Optimizing adolescent HIV care
Adolescents living with HIV (ALHIV) in Zambia experience poorer treatment outcomes than adults, with lower viral suppression and higher loss to follow-up rates. Electronic medical record (EMR) systems such as SmartCare aim to strengthen patient monitoring, but their utility is contingent on high data quality. Accurate monitoring of ALHIV treatment outcomes is critical for improving patient care and supporting progress toward UNAIDS 95–95-95 targe…
Pilot testing of a digitally enabled, peer supported self-management intervention for adolescents and youth living with HIV in the Western Cape, South Africa
Adolescents and youth living with HIV (AYLHIV) face increased health risks and need targeted support to optimally engage in treatment. The Supporting Adolescents to be Resilient and Thrive (S-SMART) programme is a digitally enabled, peer-supported self-management intervention designed to enhance psychosocial and treatment engagement outcomes among AYLHIV. This pilot study evaluated the feasibility and acceptability of S-SMART among AYLHIV aged 15…
HIV Viral Re-Suppression on Second-Line ART in Southern Zimbabwe
The national prevalence of HIV among adults in Zimbabwe was 10.4% in 2023, while the HIV prevalence in Bulawayo Metropolitan Province was 11.7%. The country achieved the UNAIDS Fast Track goals of 95-95-95 ahead of the 2030 target, by reporting an ART coverage of 97.0% and a viral suppression rate of 95.0%. As the number of people on ART continues to grow, it is expected that the number of patients failing current first-line non-nucleoside treatm…
Determinants of viral suppression among young people living with HIV and on antiretroviral therapy in Eswatini
Background : HIV treatment, adherence, and retention in care are fundamental in achieving viral load suppression (VLS) and fighting the HIV pandemic. The Government of Eswatini has decentralised antiretroviral treatment (ART) services and introduced differentiated HIV service delivery models to improve treatment outcomes for all people living with HIV, including young people. It is imperative to investigate the success of these initiatives in imp…
Experiences of support by unsuppressed adolescents living with HIV and their caregivers in Windhoek, Namibia
Background: Adolescents living with HIV (ALHIV) lag behind younger children and adults in the achievement of HIV care and treatment targets for HIV epidemic control. Treatment outcomes for adolescents may be influenced by their experiences with the support provided in HIV programs. We report on the experiences of virally unsuppressed adolescents and their caregivers with the current support in primary healthcare settings in Namibia. Methods: = 11…
Responsive public health doctoral education
Institutional capacity for doctoral training is key to addressing the complex challenges facing the global south. In the context of the need for skilled knowledge workers in health systems and growing demand for doctoral places, we reflect on the evolution of a public health doctoral programme in a South African School of Public Health. Through this case, we aim to contribute to wider debates on the form and content of emerging public health doct…
Illustrations of Coping and Mental Well-Being of Adolescents Living with HIV in Cape Town, South Africa During Covid
Adolescents living with HIV (ALHIV) are the fastest-growing population living with HIV globally. The COVID-19 pandemic disrupted health systems, thereby negatively affecting the quality and availability of HIV care and support services. This study describes the challenges and treatment experiences of ALHIV on ART at a public primary healthcare facility in a low-socioeconomic community in Cape Town, South Africa during the COVID-19 pandemic. A qua…
Patterns and Predictors of HIV Comorbidity among Adolescents and Young Adults in South Africa
Adolescents and young adults (AYA) are identified as a high-risk group for HIV acquisition. However, health services are generally not sensitive to the needs of this priority population. In addition, multimorbidity (having more than one disease in an individual) is not well studied among AYA, as it is typically associated with older individuals. This paper reports on commonly co-occurring disease conditions and disease patterns in AYA, aged 15-24…
Multimorbidity patterns in South Africa
Introduction: South Africa has the largest burden of HIV worldwide and has a growing burden of non-communicable diseases; the combination of which may lead to diseases clustering in ways that are not seen in other regions. This study sought to identify common disease classes and sociodemographic and lifestyle factors associated with each disease class. Methods: Data were analyzed from the South African Demographic and Health Survey 2016. A latent…
Two-year retention in care for adolescents on antiretroviral therapy in Ehlanzeni district, South Africa
Adolescents living with HIV (ALHIV) struggle to remain engaged in HIV-related care and adhere to antiretroviral treatment (ART) due to a myriad of physical, psychological and cognitive-developmental challenges. We report on the profile of ALHIV aged 10-19 years on ART and the clinical factors associated with their retention in care. A retrospective cohort analysis was conducted with 16,108 ALHIV, aged 10-19 years, who were enrolled in 136 ART cli…
Asking the Experts
There has been an increased focus on the mental health of adolescents living with HIV (ALHIV), because evidence shows that poor mental health outcomes are associated with lower rates of adherence and retention in HIV care. However, the research to date has predominantly focused on addressing mental health problems and reducing symptoms of mental illness rather than strengthening mental wellness [positive mental health]. Consequently, little is kn…
Determinants and rates of retention in HIV care among adolescents receiving antiretroviral therapy in Windhoek, Namibia
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)
Multimorbidity Patterns in a National HIV Survey of South African Youth and Adults
As the South African population continues to age, the prevalence of multimorbidity is likely to increase which will further impact the health care system. The prevalence of multimorbidity in the population was relatively low but reached up to 20% in the oldest age groups. The largest disease cluster was the combination of diabetes and hypertension; followed by HIV and hypertension. The gains in improving adherence to antiretrovirals amongst treat…
