Associations Between Healthcare Discrimination, Medical Mistrust, and Covid-19 Vaccine Uptake Among Young Black Adults in the Southern United States
Racial inequities related to COVID-19 exposure, morbidity, mortality, and access to care in the United States (U.S.) are notable, and COVID-19 vaccine uptake is lower among Black Americans than White Americans. Yet, mechanisms linking healthcare experiences to COVID-19 vaccination behavior among young adults are not well characterized. We analyzed cross-sectional data collected between March and June 2023 from 360 Black young adults (ages 18–29) …
Uptake of HIV Self-testing Among Adolescents and Young Adults in Nigeria
Postpartum Intrauterine Device Removal and Access to Removal in the 18 Months Following an Intervention in Tanzania, Sri Lanka, and Nepal
Family planning programs in the Global South promote long‐acting reversible contraception (LARC), but research suggests that women face barriers to LARC discontinuation, inhibiting their reproductive autonomy. Scholars have called for improved data visibility around LARC removal access. We use data from the Postpartum Intrauterine Device (PPIUD) Study, a randomized trial of a PPIUD intervention conducted in Nepal, Sri Lanka, and Tanzania from 201…
Trajectories and predictors of HIV care retention among individuals receiving ART in rural South Africa
Background: Successful retention in care of people living with HIV remains a challenge and a cornerstone of ending the epidemic. A better understanding of retention predictors could guide an evidence-based approach to target interventions. We sought to characterise HIV care retention trajectories among individuals receiving antiretroviral therapy (ART) in a rural South Africa setting, and to determine factors associated with those trajectories. M…
Relationships Between Vaccine Knowledge, Hesitancy, and Conspiracy Beliefs on Covid-19, Influenza, and HPV Vaccination
Comparing youth-friendly clinics to the standard of care for adolescent girls and young women in Malawi
Adolescent girls and young women (AGYW) in sub-Saharan Africa (SSA) face difficulties accessing sexual and reproductive health (SRH) services. Youth-friendly service delivery models may prove an alternative to increase SRH service uptake. This analysis utilises evidence from the Girl Power-Malawi study, a study designed to compare the impact of different models of service delivery on SRH service uptake for AGYW. Three intervention clinics trained…
Assessing the Effect of the Covid-19 Pandemic on Abortion Care Utilization and Delays and Whether There Was a Differential Impact Among Latinas in North Carolina
The COVID-19 pandemic was associated with an increase in monthly abortion counts through 2021 and a decrease in the proportion of abortions after the first trimester at the pandemic's onset
Stress-responsive biomarkers and sexual behaviors among young women in rural South Africa
BACKGROUND: Adolescence is a critical period when youth develop their decision-making skills and may engage in their first sexual encounters. Stress during this time can affect decision making; however, limited research has examined the relationship between biological stress correlates and sexual behavior among adolescent girls and young women (AGYW) in high-HIV incidence areas. PURPOSE: To examine whether stress-responsive biomarkers are longitu…
Trajectories of intimate partner violence and their relationship to stress among young women in South Africa
BACKGROUND: One in four South African women will experience intimate partner violence (IPV) in their lifetime, potentially increasing their biological stress. In South Africa, limited IPV and stress research has utilized multiple timepoints or examined modifying factors. Cash transfers (CTs) are associated with reduced IPV and stress and may be an intervention target. AIMS: We used data-driven methods to identify longitudinal IPV trajectory group…

