Multifaceted Barriers to Rapid Roll-out of HIV Pre-exposure Prophylaxis in China: A Qualitative Study Among Men Who Have Sex with Men.

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) as a safe and effective antiretroviral medicine-based prevention against HIV has not been widely adopted by gay, bisexual, and other men who have sex with men (MSM) in China. A deeper understanding of barriers and facilitators to PrEP uptake is needed to inform the development of effective interventions. METHOD: During July-August 2020, we conducted one-on-one semi-structured interviews with 31 Chinese MSM with varied PrEP use experiences (PrEP-naïve, former, and current PrEP users). Interviews were digitally recorded and transcribed in Chinese. Informed by the Information-Motivation-Behavioral Skills Model (IMB), we analyzed the data using a thematic analysis approach to identify the barriers and facilitators to PrEP uptake among Chinese MSM. RESULTS: Major barriers to PrEP uptake among MSM in the sample included uncertainty about PrEP efficacy and lack of PrEP education (information), concerns over potential side effects and cost (motivation), and difficulties in identifying authentic PrEP medications and managing PrEP care (behavioral skills). Facilitators include the perceived benefit of PrEP in improving the quality of sex life and control over health. At the contextual level, we also identified barriers to PrEP access from a thriving informal PrEP market and stressors related to being MSM. CONCLUSION: Our findings identified a need to invest in non-discriminatory public health messaging of PrEP, explore options for MSM-friendly provision of PrEP outside of traditional HIV care settings, and be attentive to the unique context of an established informal PrEP market in future PrEP initiatives.

An instant messaging mobile phone application for promoting HIV pre-exposure prophylaxis uptake among Chinese gay, bisexual and other men who have sex with men: A mixed methods feasibility and piloting randomized controlled trial study.

BACKGROUND: Mobile health (mHealth) is a promising intervention mode for HIV prevention, but little is known about its feasibility and effects in promoting pre-exposure prophylaxis (PrEP) uptake among Chinese gay, bisexual and other men who have sex with men (GBMSM). METHODS: We evaluated an instant messaging application using a WeChat-based mini-app to promote PrEP uptake among GBMSM via a mixed-methods design that includes a 12-week, two-arm randomized controlled pilot trial and in-depth progress interviews in Guangzhou, China. Primary outcomes include the number of PrEP initiations, individual-level psychosocial variables related to PrEP initiation, and usability of the PrEP mini-app. RESULTS: Between November 2020 and April 2021, 70 GBMSM were successfully enrolled and randomized into two arms at 2:1 ratio (46 to the intervention arm, 24 to the control arm). By the end of 12-week follow-up, 22 (31.4%) participants completed the initial consultation and lab tests for PrEP, and 13 (18.6%) filled their initial PrEP prescription. We observed modest but non-significant improvements in participants' intention to use PrEP, actual PrEP initiation, PrEP-related self-efficacy, stigma, and attitudes over 12 weeks when comparing the mini-app and the control arms. Qualitative interviews revealed the key barriers to PrEP uptake include anticipated stigma and discrimination in clinical settings, burden of PrEP care, and limited operating hours of the PrEP clinic. In-person clinic navigation support was highly valued. CONCLUSIONS: This pilot trial of a mobile phone-based PrEP mini-app demonstrated feasibility and identified limitations in facilitating PrEP uptake among Chinese GBMSM. Future improvements may include diversifying the content presentation in engaging media formats, adding user engagement features, and providing off-line in-clinic navigation support during initial PrEP visit. More efforts are needed to understand optimal strategies to identify and implement alternative PrEP provision models especially in highly stigmatized settings with diverse needs. TRIAL REGISTRATION: Trial registration: The study was prospectively registered on clinicaltrials.gov (NCT04426656) on 11 June, 2020.

Reaching Out-of-school Adolescent Girls and Young Women at Risk for HIV Through Their Social Networks.

