Abstract
BACKGROUND Adolescent girls and young women (AGYW), aged 15-24 years, are disproportionately affected by HIV and other sexual and reproductive health (SRH) risks due to varying social, cultural, and economic factors that affect their choices and shape their knowledge, understanding, and practices with regard to their health. Socio-Behavioral Change Communication (SBCC) interventions targeted at strengthening the capabilities of individuals and their networks have supported the demand and uptake of prevention services and participation in biomedical research. However, despite growing global recognition of the domain, high-quality evidence on the effectiveness of SBCC remains scattered. This evidence and gap map (EGM) report characterizes the evidence base on SBCC interventions for strengthening HIV Prevention and Research among AGYW in low- and middle-income countries (LMICs), identifying evidence gaps and outlining the scope of future research and program design. OBJECTIVES The objectives of the proposed EGM are to: (a) identify and map existing EGMs in the use of diverse SBCC strategies to strengthen the adoption of HIV prevention measures and participation in research among AGYW in LMICs and (b) identify areas where more interventions and evidence are needed to inform the design of future SBCC strategies and programs for AGYW engagement in HIV prevention and research. METHODS This EGM is based on a comprehensive search of systematic reviews and impact evaluations corresponding to a range of interventions and outcomes-aimed at engaging AGYW in HIV prevention and research - that were published in LMICs from January 2000 to April 2021. Based on guidance for producing a Campbell Collaboration EGM, the intervention and outcome framework was designed in consultation with a group of experts. These interventions were categorized across four broad intervention themes: mass-media, community-based, interpersonal, and Information Communication and Technology (ICT)/Digital Media-based interventions. They were further sub-categorized into 15 intervention categories. Included studies looked at 23 unique behavioral and health outcomes such as knowledge attitude and skills, relationship dynamics, household dynamics, health care services, and health outcomes and research engagement. The EGM is presented as a matrix in which the rows are intervention categories/sub-categories, and the columns are outcome domains/subdomains. Each cell is mapped to an intervention targeted at outcomes. Additional filters like region, country, study design, age group, funding agency, influencers, population group, publication status, study confidence, setting, and year of publication have been added. SELECTION CRITERIA To be eligible, studies must have tested the effectiveness of SBCC interventions at engaging AGYW in LMICs in HIV prevention and research. The study sample must have consisted of AGYW between the ages of 15-24, as defined by UNAIDS. Both experimental (random assignment) and quasi-experimental studies that included a comparison group were eligible. Relevant outcomes included those at the individual, influencer, and institutional levels, along with those targeting research engagement and prevention-related outcomes. RESULTS This EGM comprises 415 impact evaluations and 43 systematic reviews. Interventions like peer-led interactions, counseling, and community dialogues were the most dominant intervention sub-types. Despite increased digital penetration use of media and technology-driven interventions are relatively less studied. Most of the interventions were delivered by peers, health care providers, and educators, largely in school-based settings, and in many cases are part of sex-education curricula. Evidence across geographies was mostly concentrated in Sub-Saharan Africa (70%). Most measured outcomes focused on disease-related knowledge dissemination and enhancing awareness of available prevention options/strategies. These included messaging around consistent condom use, limiting sexual partners, routine testing, and awareness. Very few studies were able to include psychographic, social, and contextual factors influencing AGYW health behaviors and decisions, especially those measuring the impact of social and gender norms, relationship dynamics, and household dynamics-related outcomes. Outcomes related to engagement in the research were least studied. CONCLUSION This EGM highlights that evidence is heavily concentrated within the awareness-intent spectrum of behavior change and gets lean for outcomes situated within the intent-action and the action-habit formation spectrum of the behavior change continuum. Most of the evidence was concentrated on increasing awareness, knowledge, and building risk perception around SRH domains, however, fewer studies focused on strengthening the agency and self-efficacy of individuals. Similarly, evidence on extrinsic factors-such as strengthening social and community norms, relationships, and household dynamics-that determine individual thought and action such as negotiation and life skills were also found to be less populated. Few studies explore the effectiveness of these interventions across diverse AGYW identities, like pregnant women and new mothers, sex workers, and people living with HIV, leading to limited understanding of the use of these interventions across multiple user segments including key influencers such as young men, partners, families, religious leaders, and community elders was relatively low. There is a need for better quality evidence that accounts for the diversity of experiences within these populations to understand what interventions work, for whom, and toward what outcome. Further, the evidence for use of digital and mass-media tools remains poorly populated. Given the increasing penetration of these tools and growing media literacy on one end, with widening gender-based gaps on the other, it is imperative to gather more high-quality evidence on their effectiveness. Timely evidence generation can help leverage these platforms appropriately and enable intervention designs that are responsive to changing communication ecologies of AGYW. SBCC can play a critical role in helping researchers meaningfully engage and collaborate with communities as equal stakeholders, however, this remains poorly evidenced and calls for investigation and investment.

