To evaluate the ethics of involving adolescents in HIV research, we conducted a systematic review of the empiric literature.

Electronic databases Ovid Medline, Embase, and CINAHL were systematically searched using controlled vocabulary terms related to ethics, HIV, specified age groups, and empiric research studies. We reviewed titles and abstracts, including studies that collected qualitative or quantitative data, evaluated ethical issues in HIV research, and included adolescents. Studies were appraised for quality, data were extracted, and studies were analyzed using narrative synthesis.

We included 41 studies: 24 qualitative, 11 quantitative, 6 mixed methods; 22 from high-income countries (HIC), 18 from low- or middle-income countries (LMIC), and 1 from both HIC and LMIC. Adolescent, parent, and community perspectives assert the benefits of involving minors in HIV research. Participants in LMIC expressed mixed views regarding parental consent requirements and confidentiality, given adolescents’ both increasing autonomy and continued need for adult support. In studies in HIC, sexual or gender minority youth would not participate in research if parental consent were required or if there were confidentiality concerns. There was variation in the comprehension of research concepts, but adolescents generally demonstrated good comprehension of informed consent. Informed consent processes can be improved to increase comprehension and study accessibility. Vulnerable participants face complex social barriers that should be considered in study design.

Data support the inclusion of adolescents in HIV research. Empiric research can inform consent processes and procedural safeguards to ensure appropriate access.
