In Nigeria, there is a paucity of data on knowledge and experiences of adolescents and young adults (AYAs) with HIV and ART, as well as their challenges maintaining optimal adherence. A mixed-method study was carried out between August and September 2018 among AYAs attending Lagos University Teaching Hospital, Nigeria. Data collection was via AYAs' hospital records, standardized questionnaires, and in-depth interviews (IDIs). The 4-day ACTG tool was used to measure adherence. Collected data were analyzed descriptively. Assessment of 34 AYAs comprising 18 (52.9%) males with 28 (82.4%) students revealed an overall knowledge score about ART and its effect of 73.6%. Twenty-five (73.5%) had poor knowledge of the development of resistant strains of HIV due to non-adherence recorded. Optimal adherence (≥95%) was recorded in 20 (58.8%) AYAs. IDI produced 4 themes: (i) reasons for non-adherence, (ii) ensuring optimal adherence, (iii) Social support systems and disclosure, and (iv) stigmatization. Our study provided formative data and revealed areas for intervention to improve knowledge and adherence to ART.