Abstract
A substantial proportion of heterosexually acquired HIV infections in the U.S. occur between partners in primary relationships characterized by mixed HIV status. The U.S. Centers for Disease Control and Prevention have issued guidelines prioritizing HIV-serodifferent couples for primary HIV prevention, including treatment-as-prevention and pre-exposure prophylaxis (PrEP). Yet, very little research has been conducted to understand the perspectives and practices of HIV-serodifferent couples regarding HIV prevention strategies in the U.S. To help fill this gap, we conducted a mixed methods study with 27 mostly Black/African American and Latinx HIV-serodifferent heterosexual couples residing in New York City to explore their knowledge, attitudes, practices, and perspectives regarding combination HIV prevention, including condoms, PrEP and viral control. All couples expressed the desire to maintain viral suppression in the HIV-positive partner, which was not always achieved. There was considerable heterogeneity in the use of HIV prevention methods by couples; and several patterns emerged that were largely driven by gender and relationship dynamics. Female partners, in particular, expressed high levels of anxiety around transmission of HIV and thus desired multiple methods of protection. Healthcare providers should consider couples' psychosocial well-being, relationship quality, and other motivational factors when helping to tailor HIV preventative care for mixed-status couples.

Abstract
Objective This study aimed to explore lived experience and risk reduction behaviors among sero-negative, discordant male partners living with HIV-positive women in Addis Ababa, Ethiopia, 2019. Methods A phenomenological study was conducted to explore lived experience and risk reduction behaviors. The study participants were purposively selected 13 sero-negative male partners living with HIV-positive women. An in-depth interview was used to explore important information. A semi-structured interview guide was used to execute the in-depth interview. The in-depth interview was analyzed thematically through the support of ATLAS-ti 7 software. Results Scientific explanation of discordant result is not well understood rather, it is associated with religious, cultural, natural resistance, and passive carrier explanations. Sero-negative partners faced several challenges and lived dilemmatic life related to partner mood or behavioral change, maintaining the marital relationship, the desire of child, psychosocial, sexual life, and lack of support system. Risk reduction behaviors like condom use, safe sex practice, preventing sexually transmitted infection, avoiding substance use, continuous checkup and follow-up were not well reflected in their lived experience and were poorly understood. Personalized use of sharp materials to avoid blood contact and support of a partner in the proper use of ART drugs were positively reported risk reduction behaviors. Conclusion Sero-negative partners need special attention just as HIV-positive partners in couples with the discordant result. Life suffering is not limited to HIV-positive partners, rather sero-negative partners also faced several challenges and dilemmatic life. HIV transmission risk reduction behavior is not well established and understood.

