Couple-based HIV prevention in the United States: advantages, gaps, and future directions.

This article presents an overview of couple-based HIV prevention research to date, advantages of using and core components of couple-based interventions, gaps in the current understanding of couple-based HIV prevention, status of dissemination research and the transportability of effective couple-based HIV prevention and treatment to real-world settings, and recommendations for future directions in couple-based prevention and treatment. Couple-based studies conducted among several populations-heterosexuals, men who have sex with men, and drug users-reported in the research literature were reviewed. Commonalities and limitations were noted in customary focus areas of the couple-based approaches: sexual and drug risk reduction, HIV testing behaviors, adherence to HIV treatment, and prevention of mother-to-child transmission. Couple-based intervention strategies have been rigorously tested and are a valuable addition to the arsenal of HIV prevention strategies. Immediate needs and opportunities include couple-based intervention strategies for prevention of HIV and other sexually transmitted infections among serodiscordant couples, couples who do not know their HIV status, and couples in whom both partners are HIV negative but at risk of HIV infection. There is a particular need to develop couple-based intervention strategies for men who have sex with men and for drug-involved couples.

Efficacy of a group-based multimedia HIV prevention intervention for drug-involved women under community supervision: project WORTH.

Importance This study is designed to address the need for evidence-based HIV/STI prevention approaches for drug-involved women under criminal justice community supervision. Objective We tested the efficacy of a group-based traditional and multimedia HIV/STI prevention intervention (Project WORTH: Women on the Road to Health) among drug-involved women under community supervision. Design, Setting, Participants, and Intervention We randomized 306 women recruited from community supervision settings to receive either: (1) a four-session traditional group-based HIV/STI prevention intervention (traditional WORTH); (2) a four-session multimedia group-based HIV/STI prevention intervention that covered the same content as traditional WORTH but was delivered in a computerized format; or (3) a four-session group-based Wellness Promotion intervention that served as an attention control condition. The study examined whether the traditional or multimedia WORTH intervention was more efficacious in reducing risks when compared to Wellness Promotion; and whether multimedia WORTH was more efficacious in reducing risks when compared to traditional WORTH. Main Outcomes and Measures Primary outcomes were assessed over the 12-month post-intervention period and included the number of unprotected sex acts, the proportion of protected sex acts, and consistent condom use. At baseline, 77% of participants reported unprotected vaginal or anal sex (n = 237) and 63% (n = 194) had multiple sex partners. Results Women assigned to traditional or multimedia WORTH were significantly more likely than women assigned to the control condition to report an increase in the proportion of protected sex acts (β = 0.10; 95% CI = 0.02–0.18) and a decrease in the number of unprotected sex acts (IRR = 0.72; 95% CI = 0.57–0.90). Conclusion and Relevance The promising effects of traditional and multimedia WORTH on increasing condom use and high participation rates suggest that WORTH may be scaled up to redress the concentrated epidemics of HIV/STIs among drug-involved women in the criminal justice system.

Scaling up HIV prevention efforts targeting people who inject drugs in Central Asia: A review of key challenges and ways forward

BACKGROUND In Central Asia, between 33% and 72% of cumulative HIV infections has been attributed to unsafe injection practices among people who inject drugs (PWID). METHODS We reviewed the current status and trends of national efforts in Central Asian countries to control HIV among PWID, and also reviewed the key structural and health-systems-related challenges that facilitate drug-use-related HIV risk in Central Asia. RESULTS The spectrum and scale of HIV prevention services targeting PWID vary considerably among Central Asian countries. In all countries, the potential impact of these interventions is hindered by several key features: a restrictive legal environment, poor performance of service providers, widespread opposition to harm reduction, deficient human resources and funding mechanisms, poor services integration, insufficient community involvement, and other structural factors. CONCLUSIONS Scaling up HIV prevention interventions in Central Asia will demand greater attention to the structural, health-care-related and social factors that facilitate HIV risk and impede service utilization among PWID. Multi-level combination prevention interventions should be developed with a focus on the sexual partners and risk networks of PWID, aiming at early detection of HIV, timely enrollment in HIV care, and retention in HIV care.

Efficacy of a Computerized Intervention on HIV and Intimate Partner Violence Among Substance-Using Women in Community Corrections: A Randomized Controlled Trial.