Developmental Trajectories of Transactional Sex and Age-Disparate Relationships During Adolescence
Assessing the durability of a cash transfer on physical intimate partner violence and sexual relationships among adolescent girls and young women in rural South Africa
The cash transfer reduced AGYW's risk of IPV, though effects were attenuated after the cash ended. Provision of cash during adolescence - a period when AGYW are highly susceptible to IPV and HIV - may empower them in their current relationship and yield long term health benefits
Clinic presentation delay and tuberculosis treatment outcomes in the Lake Victoria region of East Africa
In the Lake Victoria region of East Africa, little is known about delays between tuberculosis (TB) symptom onset and presentation at a clinic. Associations between clinic presentation delay and TB treatment outcomes are also poorly understood. In 2019, we abstracted data from routine TB treatment records for all adults (n = 776) initiating TB treatment in a 6-month period across 12 health facilities near Lake Victoria. We interviewed 301 cohort m…
Geographic mobility and treatment outcomes among people in care for tuberculosis in the Lake Victoria region of East Africa
Geographic mobility may disrupt continuity of care and contribute to poor clinical outcomes among people receiving treatment for tuberculosis (TB). This may occur especially where health services are not well coordinated across international borders, particularly in lower and middle income country settings. In this work, we describe mobility and the relationship between mobility and unfavorable TB treatment outcomes (i.e., death, loss to follow-u…
Exploring the relationship between anticipated stigma and community shared concerns about HIV on defaulting from HIV care in rural South Africa
In this sample, we found limited impact of reducing anticipated stigma and increasing shared concern about HIV on retention in care. Future studies should consider the limitations of this study by examining the influence of other sources of stigma in more detail and assessing how perceptions of stigma and concern impact the full HIV testing and care cascade
Intimate partner violence is associated with cytomegalovirus among young women in rural South Africa
Stressful life circumstances (e.g. violence and poverty) have been associated with elevated biomarkers, including C-reactive protein (CRP), cytomegalovirus (CMV), and herpes simplex virus type-1 (HSV-1), among older adults in high-income settings. Yet, it remains unknown whether these relationships exist among younger populations in resource-limited settings. We therefore utilised a cohort of 1,279 adolescent girls and young women (AGYW) from the…
The use of monitoring data and community feedback mechanisms to increase HIV testing among men during a cluster-randomised community mobilisation trial in South Africa
This short communication describes the development and implementation of a programme monitoring and feedback process during a cluster-randomised community mobilisation intervention conducted in rural Bushbuckridge, Mpumalanga, South Africa. Intervention activities took place from August 2015 to July 2018 with the aim of addressing social barriers to HIV counselling and testing and engagement in HIV care, with a specific focus on reaching men. Mul…
Associations between psychosocial wellbeing and experience of gender-based violence at community, household, and intimate-partner levels among a cross-sectional cohort of young people living with and …
Findings suggest that for young people in this setting, GBV at community and household levels was more prevalent during COVID-19 compared to IPV, especially for YPLWoH. While we found limited associations between COVID-related stressors and GBV, the perceived increases in GBV since lockdown in a setting where GBV is endemic, and the association of household violence with mental health, is a concern for future pandemic responses and should be long…
Understanding the effects of universal test and treat on longitudinal HIV care outcomes among South African youth
Implementation of UTT yielded modest improvements in time spent on ART and virally suppressed among South African YLHIV- however, meeting UNAIDS' 95-95-95 targets remains a challenge. Retention in care and re-engagement interventions that can be implemented between diagnosis and linkage to care and between ART initiation and viral suppression (e.g., longitudinal counseling) may be particularly important to improving care outcomes among South Afri…

The impact of a randomized cash transfer intervention on mortality of adult household members in rural South Africa, 2011-2022
Access to Social Protection by People Living with, at Risk of, or Affected by HIV in Eswatini, Malawi, Tanzania, and Zambia
We aimed to measure social protection coverage among the general population, women and men living with HIV (WLHIV, MLHV), female and male sex workers (FSW, MSW), men who have sex with men (MSM), adolescent girls young women (AGYW), and orphans vulnerable children (OVC) in Eswatini, Malawi, Tanzania, and Zambia. We used Population-Based HIV Impact Assessment data. We operationalised social protection benefits as external economic support from priv…
Covid-19 vaccine hesitancy in rural South Africa
Background: To date, COVID-19 vaccine coverage in the African region falls far too short of global goals. Increasing vaccination rates requires understanding barriers to vaccination so that effective interventions that sensitively and effectively address barriers to vaccination can be implemented. Methods: To assess COVID-19 vaccination levels and identify major barriers to vaccine uptake we conducted a population-based, cross-sectional survey am…
The impact of conditional cash transfers for HIV prevention on peer relationships
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 …

Orphanhood and Completion of Compulsory School Education Among Young People in South Africa
We examined the association of orphanhood and completion of compulsory school education among young people in South Africa. In South Africa, school attendance is compulsory through grade 9, which should be completed before age 16. However, family and social factors such as orphanhood and poverty can hinder educational attainment. Participants were 10,452 16–24‐year‐olds who completed a South African national representative household survey. Overa…
The Impact of a Conditional Cash Transfer on Multidimensional Deprivation of Young Women
Despite the growing popularity of multidimensional poverty measurement and analysis, its use to measure the impact of social protection programs remains scarce. Using primary data collected for the evaluation of HIV Prevention Trials Network (HPTN) 068, a randomized, conditional cash transfer intervention for young girls in South Africa that ran from 2011 to 2015, we construct an individual-level measure of multidimensional poverty, a major depar…

