Disease burden for colorectal cancer varies considerably by ethnicity. US Hispanics have a high colorectal adenoma burden but a lower incidence of colon cancer compared to non-Hispanic whites (NHW). Although the incidence of IBD in US Hispanics is rising, data is lacking on the prevalence of IBD-associated dysplasia within Hispanics. The aims of this study were to examine 1) differences in prevalence of colon dysplasia between Hispanics and NHW 2) differences in risk factors for dysplasia between Hispanics and NHW.
