The HIV Biobehavioral Data Repository stores de-identified demographic, behavioral, psychosocial, structural, medical chart abstraction, biological data, and frozen specimens in more than 300 adults living with HIV over 6 waves of data collection. To help advance science, we have recently added approximately 100 well-matched HIV uninfected adults to the Data Repository.
New participants are added regularly and we welcome collaborations with new investigators to answer important HIV-related research questions.
|Data Elements Contained in the HIV Biobehavioral Data Repository|
HIV-specific biomarkers (CD4+ T cell count, HIV-Viral RNA);
