR was highest in males, the Northeast region, and NHB (Table 1). The AAMR was highest in those aged ≥85 years and was directly related to age (35-44 years: 8.3 per 100,000; ≥85 years: 1,943 per 100,000). The CIHD AAMR declined significantly overall in males, all races/ethnicities, and geographical areas (Table 1). Reanalysis (Sensitivity analysis) with any mention of CIHD as a contributing cause of death showed similar trends. Conclusion: Over the 22 years, CIHD-related mortality in the US has declined overall and for almost all demographic groups. However, there are age, gender, and racial disparities in the CIHD AAMR. These findings highlight the need for further longitudinal studies to understand the drivers of these disparities and for focused public health interventions to improve CIHD mortality outcomes in these populations.

Abstract 4134912: Geographic, Gender,&amp;Racial Trends in Mortality Due to Coronary Artery Disease in Diabetes among Adults Aged 25 and Older in the United States, 1999-2020: A CDC WONDER Database Analysis

Background: Coronary artery disease (CAD) is a significant contributor to mortality among adults with diabetes mellitus (DM) in the United States. This study examines the patterns of CAD-related mortality in individuals aged 25 and above with DM, with a particular focus on geographic, gender, and racial/ethnic discrepancies from 1999 to 2020. Methods: The study analyzed death certificate information from the CDC WONDER database from 1999 to 2020. Age-adjusted mortality rates (AAMRs), annual percent change (APC), and average annual percentage change (AAPC) were computed per 100,000 individuals, categorized by year, gender, race/ethnicity, and geographic areas. Results: Between 1999 and 2020, CAD in individuals with DM resulted in 1,462,279 deaths among adults aged 25 and above in the United States. The majority of these deaths occurred in medical facilities (44.2%) and at home (29.3%). The overall age-AAMR for CAD in DM-related deaths decreased from 36.3 in 1999 to 31.7 in 2020, with an AAPC of -0.96 (95% CI: -1.29 to -0.77 p &lt; 0.000001). Men had higher AAMRs (41.6) compared to women (22.6), with a more significant decrease in women (AAPC: -2.10, p &lt; 0.000001) than in men (AAPC: -0.34, p = 0.001200). Racial/ethnic disparities showed the highest AAMRs in American Indians/Alaska Natives (43.6), followed by Blacks (37.8), Hispanics (33.8), Whites (29.7), and Asians/Pacific Islanders (22.5). The most significant decrease was in Hispanics (AAPC: -1.64, p &lt; 0.000001). Geographically, AAMRs ranged from 13.7 in Nevada to 51.3 in West Virginia, with the highest mortality observed in the Midwest (AAMR: 34.5). Nonmetropolitan areas exhibited higher AAMRs (35.2) than metropolitan areas (29.7), with a more pronounced decrease in urban areas (AAPC: -1.22, p &lt; 0.000001) compared to nonmetropolitan areas (AAPC: -0.03, p = 0.854629). Conclusion: The decrease in AAMRs for CAD among individuals with DM from 1999 to 2020 indicates improvements in healthcare management. However, the ongoing disparities based on race, gender, and geography call for targeted public health interventions to guarantee fair access to cardiovascular care. Additional endeavors are necessary to comprehend and alleviate the root causes of these inequalities.

Abstract 4134768: Geographic, Gender,&amp;Racial Trends in Mortality Due to Heart Failure in Coronary Artery Disease Among Adults Aged 65 and Older in the United States, 1999-2020: A CDC WONDER Database Analysis

Backgrounds: Heart failure (HF) associated with coronary artery disease (CAD) is a significant contributor to mortality in the elderly population of the United States. This study examines trends in HF in CAD-related mortality among adults aged 65 and older, focusing on geographic, gender, and racial/ethnic disparities from 1999 to 2020. Methods: A retrospective analysis was performed using the CDC WONDER database death certificates from 1999 to 2020. Age-adjusted mortality rates (AAMRs), annual percent change (APC), and average annual percentage change (AAPC) were calculated per 100,000 persons, stratified by year, sex, race/ethnicity, and geographical region. Results: Between 1999 and 2020, there were 6,571,263 deaths attributed to coronary artery disease (CAD) and 6,135,540 deaths related to Heart Failure (HF) in the US. Among adults aged 65 and older, HF in CAD caused 1,597,451 deaths, with 37.1% occurring in medical facilities and 30.3% in nursing homes. The AAMRs for HF in CAD decreased from 241.7 in 1999 to 156.2 in 2020 (AAPC: -2.23, p &lt; 0.000001). This reduction was significant from 1999 to 2014, followed by a slight increase from 2014 to 2020. Men consistently had higher AAMRs than women (227.4 vs. 137.1), with women experiencing a more significant decline in rates (AAPC: -3.23, p &lt; 0.000001). Racial disparities revealed the highest AAMRs among Whites (183.0), followed by American Indians/Alaska Natives (153.7), Blacks (134.6), Hispanics (123.7), and Asians/Pacific Islanders (81.6). The most significant reductions were observed in Hispanics (AAPC: -2.68, p &lt; 0.000001). Geographically, AAMRs varied, ranging from 92.1 in Hawaii to 257.3 in West Virginia, with the Midwest showing the highest mortality (191.0). Nonmetropolitan areas exhibited higher AAMRs than metropolitan areas (202.6 vs. 166.1), although both showed moderate declines over time, more pronounced in urban areas (AAPC: -2.41, p &lt; 0.000001). Conclusion: The study uncovers notable variances in HF in CAD-related mortality among elderly individuals in the United States based on race, gender, and geographic location. While the decrease in AAMRs from 1999 to 2014 indicates progress in cardiovascular care, the subsequent rise from 2014 to 2020 and enduring disparities call for specific public health measures to tackle these inequalities.

