Lower self-reported ART adherence among adolescents in boarding schools compared to day schools

Abstract

Introduction: Adolescents living with HIV (ALH) have poorer adherence to antiretroviral therapy (ART) than adults. Many ALH in sub-Saharan Africa (SSA) are enrolled in boarding schools where stigma is pervasive and may impact adherence.

Methods: We collected sociodemographic data, school information, medical history, and viral load (VL) data from ALH age 14-19 in 25 HIV clinics in 3 counties in Kenya. Using generalized estimating equations, we compared ART adherence in ALH attending day and boarding schools.

Results: Of 880 ALH, 798 (91%) were enrolled in school, of whom 189 (24%) were in boarding schools. Of those in school, median age was 16 (IQR: 15, 18), 55% were female, 78% had a parent as a primary caregiver, and 74% were on DTG-based ART. Median age at ART initiation was 6 years (IQR 3, 10).Overall, 227 (29%) ALH self-reported missing ART when school was in session (40% in boarding and 25% in day school). After adjusting for sociodemographic and HIV care characteristics, ALH in boarding schools were significantly more likely to self-report missing ART than those in day schools (adjusted Prevalence Ratio (aPR): 1.47, 95% CI 1.18, 1.83, p=0.001). Among 194 ALH, only 60% had undetectable (<20 copies/ml) HIV viral load (62% day schools and 51% boarding schools)(p=0.097).

Conclusion: ALH had high self-reported non-adherence overall, with worse adherence among those in boarding schools. Schools remain a critical untapped resource for improving ALH outcomes.