Out-of-school adolescent girls/young women (AGYW) in Africa are at increased risk for HIV and are underserved by HIV prevention interventions. Identifying social networks of out-of-school AGYW may be a strategic approach for reaching them. A sequential mixed methods study design was used. The PLACE (Priorities for Local AIDS Control Efforts) methodology, implemented in one ward of Dar es Salaam, Tanzania, identified 69 networks of AGYW. We randomly selected 28 networks and conducted surveys and network assessments with 80.9% (n = 310) of the members. On average, the networks consisted of 13.7 members, and had a density of 0.65 and a transitivity of 0.80, indicating high cohesion. The networks were mostly female (92%). On average, 67% of network membership were AGYW aged 15-24 years, of whom 70% were out-of-school and 67% were sexually active. Among sexually active AGYW aged 15-24, self-reported HIV seropositivity was 12.2%. We then conducted focus group discussions with 6 purposively selected networks. AGYW described their networks as sources of support and advice. Social norms supported AGYW engaging in transactional sex to alleviate life's hardships; it was the easiest way to earn income without "sweating". AGYW discussed IPV as a common experience, and social norms stigmatized AGYWs' use of condoms. AGYW were largely unaware of pre-exposure prophylaxis. The self-reported HIV prevalence rates of this cohort were higher than national averages, suggesting we tapped into high-risk networks. Social norms promoted transactional and unprotected sex. Social networks are an acceptable channel for HIV prevention intervention delivery to out-of-school AGYW.

Male partners' support and influence on pregnant women's oral PrEP use and adherence in Malawi.

Introduction: Daily oral pre-exposure prophylaxis (PrEP) is a safe and effective HIV prevention method for pregnant and postpartum women, but adherence barriers exist. Understanding the role of male partners in supporting PrEP use may inform strategies to support PrEP adherence among pregnant and breastfeeding women. Methods: To understand male partners' involvement in women's use of PrEP, we conducted in-depth interviews with pregnant women in Lilongwe, Malawi who had recently decided to use PrEP (n = 30) and their male partners (n = 20) in the context of a PrEP adherence trial. Women were purposively recruited to ensure variation in their partners' HIV status. Interviews were conducted in Chichewa using a semistructured guide. We followed a thematic approach to analyze the interview data. Results: Most male partners were receptive to women using PrEP during pregnancy because it eased their fears of the woman and baby acquiring HIV. Men often played a key role in women's PrEP adherence by providing daily reminders and encouragement to adhere to their medication. The majority of women appreciated this support from the men as it lessened the burden of remembering to take their medications daily on their own and aided their adherence. However, several women who lacked male partner support spoke of wanting their partners to be more involved. Many men living with HIV found the mutual support beneficial for their antiretroviral therapy adherence, while men without HIV or with status unknown appreciated knowing that the family was protected. While most men were open to women continuing PrEP beyond the current study, some would only support it if women were still at risk for acquiring HIV. Conclusion: In this study, male partners were strongly motivated to support the PrEP adherence of their female partners as a way of ensuring that the pregnant women and unborn babies were protected against HIV. Promoting disclosure and tangible support that arises organically among men may be helpful, but programs to enhance this support and identify ways to support women who do not receive support from their partners or do not wish to disclose their PrEP use to partners may be needed.

Perspectives and experiences of Zambian pregnant and postpartum women receiving two intervention models to increase uptake of male partner HIV testing.

This study explored the experiences of pregnant women who received two intervention models for increasing uptake of male partner HIV testing in antenatal settings. As part of a randomised trial, we interviewed twenty participants who received partner notification services only while 22 received the partner notification plus HIV self-testing. Thematic analysis was used to analyse the data. Partner notification services helped to initiate discussions of HIV testing with partners, influence partners to undergo testing, and encouraged disclosure of HIV status. Some women experienced difficulties engaging partners due to fear of their partner's reaction. Some partners were unable to test due to time constraints. The partner notification plus HIV self-testing intervention, stimulated discussion about HIV testing; facilitated testing for men at their convenience; addressed privacy/confidentiality, and stigma concerns; and provided the opportunity to disclose HIV status. Some women feared disclosure and retribution in case of discordance results. There were also challenges with men making follow-ups for confirmatory HIV tests. The addition of HIV self-test kits to partner notification services can expand HIV testing services to male partners, including those of HIV-negative women. Additional efforts are needed to link men to appropriate HIV prevention, care, and treatment services.

