Directed and target focused multi-sectoral adolescent HIV prevention: Insights from implementation of the 'DREAMS Partnership' in rural South Africa

A mixed methods process evaluation: understanding the implementation and delivery of HIV prevention services integrated within sexual reproductive health (SRH) with or without peer support amongst adolescents and young adults in rural KwaZulu-Natal, South Africa

BACKGROUND

Combination prevention interventions, when integrated with community-based support, have been shown to be particularly beneficial to adolescent and young peoples' sexual and reproductive health. Between 2020 and 2022, the Africa Health Research Institute in rural South Africa conducted a 2 × 2 randomised factorial trial among young people aged 16-29 years old (Isisekelo Sempilo) to evaluate whether integrated HIV and sexual and reproductive health (HIV/SRH) with or without peer support will optimise delivery of HIV prevention and care. Using mixed methods, we conducted a process evaluation to provide insights to and describe the implementation of a community-based peer-led HIV care and prevention intervention targeting adolescents and young people.

METHODS

The process evaluation was conducted in accordance with the Medical Research Council guidelines using quantitative and qualitative approaches. Self-completed surveys and clinic and programmatic data were used to quantify the uptake of each component of the intervention and to understand intervention fidelity and reach. In-depth individual interviews were used to understand intervention experiences. Baseline sociodemographic factors were summarised for each trial arm, and proportions of participants who accepted and actively engaged in various components of the intervention as well as those who successfully linked to care were calculated. Qualitative data were thematically analysed.

RESULTS

The intervention was feasible and acceptable to young people and intervention implementing teams. In particular, the STI testing and SRH components of the intervention were popular. The main challenges with the peer support implementation were due to fidelity, mainly because of the COVID-19 pandemic. The study found that it was important to incorporate familial support into interventions for young people's sexual health. Moreover, it was found that psychological and social support was an essential component to combination HIV prevention packages for young people.

CONCLUSION

The results demonstrated that peer-led community-based care that integrates SRH services with HIV is a versatile model to decentralise health and social care. The family could be a platform to target restrictive gender and sexual norms, by challenging not only attitudes and behaviours related to gender among young people but also the gendered structures that surround them.

Uptake of multi-level HIV interventions and HIV-related behaviours among young people in rural South Africa

Combination HIV prevention packages have reduced HIV incidence and improved HIV-related outcomes among young people. However, there is limited data on how package components interact to promote HIV-related prevention behaviours. We described the uptake of HIV prevention interventions supported by Determined, Resilient, Empowered, AIDS-free, Motivated and Safe (DREAMS) Partnership and assessed the association between uptake and HIV-related behaviours among young people in rural KwaZulu-Natal, South Africa. We analysed two cohorts followed from May 2017 to December 2019 to evaluate the impact of DREAMS, covering 13-29 year-old females, and 13-35 year-old males. DREAMS interventions were categorised as healthcare-based or social. We described the uptake of interventions and ran logistic regression models to investigate the association between intervention uptake and subsequent protective HIV-related outcomes including no condomless sex and voluntary medical male circumcision (VMMC). For each outcome, we adjusted for socio-demographics and sexual/pregnancy history and reported adjusted odds ratios (aOR) and 95% confidence intervals (CI). Among 5248 participants, uptake of healthcare interventions increased from 2018 to 2019 by 8.1% and 3.7% for males and females respectively; about half of participants reported receiving both healthcare and social interventions each year. The most utilised combinations of interventions included HIV testing and counselling, school-based HIV education and cash transfers. Participation in social interventions only compared to no intervention was associated with reduced condomless sex (aOR = 1.60, 95%CI: 1.03-2.47), while participation in healthcare interventions only was associated with increased condomless sex. The uptake of interventions did not significantly affect subsequent VMMC overall. Among adolescent boys, exposure to school-based HIV education, cash transfers and HIV testing and counselling was associated with increase in VMMC (aOR = 1.79, 95%CI: 1.04-3.07). Multi-level HIV prevention interventions were associated with an increase in protective HIV-related behaviours emphasizing the importance of accessible programs within both school and community settings for young people.

