  • Interventions Supporting Disclosure Among Children and Adolescents Living with HIV

    Open AccessChristina Laurenzi, Cassandra Carels et al.ARTICLEAIDS and Behavior2026

    HIV status disclosure remains a persistent challenge for children and adolescents aged 6-19 years. Disclosure is critical to improving treatment adherence, viral suppression, and psychosocial wellbeing, and promoting informed decision-making. This scoping review aimed to identify evidence on interventions focused on disclosing children's and adolescents' HIV statuses to them, and those supporting them with onward disclosure. We conducted a global…

  • Cost-effectiveness of Zvandiri, a community-based support intervention to reduce virological failure in adolescents living with HIV in Zimbabwe

    Open AccessCollin Mangenah, Webster Mavhu et al.ARTICLEPLOS Global Public Health2025

    Improving antiretroviral therapy (ART) adherence among adolescents living with HIV (ALHIV) improves outcomes, but with resource implications. We conducted a cost-effectiveness analysis extrapolating the costs and benefits of a community-based peer-support intervention (Zvandiri) among ALHIV in Zimbabwe. We used a de-novo multistate Markov decision-analytic model that simulated Zvandiri lifetime costs and benefits on viral suppression, death rates…

  • “Now that I took TPT, it’s affecting my ART adherence, viral load, even my wellbeing in the community”. Exploring acceptability and experience of Tuberculosis Preventive Treatment among adolescents li…

    Open AccessJoni Lariat, Rufaro Mbundure et al.ARTICLEPLOS Global Public Health2025

    Tuberculosis preventive treatment (TPT) is increasingly offered to people living with HIV in high-burden settings, including adolescents and young people (AYPLHIV). Evidence demonstrates that AYPLHIVs’ HIV treatment engagement is improved by the provision of tailored support. How to effectively adapt this support to accommodate multimorbidity care, such as TPT alongside ART, warrants attention to deliver sustained optimal outcomes. We conducted q…

  • Mental health and other clinical and social characteristics of young mothers living with HIV in Zimbabwe

    Open AccessZ Mupambireyi, Victoria Simms et al.ARTICLEAIDS Care2025

    Young women living with HIV (YWLHIV) experience numerous stressors including treatment management and poor parent modelling. We investigated YWLHIV’s mental health and other clinical and social characteristics to inform tailored support. YWLHIV (15–24 years old) participating in a peer-support model tailored for young mothers (Young Mentor Mum intervention) completed a self-administered interview and had clinical and psychological assessments in …

  • Reported impact of creativity in the Wakakosha (‘You’re Worth It’) internal stigma intervention for young people living with HIV in Harare, Zimbabwe

    Open AccessLauren Heniff, Nadine Ferris France et al.ARTICLEPLOS Global Public Health2024

    Internal stigma (negative judgements towards oneself) continues to be a barrier to HIV treatment, management and care, and has global public health consequences. People living with HIV (PLHIV) who report internal stigma are less likely to seek care, adhere to treatment and can experience increased depression and lower quality of life. The Wakakosha (‘You’re Worth It’) programme sought to reduce internal stigma among young PLHIV using inquiry-base…

  • Leaving no one behind? Addressing inequitable HIV outcomes by attending to diversity

    Open AccessJoni Lariat, Webster Mavhu et al.ARTICLEPLOS Global Public Health2024

    Leaving nobody behind in the fight to end the HIV epidemic as a public health threat depends on addressing inequities in optimal HIV outcomes. Consistently overlooked in research, policy and programming are young lesbian, gay, bisexual, transgender, queer/questioning and intersex (LGBTQI+) people who are living with HIV. This study engaged young LGBTQI+ people in Zimbabwe to better understand their experiences of living with HIV and the support t…

  • A conceptualization and psychometric evaluation of positive psychological outcome measures used in adolescents and young adults living with HIV

    Open AccessJermaine M Dambi, Frances M Cowan et al.ARTICLEPLOS Global Public Health2024

    Introduction Sub-Saharan Africa bears the greatest burden of HIV, with comorbid mental conditions highly prevalent in people living with HIV. It is important to evaluate the mental health of adolescents and young adults living with HIV (AYALHIV) comprehensively by measuring both negative and positive psychological constructs. There has been a proliferation of interest in positive psychological outcome measures, but the evidence of their psychomet…

  • Wakakosha “You are Worth it”

    Open AccessNadine Ferris France, Elaine Byrne et al.ARTICLEFrontiers in Public Health2023

    Introduction Self-stigma—negative self-judgements or core beliefs—can result in feelings of shame, worthlessness and self-blame, and impacts social interaction, mental health and health service utilization among people living with HIV (PLHIV). Few interventions target self-stigma among PLHIV and, to our knowledge, none until now for adolescents and young people LHIV (AYPLHIV) in sub-Saharan Africa. We present qualitative findings on the perceived…

  • Intersecting Epidemics

    Open AccessTalent Tapera, Clifford O Odimegwu et al.ARTICLEAIDS and Behavior2023

    Globally, there have been considerable achievements towards HIV care and treatment. AIDS-related deaths have been reduced by 60% since the peak in 2004. Potentially, the fight against the HIV epidemic was made more difficult with the outbreak of COVID-19. Thus, this study examined the implications of COVID-19 in the utilization of HIV care and treatment services among people living with HIV on antiretroviral therapy (ART) in Zimbabwe. The study a…

  • Principles for delivery of youth lay counsellor programs

    Open AccessMerrian J Brooks, Nicola Willis et al.ARTICLEJournal of Global Health2022

    There is accumulating evidence that lay counsellors can effectively provide structured, evidence-based counselling interventions to improve mental health outcomes [1–4]. Lay counsellors help alleviate overburdened health systems that have limited numbers of mental health professionals through ‘task-shifting,’ a process of referring straightforward, or common mental health illness to lay workers who have received counselling training [...]

  • Assessing Engagement of Adolescents and Young Adults (AYA) in HIV Research

    Open AccessKadija M Tahlil, Laura Rachal et al.ARTICLEAIDS and Behavior2022

    Engagement of adolescents and young adults (AYA) in HIV research is increasing in many settings. We organized a crowdsourcing open call to solicit examples of how AYA have been engaged in HIV research in Africa and to develop an engagement typology. We formed a steering committee, promoted the open call, organized judging and recognized finalists. We used a multi-methods approach to identify emerging themes and measure engagement. We received 95 …

  • My story”—HIV positive adolescents tell their story through film

    Open AccessNicola Willis, L Frewin et al.ARTICLEChildren and Youth Services Review2014Cited by: 5References: 8

    The global commitment to universal access for people in need of antiretroviral therapy has transformed the lives of adolescents with HIV. In contrast, there has been limited commitment at policy or service level to the need for effective therapeutic interventions which can help them to cope with their life experiences. It is imperative that the scale up of antiretroviral therapy programmes is accompanied by evidence-based therapeutic approaches i…
