Including the voice of children <15-years-old in paediatric global health research.

Purpose Of Review: Despite evidence of the benefits of including children's voices in global health research, they continue to be underrepresented. Implementation of how to include children's voices appears to remain an obstacle to their inclusion in global health research. In this manuscript, we present an epistemological frame that advocates children as experts of their own experiences and knowledge-bearers.

The impact of an innovative community-based peer-led intervention on uptake and coverage of sexual and reproductive health services among adolescents and young people 15-24 years old: results from the Yathu Yathu cluster randomised trial.

Background: The Yathu Yathu ("For Us, By Us") cluster-randomized trial (CRT) evaluated a peer-led community-based sexual and reproductive health(SRH) intervention implemented to address persistent barriers to SRH service use among adolescents and young people (AYP). We report the impact of the intervention on coverage of key SRH services among AYP.

Methods: The trial was conducted from Jul 2019-Oct 2021 in two urban communities in Lusaka, Zambia, divided into 20 zones (~ 2350 AYP/zone).

Understanding the language barriers to translating informed consent documents for maternal health trials in Zambia: a qualitative study.

Objective: Providing comprehensible information is essential to the process of valid informed consent. Recruitment materials designed by sponsoring institutions in English-speaking, high-income countries are commonly translated for use in global health studies in other countries; however, key concepts are often missed, misunderstood or 'lost in translation'. The aim of this study was to explore the language barriers to informed consent, focusing on the challenges of translating recruitment materials for maternal health studies into Zambian languages.

Lessons learned from implementation of four HIV self-testing (HIVST) distribution models in Zambia: applying the Consolidated Framework for Implementation Research to understand impact of contextual factors on implementation.

Background: Although Zambia has integrated HIV-self-testing (HIVST) into its Human Immunodeficiency Virus (HIV) regulatory frameworks, few best practices to optimize the use of HIV self-testing to increase testing coverage have been documented. We conducted a prospective case study to understand contextual factors guiding implementation of four HIVST distribution models to inform scale-up in Zambia.

Methods: We used the qualitative case study method to explore user and provider experiences with four HIVST distribution models (two secondary distribution models in Antenatal Care (ANC) and Antiretroviral Therapy (ART) clinics, community-led, and workplace) to understand factors influencing HIVST distribution.

Self-reported uptake of STI testing services among adolescents and young people aged 15-24 years: Findings from the Yathu Yathu cluster randomized trial in Lusaka, Zambia.

There is little evidence regarding community-based delivery of STI testing and treatment for youth aged 15-24 (AYP) in Zambia. In a cluster-randomised trial, we evaluated whether offering syndromic STI screening through community-based, peer-led sexual and reproductive health services (Yathu Yathu) with referral to a local health facility for testing, increased self-reported testing for STIs (other than HIV) among AYP. Two communities in Lusaka were divided into 10 zones each (20 zones in total); by community, zones were randomly allocated (1:1) to Yathu Yathu or control.

Evaluation of COVID-19 antigen rapid diagnostic tests for self-testing in Lesotho and Zambia.

Introduction: The use of antigen rapid tests (Ag-RDTs) for self-testing is an important element of the COVID-19 control strategy and has been widely supported. However, scale-up of self-testing for COVID-19 in sub-Saharan Africa is still insufficient and there is limited evidence on the acceptability of self-testing and agreement between Ag-RDT self-testing and Ag-RDT testing by professional users. A joint collaboration (Botnar Research Centre for Child Health-European & Developing countries Clinical Trials Partnership)was established between Lesotho and Zambia to address these gaps in relation to Ag-RDT self-testing and contribute to increasing its use in the region.

Demographics of sources of HIV-1 transmission in Zambia: a molecular epidemiology analysis in the HPTN 071 PopART study.

Background: In the last decade, universally available antiretroviral therapy (ART) has led to greatly improved health and survival of people living with HIV in sub-Saharan Africa, but new infections continue to appear. The design of effective prevention strategies requires the demographic characterisation of individuals acting as sources of infection, which is the aim of this study.

Methods: Between 2014 and 2018, the HPTN 071 PopART study was conducted to quantify the public health benefits of ART.