Abstract
BACKGROUND Heterosexual couples contribute to most new HIV infections in areas of generalized HIV epidemics in sub-Saharan Africa. After Couples' Voluntary HIV Counseling and Testing (CVCT), heterosexual concordant HIV negative couples (CNC) in cohabiting unions contribute to approximately 47% of residual new infections in couples. These infections are attributed to concurrent sexual partners, a key driver of the HIV epidemic in Zambia. METHODS/DESIGN Ten Zambian government clinics in two of the largest cities were randomized in matched pairs to a Strengthening Our Vows (SOV) intervention or a Good Health Package (GHP) comparison arm. SOV addressed preventing HIV infection from concurrent partners and protecting spouses after exposures outside the relationship. GHP focused on handwashing; water chlorination; household deworming; and screening for hypertension, diabetes and schistosomiasis. CNC were referred from CVCT services in government clinics. Follow-up includes post-intervention questionnaires and outcome assessments through 60 months. Longitudinal outcomes of interest include self-report and laboratory markers of condomless sex with outside partners and reported sexual agreements. We present baseline characteristics and factors associated with study arm and reported risk using descriptive statistics. RESULTS The mean age of men was 32 and 26 for women. On average, couples cohabited for 6 years and had 2 children. Baseline analyses demonstrated some failures of randomization by study arm which will be considered in future primary analyses of longitudinal data. An HIV/STI risk factor composite was not different in the two study arms. Almost one-quarter of couples had an HIV risk factor at baseline. DISCUSSION In preparation for future biomedical and behavioral interventions in sub-Saharan Africa, it is critical to understand and decrease HIV risk within CNC.

Abstract
Objectives: To evaluate the frequency of HIV serodiscordants couples and their seronegative partners who were candidates for pre-exposure prophylaxis (PrPE), and the knowledge about behavioural measures to reduce virus transmission. Methods: The research was performed in Northeastern Brazil, from February 2016 to March 2017. Ninety HIV-positive individuals (Index) and their HIV-serodiscordant partners (n = 17) were submitted for epidemiological, clinical, and laboratory questionnaires, and for rapid laboratory tests for syphilis, hepatitis B and C. Results: High frequencies of HIV-syphilis (34.4%) and HIV-HBV (3.3%) coinfection were detected in the HIV-positive individuals. Three new HIV cases were detected in partners. Most participants in both groups (85.6%, Index; 94.1%, Partners) had an excellent degree of knowledge regarding HIV transmission, although nine seronegative HIV partners with a high risk of HIV infection were identified (53%). HIV-positive individuals had a high frequency of HIV-syphilis co-infection and 10% of them did not use antiretroviral by personal option. Conclusions: Adoption of PrEP and other preventive measures to prevent HIV transmission in serodiscordants couples should be studied and evaluated.

Abstract
Lack of condom use by married or cohabiting couples in populations with high rates of HIV infection has become a significant public health issue. This study investigated whether an HIV risk-reduction intervention (RRI) would increase condom use when delivered to serodiscordant couples as a unit. Of the 62 couples that were screened, 30 serodiscordant couples were enrolled in the study, and randomized 2:1 to an immediate intervention-waitlist control study. The 12-week intervention focused on communication, problem-solving, and negotiation skills. Participants were assessed at baseline, three and six months after the intervention. The main outcome measures were consistent condom use, HIV seroconversion and fidelity to the programme. The use of condoms increased for both the intervention and control groups after receiving a 12-week RRI. Group comparisons showed a significant difference at three months, with a significantly higher mean proportion of condom-protected sex acts (p = 0.0119) between the control and intervention groups, the later showing an increase in condom use. No seroconversion was detected, and the overall retention rate of participants was 83.33%. Counselling heterosexual couples as a unit prompted an increase in condom use, but sustained condom use remains a challenge.