Looking for the future - Hope and adolescent risk behaviour in rural KwaZulu-Natal, South Africa

ABSTRACTWe investigate the relationship between hope and risky behaviour and the role of migration among young people in northern KwaZulu-Natal, South Africa. We use data from a cohort of n = 5248 adolescents and young adults (AYA) aged 13-35 recruited and followed up in 2017-2019. We conducted a structured quantitative survey to assess levels of hope among AYA using a validated tool/scale. 44% of participants were aged 13-17 years, 63% were still in school, 66% were from rural areas, and 26% were from food insecure households. The mean hope total score was 31.7. The mean hope score was lower for females compared to males -0.43(95%CI; -0.64, -0.21) and lower for those out of school and not matriculated compared to those in school -0.72(95%CI; -1.1, -0.32). Young people who had experienced violence had a lower mean hope score than those who had not -0.28(95%CI: -0.50, -0.06). Those out of school, matriculated and unemployed were more likely to migrate than those in school (aOR = 1.60, 95%CI; 1.25, 2.05). AYA who were food insecure were also more likely to migrate (aOR = 1.23, 95%CI; 1.05, 1.43). Our findings suggest a need for structural interventions that address employment and education needs and harmful gender norms for older AYA.

Evidence of HIV incidence reduction in young women, but not in adolescent girls, in KwaZulu-Natal, South Africa

Objectives

We estimated changes in the HIV incidence from 2013-2018 in Eshowe/Mbongolwane, KwaZulu-Natal, South Africa where Médecins Sans Frontières is engaged in providing HIV testing and care since 2011.

Methods

Using data from two cross-sectional household-based surveys conducted in 2013 and 2018, with consenting participants aged 15-59 years, we applied the incidence estimation frameworks of Mahiane et al and Kassanjee et al.

Results

In total, 5599 (62.4% women) and 3276 (65.9% women) individuals were included in 2013 and 2018, respectively. We found a mean incidence in women aged 20-29 years of 2.71 cases per 100 person-years (95% confidence interval [CI]: 1.23;4.19) in 2013 and 0.4 cases per 100 person-years (95% CI: 0.0;1.5) in 2018. The incidence in men aged 20-29 years was 1.91 cases per 100 person-years (95% CI: 0.87; 2.93) in 2013 and 0.53 cases per 100 person-years (95% CI: 0.0; 1.4) in 2018. The incidence decline among women aged 15-19 was -0.34 cases per 100 person-years (95% CI: -1.31;0.64).

Conclusions

The lack of evidence of incidence decline among adolescent girls is noteworthy and disconcerting. Our findings suggest that large-scale surveys should seriously consider focusing their resources on the core group of women aged 15-19 years.

Thetha Nami ngithethe nawe (Let's Talk): a stepped-wedge cluster randomised trial of social mobilisation by peer navigators into community-based sexual health and HIV care, including pre-exposure prophylaxis (PrEP), to reduce sexually transmissible HIV amongst young people in rural KwaZulu-Natal, South Africa

BACKGROUND

Antiretroviral therapy (ART) through universal test and treat (UTT) and HIV pre-exposure prophylaxis (PrEP) substantially reduces HIV-related mortality and incidence. Effective ART based prevention has not translated into population-level impact in southern Africa due to sub-optimal coverage among youth. We aim to investigate the effectiveness, implementation and cost effectiveness of peer-led social mobilisation into decentralised integrated HIV and sexual reproductive health (SRH) services amongst adolescents and young adults in KwaZulu-Natal (KZN).

METHODS

We are conducting a type 1a hybrid effectiveness/implementation study, with a cluster randomized stepped-wedge trial (SWT) to assess effectiveness and a realist process evaluation to assess implementation outcomes. The SWT will be conducted in 40 clusters in rural KZN over 45 months. Clusters will be randomly allocated to receive the intervention in period 1 (early) or period 2 (delayed). 1) Intervention arm: Resident peer navigators in each cluster will approach young men and women aged 15-30 years living in their cluster to conduct health, social and educational needs assessment and tailor psychosocial support and health promotion, peer mentorship, and facilitate referrals into nurse led mobile clinics that visit each cluster regularly to deliver integrated SRH and differentiated HIV prevention (HIV testing, UTT for those positive, and PrEP for those eligible and negative). Standard of Care is UTT and PrEP delivered to 15-30 year olds from control clusters through primary health clinics. There are 3 co-primary outcomes measured amongst cross sectional surveys of 15-30 year olds: 1) effectiveness of the intervention in reducing the prevalence of sexually transmissible HIV; 2) uptake of universal risk informed HIV prevention intervention; 3) cost of transmissible HIV infection averted. We will use a realist process evaluation to interrogate the extent to which the intervention components support demand, uptake, and retention in risk-differentiated biomedical HIV prevention.

DISCUSSION

The findings of this trial will be used by policy makers to optimize delivery of universal differentiated HIV prevention, including HIV pre-exposure prophylaxis through peer-led mobilisation into community-based integrated adolescent and youth friendly HIV and sexual and reproductive health care.

