AbstractIntroductionAchieving sustained HIV viral suppression is a key strategy to optimize the health and wellbeing of those living with HIV. Sub‐optimal adherence to antiretroviral therapy (ART) in adolescents and young people living with HIV (AYPLHIV) in Southern Africa, due to a range of social and contextual factors, including poor mental health, has presented a substantial challenge to meeting targets aimed towards improving treatment outcomes and reducing transmission. With the increasing availability of viral load (VL) testing in Southern Africa, there is an opportunity to better understand the relationship between VL literacy, wellbeing and adherence among adolescents.MethodsWe conducted qualitative interviews with 45 AYPLHIV aged 10–24 years in three districts (urban, peri‐urban and rural) in Zimbabwe between March and August 2021. The sample was purposively selected to represent a range of experiences related to HIV status disclosure, gender, marital status and treatment experience. Separate workshops were conducted with 18 healthcare workers (HCWs) and 20 caregivers to better understand existing support mechanisms to AYPLHIV accessing ART. We used thematic analysis to examine adolescent VL literacy, treatment support networks, experiences of clinic interactions, VL testing procedures and barriers to adherence.ResultsVL literacy was consistently under‐developed among participants. Comprehension of phrases commonly heard during clinic visits, such as TND (target not detected) and "high" and "low" VL, were better understood by older participants. VL testing was predominantly understood as a clinical procedure that enables HCWs to monitor treatment adherence. Absent throughout the interviews were descriptions of how viral suppression improves health and quality of life, likely fosters wellbeing and enhances self‐esteem, enables participation in education and social activities, and eliminates the risk of onward transmission.ConclusionsIt is imperative that we reconsider how routine VL monitoring is communicated to and understood by AYPLHIV. Reframing ART, including VL test results, in terms of the psychosocial benefits that viral suppression can generate is likely to be crucial to motivating AYPLHIV to maintain optimal treatment engagement and develop self‐management approaches as they move into adulthood. Access to accurate information tailored to individual concerns and circumstances can support AYPLHIV to achieve wellbeing.

AbstractIntroductionLow rates of viral suppression among adolescents living with HIV (ALHIV) indicate that more effective support is urgently required at scale. The provision of peer support has generated considerable enthusiasm because it has the potential to ameliorate the complex social and relational challenges which underpin suboptimal adherence. Little is known about the impact on young peer supporters themselves, which is the focus of this paper.MethodsWe present qualitative findings from the Zvandiri trial investigating the impact of a peer support intervention on the viral load for beneficiaries (ALHIV, aged 13 to 19 years) in Zimbabwe. The Zvandiri peer supporters aged 18 to 24 years, known as community adolescent treatment supporters (CATS), are themselves living with HIV. Individual in‐depth interviews were conducted in late 2018 with 17 CATS exploring their experiences of delivering peer support and their own support needs. Interviews were analysed iteratively using thematic analysis.ResultsThe CATS reported that being peer supporters improved their own adherence behaviour and contributed to an improved sense of self‐worth. The social connections between the CATS were a source of comfort and enabled them to develop skills to manage the challenging aspects of their work. Two substantial challenges were identified. First, their work may reveal their HIV status. Second, managing the emotional labour of this caring work; given how commonly the complexity of the beneficiaries' needs mirrored the circumstances of their own difficult lives. Both challenges were ameliorated by the support the CATS provided to each other and ongoing supervision from the adult mentor. There was variation in whether they felt their roles were appropriately valued through the remuneration they received and within the health system. There was a consensus that their experience meant that they would graduate from being a CATS with transferable skills that could enhance their employability.ConclusionsTheir experiences illustrate the advantages and opportunities of being a CATS. To minimize potential harms, it is vital to ensure that they feel valued in their role, which can be demonstrated by the provision of appropriate remuneration, recognition and respect, and that there is continued investment in ongoing support through ongoing training and mentoring.