Factors associated with use of community-based, peer-led sexual and reproductive health services by adolescent boys and young men aged 18-24 in Lusaka, Zambia: A case control study nested in the Yathu Yathu trial.

Introduction: Adolescents and young people (AYP) aged 15-24 years have the least access to facility-based sexual and reproductive health (SRH) services, including HIV services. The Yathu-Yathu cluster-randomized trial (CRT) in Zambia tested whether a novel peer-led community-based approach increased knowledge of HIV status amongst AYP. In this nested case-control study, we aimed to identify factors associated with non-attendance to the Yathu Yathu hubs by adolescent boys and young men (ABYM) aged 18-24-years.

Facilitators and barriers to COVID-19 testing in community and clinical settings: Lessons learned from Lesotho and Zambia.

The sudden emergence of the coronavirus disease 2019 (COVID-19) had a devastating impact on health systems and population health globally. To combat the spread of COVID-19, countries enacted guidelines and safety measures, including testing, contact tracing, and quarantine. It was unclear the extent to which uptake of COVID-19 testing and other health initiatives would be accepted in countries with a history of dealing with widespread communicable disease transmission such as HIV or Tuberculosis.

Predictors of participant retention in a community-based HIV prevention cohort: perspectives from the HPTN 071 (PopART) study.

Introduction: In 2021, there were 38.4 million people living with HIV (PLHIV) globally, of which 20.6 million (54%) were living in Eastern and Southern Africa.

Does distribution of menstrual products through community-based, peer-led sexual and reproductive health services increase use of appropriate menstrual products? Findings from the Yathu Yathu trial.

Background: Globally, millions of adolescent girls and young women (AGYW) who menstruate have limited access to appropriate and comfortable products to manage their menstruation. Yathu Yathu was a cluster randomised trial (CRT) that estimated the impact of community-based, peer-led sexual and reproductive health (SRH) services on knowledge of HIV status among adolescents and young people aged 15-24 (AYP). Among the services offered through Yathu Yathu were free disposable pads and menstrual cups.

A Narrative Synthesis of Literature on the Barriers to Timely Diagnosis and Treatment of Cancer in Sub-Saharan Africa.

Poor cancer survival outcomes in sub-Saharan Africa (SSA) have been linked to delays in diagnosis and treatment. Here we present a detailed overview of the qualitative literature evaluating the barriers to receiving timely diagnosis and treatment of cancer in SSA. The PubMed, EMBASE, CINAHL, PsycINFO databases were searched to identify qualitative studies reporting on barriers to timely diagnosis of cancer in SSA published between 1995 and 2020.

The impact of community-based, peer-led sexual and reproductive health services on knowledge of HIV status among adolescents and young people aged 15 to 24 in Lusaka, Zambia: The Yathu Yathu cluster-randomised trial.

Background: The growing population of adolescents and young people (AYP) aged 15 to 24 in sub-Saharan Africa face a high burden of HIV in many settings. Unintended pregnancies among adolescent girls in the region remain high. Nonetheless, the sexual and reproductive health (SRH) service needs of AYP have remained underserved.

Delays in seeking, reaching and access to quality cancer care in sub-Saharan Africa: a systematic review.

Objectives: Late presentation and delays in diagnosis and treatment consistently translate into poor outcomes in sub-Saharan Africa (SSA). The aim of this study was to collate and appraise the factors influencing diagnostic and treatment delays of adult solid tumours in SSA.

Design: Systematic review with assessment of bias using Risk of Bias in Non-randomised Studies of Exposures (ROBINS-E) tool.

Uptake of medical male circumcision with household-based testing, and the association of traditional male circumcision and HIV infection.

Objectives: Voluntary medical male circumcision (VMMC) is an important component of combination HIV prevention. Inclusion of traditionally circumcised HIV negative men in VMMC uptake campaigns may be important if traditional male circumcision is less protective against HIV acquisition than VMMC.

Methods: We used data from the HIV Prevention Trials Network (HPTN) 071 (PopART) study.

Disseminating complex primary outcome results from a community-randomised trial to Zambian communities: lessons learned using a community dialogue approach in the HPTN 071 (PopART) trial.

