BACKGROUND: The epidemiology of inflammatory bowel disease (IBD) is poorly characterized in minorities in the U.S. We sought to enumerate the burden of IBD among racial and ethnic groups using national-level data.
METHODS: Data from the National Health Interview Survey was used to calculate prevalence and incidence of IBD among adults (≥ 18 years) in 1999. The Nationwide Inpatient Sample was queried to ascertain rates of IBD-related hospitalizations and the Underlying Cause of Death Database was accessed to quantify IBD-related mortality.
RESULTS: An estimated 1,810,773 adult Americans were affected by IBD yielding a prevalence of 908/100,000, which was higher in Non-Hispanic Whites (1099/100,000) compared with Non-Hispanic Blacks (324/100,000), Hispanics (383/100,000), and non-Hispanic Other (314/100,000). Relative to Non-Hispanic Whites, the odds ratios for having a diagnosis of IBD associated with being Non-Hispanic Black, Hispanic, and Other Non-Hispanic race after adjusting for age, sex, and geographic region were 0.33 (95% CI: 0.19 - 0.57), 0.45 (95% CI: 0.26 - 0.77), and 0.34 (95% CI: 0.12 - 0.93), respectively. IBD incidence was similarly lower in Non-Hispanic Blacks (24.9/100,000) and Hispanics (9.9/100,000) compared to Non-Hispanic Whites (70.2/100,000). The ratio of IBD hospitalizations to prevalence was disproportionately higher among Non-Hispanic Blacks (7.3%) compared with Non-Hispanic Whites (3.0%) and Hispanics (2.7%). Similarly, the ratio of IBD-related mortality was greater in Non-Hispanic Blacks (0.061%) compared to Non-Hispanic Whites (0.036%) and Hispanics (0.026%).
CONCLUSIONS: IBD disease burden is lower in ethnic minorities compared to Non-Hispanic Whites. However, IBD-related hospitalizations and deaths seem disproportionately high in Non-Hispanic Blacks.
