RESUMO

Pregnant and lactating persons in sub-Saharan Africa face a heightened risk of HIV acquisition, due to biological and behavioral factors, combined with limited access to prevention and treatment services. Oral pre-exposure prophylaxis (PrEP) and the dapivirine vaginal ring are promising tools for HIV prevention, and the ring's recent approval in multiple African countries represents a significant advancement in expanding access to HIV prevention. In a nested qualitative study within the MTN-042 trial, we explored the acceptability of study products among pregnant persons in the second and early third trimesters. Interviews were conducted privately, using a semi-structured guide with 77 participants, in participants' preferred language. Topics explored included product acceptability (using the theoretical framework of acceptability), user experience, satisfaction, disclosure, community attitudes, and sexual activity during pregnancy. Interview transcripts were analyzed using Dedoose software. We observed positive attitudes among participants towards the study products, which they found generally user-friendly, despite the added complexities of using them during pregnancy. Participants recognized that consistent and correct use would provide protection for both them and their unborn children. Although initial concerns existed, most of these worries dissipated over time, with study staff support and increased product use experience. These findings emphasize the importance of continued surveillance, support, and education to ensure the successful rollout of new HIV prevention measures during pregnancy.

RESUMO

Depression is associated with lower adherence to oral pre-exposure prophylaxis (PrEP) to prevent HIV, but data are not currently available on how depression may affect use of other HIV prevention methods including the dapivirine vaginal ring (DVR). We conducted a mixed methods study using data from the Microbicide Trials Network (MTN) 042/DELIVER (n = 558) and MTN-043/B-PROTECTED (n = 197) studies to describe the prevalence of depressive symptoms and explore how depressive symptoms may have influenced attitudes about use of the monthly DVR and once-daily oral PrEP tablet among pregnant and breastfeeding persons, respectively, in Malawi, South Africa, Uganda, and Zimbabwe. Eleven participants had high Edinburgh Postnatal Depression scores ≥ 10 in MTN-042/DELIVER (2%) and four participants (2%) in MTN-043/B-PROTECTED. In interviews with 9 participants who had high scores (6 DVR, 3 oral PrEP), those with depressive symptoms described overlapping stressors which were magnified by job loss and economic instability during the COVID-19 pandemic, and by experiences of pregnancy/postpartum. These participants experienced a lack of support from partners or family members, and conflict with partners related to trust, and infidelity. While we did not find evidence of a change in product adherence, there was a strong sense of commitment and motivation to use the study products for protection from HIV for participants themselves and their baby. Although lack of social support is usually an obstacle to adherence, in this study, the participants' lives and relationships seemed to have reinforced the need for HIV prevention and motivated women to protect themselves and their babies from HIV.

RESUMO

The Microbicide Trials Network 042 study (MTN-042/DELIVER) is a two-arm, randomized, open-label Phase 3b trial that is evaluating the safety, adherence, and acceptability of the monthly ring and daily oral PrEP among HIV-uninfected pregnant people in four African countries. This analysis focuses on acceptability data captured qualitatively from a subset (n = 48) of the 150 people in the first cohort of the trial who were enrolled in late-stage pregnancy at 36 to 38 weeks gestational age and followed until after delivery. Single IDIs were conducted by trained interviewers at each clinic site using a semi-structured guide. Data excerpts of key codes pertaining to acceptability, pregnancy, and maternal health were summarized, reviewed and interpreted by multinational analyst teams. Although the product use period was relatively short, the data suggested several acceptability findings that may directly translate to longer durations of product use in pregnancy. The first was the overarching maternal sentiment that being able to protect both oneself and their baby was highly valued. The second was the importance of counseling support from providers not only because participants used methods that might generate side effects, but because pregnancy itself is a period with its own set of side effects. The third was that, similar to non-pregnant participants in other trials, here study products were generally liked and described as easy to use. Concerns about ring and oral PrEP use could be addressed with provider counseling and support and should form an essential component rollout among pregnant people.

