Couple-based HIV prevention for low-income drug users from New York City: a randomized controlled trial to reduce dual risks

Counselling behavioural interventions for HIV, STI and viral hepatitis among key populations: a systematic review of effectiveness, values and preferences, and cost studies

INTRODUCTION

Key populations (sex workers, men who have sex with men, people who inject drugs, people in prisons and other closed settings, and trans and gender diverse individuals) are disproportionately affected by HIV, sexually transmitted infections (STIs) and viral hepatitis (VH). Counselling behavioural interventions are widely used, but their impact on HIV/STI/VH acquisition is unclear.

METHODS

To inform World Health Organization guidelines, we conducted a systematic review and meta-analysis of effectiveness, values and preferences, and cost studies about counselling behavioural interventions with key populations. We searched CINAHL, PsycINFO, PubMed and EMBASE for studies published between January 2010 and December 2022; screened abstracts; and extracted data in duplicate. The effectiveness review included randomized controlled trials (RCTs) with HIV/STI/VH incidence outcomes; secondary review outcomes of unprotected sex, needle/syringe sharing and mortality were captured if studies also included primary review outcomes. We assessed the risk of bias using the Cochrane Collaboration tool, generated pooled risk ratios through random effects meta-analysis and summarized findings in GRADE evidence profiles. Values and preferences and cost data were summarized descriptively.

RESULTS

We identified nine effectiveness, two values and preferences, and two cost articles. Meta-analysis of six RCTs showed no statistically significant effect of counselling behavioural interventions on HIV incidence (1280 participants; combined risk ratio [RR]: 0.70, 95% confidence interval [CI]: 0.41-1.20) or STI incidence (3783 participants; RR: 0.99; 95% CI: 0.74-1.31). One RCT with 139 participants showed possible effects on hepatitis C virus incidence. There was no effect on secondary review outcomes of unprotected (condomless) sex (seven RCTs; 1811 participants; RR: 0.82, 95% CI: 0.66-1.02) and needle/syringe sharing (two RCTs; 564 participants; RR 0.72; 95% CI: 0.32-1.63). There was moderate certainty in the lack of effect across outcomes. Two values and preferences studies found that participants liked specific counselling behavioural interventions. Two cost studies found reasonable intervention costs.

DISCUSSION

Evidence was limited and mostly on HIV, but showed no effect of counselling behavioural interventions on HIV/VH/STI incidence among key populations.

CONCLUSIONS

While there may be other benefits, the choice to provide counselling behavioural interventions for key populations should be made with an understanding of the potential limitations on incidence outcomes.

Do Couple-Based Interventions Show Larger Effects in Promoting HIV Preventive Behaviors than Individualized Interventions in Couples? A Systematic Review and Meta-analysis of 11 Randomized Controlled Trials

This systematic review and meta-analysis aims to compare the effects of couple-based prevention interventions against individual-level interventions on HIV prevention in randomized controlled trials (RCTs), identify potential moderators, and assess study quality. Eleven RCTs were included, comprising 3933 couples in the intervention group and 7125 individuals in the individual control group, predominantly in heterosexual couples from the USA and Africa. Couple-based interventions had a more significant effect in promoting condom use and HIV testing. Education levels of high school or above, residence in low- and middle-income countries, and intervention design incorporating HIV counseling and testing were associated with higher odds of condom use. The quality assessment analysis identified methodological and theoretical heterogeneity factors. Evidence of couple-based HIV prevention RCTs among men who have sex with men, injecting drug users, sex workers, and transgender women warrant further investigation. Recommendations are made to improve the quality and replicability of future intervention studies.

Association Between Dual Partnership and Sexual and Injecting Behaviors Among Persons Who Inject Drugs in 23 US Cities, 2018

Persons who inject drugs (PWID) engaging in receptive syringe sharing with their sex partner (dual partnership) may have different behavior patterns than people who have only sex or syringe sharing partnerships. PWID from 23 US cities were recruited for the National HIV Behavioral Surveillance in 2018 using respondent-driven sampling, interviewed, and tested for HIV. Log-linked Poisson regression was conducted to examine the associations between injecting and sexual behaviors and dual partnership. A total of 3435 PWID reported receptive syringe sharing and 42% engaged in dual partnership with their last sharing injecting partner. PWID who reported condomless vaginal or anal sex at last sex were more likely to engage in dual partnership (aPR = 1.85, 95% CI = 1.65-2.08). PWID who reported having two or more sex partners (aPR = 0.67, 95% CI = 0.62-0.72) or two or more sharing injecting partners (aPR = 0.54, 95% CI = 0.50-0.59) were less likely to engage in dual partnership. Findings suggest opportunities for tailored prevention intervention, including couple-based HIV testing, pre-exposure prophylaxis, and access to syringe services programs coupled with safer injection education to help reduce HIV risk.

College-attending young men's sexual and reproductive health knowledge, attitudes and practices

ObjectiveMale involvement in contraceptive practice remains low. Family planning and pediatric health associations have recommended an emphasis on long-acting reversible contraceptives (LARC) in clinical counseling with adolescents and young adults, raising concerns about the resulting adverse impact on sexually transmitted infection (STI) rates. Participants: College-attending men responded to an internet based questionnaire (n=31) and a phone-based qualitative interview (n=25). Methods: Our survey solicited attitudes toward and knowledge of contraceptive methods and assessed communication practices with sexual partners regarding use of contraception and disease prevention. Results: Knowledge about female methods of contraception was low, with a comparatively high level of knowledge about Plan B. Parents and health care providers were cited as the most helpful sources of information. Conversations about protection with sexual partners were reported by most men, due mainly to fear of unplanned pregnancy, not STI. Conclusion: Addressing couple communication and dual protection among college-attending men needs greater emphasis.

What is the added value of incorporating pleasure in sexual health interventions? A systematic review and meta-analysis

Despite billions of dollars invested into Sexual and Reproductive Health and Rights (SRHR) efforts, the effect of incorporating sexual pleasure, a key driver of why people have sex, in sexual health interventions is currently unclear. We carried out a systematic review and meta-analysis following PRISMA guidelines across 7 databases for relevant articles published between 1 January 2005-1 June, 2020. We included 33 unique interventions in our systematic review. Eight interventions reporting condom use outcomes were meta-analyzed together with a method random effects model. Quality appraisal was carried out through the Cochrane Collaborations' RoB2 tool. This study was pre-registered on Prospero (ID: CRD42020201822). We identified 33 unique interventions (18886 participants at baseline) that incorporate pleasure. All included interventions targeted HIV/STI risk reduction, none occurred in the context of pregnancy prevention or family planning. We find that the majority of interventions targeted populations that authors classified as high-risk. We were able to meta-analyze 8 studies (6634 participants at baseline) reporting condom use as an outcome and found an overall moderate, positive, and significant effect of Cohen's d = 0·37 (95% CI 0·20-0·54, p < 0·001; I2 = 48%; τ2 = 0·043, p = 0·06). Incorporating sexual pleasure within SRHR interventions can improve sexual health outcomes. Our meta-analysis provides evidence about the positive impact of pleasure-incorporating interventions on condom use which has direct implications for reductions in HIV and STIs. Qualitatively, we find evidence that pleasure can have positive effects across different informational and knowledge-based attitudes as well. Future work is needed to further elucidate the impacts of pleasure within SRHR and across different outcomes and populations. Taking all the available evidence into account, we recommend that agencies responsible for sexual and reproductive health consider incorporating sexual pleasure considerations within their programming.

Expanding the continuum of substance use disorder treatment: Nonabstinence approaches

Only a small minority of people with substance use disorders (SUDs) receive treatment. A focus on abstinence is pervasive in SUD treatment, defining success in both research and practice, and punitive measures are often imposed on those who do not abstain. Most adults with SUD do not seek treatment because they do not wish to stop using substances, though many also recognize a need for help. This narrative review considers the need for increased research attention on nonabstinence psychosocial treatment of SUD - especially drug use disorders - as a potential way to engage and retain more people in treatment, to engage people in treatment earlier, and to improve treatment effectiveness. We describe the development of nonabstinence approaches within the historical context of SUD treatment in the United States, review theoretical and empirical rationales for nonabstinence SUD treatment, and review existing models of nonabstinence psychosocial treatment for SUD among adults to identify gaps in the literature and directions for future research. Despite significant empirical support for nonabstinence alcohol interventions, there is a clear gap in research examining nonabstinence psychosocial treatment for drug use disorders. Future research must test the effectiveness of nonabstinence treatments for drug use and address barriers to implementation.

