Inflammatory bowel disease (IBD) takes a greater toll on US adults than previously believed, according to recent research that also reported how the illness affects people of various educational levels, job status, and racial or ethnic backgrounds.
Researchers from the CDC used the 2015 National Health Interview Survey to drill deeper than earlier studies, which were based on claims data or geographically limited data. Their analysis showed that IBD, the umbrella term for Crohn disease and ulcerative colitis, affects 3.1 million or 1.3% of US adults—nearly 3 times more than in previous estimates.