OBJECTIVES To test the efficacy of a computerized, group-based HIV and intimate partner violence (IPV) intervention on reducing IPV victimization among substance-using women mandated to community corrections. METHODS Between November 2009 and January 2012, we randomly allocated 306 women from community corrections in New York City to 3 study arms of a computerized HIV and IPV prevention trial: (1) 4 group sessions intervention with computerized self-paced IPV prevention modules (Computerized Women on the Road to Health [WORTH]), (2) traditional HIV and IPV prevention intervention group covering the same HIV and IPV content as Computerized WORTH without computers (Traditional WORTH), and (3) a Wellness Promotion control group. Primary outcomes were physical, injurious, and sexual IPV victimization in the previous 6 months at 12-month follow-up. RESULTS Computerized WORTH participants reported significantly lower risk of physical IPV victimization, severe injurious IPV victimization, and severe sexual IPV victimization at 12-month follow-up when compared with control participants. No significant differences were seen between Traditional WORTH and control participants for any IPV outcomes. CONCLUSIONS The efficacy of Computerized WORTH across multiple IPV outcomes highlights the promise of integrating computerized, self-paced IPV prevention modules in HIV prevention groups.

Redressing the epidemics of opioid overdose and HIV among people who inject drugs in Central Asia: The need for a syndemic approach

BACKGROUND Accumulating evidence suggests that opioid overdose and HIV infection are burgeoning intertwined epidemics among people who inject drugs (PWID) in Central Asia. To date, however, research on overdose and its associations with HIV risks among PWID in Central Asia remains virtually absent. This paper aims to provide a regional overview of the hidden epidemic of overdose and how it is linked to HIV among PWID in Central Asia, using a syndemic framework that is guided by risk environment research. METHODS We conducted a comprehensive literature search of peer-reviewed publications and gray literature on opioid overdose and its associations with HIV in five countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) as well as on policies and programs that address these co-occurring epidemics. RESULTS Regional data indicate high rates of fatal and non-fatal overdose among PWID. Evidence suggests mortality rates from overdose exceed HIV/AIDS as the leading cause of death among PWID. The syndemic framework suggests multiple macro-level and micro-level environmental risk factors that drive the co-occurring epidemics of HIV and overdose. This framework identifies several interacting biological and behavioral risks that result in additive effects for HIV and overdose. CONCLUSION The high rates of overdose and its associations with HIV underscore the need for a syndemic approach that considers overdose on parity with HIV. Such an approach should focus on the biological, behavioral and structural interactions between these epidemics to reduce social suffering, morbidity and mortality among PWID in Central Asia.

The Silk Road Health Project: How Mobility and Migration Status Influence HIV Risks among Male Migrant Workers in Central Asia.

Objectives We examined whether mobility, migrant status, and risk environments are associated with sexually transmitted infections (STIs) and HIV risk behaviors (e.g. sex trading, multiple partners, and unprotected sex). Methods We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility combined with the interaction between mobility and migration status on STIs and sexual risk behaviors, when controlling for risk environment characteristics. Results Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants. Conclusion Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population.

The Promise of Multimedia Technology for STI/HIV Prevention: Frameworks for Understanding Improved Facilitator Delivery and Participant Learning

There is increasing excitement about multimedia sexually transmitted infection (STI) and HIV prevention interventions, yet there has been limited discussion of how use of multimedia technology may improve STI/HIV prevention efforts. The purpose of this paper is to describe the mechanisms through which multimedia technology may work to improve the delivery and uptake of intervention material. We present conceptual frameworks describing how multimedia technology may improve intervention delivery by increasing standardization and fidelity to the intervention material and the participant’s ability to learn by improving attention, cognition, emotional engagement, skills-building, and uptake of sensitive material about sexual and drug risks. In addition, we describe how the non-multimedia behavioral STI/HIV prevention intervention, Project WORTH, was adapted into a multimedia format for women involved in the criminal justice system and provide examples of how multimedia activities can more effectively target key mediators of behavioral change in this intervention.

Feasibility and preliminary effects of a screening, brief intervention and referral to treatment model to address gender-based violence among women who use drugs in Kyrgyzstan: Project WINGS (Women Initiating New Goals of Safety).

