Emotional Violence is Associated with Increased HIV Risk Behavior Among South African Adolescent Girls and Young Women in the HPTN 068 Cohort.

Limited research has explored how emotional intimate partner violence (IPV) shapes HIV risk behaviors. Using cross-sectional 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.

The impact of conditional cash transfers for HIV prevention on peer relationships: perspectives from female recipients and non-recipients in HPTN 068.

CCTs are currently being explored for HIV prevention among adolescent girls and young women (AGYW) in Southern Africa. However, little is known about how CCT geared towards adolescents' influence peer relationships, despite evidence that peer relationships form a critical part of development in adolescence. This article presents findings 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 deterioration of personal relationships.CCTs have enormous benefits for AGYW, but they may also have a negative impact on peer relationships. The implementation of HIV prevention interventions focused on structural drivers needs to be conscious of these dynamics and ensure that the negative consequences do not outweigh benefits.

Depression and Incident HIV in Adolescent Girls and Young Women in HIV Prevention Trials Network 068: Targets for Prevention and Mediating Factors.

The human immunodeficiency virus (HIV) epidemic among adolescent girls and young women (AGYW) in sub-Saharan Africa is a critical public health problem. We assessed whether depressive symptoms in AGYW were longitudinally associated with incident HIV, and identified potential social and behavioral mediators. Data came from a randomized trial of a cash transfer conditional on school attendance among AGYW (ages 13-21 years) in rural Mpumalanga Province, South Africa, during 2011-2017. We estimated the relationship between depressive symptoms and cumulative HIV incidence using a linear probability model, and we assessed mediation using inverse odds ratio weighting. Inference was calculated using the nonparametric bootstrap. AGYW with depressive symptoms had higher cumulative incidence of HIV compared with those without (risk difference = 3.5, 95% confidence interval (CI): 0.1, 7.0). The strongest individual mediators of this association were parental monitoring and involvement (indirect effect = 1.6, 95% CI: 0.0, 3.3) and reporting a partner would hit her if she asked him to wear a condom (indirect effect = 1.5, 95% CI: -0.3, 3.3). All mediators jointly explained two-thirds (indirect effect = 2.4, 95% CI: 0.2, 4.5) of the association between depressive symptoms and HIV incidence. Interventions addressing mental health might reduce risk of acquiring HIV among AGYW.

Correlates of ART Use Among Newly Diagnosed HIV Positive Adolescent Girls and Young Women Enrolled in HPTN 068.

Despite expanded access to HIV treatment worldwide, poor HIV care outcomes persist among adolescent girls and young women (AGYW). This study was conducted among AGYW recruited from the HPTN 068 cohort who had sero-converted to HIV during the main trial between 2011 and 2014. The aim was to examine correlates of anti-retroviral treatment (ART) use. Log binomial regression was used to estimate the crude associations between social support, stigma, and HIV status disclosure and current ART use. Adjusted analyses were also conducted controlling for age and time since diagnosis. Seventy-nine AGYW were included in this analysis. Median age of participants was 20 (range: 17 to 24) and time since diagnosis ranged from 0.5 to 4.8 years (median = 2.1). Over 75% of AGYW (n = 60) had sought HIV care at some point, with the same number reporting previous disclosure of their sero-status. However, just 43% (n = 34) of participants were on treatment at the time of the interview. Over half of participants (n = 44; 55.7%) reported social support was available to them most or all of the time, and the median stigma score was 90 (range 80-113). Adjusted analyses found higher current ART use among those who had disclosed their status (adjusted prevalence ratio (aPR): 3.19; 95% confidence interval (CI) 1.09, 9.32; p = 0.0339) and those with lower scores on the disclosure concern sub-scale of the Berger HIV Stigma Scale (aPR: 0.88; 95% CI 0.79, 0.98; p = 0.0236). ART use among AGYW living with HIV and enrolled in HPTN 068 was low despite relatively high linkage to care during the trial. Interventions aimed at minimizing individuals' concerns about disclosure and improving onward disclosure of one's status could further improve ART utilization among AGYW living with HIV in South Africa.

The effects of a cash transfer intervention on sexual partnerships and HIV in the HPTN 068 study in South Africa.