RESUMO

Introduction: The COVID-19 pandemic greatly impacted HIV prevention and care globally. The pandemic also had disproportionate impacts on the financial, emotional, and physical wellbeing of women and girls in East and Southern Africa, who were already at increased HIV vulnerability. This study aimed to understand how the COVID-19 pandemic and its response efforts impacted the sexual behavior, HIV prevention interest, general healthcare access, and other HIV risk factors of women and girls in HIV prevention studies. Methods: Using the socio-ecological model (SEM), an explanatory sequential mixed-methods analysis was performed with data from four Microbicide Trial Network (MTN) studies on different populations-adolescent girls and young women (AGYW), pregnant persons, breastfeeding persons, and couples-in Malawi, South Africa, Uganda, and Zimbabwe. Descriptive statistics for outcomes of interest were calculated within each study separately and Chi-squared tests of independence were performed to evaluate associations between study population and outcomes. Excerpts from study qualitative interviews were stratified into code reports which were then summarized into memos with key themes and considerations of the SEM framework to provide context to quantitative findings. Results: Few participants (8/731) had known or suspected COVID-19 infection. Sexual frequency and alcohol use decreased most often among AGYW compared to pregnant or breastfeeding women and couples (p-value < 0.001). The pandemic had little impact on changes in reported HIV prevention interest or access to HIV prevention study products. Healthcare access was impacted for everyone, with couples most likely to report decreases in access (p-value < 0.001). From qualitative interviews, economic instability, adverse mental health, and increased violence due to COVID-19 caused increased strain on other factors related to HIV vulnerability. Conclusions: While interest in HIV prevention did not change and a few HIV risks decreased for most women and girls, other vulnerabilities to HIV increased due to the COVID-19 pandemic, highlighting the importance of continued access to HIV prevention for women and girls. More research is needed to better understand the long-term impact of COVID-19 on HIV prevention and vulnerability in community populations.

RESUMO

This study examines qualitative acceptability of the dapivirine vaginal ring (DVR) and oral daily pre-exposure prophylaxis (PrEP) among breastfeeding persons participating in Microbicide Trials Network 043/B-PROTECTED, a phase 3B safety and drug detectability study of DVR and oral PrEP in breastfeeding. A subsample of 52 participants were purposively sampled to participate in an in-depth interview (IDI). Breastfeeding participants found both study products to be acceptable, and easy to use. A common motivation for product use was to protect the baby from HIV, although participants' understanding of how the study drug would work to protect their babies was often unclear. While most participants did not report experiencing side effects, fears about side effects were common as both initial worries about how the study products would affect their health and the health of their baby, and increased anxiety that health issues experienced by them, or their baby were from the products.

RESUMO

Intimate partner violence (IPV) has been associated with poorer mental health outcomes and increased human immunodeficiency virus (HIV) risk behaviors. We examine the relations between IPV, mental health symptomology (defined as psychological distress and alcohol misuse), and engagement in HIV risk behaviors among a sample of South African women who participated in a randomized controlled trial of CHARISMA, an intervention to increase women's agency to use oral pre-exposure prophylaxis (PrEP) safely and consistently as well as mitigate relationship challenges. We also examined the impact of trial participation on women's mental health, as well as the impact of psychological distress on the effectiveness of the CHARISMA intervention. Mental health symptomology and IPV exposure were prevalent and associated with some HIV risk and protective behaviors. Trial participation reduced psychological distress. There was no evidence for mental health symptomology impacting the effectiveness of the CHARISMA intervention.