Fostering Access to PrEP Among Adolescent Girls and Young Women Aged 16 to 24 Years at High Risk of HIV Through the DREAMS Initiative in Four Districts in Zambia

Adolescent girls and young women (AGYW) in sub-Saharan Africa remain at high risk for HIV, yet limited data exist on implementation of HIV pre-exposure prophylaxis (PrEP) for this group. We examined PrEP uptake among AGYW using a retrospective cohort enrolled in the Determined Resilient Empowered AIDS-free Mentored Safe (DREAMS) initiative in Zambia between October 2020 and March 2022. Consent was obtained from eligible AGYW at substantial risk for HIV, and they voluntarily participated in PrEP. Multivariable logistic regression was used to examine factors associated with PrEP refills following initiation. Of 4,162 HIV-negative AGYW, 3,233 (77%) were at substantial risk and initiated on PrEP. Overall, 68% of AGYW had at least one refill, but this differed significantly by age group and district. DREAMS was successful at reaching AGYW with PrEP services. More evidence is needed to assess reasons for discontinuation and to improve persistence for those with sustained HIV risk.

Impact of DREAMS interventions on experiences of violence among adolescent girls and young women: Findings from population-based cohort studies in Kenya and South Africa

DREAMS aims to reduce HIV incidence among adolescent girls and young women (AGYW) by tackling drivers of HIV risk including gender-based violence. We evaluate the impact of DREAMS on recent experiences of violence perpetuated by men against AGYW. AGYW cohorts were randomly selected from demographic platforms in South Africa (rural KwaZulu-Natal) and Kenya (Nairobi informal settlements and rural Gem sub-county). AGYW aged 13-22 years were enrolled in 2017 (Nairobi, KwaZulu-Natal) or 2018 (Gem), with annual follow-up to 2019. We described proportions of AGYW who self-reported experiences of violence perpetrated by males in the 12 months preceding the interview, overall and by form (physical, sexual, emotional). We investigated associations with DREAMS (invitation to participate during 2017-2018) through multivariable propensity score-adjusted logistic regression and estimated the causal effect of DREAMS on experiences of violence, under counter-factual scenarios in which all versus no AGYW were DREAMS beneficiaries. Among 852, 1018 and 1712 AGYW followed-up in 2019 in Nairobi, Gem and KZN, respectively, proportions reporting any violence in 2019 were higher in Nairobi (29%) than Gem (18%) and KwaZulu-Natal (19%). By sub-type, emotional and physical violence were more frequently reported than sexual violence. We found no evidence of an impact attributable to DREAMS on overall levels of violence, in any setting. Nor was there evidence of impact on sub-types of violence, with one exception: an increase in physical violence in Nairobi if all, versus no, AGYW were DREAMS beneficiaries (16% vs 11%; +5% difference [95% CI: +0.2%, +10.0%]). Experiences of gender-based violence were common among AGYW, especially in urban settings, and DREAMS had no measurable impact on reducing violence within three years of implementation. Violence prevention programming that reaches more men and the broader community, sustained for longer periods, may yield greater gains in violence reduction than AGYW-focused programming. Additionally, more investment in implementation research is needed to bridge trial-based study findings from efficacy to population-level effectiveness.

Bottlenecks and Solutions During Implementation of the DREAMS Program for Adolescent Girls and Young Women in Namibia

BACKGROUND

We synthesize implementation bottlenecks experienced while implementing the DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe) program, an HIV prevention intervention for adolescent girls and young women (AGYW), in Namibia from 2017 to 2019. Bottlenecks were organized into the following 4 AGYW program components.

PROGRAM ACCESS

Enrollment was slowed by the time-intensive nature of screening and other baseline data collection requirements, delays in acquiring parental consent, and limited time for after-school activities. Solutions included obtaining advance consent and providing 1-stop service delivery and transportation assistance.

HEALTH EDUCATION

We experienced difficulty identifying safe spaces for AGYW to meet. A lack of tailored curricula also impeded activities. Governments, stakeholders, and partners can plan ahead to help DREAMS identify appropriate safe spaces. Curricula should be identified and adapted before implementation.

HEALTH SERVICES

Uneven availability of government-provided commodities (e.g., condoms, preexposure prophylaxis [PrEP], family planning products) and lack of AGYW-centered PrEP delivery approaches impacted services. Better forecasting of commodity needs and government commitment to supply chain strengthening will help ensure adequate program stock.

SOCIAL SERVICES

The availability of only centralized care following gender-based violence (GBV) and the limited number of government social workers to manage GBV cases constrained service provision. Triaging GBV cases-i.e., referring high-risk cases to government social workers and providing DREAMS-specific social services for other cases-can ensure proper caseload management.