Applying a Nursing Perspective to Address the Challenges Experienced by Cisgender Women in the HIV Status Neutral Care Continuum: A Review of the Literature

ABSTRACT

The field of HIV research has grown over the past 40 years, but there remains an urgent need to address challenges that cisgender women living in the United States experience in the HIV neutral status care continuum, particularly among women such as Black women, who continue to be disproportionately burdened by HIV due to multiple levels of systemic oppression. We used a social ecological framework to provide a detailed review of the risk factors that drive the women's HIV epidemic. By presenting examples of effective approaches, best clinical practices, and identifying existing research gaps in three major categories (behavioral, biomedical, and structural), we provide an overview of the current state of research on HIV prevention among women. To illustrate a nursing viewpoint and take into account the diverse life experiences of women, we provide guidance to strengthen current HIV prevention programs. Future research should examine combined approaches for HIV prevention, and policies should be tailored to ensure that women receive effective services that are evidence-based and which they perceive as important to their lives.

Use of a Novel Couples' Verification Tool in a Male Partner Treatment Study of Women With Recurrent Bacterial Vaginosis

Verification of relationship status beyond self-report is an important aspect in sexually transmitted infection research, including partner treatment studies where primary sexual partners are targeted for enrollment. This exploratory study describes the use of a novel couples' verification tool in a male partner treatment study of women with recurrent bacterial vaginosis.

Effects of Social Support and 12-Step Involvement on Recovery among People in Continuing Care for Cocaine Dependence

Background: Social networks that support recovery lead to enhanced treatment outcomes and sobriety regardless if this support stems from family, peer groups or 12-Step programs. Treatment process factors including readiness to change and commitment to abstinence also impact substance use. However, little is understood about the relationship between social support to treatment process factors during and after treatment for substance use disorders. Objectives: To identify the ways in which different social networks foster substance use change in a sample of individuals with cocaine dependence from intensive outpatient programs (IOPs). Methods: Data were drawn from two studies examining adults (N = 489) with cocaine dependence in IOPs for substance use disorders collected between 2004 and 2009. Assessment data were collected at 3- to 6-month intervals from baseline to 24-months and included the University of Rhode Island change assessment questionnaire, timeline followback, thoughts about abstinence, perceived social support - friend, and family versions and analyzed using GEE and mediational analyses. Results: Greater perceived friend social support was associated with greater readiness to change whereas greater perceived familial social support was associated with substance use goal; greater social support from both friends and family were associated with less substance use. Greater AA/NA participation was associated with substance use goal and readiness to change, and less substance use. Substance use goals partially mediated the impact of social support on later substance use. Conclusions/Importance: While peer and familial support are key to sustained recovery, their impact differentially affects treatment process variables. This information could be used to inform social support treatment interventions.

Effectiveness of a Couple-Based HIV and Sexually Transmitted Infection Prevention Intervention for Men in Community Supervision Programs and Their Female Sexual Partners: A Randomized Clinical Trial

IMPORTANCE

In the United States, the prevalence rates of HIV and sexually transmitted infections (STIs) are higher among individuals in community supervision programs (CSPs) than in the general population. However, to date, no couple-based HIV or STI prevention interventions have been implemented for the large number of men in CSPs.

OBJECTIVE

To determine the effectiveness of a 5-session couple-based prevention intervention, compared with a 1-session counseling, testing, and referral (CTR) program, in reducing HIV and STIs as well as condomless intercourse among men in CSPs and their female sexual partners.

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial was conducted from July 11, 2013 (first recruitment), through May 17, 2016 (last randomization). Participants were drug-involved men mandated to a CSP and their female sexual partners (n = 230 couples or 460 individuals). Participants were recruited from various CSP sites in New York, New York, and randomized into either the PACT (Protect and Connect) intervention condition or the HIV CTR control condition (n = 115 couples or 230 individuals in each arm). Analysis of behavioral outcomes used an intent-to-treat approach. Statistical analyses were conducted from November 1, 2017, through June 1, 2018.

MAIN OUTCOMES AND MEASURES

Self-reported data on sexual behaviors in the past 90 days were used to assess behavioral outcomes at all time points. Biomarkers were collected at baseline and 12 months, and behavioral outcomes were collected at baseline and 3, 6, and 12 months.

RESULTS

A total of 230 couples (460 individuals) were included. The mean (SD) age of participants was 35.0 (12.8) years, and most participants (341 [74.1%]) self-identified as black or African American race/ethnicity. Of the 18 new cases of STIs identified at the 12-month assessment, 10 came from the PACT arm and 8 from the HIV CTR control arm. Compared with the control participants, PACT participants had 33% fewer acts of condomless vaginal and/or anal intercourse with their main partner (incidence rate ratio [IRR], 0.67; 95% CI, 0.45-0.99; P = .04), 70% fewer acts with other partners (IRR, 0.30; 95% CI, 0.12-0.74; P = .009), and 40% fewer acts with all sexual partners (IRR, 0.60; 95% CI, 0.42-0.85; P = .005) over the entire follow-up period. In addition, PACT participants were less likely to report being under the influence of drugs or alcohol the last time they had vaginal and/or anal intercourse with their study partners (odds ratio, 0.55; 95% CI, 0.31-0.96; P = .04) and had 26% fewer sexual partners in the past 90 days (IRR, 0.74; 95% CI, 0.61-0.88; P = .001). At 12 months, HIV and STI incidence did not differ significantly between the 2 arms.

CONCLUSIONS AND RELEVANCE

The PACT intervention appeared to reduce risky sexual behaviors, such as condomless intercourse; this finding suggests that a couple-based HIV and STI prevention intervention program may curb the burgeoning HIV epidemic in CSPs.

Dissolution of Committed Partnerships during Incarceration and STI/HIV-Related Sexual Risk Behavior after Prison Release among African American Men

Incarceration is strongly associated with post-release STI/HIV risk. One pathway linking incarceration and STI/HIV risk may be incarceration-related dissolution of protective network ties. Among African American men released from prison who were in committed partnerships with women at the time of incarceration (N = 207), we measured the association between committed partnership dissolution during incarceration and STI/HIV risk in the 4 weeks after release. Over one-quarter (28%) experienced incarceration-related partnership dissolution. In adjusted analyses, incarceration-related partnership dissolution was strongly associated with post-release binge drinking (adjusted odds ratio (AOR) 4.2, 95% confidence interval (CI); 1.4-15.5). Those who experienced incarceration-related partnership dissolution were much more likely to engage in multiple/concurrent partnerships or sex trade defined as buying or selling sex (64%) than those who returned to the partner (12%; AOR 20.1, 95% CI 3.4-175.6). Policies that promote maintenance of relationships during incarceration may be important for protecting health.

Gay and Bisexual Men's Perceptions of HIV Risk in Various Relationships

Men who have sex with men (MSM) bear a disproportionate burden of HIV incidence in the United States. Previous study of sexual decision-making and HIV risk among MSM has not accounted for relationship dynamics. Further research must examine this connection between relationship dynamics and sexual decision-making, especially regarding condomless anal intercourse. This study analyzes data gathered from gay and bisexual men regarding their sexual partners and sexual decision-making over a 10-week period through personal relationship diaries (PRDs) and a follow-up in-depth interview (IDI). Through coding and extraction of relationship dynamics, key patterns of participants' sexual decision-making processes were examined based on relationship type, which was categorized by commitment, formality, and sexual agreement. Participants' sexual relationships can be divided into five categories: (a) Uncommitted, one time, (b) Uncommitted, ongoing, (c) Transitioning or unknown commitment, (d) Committed, nonmonogamous, and (e) Committed, monogamous. These five categories correspond to patterns in sexual decision making and consequent sexual risk-taking behaviors. Each of these influence HIV risk within male-male sexual encounters in a particular manner, and understanding these is important for appropriately tailored HIV prevention interventions for MSM. Recommendations are included for interventions seeking to address HIV risk across a wide variety of MSM sexual relationships.

Heterosexual male and female disparities in HIV infection at the end of an epidemic: HIV infection among persons who inject drugs in New York City, 2001-2005 and 2011-2015

BACKGROUND

We examined whether sex disparities (heterosexual male:female) in HIV infection continue to persist at the "end of the HIV epidemic" among persons who inject drugs (PWID) in New York City (NYC). An "end of the epidemic" was operationally defined as 1) prevalence of untreated HIV infection <5%, and 2) estimated HIV incidence <0.5/100 person-years.

METHODS

PWID were recruited from persons entering substance use treatment programs at Mount Sinai Beth Israel in 2001-2005 and 2011-2015. A structured interview was administered, and HIV and HSV-2 testing was conducted. Incidence was estimated using newly diagnosed cases of HIV. Disparity analyses compared prevalence of HIV, of untreated HIV, HIV risk behaviors, and estimated HIV incidence.