RESUMO

In South Africa, less than half of children receiving antiretroviral therapy are virally suppressed. Adherence challenges include poor palatability of drugs and high pill burden. Subcutaneous implants offer a long-acting alternative to daily oral dosing regimens, which may improve outcomes in children living with HIV (CLWH). Qualitative in-depth interviews were conducted with 24 health care providers (HCPs) in Johannesburg, South Africa. Interviews were audio-recorded and transcribed. Data were coded and analyzed using NVivo 12 software and a Grounded Theory approach. Most HCPs welcomed an implant option for CLWH. Perceived benefits included fewer clinic visits, improved adherence, and "normalization" of the lives of CLWH. Concerns included painful insertion and removal, the potential for stigmatization, and caregivers' likely rejection of biodegradable implants. A single, small, non-transparent rod with some flexibility was preferred by most participants. HCP training and early outreach to mitigate potential misinformation about implants and caregivers' fears about biodegradable implants were emphasized. Further engagement with caregivers of CLWH is required and ongoing.

RESUMO

HIV acquisition among pregnant and breastfeeding women in sub-Saharan Africa and vertical transmission rates remain high despite established strategies for HIV prevention. During the MTN-041/MAMMA study, we explored the influence of grandmothers (mothers and mothers-in-law of pregnant and breastfeeding women) in eastern and southern Africa on the health-related decisions of pregnant and breastfeeding women and their potential to support use of HIV prevention products. To do this we used structured questionnaires and focus group discussions with three stakeholder groups: 1) grandmothers, 2) HIV-uninfected currently or recently pregnant or breastfeeding women and 3) male partners of currently or recently pregnant or breastfeeding women. A total of 23 focus group discussions comprising 68 grandmothers, 65 pregnant or breastfeeding women and 63 male partners were completed across four study sites. Grandmothers were described as important sources of information during pregnancy and breastfeeding playing both supportive and influencer roles due to personal maternal experience and generational knowledge. While pregnant and breastfeeding women were not keen to involve grandmothers in HIV prevention decision making, they were accepting of grandmothers' involvement in a supportive role. Grandmothers expressed willingness to support pre-exposure prophylaxis use and agreed with the other two stakeholder groups that this decision should be made by women themselves or together with partners. These novel data indicate potential for grandmothers' health related supportive roles to be extended to support decision-making and adherence to biomedical HIV prevention options, and possibly contribute to the decline in HIV acquisition among pregnant and breastfeeding women in these communities.

RESUMO

BACKGROUND: Consistent use of oral pre-exposure prophylaxis (PrEP) has been a challenge among women, particularly when in relationships with lack of partner support or intimate partner violence (IPV). METHODS: We conducted a randomized controlled trial (RCT) of an empowerment counseling intervention called "CHARISMA" delivered to women within a PrEP demonstration project in Johannesburg, South Africa. The trial tested the effectiveness of CHARISMA to increase PrEP adherence; decrease social harms and IPV; and improve partnership dynamics (eg, communication, disclosure and support) compared with those who received the standard of care counselling support and referrals. Four hundred seven HIV-seronegative, nonpregnant women aged 18-45 years were enrolled for 6 months of PrEP use, with 203 randomized (1:1) to the intervention. All participants reporting IPV received counseling and referrals that followed the WHO five-step Listen, Inquire, Validate, Enhance Safety, and Support approach. RESULTS: This RCT did not identify statistically significant differences between study arms for PrEP adherence or relationship dynamics, with the exception of an increase in PrEP disclosure among intervention arm women. In our study, we cannot determine whether the lack of detectable findings may have been because of lack of intervention effect, strength of standard of care services, low risk in the study population, or other factors. CONCLUSIONS: Addressing IPV and relationship dynamics remain important factors influencing HIV risk, and addressing these within the context of PrEP delivery is an important synergistic opportunity. CHARISMA was highly acceptable to participants, and further adaptation and testing of the intervention to other populations and settings will augment the evidence base.

RESUMO

Women account for a disproportionate percentage of new HIV infections in sub-Saharan Africa indicating a need for female-initiated HIV prevention options congruent with their lifestyles. The dapivirine vaginal ring for HIV prevention is one such option. We explored the interest of women, who used this ring during the Microbicide Trials Network's ASPIRE and HOPE studies, in using the ring post-licensure and what they perceived as important considerations for future use. We also explored perspectives of HOPE participants' male partners on their involvement in their partners' future ring use. Women appeared keen to use the ring in the future and expressed desires for easy access, support for both ongoing and new users and intense community engagement. In parallel, male partners indicated high levels of interest in supporting their partners' ring use and being involved in ring use decision making. These data offer important insights for ring rollout planning and engagement activities.

