Article Synopsis
  • - This study investigates the impact of social protection, specifically government cash transfers and food security, on the health and well-being of adolescents living with HIV (ALHIV) in South Africa, focusing on achieving Global AIDS Targets like ART adherence, viral suppression, and reduced stigma.
  • - Over four years, researchers collected data from 1,046 ALHIV, examining factors such as ART adherence, sexual behavior, and stigma, while using advanced regression models to analyze outcomes related to cash transfers and food security.
  • - Results showed that receiving cash transfers and having food security were linked to better ART adherence and viral suppression, delayed sexual debut or consistent condom use, and lower enacted stigma among ALHIV, highlighting the importance of social support in

Background: Compared with other age groups, adolescents living with HIV (ALHIV) are estimated to have lower levels of adherence to antiretroviral treatment. Despite this, we lack evidence on adolescents' adherence patterns over time to inform the customization of intervention strategies.

Setting: Eastern Cape province, South Africa.

Introduction: Adolescent girls and young women (AGYW) living with HIV experience poor HIV outcomes and high rates of unintended pregnancy. Little is known about which healthcare provisions can optimize their HIV-related outcomes, particularly among AGYW mothers.

Methods: Eligible 12- to 24-year-old AGYW living with HIV from 61 health facilities in a South African district completed a survey in 2018-2019 (90% recruited).

Brief tools are necessary to identify adolescents at greatest risk for ART non-adherence. From the WHO's HEADSS/HEADSS+ adolescent wellbeing checklists, we identify constructs strongly associated with non-adherence (validated with viral load). We conducted interviews and collected clinical records from a 3-year cohort of 1046 adolescents living with HIV from 52 South African government facilities.

The timely identification of ART non-adherence among adolescents living with HIV presents a significant challenge, particularly in resource-limited settings where virologic monitoring is suboptimal. Using South African adolescent cohort data (N = 933, mean age 13.6 ± 2.

Adolescents living with HIV (ALHIV) face unique treatment and care challenges which may differ by how they acquired HIV, whether vertically (in-utero, perinatal or postnatal exposure during breastfeeding) or sexually (sexual exposure). Distinguishing and documenting the mode of HIV acquisition (MOHA) is crucial to further research on the different needs and outcomes for ALHIV and to tailor HIV services to their needs. Age-based cut-offs have been used to attribute MOHA but have not been validated.

Objective: We are failing to reach 95-95-95 for adolescents living with HIV (ALHIV). Sexual abuse and intimate partner violence (IPV) may impact antiretroviral therapy (ART) adherence, with high rates of 17.4 and 29.

Long-acting injectable anti-retroviral therapy (LAART) may overcome barriers to long-term adherence and improve the survival of adolescents and young people living with HIV (AYLHIV). Research on the acceptability of LAART for this age-group is limited. We asked 953 AYLHIV about their preferred (theoretical) ART mode of delivery (pill, injectable, or other) in 2017-2018, before LAART was available or known to AYLHIV in South Africa.

Background: The intergenerational effects of HIV require long-term investigation. We compared developmental outcomes of different generations impacted by HIV-children of mothers not living with HIV, the 'second generation' (ie, with recently infected mothers) and the 'third generation' (ie, children of perinatally infected mothers).

Methods: A cross-sectional community sample of N=1015 young mothers (12-25 years) and their first children (2-68 months, 48.

Background: Adolescents living with HIV exhibit lower levels of adherence to antiretroviral therapy (ART) than other age groups. Poverty is a key barrier to ART adherence. This study aims at understanding how alleviating poverty through structural and internal pathways can help increase ART adherence among adolescents.

Adolescents are a crucial generation, with the potential to bring future social and economic success for themselves and their countries. More than 90% of adolescents living with HIV reside in sub-Saharan Africa, where their mental health is set against a background of poverty, familial stress, service gaps, and an HIV epidemic that is now intertwined with the COVID-19 pandemic. In this Series paper, we review systematic reviews, randomised trials, and cohort studies of adolescents living with and affected by HIV.

Introduction: The World Health Organization recommends full disclosure of HIV-positive status to adolescents who acquired HIV perinatally (APHIV) by age 12. However, even among adolescents (aged 10-19) already on antiretroviral therapy (ART), disclosure rates are low. Caregivers often report the child being too young and fear of disclosure worsening adolescents' mental health as reasons for non-disclosure.

Objectives: This paper reports HIV prevalence, incidence, progress towards the UNAIDS (90-90-90) targets, and HIV drug resistance among adolescents living with HIV in South Africa. We conducted secondary analyses using data extracted from the South African national HIV prevalence surveys (2005-2017). Analyses were stratified by sex and age (10-14 and 15-19-years), presenting weighted descriptive statistics, and realised totals.

Introduction: Antiretroviral treatment (ART) adherence rates are lower among adolescents living with HIV (ALHIV) than among adults and children, but more evidence is needed on long-term sustained ART adherence among ALHIV. This study assesses rates of sustained ART adherence in a cohort of adolescents in South Africa.

Methods: A prospective cohort of adolescents (10-19 years) living with HIV (baseline sample N = 1 046, 55% female, mean age 13.

The mental health of adolescents (10-19 years) remains an overlooked global health issue, particularly within the context of syndemic conditions such as HIV and pregnancy. Rates of pregnancy and HIV among adolescents within South Africa are some of the highest in the world. Experiencing pregnancy and living with HIV during adolescence have both been found to be associated with poor mental health within separate explorations.

Objective: Preventing secondary HIV transmission from adolescents and young people living with HIV (AYPLHIV) to their partners and children is critical to interrupting the HIV infection cycle in sub-Saharan Africa. We investigated predictors of secondary HIV transmission risk (past-year sexual risk combined with past-year viremia) among AYPLHIV in South Africa.

Design: A prospective cohort of AYLPHIV in South Africa recruited n = 1046 participants in 2014-2015, 93.

Objective: Adolescent antiretroviral treatment (ART) adherence remains critically low. We lack research testing protective factors across both clinic and care environments.

Background: Identifying risk and protective factors for adolescent antiretroviral therapy (ART) adherence is a public health priority, given high HIV-related mortality in this population. An area that merits further investigation is the relationship between bullying victimization, mental health problems, and ART nonadherence among adolescents living with HIV (ALHIV). However, no known studies assess effects of bullying on adolescent nonadherence or risk and protective factors that could moderate this relationship.

Introduction: There is a growing interest in adolescent motherhood and HIV among policymakers and programme implementers. To better shape services and health outcomes, we need evidence on reproductive aspirations and contraception use in this high-risk group, including the effect of motherhood and HIV status. We report data from a large survey of adolescent girls and young women conducted in a mixed rural-urban district in South Africa.
