Correlates of HIV Infection Among Transfemales, San Francisco, 2010
Objectives. We evaluated the use of respondent-driven sampling (RDS) among a high-risk population of transfemales. We also obtained up-to-date epidemiological data on HIV infection and related correlates among this population. Methods. We evaluated the utility of RDS in recruiting a sample of 314 transfemales in San Francisco, California, from August to December 2010 by examining patterns of recruitment and assessing network sizes and equilibrium…
Correlates of Unprotected Vaginal or Anal Intercourse with Women Among Substance-Using Men Who Have Sex with Men
Implementing Rapid HIV Testing With or Without Risk-Reduction Counseling in Drug Treatment Centers
Objectives. We examined the effectiveness of risk reduction counseling and the role of on-site HIV testing in drug treatment. Methods. Between January and May 2009, we randomized 1281 HIV-negative (or status unknown) adults who reported no past-year HIV testing to (1) referral for off-site HIV testing, (2) HIV risk-reduction counseling with on-site rapid HIV testing, or (3) verbal information about testing only with on-site rapid HIV testing. Res…
Depression is Associated with Sexual Risk Among Men Who Have Sex with Men, but is Mediated by Cognitive Escape and Self-Efficacy
Using Social Networks to Reach Black MSM for HIV Testing and Linkage to Care
Decreases in Community Viral Load Are Accompanied by Reductions in New HIV Infections in San Francisco
BACKGROUND: At the individual level, higher HIV viral load predicts sexual transmission risk. We evaluated San Francisco's community viral load (CVL) as a population level marker of HIV transmission risk. We hypothesized that the decrease in CVL in San Francisco from 2004-2008, corresponding with increased rates of HIV testing, antiretroviral therapy (ART) coverage and effectiveness, and population-level virologic suppression, would be associated…
Contingency management to reduce methamphetamine use and sexual risk among men who have sex with men
While it is possible to enroll and retain MSM who use methamphetamine in a trial of CM conducted outside drug treatment, our data suggest that CM is not likely to have a large, sustained effect on methamphetamine use
Racial/Ethnic Differences in Seroadaptive and Serodisclosure Behaviors Among Men Who Have Sex with Men
Affective Correlates of Stimulant Use and Adherence to Anti-retroviral Therapy Among HIV-positive Methamphetamine Users
The use of stimulants has important implications for HIV prevention and care. However, few investigations have examined psychological correlates of substance use and adherence to anti-retroviral therapy (ART) among HIV-positive stimulant users. This cross-sectional investigation examined affective correlates of stimulant use and ART adherence among HIV-positive methamphetamine users. In total, 122 HIV-positive men who have sex with men or transge…
Written Informed Consent and Hiv Testing Rates
Goldman et al. posit without empirical evidence that written informed consent is not a barrier to routine HIV testing.1 Our experience in San Francisco, California, suggests otherwise. In May 2006, the San Francisco Department of Public Health Medical Care System, which includes an acute care hospital, a long-term care facility, and more than 15 primary health care centers, eliminated the requirement for a separate written informed consent form f…
‘Barebacking’ in a diverse sample of men who have sex with men
OBJECTIVES: To assess the prevalence of and factors associated with "Barebacking" as a sociocultural phenomenon in a sample of HIV-positive and -negative men who have sex with men (MSM), and to assess the reasons for barebacking and venues for meeting partners. DESIGN: A cross-sectional survey of MSM recruited in the San Francisco Bay Area from July 2000 to February 2001. METHODS: Barebacking, defined as "intentional anal sex without a condom wit…
Drug Use and Sexual Risk Behavior Among Gay and Bisexual Men Who Attend Circuit Parties
CONTEXT: HIV risk behavior among urban gay/bisexual men has recently increased. High-risk sexual activity and drug use may be particularly high during circuit party (CP) weekends, during which gay/bisexual men congregate for social activities and dancing. OBJECTIVES: To compare prevalence of risk behaviors during CP weekends with those during non-CP weekends. DESIGN: Cross-sectional study. PARTICIPANTS: 295 gay/bisexual men from the San Francisco…