Psychosocial Support Programme Improves Adherence and Health Systems Experiences for Adolescents on Antiretroviral Therapy in Mpumalanga Province, South Africa
(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…
Aging with HIV
With improved access to antiretroviral treatment (ART), adults with HIV live longer to reach older age. The number of older adults living with HIV is increasing steadily, giving rise to a new population of interest in HIV research and for invigorated considerations in health service delivery and policy. We analysed the profile of comorbidities in older people (50 years and older) living with HIV in South Africa. We conducted a secondary analysis …
Closing the HIV Treatment Gap for Adolescents in Windhoek, Namibia
Windhoek joined the Fast-Track Cities Initiative in 2017 to optimize HIV service delivery for adolescents, promoting adherence and sustaining viral suppression. Recent surveys and programmatic data show that the treatment gap remains greatest among children and adolescents living with HIV. A retrospective cohort analysis of adolescents living with HIV (ALHIV) receiving antiretroviral therapy (ART) at Windhoek healthcare facilities was conducted. …
Comparing Patients' Experiences in Three Differentiated Service Delivery Models for HIV Treatment in South Africa
Differentiated service delivery for HIV treatment seeks to enhance medication adherence while respecting the preferences of people living with HIV. Nevertheless, patients' experiences of using these differentiated service delivery models or approaches have not been qualitatively compared. Underpinned by the tenets of descriptive phenomenology, we explored and compared the experiences of patients in three differentiated service delivery models usi…
Life in a child-headed household
The overwhelming rate of HIV-related mortality in the past decades has eroded traditional safety nets for orphans, of which the extended family is the most critical. This has led to the formation of new household structures, i.e. child- and youth-headed households, as children and youths are left to live alone and look after themselves. These types of households are a growing phenomenon in many African countries and are increasingly being recogni…
These Women are Making a Statement Against Rape and yet the only Thing Y'All can Focus on is ‘Eww They're Naked’”
Sexual assault on campuses has been identified as a pervasive public health problem. In April 2016, students across South African universities launched the #Endrapeculture campaign to express their frustration against university policies which served to perpetuate a rape culture. The use of hashtag activism during the protest served to spark online public debates and mobilize support for the protests. This article describes the public reactions t…
Qualitative Methods Without Borders
Applying Qualitative Methods to Investigate Social Actions for Justice Using Social Media
Social media is becoming a valuable resource for hosting activism as illustrated in the rise of the hashtag movements, such as #MeToo and #Endrapeculture, used to speak out against rape culture. In this article, we discuss the use of social media as the source and object of research, using the case of the 2016 South African #nakedprotest. We used naturalistic observation on Facebook comment threads and followed these up with online Facebook focus…
Leveraging the Photovoice Methodology for Critical Realist Theorizing
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 polic…
Using the realist interview approach to maintain theoretical awareness in realist studies
Realist evaluation submits that theories and models of how, why, for whom and under what circumstances programs work could be formulated by conceptualizing the relational links between the context within which programs are implemented, the generative mechanisms the programs trigger, and the outcomes of interest. Qualitative and quantitative data collection and analysis allow for the description of the relevant context, the generative mechanisms, …
Patients Are Not Following the [Adherence] Club Rules Anymore
There is growing evidence that differentiated care models employed to manage treatment-experienced patients on antiretroviral therapy could improve adherence to medication and retention in care. We conducted a realist evaluation to determine how, why, for whom, and under what health system context the adherence club intervention works (or not) in real-life implementation. In the first phase, we developed an initial program theory of the adherence…
On the Road to HIV/Aids Competence in the Household
When aiming to provide chronic disease care within the context of human resource shortages, we should not only consider the responsibility of the individual person living with HIV/AIDS (PLWHA) but also the capacity of the social environment to actively encourage a lifestyle that fosters health. In this social environment, extensive efforts are thus required to increase HIV/AIDS knowledge, reduce stigma, stimulate HIV testing, improve health care-…

Correlates of Suicide Risk Among Secondary School Students in Cape Town
The aim of this study was to assess correlates of suicide risk in a South African school-based population ( N = 1,157) from three secondary schools in Cape Town. Results indicated that using the Suicide Risk Screen (SRS; Eggert, Herting, & Thompson, 1995) a high rate of learners screened in at possible suicide risk (31.6%). Anger control problems, low self-esteem, perceived stress and unmet school goals were identified as predictors for suicide r…
Lay health workers in primary and community health care for maternal and child health and the management of infectious diseases
BACKGROUND: Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. Little is known, however, about the effectiveness of LHW interventions. OBJECTIVES: To assess the effects of LHW interventions in primary and community health care on maternal and child health and the management of infectious diseases. SEARCH STRATEGY: For the current version of this review we searched The Cochrane Central Register of Control…
Of Remedies and Poisons
During an ethnographic study of barriers to, and compliance with, antiretroviral (ARv) treat- ment in the South Africa’s West Coast region, our team came across a general sense amongst heath careproviders that there was a lively illicit trade in antiretroviral medications. in itself, this is seen to be a barrier to adherence for many of their patients whose medication is traded to, or stolen by, drug dealers. independent anecdotal evidence is eme…