RESULTS

By 2011-2015, both heterosexual male and female PWID met the two criteria for an "end of the epidemic," and there were no significant differences in the prevalence of untreated HIV infection. A large sex difference remained in estimated HIV incidence. In 2013-2015, estimated HIV incidence was 2.8/10,000 PY for males and 7.1/10,000 PY for females. Females had greater risk for HIV on several factors.

CONCLUSION

While NYC has reached an "end of the epidemic" for both heterosexual male and female PWID, sex disparities persist, particularly differences in HIV incidence. Eliminating the sex disparities may require a greater focus on factors associated with sexual transmission.

Reducing opioid overdose in Kazakhstan: A randomized controlled trial of a couple-based integrated HIV/HCV and overdose prevention intervention "Renaissance"

OBJECTIVES

To evaluate the efficacy of a couple-based integrated HIV/HCV and overdose prevention intervention on non-fatal and fatal overdose and overdose prevention behaviors among people who use heroin or other opioids in Almaty, Kazakhstan.

METHODS

We selected 479 participants who reported lifetime heroin or opioid use from a sample of 600 participants (300 couples) enrolled in a randomized controlled trial (RCT) conducted between May 2009 and February 2013. Participants were randomized to either (1) a 5-session couple-based HIV/HCV and overdose prevention intervention condition or (2) a 5-session Wellness Promotion and overdose prevention comparison condition. We used multilevel mixed-effects model with modified Poisson regression to estimate effects of the intervention as risk ratios (RR) and the corresponding 95% CIs.

RESULTS

About one-fifth (21.9%) of the sample reported that they had experienced an opioid overdose in the past 6 months at baseline. At the 12-month follow-up, both the intervention and comparison conditions reported significant reductions in non-fatal overdose and injection heroin/opioid use and significant increases in drug treatment attendance and naloxone use to prevent death from overdose. However, we found no differences between the study arms on any of these outcomes. There were three intervention condition participants (1.3%), compared to seven comparison condition participants (2.9%) who died from opioid overdose during the 12-month follow up period although this difference was not significant.

DISCUSSION

There were no significant conditions on any outcomes: both conditions showed promising effects of reducing non-fatal overdose and overdose risks. Integrating overdose prevention into a couple-based HIV/HCV intervention may be an efficient strategy to target the syndemic of opioid overdose, HIV and HCV in Kazakhstan.

Modeling the Intervention of HIV Transmission across Intertwined Key Populations

The HIV transmissions between multiple key populations make interventions difficult, particularly with multiple transmission behaviors. It remains unclear how significant the role of bridge individuals (who connect multiple communities) is in HIV transmission, and how to develop more effective intervention strategies targeting different transmission modes across key populations. In this research, we proposed a 2-layer social network framework to simulate the HIV transmissions across female sex workers (FSWs) and persons who inject drugs (PWID) through two behaviors: unprotected sex and needle-sharing. We proposed a set of intervention strategies based on the topological properties of individuals in the social network and estimated the efficacy of these strategies. Simulation studies demonstrated that bridge individuals played a significant role in HIV transmissions across the two networks. Prevention on such bridge individuals could help reduce both the scale and speed of HIV transmissions.

Preventing blood-borne virus infection in people who inject drugs in the UK: systematic review, stakeholder interviews, psychosocial intervention development and feasibility randomised controlled trial

BACKGROUND

Opioid substitution therapy and needle exchanges have reduced blood-borne viruses (BBVs) among people who inject drugs (PWID). Some PWID continue to share injecting equipment.

OBJECTIVES

To develop an evidence-based psychosocial intervention to reduce BBV risk behaviours and increase transmission knowledge among PWID, and conduct a feasibility trial among PWID comparing the intervention with a control.

DESIGN

A pragmatic, two-armed randomised controlled, open feasibility trial. Service users were Steering Group members and co-developed the intervention. Peer educators co-delivered the intervention in London.

SETTING

NHS or third-sector drug treatment or needle exchanges in Glasgow, London, Wrexham and York, recruiting January and February 2016.

PARTICIPANTS

Current PWID, aged ≥ 18 years.

INTERVENTIONS

A remote, web-based computer randomisation system allocated participants to a three-session, manualised, psychosocial, gender-specific group intervention delivered by trained facilitators and BBV transmission information booklet plus treatment as usual (TAU) (intervention), or information booklet plus TAU (control).

MAIN OUTCOME MEASURES

Recruitment, retention and follow-up rates measured feasibility. Feedback questionnaires, focus groups with participants who attended at least one intervention session and facilitators assessed the intervention's acceptability.

RESULTS

A systematic review of what works to reduce BBV risk behaviours among PWID; in-depth interviews with PWID; and stakeholder and expert consultation informed the intervention. Sessions covered improving injecting technique and good vein care; planning for risky situations; and understanding BBV transmission. Fifty-six per cent (99/176) of eligible PWID were randomised: 52 to the intervention group and 47 to the control group. Only 24% (8/34) of male and 11% (2/18) of female participants attended all three intervention sessions. Overall, 50% (17/34) of men and 33% (6/18) of women randomised to the intervention group and 47% (14/30) of men and 53% (9/17) of women randomised to the control group were followed up 1 month post intervention. Variations were reported by location. The intervention was acceptable to both participants and facilitators. At 1 month post intervention, no increase in injecting in 'risky' sites (e.g. groin, neck) was reported by participants who attended at least one session. PWID who attended at least one session showed a trend towards greater reduction in injecting risk behaviours, a greater increase in withdrawal planning and were more confident about finding a vein. A mean cost of £58.17 per participant was calculated for those attending one session, £148.54 for those attending two sessions and £270.67 for those attending all three sessions, compared with £0.86 in the control group. Treatment costs across the centres vary as a result of the different levels of attendance, as total session costs are divided by attendees to obtain a cost per attendee. The economic analysis suggests that a cost-effectiveness study would be feasible given the response rates and completeness of data. However, we have identified aspects where the service use questionnaire could be abbreviated given the low numbers reported in several care domains. No adverse events were reported.

CONCLUSIONS

As only 19% of participants attended all three intervention sessions and 47% were followed up 1 month post intervention, a future definitive randomised controlled trial of the intervention is not feasible. Exposure to information on improving injecting techniques did not encourage riskier injecting practices or injecting frequency, and benefits were reported among attendees. The intervention has the potential to positively influence BBV prevention. Harm reduction services should ensure that the intervention content is routinely delivered to PWID to improve vein care and prevent BBVs.

FUTURE WORK

The intervention did not meet the complex needs of some PWID, more tailoring may be needed to reach PWID who are more frequent injectors, who are homeless and female.

LIMITATIONS

Intervention delivery proved more feasible in London than other locations. Non-attendance at the York trial site substantially influenced the results.

'Love and trust, you can be blinded': HIV risk within relationships among Latina women in Miami, Florida

OBJECTIVES

Latina women are disproportionately affected by HIV in the US, and account for 30% of all HIV infections in Miami-Dade County, Florida. The main risk for Latina women is heterosexual contact. Little is known about the relational and cultural factors that may impact women's HIV risk perception. This study aims to describe Latina women's perception of their HIV risk within a relational, cultural, and linguistic context.

DESIGN

Eight focus groups of Latina women (n = 28), four English speaking groups and four Spanish speaking groups, were conducted between December 2013 and May 2014. Women were recruited from a diversion program for criminal justice clients and by word of mouth. Eligibility criteria included the following: self-identify as Hispanic/Latino, 18-49 years of age, and self-identify as heterosexual. A two-level open coding analytic approach was conducted to identify themes across groups.

RESULTS

Most participants were foreign-born (61%) and represented the following countries: Cuba (47%), Honduras (17.5%), Mexico (12%), as well as Nicaragua, Puerto Rico, Colombia, and Venezuela (15%). Participant ages ranged between 18 and 49, with a mean age of 32 years. Relationship factors were important in perceiving HIV risk including male infidelity, women's trust in their male partners, relationship type, and getting caught up in the heat of the moment. For women in the English speaking groups, drug use and trading sex for drugs were also reasons cited for putting them at risk for HIV. English speaking women also reported that women should take more responsibility regarding condom use.

CONCLUSION

Findings emphasize the importance of taking relational and cultural context into account when developing HIV prevention programs for Latina women. Interventions targeting English speaking Latina women should focus on women being more proactive in their sexual health; interventions focused on Spanish speaking women might target their prevention messages to either men or couples.