The HPTN 071 (PopART) trial of universal HIV testing and treatment to reduce HIV incidence was conducted in nine communities in South Africa and 12 in Zambia. The trial's primary outcome results were complicated to explain. Dissemination of these complicated results in participating communities in Zambia was done using a community dialogue approach.

Assessing knowledge, acceptability and social implications of a peer-to-peer HIV self-testing kit distribution model among adolescents aged 15-24 in Zambia and Uganda-HISTAZU: a mixed-method study protocol.

Introduction: HIV self-testing (HIVST) across sub-Saharan African countries may be acceptable as it overcomes significant barriers to clinic-based HIV testing services such as privacy and confidentiality. There are a number of suggested HIVST distribution models. However, they may not be responsive to the testing service needs of adolescents and young people (AYP).

"You have a self-testing method that preserves privacy so how come you cannot give us treatment that does too?" Exploring the reasoning among young people about linkage to prevention, care and treatment after HIV self-testing in Southern Malawi.

Background: Young people, aged 16-24, in southern Malawi have high uptake of HIV self-testing (HIVST) but low rates of linking to services following HIVST, especially in comparison, to older generations. The study aim is to explore the barriers and facilitators to linkage for HIV prevention and care following uptake of HIV self-testing among young Malawians.

Methods: We used qualitative methods.

Adapting community-based sexual and reproductive health services for adolescents and young people aged 15-24 years in response to COVID-19 in Lusaka, Zambia: the implications on the uptake of HIV testing services.

Background: Across Sub-Saharan Africa, adolescents and young people (AYP) aged 15-24 have limited access to sexual and reproductive health (SRH) services, including HIV testing services (HTS). In response, the Yathu Yathu study was implemented in two high-density communities in Lusaka, Zambia. Yathu Yathu provides comprehensive, community-based, peer-led SRH services, including differentiated HTS (finger-prick and HIV self-testing) and comprehensive sexuality education (CSE).

Access to menstrual hygiene products through incentivised, community-based, peer-led sexual and reproductive health services before and during the COVID-19 pandemic: findings from the Yathu Yathu trial.

Background: Access to affordable and effective menstrual hygiene products (MHP) is critical to the menstrual health of adolescent girls and young women (AGYW). In this mixed-methods analysis, we use data from a programme delivering comprehensive sexual and reproductive health (SRH) services to describe access to MHP and how COVID-19-related closures affected access to MHP; we use qualitative data to understand AGYW's experience accessing products during the study.

Methods: Between September 2019-January 2021, we used data routinely collected from ten Yathu Yathu hubs offering community-based, peer-led SRH services to adolescents and young people aged 15-24.

Closing the gap: did delivery approaches complementary to home-based testing reach men with HIV testing services during and after the HPTN 071 (PopART) trial in Zambia?

Introduction: The HPTN 071 (PopART) trial demonstrated that universal HIV testing-and-treatment reduced community-level HIV incidence. Door-to-door delivery of HIV testing services (HTS) was one of the main components of the intervention. From an early stage, men were less likely to know their HIV status than women, primarily because they were not home during service delivery.

Adolescent Health Series: Engagement with young people as partners in health research: Four case studies from Sub-Saharan Africa.

Objectives: Existing health services for young people (YP)(10-24 years), which are predominantly designed for but not with young people, often do not meet YP's needs. The 2018 Global Consensus Statement on meaningful adolescent and youth engagement affirms that YP have a fundamental right to actively and meaningfully engage in all matters that affect their lives. We present four case studies from three countries in sub-Saharan Africa as practical examples of the engagement of young people as partners in health research.

Insaka: mobile phone support groups for adolescent pregnant women living with HIV.

Background: Mobile phone-based interventions have been demonstrated in different settings to overcome barriers to accessing critical psychosocial support. In this study, we aimed to assess the acceptability and feasibility of a phone-based, peer-to-peer support group intervention for adolescent pregnant women aged 15-24 years living with HIV in Zambia.

Methods: Sixty-one consenting participants were recruited from Antenatal Clinics of two large urban communities in Lusaka.
