Viral hepatitis (VH) remains a leading cause of preventable mortality in the United States (US). Despite advancements in antiviral therapies, disparities in VH-related mortality persist across demographic, racial, and geographic groups. This study analyzes trends in VH-related mortality among US adults between 1999 and 2020 to identify high-risk subgroups and inform public health interventions. This retrospective cohort study analyzed VH-related deaths among US adults (≥25 years). Data were obtained from the CDC WONDER database, with cases identified using the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes B15–B19. Age-adjusted mortality rates (AAMRs) were calculated per 1,00,000 individuals and stratified by age, gender, race and geographical location. Temporal trends in mortality were analyzed by estimating annual percentage changes (APCs) in the AAMRs using the joinpoint regression model. A total of 3,59,035 VH-related deaths were recorded among US adults during 1999 to 2020 with a cumulative overall AAMR of 7.36 (95% CI: 7.33–7.38). Overall, the AAMRs increased significantly from 1999 to 2013 (APC: +3.21; P < .01), followed by a significant decline until 2020 (APC: −5.61; P < .01). Men exhibited higher AAMRs than women, with middle-aged adults (45–64 years) most affected compared to young (25–44 years) and older adults (65 to 85+ years). Non-Hispanic (NH) American Indians/Alaska experienced the highest AAMRs followed by NH Blacks/African Americans, Hispanics, NH Asians/Pacific Islanders and NH Whites populations. Geographically, mortality rates were higher in urban areas than in rural areas, in the Western region relative to other regions and in the District of Columbia compared to other states. Significant disparities in VH-related mortality persist across demographic and geographic subgroups, with particularly higher rates among men, NH American Indian/Alaska Native population, middle-aged adults, and residents of urban and Western US regions. Targeted public health strategies are essential to address these inequities and improve outcomes.

e16419 Background: Pancreatic cancer remains one of the most lethal malignancies worldwide. While high-income regions have long faced higher rates, recent trends show that lower-income regions are also beginning to see an increase. This study explores how pancreatic cancer incidence and prevalence have changed over the past 30 years among adults aged 70 and older assessing regional differences. Methods: We analyzed data from the Global Burden of Disease (GBD) spanning three decades (1990–2021) to assess pancreatic cancer incidence and prevalence rates among adults aged 70+. Data focused on different regions worldwide, grouping them by income levels using the Socio-demographic Index (SDI) and annual changes in incidence and prevalence rates were calculated. Results: In 2021, High-income Asia Pacific had the highest incidence rate at 119.52 per 100,000, whereas Low SDI regions had the lowest at 12.01 per 100,000. High-income regions accounted for the majority of cases, with over 140,000 reported, compared to fewer than 3,000 in the lowest-income areas. Andean Latin America experienced significant APC fluctuations, with a sharp rise from 2015 to 2019 followed by a decline, while High-income North America saw a recent decrease in incidence. Overall, most regions exhibit a steady increase in pancreatic cancer prevalence, with higher AAPCs in Sub-Saharan Africa, North Africa, and parts of Asia, while high-income regions show more moderate increases. Trend analysis reveals significant trends in pancreatic cancer incidence and prevalence among individuals aged 70+. Western Sub-Saharan Africa has the highest Average Annual Percent Change (AAPC) at 2.3248%, indicating the most substantial increase in prevalence from 1990 to 2021, followed by North Africa and the Middle East at 1.9906%. Low-middle SDI regions also show a steady rise with an AAPC of 1.718%, while high-income regions like High-income Asia Pacific report a notable AAPC of 1.595%. Conclusions: Our findings show a concerning rise in pancreatic cancer among older adults, with the most dramatic increases in regions like Western Sub-Saharan Africa and North Africa. To tackle this growing challenge, we need focused efforts on prevention, early detection, and accessible care, especially in lower-resource settings. Incidence percent changes.