CONCLUSION

These bottlenecks highlight practical implementation issues and higher-level considerations for AGYW-centered HIV prevention programs. The critical need for multilayered programming for HIV/GBV prevention in AGYW cannot be addressed simply with additional funds but requires multilevel collaboration and forecasting. The urgency to achieve results must be balanced with the need for adequate implementation preparedness.

Multisectoral, Combination HIV Prevention for Adolescent Girls and Young Women: A Qualitative Study of the DREAMS Implementation Trajectory in Zambia

OBJECTIVE

To identify solutions to the implementation challenges with the DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored, and Safe women) Partnership in Zambia, this study examines the rollout and evolution of the DREAMS Partnership's implementation.

METHODS

In September-October 2018, implementing partner (IP) staff (n=15) and adolescent girls and young women (AGYW) participating in DREAMS programming (n=32) completed in-depth interviews exploring early rollout and scale-up of DREAMS, experiences with program participation, and shifting service delivery approaches in response to emerging implementation challenges. Inductive and deductive thematic analysis of 47 interviews uncovered salient service delivery facilitators and barriers in the first 2 years of DREAMS implementation, which were subsequently mapped onto the following domains: reach, effectiveness, adoption, implementation, and maintenance.

RESULTS

Key implementation successes identified by IP staff included using standardized recruitment and risk assessment tools across IP organizations, using a mentor model for delivering program content to AGYW, and offering centralized service delivery at venues accessible to AGYW. Implementation challenges identified early in the DREAMS Partnership's lifecycle were rectified through adaptive service delivery strategies. Monthly in-person coordination meetings were established to resolve IP staff jurisdictional disputes over recruitment and target setting. To address high participant attrition, IP staff adopted a cohort approach to sequentially recruit AGYW who enrolled together and provided social support to one another to sustain involvement in DREAMS programming. Prominent barriers to implementation fidelity included challenges recruiting the highest-risk AGYW (e.g., those out of school), limited resources to incentivize participation by young women, and inadequate planning to facilitate absorption of individual DREAMS interventions by the public sector upon project conclusion.

CONCLUSIONS

Delivering multisectoral HIV prevention programs like DREAMS with fidelity requires a robust implementation infrastructure (e.g., adaptable workplans and harmonized record management systems), early coordination between IP organizations, and sustained financial commitments from donors.

Understanding older peoples' chronic disease self-management practices and challenges in the context of grandchildren caregiving: A qualitative study in rural KwaZulu-Natal, South Africa

While chronic diseases are amongst the major health burdens of older South Africans, the responsibilities of caring for grandchildren, by mostly grandmothers, may further affect older people's health and well-being. There is a paucity of information about chronic disease self-management for older people in the context of grandchildren caregiving in sub-Saharan Africa. Guided by the Self-Management Framework, the purpose of this qualitative methods study was to explore the chronic disease self-management practices and challenges of grandparent caregivers in rural KwaZulu-Natal, South Africa. Eighteen repeat in-depth interviews were carried out with six grandparent caregivers aged 56 to 80 years over 12 months. Thematic analysis was conducted based on the Self-Management Framework. Pathways into self-management of chronic illnesses were identified: living with a chronic illness, focusing on illness needs, and activating resources. Self-perceptions of caregiving dictated that grandmothers, as women, have the responsibility of caring for grandchildren when they themselves needed care, lived in poverty, and with chronic illnesses that require self-management. However, despite the hardship, the gendered role of caring for grandchildren brought meaning to the grandmothers' lives and supported self-management due to the reciprocal relationship with grandchildren, although chronic illness self-management was complicated where relationships between grandmothers and grandchildren were estranged. The study findings demonstrate that grandchildren caregiving and self-management of chronic conditions are inextricably linked. Optimal self-management of chronic diseases must be seen within a larger context that simultaneously addresses chronic diseases, while paying attention to the intersection of socio-cultural factors with self-management.

A qualitative investigation of facilitators and barriers to DREAMS uptake among adolescents with grandparent caregivers in rural KwaZulu-Natal, South Africa

