IntroductionAdolescents living with HIV (ALHIV) on antiretroviral therapy (ART) globally report lower rates of viral suppression because of challenges to remain adherent and engage in HIV treatment. Psychosocial support is critical to meet the unique needs of ALHIV. Peer navigation has been found to be effective in supporting adults in ART adherence, but the evidence for adolescents is scant. Given the large proportion of adolescents on ART in sub-Saharan Africa, peers hold promise to deliver psychosocial support. The aim of this qualitative evidence synthesis is to review qualitative and mixed-methods studies describing experiences of peer navigation and support interventions for ALHIV on ART in sub-Saharan Africa.Methods and analysisThe population–concept–context configuration will be applied to identify suitable studies on ALHIV and on ART (population) and experiences of peer navigation and support (concept) and conducted in sub-Saharan African countries (context). The review will only include studies published in the English language. The following databases will be searched: PubMed, Wiley Library Online, EbscoHost (PsycArticles), MEDLINE, Scopus, CINAHL, WHO database and Google Scholar, for eligible qualitative studies published from January 2015 (to ensure relevance) to November 2025. Two-stage screening will be done by two reviewers independently. Extracted data will be thematically analysed with Atlas.Ti (v25) software. A narrative synthesis will be conducted to describe the reported outcomes, experiences and challenges with receiving and delivery of peer navigation and support interventions in sub-Saharan Africa. The review will adhere to Preferred Reporting Items for Systematic reviews and Meta-Analyses and Enhancing Transparency in Reporting the Synthesis of Qualitative Research reporting guidelines.Ethics and disseminationEthics approval is not required for this qualitative evidence synthesis. The findings will be submitted to a peer-reviewed journal and disseminated to via conference proceedings.PROSPERO registration numberCRD42024541951.

Factors Associated with Viral Suppression Among Adolescents on Antiretroviral Therapy in Homa Bay County, Kenya: A Retrospective Cross-Sectional Study
2021
Despite the success in initiating adolescents living with HIV on antiretroviral therapy (ART), questions remain about factors affecting viral suppression. In Kenya, only 63% of adolescents (aged 10-19 years) on ART had achieved viral suppression in 2016. We investigated factors associated with viral suppression among adolescents initiated on ART before November 30, 2017 in Homa Bay County, Kenya.
A retrospective cross-sectional analysis of 908 adolescents registered on ART for at least 6 months and with at least one documented viral load in the last 12 months, in six health facilities in Homa Bay County was conducted. Data were extracted from the electronic medical records and exported into an excel spreadsheet. Bivariate and multivariate logistic regression analyses were conducted to identify factors associated with viral suppression and adjust for confounding, using Stata 12.0.
Out of all participants, 80% (726) had achieved viral suppression (<1,000 copies of viral RNA/mL of blood at latest viral load count). After adjusting for other covariates, adolescents with good adherence to ART (AOR=2.3, 95% CI=1.38-3.84) and a most recent CD4 count of above 500 cells/mm
(AOR=1.87, 95% CI=1.13-3.08), were more likely to be virally suppressed. Adolescents on second line ART treatment (AOR=0.45, 95% CI=0.28-0.73) and having inadequate adherence to ART (AOR=0.26, 95% CI=0.11-63) were less likely to be virally suppressed.
Viral suppression for adolescents on ART in this study is significantly higher than the national prevalence in 2016 (80% vs 63%), but it is still below the WHO target of 90%. Enhanced adherence support for adolescents on ART should be implemented to improve long-term adherence. Specific interventions are needed to \"rescue\" adolescents on second-line ART regimens who may have a history of poor adherence.

