Development of a Self-administered Sexual Behavior Assessment Tool to Facilitate Self-reflection by Young Women in South Africa About HIV/STI Risk
Self-assessment of sexual behavior may empower adolescent girls and young women (AGYW) to reflect on HIV/STI risk and adopt prevention strategies. We developed a web-based sexual behavior self-assessment tool providing real-time feedback based on a numeric score and examined associations of scores with STI detection and HIV pre-exposure prophylaxis (PrEP) initiation among AGYW in South Africa. The tool was implemented as part of PALESA, a pilot r…
Perceptions About the Relationship Between HIV, Antiretroviral Therapy (ART), and Fecundity in Sub-Saharan Africa
Advances in antiretroviral therapy (ART) enable women living with HIV to safely conceive and give birth without vertical transmission. However, in sub-Saharan Africa, 1 in 6 people experience infertility and women living with HIV face even higher rates. Research shows that ART and virologic suppression improve fertility/fecundity, yet this benefit is often overlooked in ART adherence education. To map the literature on people’s understandings and…
Acceptability of an Integrated Model of Mental Health and PrEP Service Delivery for South African Adolescent Girls
Adolescent girls and young women (AGYW) at elevated HIV risk often experience common mental disorders (CMD), which are linked to lower PrEP adherence. We piloted a CMD intervention, the Youth Friendship Bench SA (YFB), and delivered alongside PrEP to improve CMD symptoms and PrEP adherence among South African AGYW. From April 2023-February 2024, 116 AGYW (18-25 years) with CMD symptoms were randomized to YFB plus standard of care (SOC) or SOC alo…
Acceptability and feasibility of a urine-based tenofovir adherence assay for monitoring and providing feedback on PrEP adherence in Kenya
Objective measures of oral PrEP adherence - especially point-of-care (POC) measures that enable real-time assessment, intervention, and feedback - have the potential to improve adherence. Our team previously developed and validated a novel urine-based POC metric of PrEP adherence. In this study, we sought to determine whether this assay is acceptable and feasible among women taking PrEP and PrEP providers in Kenya. We conducted a trial comparing …
Motivations for Starting and Stopping PrEP
Oral PrEP effectiveness depends on consistent use during periods of potential HIV exposure, but adolescent girls and young women (AGYW) find this challenging. Data on PrEP use decision-making and alignment with risk among AGYW are limited. From 2016 to 2018, we conducted in-depth interviews with participants in HPTN 082, an open-label PrEP study in South Africa and Zimbabwe, to explore reasons for PrEP starts, stops, and restarts. Of 60 PrEP acce…
Stakeholder Perspectives on a Community-Based Peer-Led Biomedical HIV Prevention Intervention for Women Who Engage in Sex Work in Southwestern Uganda
HIV prevalence among Ugandan women who engage in sex work (WESW) is 31%, yet uptake of oral pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) is suboptimal due to multiple factors, including stigma and barriers to accessing healthcare. "Peer mentors" (peer leaders within WESW networks) could facilitate community-based delivery of biomedical HIV prevention products for WESW. We conducted formative research with key stakeholders t…
The Association Between Use of Adherence Support Interventions and Adherence to HIV Preexposure Prophylaxis Among Young South African and Zimbabwean Women in HPTN 082
We assessed the association between PrEP adherence support interventions and intracellular tenofovir-diphosphate (TFV-DP) levels, a biomarker for PrEP adherence, using data from 368 South African and Zimbabwean adolescent girls and young women enrolled in the HIV Prevention Trials Network 082 trial from 2016 to 2018. Group-based trajectory modeling identified trajectories of TFV-DP levels and adherence support interventions, including weekly two-…
Acceptability and Feasibility of Remote PrEP Visits for Adolescent Girls and Young Women in South Africa
An Application of Evidence‐Based Approaches to Engage Young People in the Design of a Global Mental Health Databank
INTRODUCTION: Engaging youth in mental health research and intervention design has the potential to improve their relevance and effectiveness. Frameworks like Roger Hart's ladder of participation, Shier's pathways to participation and Lundy's voice and influence model aim to balance power between youth and adults. Hart's Ladder, specifically, is underutilized in global mental health research, presenting new opportunities to examine power dynamics…
Acceptability of an automated directly observed therapy (DOT) application for PrEP adherence support among young men who have sex with men
Pre-exposure prophylaxis (PrEP) adherence remains a challenge among young men who have sex with men (MSM). We developed and tested a smartphone application (“app”), “DOT Diary”, which combines automated directly observed therapy (DOT) with information about PrEP protection levels, pill-taking reminders, a sexual behavior diary, and a PrEP dosing calendar. To contextualize trial results, we qualitatively explored participants’ app experiences. The…
Hoping to Adhere? Examining the Relationship Between Hope and Pre-exposure Prophylaxis Willingness, Adherence, and Persistence Among Young Women in South Africa and Zimbabwe (HPTN 082)
Hope is a powerful psychological construct which is linked to positive health. Greater hope is associated with improved antiretroviral therapy adherence; however, less is known about the impact of hope on oral pre-exposure prophylaxis (PrEP) outcomes. HIV Prevention Trials Network 082, was an open-label PrEP study among young women (ages 16-25) in South Africa and Zimbabwe. Hope was measured at baseline and follow-up using a subset of the Hope fo…
Higher rates of mental health screening of adolescents recorded after provider training using simulated patients in a Kenyan HIV clinic
Background Kenyan adolescent girls and young women (AGYW) experience a dual burden of HIV and common mental disorders (CMD). HIV clinics are a key entry point for AGYW in need of integrated CMD and HIV care; however, rates of screening and referral for CMDs are low. Our objective was to test an evidence-based provider training strategy, simulated patient encounters (SPEs), on CMD service delivery for AGYW in a Kenyan HIV clinic. Methods This pilo…

Perinatal Depressive Symptoms and Viral Non-suppression Among a Prospective Cohort of Pregnant Women Living with HIV in Nigeria, Kenya, Uganda, and Tanzania
Depression is common during pregnancy and is associated with reduced adherence to HIV-related care, though little is known about perinatal trajectories of depression and viral suppression among women living with HIV (WLHV) in sub-Saharan Africa. We sought to assess any association between perinatal depressive symptoms and viral non-suppression among WLWH. Depressive symptomatology and viral load data were collected every 6 months from WLWH enroll…

HIV-Risk Behaviors and Social Support Among Men and Women Attending Alcohol-Serving Venues in South Africa
HIV/Aids-related stigma in South African alcohol-serving venues and its potential impact on HIV disclosure, testing and treatment-seeking behaviours
Alcohol-serving venues in South Africa are sites for high-risk behaviours that may lead to HIV transmission. Prevention and treatment interventions are sorely needed in these settings, but HIV-related stigma may limit their effectiveness. This study explored expressions of stigma among alcohol-serving venue patrons in Cape Town and examined the potential impact of stigma on HIV disclosure, testing and treatment-seeking behaviours. A total of 92 i…