Adolescents with grandparent caregivers have experienced challenges including the death of one or both parents due to HIV in sub-Saharan Africa. They may be left out of existing HIV prevention interventions targeting parents and children. We investigated the facilitators and barriers to DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored and Safe) programme uptake among adolescents with grandparent caregivers across different levels of the socio-ecological model in rural South Africa. Data were collected in three phases (October 2017 to September 2018). Adolescents (13-19 years old) and their grandparent caregivers (≥50 years old) (n = 12) contributed to repeat in-depth interviews to share their perceptions and experiences regarding adolescents' participation in DREAMS. Data were triangulated using key informant interviews with DREAMS intervention facilitators (n = 2) to give insights into their experiences of delivering DREAMS interventions. Written informed consent or child assent was obtained from all individuals before participation. All data were collected in isiZulu and audio-recorded, transcribed verbatim and translated into English. Thematic and dyadic analysis approaches were conducted guided by the socio-ecological model. Participation in DREAMS was most effective when DREAMS messaging reinforced existing norms around sex and sexuality and when the interventions improved care relationships between the adolescents and their older caregivers. DREAMS was less acceptable when it deviated from the norms, raised SRH information that conflicts with abstinence and virginity, and when youth empowerment was perceived as a potential threat to intergenerational power dynamics. While DREAMS was able to engage these complex families, there were failures, about factors uniquely critical to these families, such as in engaging children and carers with disabilities and failure to include adolescent boys in some interventions. There is a need to adapt HIV prevention interventions to tackle care relationships specific to adolescent-grandparent caregiver communication.

The impact of financial incentives on HIV incidence among adolescent girls and young women in Eswatini: Sitakhela Likusasa, a cluster randomised trial

INTRODUCTION

Incentives conditional on school attendance or on remaining free of sexually transmitted infections have produced mixed results in reducing HIV incidence.

METHODS

HIV-negative adolescent girls and young women aged 15-22%-50% of whom were out of school-were recruited from 293 clusters in Eswatini from urban (30%) and rural areas (70%).Financial incentives conditional on education attendance were randomly allocated at the cluster level. All participants were further individually randomised into eligibility for a raffle incentive conditional on random selection into the raffle, on negative tests for syphilis and Trichomonas vaginalis and on being a raffle winner, creating four subarms in a 2×2 factorial design: no-intervention, raffle incentive, education incentive and raffle & education incentive. Randomisation was unblinded to participants.Logistic regressions were used in intention-to-treat analysis of HIV incidence over 3 years to estimate the impact of incentives conditional on school attendance and raffle incentives conditional on remaining sexually transmitted infection free.

RESULTS

The study recruited 4389 HIV-negative participants, who were distributed into four subarms: no intervention (n=1068), raffle incentive (n=1162), education incentive (n=1088) and raffle and education incentive (n=1071).At endline, 272 participants from 3772 for whom endline data were collected, tested positive for HIV. HIV incidence among participants in education treatment arm was significantly lower than in the education control arm, 6.34% (119/1878) versus 8.08% (153/1894) (p=0.041); OR: 0.766 (0.598 to 0.981); adjusted OR (aOR): 0.754 (0.585 to 0.972). Compared with the no intervention subarm, HIV incidence in the raffle and education incentive subarm was significantly lower, 5.79% (54/878) versus 8.84% (80/905); OR: 0.634 (0.443 to 0.907); aOR: 0.622 (0.433 to 0.893), while it was not significantly lower in the raffle incentive subarm.

CONCLUSION

Financial incentives conditional on education participation significantly reduced HIV infection among adolescent girls and young women in Eswatini and appear to be a promising tool for prevention in high HIV prevalence settings.

Women's Perceptions of HIV- and Sexuality-Related Stigma in Relation to PrEP: Qualitative Findings from the Masibambane Study, Durban, South Africa

Daily oral pre-exposure prophylaxis (PrEP) offers effective HIV prevention. In South Africa, PrEP is publicly available, but use among young women remains low. We explored young women's perceptions of PrEP to inform a gender-focused intervention to promote PrEP uptake. Six focus group discussions and eight in-depth interviews exploring perceptions of PrEP were conducted with forty-six women not using PrEP, ages 18-25, from central Durban. Data were thematically analyzed using a team-based consensus approach. The study was conducted among likely PrEP users: women were highly-educated, with 84.8% enrolled in post-secondary education. Qualitative data revealed intersecting social stigmas related to HIV and women's sexuality. Women feared that daily PrEP pills would be confused with anti-retroviral treatment, creating vulnerability to misplaced HIV stigma. Women also anticipated that taking PrEP could expose them to assumptions of promiscuity from the community. To address these anticipated community-level reactions, women suggested community-facing interventions to reduce the burden on young women considering PrEP. Concerns around PrEP use in this group of urban, educated women reflects layered stigmas that may inhibit future PrEP use. Stigma-reducing strategies, such as media campaigns and educational interventions directed at communities who could benefit from PrEP, should re-frame PrEP as an empowering and responsible choice for young women.

