ABSTRACT
BACKGROUND: An increasing incidence of pediatric-onset inflammatory bowel disease (PIBD) has been reported in many countries. However, the global burden and distribution of this disease remain less understood. We aimed to examine the global epidemiology and trends of PIBD from 1990 to 2019.
METHODS: Data from the 2019 Global Burden of Disease Study, covering 204 countries, were analyzed. We assessed key measures like incidence, prevalence, mortality, and disability-adjusted life years (DALYs) using linear regression to calculate annual percentage changes and assess trends.
RESULTS: Between 1990 and 2019, the PIBD incidence rate increased and the DALY rate and mortality rate declined. The incidence rate was notably elevated in the high Socio-demographic Index (SDI) quintile, reaching 6.3 per 100 000 person-years, corresponding to 13 914 new cases in 2019. Incidence and prevalence of PIBD positively correlated with the SDI, while higher death and DALY burdens were observed in lower-SDI countries. In 2019, the top 5 countries with the highest PIBD incidence rates were Canada (19.9 per 100 000 population), Denmark (12.4 per 100 000 population), Hungary (8.5 per 100 000 population), Austria (8.1 per 100 000 population), and the United States (7.4 per 100 000 population). Several countries experienced significant increases in incidence rates from 1990 to 2019, led by Taiwan (annual percent change 4.2%), followed by China (2.8%), Japan (2.1%), Australia (1.8%), and Hungary (1.6%).
DISCUSSION: PIBD incidence has significantly increased since 1990. High-SDI countries face higher incidence, while lower-SDI countries experience higher mortality and DALY burdens. The study underscores the need for ongoing monitoring and research to address this emerging public health issue.
