ABSTRACT: Men who have sex with men and women (MSMW) represent an important target population for understanding the spread of HIV because of the inherent bridging aspect of their sexual behavior. Despite their potential to spread HIV between gender groups, relatively little recent data have been reported about this population as a subgroup distinct from men who have sex with men only. This paper analyzes data from the Chicago site of Sexual Acquisition and Transmission of HIV Cooperative Agreement Program to characterize 343 MSMW in terms of their demographics, drug use, sexual risk behavior, sexual identity, and sex partners. Results show the MSMW sample to be extremely disadvantaged; to have high rates of drug use, including injection and crack use; to report more female than male sex partners; to not differ from gay and heterosexual men in rates of condom use; and, for the most part, to report sexual identities that are consistent with their sex behavior. MSMW represent an important subpopulation in the HIV epidemic and should be targeted for risk reduction interventions.

ABSTRACT: We investigated the prevalence of HIV-positive patients discussing alcohol use with their HIV primary care providers and factors associated with these discussions.
We recruited 1225 adult participants from 10 HIV care clinics in three large US cities from May 2004 to 2005. Multivariate logistic regression analysis was used to assess the associations between self-reported rates of discussion of alcohol use with HIV primary care providers in the past 12 months and the CAGE screening measure of problem drinking and sociodemographic variables.
Thirty-five percent of participants reported discussion of alcohol use with their primary care providers. The odds of reporting discussion of alcohol were three times greater for problem drinkers than for non-drinkers, but only 52% of problem drinkers reported such a discussion in the prior 12 months. Sociodemographic factors associated with discussion of alcohol use (after controlling for problem drinking) were being younger than 40, male, being non-white Hispanic (compared with being Hispanic), being in poorer health, and having a better patient-provider relationship.
Efforts are needed to increase the focus on alcohol use in the HIV primary care setting, especially with problem drinkers. Interventions addressing provider training or brief interventions that address alcohol use by HIV-positive patients in the HIV primary care setting should be considered as possible approaches to address this issue.

ABSTRACT: As HIV/AIDS continues to disproportionately affect African American communities, there is a growing need for empirically based, culturally appropriate, tailored interventions for this clientele. As part of a Health Resources and Services Administration (HRSA)/Special Projects of National Significance (SPNS) initiative to increase prevention amongst those living with HIV, we implemented the Treatment Advocacy Program Intervention at Mount Sinai Hospital in Chicago, IL, USA. The main goal of the intervention was to help patients increase their medication adherence and sexual safety skills. This paper describes the rationale for implementing this peer-based HIV-prevention intervention, discusses how the intervention was tailored to work within our low socio-economic status, urban patient population, and reviews the training and quality assurance activities needed to integrate the intervention into our primary care clinic. We review the intervention content in detail, including the structure of the multiple, one-on-one education sessions, and the core topics covered (medication adherence and sexual safety). Finally, we discuss the challenges in implementing this program, many of which arise from the chaotic social situations that our patients experience.

ABSTRACT: Factors associated with HIV transmission risk may differ between subgroups of persons living with HIV/AIDS (PLWHA). This study examined such factors in a sample of PLWHA recruited in 3 US metropolitan areas. Sexually active participants were categorized as gay or bisexual men (GBM) (n = 545), heterosexual men (HSM, n = 223), or women (n = 214). Of 982 participants, 27.1% reported serodiscordant unprotected anal or vaginal sex (SDUAV). SDUAV was associated with multiple (2 or more) partners, using poppers, and lower safer sex self-efficacy among GBM. SDUAV was associated with multiple partners among HSM. Among women, factors examined were not associated with SDUAV. These findings are consistent with prior research and facilitate our ability to target those who may be most at risk for transmitting HIV among HIV-positive GBM. More research must be conducted to identify factors associated with risk behavior among HSM and women.

ABSTRACT: Men who have Sex with Men (MSM) who find partners on the Internet tend to be sexually risky. A "cognitive escape" perspective maintains that feeling overwhelmed by rigorous sexual norms may lead one to cognitively disengage from these demands as a coping strategy. We thus proposed that the Internet might facilitate less restrained behavior among men whose psychological characteristics make them vulnerable to "escape"-based risk. We tested this in a socio-economically and ethnically diverse cross sectional survey sample of MSM, n=817. Men who sought sex on-line reported more unprotected sex and sexually transmitted infections, controlling for demographics and overall number of sex partners. Consistent with an escape perspective, partner choice and sexual context, alcohol and drug use, and "burnout" or fatigue over sexual safety mediated the relationship between Internet use and sexual risk. The Internet is not an isolated source of risk; interventions must address the psychosocial aspects of this venue.

ABSTRACT: Understanding why people join HIV vaccine efficacy trials is critical for trial recruitment and education efforts. We assessed participants' motivations for joining the VaxGen VAX004 study, a randomized, double-blind, placebo-controlled, phase 3 multicenter trial. Of 5417 participants, 94% were men who have sex with men (MSM) and 6% were women at risk for heterosexual transmission of HIV. Most participants gave altruistic reasons for trial participation: 99% reported having joined to help find an HIV vaccine, and 98% reported having joined to help their community. Some gave more personal reasons: 56% joined to reduce risk behavior and 46% joined to get protection from HIV. Additional reasons related to receiving services or compensation included to obtain information about HIV (75%), to receive free HIV testing (34%), and for financial reimbursement (14%). Multivariate logistic regression analysis showed that female participants were significantly more motivated than male participants to join the trial for protection and to receive services or compensation (all P<0.05). Participants with 13 or more sex partners in the 6 months before enrollment were more likely than those with fewer sex partners to report having joined the trial for protection but less likely to have joined to reduce risk behavior (both P<0.05). Because many participants reported personal protection from HIV as their reason for joining, vaccine trial risk-reduction counseling should continue to emphasize the placebo-controlled trial design and unknown efficacy of the test product, particularly for women and persons with large numbers of sex partners. Because a significant minority of participants reported joining to receive HIV information, HIV testing, and financial reimbursement, a need is indicated for provision of HIV prevention services outside research trials and for monitoring to ensure that participants are not motivated to join trials for financial gain.

