Accurate measurement of antiretroviral therapy (ART) adherence remains challenging and there are few data assessing the validity of self-reported adherence among perinatally HIV-infected adolescents. We examined adolescent and caregiver reports of adolescent adherence among perinatally-infected adolescents aged 9-14 years in Cape Town, South Africa, and explored factors that may modify associations between reported adherence and elevated viral load (VL). Among 474 adolescents (median age 12.0 years; median duration of ART use 7.5 years), elevated VL and caregiver- and adolescent-report of missed ART doses were common. Elevated VL was particularly prevalent among older, male adolescents. Low-moderate concordance was observed between caregiver and adolescent report. Among adolescents aged ≥ 12 years, caregiver- and adolescent-reported adherence was associated with elevated VL across most items assessed, but few significant associations were observed among adolescents &lt; 12 years of age. Refined adherence measures and tools to identify adolescents who require adherence interventions are needed in this context.
