(HealthDay News) – Compared to whites, Hispanic and black patients have an increased prevalence of adenomas and an increased risk of advanced adenomas, according to a study published in the June issue of Alimentary Pharmacology & Therapeutics.
In an effort to determine the prevalence of adenomas among whites, blacks, and Hispanics, Benjamin Lebwohl, MD, of the Columbia University Medical Center in New York City, and colleagues reviewed data from the electronic medical records of 5,075 patients aged 50 years or older undergoing first-time colonoscopy since 2006.
The researchers found that at least one adenoma was detected in 19% of 3,542 whites, 22% of 942 Hispanics, and 26% of 591 blacks (Hispanics versus whites P=0.09; blacks versus whites P=0.0001). A higher rate of adenomas was seen in Hispanics and blacks vs. whites (relative risk, 1.37 and 1.76, respectively). There was also an increased risk of advanced adenomas in Hispanics and blacks vs. whites (odds ratioHispanics, 2.25; and odds ratioblacks, 1.91)
“Adenoma prevalence was higher in blacks and Hispanics than that in whites,” the authors write. “Both groups were at greater risk of having proximal adenomas in the absence of any distal pathology than whites, where these lesions would have only been detected by colonoscopy.”
