IntroductionCrowdsourcing, a participatory approach to solicit ideas from a large group of diverse individuals, provides an opportunity to nurture youth participation in HIV self-testing service design. The objective of this study was to describe the responses to a crowdsourcing contest aimed at soliciting ideas on how to promote HIV self-testing (HIVST) among young people in Nigeria. MethodsThe "4 Youth by Youth" HIV Self-Testing Crowdsourcing contest was an online and off-line contest that asked Nigerian youth (10-24 years old) for ideas in response to the following: How might we promote HIVST among young people in Nigeria? All data were collected and analyzed between October 2018, and June 2019. Ideas and perceptions generated from the crowdsourcing contest were qualitatively analyzed using thematic content analysis. Specifically, four reviewers analyzed whether the ideas generated were desirable (appealing to young people), feasible (easy to implement) and impactful (will significantly influence HIVST uptake among young people). ResultsA total of 903 entries were received in response to the contest prompt. Participants submitted entries in various forms: online form (39.7%), offline Dropbox (44.6%), email (6.1%) and

Background Youth are at high risk for HIV, but are often left out of designing interventions, including those focused on adolescents. We organized a designathon for Nigerian youth to develop HIV self-testing (HIVST) strategies for potential implementation in their local communities. A designathon is a problem-focused event where participants work together over a short period to create and present solutions to a judging panel. Methods We organized a 72-h designathon for youth (14–24 years old) in Nigeria to design strategies to increase youth HIVST uptake. Proposals included details about HIVST kit service delivery, method of distribution, promotional strategy, and youth audience. Teams pitched their proposals to a diverse seven-member judging panel who scored proposals based on desirability, feasibility, potential impact and teamwork. We examined participants’ socio-demographic characteristics and summarized themes from their HIVST proposals. Results Forty-two youth on 13 teams participated in the designathon. The median team size was 3 participants (IQR: 2–4). The median age was 22.5 years (IQR: 21–24), 66.7% were male, 47.4% completed tertiary education, and 50% lived in Lagos State. Themes from proposals included HIVST integration with other health services, digital marketing and distribution approaches, and engaging students. Judges identified seven teams with exceptional HIVST proposals and five teams were supported for further training. Conclusions The designathon provided a structured method for incorporating youth ideas into HIV service delivery. This approach could differentiate HIV services to be more youth-friendly in Nigeria and other settings.

Background Young people in low- and middle-income countries are often neglected in designing youth-friendly health services, especially HIV testing and preventive services. Designathons, which are time-bounded co-creation events where individuals gather in teams to develop solutions to a problem, could promote youth participation and ownership of health services. Objective The purpose of this study is to examine youth participation in a designathon to create youth-friendly health services in Nigeria. Methods Our designathon was based on crowdsourcing principles and informed by a human-centered design approach. The designathon included an open call for Nigerian youths between 14 and 24 years to share ideas on how to promote uptake of HIV self-testing services and a three-day sprint event that brought together diverse teams to develop strategies enhancing linkage to care. Teams pitched their solutions to a panel of five independent experts who scored ideas based on the desirability, feasibility, potential impact, and teamwork. We used descriptive statistics to summarize participants’ demographics and conducted a content analysis to synthesize themes from youth proposals. Results Nine hundred seventy-six youth across Nigeria applied to join the designathon. Forty-eight youth in 13 teams participated in the designathon with a median age of 20 years (IQR: 17–22]. Boys and young men were 48.5% (446/919) of the total applicants, 62.5% (30/48) of the designathon participants, and 63.6% (7/11) of the finalists. Students, from all educational levels, represented 91.2% (841/922) of the total applicants, 88.4% (38/43) of the designathon participants, and 90.0% (9/10) of the finalists. About twenty-three percent (3/13) of the final proposals were top ranked. The three finalist approaches to optimize youth-friendly health services centered on decentralizing service delivery to young people through mobile health technologies, use of mobile tents, or peer support services. Conclusions Our open call engaged diverse groups of Nigerian youth, including young women and students. Our data suggest that designathons may be useful for developing tailored youth-friendly health services. Further research is needed to understand the designathon process and the effectiveness of the finalist submissions.

Introduction Youth engagement in HIV research is generally recognized as essential, but often neglected or minimally implemented in practice. Engagement is a process of working collaboratively with diverse groups of people to address common issues. We conducted a scoping review of youth HIV prevention interventions in sub‐Saharan Africa to identify and categorize forms and levels of youth engagement across the lifespan of intervention research. Methods We followed Arksey and O'Malley's framework for organizing a scoping review. We searched seven databases for related articles on identified intervention studies through May 28 th 2020. Included studies focused on youth (10 to 24 years old) HIV prevention interventions in sub‐Saharan Africa. Two reviewers independently examined citations and full manuscripts for inclusion. Data were extracted on study characteristics, location, description of youth engagement and extent of engagement. Youth engagement approaches were categorized based on Hart’s ladder as substantial engagement (strong youth decision‐making power), moderate engagement (shared decision making with adults), minimal engagement (no youth decision‐making power) or no engagement. Results We identified 3149 citations and included 112 studies reporting on 74 unique HIV interventions. Twenty‐two interventions were in low‐income countries, 49 in middle‐income countries, and three were in both. Overall, only nine interventions (12%) had substantial or moderate youth engagement, two‐thirds (48, 65%) had minimal youth engagement and 17 interventions (23%) had no youth engagement. We also identified specific engagement strategies (e.g. youth‐led research, crowdsourcing) that were feasible in multiple settings and resulted in substantial engagement. Conclusions We found limited youth engagement in youth HIV prevention intervention studies in sub‐Saharan Africa. However, several activities resulted in substantial youth engagement and could be relevant in many low‐and‐middle‐income‐country (LMIC) settings.

Background Advances and proliferation of technologies such as mobile phones may provide opportunities to improve access to HIV/STI services and reach young people with high risk for HIV and STI. However, the reach, uptake, and sustainability of mobile health (mHealth) HIV/STI interventions targeting young people aged 10–24 years in low- and middle-income countries (LMICs) are largely unknown. To address this gap and to inform implementation science research, a review was conducted to summarize what is known, and what we need to know about implementing mhealth interventions for HIV/STI prevention targeting young people in LMICs. Methods We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for this review. Drawing upon Proctor’s eight implementation outcome measures, we evaluated the acceptability, adoption, appropriateness, cost, feasibility, fidelity, penetration, and sustainability of  m-health HIV/STI interventions targeting young people in LMICs. The search was performed from September 2020–January 2021 and updated on March 1, 2021, in Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, SCOPUS, Global Health, and Web of Science. Eligible studies were required to include an HIV/STI prevention outcome, target young people aged 10–24 years, include a comparison/control group, and reporting of atleast one implementation outcome as outlined by Proctor. Results A total of 1386 articles were located, and their titles and abstracts were screened. Of these, 57 full-text articles were reviewed and subsequently, and 11 articles representing 6 unique interventions were included in the systematic review. Acceptability 6 (100%), appropriateness 6 (100%), and feasibility 5(83%) were the most frequently evaluated implementation outcomes. Adoption 2 (33%), fidelity 1 (17%), and cost 1 (17%) were rarely reported; penetration and sustainability were not reported. Conclusions This review contributes to implementation science literature by synthesizing key implementation outcomes of mHealth HIV/STI interventions targeting young people in LMICs. Future research is needed on m-health HIV/STI implementation outcomes, particularly the penetration, cost, and long-term sustainability of these interventions. Doing so will enhance the field’s understanding of the mechanisms by which these interventions lead or do not lead to changes in high HIV/STI risk and vulnerability among young people in LMICs.