The Committed Intimate Partnerships of Incarcerated African-American Men: Implications for Sexual HIV Transmission Risk and Prevention Opportunities

Incarceration is thought to influence HIV transmission by disrupting partnerships that provide support and protect against sex risk-taking. Current correctional facility-based family-strengthening programs focus on marital partnerships, a minority of inmates' partnerships. Research on the sex partnerships of incarcerated African-American men and the types of partnerships most likely to protect against HIV-related sex risk is limited. Improved understanding can inform expansion of correctional facility-based family-strengthening programs to a greater proportion of protective partnerships and HIV risk reduction programs to partnerships vulnerable to sex risk. Project DISRUPT is a cohort study of African-American men being released from prison in North Carolina who were in committed heterosexual partnerships at prison entry. Using baseline survey data (N = 189), we conducted latent class analysis (LCA) to identify subgroups of participants with distinct relationship profiles and measured associations between relationship characteristics and multiple partnerships of inmates and their partners in the six months before incarceration. LCA indicated a two-class solution, with relationships distinguished by satisfaction/stability (satisfied/stable class: 58.0%; dissatisfied/unstable class: 42.0%); each class had comparable relationship length and levels of marriage and cohabitation. Dissatisfied/unstable relationships were associated with multiple partnerships among participants (AOR 2.93, 95% CI 1.50, 5.72) and partners (AOR 4.95, 95% CI 1.68, 14.58). Satisfaction indicators-versus length, marriage, or cohabitation-were the strongest independent correlates of inmates' and partners' multiple partnerships. Pre-incarceration economic deprivation, mental disorder symptoms, substance use, and violence in relationships were associated with dissatisfaction/instability. Prison-based programs designed to maintain healthy partnerships, strengthen relationship skills, and reduce HIV risk-taking and violence in relationships are warranted and should be targeted to both marital and nonmarital partnerships. Programming also should address the poverty, mental illness, and substance use factors that threaten relationship satisfaction/stability and increase HIV risk.

A Systematic Review and Meta-analysis of Psychosocial Interventions to Reduce Drug and Sexual Blood Borne Virus Risk Behaviours Among People Who Inject Drugs

Opiate substitution treatment and needle exchanges have reduced blood borne virus (BBV) transmission among people who inject drugs (PWID). Psychosocial interventions could further prevent BBV. A systematic review and meta-analysis examined whether psychosocial interventions (e.g. CBT, skills training) compared to control interventions reduced BBV risk behaviours among PWID. 32 and 24 randomized control trials (2000-May 2015 in MEDLINE, PsycINFO, CINAHL, Cochrane Collaboration and Clinical trials, with an update in MEDLINE to December 2016) were included in the review and meta-analysis respectively. Psychosocial interventions appear to reduce: sharing of needles/syringes compared to education/information (SMD −0.52; 95% CI −1.02 to −0.03; I² = 10%; p = 0.04) or HIV testing/counselling (SMD −0.24; 95% CI −0.44 to −0.03; I² = 0%; p = 0.02); sharing of other injecting paraphernalia (SMD −0.24; 95% CI −0.42 to −0.06; I² = 0%; p < 0.01) and unprotected sex (SMD −0.44; 95% CI −0.86 to −0.01; I² = 79%; p = 0.04) compared to interventions of a lesser time/intensity, however, moderate to high heterogeneity was reported. Such interventions could be included with other harm reduction approaches to prevent BBV transmission among PWID.

Challenges to Practicing HIV Sex-Risk Prevention Among People in Continuing Care for Cocaine Addiction

BACKGROUND

Intimate partnerships are discouraged during early recovery, despite research that highlights their capacity to be resources for change.

OBJECTIVE

This study seeks to provide descriptions of intimate partnerships and how such partnerships challenge and/or support minimizing HIV sex-risk among participants in continuing care for cocaine addiction in order to inform substance use programming.

METHODS

Forty-two recorded continuing care counseling sessions of 33 people who discussed HIV sex-risk behavior were transcribed and analyzed using thematic analysis. This sample was derived from a larger randomized controlled trial that looked at the impact of a continuing care intervention for people with cocaine use problems.

RESULTS

Although participants expressed the desire for a primary intimate partnership, casual intimate partnerships that often involved HIV sex-risk behavior were more prevalent. Challenges to having a primary intimate partner included the belief that intimate partnerships do not support recovery, difficulty in developing friendships with women among heterosexual men, and the ubiquity of drug use and sex work in home environments with limited economic opportunity. Despite these challenges, some participants reported having primary intimate partners that supported their recovery through open communication.

CONCLUSION

Clinicians providing substance use interventions can consider encouraging components of intimate partnerships that support recovery. In addition, the strong environmental influence on individual HIV sex-risk behavior should be considered in delivering any substance use intervention.

Female Partner Acceptance as a Predictor of Men's Readiness to Undergo Voluntary Medical Male Circumcision in Zambia: The Spear and Shield Project

The World Health Organization has recommended the scale-up of voluntary medical male circumcision (VMMC) for HIV prevention in sub-Saharan Africa; however, men are often uninterested in undergoing VMMC. The Spear & Shield project enrolled 668 men and female partners from ten Zambian community health centers into parallel interventions promoting VMMC for HIV prevention or time-matched control conditions. A mediation model was utilized to examine the relationships between changes in women's acceptance of VMMC and men's readiness to undergo the procedure. Results demonstrated that, at 12 months post-intervention, a 5.9 % increase in the likelihood of undergoing VMMC among men in the experimental condition could be attributed to increased women's acceptance. From a public health perspective, involving women in VMMC promotion interventions such as the Spear & Shield project could significantly impact the demand for VMMC in Zambia.

The male factor: Outcomes from a cluster randomized field experiment with a couples-based HIV prevention intervention in a South African township

BACKGROUND

This study examined the effects of the Couples Health CoOp intervention on heavy drinking, condom use, and HIV incidence.

METHODS

Thirty neighborhoods from one South African township were cluster randomized into three intervention arms: Couples Health CoOp (CHC), Women's Health CoOp/Men's Health CoOp (WHC/MHC), or a comparison arm. We recruited 290 men from informal drinking establishments who reported drinking alcohol regularly. We also recruited their main heterosexual sex partners.

RESULTS

At 6-month follow-up, men in the CHC arm were less likely to report heavy drinking (OR 0.47, 95% CI: 0.25, 0.90) and were more likely to report consistent condom use during the past month (OR 2.66, 95% CI: 1.23, 5.76) than men in the comparison arm. At baseline, 26% of women and 13% of men were HIV-infected; at 6-month follow-up, 16 females and 5 males had seroconverted. HIV incidence was significantly lower among women in the CHC arm (IRR 0.22, 95% CI: 0.04, 1.01) than in the WHC/MHC arm.

CONCLUSIONS

A couples-based intervention focusing on intersecting risks for HIV can improve biobehavioral outcomes, underscoring the importance of engaging couples together in HIV prevention.

Acceptability of Couples' Voluntary HIV Testing Among HIV-infected Patients in Care and Their HIV-negative Partners in the United States

Introduction:

Couples’ voluntary HIV counseling and testing (CHTC) is an HIV risk reduction strategy not widely available in the US.

Methods:

We assessed willingness to participate in CHTC among US HIV-infected clinic patients via tablet-based survey and among HIV-negative persons with HIV-infected partners in care via mixed-method phone interviews.

Results:

Most of the N=64 HIV-infected partners surveyed were men (89%), on antiretroviral treatment (ART) (92%), and many self-identified homosexual (62%). We observed high levels of willingness to participate in CHTC (64%) among HIV-infected partners. Reasons for not wanting to participate included perceived lack of need (26%), desire to self-disclose their status (26%), and fear of being asked sensitive questions with their partner present (17%). HIV-infected partners were interested in discussing ART (48%), other sexually transmitted infections (STIs) (44%), and relationship agreements like monogamy (31%) during CHTC sessions. All N=15 HIV-negative partners interviewed were men, most identified as homosexual (73%), and about half (54%) reported consistent condom use with HIV-infected partners. We observed high levels of willingness to participate in CHTC (87%) among HIV-negative partners, who were also interested in discussing ART (47%), other STIs (47%), mental health services (40%), and relationship agreements (33%). Most negative partners (93%) indicated that they believed their HIV-infected partner was virally suppressed, but in the event that they were not, many (73%) were willing to take pre-exposure prophylaxis (PrEP).

Conclusion:

These results indicate that CHTC for serodiscordant couples is acceptable and should emphasize aspects most pertinent to these couples, such as discussion of ART/PrEP, STIs, and relationship agreements.

Social and Structural Challenges to Drug Cessation Among Couples in Northern Mexico: Implications for Drug Treatment in Underserved Communities

BACKGROUND

Available drug treatment modalities may inadequately address social and structural contexts surrounding recovery efforts.