(1) Background: Psychosocial support (PSS) plays a significant role in persistent adherence to and retention in antiretroviral therapy (ART) for adolescents living with the human immunodeficiency virus (ALHIV). This paper qualitatively explores the experiences of ALHIV on ART, who participated in a PSS programme in five public primary healthcare facilities in Mpumalanga Province in South Africa during the COVID-19 pandemic. (2) Methods: Data were collected through 24 focus group discussions with 173 ALHIV on ART and subjected to inductive thematic analysis. Informed consent was obtained before all data collection. (3) Results: The PSS programme facilitated the process of full HIV disclosure to these adolescents with the support of parents/guardians while motivating adherence through peer support groups and health education for improved treatment literacy. Participants reported positive health systems experiences, improved healthcare provider–client relations, and prompt access to health services. (4) Conclusions: The PSS programme successfully kept ALHIV engaged in ART care despite the health service disruptions encountered during the COVID-19 pandemic. We recommend rigorous evaluation of the effects of the PSS intervention on adherence to and retention in ART among ALHIV in HIV-endemic settings.

Determinants and rates of retention in HIV care among adolescents receiving antiretroviral therapy in Windhoek, Namibia: a baseline cohort analysis
2023
Background
Long-term engagement in HIV care is essential to achieving and maintaining viral suppression. Adolescents living with HIV (ALHIV) experience many barriers to remaining engaged in care and treatment programs. Higher attrition among adolescents compared to adults remains a huge concern due to unique psychosocial and health systems challenges adolescents face, and recently the COVID-19 pandemic effects. We report on determinants and rates of retention in care in adolescents aged 10–19 years enrolled on antiretroviral therapy (ART) in Windhoek, Namibia.
Methods
A retrospective cohort analysis of routine clinical data of 695 adolescents aged 10–19 years enrolled for ART at 13 Windhoek district public healthcare facilities, between January 2019 and December 2021 was conducted. Anonymized patient data were extracted from an electronic database and registers. Bivariate and Cox proportional hazards analysis were performed to determine factors associated with retention in care among ALHIV at 6, 12, 18, 24 and 36 months. Retention in care trends were also described using the Kaplan-Meier survival analysis.
Results
The retention in care rates at 6, 12, 18, 24 and 36 months were 97.7%, 94.1%, 92.4%, 90.2%, and 84.6%, respectively. Our study population had predominantly treatment-experienced adolescents, who initiated ART between birth and 9 years (73.5%), were on treatment for > 24 months (85.0%), and on first-line ART (93.1%). After controlling for confounders, the risk of dropping out of care was increased for older adolescents aged 15–19 years (aHR = 1.964, 95% CI 1.033–3.735); adolescents on switched ART regimens (Second line + Third line regimen) (aHR = 4.024, 95% CI 2.021–8.012); adolescents who initiated ART at 15–19 years (aHR = 2.179, 95%CI 1.100-4.316); and male adolescents receiving ART at a PHC clinic (aHR = 4.322, 1.332–14.024). Conversely, the risk of ALHIV dropping out of care decreased for adolescents whose TB screen results were negative (aHR = 0.215, 95% CI 0.095–0.489).
Conclusion
Retention in care rates among ALHIV in Windhoek do not meet the UNAIDS revised target of 95%. Gender-specific interventions are needed to keep male and older adolescents motivated and engaged in long-term care, and to promote adherence amongst those adolescents who were initiated on ART in late adolescence (15–19 years).

Patterns of Transition of Adolescents in an HIV Care Programme in Peri-Urban Cape Town, South Africa: A Photovoice Study
2025
Successful transition from paediatric to adult HIV care programme is a critical developmental milestone in the care trajectory of adolescents living with HIV (ALHIV). The transition process involves a shift from a structured, caregiver-supported healthcare model to one that requires independence and self-management. This process should be guided and supportive to ensure continued engagement in care and optimal adherence when ALHIV are transferred. This study utilised photovoice methods to explore the transition experiences of ALHIV in the Cape Town Metropole. Audio-recorded focus group data were transcribed verbatim and subjected to reflexive thematic analysis. Three distinctive patterns of behaviour from ALHIV were identified as themes. Type 1: socially reliant, dependent adolescent who heavily relies on family and peer support and struggles with adherence. Type 2: socially disconnected, hyper-independent adolescent, who is self-reliant, seeks solitude, and is generally resistant to external support. We configured a third (ideal) type, who is interdependent and able to self-manage their chronic condition, but within a supportive health care environment that provides positive healthcare and transition experiences. The findings underscore the need for supportive transition models promoting self-management skills, while facilitating a symbiotic relation with healthcare staff promoting sustained engagement in care well into adulthood. We recommend that adolescent or youth friendly services for ALHIV be expanded to support and monitor the transition process and outcomes in the adult HIV program.

