Pathways between adverse childhood experiences and viral suppression among male HIV-infected adolescents in South Africa.

Abstract

Fewer adolescents achieve viral suppression compared to adults. One impediment may be a history of adverse childhood experiences (ACEs). To better develop targets and timeframes for intervention, this study created more robust estimates of the impact of cumulative adversity on viral suppression, tested whether the association is sensitive to the timing of adversity, and simultaneously tested several potential mechanisms. We focus on males, who have lower viral suppression than females and who may contribute to disproportionate incidence among young women. We recruited 251 male perinatally HIV-infected adolescents aged 15-19 from HIV clinics in Soweto, South Africa. Adversity was captured using the Adverse Childhood Experience - International Questionnaire (ACE-IQ). Viral load was measured using blood samples; viral suppression was defined as <20 copies/mL. Indicators of medication adherence, depression, post-traumatic stress disorder (, and substance misuse were captured. A series of pathway analysis were performed. Our sample experienced a median of 7 lifetime and 4 past-year adversities. Less than half (44%) exhibited viral suppression. Adversity demonstrated a significant association with suppression; depression mediated the association. Primary prevention of adversity among children living with HIV is paramount, as is addressing the subsequent mental and behavioral health challenges that impede viral suppression among adolescents.
