    Mobile technologies represent potentially novel and scalable intervention delivery platforms for adolescents living with HIV (ALWH) in low- and middle-income countries. We conducted a prospective, mixed methods pilot study to evaluate the acceptability and feasibility of the WhatsApp® platform to deliver individual counseling services and facilitate peer support for ALWH in western Kenya. Thirty ALWH (17 female, mean age 15.4) on ART, engaged in HIV care and aware of their status, were enrolled. After 6 months, participants described their experiences with the intervention. Treatment adherence, stigma, and mental and behavioral health were assessed prospectively. Participants reported overall positive experiences and indicated that the platform encouraged peer network development. They endorsed potential benefits for treatment adherence, stigma reduction, and mental and behavioral health. All participants supported intervention expansion. In western Kenya, WhatsApp® was an acceptable and feasible platform for mobile counseling and peer support for ALWH.

    Gender differences in HIV knowledge among adolescents and young people in low-and middle-income countries: a systematic review
    (Frontiers Media, 2023-06-26) Chory, Ashley; Gillette, Emma; Callen, Grant; Wachira, Juddy; Sam-Agudu, Nadia A.; Bond, Keosha; Vreeman, Rachel; Graduate Medical Education, School of Medicine
    Objectives: This review seeks to critically analyze studies assessing gender differences in HIV-related knowledge among adolescents and young people in low- and middle-income countries. Methods: Using PRISMA guidelines and searching Pubmed and Scopus online databases, the search strategy combined search keywords with Boolean operators: (HIV OR AIDS) AND (knowledge) AND (gender) AND (adolescents). AC and EG conducted the search and independently reviewed all articles in Covidence software; conflicts were resolved by GC. Articles were included if they evaluated differences in HIV knowledge in at least two groups ages 10-24 and were implemented in a low or middle-income country. Results: The search resulted in 4,901 articles, of which fifteen studies, implemented in 15 countries, met selection criteria. Twelve evaluated differences in HIV knowledge in school settings; three evaluated participants in clinic settings. Adolescent males consistently scored higher in composite knowledge scores, as well as knowledge of HIV transmission, prevention, attitudes and sexual decision-making. Conclusion: We found gender-based discrepancies between knowledge, perception of risk and HIV prevalence among youth globally, with boys consistently scoring higher in HIV knowledge. However, there is significant evidence that social and cultural contexts render girls at high risk of HIV infection, and the gaps in girls' knowledge and boys' roles in HIV risk must be addressed urgently. Future research should consider interventions that facilitate discussion and HIV knowledge building across genders.

    A Qualitative Examination of Perceived Stigma and its Sources Among Adolescents Living With HIV in Western Kenya
    (Sage, 2022) Callen, Grant; Chory, Ashley; Sang, Festus; Munyoro, Dennis; Aluoch, Josephine; Scanlon, Michael; Enane, Leslie; McHenry, Megan; Wools-Kaloustian, Kara; Apondi, Edith; Vreeman, Rachel; Pediatrics, School of Medicine
    Introduction. Adolescents (10-19 years) living with HIV (ALWH) face unique challenges in controlling HIV long-term, including stigma and perception of stigma within their communities. Methods. We conducted a qualitative investigation of the sources of perceived HIV-related stigma with ALWH in western Kenya. Forty-six ALWH on ART, aware of their status, and engaged in care were enrolled. Interviews explored perceived stigma by probing the individuals and experiences that adolescents identify as causing or perpetuating their ongoing fears. Results. Participants (54% male, mean age 17.4) reported ongoing fears of stigmatization related to friends and peers not living with HIV. They described previous enacted and first-hand observations of stigma, most often occurring in pre-adolescence, by age mates or peers at school as the most common cause for their ongoing fears. Conclusions. Perceived stigma is prevalent among ALWH and develops from experiences in pre-adolescence. Anti-HIV stigma interventions addressing educators and children in school settings to combat perceived stigma at its source should be investigated.