RESUMO

Biomedical, female-initiated HIV prevention methods can help reduce disproportionately high HIV rates among women in sub-Saharan Africa, but male partner resistance and intimate partner violence (IPV) may impact ability to ensure effective use. To support consistent use of the dapivirine vaginal ring (VR), we pilot-tested the impact of the CHARISMA relationship counseling intervention ("CHARISMA") with women enrolled in the multi-site open-label Microbicide Trials Network (MTN) 025/HOPE trial at the Wits Reproductive Health and HIV Research Institute (Wits RHI) site in Johannesburg, South Africa. Lay counselors used a 42-item tool with five subscales to assess relationships and IPV and provide tailored counseling at enrolment, followed by a booster counselling session at Month 1 and follow-up checks at Months 3 and 6. We evaluated potential impact by examining self-reported ring disclosure to partners, partner clinic attendance, self-reported incident social harms (SH) and IPV, and biomarkers of ring adherence at Wits RHI. We subsequently compared these outcomes at three comparator HOPE study sites using multivariable regression models. Comparator study sites were purposively selected as those most similar to Wits RHI for baseline characteristics identified a priori. At Wits RHI, 95 of 96 (99%) HOPE participants enrolled into the CHARISMA pilot study. Mean age was 30, 36.8% lived with a partner, and 85.3% received their partner's financial support. During the six months of pilot study follow-up, participants reported: ring use disclosure to partners at 72.7% visits; 4.3% partners attending the research clinic; one partner-related SH; and 9.5% experienced incident IPV. The mean level of dapivirine released from returned used rings was 3.4 mg (SD 1.56), suggesting moderate adherence. Participants in the CHARISMA pilot had high background prevalence and incidence of IPV but were nevertheless able to adhere to ring use, and some male partners came to the research clinic. In adjusted regression models, compared to Wits RHI, partner clinic attendance was lower at all comparator sites; and significantly so at Site A (aRR 0.12, 95% CI 0.00-0.98). Sites B and C had lower levels of dapivirine released (suggesting lower adherence), but this difference was not significant. Site B women were more likely to report ring disclosure to partners at FU visits (aRR 1.12, 95% CI 1.00-1.25). IPV reported during follow-up was significantly lower at Site B (aRR 0.20, 95% CI 0.04-0.98, p = 0.047). CHARISMA taught women skills to decide on levels of ring-use disclosure to partners or others; therefore it is difficult to interpret differences in ring disclosure to partners with other sites. Similarly, CHARISMA heightened participants' awareness of abuse, possibly increasing IPV reports. Testing CHARISMA under fully-powered controlled conditions will improve understanding of its impact on women's relationships and ability to use female-initiated HIV prevention methods.

RESUMO

As demonstrated by the Phase III clinical trial, MTN-020/ASPIRE, the monthly dapivirine vaginal ring is well tolerated and reduces the risk of HIV-1 as a woman-initiated prevention option. This analysis uses data from the follow-on MTN-032/Assessment of ASPIRE and HOPE Adherence (AHA) qualitative study to understand how perceptions (or misperceptions) of ring efficacy may have influenced behavior during ASPIRE, and affected intention to use the ring in future ring projects, specifically HOPE, the planned open-label extension study. Single in-depth interviews (n = 98) and 12 focus group discussions (n = 89) were conducted with women at seven sites in Malawi, South Africa, Uganda and Zimbabwe. Eligibility included participation in the ASPIRE active arm, and ring use for ≥ 3 months or at least 1 month if seroconversion occurred. Interviews were audio-recorded, transcribed into English, coded in Dedoose and thematically analyzed. Demographic and behavioral questionnaire data were summarized in Stata. Most AHA participants perceived the ring to be effective, and described simply trusting it or having confidence in it because they, or other participants in risky situations, remained HIV-uninfected. Participants described ring efficacy after receiving ASPIRE results as a binary assessment: the ring worked or not. Many did not remember exact efficacy percentages because of lack of comprehension or memory but recalled key details about age differences. The majority expressed interest in future ring use. There is a need to investigate improved ways of explaining placebo-controlled trials and efficacy to women in Sub-Saharan Africa. Now that ring efficacy, is known, these benefits must be well communicated, and understood by end-users and key stakeholders. Engagement with end-users to construct effective messages and to develop tools to measure understanding of partial efficacy will be essential.

