Global Burden of Inflammatory Bowel Disease Among Children and Adolescents: A Comprehensive Analysis (1990–2019)

Abstract

Objective: We summarize the global, regional, and national burden of inflammatory bowel disease (IBD) in children and adolescents from 1990 to 2019. Methods: Based on the Global Burden of Disease Study 2019, the data of IBD in children and adolescents were analyzed by sex, age, year, and location. Joinpoint analysis was applied to assess the temporal trend of the disease burden. Results: From 1990 to 2019, the incidence of IBD in children and adolescents increased by 22.8%, from 20,897.42 to 25,658.55 cases, especially in high SDI region. During the same period, the DALY numbers decreased by 53.5%, from 243,081.06 to 113,119.86, with all SDI regions experiencing a clear drop in DALYs except high SDI regions. In 2019, early-onset IBD incidence and DALY numbers were reported at 2,053.52 (95% UI: 1,575.62 to 2,677.49) and 73,797.46 (95% UI: 43,655.86 to 105,998.63), respectively. Conclusion: Early-onset IBD in children and adolescents remains a significant global health concern. The disease burden has not improved in developed countries over the past 30 years, highlighting the need for targeted interventions.