Photovoice is a visual research methodology that integrates images and words to encourage the exploration of the experiences, perceptions, and meaning-making processes of individuals on various social phenomena. As a participatory qualitative methodology, Photovoice has been used within the interpretivist paradigm to explore various [public] health and social phenomena to enhance participants’ (co-investigators’) engagement and to lobby for policy. Despite its exponential growth and extensive application in the last two decades, its potential usefulness in critical realist-informed studies is unexplored. Herein, we highlight the epistemological and methodological alignment of the Photovoice methodology with the critical realist philosophy of science regarding the understanding of social phenomena through meaning-making. Drawing on the authors’ work on adolescents’ (non)adherence behavior on antiretroviral therapy, we illustrate the application of Photovoice methods in a critical realist-informed qualitative study. The emancipatory potential of the Photovoice methodology aligns with that of critical realist epistemology as they privilege participants’ (co-investigators’) knowledge generation and learning to better understand and take control of their situation - “integrated” knowledge translation. Methodologically, Photovoice provides a useful dialogue strategy for promoting discussions between the researcher and the co-investigators to obtain value-impregnated accounts to inform critical realist theorizing. The Photovoice methodology is appropriate for theorizing in critical realist research and especially suitable when engaging with suppressed or marginalized populations.

Adolescents living with HIV (ALHIV) face compounded health and psychosocial challenges while managing lifelong antiretroviral therapy (ART). Mental health difficulties among ALHIV are strongly associated with suboptimal adherence and disengagement from care. While mental illness is well documented, limited empirical evidence exists on the influence of positive mental wellness on adherence self-efficacy among ALHIV. This study assessed mental wellness among ALHIV and identified key psychosocial predictors of adherence self-efficacy in public healthcare facilities in Cape Town, South Africa.
A cross-sectional survey was conducted among ALHIV (
= 251) aged 10-19 years who were receiving ART at public healthcare facilities across the Cape Town metropole. Participants completed an electronic questionnaire that assessed ten mental wellness domains and adherence self-efficacy. Descriptive statistics were calculated to summarise participant characteristics and mental wellness scores, while Pearson correlations and multiple linear regression were done to identify associations and independent predictors of adherence self-efficacy using SPSS v29.
Most participants were aged 15-19 years (76.9%) and diagnosed with HIV at birth (68.9%). Mental wellness scores were high across all domains (
= 3.14-3.71). Hope (
= 3.71), spirituality (
= 3.58), and purpose in life (
= 3.52) were the highest-rated domains. All mental wellness domains were positively correlated with adherence self-efficacy (
< 0.001), with the strongest associations being purpose in life (
= 0.66), self-acceptance (
= 0.66) and resilience (
= 0.66). Hope (
< 0.001), resilience (
= 0.001), purpose in life (
= 0.03) and self-acceptance (
= 0.012) emerged as significant independent predictors.
Positive mental wellness and adolescent-centred psychosocial support in routine HIV care may strengthen adherence self-efficacy and support adolescents' confidence in managing treatment.