Development and implementation of a process evaluation for intervention quality improvement of a community-based behavioral HIV intervention trial in Tanzania.

Aim: Process evaluations for social and behavioral interventions are increasingly important as interventions become more complex and multi-faceted. Conducting process evaluations in low-resource international settings can be challenging. Process evaluations in low-resource international settings can help inform and improve quality of ongoing intervention implementation. We conducted a process evaluation of a cluster-randomized controlled trial to assess the efficacy of a microfinance and health leadership program on sexually transmitted infections and intimate partner violence perpetration among young men in Tanzania. Subject and Methods: Our trial included 1,491 participants and the intervention lasted two years. We collected process data on microfinance loan uptake and repayment, and health leaders' health conversations with peers to monitor intervention reach and dose received. We developed a database system that allowed offline data collection and synced to a central database when internet was accessible. Research staff in the U.S. accessed data from the central database to analyze and create regular implementation reports. Results: Process graphical reports facilitated identification of implementation challenges and enabled us to resolve issues before they worsened. For example, from a group with low microfinance loan repayment we learned area participants perceived the loan to be a grant, and then we clarified the misinformation with participants. Conclusions: The process evaluation helped inform ongoing intervention implementation, including approaches to improve reach and uptake of interventions. Field staff time was protected by systemizing the sharing of data processing and analyses across the global team.

Combination HIV prevention during pregnancy and the post-partum period in Malawi and Zambia: a mathematical modelling analysis.

INTRODUCTION: Despite widespread success in reducing vertical HIV transmission, most antenatal care (ANC) programmes in eastern and southern Africa have not emphasized primary prevention of maternal HIV acquisition during pregnancy and lactation/breastfeeding. We hypothesized that combination HIV prevention interventions initiated alongside ANC could substantially reduce maternal HIV incidence. METHODS: We constructed a multi-state model describing male-to-female HIV transmission in steady heterosexual partnerships during pregnancy and lactation/breastfeeding, with initial conditions based on population distribution estimates for Malawi and Zambia in 2020. We modelled individual and joint increases in three HIV prevention strategies at or soon after ANC initiation: (1) HIV testing of male partners, resulting in HIV diagnosis and less condomless sex among those with previously undiagnosed HIV; (2) initiation (or re-initiation) of suppressive antiretroviral therapy (ART) for male partners with diagnosed but unsuppressed HIV; and (3) adherent pre-exposure prophylaxis (PrEP) for HIV-negative female ANC patients with HIV-diagnosed or unknown-status male partners. We estimated the percentage of within-couple, male-to-female HIV transmissions that could be averted during pregnancy and lactation/breastfeeding with these strategies, relative to base-case conditions in which 45% of undiagnosed male partners become newly HIV diagnosed via testing, 75% of male partners with diagnosed but unsuppressed HIV initiate/re-initiate ART and 0% of female ANC patients start PrEP. RESULTS: Increasing uptake of any single strategy by 20 percentage points above base-case levels averted 10%-11% of maternal HIV acquisitions during pregnancy and lactation/breastfeeding in the model. Joint uptake increases of 20 percentage points in two interventions averted an estimated 19%-23% of transmissions, and with a 20-percentage-point increase in uptake of all three interventions, 29% were averted. Strategies achieving 95% male testing, 90% male ART initiation/re-initiation and 40% female PrEP use reduced incident infections by 45%. CONCLUSIONS: Combination HIV prevention strategies provided alongside ANC and sustained through the post-partum period could substantially reduce maternal HIV incidence during pregnancy and lactation/breastfeeding in eastern and southern Africa.

Mechanisms to enhance racial equity in health care: Developing a model to facilitate translation of the ACCURE intervention.