ABSTRACT: Men who have sex with men (MSM) continue to account for the largest number of new HIV infections in the United States, but limited data exist on independent risk factors for infection beyond the early 1990s. The HIV Network for Prevention Trials Vaccine Preparedness Study enrolled 3257 MSM in 6 US cities from 1995 to 1997. HIV seroincidence was 1.55 per 100 person-years (95% confidence interval: 1.23-1.95) over 18 months of follow-up. On multi-variable analysis using time-dependent covariates, independent risk factors for HIV seroconversion were increased number of reported HIV-negative male sex partners (adjusted odds ratio (AOR) = 1.14 per partner, population attributable risk (PAR) = 28%), nitrite inhalant use (AOR = 2.2, PAR = 28%), unprotected receptive anal sex with an HIV unknown serostatus partner (AOR = 2.7, PAR = 15%) or HIV-positive partner (AOR = 3.4, PAR = 12%), protected receptive anal sex with an HIV-positive partner (AOR = 2.2, PAR = 11%), lack of circumcision (AOR = 2.0, PAR = 10%), and receptive oral sex to ejaculation with an HIV-positive partner (AOR = 3.8, PAR = 7%). Having a large number of male sex partners, nitrite inhalant use, and engaging in receptive anal sex explained the majority of infections in this cohort and should be targeted in prevention strategies for MSM.

ABSTRACT: Prior reports associating substance use with sexual risk behavior have generally used summary measures and have not adjusted for participants' background levels of substance use. In this 1999-2001 US study (the EXPLORE study), the authors determined whether substance use during sex was independently associated with sexual risk during recent sexual episodes, as reported by 4,295 human immunodeficiency virus-negative men who have sex with men. The main outcome measure was serodiscordant unprotected anal sex (SDUA). The influence of participant-level characteristics was examined by using repeated-measures logistic models. In assessing the influence of episode-level predictors on SDUA, the influence of participant-level characteristics, including 6-month substance use, was removed by using conditional logistic regression, in effect making each participant his own control. The authors also adjusted for partner characteristics. Eleven percent of participants reported heavy alcohol use, 37% used poppers, 19% sniffed cocaine, and 13% used amphetamines. In the participant-level analysis, use of poppers, amphetamines, and sniffed cocaine as well as heavy alcohol use in the prior 6 months were independently associated with SDUA. In the conditional analysis, consumption of > or = 6 alcoholic drinks or use of poppers, amphetamines, or sniffed cocaine just before or during sex was independently associated with SDUA. The authors concluded that programs aimed at preventing human immunodeficiency virus transmission should emphasize the influence of substance use during sex on increased risk behavior.

ABSTRACT: We describe the prevalence of risk behaviors at baseline among men who have sex with men (MSM) who were enrolled in a randomized behavioral intervention trial conducted in 6 US cities.
Data analyses involved MSM who were negative for HIV antibodies and who reported having engaged in anal sex with 1 or more partners in the previous year.
Among 4295 men, 48.0% and 54.9%, respectively, reported unprotected receptive and insertive anal sex in the previous 6 months. Unprotected sex was significantly more likely with 1 primary partner or multiple partners than with 1 nonprimary partner. Drug and alcohol use were significantly associated with unprotected anal sex.
Our findings support the continued need for effective intervention strategies for MSM that address relationship status, serostatus of partners, and drug and alcohol use.

ABSTRACT: We describe the intervention tested in EXPLORE, an HIV prevention trial aimed at men who have sex with men (MSM), and test the empirical basis of the individually tailored intervention.
Data on participants' self-efficacy, communication skills, social norms, and enjoyment of unprotected anal intercourse were examined in relation to sexual risk. Combinations of these factors, together with alcohol use and noninjection drug use, were also examined.
The individual factors examined were associated with sexual risk behavior. The cohort was shown to be heterogeneous in regard to the presence of combinations of these risk-related factors.
Baseline data from the EXPLORE study support the efficacy of the individually tailored intervention used.

ABSTRACT: We evaluated factors affecting the feasibility of including young high-risk HIV-negative gay and bisexual men in preventive HIV vaccine trials using data from the U.S. Centers for Disease Control and Prevention Collaborative HIV Seroincidence Study. Of 2189 men enrolled in this study, 17% were <25 years of age. HIV seroincidence was 4.2/100 person-years (95% confidence interval [CI], 2.6-7.0) in young men compared with 2.0/100 person-years (95% CI, 1.4-2.6) for older men. Compared with men 25 and older, young men were more likely to report several high-risk behaviors, to perceive themselves to be at risk for HIV infection, and to report that their risk behavior might be increased by participation in an HIV vaccine trial. The majority of both young men (69%) and older men (74%) expressed willingness in participate in HIV vaccine trials. Young men were less likely to answer questions about vaccine concepts correctly and were more likely to be lost to follow-up. Young gay and bisexual men are important candidates for future HIV vaccine trials, but they may need targeted approaches to recruitment, retention, education about trial concepts prior to enrollment, and behavioral interventions during the trial.