Age-Restriction of a Validated Risk Scoring Tool Better Predicts HIV Acquisition in South African Women: CAPRISA 004

We examined the predictive ability of the VOICE risk screening tool among adolescent girls and young women at heightened HIV risk in urban and peri-urban Kwa-Zulu-Natal, South Africa. Using participant data from CAPRISA 004’s control arm (N = 444), we applied the initial VOICE risk screening score (IRS), a modified risk score (MRS) based on predictive and non-predictive variables in our data, and age-restricted (AIRS and AMRS, respectively). We estimated incidence rates, 95% confidence bounds, sensitivity, specificity, negative and positive predictive values and area under the curve (AUC). The sample’s HIV incidence rate was 9.1/100 Person-Years [95% CI 6.9–11.7], resulting from 60 seroconversions (60/660.7 Person-Years). The IRS’ ≥ 8 cutpoint produced moderate discrimination [AUC = 0.66 (0.54–0.74), sensitivity = 63%, specificity = 57%]. Restricting to age < 25 years improved the score’s predictive ability (AIRS: AUC = 0.69, AMRS: AUC = 0.70), owing mainly to male partner having other partners and HSV-2. The risk tool predicted HIV acquisition at a higher cutpoint in this sample than in the initial VOICE analysis. After age-stratification, fewer variables were needed for maintaining score’s predictiveness. In this high incidence setting, risk screening may still improve the efficiency or effectiveness of prevention counseling services. However, PrEP should be offered to all prevention-seeking individuals, regardless of risk ascertainment.

Isisekelo Sempilo study protocol for the effectiveness of HIV prevention embedded in sexual health with or without peer navigator support (Thetha Nami) to reduce prevalence of transmissible HIV amongst adolescents and young adults in rural KwaZulu-Natal: a 2 × 2 factorial randomised controlled trial

Background

Antiretroviral therapy (ART) through universal test and treat (UTT) and HIV pre-exposure prophylaxis (PrEP) substantially reduces HIV-related mortality, morbidity and incidence. Effective individual-level prevention modalities have not translated into population-level impact in southern Africa due to sub-optimal coverage among adolescents and youth who are hard to engage. We aim to investigate the feasibility, acceptability, and preliminary population level effectiveness of HIV prevention services with or without peer support to reduce prevalence of transmissible HIV amongst adolescents and young adults in KwaZulu-Natal.

Methods

We are conducting a 2 × 2 factorial trial among young men and women aged 16–29 years, randomly selected from the Africa Health Research Institute demographic surveillance area. Participants are randomly allocated to one of four intervention combinations: 1) Standard of Care (SOC): nurse-led services for HIV testing plus ART if positive or PrEP for those eligible and negative; 2) Sexual and Reproductive Health (SRH): Baseline self-collected vaginal and urine samples with study-organized clinic appointments for results, treatment and delivery of HIV testing, ART and PrEP integrated with SRH services; 3) Peer-support: Study referral of participants to a peer navigator to assess their health, social and educational needs and provide risk-informed HIV prevention, including facilitating clinic attendance; or 4) SRH + peer-support.

The primary outcomes for effectiveness are: (1) the proportion of individuals with infectious HIV at 12 months and (2) uptake of risk-informed comprehensive HIV prevention services within 60 days of enrolment. At 12 months, all participants will be contacted at home and the study team will collect a dried blood spot for HIV ELISA and HIV viral load testing.

Discussion

This trial will enable us to understand the relative importance of SRH and peer support in creating demand for effective and risk informed biomedical HIV prevention and preliminary data on their effectiveness on reducing the prevalence of transmissible HIV amongst all adolescents and youth.

Girl Champ in eSwatini: A Strategic Marketing Campaign to Promote Demand for Sexual and Reproductive Health Services Among Young Women

Efforts to engage adolescent girls and young women (AGYW) in HIV services have struggled, in part, due to limited awareness of services and stigma. Strategic marketing is a promising approach, but the impact on youth behavior change is unclear. We report findings from a mixed methods evaluation of the Girl Champ campaign, designed to generate demand for sexual and reproductive services among AGYW, and piloted in three clinics in the Manzini region of eSwatini. We analyzed and integrated data from longitudinal, clinic-level databases on health service utilization among AGYW before and after the pilot, qualitative interviews with stakeholders responsible for the implementation of the pilot, and participant feedback surveys from attendees of Girl Champ events. Girl Champ was well received by most stakeholders based on event attendance and participant feedback, and associated with longitudinal improvements in demand for HIV services. Findings can inform future HIV demand creation interventions for youth.

Thetha Nami: participatory development of a peer-navigator intervention to deliver biosocial HIV prevention for adolescents and youth in rural South Africa

BACKGROUND

Despite effective biomedical tools, HIV remains the largest cause of morbidity/mortality in South Africa - especially among adolescents and young people. We used community-based participatory research (CBPR), informed by principles of social justice, to develop a peer-led biosocial intervention for HIV prevention in KwaZulu-Natal (KZN).