Evidence on cash transfer interventions for HIV prevention in adolescent girls and young women is unclear and indicates that they may not work uniformly in all settings. Qualitative interviews were conducted with 22 girls and young women post-intervention to determine how a cash transfer study (HPTN 068) in South Africa was perceived to influence sexual behaviours and to explore mechanisms for these changes. Participants described how the intervention motivated them to increase condom use, have fewer partners, end risky relationships and access HIV testing services at local primary health clinics. Changes were attributed to receipt of the cash transfer, in addition to HIV testing and sexual health information. Processes of change included improved communication with partners and increased negotiation power in sexual decision-making. Economic empowerment interventions increase confidence in negotiating behaviours with sexual partners and are complementary to sexual health information and health services that provide young women with a foundation on which to make informed decisions about how to protect themselves.

Friendships Among Young South African Women, Sexual Behaviours and Connections to Sexual Partners (HPTN 068).

Friends could be influential on young women's sexual health via influences on sexual behaviours and as connections to sexual partners, but are understudied in sub-Saharan Africa. We cross-sectionally surveyed 2326 13-20 year-old young women eligible for grades 8-11 in rural South Africa about their sexual behaviour and up to three sexual partners. Participants each described five specific but unidentified friends and the relationships between them in an 'egocentric' network analysis design. We used logistic regression to investigate associations between friendship characteristics and participants' reports of ever having had sex (n = 2326) and recent condom use (n = 457). We used linear regression with random effects by participant to investigate friendship characteristics and age differences with sexual partners (n = 633 participants, 1051 partners). We found that it was common for friends to introduce young women to those who later became sexual partners, and having older friends was associated with having older sexual partners, (increase of 0.37 years per friend at least 1 year older, 95% CI 0.21-0.52, adjusted). Young women were more likely to report ever having had sex when more friends were perceived to be sexually active (adjusted OR 1.85, 95% CI 1.72-2.01 per friend) and when they discussed sex, condoms and HIV with friends. Perception of friends' condom use was not associated with participants' reported condom use. While this study is preliminary and unique in this population and further research should be conducted, social connections between friends and sexual partners and perceptions of friend sexual behaviours could be considered in the design of sexual health interventions for young women in South Africa.

HIV self-testing: South African young adults' recommendations for ease of use, test kit contents, accessibility, and supportive resources.

BACKGROUND: The uptake of HIV self-testing (HIVST) could address socio-structural barriers that prevent South African youth from utilizing the testing resources available in their communities. However, to facilitate this, we must tailor components of the HIVST kit and process to ensure that we reach and encourage youth to test. The purpose of this study to elucidate concerns and issues regarding HIVST rollout among South African youth. METHODS: This study was conducted in two phases: 1) focus group discussions with rural, South African youth aged 18-24 and 2) direct observations of participants completing with an oral HIVST kit and/or a blood based HIVST kit. In phase 2a participants were invited to try both an oral and blood-based HIVST kit. In phase 2b, participants selected the HIVST kit of their choice. RESULTS: We enrolled 35 unique participants in phase 1, 20 participants in phase 2a, and 40 participants in phase 2b. While the focus group discussions highlighted hypothetical HIVST use only, participants appreciated the privacy that the HIVST could afford them. However, they expressed concerns about whether HIVST could be trusted due to false positives and negatives, as well as whether a person would be able to emotionally handle the results if they tested alone. They suggested that the kits be used alongside someone who could provide support. In phases 2a and 2b, participants were overwhelmingly positive about both kits regarding ease of use and whether their results could be trusted. The participants, however, experienced more challenges with the blood-based versus oral test. When given the choice in phase 2b, most participants (80%) chose the oral HIVST over the blood-based HIVST. CONCLUSIONS: During the focus group discussions, participants raised concerns about the validity of HIVST, lack of emotional support when testing alone, and the cost of HIVST kits, all of which could be addressed through current testing campaigns. Most of those who actually tested had positive experiences with HIVST and would recommend it to their friends. When offered a choice, most preferred the oral test.

'It's because I like things it's a status and he buys me airtime': exploring the role of transactional sex in young women's consumption patterns in rural South Africa (secondary findings from HPTN 068).

