Background Sexually transmitted disease (STD) prevention remains a public health priority. Simple, practical interventions to reduce STD incidence that can be easily and inexpensively administered in high-volume clinical settings are needed. We evaluated whether a brief video, which contained STD prevention messages targeted to all patients in the waiting room, reduced acquisition of new infections after that clinic visit. Methods and Findings In a controlled trial among patients attending three publicly funded STD clinics (one in each of three US cities) from December 2003 to August 2005, all patients (n = 38,635) were systematically assigned to either a theory-based 23-min video depicting couples overcoming barriers to safer sexual behaviors, or the standard waiting room environment. Condition assignment alternated every 4 wk and was determined by which condition (intervention or control) was in place in the clinic waiting room during the patients first visit within the study period. An intent-to-treat analysis was used to compare STD incidence between intervention and control patients. The primary endpoint was time to diagnosis of incident laboratory-confirmed infections (gonorrhea, chlamydia, trichomoniasis, syphilis, and HIV), as identified through review of medical records and county STD surveillance registries. During 14.8 mo (average) of follow-up, 2,042 patients (5.3%) were diagnosed with incident STD (4.9%, intervention condition; 5.7%, control condition). In survival analysis, patients assigned to the intervention condition had significantly fewer STDs compared with the control condition (hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.84 to 0.99). Conclusions Showing a brief video in STD clinic waiting rooms reduced new infections nearly 10% overall in three clinics. This simple, low-intensity intervention may be appropriate for adoption by clinics that serve similar patient populations. Trial registration: http://www.ClinicalTrials.gov (#NCT00137670).

A longitudinal study of demographic and behavioural characteristics associated with risky sexual behaviours of young men after release from prison. One hundred and six men were interviewed in prison and at one week and six months after release. Overall, 37% reported a previous sexually transmitted disease (STD) diagnosis. In the 30 days before incarceration, 33% had had sex with a risky partner, and 59% had had multiple female sex partners. After release, 38 (36%) men reported having had risky sex (≥2 female sex partners and unprotected vaginal sex): 12 (13%) at one week and 31 (34%) at six months. The only factor independently associated with risky sex was the use of alcohol/drugs before sex: one-week odds ratio (OR)=6.11 (95% confidence interval [CI]: 1.42-26.40), six-month OR=3.05 (95% CI: 1.30-9.42). Behavioural intervention programmes for incarcerated men should address drug and alcohol use and its contribution to higher risk for HIV and STDs.

Objectives: To provide human immunodeficiency virus (HIV) rapid testing to persons in jails, identify previously undiagnosed cases of HIV infection, and refer HIV-infected inmates to care, treatment, and prevention services. Design: Four state health departments (Florida, Louisiana, New York, and Wisconsin) collaborated with jails to implement stand-alone voluntary rapid HIV testing programs. Inmates requested or were referred by medical staff for rapid HIV testing. HIV testing was provided by the health department, correctional facility, or a community-based organization. Inmates whose rapid test was reactive were offered confirmatory testing, medical evaluation, prevention services, and discharge planning. Results: From December 2003 through May 2006, rapid HIV testing was provided to 33,211 inmates, more than 99.9% of whom received their test results. Most of the inmates tested were male (79%), black (58%), and less than 35 years of age (60%). A total of 440 (1.3%) rapid HIV tests were reactive, and 409 (1.2%) of the results were confirmed positive. The testing programs identified 269 (0.8%) previously undiagnosed cases of HIV infection. In the multivariate analyses, new HIV diagnoses were associated with race/ethnicity, report of risky behaviors, and with no report of HIV risk behavior. Almost 40% of diagnoses were for inmates whose only reported risk was heterosexual contact. Conclusions: Rapid HIV testing in jails identified a considerable number of previously undiagnosed cases of HIV infection. Rapid HIV testing should be available to all inmates, regardless of whether inmates reported HIV risky behaviors.

Objectives: The objectives of this study were to describe preincarceration risk behaviors of young men and identify correlates of unprotected sex with multiple partners during the 3 months before incarceration. Study: Data on preincarceration risk behaviors were obtained from 550 men, aged 18 to 29 years, in state prisons in California, Mississippi, Rhode Island, and Wisconsin. Correlates of unprotected sex with multiple partners were determined by logistic regression. Results: Of 550 participants, 71% had multiple sex partners, 65.1% had sex with a partner they perceived as risky, and 45.3% engaged in unprotected sex with multiple partners. Men who drank heavily (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.11–2.54) or who had a risky partner (OR, 3.90; 95% CI, 2.60–5.85) were more likely to report unprotected sex with multiple partners. Men who attended religious gatherings (OR, 0.66; 95% CI, 0.46–0.96) or lived in stable housing (OR, 0.69; 95% CI, 0.48–1.00) were less likely to report unprotected sex with multiple partners. Conclusions: Most participants engaged in behaviors that could result in a sexually transmitted disease, including HIV. Prevention programs should address the relationship between heavy alcohol use and risky sexual behavior. Discharge planning should address housing needs. Faith-based community organizations may play an important role for some young men in their transition to the community.

