In a study looking at social and sexual mixing between ethnic groups in men who have sex with men, researchers show that social barriers faced by black gay men may have a serious impact on their health and well-being.

In the US, there is a disproportionate burden of HIV infection in Black Americans, who accounted for nearly half of all HIV/AIDS cases diagnosed in 2006 – four times the national average.

A total of 1,142 gay men took part in computer-assisted interviews. They were asked about their own ethnicity, the race of their sexual partners in the last six months, their perception of how easy it is to meet sexual partners of different ethnicities, where they meet sexual partners, their view of HIV infection risk and the predominant race of their network of friends.

Black gay men are the least preferred of sexual partners by other races. Black men are perceived to be riskier to have sex with, which can lead to men of other races avoiding Black men as sexual partners. They are also perceived as less welcome in the common social venues of gay men in San Francisco. As a result, Black men are three times more likely to have sexual partners that are also Black, than would be expected by chance alone.

The authors conclude: “The racial disparity in HIV observed for more than a decade will not disappear until the challenges posed by a legacy of racism towards Blacks in the US are addressed.”