BACKGROUND: 'Transactional sex', defined as a non-marital, non-commercial sexual relationship in which money or material goods are exchanged for sex, is associated with young women's increased vulnerability to HIV infection. Existing research illustrates that the motivations for transactional sex are complex. The fulfilment of psycho-social needs such as the need to belong to a peer group are important factors underlying young women's desires to obtain certain consumption items and thus engage in transactional sex. METHODS: We use a mixed-methods approach to explore the relationship between transactional sex and consumption patterns among young women in rural Mpumalanga province, South Africa. In the secondary analysis of 693 sexually active young women, we use factor analysis to group the different consumption items and we use multivariable logistic regression to demonstrate the relationship between transactional sex and consumption patterns. The qualitative study uses five focus group discussions and 19 in-depth interviews to explore further young women's motivations for acquiring different consumption items. RESULTS: The quantitative results show that young women that engage in transactional sex have higher odds of consuming items for entertainment (e.g., movie tickets) than on practical items (e.g., food and groceries). The qualitative findings also revealed that young women's perceptions of items that were considered a 'need' were strongly influenced by peer pressure and a desire for improved status. Further, there was a perception that emerged from the qualitative data that relationships with sugar daddies offered a way to acquire consumer goods associated with a 'modern lifestyle', such as items for personal enhancement and entertainment. However, young women seem aware of the risks associated with such relationships. More importantly, they also develop relationship with partners of similar age, albeit with the continued expectation of material exchange, despite engaging in the relationship for love. CONCLUSION: This study shows that young women are willing to take certain risks in order to have a degree of financial independence. Interventions that provide alternative methods of attaining this independence, such as the provision of cash transfers may have potential in preventing them from engaging in transactional relationships. Further, the psycho-social reasons that drive young women's motivations for consumption items resulting in risky sexual behaviours need to be better understood.

Economic Resources and HIV Preventive Behaviors Among School-Enrolled Young Women in Rural South Africa (HPTN 068).

Individual economic resources may have greater influence on school-enrolled young women's sexual decision-making than household wealth measures. However, few studies have investigated the effects of personal income, employment, and other financial assets on young women's sexual behaviors. Using baseline data from the HIV Prevention Trials Network (HPTN) 068 study, we examined the association of ever having sex and adopting sexually-protective practices with individual-level economic resources among school-enrolled women, aged 13-20 years (n = 2533). Age-adjusted results showed that among all women employment was associated with ever having sex (OR 1.56, 95 % CI 1.28-1.90). Among sexually-experienced women, paid work was associated with changes in partner selection practices (OR 2.38, 95 % CI 1.58-3.58) and periodic sexual abstinence to avoid HIV (OR 1.71, 95 % CI 1.07-2.75). Having money to spend on oneself was associated with reducing the number of sexual partners (OR 1.94, 95 % CI 1.08-3.46), discussing HIV testing (OR 2.15, 95 % CI 1.13-4.06), and discussing condom use (OR 1.99, 95 % CI 1.04-3.80). Having a bank account was associated with condom use (OR 1.49, 95 % CI 1.01-2.19). Economic hardship was positively associated with ever having sex, but not with sexually-protective behaviors. Maximizing women's individual economic resources may complement future prevention initiatives.

Cash transfers for HIV prevention: what do young women spend it on? Mixed methods findings from HPTN 068.

BACKGROUND: 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 behaviours. 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.

Measuring Men's Gender Norms and Gender Role Conflict/Stress in a High HIV-Prevalence South African Setting.

Gender norms and gender role conflict/stress may influence HIV risk behaviors among men; however scales measuring these constructs need further development and evaluation in African settings. We conducted exploratory and confirmatory factor analyses to evaluate the Gender Equitable Men's Scale (GEMS) and the Gender Role Conflict/Stress (GRC/S) scale among 581 men in rural northeast South Africa. The final 17-item GEMS was unidimensional, with adequate model fit and reliability (alpha = 0.79). Factor loadings were low (0.2-0.3) for items related to violence and sexual relationships. The final 24-item GRC/S scale was multidimensional with four factors: Success, power, competition; Subordination to women; Restrictive emotionality; and Sexual prowess. The scale had adequate model fit and good reliability (alpha = 0.83). While GEMS is a good measure of inequitable gender norms, new or revised scale items may need to be explored in the South African context. Adding the GRC/S scale to capture men's strain related to gender roles could provide important insights into men's risk behaviors.

HPTN 068: A Randomized Control Trial of a Conditional Cash Transfer to Reduce HIV Infection in Young Women in South Africa-Study Design and Baseline Results.

Young women in South Africa are at high risk for HIV infection. Cash transfers offer promise to reduce HIV risk. We present the design and baseline results from HPTN 068, a phase III, individually randomized trial to assess the effect of a conditional cash transfer on HIV acquisition among South African young women. A total of 2533 young women were randomized to receive a monthly cash transfer conditional on school attendance or to a control group. A number of individual-, partner-, household- and school-level factors were associated with HIV and HSV-2 infection. After adjusting for age, all levels were associated with an increased odds of HIV infection with partner-level factors conveying the strongest association (aOR 3.05 95 % CI 1.84-5.06). Interventions like cash transfers that address structural factors such as schooling and poverty have the potential to reduce HIV risk in young women in South Africa.