Background: As medical and public health professional organizations call on researchers and policy makers to address structural racism in health care, guidance on evidence-based interventions to enhance health care equity is needed. The most promising organizational change interventions to reduce racial health disparities use multilevel approaches and are tailored to specific settings. This study examines the Accountability for Cancer Care through Undoing Racism and Equity (ACCURE) intervention, which changed systems of care at two U.S. cancer centers and eliminated the Black-White racial disparity in treatment completion among patients with early-stage breast and lung cancer. Purpose: We aimed to document key characteristics of ACCURE to facilitate translation of the intervention in other care settings. Methods: We conducted semi-structured interviews with participants who were involved in the design and implementation of ACCURE and analyzed their responses to identify the intervention's mechanisms of change and key components. Results: Study participants (n = 18) described transparency and accountability as mechanisms of change that were operationalized through ACCURE's key components. Intervention components were designed to enhance either institutional transparency (e.g., a data system that facilitated real-time reporting of quality metrics disaggregated by patient race) or accountability of the care system to community values and patient needs for minimally biased, tailored communication and support (e.g., nurse navigators with training in antiracism and proactive care protocols). Conclusions: The antiracism principles transparency and accountability may be effective change mechanisms in equity-focused health services interventions. The model presented in this study can guide future research aiming to adapt ACCURE and evaluate the intervention's implementation and effectiveness in new settings and patient populations.

Intimate partner violence victimization during pregnancy increases risk of postpartum depression among urban adolescent mothers in South Africa.

BACKGROUND: It is estimated that 38.8% of mothers develop postpartum depression (PPD) in South Africa. While empirical evidence documents an association between intimate partner violence (IPV) victimization in pregnancy and PPD among adult women, the association has been underexamined among adolescent mothers (< 19 years). The study's purpose is to examine whether IPV victimization during pregnancy is associated with PPD among adolescent mothers. METHODS: Adolescent mothers (14-19 years) were recruited at a regional hospital's maternity ward in KwaZulu Natal, South Africa between July 2017-April 2018. Participants completed behavioral assessments at two visits (n = 90): baseline (up to 4 weeks postpartum) and follow-up (6-9 weeks postpartum, when PPD is typically assessed). The WHO modified conflict tactics scale was used to create a binary measure of any physical and/or psychological IPV victimization that occurred during pregnancy. Participants with scores ≥ 13 on the Edinburgh Postpartum Depression Scale (EPDS) were classified as having symptoms of PPD. We used a modified Poisson regression with robust standard errors to assess PPD in association with IPV victimization during pregnancy, controlling for relevant covariates. RESULTS: Nearly one-half (47%) of adolescent mothers reported symptoms of PPD by 6-9 weeks post-delivery. Further, IPV victimization during pregnancy was highly prevalent (40%). Adolescent mothers who reported IPV victimization during pregnancy had marginally higher risk of PPD at follow-up (RR: 1.50, 95 CI: 0.97-2.31; p = 0.07). The association was strengthened and significant in covariate-adjusted analysis (RR: 1.62, 95 CI: 1.06-2.49; p = 0.03). CONCLUSIONS: Poor mental health was common among adolescent mothers, and IPV victimization during pregnancy was associated with PPD risk among adolescent mothers. Implementing IPV and PPD routine screenings during the perinatal period may aid in identifying adolescent mothers for IPV and PPD interventions and treatment. With the high prevalence of IPV and PPD in this vulnerable population and the potential negative impact on maternal and infant outcomes, interventions to reduce IPV and PPD are needed to improve adolescent mothers' well-being and their baby's health.

BACKGROUND: More than one-third of adult mothers experience postpartum depression (PPD) in South Africa and intimate partner violence (IPV) victimization is a strong risk factor of PPD for adult mothers. However, there are no studies on adolescent mothers that look at the link between IPV victimization and PPD. This paper aims to examine whether IPV victimization during pregnancy is associated with PPD among adolescent South African mothers. METHODS: We had 90 adolescent mothers (aged 14­19 years old) complete an initial survey between delivery and 4 weeks postpartum to collect information on IPV during their pregnancy. Participants completed an additional survey between 6 and 9 week postpartum to collect information on the symptoms of PPD. RESULTS: Nearly one-half (47%) of adolescent mothers reported symptoms of PPD by 6­9 weeks post-delivery. Report of IPV victimization during pregnancy was also very high (40%). Adolescent mothers who experienced IPV victimization during pregnancy were more likely to report symptoms of PPD between 6 and 9 weeks postpartum. CONCLUSIONS: PPD and IPV was very common in our sample, and IPV victimization during pregnancy was linked to PPD among adolescent mothers. Having routine screenings during pregnancy and postpartum period can identify adolescent mothers IPV and PPD interventions and treatment. With the high reports of IPV and PPD in this sample and the potential negative impact on maternal and infant outcomes, interventions to reduce IPV and PPD are needed to improve adolescent mothers' well-being and their baby's health.