The antiretroviral adherence club intervention was rolled out in primary health care facilities in the Western Cape province of South Africa to relieve clinic congestion, and improve retention in care, and treatment adherence in the face of growing patient loads. We adopted the realist evaluation approach to evaluate what aspects of antiretroviral club intervention works, for what sections of the patient population, and under which community and health systems contexts, to inform guidelines for scaling up of the intervention. In this article, we report on a step towards the development of a programme theory-the assumptions of programme designers and health service managers with regard to how and why the adherence club intervention is expected to achieve its goals and perceptions on how it has done so (or not).
We adopted an exploratory qualitative research design. We conducted a document review of 12 documents on the design and implementation of the adherence club intervention, and key informant interviews with 12 purposively selected programme designers and managers. Thematic content analysis was used to identify themes attributed to the programme actors, context, mechanisms, and outcomes. Using the context-mechanism-outcome configurational tool, we provided an explanatory focus of how the adherence club intervention is roll-out and works guided by the realist perspective.
We classified the assumptions of the adherence club designers and managers into the rollout, implementation, and utilisation of the adherence club programme, constructed around the providers, management/operational staff, and patients, respectively. Two rival theories were identified at the patient-perspective level. We used these perspectives to develop an initial programme theory of the adherence club intervention, which will be tested in a later phase.
The perspectives of the programme designers and managers provided an important step towards developing an initial programme theory, which will guide our realist evaluation of the adherence club programme in South Africa.

Retention in care for adolescents who were newly initiated on antiretroviral therapy in the Cape Metropole in South Africa
2020
Background Long-term retention of adolescents aged 10 -19 years on antiretroviral therapy (ART) is crucial to achieve viral load suppression. However, it is reported globally that adolescents have lower retention in care (RiC) on ART, compared with children and adults. Objectives To determine the prevalence and predictors of RiC of adolescents over 2 years following initiation onto ART in public health facilities in the Metropole District Health Services of the Western Cape province in 2013. Methods Data of 220 adolescent patients who were newly initiated on ART in 2013 were extracted from the provincial electronic database, and subjected to univariate and bivariate analyses using SPSS. Results The rate of RiC post-initiation was low throughout the study period, that is, 68.6%, 50.5% and 36.4% at 4, 12 and 24 months, respectively. The corresponding post-initiation viral load suppression levels on ART of those remaining in care and who had viral loads monitored were 84.1%, 77.4% and 68.8% at 4, 12 and 24 months, respectively. Retention in care after initiation on ART was higher amongst younger adolescents (10-14 years), compared with older adolescents (15-19 years). Male adolescents were significantly more likely to be retained, compared with females. Pregnant adolescents were significantly less likely to be retained compared with those who were not pregnant. Conclusion Key interventions are needed to motivate adolescents to remain in care, and to adhere to their treatment regimen to achieve the target of 90% viral load suppression, with specific emphasis on older and pregnant adolescents.

COVID-19 - epidemiology
2025
Background: Adolescents living with HIV (ALHIV) in low socio-economic contexts face challenges related to physical development and health, stigma, and economic instability. The onset of the COVID-19 pandemic exacerbated these vulnerabilities, impacting the physical, mental, and social well-being of ALHIV. ALHIV were positioned in a particularly precarious situation, requiring them to navigate the disruptions caused by the pandemic while simultaneously striving to maintain resilience and adherence to their antiretroviral treatment (ART).
Objectives: To explore the resilience and vulnerability of ALHIV on ART in a peri-urban community in Cape Town, South Africa during the COVID-19 pandemic.
Methodology: A participatory photovoice study was employed with 20 ALHIV aged 14 to 19 years. Participants received basic training on photography techniques and were asked to capture images representing their experiences during the COVID-19 pandemic. These photographs were shared and discussed in both individual interviews and group discussions. All interviews and discussions were audio-recorded, and the resulting transcripts were analysed using content analysis to identify key themes and insights.
Results: Four key themes were identified: (1) disrupted routines and emotional strain, (2) support systems and coping mechanisms, (3) HIV treatment adherence facilitators and barriers, and (4) economic vulnerability and household stress. Despite the compounded challenges and significant hardships, ALHIV in this study demonstrated notable resilience, maintaining treatment adherence and a positive outlook despite economic struggles and social disruptions.
Conclusions: This study highlights the resilience and vulnerability of ALHIV in resource-limited settings. Findings underscore the need for targeted mental health and social support interventions to address their unique vulnerabilities. Strengthening healthcare access, social support networks, and local community resources can improve the well-being and coping capacity of ALHIV in future crises.