Relationship between community-level alcohol outlet accessibility and individual-level herpes simplex virus type 2 infection among young women in South Africa.

BACKGROUND: Exposure to alcohol outlets may influence sexual health outcomes at the individual and community levels. Visiting alcohol outlets facilitates alcohol consumption and exposes patrons to a risky environment and network of potential partners, whereas the presence of alcohol outlets in the community may shift social acceptance of riskier behavior. We hypothesize that living in communities with more alcohol outlets is associated with increased sexual risk. METHODS: We performed a cross-sectional analysis in a sample of 2174 South African schoolgirls (ages 13-21 years) living across 24 villages in the rural Agincourt subdistrict, underpinned by long-term health and sociodemographic surveillance. To examine the association between number of alcohol outlets in village of residence and individual-level prevalent herpes simplex virus type 2 (HSV-2) infection, we used generalized estimating equations with logit links, adjusting for individual- and village-level covariates. RESULTS: The median number of alcohol outlets per village was 3 (range, 0-7). Herpes simplex virus type 2 prevalence increased from villages with no outlets (1.4% [95% confidence interval, 0.2-12.1]), to villages with 1 to 4 outlets (4.5% [3.7-5.5]), and to villages with more than 4 outlets (6.3% [5.6, 7.1]). An increase of 1 alcohol outlet per village was associated with an 11% increase in the odds of HSV-2 infection (adjusted odds ratio [95% confidence interval], 1.11 [0.98-1.25]). CONCLUSIONS: Living in villages with more alcohol outlets was associated with increased prevalence of HSV-2 infection in young women. Structural interventions and sexual health screenings targeting villages with extensive alcohol outlet environments could help prevent the spread of sexually transmitted infections.

A cluster randomized-controlled trial of a community mobilization intervention to change gender norms and reduce HIV risk in rural South Africa: study design and intervention.

BACKGROUND: Community mobilization (CM) interventions show promise in changing gender norms and preventing HIV, but few have been based on a defined mobilization model or rigorously evaluated. The purpose of this paper is to describe the intervention design and implementation and present baseline findings of a Cluster Randomized Controlled Trial (RCT) of a two-year, theory-based CM intervention that aimed to change gender norms and reduce HIV risk in rural Mpumalanga province, South Africa. METHODS: Community Mobilizers and volunteer Community Action Teams (CATs) implemented two-day workshops, a range of outreach activities, and leadership engagement meetings. All activities were mapped onto six theorized mobilization domains. The intervention is being evaluated by a randomized design in 22 communities (11 receive intervention). Cross-sectional, population-based surveys were conducted with approximately 1,200 adults ages 18-35 years at baseline and endline about two years later. CONCLUSIONS: This is among the first community RCTs to evaluate a gender transformative intervention to change norms and HIV risk using a theory-based, defined mobilization model, which should increase the potential for impact on desired outcomes and be useful for future scale-up if proven effective. TRIAL REGISTRATION: ClinicalTrials.gov NCT02129530.

Acceptability and feasibility of cash transfers for HIV prevention among adolescent South African women.

Women are at increased risk of HIV infection in much of sub-Saharan Africa. Longitudinal and cross-sectional studies have found an association between school attendance and reduced HIV risk. We report feasibility and acceptability results from a pilot of a cash transfer intervention conditional on school attendance paid to young women and their families in rural Mpumalanga, South Africa for the prevention of HIV infection. Twenty-nine young women were randomised to intervention or control and a cash payment based on school attendance made over a 2-month period. Quantitative (survey) and qualitative (focus group and interview) data collection was undertaken with young women, parents, teachers and young men in the same school. Qualitative analysis was conducted in Atlas.ti using a framework approach and basic descriptive analysis in Excel was conducted on the quantitative data. Results indicate it was both feasible and acceptable to introduce such an intervention among this population in rural South Africa. There was good understanding of the process of randomisation and the aims of the study, although some rumours developed in the study community. We address some of the changes necessary to ensure acceptability and feasibility of the main trial.

HIV self-testing among young women in rural South Africa: A randomized controlled trial comparing clinic-based HIV testing to the choice of either clinic testing or HIV self-testing with secondary distribution to peers and partners.