METHODS

This mixed methods analysis drew on (1) surveys with female sex workers and their intimate male partners and (2) semi-structured interviews with a subsample of 41 couples (n=82 individuals, 123 total interviews) in Northern Mexico. Descriptive and content analyses examined drug cessation and treatment experiences.

RESULTS

Perceived need for drug treatment was high, yet only 35% had ever accessed services. Financial and institutional barriers (childcare needs, sex-segregated facilities) prevented partners from enrolling in residential programs together or simultaneously, leading to self-treatment attempts. Outpatient methadone was experienced more positively, yet financial constraints limited access and treatment duration. Relapse was common, particularly when one partner enrolled alone while the other continued using drugs.

CONCLUSIONS

Affordable, accessible, evidence-based drug treatment and recovery services that acknowledge social and structural contexts surrounding recovery are urgently needed for drug-involved couples.

The micro-social risk environment for injection drug use: An event specific analysis of dyadic, situational, and network predictors of injection risk behavior

BACKGROUND

This study explores the risk environment for drug use by examining injection risk behavior during specific injection episodes. By leveraging multiple observations of injection episodes of participants, the study attempts to move beyond global assessment of environmental variables to simultaneously model within (i.e., event level) as well as between (i.e., individual level) predictors of injection risk. Furthermore, gender is also explored as a potential moderator of the relationship between the association of specific partner characteristics (e.g., having an injection partner who is also a sexual partner) and injection risk behavior.

METHODS

Data is used from the Sexual Acquisition of Transmission of HIV Cooperative Agreement Study (SATHCAP). Multilevel structural equation modeling is utilized to predict within and between variations in underlying injection risk behavior as measured using four indicators of injection risk.

RESULTS

Results indicated that a number of partner level characteristics (i.e., being emotionally close with the partner, sexual partnership, being a first time partner) and one social situational (i.e., the number of non-injectors present at the injection episode) characteristic predicted event level injection risk behavior. However, the impact of partner characteristics also appears to be moderated by gender of the participants. More specifically, sharing a sexual partnership with an injection partner was more strongly associated with injection risk among females as compared to males and females indicated higher levels of risk when injecting with other females while the partner's gender showed no significant association with risk for male injectors.

CONCLUSION

These results suggest that people who inject drug do report varying levels of risk during different injection episodes and this variation can be explained by partner and situational characteristics. Improved understanding of the social processes surrounding injection episodes is required to further refine harm reduction approaches.

Feasibility and initial efficacy of a culturally sensitive women-centered substance use intervention in Georgia: Sex risk outcomes

BACKGROUND

This paper reports on the feasibility and initial efficacy of a culturally sensitive, comprehensive women-centered substance use intervention for women who inject drugs in Georgia in terms of the primary and secondary sex risk outcomes. The hypothesis under examination was that, relative to case management participants, participants in a culturally sensitive, comprehensive women-specific and -centered intervention would, on average, show significant decreases in past-30-day frequency of unprotected sex, unprotected sex at the last sexual encounter, and increases in condom use and safer sex actions.

METHODS

The study was a two-arm randomized trial, in which 173 potentially eligible women were screened, and those 128 women determined to be eligible were assigned at random to either Reinforcement-based Treatment plus Women's Co-Op (RBT + WC) or case management (CM). RBT + WC participants received 12 sessions of a structured intervention with the goal of reducing risky sex and substance use and improving physical and mental health. CM participants received 12 sessions of case management and informational brochures that focused on the same issues on which RBT + WC focused. Participants were assessed at baseline, post-treatment, and 3 months following treatment enrollment.

RESULTS

Analyses revealed case management having significantly overall higher Safer Sex action scores than RBT + WC, and a significant decrease over time for past 30-day number of unprotected sex acts. Unprotected sex at the last encounter and Condom Use action scores were nonsignificant.

CONCLUSIONS

Women who inject drugs in Georgia are engaging in risky sexual practices, and are in need of an intervention that addresses these risky behaviors. Reasons for the failure to find differences between a culturally sensitive, comprehensive women-centered intervention and case management tailored to the needs of women who inject drugs in Georgia may have been the result of inadequate power to detect an effect in a sample whose drug use was not as serious as warranted by the intervention.

The role of dyad-level factors in shaping sexual and drug-related HIV/STI risks among sex workers with intimate partners

BACKGROUND

Despite high HIV burden among sex workers (SWs) globally, and relatively high prevalence of client condom use, research on potential HIV/STI risk pathways of intimate partnerships is limited. This study investigated partner/dyad-level factors associated with inconsistent condom use among SWs with intimate partners in Vancouver, Canada.

METHODS

Baseline data (2010-2013) were drawn from a community-based prospective cohort of women SWs. Multivariable generalized estimating equations logistic regression examined dyad-level factors associated with inconsistent condom use (<100% in last six months) with up to three male intimate partners per SW. Adjusted odds ratios and 95% confidence intervals were reported (AOR[95%CI]).

RESULTS

Overall, 369 SWs reported having at least one intimate partner, with 70.1% reporting inconsistent condom use. Median length of partnerships was 1.8 years, with longer duration linked to inconsistent condom use. In multivariable analysis, dyad factors significantly associated with increased odds of inconsistent condom use included: having a cohabiting (5.43[2.53-11.66]) or non-cohabiting intimate partner (2.15[1.11-4.19]) (versus casual partner), providing drugs (3.04[1.47-6.30]) or financial support to an intimate partner (2.46[1.05-5.74]), physical intimate partner violence (2.20[1.17-4.12]), and an intimate partner providing physical safety (2.08[1.11-3.91]); non-injection drug use was associated with a 68% reduced odds (0.32[0.17-0.60]).

CONCLUSIONS

Our study highlights the complex role of dyad-level factors in shaping sexual and drug-related HIV/STI risk pathways for SWs from intimate partners. Couple and gender-focused interventions efforts are needed to reduce HIV/STI risks to SWs through intimate partnerships. This research supports further calls for integrated violence and HIV prevention within broader sexual/reproductive health efforts for SWs.

Are couple-based interventions more effective than interventions delivered to individuals in promoting HIV protective behaviors? A meta-analysis

Despite several advantages to bringing couples together to learn how to protect themselves and new-born children from the risk of HIV infection, most interventions are designed for individuals or groups, not for dyads. This meta-analysis provides a direct test of whether couple-based interventions are more effective in promoting HIV protective behaviors than interventions delivered to individuals. We conducted systematic searches of five electronic databases and 60 journals. Eligible studies were controlled trials or prospective cohort designs; evaluated a couple-based intervention compared to an individual-level intervention; assessed at least one HIV prevention outcome (e.g., protective sex, drug use, HIV testing, medication adherence, and sexually transmitted infections [STI]); and were published between 1988 and 2014. Fifteen interventions, including 21,882 participants from China, Kenya, Rwanda, Tanzania, Trinidad, Zambia, and the USA, were evaluated. The results of random-effects models showed statistically significant intervention effects for protective sex (OR = 1.60, 95% CI = 1.21, 2.11), HIV testing (OR = 1.79, 95% CI = 1.31, 2.45), and Nevirapine uptake (OR = 1.51, 95% CI = 1.02, 2.24). The evidence demonstrates the usefulness of couple-based interventions in protecting individuals, partners, and new-born children from the risk of HIV transmission and infection.

Advances in HIV prevention for serodiscordant couples

Serodiscordant couples play an important role in maintaining the global HIV epidemic. This review summarizes biobehavioral and biomedical HIV prevention options for serodiscordant couples focusing on advances in 2013 and 2014, including World Health Organization guidelines and best evidence for couples counseling, couple-based interventions, and the use of antiviral agents for prevention. In the past few years, marked advances have been made in HIV prevention for serodiscordant couples and numerous ongoing studies are continuously expanding HIV prevention tools, especially in the area of pre-exposure prophylaxis. Uptake and adherence to antiviral therapy remains a key challenge. Additional research is needed to develop evidence-based interventions for couples, and especially for male-male couples. Randomized trials have demonstrated the prevention benefits of antiretroviral-based approaches among serodiscordant couples; however, residual transmission observed in recognized serodiscordant couples represents an important and resolvable challenge in HIV prevention.

Young women's views on testing for sexually transmitted infections and HIV as a risk reduction strategy in mutual and choice-restricted relationships

AIM

The aim of this study was to identify relationship dynamics that influences the use of STI/HIV testing among young, urban African American women.

BACKGROUND

Increasing STI/HIV testing is a key prevention strategy, but more research is needed to identify barriers to testing for young women such as intimate partner violence (IPV).

METHODS

Thirty semi-structured interviews were conducted with African American women ages 18-24. Content analysis was used.

