This study examined potential facilitators and barriers to pre-exposure prophylaxis (PrEP) use and their association with PrEP acceptability and motivations for adherence among 184 MSM and transgender women living in New York City. Participants were presented with educational information about PrEP and completed a computerized survey. Overall, 55.4% of(More)
OBJECTIVE We conducted a mixed-methods study to examine serodiscordant and seroconcordant (HIV-positive/HIV-positive) male couples' PrEP awareness, concerns regarding health care providers offering PrEP to the community, and correlates of PrEP uptake by the HIV-negative member of the couple. DESIGN Qualitative sub-study included one-on-one interviews to(More)
BACKGROUND In the USA, men who have sex with men (MSM) in primary partnerships are at elevated risk for human immunodeficiency virus (HIV) infection. Pre-exposure prophylaxis (PrEP), a new biomedical prevention strategy, has potential to reduce HIV transmission. This study examined predictors of PrEP adoption intentions among HIV-negative MSM in primary(More)
OBJECTIVES We used nationally representative data to investigate health disparities associated with sexual minority status among adults in the United States. METHODS We analyzed data from 11,114 adults who participated in the 2001 to 2010 waves of the National Health and Nutrition Examination Survey. Using multiple logistic regressions, we examined the(More)
Unprotected anal intercourse (UAI) remains a main risk factor for HIV among men who have sex with men (MSM) and this is of particular concern for partners of HIV serodiscordant status. However, HIV transmission risk has been demonstrated to vary by the sexual position adopted among partners. Guided by interdependence theory, this study examined how(More)
This study investigated and applied a compensatory model of risk and resilience to differences in past-year nonsuicidal self-injury (NSSI) and suicide attempts by sexual orientation using representative data from the 2007 Massachusetts Youth Risk Behavior Survey (n = 3,131). Self-identified lesbian, gay, bisexual, and questioning (LGBQ) adolescents(More)
Given the popularity of social media among young men who have sex with men (YMSM), and in light of YMSM’s elevated and increasing HIV rates, we tested the feasibility, acceptability and preliminary efficacy of a live chat intervention delivered on Facebook in reducing condomless anal sex and substance use within a group of high risk YMSM in a pre-post(More)
Age-discordant and earlier sexual debut are risk factors for HIV among men who have sex with men (MSM). Despite differences in the sociopolitical landscape over time, there are no studies sampling participants from the United States that have examined the role of birth cohort in relations between sexual debut characteristics and sexual risk among MSM. We(More)
Couples' adopting a relational orientation, when partners regard themselves as a collective unit, is associated with optimal health. HIV-positive men and their HIV-negative partners (N = 116 serodiscordant male couples) were surveyed. Logistic regression showed greater relational orientations of HIV-positive [adjusted odds ratio (aOR) = 7.87; 95% confidence(More)
BACKGROUND Substance use is strongly linked to HIV risk, and members of couples can have a powerful influence on each other's health behaviors. We examined whether couple-level patterns of stimulant use were differentially associated with engaging in condomless anal intercourse with primary partners and outside partners. METHODS Members of HIV(More)