BACKGROUND: HIV testing rates in many hyper-endemic areas are lower than needed to curtail the HIV epidemic. New HIV testing strategies are needed to overcome barriers to traditional clinic based testing; HIV self-testing is one modality that offers promise in reaching individuals who experience barriers to clinic-based testing. METHODS: We conducted a randomized control trial among young women ages 18-26 living in rural Mpumalanga, South Africa where they were randomized in a 1:1 allocation to either the: (1) HIV Counseling and Testing (HCT) arm: an invitation to test at one of the 9 local government clinics where free HCT is provided and is standard of care (SOC), or (2) choice arm: choice of either a clinic-based HCT invitation or oral HIV Self-Testing (HIVST) kits. Depending on the arm, participants were also provided either: (1) 4 HCT invitations to provide to peers/partners for HIV testing at one of the 9 local clinics, or (2) 4 HIV self-test kits to provide to peers/partners (thus 5 total HIVST kits or HCT invitations). Young women were asked to return 3 months and 9 months after enrollment to assess testing uptake and invitation or kit distribution to peers and partners and experiences with testing. Peers and partners who were reported by index participants to have received kits/invitations during follow-up visits were also invited to attend a study visit to assess their testing experiences. The trial is registered at clinical trials.gov NCT03162965. FINDINGS: 287 young women were enrolled and randomized, with 146 randomized to the HCT arm and 141 to the choice (HCT or HIVST) arm. Of those randomized to the choice arm, over 95% (n=135) chose the HIV self-testing kit and only 6 individuals chose HCT. At the 3-month follow-up visit, 92% of index participants in the choice arm reported having tested for HIV compared to 43% of participants in the HCT arm, resulting in a significant risk difference of 49% (95% CI 40%, 58%). By 9 months, this difference decreased to a risk difference of 25% (95% CI 17%, 33%) between arms (96% in the choice arm and 72% in the HCT arm). Participants in the choice arm were also more likely to invite peers and partners to test compared to the HCT arm (94% vs. 76% or an average of 4.97 vs 2.79 tests). Few male partners were invited to test by index participants; however, index participants in the choice arm were more likely to have their male partners test than index participants in the HCT arm (RR 2.99, 95% CI 1.45, 6.16). INTERPRETATION: When given a choice between clinic-based HIV testing and HIV oral self-testing, the overwhelming majority of young women chose HIVST. In addition, those offered a choice of HIV testing modality were much more likely to test, distribute test kits to peers and partners, and to have peers and partners who reported testing compared to the HCT arm. Self-testing offers an important opportunity to significantly increase testing rates among young women and their peers and partners compared to clinic-based HCT. Other strategies to reach men with testing are needed. FUNDING: US National Institutes of Health.

Longitudinal Trajectories of Physical Intimate Partner Violence Among Adolescent Girls in Rural South Africa: Findings From HPTN 068.

PURPOSE: Little is known about temporal patterns of physical intimate partner violence (PIPV) among South African adolescent girls. We sought to identify and describe PIPV risk trajectories and related correlates in this population. METHODS: Our analytical cohort came from the HPTN 068 Cash Transfer Trial in Mpumalanga Province, South Africa. Cohort members were eighth and ninth graders (median age 14 years) who enrolled in 2011 and had three to four annual, self-reported PIPV measurements. We used group-based trajectory models to identify groups of girls with similar longitudinal patterns of PIPV risk over 4 years and potential correlates of group membership. RESULTS: We identified two trajectory groups (n = 907): a higher-risk group (~52.8% of the cohort) with predicted PIPV probabilities of 13.5%-41.1% over time and a lower-risk group (~47.2% of the cohort) with predicted probabilities of 2.3%-10.3%. Baseline correlates of higher-risk group membership were ever having had sex (adjusted odds ratio [aOR]: 4.42, 95% confidence interval [CI]: 1.56-12.57), borrowing money (aOR: 1.95, 95% CI: 1.01-3.79), and older age (aOR per 1-year increase: 1.39, 95% CI: 1.11-1.73), while being in the 068 intervention arm (aOR: .29, 95% CI: .17-.51) and supporting more gender-equitable norms (aOR per 1-unit score increase: .89, 95% CI: .81-.97) were inversely associated. CONCLUSIONS: A high proportion of adolescent girls experience sustained PIPV risk in rural South Africa, suggesting a need for interventions in late primary school that encourage gender-equitable norms, healthy relationships, and safe ways to earn income during adolescence.

The association between perceived household educational support and HIV risk in young women in a rural South African community (HPTN 068): A cross sectional study.

