Item The impact of conditional cash transfers for HIV prevention on peer relationships: perspectives from female recipients and non‑recipients in HPTN 068(2022) Makhosazane Nomhle Ndimande‑Khoza; Fiona Scorgie; Sinead Delany‑Moretlwe; Amanda Selin; Rhian Twine; Kathleen Kahn; Audrey Pettifor; Catherine MacPhailCCTs are currently being explored for HIV prevention among adolescent girls and young women (AGYW) in South‑ ern Africa. However, little is known about how CCT geared towards adolescents’ infuence peer relationships, despite evidence that peer relationships form a critical part of development in adolescence. This article presents fndings from a qualitative study that explored CCT recipients’ and non-recipients’ perspectives on the impact of CCTs paid to AGYW on peer relationships. HPTN 068 was a randomised controlled trial that assessed whether providing CCT to AGYW and their households reduces AGYW’s risk of acquiring HIV. As part of this trial, we conducted interviews and focus group discussions with sub-samples of AGYW (n=39), who were both cash recipients and non-recipients. Through content analysis, we explored ways in which the CCT positively or negatively impacted on peer relationships. From the recipients’ viewpoint, the CCT improved their social standing within their peer groups. It facilitated peer identity and promoted social connectedness among AGYW receiving the CCT. Receipt of the CCT enabled AGYW to resemble and behave like their peers who had money, allowing their poverty to become “invisible”. The CCT facilitated social interactions, information sharing, and instrumental social support among AGYW. CCT recipients experienced an increase in their social capital, evident in their ability to network, share, and reciprocate with others. However, the CCT also evoked negative emotions such as jealousy, anxiety, and resentment among non-recipients and led to a deterio‑ ration of personal relationships. CCTs have enormous benefts for AGYW, but they may also have a negative impact on peer relationships. The imple‑ mentation of HIV prevention interventions focused on structural drivers needs to be conscious of these dynamics and ensure that the negative consequences do not outweigh benefts.Item Emotional Violence is Associated with Increased HIV Risk Behavior Among South African Adolescent Girls and Young Women in the HPTN 068 Cohort(2021-11-06) Anna M. Leddy; Amanda Selin; Sheri A. Lippman; Linda J. Kimaru; Rhian Twine; Xavier Gómez‑Olivé; Kathleen Kahn; Audrey PettiforLimited research has explored how emotional intimate partner violence (IPV) shapes HIV risk behaviors. Using crosssectional data from the HPTN 068 post-trial visit (N=1942), we assessed the association between emotional IPV and its sub-domains (verbal abuse and threats) with condomless sex, transactional sex, and frequent alcohol use among young women in South Africa. In adjusted multivariable logistic regression models, any emotional IPV and verbal IPV were associated with increased odds of condomless sex (aOR: 1.47; 95% CI: 1.15, 1.87; and aOR: 1.48; 95% CI: 1.15, 1.89), transactional sex (aOR: 2.32; 95% CI: 1.74, 3.08; and aOR: 2.02; 95% CI: 1.51, 2.71) and alcohol use (aOR: 1.88; 95% CI: 1.39, 2.53; and aOR: 1.87; 95% CI: 1.37, 2.55). Threats were associated with transactional sex (aOR: 3.67; 95% CI: 2.62, 5.14). Future research should examine this relationship over-time and HIV prevention programs should consider and address emotional IPV.Item Examining Mediators of the Relationship Between Community Mobilization and HIV Incidence Among Young South African Women Participating in the HPTN 068 Study Cohort(2021-10-07) Anna M. Leddy; Torsten B. Neilands; Rhian Twine; Kathleen Kahn; Jennifer Ahern; Audrey Pettifor; Sheri A. LippmanItem A community mobilization intervention to improve engagement in HIV testing, linkage to care, and retention in care in South Africa: a cluster-randomized controlled trial(2022-09) Sheri A.

