How do young black men having sex with only women differ from those also having sex with men?

In the US, young Black men (YBM) disproportionately acquire sexually transmissible infections (STI), including infection with HIV. This secondary analysis compared sexual behaviours of YBM (n = 568) not reporting sex with men with those of YBM who have sex with men (YBMSM). In the present study YBMSM were generally less likely to report engagement in sexual risk behaviours, less likely to report incarceration and more likely to ever be tested for HIV. The findings suggest that elevated rates of HIV and/or STI among YBMSM may be a product of higher prevalence rates in sexual networks.
