BACKGROUND HIV incidence in the United States among men who have sex with men (MSM) has been increasing since 2000, and MSM remain the most heavily impacted risk group in the US HIV epidemic. METHODS We modeled HIV transmissions, using data from MSM in five US cities from the National HIV Behavioral Surveillance System, the HIVNET Vaccine Preparedness(More)
In collaboration with the Centers for Disease Control and Prevention, participating state and local health departments, universities, and community-based organizations applied venue-based, time-space sampling methods for the first wave of National HIV Behavioral Surveillance of men who have sex with men (NHBS-MSM). Conducted in 17 metropolitan areas in the(More)
PROBLEM/CONDITION For CDC's goal of reducing the number of new human immunodeficiency virus (HIV) infections to be achieved, data are needed to assess the prevalence of HIV-related risk behaviors at a given time, monitor trends in these behaviors, and assess the correlates of risk. These data also can be used to evaluate the extent to which current(More)
OBJECTIVES We measured HIV seroprevalence and associated risk factors among persons in New York City's house ball community. METHODS In 2004 we conducted a venue-based risk-behavior survey and HIV testing in the house ball community. RESULTS Of the 504 study participants, 67% were male, 14% female, and 18% transgender. Mean age was 24 years (range=15-52(More)
BACKGROUND The reasons for black/white disparities in HIV epidemics among men who have sex with men have puzzled researchers for decades. Understanding reasons for these disparities requires looking beyond individual-level behavioral risk to a more comprehensive framework. METHODS AND FINDINGS From July 2010-December 2012, 803 men (454 black, 349 white)(More)
BACKGROUND Correlates of main reasons for not HIV testing, HIV testing intentions, and potential use of an over-the-counter rapid HIV test (OTCRT) among men who have sex with men who have never tested for HIV (NTMSM) are unknown. METHODS We evaluated these correlates among 946 NTMSM from 6 US cities who participated in an internet-based survey in 2007. (More)
PURPOSE To describe factors associated with racial disparities in HIV (human immunodeficiency virus) incidence among men who have sex with men (MSM) in the United States. METHODS In a longitudinal cohort of black and white HIV-negative MSM in Atlanta, HIV incidence rates were compared by race. Incidence hazard ratios (HRs) between black and white MSM were(More)
BACKGROUND Internet-based sampling methods may reach men who have sex with men (MSM) who don't attend physical venues frequented by MSM and may be at higher risk of HIV infection. METHODS Multivariate logistic regression was used to examine characteristics of adult MSM participants in 2 studies conducted in the same 5 U.S. cities: the 2003-2005 National(More)
Reductions in human immunodeficiency virus (HIV) incidence with pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) will require significant coverage of those at risk. We propose a simplified framework, similar to the HIV care continuum, to achieve protection with PrEP as follows: 1. At-risk MSM; 2. Awareness of and willingness to take PrEP;(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)