METHODS

Between March 2018 and September 2019 we used CBPR to iteratively co-create and contextually adapt a biosocial peer-led intervention to support HIV prevention. Men and women aged 18-30 years were selected by community leaders of 21 intervention implementation areas (izigodi) and underwent 20 weeks of training as peer-navigators. We synthesised quantitative and qualitative data collected during a 2016-2018 study into 17 vignettes illustrating the local drivers of HIV. During three participatory intervention development workshops and community mapping sessions, the peer-navigators critically engaged with vignettes, brainstormed solutions and mapped the components to their own izigodi. The intervention components were plotted to a Theory of Change which, following a six-month pilot and process evaluation, the peer-navigators refined. The intervention will be evaluated in a randomised controlled trial ( NCT04532307 ).

RESULTS

Following written and oral assessments, 57 of the 108 initially selected participated in two workshops to discuss the vignettes and co-create the Thetha Nami (`talk to me'). The intervention included peer-led health promotion to improve self-efficacy and demand for HIV prevention, referrals to social and educational resources, and aaccessible youth-friendly clinical services to improve uptake of HIV prevention. During the pilot the peer-navigators approached 6871 young people, of whom 6141 (89%) accepted health promotion and 438 were linked to care. During semi-structured interviews peer-navigators described the appeal of providing sexual health information to peers of a similar age and background but wanted to provide more than just "onward referral". In the third participatory workshop 54 peer-navigators refined the Thetha Nami intervention to add three components: structured assessment tool to tailor health promotion and referrals, safe spaces and community advocacy to create an enabling environment, and peer-mentorship and navigation of resources to improve retention in HIV prevention.

CONCLUSION

Local youth were able to use evidence to develop a contextually adapted peer-led intervention to deliver biosocial HIV prevention.

Effect of peer-distributed HIV self-test kits on demand for biomedical HIV prevention in rural KwaZulu-Natal, South Africa: a three-armed cluster-randomised trial comparing social networks versus direct delivery

STUDY OBJECTIVE

We investigated two peer distribution models of HIV self-testing (HIVST) in HIV prevention demand creation compared with trained young community members (peer navigators).

METHODS

We used restricted randomisation to allocate 24 peer navigator pairs (clusters) in KwaZulu-Natal 1:1:1: (1) standard of care (SOC): peer navigators distributed clinic referrals, pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART) information to 18-30 year olds. (2) peer navigator direct distribution (PND): Peer navigators distributed HIVST packs (SOC plus two OraQuick HIVST kits) (3) incentivised peer networks (IPN): peer navigators recruited young community members (seeds) to distribute up to five HIVST packs to 18-30 year olds within their social networks. Seeds received 20 Rand (US$1.5) for each recipient who distributed further packs. The primary outcome was PrEP/ART linkage, defined as screening for PrEP/ART eligibility within 90 days of pack distribution per peer navigator month (pnm) of outreach, in women aged 18-24 (a priority for HIV prevention). Investigators and statisticians were blinded to allocation. Analysis was intention to treat. Total and unit costs were collected prospectively.

RESULTS

Between March and December 2019, 4163 packs (1098 SOC, 1480 PND, 1585 IPN) were distributed across 24 clusters. During 144 pnm, 272 18-30 year olds linked to PrEP/ART (1.9/pnm). Linkage rates for 18-24-year-old women were lower for IPN (n=26, 0.54/pnm) than PND (n=45, 0.80/pnm; SOC n=49, 0.85/pnm). Rate ratios were 0.68 (95% CI 0.28 to 1.66) for IPN versus PND, 0.64 (95% CI 0.26 to 1.62) for IPN versus SOC and 0.95 (95% CI 0.38 to 2.36) for PND versus SOC. In 18-30 year olds, PND had significantly more linkages than IPN (2.11 vs 0.88/pnm, RR 0.42, 95% CI 0.18 to 0.98). Cost per pack distributed was cheapest for IPN (US$36) c.f. SOC (US$64). Cost per person linked to PrEP/ART was cheaper in both peer navigator arms compared with IPN.

DISCUSSION

HIVST did not increase demand for PrEP/ART. Incentivised social network distribution reached large numbers with HIVST but resulted in fewer linkages compared with PrEP/ART promotion by peer navigators.

Facilitators and barriers to HIV pre-exposure prophylaxis (PrEP) uptake through a community-based intervention strategy among adolescent girls and young women in Seme Sub-County, Kisumu, Kenya

BACKGROUND

While the introduction of HIV Pre-Exposure Prophylaxis (PrEP) as an HIV prevention strategy has allowed women to exercise more control over the reduction of HIV transmission rates, adolescent girls and young women in Sub-Saharan Africa continue to experience higher rates of HIV infections and bear the greatest disease burden. Understanding progress in PrEP uptake among adolescent girls and young women would enhance risk reduction in this vulnerable population. The Determined, Resilient, AIDS-Free, Mentored and Safe women (DREAMS) Initiative plays a key role in this risk reduction strategy.