Private sector antimalarial sales a decade after "test and treat": A cross-sectional study of drug shop clients in rural Uganda.

Background: The World Health Organization has promoted "test and treat" guidelines for malaria since 2010, recommending all suspected malaria cases be confirmed with a parasitological test, typically a rapid diagnostic test (RDT), prior to treatment with antimalarial medications. However, many fevers at private drug shops in Uganda continue to be treated presumptively as malaria without diagnostic testing. Methods: The purpose of this study was to document private sector malaria case management in rural Uganda through a cross-sectional survey of drug shop clients in Bugoye sub-county. Drug shop vendors (n = 46) recorded information about sales interactions with clients reporting fever or requesting antimalarials and collected capillary blood samples from clients who purchased medications without an RDT. We estimated the proportion of clients who purchased an RDT, adhered to the RDT result, and received antimalarials without having laboratory-confirmed malaria. Results: Most drug shops were unlicensed (96%) and sold RDTs (98%). Of 934 clients with suspected malaria who visited study drug shops during the data collection period, only 25% bought an RDT. Since some clients reported previous RDTs from the public sector, 40% of clients were aware of their malaria status at the drug shop. Among those with negative tests, 36% still purchased antimalarials. Sixty-five percent of clients who purchased an antimalarial without an RDT subsequently tested negative. Conclusions: Despite national guidelines, drug shop clients who purchase antimalarials from drug shops in Bugoye are often not tested to confirm a malaria diagnosis prior to treatment. Most clients treated presumptively with antimalarials did not have malaria. Interventions are needed to improve malaria case management and rational drug use in the private sector.

Relationships Between Stigma and Intimate Partner Violence Among Female Sex Workers Living With HIV: Social and Economic Exclusion.

Violence against female sex workers (FSWs) perpetrated by their intimate (i.e., non-commercial) partners, particularly against FSWs living with HIV, is understudied. Stigma can deplete the economic resources, social relationships, and mental well-being of stigmatized people, which may increase their intimate partner violence (IPV) risk. We quantitatively assessed relationships between HIV stigma and sex work stigma and IPV victimization among FSWs living with HIV in the Dominican Republic (n = 266). Enacted HIV stigma, in the form of job loss, and anticipated HIV stigma, in the form of fear of exclusion by family, were associated with increased IPV risk. Potential association mechanisms, including increased economic vulnerability and social isolation, and programmatic responses are discussed.

Understanding PrEP decision making among pregnant women in Lilongwe, Malawi: A mixed-methods study.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is a promising tool for HIV prevention during pregnancy. With increasing rollout in antenatal settings, counselling strategies to help pregnant women make appropriate decisions about PrEP use are needed. Understanding women's motivations and concerns for PrEP use-and how these inform their decision making and feelings about the decision to start PrEP-are critical to inform these strategies. METHODS: We conducted a convergent mixed-methods study from June 2020 to June 2021 in the context of a PrEP adherence support trial among HIV-negative pregnant women in Lilongwe, Malawi. Two hundred women completed a survey reporting their motivations and concerns about PrEP use, and their feelings about the decision to start PrEP (Decisional Regret Scale). Thirty women completed in-depth interviews to better understand the decision-making process, including motivations and concerns weighed in women's decision to use PrEP. Analyses comprised descriptive and bivariate statistics, thematic qualitative analysis, and integration of quantitative and qualitative results. RESULTS: Women initiating PrEP during pregnancy were highly motivated to obtain HIV protection for themselves and their unborn child, often due to perceived HIV risk connoted by a recent sexually transmitted infection and/or concerns about partner non-monogamy. These motivations prevailed despite some concerns about safety and side effects, anticipated stigmatization, and concerns about adherence burden and pill attributes. Many women had informed their partner of their decision to use PrEP yet few felt their decision was contingent upon partner approval. Most women felt positively about the decision to start PrEP (mean decisional regret = 1.2 out of 5), but those with a greater number of concerns reported greater decisional regret (B = 0.036; p = 0.005). Furthermore, women who were specifically concerned about partner disclosure, who disliked pills or who had no perceived HIV risk reported greater decisional regret. CONCLUSIONS: Pregnant women were strongly motivated by the promise of HIV protection offered by PrEP and accepted it despite diverse concerns. A shared decision-making approach that centres pregnant women and offers partner involvement may help identify and address initial concerns about PrEP use and support prevention-effective use of PrEP during this important period.

