PURPOSE: Previous studies have suggested that inflammatory bowel disease (IBD) occurs at higher rates among non-Hispanic Whites (NHWs) compared to other ethnicities; however, Hispanics as the largest minority in the United States remain underrepresented in IBD research and we hypothesize that they have similar rates of IBD. We examined the epidemiology, demographics, clinical presentation, and treatment of IBD in a predominantly Hispanic cohort in Los Angeles (LA) County.
METHODS: This was a retrospective cohort study based at Olive View-UCLA Medical Center, one of the three major safety-net hospitals in LA County. Electronic medical records from 2015 to 2018 were queried, and biopsy-proven cases of IBD (n = 170) were identified. Outcomes included the incidence and prevalence of IBD, disease distribution, treatment, and IBD-related surgery.
RESULTS: The incidence of IBD among Hispanics was 175 (95% confidence interval [CI] 127-240) and 113 (95% CI 62-200) for NHWs per 100,000 person-years. Prevalence of IBD per 100,000 people was 418 (95% CI 341-512) for Hispanics and 557 (95% CI 431-739) for NHWs. Notably, the proportion of Hispanic IBD patients with a history of smoking was 21.5% vs 50.8% in NHWs (p = 0.011). There were no significant differences between the two groups with regard to Montreal classification, pharmacotherapy, or IBD-related surgery.
CONCLUSIONS: In one of the largest US studies of Hispanics with IBD, and the only one to have both clinical and histopathologic confirmation as inclusion criteria, we found the incidence and prevalence of IBD among Hispanics to be higher than previously recognized and comparable to NHWs. Additionally, Hispanic IBD patients had lower rates of smoking compared to NHWs.
