e16076 Background: Gastric cancer is the fourth leading cause of global cancer deaths. Despite declining incidence and mortality, it remains a significant contributor to the global disease burden. This study analyzes regional gastric cancer DALYs and mortality trends from 1990-2021 using the GBD database. Methods: The regional DALYs and mortality rates per 100,000 individuals aged 70+ from GBD 2021 were analyzed, with trends from 1990 to 2021 evaluated using AAPC, and statistical significance assessed by p-values. Results: In 2021, the greatest Age-standardized DALYs rates were recorded in Andean Latin America, with 3068.04 per 100,000; the lowest was found in High-income North America with 386.08 per 100,000. The most significant increase of DALYs rate from 1990 to 2021 was in Southern Sub-Saharan Africa, (AAPC = -0.3068%; 95% CI: -0.3852 to -0.2234; p < 0.000001), while in Western Europe, the largest decline was noted (AAPC = -2.9999%; 95% CI: -3.0164 to -2.9841; p < 0.000001). Andean Latin America was the region with the highest Age-standardized mortality rates (ASMRs) in 2021, at 207.58 per 100,000 while High-income North America had the lowest at 27.18 per 100,000. In Western Sub-Saharan Africa, the ASMRs were rising with an AAPC of -0.2601% (95% CI: -0.2872 to -0.2368; p < 0.000001), while Western Europe had the highest decline with an AAPC of -2.7658% (95% CI: -2.7895 to -2.7471; p < 0.000001). Conclusions: The global burden of diseases from 1990 to 2021 is regional in nature. In 2021, DALYs and mortality were predominantly high in Andean Latin America and East Asia and notably low in High-income North America. DALYs have risen across Southern Sub-Saharan Africa over three decades, and mortality increased over Western Sub-Saharan Africa, while both declined sharply in Western Europe. These trends underscore the importance of regionalized health solutions. DALY per 100,000.

e16237 Background: Alcohol use (AU) and Liver cell carcinoma (LCC) are significant contributors to adult mortality worldwide. Examining trends and disparities in AU and LCC-related deaths is essential for understanding public health challenges and formulating targeted interventions. This study investigates national mortality patterns related to AU and LCC in the United States from 1999 to 2023, emphasizing demographic, geographic, and temporal disparities. Methods: This descriptive analysis used the CDC WONDER database (1999–2023) to identify AU-related deaths (ICD-10 codes E24.4, F10, G32.2, G62.1, G72.1, I42.6, K70, K85.2, K86.0, R78.0, T51, X65, Y15) and LCC (ICD-10 code C22.0) in adults aged 25 and older. Age-adjusted mortality rates (AAMRs) per 1,000,000 individuals were calculated, stratified by gender, race/ethnicity, census region, urban-rural classification, and state. Trends were analyzed using Joinpoint regression to compute annual percent changes (APCs) and 95% confidence intervals (CIs). Statistical significance was set at p < 0.05, and analyses adhered to STROBE guidelines. Results: From 1999 to 2023, a total of 21,007 deaths were attributed to LCC and AU (Men: 18,836 Women: 2,171). AAMRs showed a stable trend from 1999 to 2003 (APC: 0.0; 95% CI: -8.7 to 4.9) but increased significantly from 2003 to 2019 (APC: 6.1; 95% CI: 5.7 to 7.4), stabilizing from 2019 to 2023 (APC: -0.6; 95% CI: -3.2 to 1.3). Men's AAMRs decreased from 1999 to 2003 (APC: -1.1; 95% CI: -10.4 to 3.4), then rose sharply from 2003 to 2019 (APC: 6.1; 95% CI: 5.6 to 7.1). For women, AAMRs increased significantly, particularly between 2013 and 2017 (APC: 12.4; 95% CI: -9.5 to 25.1). Non-Hispanic Black and White populations experienced notable increases in AAMRs, while Hispanic people showed an initial decline followed by an increase post-2004 (APC: 4.7; 95% CI: 3.7 to 7.9). The West had the highest regional AAMR (5.3; 95% CI: 5.2 to 5.5), while the Northeast recorded the lowest (2.1; 95% CI: 2.0 to 2.2). New Mexico had the highest state AAMR (8.4; 95% CI: 7.4 to 9.4), and Mississippi the lowest (1.2; 95% CI: 0.9 to 1.5). AAMRs rose more sharply in non-metropolitan areas from 1999-2020 (APC: 6.6; 95% CI: 5.9 to 7.8) compared to metropolitan regions from 2004 to 2020 (APC: 5.4; 95% CI: 4.9 to 6.5). Conclusions: AU and LCC-related mortality rates have increased significantly since 2003, with distinct gender, racial, and geographic disparities. Men and rural populations faced higher mortality increases, with notable variations across states and regions. These findings underscore the need for focused public health efforts to mitigate these disparities and address the growing burden of LCC and AU-related mortality.