Adoption of HIV pre-exposure prophylaxis among women at high risk of HIV infection in Kenya.

In 2017, Kenya became one of the first African countries to provide pre-exposure prophylaxis (PrEP) in its national HIV prevention plan. We sought to characterize factors associated with PrEP uptake and persistence among a cohort of women at risk of HIV infection during the early stages of PrEP scale-up in Kenya. HIV-negative women ≥18 years with ≥2 sexual partners in the past 4 weeks were recruited as part of an ongoing cluster randomized trial of an HIV self-testing intervention. PrEP use was assessed at baseline and at 6- and 12-month follow-up visits. Between June 2017 and August 2018, 2,086 were enrolled and had complete baseline data. 138 (6.6%) reported PrEP use during the first year of the study. Although PrEP use increased, persistence on PrEP was low, and less than half of individuals reported continuing PrEP at follow-up visits. In multivariate analyses, PrEP use was associated with recent STIs, having an HIV-positive primary partner, having regular transactional sex in the past 12 months, and being a female sex worker. In the early stages of PrEP scale-up in Kenya, uptake increased modestly among women with risk factors for HIV infection, but overall uptake and persistence was low.

Intimate Partner Violence and Contraception among Adolescent Girls and Young Women: A Longitudinal Analysis of the Girl Power-Malawi Cohort.

PURPOSE: In sub-Saharan Africa, sexually active adolescent girls and young women (AGYW) experience high rates of intimate partner violence (IPV) and low levels of contraceptive use, but the effect of IPV on contraceptive use is not well understood. METHODS: In the Girl Power-Malawi study, AGYW aged 15-24 were recruited from 4 health centers in Lilongwe, Malawi, and followed for 1 year. At baseline, AGYW were assessed for IPV using the modified Conflict Tactics Scale. AGYW reported contraceptive method use at 6 and 12 months, characterized as barrier, non-barrier, or any modern method. Modified Poisson regression was implemented to estimate risk ratios (RRs) and 95% confidence intervals (CIs) to examine the effect of IPV on contraceptive use. RESULTS: One thousand AGYW were enrolled, and 954 non-pregnant participants were included. Baseline prevalence of IPV with the most recent partner was 35.5% (physical), 46.2% (sexual), and 76.9% (emotional). Baseline IPV did not affect contraceptive use at 6 months (aRR [95% CI]: physical 0.98 [0.91-1.05]; sexual 1.00 [0.94-1.07]; emotional 1.03 [0.94-1.12]) or 12 months (physical 0.95 [0.89-1.02]; sexual 0.96 [0.90-1.02]; emotional 0.98 [0.91-1.05]). None of the 3 IPV categories affected contraceptive use when the outcome was restricted to either barrier or non-barrier methods. CONCLUSIONS: In this cohort, IPV was not a key driver of contraceptive use in longitudinal analyses. Interventions are needed to address the alarming rates of IPV in this population, but addressing IPV alone might be insufficient to address low contraceptive use, and multifaceted youth-friendly health services might be necessary.

'When I have these kits I have confidence' - HIV self-testing provides agency for women in their sexual decision-making.