OBJECTIVE: To characterise perceived household support for female education and the associations between educational support and HIV prevalence, HSV-2 prevalence and sexual risk behaviours. METHODS: This cross-sectional study used baseline survey data from the Swa Koteka HPTN 068 trial undertaken in Mpumalanga, South Africa. The study included 2533 young women aged 13-20, in grades 8-11 at baseline. HIV and HSV-2 status were determined at baseline. Information about patterns of sexual behaviour and household support for education was collected during the baseline survey. Linear regression and binary logistic regression were used to determine associations between household support for education and both biological and behavioural outcomes. RESULTS: High levels of educational support were reported across all measures. HIV prevalence was 3.2% and HSV-2 prevalence was 4.7%, both increasing significantly with age. Over a quarter (26.6%) of young women reported vaginal sex, with 60% reporting condom use at last sex. The median age of sexual debut was 16 years. Household educational support was not significantly associated with HIV or HSV-2; however, the odds of having had vaginal sex were significantly lower in those who reported greater homework supervision (OR 0.82, 95%CI: 0.72-0.94), those who engaged in regular discussion of school marks with a caregiver (OR 0.82, 95%CI: 0.71-0.95) and when caregivers had greater educational goals for the young woman (OR 0.82, 95%CI: 0.71-0.96). In contrast, greater caregiver disappointment at dropout was significantly associated with reported vaginal sex (OR 1.29, 95%CI: 1.14-1.46). CONCLUSION: Young women in rural South Africa report experiencing high levels of household educational support. This study suggests that greater household educational support is associated with lower odds of having vaginal sex and engaging in risky sexual behaviour, though not with HIV or HSV-2 prevalence.

The Relationship Between School Dropout and Pregnancy Among Adolescent Girls and Young Women in South Africa: A HPTN 068 Analysis.

Background. Prevention of both school dropout and teen pregnancy represent clear public health priorities for South Africa, yet their complex and potentially cyclical relationship has not been fully explored. Objective. To further understand how this relationship operates, we analyzed data from a randomized trial of young women aged 13 to 20 years enrolled in school in rural South Africa to estimate the association between pregnancy and subsequent dropout and between dropout and subsequent pregnancy. Method. We examined inverse probability (IP) of exposure-weighted survival curves for school dropout by pregnancy and for pregnancy by school dropout. We used weighted curves to calculate 1-, 2-, and 3-year risk differences and risk ratios. Additionally, we used an IP-weighted marginal structural cox model to estimate a hazard ratio (HR) for each relationship. Results. Dropout from school was associated with subsequent pregnancy (HR 3.58; 95% confidence interval [CI] [2.04, 6.28]) and pregnancy was associated with subsequent school dropout (HR 2.36; 95% CI [1.29, 4.31]). Young women who attended school but attended fewer days had a higher hazard of pregnancy than those who attended more school (HR 3.64; 95% CI [2.27, 5.84]). Conclusion. Pregnancy is both a cause and a consequence of school dropout. Consideration of school attendance and academic performance could ultimately enhance pregnancy prevention efforts in this population. Programs should be tailored differently for (1) girls who have dropped out of school, (2) those who are in school and at risk for pregnancy, and (3) those who are in school and become pregnant.

Prevalence and Associations, by Age Group, of IPV Among AGYW in Rural South Africa.

The prevalence of intimate partner violence (IPV) is alarmingly high among South African adolescent girls and young women (AGYW). Limited data exist exploring how IPV prevalence and its risk factors differ by age. Study data were from the baseline visit of HPTN 068, a randomized controlled trial (RCT) conducted from 2011 to 2015 in Mpumalanga, South Africa. A cohort of 2,533 AGYW, aged 13 years to 20 years, answered survey questions on demographics and behaviors, including their experiences of physical and sexual violence ever and in the past 12 months. We calculated the prevalence of IPV and related risk factors, as well as prevalence ratios with 95% confidence intervals, stratified by age. Nearly one quarter (19.5%, 95% CI = [18.0, 21.2]) of AGYW experienced any IPV ever (physical or sexual) by a partner. The prevalence of any IPV ever among AGYW aged 13 years to 14 years, 15 years to 16 years, and 17 years to 20 years was 10.8%, 17.7%, and 32.1%, respectively. Key variables significantly associated with any IPV ever across all age groups included borrowing money from someone outside the home in the past 12 months, ever having had vaginal sex, ever having had anal sex, and consuming any alcohol. Few statistically significant associations were unique to specific age groups. The history of IPV among the youngest AGYW is a critical finding and should be a focus of prevention efforts.