Abstract
INTRODUCTION Global efforts to end HIV by 2030 focus on reducing and eventually eliminating new infections in priority populations. Identifying these populations and characterizing their vulnerability factors helps in guiding investment of scarce HIV prevention resources to achieve maximum impact. We sought to establish HIV prevalence, spatial distribution and risk factors for HIV infection in the Kenyan fishing communities of Lake Victoria. METHODS We conducted a cross-sectional survey of 2637 people from all the 308 fish-landing beaches on the Kenyan shore of Lake Victoria. The number of participants enrolled at each beach were weighted based on the size of the beach, determined by the number of functional registered boats. We used simple random sampling to select those to be approached for study participation. Consenting participants were privately interviewed about their socio-economic and demographic characteristics and sexual behavior, and were invited for HIV test using the Kenya rapid HIV testing protocol. We used descriptive statistics and multivariate logistic and linear regression for analysis. RESULTS We found high HIV prevalence of 32% with significant differences between men (29%) and women (38%). Among men, having an HIV negative sexual partner, being circumcised, increasing number of condom protected sex acts in the preceding month, being younger and being a resident of Homa Bay, Kisumu, Siaya and Busia counties compared to Migori County reduced the risk of HIV infection. For women, being married, having more children with the current spouse, having an HIV negative sexual partner and being a resident of Busia compared to Migori County reduced the risk of HIV infection. We also found that longer distance from the beaches to the nearest public health facilities was associated with increasing cumulative HIV prevalence at the beaches. CONCLUSION Fishing communities have high HIV prevalence and may greatly benefit from interventions such as wider ART coverage, couple HIV risk reduction counseling, PrEP use for HIV negative partner at substantial continuous risk, alongside other HIV prevention services that the Kenyan government is currently rolling out. This will additionally require adequate plans to synchronize the provision of these services with the population's routine schedules for all these options to be reasonably accessible to them.

Abstract
BACKGROUND Sexual transmission of HIV frequently occurs in the context of a primary relationship between two partners; however, HIV prevention interventions generally focus on individuals at risk, rather than specifying couples as a unit of change and analysis, neglecting the crucial role that partners may play in sexual behaviour. This article reviews published scientific literature addressing couple-oriented HIV counselling and testing and other behavioural interventions using an online search for peer-reviewed papers. METHODS A systematic review was conducted to evaluate what has been published on psychosocial interventions in HIV serodiscordant couples in Africa. Electronic databases were searched from January 1990 to December 2015. Quality assessment of included studies was conducted using the Systematic Appraisal of Quality in Observational Research tool. RESULTS The electronic database searches initially retrieved 493 records; after cross-referencing, removing duplicates and applying strict inclusion and exclusion criteria, only eight papers were included in this review. All the studies under review showed that couples-focused counselling and educational programmes were associated with positive outcomes including reduced HIV transmission, reduced unprotected sex, increased rates of status disclosure and high levels of treatment adherence. CONCLUSIONS The literature on interventions for HIV serodiscordant couples is sparse. However, most interventions indicate that couples-focused interventions are effective in HIV risk reduction. In spite of the limited available data and repeated recommendations by different health authorities, couple-centred approaches to HIV prevention have not been implemented on a large scale.

Abstract
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.

Abstract
We conducted a prospective cohort study to evaluate intimate partner violence (IPV) as a risk factor for detectable plasma viral load in HIV-positive female sex workers (FSWs) on antiretroviral therapy (ART) in Kenya. IPV in the past year was defined as ≥1 act of physical, sexual, or emotional violence by the index partner (i.e. boyfriend/husband). The primary outcome was detectable viral load (≥180 copies/ml). In-depth interviews and focus groups were included to contextualize results. Analyses included 195 women (570 visits). Unexpectedly, IPV was associated with significantly lower risk of detectable viral load (adjusted relative risk 0.21, 95 % CI 0.05-0.84, p-value = 0.02). Qualitative findings revealed that women valued emotional and financial support from index partners, despite IPV. IPV was not a major barrier to ART adherence. The observed association between IPV and lower risk of detectable viral load in FSWs may be due to unmeasured personal and relationship factors, warranting further research.

