Data and Statistics
Inflammatory Bowel Disease Prevalence (IBD) in the United States
Some people were more likely to report having IBD, including those:
- Aged 45 years or older.
- Hispanic or non-Hispanic white.
- With less than a high school level of education.
- Not currently employed.
- Born in the United States (compared with adults born outside of the United States).
- Living in poverty.
- Living in suburban areas.
This estimate does not include children younger than18 years, who may also have IBD. Most people with IBD are diagnosed in their 20s and 30s.
On the basis of the National Inpatient Sample data, there was no significant change in the hospitalization rate when Crohn’s disease was the primary diagnosis from 2003 to 2013. The hospitalization rate, however, increased significantly during this period from 44.2 to 59.7 per 100,000 population when it was listed as any secondary diagnosis.3
Compared with adults without IBD, those with IBD are more likely to have certain chronic health conditions that include:
- Cardiovascular disease (CVD).
- Respiratory disease.
- Kidney disease.
- Liver disease.4
In addition, clinicians should be aware of potential health-risk behaviors that are more prevalent among adults with IBD than those without, such as:
- Not getting enough sleep.
- Not meeting aerobic nor muscle-strengthening physical activity guidelines.4