RESULTS

Women in choice-restricted relationships were unable to negotiate safer sex practices and testing was viewed as the best option. Women in relationships where the desire to use condoms was mutual used STI and HIV testing as a sign of trust building that preceded unprotected sex.

CONCLUSIONS

STI/HIV testing must be viewed as one strategy within a package of possible risk reduction. For those in choice-restricted relationships, clinicians should screen patients for partner abuse and provide additional support and referrals as clinically appropriate.

Correlates of Sex Trading among Drug-Involved Women in Committed Intimate Relationships: A Risk Profile

BACKGROUND

Despite a slight decline in new human immunodeficiency virus (HIV) infections in New York, marked increases and concentrated epidemics continue among subsets of the population, including women engaged in sex trading. We examined the prevalence and correlates of sex trading among 346 low-income, HIV-negative women in HIV-concordant intimate relationships.

METHODS

Women and their long-term main partners were recruited to participate in an HIV prevention intervention. Baseline data were used in this article.

FINDINGS

Of the 346 women in the study, 28% reported sex trading during the prior 90 days. Multivariate analyses showed increased relative risk of sex trading by lifetime experience of severe intimate partner violence (IPV), drug, and alcohol use, and marginal significance for mental health hospitalization, partner drug dependency, and homelessness.

CONCLUSIONS

These findings suggest an urgent need for HIV prevention and intervention efforts targeted toward women in intimate relationships who trade sex for money or drugs, with an emphasis on IPV, mental health, history of incarceration, and substance abuse.

Importance of Women's Relative Socioeconomic Status within Sexual Relationships in Communication about Safer Sex and HIV/STI Prevention

The socioeconomic status (SES) of women is increasingly considered an important factor for HIV/STI risk. The HIV/STI literature has largely focused on women's absolute levels of SES, and therefore, the importance of their SES relative to their male sexual partners remains understudied. This paper examines the association between women's relative SES and frequency of safer sex communication among heterosexual couples. A convenience sample of 342 couples (N = 684) recruited in New York City was asked about frequency of discussions with their partner about the need to use male condoms, about HIV prevention, and about STI prevention in the previous 90 days. Differences between partners in education, income, employment, housing, and incarceration history were combined using principal component analysis to form an index of women's relative SES. Negative binomial regression models assessed associations between woman's relative SES and communication frequency controlling for age, sex, race, ethnicity, education, and relationship type using a generalized estimating equation framework. On average, participants had 2.5, 4.2, and 4.8 discussions regarding the need to use male condoms, about HIV prevention, and about STI prevention, respectively. A one standard deviation increase in a woman's relative SES score was associated with increased frequency of discussions about male condom use (adjusted rate ratio [aRR], 1.15; 95% confidence interval [CI], 1.03-1.29), about HIV prevention (aRR, 1.25; CI, 1.14-1.37), and about STI prevention (aRR, 1.29; CI, 1.18-1.41). Women's relative SES may be an important factor for sexual communication, and further research on its role in HIV/STI risk may uncover avenues for intervention.

Gender-Specific HIV Prevention Interventions for Women Who Use Alcohol and Other Drugs: The Evolution of the Science and Future Directions

The use of alcohol and other drugs (AODs) is an important driver of gender disparities in HIV prevalence. Consequently, there is a need for women-specific HIV interventions that are conceptualized to address (1) women's risk behavior, their roles in sexual relationships, and gender power dynamics and (2) other issues commonly faced by women who use AODs, such as gender-based violence and victimization. This article presents the evolution of HIV prevention intervention research with women who use AODs. It looks at 3 generations of women-focused HIV research interventions, including first-generation projects that started in the 1990s, second-generation efforts where projects expanded in scope and included adaptions of evidence-based interventions for global relevance, and finally third-generation projects currently underway that combine biobehavioral methods and are being implemented in real-world settings. Because women who use AODs continue to report risk behaviors related to HIV, emphasis should be placed on training scientists to conduct gender-specific studies, increasing funding for new studies, and advocating to ensure that stigma-free services are available for these at-risk women.

Relationship power, communication, and violence among couples: results of a cluster-randomized HIV prevention study in a South African township

Background

Inequitable gender-based power in relationships and intimate partner violence contribute to persistently high rates of HIV infection among South African women. We examined the effects of two group-based HIV prevention interventions that engaged men and their female partners together in a couples intervention (Couples Health CoOp [CHC]) and a gender-separate intervention (Men’s Health CoOp/Women’s Health CoOp [MHC/WHC]) on women’s reports of power, communication, and conflict in relationships.

Methods

The cluster-randomized field experiment included heterosexual couples from a high-density South African township in which neighborhoods were randomized to one of the intervention arms or a control arm that received the WHC only. Participants completed in-person study visits at baseline and 6-month follow-up. We examined group differences using one-way analysis of variance and multivariable regression models.

Results

Of the 290 couples enrolled, 255 women remained in the same partnership over 6 months. Following the intervention, women in the CHC arm compared with those in the WHC arm were more likely to report an increase in relationship control (β=0.92, 95% confidence interval [CI]: 0.02, 1.83, P=0.045) and gender norms supporting female autonomy in relationships (β=0.99, 95% CI: 0.07, 1.91, P=0.035). Women in the MHC/WHC arm were more likely to report increases in relationship equity, relative to those in the CHC arm, and had a higher odds of reporting no victimization during the previous 3 months (MHC/WHC vs WHC: odds ratio =3.05, 95% CI: 1.55, 6.0, P=0.001; CHC vs MHC/WHC: odds ratio =0.38, 95% CI: 0.20, 0.74, P=0.004).

Conclusion

Male partner engagement in either the gender-separate or couples-based interventions led to modest improvements in gender power, adoption of more egalitarian gender norms, and reductions in relationship conflict for females. The aspects of relationship power that improved, however, varied between the couples and gender-separate conditions, highlighting the need for further attention to development of both gender-separate and couples interventions.

Adapting an evidence-based HIV behavioral intervention for South African couples

BACKGROUND

In South Africa, heterosexual couples are at risk for HIV infection and transmission through substance use, gender-based violence and traditional gender roles, and sex risk behaviors such as having multiple partners and unsafe sex.

METHODS

To address these interconnected HIV risks among heterosexual couples, we used the ADAPT framework to modify an existing, efficacious women's HIV prevention intervention (the Western Cape Women's Health CoOp) to include components of an evidence-based couple's intervention from the United States (Project Connect) and components from the Men as Partners program that has been used successfully in South Africa. We conducted focus groups with men, women and couples, and obtained feedback from a long-standing Community Collaborative Board (CCB) to guide the synthesis of elements of these three interventions into a new intervention. We then piloted the adapted intervention for feasibility and acceptability.

RESULTS

The new intervention is called the Couples' Health CoOp. This intervention targets men who use alcohol and other drugs and engage in unprotected sex, and their main female sex partners. The intervention addresses substance use, sex risk, HIV and other sexually transmitted infections, gender roles, gender-based violence, communication skills, and goal-setting activities to increase sexy (eroticize) safe-sex behaviors. The Couples' Health CoOp also includes "voices" from the focus group members to ground the intervention in the experiences of these at-risk couples. In addition, it utilizes a participant handbook that reiterates workshop content and includes homework assignments for couples to complete together to increase problem-solving skills within their relationship, and to improve their sexual relationship and help sustain HIV risk-reduction strategies. All of these adaptations were based on participants' suggestions made during formative work and pilot testing.

CONCLUSIONS

The Couples' Health CoOp is a couple-based HIV prevention intervention that targets alcohol and other drug use to reduce sexual risk, reduce gender-based violence and offer alternatives for conflict resolution, promote healthy relationships, and modify traditional gender roles in South Africa.

Identifying and intervening with substance-using women exposed to intimate partner violence: phenomenology, comorbidities, and integrated approaches within primary care and other agency settings

Substance use and/or disorders (SUDs) have been identified as a significant correlate of intimate partner violence (IPV) exposure and present complex issues that intersect with the topography of IPV, attendant mental health, and physical co-morbidities and may pose barriers to primary care- and other agency-based screening and intervention efforts. Despite substantial research indicating significantly higher rates of all types and severity of IPV victimization among women with SUDs and bidirectional associations between partner or self-use of drugs or alcohol and IPV victimization, effective screening, brief interventions, coordinated systems of care, and treatment approaches to address these co-occurring problems remain very limited. We integrated select research examining the intersection of IPV victimization and SUDs and several comorbidities that have significant public health impact and provided recommendations for scaling up targeted interventions to redress these co-occurring problems among women in primary, emergency, and other care settings.