Working with public sector clinics to provide adolescent-friendly services in South Africa
Health care facilities can play an important role for adolescents in preventing health problems, in promoting sexual and reproductive health and in shaping positive behaviours. Extensive research has established that South African public health facilities are failing to provide adolescent-friendly health services. The National Adolescent-Friendly Clinic Initiative (NAFCI) is an accreditation programme designed to improve the quality of adolescent…
Health Care Providers' Challenges to High-Quality HIV Care and Antiretroviral Treatment Retention in Rural South Africa
Provision of high-quality HIV care is challenging, especially in rural primary care clinics in high HIV burden settings. We aimed to better understand the main challenges to quality HIV care provision and retention in antiretroviral treatment (ART) programs in rural South Africa from the health care providers' perspective. We conducted semi-structured qualitative interviews with 23 providers from nine rural clinics. Using thematic and framework a…
Investments in children’s health and the Kenyan cash transfer for orphans and vulnerable children
Child mortality is one of the most pressing global health and policy issues in the developing world. The leading drivers of death-pneumonia, diarrhea and malaria-are preventable and treatable. However, these illnesses are exacerbated by a lack of accessible nutrition, water, basic and preventive health services, and sanitary living conditions-all factors which are more likely to disproportionately impact the poor. We examine whether Kenya's large…
Collective efficacy, alcohol outlet density, and young men’s alcohol use in rural South Africa
Alcohol use contributes to morbidity and mortality in developing countries by increasing the risk of trauma and disease, including alcohol dependence. Limited research addresses determinants of alcohol use beyond the individual level in sub-Saharan Africa. We test the association of community collective efficacy and alcohol outlet density with young men's drinking in a cross-sectional, locally representative survey conducted in rural northeast So…
Sexual Violence and Reproductive Health Outcomes Among South African Female Youths
Objectives. We studied whether female youths from communities with higher sexual violence were at greater risk of negative reproductive health outcomes. Methods. We used data from a 2003 nationally representative household survey of youths aged 15–24 years in South Africa. The key independent variable was whether a woman had ever been threatened or forced to have sex. We aggregated this variable to the community level to determine, with control f…
Contraceptive Conversations among Adolescent Girls and Young Women and Their Partners, Peers, and Older Female Family Members in Lilongwe, Malawi
In sub‐Saharan Africa, adolescent girls and young women (AGYW) have high levels of unmet need for contraception, particularly those who are unmarried or nulliparous. Conversations with partners, peers, and family members influence AGYW contraceptive decision‐making yet little is known about conversation content and impact or how they vary by relationship status and parity. This paper draws on qualitative data from 60 AGYW (aged 15–24) participati…
Terms Used for People Living With HIV in the Democratic Republic of the Congo
For this study we conducted in-depth interviews with 29 youth living with HIV (YLWH) and key informant interviews with 8 HIV care/support providers. We describe terms used to portray people living with HIV (PLWH) in Kinshasa, Democratic Republic of the Congo. Labels commonly used, mostly derogatory, described PLWH as walking corpses, dangers to others, or people deserving to die before others get infected. Blame and other accusations were directe…
Glen or Glenda
Objectives. We assessed agreement of reported gender of sex partners in 2 statewide HIV databases linked by client identifiers. Methods. Counseling, testing, and referral (CTR) records on all men aged 18 to 30 years who tested newly positive for HIV in North Carolina between 2000 and 2005 were matched to data abstracted from partner counseling and referral services (PCRS) records.

The Acceptability of Reuse of the Female Condom Among Urban South African Women
Working with public sector clinics to provide adolescent-friendly services in South Africa
Health care facilities can play an important role for adolescents in preventing health problems, in promoting sexual and reproductive health and in shaping positive behaviours. Extensive research has established that South African public health facilities are failing to provide adolescent-friendly health services. The National Adolescent-Friendly Clinic Initiative (NAFCI) is an accreditation programme designed to improve the quality of adolescent…
Sexual Power and HIV Risk, South Africa1
Gender power inequities are believed to play a key role in the HIV epidemic through their effects on women's power in sexual relationships. We hypothesized that lack of sexual power, measured with a four-point relationship control scale and by a woman's experience of forced sex with her most recent partner, would decrease the likelihood of consistent condom use and increase the risk for HIV infection among sexually experienced, 15- to 24-year-old…
