In the United States, HIV disproportionately affects black residents. In the current study, the authors from the San Francisco Department of Public Health conducted a cross-sectional survey of men who have sex with men (MSM) in San Francisco through time-location-sampling, analyzing the dynamics of racial mixing and HIV risk. Through computer-assisted interviews, MSM were asked about their selection of sexual partners, partner preferences, HIV-risk perceptions and social mixing in terms of race/ethnicity.
Among 1,142 MSM, 56 percent were white; 22 percent Latino; 14 percent Asian; and 9 percent black. Altogether, participants reported 3,532 sexual partnerships in the previous six months.
Black MSM had a significant, three-fold higher level of same-race partnering than would be expected through chance alone; that is, in the absence of selective forces regarding race among partnerships. Among participants, black MSM were reported to be the least preferred as sexual partners; at a higher risk for HIV; counted less frequently among friends; considered hardest to meet; and perceived as less welcome by other MSM in San Francisco venues where MSM congregate.
