Introduction:
Inflammatory bowel disease (IBD) is a global health issue profoundly impacting quality of life. The United States accounts for nearly a quarter of the world's IBD patients, with the highest prevalence rates. This study aims to identify the demographic and regional trends of IBD-related mortality in the U.S. from 1999 to 2020.
Methodology:
Our study utilized the CDC Wonder database to gather mortality data for IBD (Crohn's disease and ulcerative colitis) from 1999 to 2020. Results were presented as age-adjusted mortality rates (AAMR) per 100,000 population, with Joinpoint regression used to analyze trend changes and calculate annual percentage change (APC).
Results:
A total of 62,310 IBD-related deaths were recorded. From 1999 to 2020, AAMR for Crohn's disease increased from 0.79 to 0.97, declining from 1999 to 2018 (APC: - 0.22) but surging from 2018 onwards (APC: 11.26). Women had a higher AAMR (0.81) compared to men (0.77). The highest rates were among non-Hispanic whites (0.86), followed by non-Hispanic blacks (0.48) and Hispanics (0.21). AAMR varied by state, ranging from 0.29 in Hawaii to 1.42 in Vermont. For ulcerative colitis, AAMR rose from 0.56 in 1999 to 0.63 in 2020, following a similar trend: a decline from 1999 to 2018 (APC: - 0.37) followed by an increase (APC: 12.21). State-specific AAMR ranged from 0.14 in Hawaii to 0.67 in Oregon.
Conclusion:
This study highlights a decrease in AAMR for both diseases from 1999 to 2018, followed by significant increases from 2018 to 2020, indicating a need for targeted interventions.

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...
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...

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...