RESUMO

INTRODUCTION: The CHARISMA intervention, nested within the MTN-025/HOPE vaginal ring trial in Johannesburg, South Africa, seeks to facilitate women's use of HIV prevention products by promoting partner dialogue and mitigating intimate partner violence (IPV). We developed "HEART", a lay counselor-administered relationship assessment tool, for the CHARISMA pilot. The five-scale tool assesses participants' endorsement of Traditional Values (TV), her HIV Prevention Readiness (HPR) and levels of partner support (PS), abuse and control (PAC), and resistance to HIV prevention (PR), guiding decisions about which of three counselling modules to offer (partner communication/A; ring disclosure/B; and IPV prevention/C). METHODS: We correlated baseline scores on HEART subscales with a) independent measures of relationship stability, disclosure and IPV to assess construct validity, and b) with specific modules offered to determine how HEART was used in the pilot. We examined changes in HEART scores at three and six months. Finally, we ran separate growth models for each subscale to examine changes in scores, accounting for partnership changes and counseling module(s) received. RESULTS: Baseline HEART scores correlated as predicted among subscales and with other measures. Reliabilities for four subscales were 0.75 or higher. Women who disclosed study participation and ring use scored higher on PS and lower on PR. Women experiencing IPV scored lower on PS, and higher on PAC and PR. During the pilot, 82% of women received one and 17% received two or more modules; over half received the IPV module. Women with higher PAC and PR scores were more likely to receive the IPV than the communication or disclosure modules. Over time, the TV, PAC and PR scores decreased, and PS score increased. Receiving the IPV module was associated with a decreased PAC score. CONCLUSIONS: These data offer preliminary evidence for HEART construct and predictive validity and support its further evaluation to guide implementation and monitor the impact of the CHARISMA intervention in a randomized controlled evaluation.

RESUMO

Globally, HIV affects women disproportionally to men, particularly in sub-Saharan Africa. While the monthly dapivirine vaginal ring (VR) is a promising female-initiated HIV prevention method, it is important to understand how well the ring is liked. With former participants of HOPE, an open-label extension trial of the ring, we used emoji stickers and a worksheet to explore female end-user's acceptability of and opinions about the VR. We aimed to understand these participants' opinions about the VR, and how they had changed over time, particularly in the context of known efficacy of the dapivirine VR. Most participants easily understood the exercise and how to use the emoji stickers, with a few exceptions. For those who had trouble understanding how to use the emoji, interviewer support and encouragement helped them to understand and continue with the exercise. Emoji interpretation varied widely with participants using the same emoji to express divergent opinions. Using the emoji stickers, participants expressed mostly positive opinions of the vaginal ring for HIV prevention, with some lingering concerns about the product's partial effectiveness. This paper contributes to the literature supporting the assertion that the dapivirine VR for HIV prevention is acceptable to women, and that acceptability increases with time and proper education. This analysis also provides evidence that emoji visual tools can enhance understanding of acceptability of an intervention when used in qualitative research.

