METHODS We evaluated these correlates among 946 NTMSM from 6 US cities who participated in an internet-based survey in 2007. (More)
BACKGROUND Lack of human immunodeficiency virus (HIV) infection awareness may be a driver of racial disparities in HIV infection among men who have sex with men (MSM). Lack of awareness is typically measured by comparing HIV test result to self-reported HIV status. This measure may be subject to reporting bias and alternatives are needed. METHODS The(More)
BACKGROUND Various metrics for HIV burden and treatment success [e.g. HIV prevalence, community viral load (CVL), population viral load (PVL), percent of HIV-positive persons with undetectable viral load] have important public health limitations for understanding disparities. METHODS AND FINDINGS Using data from an ongoing HIV incidence cohort of black(More)