The Flawed Reliance on Randomized Controlled Trials in Studies of HIV Behavioral Prevention Interventions for People Who Inject Drugs and Other Populations

This article discusses ways in which randomized controlled trials do not accurately measure the impact of HIV behavioral interventions. This is because: 1. Such trials measure the wrong outcomes. Behavior change may have little to do with changes in HIV incidence since behavior change in events between HIV-concordant people have no impact on incidence. Even more important, the comparison of HIV incidence rates between study arms of individual-level RCTs does not measure the true outcome of interest-whether or not the intervention reduces HIV transmission at the community level. This is because this comparison cannot measure the extent to which the intervention stops transmission by HIV-infected people in the study to those outside it. (And this is made even worse if HIV-infected are excluded from the evaluation of the intervention.) 2. There are potential harms implicit in most cognitively oriented behavioral interventions that are not measured in current practice and may not be measurable using RCTs. Intervention trials often reinforce norms and values of individual self-protection. They rarely if ever measure whether doing this reduces community trust, solidarity, cohesion, organization, or activism in ways that might facilitate HIV transmission. 3. Many interventions are not best conceived of as interventions with individuals but rather with networks, cultures of risks, or communities. As such, randomizing individuals leads to effective interventions that diffuse protection through a community; but these are evaluated as ineffective because the changes diffuse to the control arm, which leads to systematic and erroneous reductions in the evaluated effectiveness as RCTs measure it. The paper ends by discussing research designs that are superior to individual-level RCTs at measuring whether an intervention reduces or increases new HIV transmission.

Effects of a couple-based intervention to reduce risks for HIV, HCV, and STIs among drug-involved heterosexual couples in Kazakhstan: a randomized controlled trial

OBJECTIVE

Project Renaissance is a randomized controlled trial of an HIV/hepatitis C virus (HCV)/sexually transmitted infection (STI) prevention intervention conducted in Almaty, Kazakhstan. We hypothesized that couples assigned to the intervention of interest will have lower incidence of HIV, HCV, STIs, rates of unprotected sex, and unsafe injection over the 12-month follow-up period compared with those assigned to an attention control arm.

DESIGN

A total of 300 couples (600 participants) where one or both partners reported injecting drugs in the past 90 days were randomized to 1 of 2 arms: (1) a 5-session HIV/HCV/STI prevention intervention (risk reduction: RR) or (2) a 5-session Wellness Promotion (WP) intervention.

RESULTS

Over the 12-month follow-up period, assignment to RR compared with WP significantly lowered the incidence of HCV infection by 69% [incidence rate ratios (IRR) = 0.31, 95% (CI) confidence interval: 0.10 to 0.90, P = 0.031]. Although differences were not statistically significant, RR participants had a lower incidence of HIV infection by 51% (IRR = 0.49, 95% CI: 0.16 to 1.48, P = 0.204) and any STI by 37% (IRR = 0.63, 95% CI: 0.21 to 1.93, P = 0.418) than WP participants. RR participants reported significantly fewer numbers of unprotected vaginal sex acts with their study partners (IRR = 0.58, 95% CI: 0.36 to 0.93, P = 0.024) and more consistent condom use (odds ratios = 2.30, 95% CI: 1.33 to 4.00, P = 0.003) over the entire follow-up period compared with WP participants.

CONCLUSIONS

Project Renaissance demonstrated a significant effect for biological and behavioral endpoints. Findings draw attention to an HIV/HCV/STI prevention intervention strategy that can be scaled up for drug-involved couples in harm reduction programs, drug treatment, and criminal justice settings.

Systematic review of couple-based HIV intervention and prevention studies: advantages, gaps, and future directions

We conducted a systematic review of couple-based HIV biobehavioral (skills-building, VCT, and adherence) and biomedical (ART, circumcision) prevention and intervention studies designed to reduce sexual- and drug-risk behaviors and HIV transmission and acquisition. Of the 11,162 papers identified in the search, 93 peer-reviewed papers met the inclusion criteria and yielded a total of 33 studies conducted globally. Biobehavioral couple-based prevention and intervention studies have been efficacious in reducing sexual- and drug-risk behaviors, increasing access to HIV testing and care, and improving adherence. Biomedical couple-based studies were found to reduce HIV incidence among HIV-negative sex partners and viral load among HIV-positive partners. Despite much progress, couple-based HIV prevention and intervention studies remain limited; a number of methodological gaps exist and studies focusing on MSM, people who inject drugs, and sex workers are scarce.

Client perspectives on design and implementation of a couples-based intervention to reduce sexual and drug risk behaviors among female sex workers and their noncommercial partners in Tijuana and Ciudad Juárez, México

This mixed-methods study examined the acceptability of a hypothetical couples-based HIV prevention program for female sex workers and their intimate (non-commercial) male partners in Mexico. Among 320 participants, 67 % preferred couples-based over individual programs, particularly among men. Reasons cited for preferring couples-based programs included convenience and health benefits for both partners. Participants reported that they would benefit from general health information and services, HIV counseling and testing, job training (particularly for men) and other services. However, qualitative interviews revealed that barriers relating to the environment (i.e., poor access to services), providers (i.e., lack of a therapeutic alliance), and intimate relationships (i.e., mistrust or instability) would need to be addressed before such a program could be successfully implemented. Despite women's concerns about privacy and men's preferences for gender-specific services, couples-based HIV prevention programs were largely acceptable to female sex workers and their intimate male partners.

People who inject drugs in intimate relationships: it takes two to combat HIV

We reviewed papers published during the past 18 months (2012-2013) focusing on micro-social contexts of gender and power inequalities as drivers of HIV risks among people who inject drugs (PWID) in intimate heterosexual relationships. Although there has been a proliferation of social and behavioral research on the micro-social contexts of drug injection in heterosexual intimate relationships, there is still a gap in knowledge of these issues, particularly in low- and middle-income countries. Research has identified couple-based approaches for PWID in intimate relationships as an effective HIV prevention strategy to address micro-social contexts driving HIV risks. While HIV incidence has declined in many countries, prevalence remains at troubling levels among PWID and transmission from PWID to their sex partners is increasing in many parts of the world. HIV prevention among drug-using couples must address the importance of the relationship dyad and micro-social contexts.

The key role of adherence for the effectiveness of antiretroviral-based prevention: state of the science and implications for the Asia-Pacific region

Remarkable advances have been made in the last few years in biomedical strategies to prevent onward transmission of HIV (treatment as prevention (TasP)) and prevent infection among at-risk populations through pre-exposure prophylaxis (PrEP). Numerous issues remain heavily debated, primarily concerning the feasibility of leveraging resources for both widespread access to antiretroviral therapy (ART) for those living with HIV and access to effective prevention antiretrovirals (ARVs) among those at risk for infection. Even with consistent and wide-spread access to ARVs, the behavioural pathway from ARV access to successful rapid and durable suppression or reaching levels of PrEP adherence that confer high rates of protection is increasingly well recognised. For either 'biobehavioural' strategy to have maximal individual and community benefit, individuals accessing them must actually use them. In this review, the unique and overlapping factors influencing adherence to ART and PrEP are identified, with an emphasis on the behavioural, social and structural facilitators and barriers to TasP and PrEP success. The implications of the current research base and evidence generated specifically within the Asia-Pacific region are discussed.

Dual HIV risk: receptive syringe sharing and unprotected sex among HIV-negative injection drug users in New York City

HIV-negative injection drug users (IDUs) who engage in both receptive syringe sharing and unprotected sex ("dual HIV risk") are at high risk of HIV infection. In a cross-sectional study conducted in New York City in 2009, active IDUs aged ≥18 years were recruited using respondent-driven sampling, interviewed, and tested for HIV. Participants who tested HIV-negative and did not self-report as positive were analyzed (N = 439). Adjusted odds ratios (aOR) and 95 % confidence intervals (95 % CI) were estimated using multinomial logistic regression. The sample was: 77.7 % male; 54.4 % Hispanic, 36.9 % white, and 8.7 % African-American/black. Dual risk was engaged in by 26.2 %, receptive syringe sharing only by 3.2 %, unprotected sex only by 49.4 %, and neither by 21.2 %. Variables independently associated with engaging in dual risk versus neither included Hispanic ethnicity (vs. white) (aOR = 2.0, 95 % CI = 1.0-4.0), married or cohabiting (aOR = 6.3, 95 % CI = 2.5-15.9), homelessness (aOR = 3.4, 95 % CI = 1.6-7.1), ≥2 sex partners (aOR = 8.7, 95 % CI = 4.4-17.3), ≥2 injecting partners (aOR = 2.9, 95 % CI = 1.5-5.8), and using only sterile syringe sources (protective) (aOR = 0.5, 95 % CI = 0.2-0.9). A majority of IDUs engaged in HIV risk behaviors, and a quarter in dual risk. Interventions among IDUs should simultaneously promote the consistent use of sterile syringes and of condoms.