RESUMO

BACKGROUND: Women may need or seek male partner approval to safely and consistently use oral antiretroviral pre-exposure prophylaxis (PrEP) or vaginal microbicides. We developed CHARISMA, a counseling intervention to support women's relationships and their ability to consistently use HIV prevention products. METHODS: In a pilot study with 95 female participants in Johannesburg, South Africa, lay counselors implemented CHARISMA, assessing participants' relationship(s) with their male partner(s) and barriers or facilitators to HIV prevention method use, and then providing tailored, interactive counseling. We conducted study participant surveys and clinic staff interviews to evaluate CHARISMA's feasibility and acceptability. RESULTS: The CHARISMA pilot study indicates that a two-session relationship counseling intervention with 6-month follow-up to support women's ability to safely and effectively use vaginal microbicides was generally acceptable and feasible. Most participants thought CHARISMA was relevant, helpful, and about the right length, and that it had a positive impact on their relationships with their partners and their product use. Staff estimated that the intervention took 1.5-2 h to implement at enrollment and 45 min to an hour for the month 1 visit. They thought that overall CHARISMA was generally feasible to implement. CONCLUSIONS: Findings from this study suggest several lessons learned that may be relevant to others developing interventions supporting women's use of oral PrEP or vaginal microbicides. The use of lay counselors instead of nurses to deliver counseling appeared to be successful, but the counselors experienced significant stress from hearing about participants' traumatic experiences and required emotional support to avoid burnout. Although staff and participants felt that having multiple intervention sessions over time was valuable, a similar level of intensity may not be feasible in other settings. Further research is needed to determine an intervention delivery mode and follow-up period that optimally balances participant needs and clinic resources. Male engagement was a challenge, as it has been in previous studies of vaginal microbicides. Alternative strategies to reach men that do not require them to come to the clinic or rely on their female partners may be more effective.

RESUMO

Female-initiated HIV prevention methods, such as oral pre-exposure prophylaxis (PrEP) and the vaginal ring, may be important risk reduction strategies for breastfeeding women. Given their novelty, information about the sociocultural context and how it influences perceptions of and support for their use during breastfeeding is lacking. To address this gap, we conducted 23 focus group discussions separately with pregnant and breastfeeding women, male partners and grandmothers (N = 196) and 36 in-depth interviews with key informants in Malawi, South Africa, Uganda and Zimbabwe. We analysed the data using a framework analysis method. Overall, breastfeeding was the norm, and participants described the transference of health (e.g., nutrition) and disease (e.g., HIV) to children through breast milk. Participants considered the early breastfeeding period as one of high HIV transmission risk for women. They explained that male partners tend to seek outside sexual partners during this period because women need time to recover from delivery, women focus their attention on the child, and some men are disgusted by breast milk. Participants highlighted concerns about the drugs in oral PrEP transferring to the child through breast milk, but fewer worried about the effects of the vaginal ring because the drug is localized. Women, grandmothers and key informants were supportive of women using these HIV prevention methods during breastfeeding, while male partners had mixed opinions. These findings can be used to tailor messages for promoting the use of PrEP or the vaginal ring during breastfeeding in sub-Saharan Africa.

RESUMO

In HIV prevention trials, male partners have influenced women's ability to adhere to investigational products, including antiretroviral (ARV) containing vaginal rings. Validated scales can be useful tools to systematically measure complex constructs, such as those related to male partner engagement. Although multiple scales exist to assess physical, psychological and sexual violence within intimate relationships, fewer scales focus on supportive behaviors within these relationships. Our intervention involved development of a Healthy Relationship Assessment Tool (HEART) that assessed both positive and negative aspects of male partner involvement in women's HIV prevention. We identified and refined 127 potential items, representing intimate partner violence, agency and social support. A structured survey, including potential items and other sociodemographic and behavioral variables was administered to former microbicide trial and non-trial participants. We conducted an exploratory factor analysis (EFA) to identify a reduced set of constructs and items to screen women who might experience social harms or benefits from vaginal ring use. We examined associations between constructs and with other survey variables to assess content and construct validity. In a subset of 10 women who participated in the survey and qualitative interviews, we used qualitative data to predict survey scores. We retained five constructs with theoretical relevance and good-to-strong reliability for the tool, including: Traditional Values; Partner Support; Partner Abuse & Control; Partner Resistance to HIV Prevention; and HIV Prevention Readiness. Predicted associations between HEART constructs, and correspondence between participants' qualitative data and HEART scores were generally correct, while those between constructs and other sociodemographic variables were more mixed. Initial validation of the HEART tool was promising. The tool will be used during the CHARISMA pilot study at the Johannesburg MTN 025/HOPE site and validated as part of a randomized controlled trial of CHARISMA within a PrEP demonstration project. Beyond clinical trial settings, HEART could assist PrEP or antiretroviral treatment (ART) providers with an easy-to-administer tool to identify risk and tailor risk reduction, empowerment and adherence counseling for microbicides, PrEP or ART related services.

