Blacks, Hispanics Have Increased Adenoma Prevalence

Higher rate of adenomas, increased risk of advanced adenomas for Hispanics, blacks versus whites

WEDNESDAY, May 16 (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, M.D., from 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 percent of 3,542 whites, 22 percent of 942 Hispanics, and 26 percent 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 versus whites (relative risk, 1.37 and 1.76, respectively). There was also an increased risk of advanced adenomas in Hispanics and blacks versus 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."