Abstract 4134851: Demographic and regional disparities in cerebrovascular disease mortality among adult patients with pre-existing atherosclerosis in the United States from 1999-2020

Introduction: Atherosclerosis (ATH) is a major risk factor for cerebrovascular disease (CEVD), with persistent mortality disparities. Our study aims to identify vulnerable regions and demographics in the US adult population with pre-existing ATH at risk of CEVD. Methods: CDC Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) was used to access National Vital Statistics System data from 1999 to 2020. ATH-related CEVD was identified using CEVD as the underlying cause of death and ATH as a contributing cause of death. Results were presented as age-adjusted mortality rates (AAMR) per 100,000 population. Joinpoint regression was used to examine changes in trend and annual percentage change (APC). Results: A total of 325,408 CEVD occurred in patients with ATH from 1999 to 2020 (AAMR = 6.9, 95% CI: 6.8-7). Increased mortality rates were observed in males (AAMR = 6.3) as compared to females (AAMR = 5.1) (Figure, Panel A). AAMRs were highest in Non-Hispanic Whites [NHW] (5.7, 95% CI: 5.7 - 5.8), followed by non-Hispanic blacks [NHB] (5.5, 95% CI: 5.4 - 5.5), Hispanics (4.1, 95% CI: 4.0 - 4.1) and non-Hispanic American Indian/Alaska Native [NH-AIAN] (3.6, 95% CI: 3.4 - 3.8). Non-Hispanic Asian/Pacific Islander [NH-API] had the lowest mortality rates (3.4, 95% CI: 3.4 - 3.5). Region-wise analysis revealed that mortality rates were highest in the West (6.4, 95% CI: 6.3-6.4) and Midwest (6.2, 95% CI: 6.1-6.2). The South reported the rate of 5.5 (95% CI: 5.5-5.6), while the Northeast had the lowest rate (4.4, 95% CI: 4.3-4.4). Mortality rates were consistently higher in rural areas (6.1, 95% CI: 6.0-6.1) compared to urban areas (5.3, 95% CI: 5.3-5.4) throughout the study period. Overall AAMR rose from 9.0 in 1999 to 10.4 in 2001, then steadily declined before increasing to 3.6 from 2016 to 2020 (APC: 0.41). After an initial decline, AAMR increased in men (APC: 1.09) from 2016 and in women (APC: 5.09) from 2018. AAMR also increased among NH-API (APC: 8.9) and NHB (APC: 8.3) from 2018 onwards, and NHW (APC: 0.1) from 2016 (Figure, Panel B). Conclusions: Our study reveals significant mortality disparities from CEVD in patients with ATH, identifying males, NHW, and residents in the West and Midwest as particularly at increased risk. Rural areas consistently show higher mortality rates than urban areas. These findings highlight the need for targeted interventions and strategic provision of healthcare resources to improve outcomes for vulnerable populations.

Gallbladder cancer incidence and mortality rate trends in China: analysis of data from the population-based cancer registry.

Gallbladder cancer is a major health concern in China, and awareness of the associated incidence and mortality rates is particularly important given the aging population. To determine trends in gallbladder cancer incidence and mortality rates over 12years and quantitatively analyze the influence of demographic factors on these rates in China. We performed a retrospective study of 98,860 Chinese citizens using the Chinese Cancer Registry, a national database. Gallbladder cancer incidence and mortality data pertaining to patients treated between 2005 and 2017 were collected. Joinpoint regression models were used to estimate the annual percentage change (APC) and average APC (AAPC). We used age-period-cohort analyses and decomposition methods to investigate differing trends in incidence and mortality. The age-standardized gallbladder cancer incidence and mortality rates in China trended downward between 2005 and 2017, with AAPCs of -2.023% and -1.603%, respectively. Coefficients of age effect for incidence rate increased with age up to 70years and peaked at 70-79years, while coefficients of age effect for the mortality rate showed a consistent increase with age. Both coefficients of period for incidence and mortality rates increased in more recent periods; in terms of the cohort effect, coefficients of cohort for rates generally decreased in later birth years but showed a partial rise between 1982 and 1996. The crude incidence rates of gallbladder cancer according to demographic and non-demographic factors were 626.09% and -526.09% respectively (366.23% and -266.23% among men, and 6068.93% and -5968.93% among women, respectively). The rates were 543.01% and -443.01%, respectively, in urban areas and were 68.22% and 31.78%, respectively, in rural areas. The mortality rates according to demographic and non-demographic factors were -495.93% and 595.93%, respectively (-1763.10% and -1863.10% for men and -270.56% and -370.56% for women, respectively). These rates were -930.33% and 1030.33%, respectively, in urban areas and were 101.48% and -1.48%, respectively, in rural areas. The overall standardized gallbladder cancer incidence and mortality rates in China are trending downward, but not sufficiently so. Proper living and eating habits should be encouraged while exploring the establishment of long-term, standardized gallbladder cancer screening programs.