METHODS

We performed a qualitative study to explore facilitators and barriers to PrEP implementation and assess factors effecting initiation and persistence on PrEP among adolescent girls and young women enrolled in the DREAMS Initiative at Pamoja Community Based Organization in Kisumu, Kenya. We conducted key informant interviews (n = 15) with Pamoja Community Based Organization staff, health care providers and community leaders. Additionally, we conducted focus group discussions with young women receiving PrEP and peer mentors (n = 40). We performed a directed content analysis using the Consolidated Framework for Implementation Research to organize the identified facilitators and barriers.

RESULTS

We found that the use of the safe space model, decentralization of PrEP support and delivery, peer mentors, effective linkage to local health care facilities, the sensitization of parents and male sexual partners, disclosure of PrEP use by beneficiaries, active stakeholder involvement and community engagement were among some of the facilitators to PrEP uptake. Barriers to PrEP implementation, initiation and persistence included stigma associated with the use of anti-retroviral drugs, drug side effects, frequent relocation of beneficiaries, limited resources for routine screening and medication monitoring, and a limited number of qualified health care workers for PrEP distribution and administration.

CONCLUSION

Overall, the community roll-out of PrEP within the DREAMS Initiative was successful due to a number of key facilitating factors, which ultimately led to successful PrEP implementation, increased PrEP initiation and enhanced persistence among adolescent girls and young women. The identified barriers should be addressed so that a larger scale-up of PrEP roll-out is possible in the future.

Reaching early adolescents with a complex intervention for HIV prevention: findings from a cohort study to evaluate DREAMS in two informal settlements in Nairobi, Kenya

BACKGROUND

The DREAMS Partnership promotes combination HIV prevention among adolescent girls and young women. We examined the extent to which DREAMS interventions reached early adolescent girls (EAG; aged 10-14 years) in two informal settlements in Nairobi, and the characteristics of those reached, after 3 years of implementation.

METHODS

We utilized three data rounds from a randomly-sampled cohort of EAG established in 2017 in Korogocho and Viwandani informal settlements where DREAMS interventions were implemented. Interventions were classified as individual or contextual-level, with individual interventions further categorised as primary (prioritised for this age group), or secondary. We summarised self-reported invitation to participate in DREAMS, and uptake of eight interventions that were supported by DREAMS, during 2017-2019. Multivariable logistic regression analysis was used to identify individual and household characteristics associated with invitation to DREAMS and uptake of primary interventions.

RESULTS

Data were available for 606, 516 (retention rate of 85%) and 494 (82%) EAG in 2017, 2018 and 2019, respectively. Proportions invited to DREAMS increased from 49% in 2017, to 77% by 2018, and to 88% by 2019. School-based HIV and violence prevention, and HIV testing and counselling were the most accessed interventions (both at 82%). Cumulative uptake of interventions was higher among those invited to participate in DREAMS compared to those never invited, particularly for new interventions such as social asset building and financial capability training. Contextual-level interventions were accessed infrequently. Most of those invited both in 2017 and 2018 accessed ≥3 interventions (96%), and 55% received all three primary interventions by 2019.

CONCLUSIONS

Uptake of DREAMS interventions among a representative sample of EAG was high and quickly increased over the implementation period. The majority accessed multiple interventions, indicating that it is feasible to integrate and deliver a package of interventions to EAG in a challenging informal context.

Young people's experiences of sexual and reproductive health interventions in rural KwaZulu-Natal, South Africa

Despite efforts to address HIV-infection, adolescents and young peoples' (AYP) engagement in interventions remains suboptimal. Guided by a risk protection framework we describe factors that support positive and negative experiences of HIV and SRH interventions among AYP in rural KwaZulu-Natal, South Africa, using data from: community mapping; repeat semi-structured individual interviews (n= 58 in 2017, n=50 in 2018, n=37 in 2019-2020); and group discussions (n=13). AYP who had appropriate and accurate HIV-and SRH-related information were reported to use health care services. Responsive health care workers, good family and peer relationships were seen to be protective through building close connections and improving self-efficacy to access care. In contrast to cross-generational relationships with men, alcohol and drug use and early pregnancy were seen to put AYP at risk. Policies and interventions are needed that promote stable and supportive relationships with caregivers and peers, positive social norms and non-judgemental behaviour within clinical services.