Abstract
Pre-exposure prophylaxis (PrEP) for HIV-uninfected persons is highly efficacious for HIV prevention. Understanding how people at risk for HIV will use PrEP is important to inform PrEP scale-up and implementation. We used qualitative methods to gather insights into couples' early experiences with PrEP use within the Partners Demonstration Project, an open-label implementation study evaluating integrated delivery of PrEP and antiretroviral therapy (ART). PrEP is offered to HIV uninfected partners until the HIV-infected partner initiates and sustains ART use (i.e., PrEP as a "bridge" to ART initiation and viral suppression). From August 2013 to March 2014 we conducted 20 in-depth dyadic interviews (n = 40) with heterosexual HIV serodiscordant couples participating at the Thika, Kenya study site, exploring how couples make decisions about using PrEP for HIV prevention. We developed and applied deductive and inductive codes to identify key themes related to experiences of PrEP initiation and use of time-limited PrEP. Couples reported that PrEP offered them an additional strategy to reduce the risk of HIV transmission, meet their fertility desires, and cope with HIV serodiscordance. Remaining HIV negative at follow-up visits reinforced couples' decisions and motivated continued adherence to PrEP. In addition, confidence in their provider's advice and client-friendly services were critical to their decisions to initiate and continue use of PrEP. Strategies for wide-scale PrEP delivery for HIV serodiscordant couples in low resource settings may include building capacity of health providers to counsel on PrEP adoption while addressing couples' concerns and barriers to adoption and continued use.

Abstract
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.

Abstract
This qualitative study aims to gain in-depth information about the attitudes of HIV-serodiscordant couples towards two new methods of HIV prevention; Pre-Exposure Prophylaxis and Treatment as Prevention, both of which have been recently recommended by the World Health Organisation. Semi-structured interviews were conducted with 38 individuals in a serodiscordant relationship in Western Kenya. Topic guides were used to elicit information on perceived benefits, concerns, and preferences towards Treatment as Prevention and Pre-Exposure Prophylaxis. Data evaluation and thematic generation were developed using framework analysis. Results suggest that the majority of participants, irrespective of gender and HIV status, found Treatment as Prevention the more acceptable strategy. Key factors influencing this decision were HIV-negative participants' limited motivation to take prophylactic antiretrovirals and the likely health improvements Treatment as Prevention offers HIV-positive partners. However, issues were raised concerning the likelihood of low concurrent condom use and poor medication adherence when using these preventative approaches. It was concluded that the adoption of Treatment as Prevention as a method of HIV control in Kenya is likely to be more readily accepted by serodiscordant couples than Pre-exposure Prophylaxis. However, future implementation of either strategy would require measures to address the possibility of risk compensation and poor adherence.

Abstract
Data on risky sexual behaviors in people living with HIV/AIDS (PLWHA) is still scarce in some populations around the world. The purpose of this study was to assess the factors associated with the use of condoms in a representative sample of PLWHA in outpatient treatment in the city of São Paulo. Six hundred and sixty-seven HIV-positive patients (383 men and 284 women) who were being treated at eight centers participated in this study. Data were collected using a sociodemographic survey, the Beck depression and anxiety inventories, a survey of alcohol and other drugs use, the Alcohol Use Disorders Identification Test, a sexual behavior survey, and the Sexual Risk Behavior Assessment Schedule. The majority of study participants were sexually active (almost 62% of the sample had at least one sexual partner in the last three months), and at least one-fourth engaged in unsafe sex (25.3% did not use condoms during at least one instance of anal and/or vaginal intercourse in the past three months). Multivariate logistic regression showed that engaging in unprotected sex was more likely among females (p < .001), persons with an HIV-positive partner (p < .001), and people using cannabis before sex (p = .002). These findings should stimulate health-care workers to create specific groups for women, seroconcordant couples, and cannabis users to discuss condom use, as they seem to be vulnerable groups.