AbstractIntroductionAdolescents are at increased risk of HIV virological non‐suppression compared to adults and younger children. Common mental disorders such as anxiety and depression are a barrier to adherence and virological suppression. The aim of this study was to identify factors associated with virological non‐suppression among adolescents living with HIV (ALWH) in Zimbabwe who had symptoms of common mental disorders.MethodsWe utilized baseline data from a cluster‐randomized controlled trial of a problem‐solving therapy intervention to improve mental health and HIV viral suppression of ALWH. Sixty clinics within 10 districts were randomized 1:1 to either the intervention or control arm, with the aim to recruit 14 adolescents aged 10 to 19 per clinic. Adolescents were eligible if they scored ≥7 on the Shona Symptom Questionnaire measuring symptoms of common mental disorders. Multivariable mixed‐effects logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for factors associated with non‐suppression, defined as viral load ≥1000 copies/mL.ResultsBetween 2 January and 21 March 2019 the trial enrolled 842 participants aged 10 to 19 years (55.5% female, 58.8% aged <16). Most participants (N = 613) were taking an NNRTI‐based ART regimen (13 PI‐based, 216 unknown) and median duration on ART was six years (IQR three to nine years, 240 unknown). Of the 833 with viral load data 292 (35.1%) were non‐suppressed. Virological non‐suppression was independently associated with male sex (adjusted OR (aOR) = 1.43, 95% CI 1.04 to 1.97), and with not knowing one's own HIV status (aOR = 1.77, 95% CI 1.08 to 2.88), or knowing one's status but not disclosing it to anyone (aOR = 1.99, 95% CI 1.36 to 2.93), compared to adolescents who knew their status and had disclosed it to someone.ConclusionsALWH with symptoms of common mental disorders have high prevalence of virological non‐suppression in Zimbabwe, especially if they do not know their status or have not disclosed it. In general adolescents should be informed of their HIV status, with encouragement on the beneficial health and social effects of viral suppression, to incentivise adherence. Efforts to strengthen the operationalization of disclosure guidelines for adolescents should now be prioritized.

AbstractIntroductionAdolescents and young people comprise a growing proportion of new HIV infections globally, yet current approaches do not effectively engage this group, and adolescent HIV‐related outcomes are the poorest among all age groups. Providing psychosocial interventions incorporating psychological, social, and/or behavioural approaches offer a potential pathway to improve engagement in care and health and behavioural outcomes among adolescents and young people living with HIV (AYPLHIV).MethodsA systematic search of all peer‐reviewed papers published between January 2000 and July 2020 was conducted through four electronic databases (Cochrane Library, PsycINFO, PubMed and Scopus). We included randomized controlled trials evaluating psychosocial interventions aimed at improving engagement in care and health and behavioural outcomes of AYPLHIV aged 10 to 24 years.Results and discussionThirty relevant studies were identified. Studies took place in the United States (n = 18, 60%), sub‐Saharan Africa (Nigeria, South Africa, Uganda, Zambia, Zimbabwe) and Southeast Asia (Thailand). Outcomes of interest included adherence to antiretroviral therapy (ART), ART knowledge, viral load data, sexual risk behaviours, sexual risk knowledge, retention in care and linkage to care. Overall, psychosocial interventions for AYPLHIV showed important, small‐to‐moderate effects on adherence to ART (SMD = 0.3907, 95% CI: 0.1059 to 0.6754, 21 studies, n = 2647) and viral load (SMD = −0.2607, 95% CI −04518 to −0.0696, 12 studies, n = 1566). The psychosocial interventions reviewed did not demonstrate significant impacts on retention in care (n = 8), sexual risk behaviours and knowledge (n = 13), viral suppression (n = 4), undetectable viral load (n = 5) or linkage to care (n = 1) among AYPLHIV. No studies measured transition to adult services. Effective interventions employed various approaches, including digital and lay health worker delivery, which hold promise for scaling interventions in the context of COVID‐19.ConclusionsThis review highlights the potential of psychosocial interventions in improving health outcomes in AYPLHIV. However, more research needs to be conducted on interventions that can effectively reduce sexual risk behaviours of AYPLHIV, as well as those that can strengthen engagement in care. Further investment is needed to ensure that these interventions are cost‐effective, sustainable and resilient in the face of resource constraints and global challenges such as the COVID‐19 pandemic.

The global HIV response is leaving children and adolescents behind. Because of a paucity of studies on treatment and care models for these age groups, there are gaps in our understanding of how best to implement services to improve their health outcomes. Without this evidence, policymakers are left to extrapolate from adult studies, which may not be appropriate, and can lead to inefficiencies in service delivery, hampered uptake, and ineffective mechanisms to support optimal outcomes. Implementation science research seeks to investigate how interventions known to be efficacious in study settings are, or are not, routinely implemented within real-world programmes. Effective implementation science research must be a collaborative effort between government, funding agencies, investigators, and implementers, each playing a key role. Successful implementation science research in children and adolescents requires clearer policies about age of consent for services and research that conform to ethical standards but allow for rational modifications. Implementation research in these age groups also necessitates age-appropriate consultation and engagement of children, adolescents, and their caregivers. Finally, resource, systems, technology, and training must be prioritized to improve the availability and quality of age-/sex-disaggregated data. Implementation science has a clear role to play in facilitating understanding of how the multiple complex barriers to HIV services for children and adolescents prevent effective interventions from reaching more children and adolescents living with HIV, and is well positioned to redress gaps in the HIV response for these age groups. This is truer now more than ever, with urgent and ambitious 2020 global targets on the horizon and insufficient progress in these age groups to date.