Background As HIV infection continues unabated, there is a need for effective interventions targeting at-risk men who have sex with men (MSM). Engaging MSM online where they meet sexual partners is critical for HIV prevention efforts. Methods A randomized controlled trial (RCT) conducted online among U.S. MSM recruited from several gay sexual networking websites assessed the impact of 2 HIV prevention videos and an HIV prevention webpage compared to a control condition for the study outcomes HIV testing, serostatus disclosure, and unprotected anal intercourse (UAI) at 60-day follow-up. Video conditions were pooled due to reduced power from low retention (53%, n = 1,631). No participant incentives were provided. Principal Findings Follow-up was completed by 1,631 (53%) of 3,092 eligible men. In the 60 days after the intervention, men in the pooled video condition were significantly more likely than men in the control to report full serostatus disclosure (‘asked and told’) with their last sexual partner (OR 1.32, 95% CI 1.01–1.74). Comparing baseline to follow-up, HIV-negative men in the pooled video (OR 0.70, 95% CI 0.54–0.91) and webpage condition (OR 0.43, 95% CI 0.25–0.72) significantly reduced UAI at follow-up. HIV-positive men in the pooled video condition significantly reduced UAI (OR 0.38, 95% CI 0.20–0.67) and serodiscordant UAI (OR 0.53, 95% CI 0.28–0.96) at follow-up. Conclusions/Significance Findings from this online RCT of MSM recruited from sexual networking websites suggest that a low cost, brief digital media intervention designed to engage critical thinking can increase HIV disclosure to sexual partners and decrease sexual risk. Effective, brief HIV prevention interventions featuring digital media that are made widely available may serve as a complementary part of an overall behavioral and biomedical strategy for reducing sexual risk by addressing the specific needs and circumstances of the target population, and by changing individual knowledge, motivations, and community norms.

HIV and STD risk behavior among 18- to 25-year-old men released from U.S. prisons: provider perspectives.

David W. Seal; Andrew D. Margolis; Jim Sosman; Deborah Kacanek; Diane Binson

Ninety-seven service providers, representing 83 agencies, were interviewed about sexual and drug use HIV/STD risk behaviors and their determinants among young men who have been released from prison. Providers believed that men frequently practiced sexual risk behavior, often in conjunction with substance use. Individual determinants of risk behavior primarily focused on “making up for lost time,” being a man, degree of HIV/STD knowledge and vulnerability, desire to escape, and future orientation. Peers, partners, and family were portrayed as strong interpersonal influences on risk behavior, both positively and negatively. The dominant contextual determinant of risk behavior was the co-occurrence of sex and drug use. Structural determinants of reduced risk included stable housing, economic sufficiency, and positive community support for safer behavior (e.g., drug treatment access, needle exchange). The findings highlight the need for comprehensive, transitional case management for young men as they reintegrate into the community, including HIV/STD prevention.

Are healthcare providers talking to HIV-seropositive patients about safer sex?

Andrew D. Margolis; Richard J. Wolitski; Jeffrey T. Parsons; Cynthia A. Gómez

HIV-seropositive men (n = 250) from San Francisco and New York city completed a self-administered survey assessing health care providers delivery of safer-sex messages. 1 out of 4 men had never received safer-sex counseling from their healthcare provider. Men at highest risk for transmitting HIV were no more likely to have been counseled than men at lower risk. Physicians should regularly provide tailored safer-sex messages to all HIV-seropositive patients who have entrusted them with their care. (authors)

The article describes men’s perceptions of and experience with substance use and sexual behavior during incarceration. Grounded theory content analyses were performed on qualitative interviews conducted with 80 men, aged 18 to 29, in four U.S. states. Participants believed that drugs were easily available in prison. Half reported using substances, primarily marijuana or alcohol, while incarcerated. Key themes included the role of correctional personnel in the flow of substances in prison and the economic significance of substance traffic king. With regard to sexual behavior, most men acknowledged that it occurred but were hesitant to talk in-depth about it. There was a strong belief in “don’t look, don’t tell,” and sex in prison was often associated with homo sexual behavior or identity. Sex during incarceration was reported by 12 men, mostly with female partners. Participants were pessimistic about HIV/STD/hepatitis prevention efforts inside correctional facilities. These findings highlight the need for risk reduction programs for incarcerated men.

Substance Use and Sexual Behavior during Incarceration among 18- to 29-Year Old Men: Prevalence and Correlates

David W. Seal; Andrew D. Margolis; Kathleen M. Morrow; Lisa Belcher; James M. Sosman; John Askew

An A-CASI survey of 197 men with a history of incarceration, ages 18–29, revealed that 50% and 17% of participants, respectively, had used substances or had sex while confined. Univariate regression analyses indicated that these two behaviors were correlated and both were associated with being older, having spent more years incarcerated, being sexual abused, and being involved with gangs and violence during incarceration. Multiple regression analyses showed that the likelihood of any substance use during incarceration was higher for men who were affiliated with a gang. Men were more likely to have had sex during incarceration if they reported having had a male sex partner in the community. The prevalence of sexual behavior also differed across sites. Findings document the occurrence of substance use and sexual behavior among incarcerated men, and highlight the need for continued research into the context of these behaviors.

Girlfriends: evaluation of an HIV-risk reduction intervention for adult transgender women.

Raekiela D. Taylor; David S. Bimbi; Heather A. Joseph; Andrew D. Margolis; Jeffrey T. Parsons

This study evaluated Girlfriends, a behavioral HIV intervention, developed for male-to-female transgender persons, for whom there are few scientifically evaluated prevention programs. The Girlfriends intervention included four group-level sessions. We used a single group, pre-post test design to assess changes in sexual risk behaviors at 3-month follow-up. We enrolled 63 transgender women into the study. Forty-six percent were Hispanic and 35% were African American. Three months after the intervention, participants had fewer sexual partners (p = .043) and were less likely to have any unprotected anal intercourse (UAI) with male exchange partners (p = .013) and unprotected sex at last vaginal or anal sex episode with female and male partners (p = .039). The findings of this study are promising. We observed behavioral effects among a largely ethnic minority sample of transgender women. Replication with a larger sample and a control group is needed.