Oral fluid-based HIV self-testing (HIVST) has emerged as a promising approach to increasing HIV testing coverage, particularly among high-risk populations. Understanding the experiences of women using self-tests and offering them to their sexual partners (secondary distribution) is crucial for determining the potential of HIVST. Qualitative in-depth interviews were conducted among 32 women at high risk of HIV infection, including women who engage in transactional sex, who participated in a cluster randomised trial of a secondary distribution strategy in western Kenya. Interviews explored how women used self-tests within relationships and how this affected their sexual decision-making. Three key themes emerged: women used HIVST to assess risk prior to engaging in sex with partners; HIVST provided women with increased agency to engage in or end relationships; and women appreciated these benefits and urged expanded access to self-tests. HIVST has the potential to support HIV prevention objectives in settings with high prevalence of HIV.Trial registration: ClinicalTrials.gov identifier: NCT03135067.

Intimate partner violence perpetration and sexual risk behaviour: Identifying shared determinants among young men in Tanzania.

In this study we examined factors that predict involvement in different patterns of sexual risk behavior and IPV perpetration among young men in Tanzania (n = 979), with a focus on identifying factors that distinguish men who engage in both behaviours from those who do not. Risk factors were drawn from three domains thought to be upstream drivers of both IPV and sexual risk: poverty, adverse childhood experiences, and inequitable gender norms. A three-step latent class analysis was used to assess whether and how factors from each domain distinguished subgroups of men whose behaviour patterns were characterised as comorbid (involvement in IPV and sexual risk behaviour), IPV-only, sexual risk only, and normative (low risk). Consistent with expectations, greater food insecurity, adverse childhood experiences, and inequitable gender norms related to violence and sexual behaviour predicted increased risk of membership in the comorbid group compared to other sub-groups. Findings support the promise of integrated prevention programmes targeting the common causes of IPV perpetration and sexual risk behaviour.

Examining Why Age-Disparate Relationships Influence Unsafe Sex Postpartum Among South African Women: Relationship Control and Physical Partner Violence as Explanatory Mechanisms.

HIV incidence rates in South Africa are extremely high, particularly postpartum. However, there is limited knowledge of women's HIV risk behavior postpartum. Women in age-disparate relationships may be less able to negotiate safe sex postpartum than women whose partners are similar ages because they have less relationship power. The study's purpose is to test whether being in an age-disparate relationship predicts postpartum unsafe sex and to explore relationship control and intimate partner violence (IPV) as explanatory mechanisms. Data are obtained from 516 HIV-negative participants who completed a survey during pregnancy and at 14 weeks postpartum as part of a longitudinal study in Durban. Age variables, relationship control, and IPV during pregnancy were included in a multivariate model predicting unsafe sex postpartum. We also assessed whether the hypothesized mediators explained the association between being in an age-disparate relationship and unsafe sex postpartum by using indirect effect analysis with bootstrapping. Women's mean age was 24.34 years (range = 18.03-45.36); the mean difference in ages in relationships was 3.19 years (range = -6.1 to 30.1). More than a quarter reported unsafe sex postpartum (27%). Age-disparate relationship, lower relationship control, and higher IPV were each longitudinally associated with unsafe sex. Relationship control, but not IPV, mediated the association between age-disparate relationship and unsafe sex (indirect effect [B] = 0.01, 95% confidence interval [CI] = [0.0002, 0.0283]). Age disparity, relationship control, and IPV all contributed to unsafe sex postpartum. Interventions that reduce the formation of age-disparate relationships and increase women's relationship power in pregnancy are needed to reduce women's HIV risk in the postpartum period.

A mixed-methods study of resilience and return to school among adolescent mothers in South Africa.

ABSTRACTUp to two-thirds of South African adolescent mothers drop out of school, which increases their HIV risk and other poor health outcomes. Despite variability in adolescent mothers' schooling trajectories, we have a limited understanding of their re-enrollment in school following the life-changing circumstance of childbirth. In this paper, we draw on qualitative interviews (n = 16) and quantitative surveys (n = 109) with adolescent mothers (aged 14-19) who had recently given birth to describe how access to individual and social resources contributes to their resilience following childbirth and thus affects their ability to re-enroll in school. Nearly all the adolescent mothers in our study expressed a desire to return to school, and most of their families also emotionally supported adolescent mothers in these goals. Despite mothers' high hopes and familial emotional support, only half of the adolescent mothers re-enrolled in the first six months following childbirth. Adolescent mothers' re-entry trajectories were strongly affected by institutional support and by family members' provision of instrumental support. To a lesser extent, support from partners and peers also played a role in re-enrollment. Multilevel interventions to maximise resilience following the onset of early motherhood may facilitate return to school and positively influence adolescent mothers' health and well-being.

