RESUMEN
Introduction: sub-Saharan Africa is experiencing a boom in the number of adolescents and young adults living with HIV (AYALHIV). Existing HIV intervention programs are mainly for children and adults living with HIV, with little attention paid to AYALHIV. Characterizing this population is necessary for planning, and designing, AYALHIV-centered HIV intervention programs. Methods: a retrospective single-center, hospital-based chart review was conducted at the largest HIV clinic in Ghana. We examined routinely collected data for AYALHIV (aged 10-24 years) on antiretroviral therapy (ART) for at least 1 year and in active care from 1st January to 31st December 2019. Data was collected using a structured data extraction form. The Chi-square and the Student´s t-test were used to compare characteristics between adolescents and young adults. Results: of 252 AYALHIV, 68% (172/252) were adolescents with a median age of 17 years (IQR 13-19); 32% were young adults with a median age of 22 years (IQR: 20-24). Most (56.7% (143/252)) AYALHIV were female. Almost 40% were orphans. Eighty-six percent of AYALHIV had HIV type I infection. The commonest mode of HIV acquisition among adolescents was vertical transmission (70.5%) and that among young adults was via unprotected sex (31.3%). 88% of AYALHIV were on non-nucleoside reverse transcriptase inhibitors-based regimen. The viral suppression rate among AYALHIV was 78%. Conclusion: the study shows there is a growing population of AYALHIV most of which are adolescents. About two-fifths were orphans. Policymakers and HIV programs should ensure AYALHIV-centred interventions are developed for this vulnerable population.