Xavier Gómez Olivé; Dumisani Rebombo; Nicole Haberland; Julie Pulerwitz; Louis Pappie Majuba; Stephen Tollman; Kathleen KahnBackground: Community Mobilization (CM), engaging communities in a process to collectively enact change, could improve HIV testing and care engagement. We assessed whether CM increased HIV testing, linkage to, and retention in care over time in intervention relative to control communities. Methods: Fifteen communities in Mpumalanga, South Africa were randomized to either a CM intervention engaging residents to address social barriers to HIV testing and treatment or to control. Implementation occurred from August 2015-July 2018. Outcomes included quarterly rates of HIV testing, linkage to care, and retention in care documented from health facility records among 18-49 year-old residents of intervention and control communities over the three years of study. Intention-to-treat analyses employed generalized estimating equations stratified by sex. ClinicalTrials.gov number NCT02197793. Findings: Residents in eight intervention communities (N=20,544) and seven control communities (N=17,848) contributed data. Among men, HIV testing increased quarterly by 12·1% (Relative Change (RC):1·121, 95%CI:1·099-1·143) in intervention communities and 9·5% (RC:1·095, 95%CI:1·075-1·114) in control communities; differences by arm were marginally significant (exponentiated interaction coefficient:1·024, 95%CI:0·997-1·052, p-value=0·078). Among women, HIV testing increased quarterly by 10·6% (RC:1·106, 95%CI:1·097-1·114) in intervention and 9·3% (RC:1·093, 95%CI:1·084-1·102) in control communities; increases were greater in intervention communities (exponentiated interaction coefficient:1·012, 95%CI:1·001-1·023, p-value=0·043). Quarterly linkage increased significantly among intervention community women (RC:1·013, 95%CI:1·002-1·023) only. Quarterly retention fell among women in both arms; however, reductions were tempered among intervention women (exponentiated interaction coefficient:1·003, 95%CI:<1·000-1·006, p-value=0·062). No significant differences were detected in linkage or retention among men. Interpretation: CM was associated with modest improvements in select trial outcomes. The sum of these incremental, quarterly improvements achieved by addressing social barriers to HIV care engagement can impact epidemic control. However, achieving optimal impacts will likely require integrated efforts addressing both social barriers through CM and provision of improved service delivery.Item Associations between WASH-related violence and depressive symptoms in adolescent girls and young women in South Africa (HPTN 068): a cross-sectional analysis(2022-07-05) Ruvani T Jayaweera; Dana Goin; Rhian Twine; Torsten B Neilands; Ryan G Wagner; Sheri A Lippman; Kathleen Kahn; Audrey Pettifor; Jennifer AhernObjective: There is a lack of research on experiences of WASH-related violence. This study aims to quantify the association between experience or worry of violence when using the toilet or collecting water and depressive symptoms among a cohort of young women in South Africa. Methods: Data are from visit 3 of the HPTN 068 cohort of adolescent girls in rural Mpumalanga Province, South Africa. Participants (n=1798) included in this analysis were aged 13-21 at baseline. Lifetime experience of violence or fear of violence when using the toilet and collecting water was collected by self-report; depressive symptoms in the past week were measured using the Center for Epidemiological Studies Depression Scale (CES-D). We used G-computation to calculate the prevalence difference (PD) and prevalence ratio of depression (CES-D score >15) associated with each domain of violence, controlling for baseline covariates. Findings: A total of 15.1% of respondents reported experiencing violence when using the toilet; 17.1% reported experiencing violence when collecting water and 26.7% reported depression. In adjusted models, those who reported experiencing violence when using the toilet had an 18.1% higher prevalence of depression (95% CI: 11.6% to 24.4%) than those who did not experience violence when using the toilet. Adjusted prevalence of depression was also higher among those who reported violence when collecting water (PD 11.9%, 95% CI: 6.7% to 17.2%), and who worried about violence when using the toilet (PD 12.8%, 95% CI: 7.9% to 19.8%), as compared with those who did not report these experiences. Worrying about violence when collecting water was not associated with depression after adjusting for covariates. Conclusion: Experience of WASH-related violence is common among young women in rural South Africa, and experience or worry of experiencing violence is associated with higher prevalence of depressive symptoms.Item The Sky is the Limit; I am Going There”: Experiences of Hope Among Young Women Receiving a Conditional Cash Transfer in Rural South Africa(2021-05-05) Kaitlyn Atkins; Catherine MacPhail; Suzanne Maman; Nomhle Khoza; Rhian Twine; F Xavier Gomez-Olive; Audrey Pettifor; Kathleen KahnYoung women in South Africa face elevated risk of HIV infection compared to male peers. Cash transfers may mitigate their risk for HIV; however, there is limited understanding of mechanisms of impact. We explored hope as one potential mechanism. Longitudinal qualitative analysis was used to explore how cash transfer recipients in the HPTN 068 study conceptualised hope and how the intervention influenced their hope over time. We found the intervention increased confidence, alleviated financial stressors and instilled in young women the belief that a better life, defined as being educated, independent and supportive to family, was attainable. Findings support hope as a critical outcome of cash transfer and other economic strengthening interventions.Item Associations between WASH-related violence and depressive symptoms in adolescent girls and young women in South Africa (HPTN 068): a crosssectional analysis(2022-06-13) Ruvani T Jayaweera; Dana Goin; Rhian Twine; Torsten B Neilands; Ryan G Wagner; Sheri A Lippman; Kathleen Kahn; Audrey Pettifor; Jennifer AhernObjective There is a lack of research on experiences of WASH-related violence.

