Study Looks at Male Circumcision as HIV Prevention Among Black Men in Baltimore

HIV risk appears to be lower among U.S. black men who have been circumcised and are considered at high risk of contracting the virus than among black men who have not been circumcised, according to a study published on Wednesday in the Journal of Infectious Diseases, Reuters reports. Two other studies in the journal also examine the benefits of male circumcision to prevent the spread of disease and infection.

For one of the studies, CDC researcher Lee Warner and colleagues looked at black men living in Baltimore and found that 10% of those who were at high risk of HIV and were circumcised had the virus, compared with 22% of those who were not circumcised. According to the report, "Circumcision was associated with substantially reduced HIV risk in patients with known HIV exposure, suggesting that results of other studies demonstrating reduced HIV risk for circumcision among heterosexual men likely can be generalized to the U.S. context."

Ronald Gray of Johns Hopkins University and colleagues in an editorial accompanying the study noted that in the U.S., circumcision is less common among blacks and Hispanics. However, blacks and Hispanics are the most at-risk of groups for contracting the virus. "Thus, circumcision may afford an additional means of protection from HIV in these at-risk minorities," they wrote.