Enhancing acceptability and use of sexual barrier products among HIV concordant and discordant couples

Strategies to prevent HIV transmission may benefit from addressing both individual and dyadic factors. This study compared the impact of group and individual interventions on the acceptability of sexual barrier products among HIV sero-concordant and discordant couples, and evaluated the contribution of couple members' perceived product acceptability to their sexual barrier use. Participants (n = 216 couples) were multicultural couples in Miami, Florida. Longitudinal multilevel modeling and the actor-partner interdependence model were used for analyses. Product acceptability increased more among female group participants, and acceptability of male condoms increased more among sero-discordant couples in the group. Additionally, acceptability of products associated with prevention of STDS/HIV and pregnancy increased more among sero-concordant couples in the group condition. Both actor and partner product acceptability predicted use. Results support the use of group interventions targeting both partners in relationships in prevention programs designed to enhance sexual barrier use.

Can't buy my love: a typology of female sex workers' commercial relationships in the Mexico-U.S. Border Region

Female sex workers (FSWs) experience elevated risk for HIV and sexually transmitted infections (STIs) through unprotected sex with male clients, yet the complexity of these commercial relationships remains understudied. From 2010 to 2011, we explored FSWs' conceptualizations of various client types and related risk behavior patterns using semistructured interviews with 46 FSWs in Tijuana and Ciudad Juarez, Mexico, where FSWs' HIV/STI prevalence is increasing. Our grounded theory analysis identified four types of commercial relationships: nonregular clients, regular clients and friends, clients who "fell in love" with FSWs, and long-term financial providers who often originated from the United States. As commercial relationships developed, clients' social and emotional connections to FSWs increased, rendering condom negotiation and maintaining professional boundaries more difficult. Drug abuse and poverty also influenced behaviors, particularly in Ciudad Juárez, where lucrative U.S. clients were increasingly scarce. While struggling to cultivate dependable relationships in a setting marked by historical sex tourism from a wealthier country, some FSWs ceased negotiating condom use. We discuss the need for HIV/STI research and prevention interventions to recognize the complexity within FSWs' commercial relationships and how behaviors (e.g., condom use) evolve as relationships develop through processes that are influenced by local sociopolitical contexts and binational income inequality.

The potential uses of preexposure prophylaxis for HIV prevention among people who inject drugs

PURPOSE OF REVIEW

Oral preexposure prophylaxis (PrEP) has shown HIV preventive efficacy for several key populations at risk for HIV infection including MSM and heterosexual men and women in HIV serodiscordant relationships. An efficacy trial of daily oral tenofovir among people who inject drugs (IDU) is underway in Thailand.

RECENT FINDINGS

Although efficacy data is pending, there is emerging biological and public health plausibility data suggesting the utility of PrEP as an effective component of combination HIV prevention for IDU. Drawing from studies characterizing adherence to antiretroviral therapy for IDU, there are a range of scientific and operational considerations for the potential use of PrEP for IDU. We review here the available literature on the potential use of PrEP for IDU, barriers to uptake and adherence, and potential implementation science questions, which could address, and potently increase, the effectiveness of this intervention.

SUMMARY

IDU remain the most underserved population in the HIV response worldwide, and have a marked gap in prevention services, making PrEP a potentially promising addition to the prevention toolkit for people who use drugs and, for those already living with HIV infection, for their spouses and other sexual partners.

'Where sex ends and emotions begin': love and HIV risk among female sex workers and their intimate, non-commercial partners along the Mexico-US border

This study explores the affective dimensions of female sex workers' relationships with their intimate, non-commercial partners and assesses how emotions shape each partner's sexual and drug-related risk within their relationship. We draw on qualitative data from a study of HIV, sexually transmitted infections and high-risk behaviours among female sex workers and their non-commercial partners in Tijuana and Ciudad Juárez, Mexico, to illustrate that these couples share relationships based on love, trust, respect and emotional and material support. These relationships range in emotional intensity, which shapes partners' decisions not to use condoms with each other. Drugs were important in most couples' relationships. Among injectors, syringe sharing was common and represented both a sign of care and a pragmatic reaction to conditions of material scarcity. Our findings suggest that couple-based HIV interventions to address dual sexual and drug-related risks should be tailored to the emotional dynamics of sex workers' intimate relationships.

Acceptability of vaginal microbicides among female sex workers and their intimate male partners in two Mexico-US border cities: a mixed methods analysis

Female sex workers (FSWs) may benefit from pre-exposure prophylaxis (PrEP) including microbicides for HIV prevention. Since adherence is a key factor in PrEP efficacy, we explored microbicide acceptability and potential barriers to use within FSWs' intimate relationships in Tijuana and Ciudad Juárez, Mexico, where HIV prevalence is increasing. FSWs and their verified intimate (non-commercial) male partners completed quantitative and qualitative interviews from 2010 to 2012. Our complementary mixed methods design followed an iterative process to assess microbicide acceptability, explore related relationship dynamics and identify factors associated with concern about male partners' anger regarding microbicide use. Among 185 couples (n=370 individuals), interest in microbicides was high. In qualitative interviews with 28 couples, most participants were enthusiastic about microbicides for sex work contexts but some explained that microbicides could imply mistrust/infidelity within their intimate relationships. In the overall sample, nearly one in six participants (16%) worried that male partners would become angry about microbicides, which was associated with higher self-esteem among FSWs and lower self-esteem and past year conflicts causing injury within relationships among men. HIV prevention interventions should consider intimate relationship dynamics posing potential barriers to PrEP acceptability and adherence, involve male partners and promote risk communication skills.

Dual HIV risk and vulnerabilities among women who use or inject drugs: no single prevention strategy is the answer

PURPOSE OF REVIEW

This article examines the dual HIV and sexually transmitted infection (STI) risk behaviors engaged in by women who use or inject drugs; the individual, social, and structural drivers of HIV and STI risk; prevention strategies; and the implications for multilevel, combined, sex-specific HIV prevention strategies.

RECENT FINDINGS

Women who use or inject drugs, especially female sex workers, are at dual risk for HIV, the hepatitic C virus (HCV), and other STIs. In countries with HIV prevalence higher than 20% among injecting drug users (IDUs), female IDUs have slightly higher HIV prevalence than male IDUs. Women who use or inject drugs face multilevel drivers that increase their vulnerabilities to HIV, HCV, and STIs. Despite advances in behavioral HIV prevention strategies for this population, most prevention studies have not sufficiently targeted dyadic, social, and structural levels. Few recent advances in biomedical HIV prevention have focused on women who use drugs and their unique needs.

SUMMARY

HIV prevention strategies and services need to address the unique and multilevel drivers that increase the vulnerabilities to HIV, HCV, and STIs among women who use drugs including those who engage in sex work. Scaling-up and improving access to multilevel and combined HIV prevention strategies for these women is central to combating the HIV epidemic.

Study protocol for the recruitment of female sex workers and their non-commercial partners into couple-based HIV research

Background

Researchers are increasingly recognizing the importance of addressing sexual and drug-related HIV risk within the context of intimate relationships rather than solely focusing on individual behaviors. Practical and effective methods are needed to recruit, screen, and enroll the high risk and hard-to-reach couples who would most benefit from HIV interventions, such as drug-using female sex workers (FSWs) and their intimate, non-commercial partners. This paper outlines a bi-national, multidisciplinary effort to develop and implement a study protocol for research on the social context and epidemiology of HIV, sexually transmitted infections (STI), and high risk behaviors among FSWs and their non-commercial male partners in Tijuana and Ciudad Juarez, Mexico. We provide an overview of our study and specifically focus on the sampling, recruitment, screening, and successful enrollment of high risk couples into a public health study in this context.

Methods/Design

We used targeted and snowball sampling to recruit couples through the female partner first and administered a primary screener to check her initial eligibility. Willing and eligible females then invited their primary male partners for couple-based screening using a couple verification screening (CVS) instrument adapted from previous studies. The CVS rechecked eligibility and separately asked each partner the same questions about their relationship to "test" if the couple was legitimate. We adapted the original protocol to consider issues of gender and power within the local cultural and socioeconomic context and expanded the question pool to create multiple versions of the CVS that were randomly administered to potential couples to determine eligibility and facilitate study enrollment.

Discussion

The protocol successfully enrolled 214 high risk couples into a multi-site public health study. This work suggests the importance of collaborating to construct a study protocol, understanding the local population and context, and drawing on multiple sources of input to determine eligibility and verify the legitimacy of relationships. We provide a practical set of tools that other researchers should find helpful in the study of high risk couples in international settings, with particular relevance to studies of FSWs and their intimate partners.