Hope mediated the relationship between average household age and sexual debut (mediated effect = −0.003, p<.05), and between household consumption and sexual debut (mediated effect = −0.019, p<.05). Both higher average household age (β = 0.01; 95%CI: 0.00, 0.01) and greater household consumption (β = 0.05; 95%CI: 0.02, 0.08) were marginally associated with higher hope. In turn, greater hope was associated with lower odds of sexual debut (aOR= 0.62; 95%CI: 0.52, 0.74). These results provide important preliminary evidence of the role of the home environment in shaping protective psychological assets and healthy sexual behaviors. Continued exploration of the relationship between hope and the home environment may help to explain why young women in this context have a disproportionate risk for HIV.Item Men’s perspectives on the impact of femaledirected cash transfers on gender relations: Findings from the HPTN 068 qualitative study(2018) Makhosazane Nomhle Khoza; Sinead Delany-Moretlwe; Fiona Scorgie; Jennifer Hove; Amanda Selin; John Imrie; Rhian Twine; Kathleen Kahn; Audrey Pettifor; Catherine MacPhailBackground HIV is an inherently gendered disease in eastern and southern Africa, not only because more women than men are infected, but also because socially constructed gender norms work to increase women’s HIV-infection risk. The provision of cash transfers to young women alone in such a context adds another dimension to already existing complex social relations where patriarchal values are entrenched, gender inequality is the norm, and violence against women and girls is pervasive. It raises concerns about complicating young women’s relationships with their male partners or possibly even setting them up for more violence. In our attempt to understand how cash transfers influence social relations in the context of a trial among young women in South Africa, we used qualitative data collected during the trial to explore men’s perceptions of the impact of cash transfers on male-female relationships, both intimate and platonic, peer relationships. Method Between April 2012 and August 2015, we conducted focus group discussions (n = 12) and interviews (n = 20) with the male peers and intimate partners of young women aged 13–20 years, who were participating in a phase III randomised controlled trial of CTs for HIV prevention in Mpumalanga, South Africa. A thematic content analysis approach was used to analyse the data. The codebook was developed on the basis of the topic guides, with additional codes added inductively as they emerged from the data. Results Intimate partners were older (range 20–32 years) and more likely to be working than the male peers. Both intimate partners and male peers were supportive of the CT trial targeting young women; younger peers however expressed some concerns that the money might diminish their power and status in relationships. HIV testing requirements associated with the trial appeared to have improved communication about sex and HIV in intimate relationships, with some women even encouraging their partners to go for an HIV test. Conclusion CTs provide AGYW with a measure of autonomy and power to contribute in their gendered relationships, albeit in limited ways. However, there is potential for CTs to have a negative impact on male-female relationships if the cash received by AGYW is equal to or greater than the income earned by their male counterparts or sexual partners.Item Cash transfers for HIV prevention: what do young women spend it on? Mixed methods findings from HPTN 068(2018) Catherine MacPhail; Nomhle Khoza; Amanda Selin; Aimée Julien; Rhian Twine; Ryan G. Wagner; Xavier Goméz-Olivé; Kathy Kahn; Jing Wang; Audrey PettiforBackground Social grants have been found to have an impact on health and wellbeing in multiple settings. Who receives the grant, however, has been the subject of discussion with regards to how the money is spent and who benefits from the grant. Methods Using survey data from 1214 young women who were in the intervention arm and completed at least one annual visit in the HPTN 068 trial, and qualitative interview data from a subset of 38 participants, we examined spending of a cash transfer provided to young women conditioned on school attendance. Results We found that spending was largely determined and controlled by young women themselves and that the cash transfer was predominately spent on toiletries, clothing and school supplies. In interview data, young women discussed the significant role of cash transfers for adolescent identity, specifically with regard to independence from family and status within the peer network. There were almost no negative consequences from receiving the cash transfer. Conclusions We established that providing adolescents access to cash was not reported to be associated with social harms or negative consequences. Rather, spending of the cash facilitated appropriate adolescent developmental behaviors. The findings are encouraging at a time in which there is global interest in addressing the structural drivers of HIV risk, such as poverty, for young women.
