Background:
To comprehensively analyze the global burden of inflammatory bowel disease (IBD) among women of reproductive age from 1990 to 2021 and make future projections to 2050.
Methods:
We utilized GBD2021 data to conduct a comprehensive analysis of IBD burden across five social-demographic index (SDI) regions, 21 GBD regions, and 204 countries. We assessed trends in IBD-related incidence, prevalence, mortality, and disability-adjusted life years (DALYs) and performed decomposition analysis to identify contributing factors. Additionally, we predicted the future trends of IBD burden from 2022 to 2050 using eight machine learning models.
Results:
From 1990 to 2021, global IBD burden among women of reproductive age showed a slight upward trend in incidence, prevalence, DALYs, and mortality. Population growth was the primary contributor to these increases. Significant regional disparities were observed, with high SDI regions continuing to bear the heaviest burden. While mortality rates declined in high SDI regions due to improved healthcare, low- and lower-middle SDI regions experienced higher mortality due to limited resources and access to diagnostic and treatment options. Age-specific trends revealed a higher burden in older age groups (40-49), while younger women (20-24) in low SDI regions exhibited higher mortality and disability.
Conclusion:
This study provides in-depth insights into the global burden of IBD among women of reproductive age, which can guide the formulation of targeted prevention and management strategies and rational resource allocation to address the challenges posed by IBD in the future.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