RESUMO

This article describes the development of the Community Health clinic model for Agency in Relationships and Safer Microbicide Adherence intervention (CHARISMA), an intervention designed to address the ways in which gender norms and power differentials within relationships affect women's ability to safely and consistently use HIV pre-exposure prophylaxis (PrEP). CHARISMA development involved three main activities: (1) a literature review to identify appropriate evidence-based relationship dynamic scales and interventions; (2) the analysis of primary and secondary data collected from completed PrEP studies, surveys and cognitive interviews with PrEP-experienced and naïve women, and in-depth interviews with former vaginal ring trial participants and male partners; and (3) the conduct of workshops to test and refine key intervention activities prior to pilot testing. These steps are described along with the final clinic and community-based intervention, which was tested for feasibility, acceptability, and preliminary effectiveness in Johannesburg, South Africa.

RESUMO

Despite being designed for autonomous use, research suggests partner approval is often in women's microbicide use. Microbicide study participants have described many ways product use affects relationships, from improving sexual pleasure to increasing harm, including exacerbating intimate partner violence (IPV). As the dapivirine ring proceeds closer to licensure, supporting women's agency to use microbicides safely is a priority. We conducted 42 in-depth interviews with former participants of the Microbicide Trials Network (MTN)-020 trial of the dapivirine vaginal ring and their male partners in Johannesburg, South Africa, to explore how ring use and partnership dynamics interacted. We sampled women who reported harms or partner non-support and women with supportive partners. Male and female narratives revealed high background levels of IPV. Women described how study participation/ring use exacerbated violence, and for a few couples served as a rationale for additional abuse. In response, women described feeling powerless and fearful of conflict, resulting in product nonuse. For one participant violence was reduced, and for several others, empowerment was sparked. These findings suggest future providers have the opportunity to shift more women from a place of fear/violence to one of safety/empowerment through the integration of IPV screening and relationship counselling.

RESUMO

Female-initiated methods of HIV prevention are needed to address barriers to HIV prevention rooted in gender inequalities. Understanding the sociocultural context of pre-exposure prophylaxis (PrEP) trials, including gender-based violence, is thus critical. MTN-003C (VOICE-C), a qualitative sub-study of the larger MTN-003 (VOICE) trial, examined sociocultural barriers and facilitators to PrEP amongst women in Johannesburg. We conducted focus-group discussions, in-depth interviews and ethnographic interviews with 102 trial participants, 22 male partners, 17 community advisory board members and 23 community stakeholders. We analysed how discussions of rape are emblematic of the gendered context in which HIV risk occurs. Rape emerged spontaneously in half of discussions with community advisory board members, two-thirds with stakeholders and among one-fifth of interviews/discussions with trial participants. Rape was used to reframe HIV risk as external to women's or partner's behaviour and to justify the importance of PrEP. Our research illustrates how women, in contexts of high levels of sexual violence, may use existing gender inequalities to negotiate PrEP use. This suggests that future interventions should simultaneously address harmful gender attitudes, as well as equip women with alternative means to negotiate product use, in order to more effectively empower women to protect themselves from HIV.
