EVOLVING LANDSCAPE OF INFLAMMATORY BOWEL DISEASE IN G20 NATIONS (1990-2019): A COMPREHENSIVE GLOBAL ASSESSMENT

Abstract

Abstract BACKGROUND As pivotal players in the global economy, the G20 countries not only lead in economic dynamics but also in health challenges. Recent data reveals an escalating burden of Inflammatory Bowel Disease (IBD) in these nations. Understanding this trend is crucial to frame healthcare strategies and ensure the well-being of a significant portion of the global population. METHOD We employed data on IBD prevalence, incidence, mortality, and DALYs for G20 countries from the Global Burden of Disease (GBD) 2019 study. Using standardized statistical techniques, we analyzed by age, sex, year and location across G20 countries, estimating incidence and prevalence with the DisMod-MR 2.1 tool and mortality through the Cause of Death Ensemble Model (CODEm). RESULTS From 1990 to 2019, IBD prevalence figures in the G20 nations escalated from 2,999,730 (95%UI: 2,625,581-3,416,963) to 4,254,467 (3,809,445-4,751,041), marking a 42% (38-46) surge in the Annual Percentage Change (APC). Meanwhile, the incidence rose by 30% (26-35), mortality by 72% (49-97), and DALYs by 27% (15-43). Among these nations, China witnessed a striking 314% increase in incidence, closely followed by South Korea at 288%. Death rates were most pronounced in European Union members, with Portugal at the helm (441%), trailed by Italy (433%) and Germany (418%). Germany also led in DALYs growth with a 289% APC. Examining Age-standardized mortality rates, Germany again topped the list with a 244% increase, shadowed by Italy (186%) and the United States (147%). Over the past three decades, older populations demonstrated a rising IBD burden. In gender comparisons, males experienced a more significant incidence increase (32% vs. females at 28%) and DALYs (30% vs. females at 24%). Conversely, females had a steeper death rate growth, 77% as opposed to males at 67%. CONCLUSION In 2019, IBD was responsible for 2.02% of digestive disease-related deaths and 2.30% of associated disabilities in the G20 nations. The stark rise in IBD prevalence, especially in countries like China, South Korea, and European Union members, emphasizes a pressing need for targeted clinical approaches and proactive health policies to mitigate this escalating burden.