Individual and Relationship-Level Correlates of Transactional Sex Among Adolescent Girls and Young Women in Malawi: A Multilevel Analysis.

Transactional sex increases HIV risk among adolescent girls and young women (AGYW). Understanding the individual and dyadic nature of transactional sex may provide evidence for risk reduction interventions. Multilevel logistic regression was used to cross-sectionally examine correlates of transactional sex among AGYW in Lilongwe, Malawi. Participants (N = 920) reported 1227 relationships. Individual-level associations were found between being divorced/widowed (AOR 5.07, 95% CI 1.93, 13.25), married (AOR 0.26, 95% CI 0.09, 0.72), or unstably housed (AOR 7.11, 95% CI 2.74, 18.47) and transactional sex. At the relationship-level, transactional sex occurred in relationships with: non-primary primary partners (AOR 4.06, 95% CI 2.37, 6.94), perceived partner concurrency (AOR 1.85, 95% CI 1.11, 3.08), and feared violence with couples HIV testing (AOR 2.81, 95% CI 1.26, 6.29), and less likely to occur in relationships with children (AOR 0.15, 95% CI 0.06, 0.38). Multiple co-occurring social and structural vulnerabilities increase transactional sex engagement warranting the need for social protection and gender transformative approaches.

The Intersection of Intimate Partner Violence Perpetration and Sexual Risk Behavior Among Young Men in Tanzania: A Latent Class Analysis of Patterns and Outcomes.

Few studies of intimate partner violence (IPV) perpetration and sexual risk behavior among men have examined how multiple dimensions of these behaviors intersect in ways that may uniquely elevate health risks. The current study used latent class analysis to: (1) identify distinct patterns of IPV and sexual risk behavior in a sample of Tanzanian men (n = 985) and (2) examine associations between identified patterns and health outcomes. Four classes were identified: normative (64% of the sample), IPV only (14%), sexual risk only (13%), and comorbid IPV/sexual risk (5%). Compared to men in the normative subgroup, men in the comorbid group had significantly higher odds of STI infection, higher perceived HIV risk, and greater odds of substance use. Findings provide evidence that engaging in IPV and multiple sexual partnerships (i.e., a comorbid pattern) denotes elevated health risks across a range of indicators, suggesting the importance of targeted treatment and prevention efforts for men in this subgroup.

RESUMEN: Pocos estudios sobre la violencia infligida por la pareja (IPV) y las conductas sexuales de riesgo entre los hombres han examinado como las múltiples dimensiones de estas conductas pueden combinarse para elevar los riesgos de estas conductas para la salud. El estudio actual utilizó el análisis de clases latentes para: (1) identificar patrones (o clases) distintos de IPV y conductas sexuales de riesgo en una muestra de hombres de Tanzania (n = 985) y (2) examinar asociaciones entre los patrones identificados y indicadores de salud. Se identificaron cuatro clases: normativa (64% de la muestra), IPV solo (14%), riesgo sexual solo (13%) y riesgo sexual / IPV comórbido (5%). En comparación con los hombres del subgrupo normativo, los hombres del grupo comórbido tenían probabilidades significativamente más altas de infección de transmisión sexual, mayor riesgo percibido de VIH, y mayores probabilidades de consumo de sustancias (alcohol y marijuana). Los hallazgos proporcionan evidencia de que ser perpetrador de violencia en pareja y tener múltiples parejas sexuales (un patrón comórbido) es asociado con múltiples riesgos para la salud, lo que sugiere la importancia del tratamiento dirigido y los esfuerzos de prevención para los hombres en este subgrupo.