INTRODUCTION AND AIMS Intimate partner violence (IPV) and other forms of gender-based violence (GBV) are serious public health threats among women who use drugs or engage in binge drinking in Kyrgyzstan. This study aimed to evaluate the feasibility and preliminary effects of a two-session IPV and GBV screening, brief intervention and referral to treatment model (WINGS) with HIV counselling and testing for women who use drugs or engage in binge drinking in Kyrgyzstan, using a pre/post-design. DESIGN AND METHODS We screened 109 women from harm reduction non-government organisations in Kyrgyzstan, of whom 78 were eligible, 73 participated in the intervention study, and 66 completed a 3-month post-intervention follow-up. To assess the effects of the intervention, we used random-effect Poisson and Logistic regression analyses for continuous and dichotomous outcomes respectively. RESULTS At baseline, 73% reported any physical or sexual IPV victimisation, and 60% reported any physical or sexual GBV victimisation in the past year. At the 3-month follow-up, participants reported experiencing 59% fewer physical IPV incidents in the prior 90 days than at baseline (P < 0.001) and 27% fewer physical GBV incidents than at baseline (P < 0.01). From baseline to the 3-month follow-up, participants also reported a 65% reduction in the odds of using any illicit drugs (P < 0.05) and were more likely to report receiving GBV-related services (P < 0.001). DISCUSSION AND CONCLUSION The high rates of participation, attendance and retention and significant reductions in IPV and GBV victimisation and drug use from baseline to the 3-month follow-up suggest the feasibility and promising effects of this brief intervention.

Implementation of a couple-based HIV prevention program: a cluster randomized trial comparing manual versus Web-based approaches

BackgroundDespite great need, the number of HIV prevention implementation studies remains limited. The challenge for researchers, in this time of limited HIV services agency resources, is to conceptualize and test how to disseminate efficacious, practical, and sustainable prevention programs more rapidly, and to understand how to do so in the absence of additional agency resources. We tested whether training and technical assistance (TA) in a couple-based HIV prevention program using a Web-based modality would yield greater program adoption of the program compared to training and TA in the same program in a manual-based modality among facilitators who delivered the interventions at 80 agencies in New York State.MethodsThis study used a cluster randomized controlled design. Participants were HIV services agencies (N = 80) and up to 6 staff members at each agency (N = 253). Agencies were recruited, matched on key variables, and randomly assigned to two conditions. Staff members participated in a four-day, face-to-face training session, followed by TA calls at two and four months, and follow-up assessments at 6, 12, and 18 months post- training and TA. The primary outcomes examined number of couples with whom staff implemented the program, mean number of sessions implemented, whether staff implemented at least one session or whether staff implemented a complete intervention (all six sessions) of the program. Outcomes were measured at both the agency and participant level.ResultsOver 18 months following training and TA, at least one participant from 13 (33%) Web-based assigned agencies and 19 (48%) traditional agencies reported program use. Longitudinal multilevel analysis found no differences between groups on any outcomes at the agency or participant level with one exception: Web-based agencies implemented the program with 35% fewer couples compared with staff at manual-based agencies (IRR 0.35, CI, 0.13-0.94).ConclusionGreater implementation of a Web-based program may require more resources and staff exposure, especially when paired with a couple-based modality. Manual-based and traditional programs may hold some advantage or ease for implementation, particularly at a time of low economic resources.Trial registrationClinicalTrials.gov identifier: NCT01863537

Men in Community Correction Programs and Their Female Primary Sex Partners: Latent Class Analysis to Identify the Relationship of Clusters of Drug Use and Sexual Behaviors and HIV Risks

Existing research indicates that justice-involved individuals use a variety of different drugs and polysubstance use is common. Research shows that different typologies of drug users, such as polydrug users versus users of a single drug, have differing types of individual-, structural-, and neighborhood-level risk characteristics. However, little research has been conducted on how different typologies of drug use are associated with HIV risks among individuals in community corrections and their intimate sex partners. This paper examines the different types of drug use typologies among men in community correction programs and their female primary sex partners. We used latent class analysis to identify typologies of drug use among men in community correction programs in New York City and among their female primary sex partners. We also examined the associations between drug use typologies with sexual and drug use behaviors that increase the risk of HIV acquisition. The final analysis included a total of 1167 participants (822 male participants and 345 of their female primary sex partners). Latent class analyses identified three identical typologies of drug use for both men and their female primary sex partners: (1) polydrug use, (2) mild polydrug users with severe alcohol and marijuana use, and (3) alcohol and marijuana users. Men and women who were classified as polydrug users and mild polydrug users, compared to those who were classified as alcohol and marijuana users, tended to be older and non-Hispanic Caucasians. Polydrug users and mild polydrug users were also more likely to have risky sex partners and higher rates of criminal justice involvement. There is a need to provide HIV and drug use treatment and linkage to service and care for men in community correction programs, especially polydrug users. Community correction programs could be the venue to provide better access by reaching out to this high HIV risk key population with increased rates of drug use and multiple sex partners.
