Objective
To measure rates of ART use and virologic suppression among perinatally infected (PIY) and behaviorally infected youth (BIY) linked to care in the United States, and examine the effects of demographic, biomedical, and psychosocial factors on those rates.
Methods
Between 2009–2012, 649 PIY and 1,547 BIY in 20 Adolescent Medicine Trials Network for HIV/AIDS Interventions sites completed cross-sectional surveys via audio computer- assisted self-interviews. Viral load data were collected from chart abstraction or blood draw.
Results
Overall 82.4% of PIY and 49.1% of BIY reported current ART use. Only 37.0% of PIY and 27.1% of BIY were virologically suppressed. Virologic suppression rates did not vary as a function of time since HIV diagnosis in either group. Consistent HIV care and no current substance abuse were significant correlates of ART use among PIY. These variables and non-African American race were some factors associated with virologic suppression for PIY (ORs Ps < .05). Among BIY, older age, heterosexuals, employment, and education were significantly related to ART use (ORs Ps < .05); suppression was related to ART use >6 months, >90% ART adherence, and consistent HIV care (ORs Ps < .05). Nearly 75% (n = 498) of non-suppressed youth reported unprotected sex in the past 3 months.
Conclusions
There are continued challenges with successfully treating youth even once diagnosed and linked to HIV care. Strategies targeting barriers to ART access, use and virologic suppression are needed to optimize the impact of the "Treatment as Prevention" paradigm among PIY and BIY.
