What is the ATN?
The Adolescent Medicine Trials Network for HIV Interventions (ATN) conducts innovative and collaborative research that explores promising strategies to support sexual health among adolescents and young adults ages 13 through 24.
The ATN is the only research network in the United States devoted solely to HIV prevention and care for youth, bringing together adolescents, communities, and researchers to enrich the health and well-being of youth and young adults.

The IMPACT Study Is Open for Enrollment!
We are thrilled to announce that the IMPACT study has opened for enrollment!
Stimulant drug use (e.g., crystal methamphetamine, cocaine, ecstasy, MDMA) is a substantial public health problem among young people. Using stimulants makes it more likely that young people will engage in behaviors that increase the likelihood of acquiring HIV.
In response, the IMPACT study combines HIV sexual health counseling with evidence-based cognitive behavioral therapy to treat depression that focuses on helping participants re-engage in activities that generate feelings of enjoyment and reduces HIV acquisition and transmission likelihood in young people who use stimulants in the context of sex.
If successful, this intervention will be ready for use in a variety of settings, like substance use treatment centers or community health organizations.
Three New ATN Scholars Selected
The ATN Scholars Program provides under-represented scientists who are within 10 years of completing a terminal degree, postdoc, or first medical residency with the skills, knowledge, and network to excel as independent investigators in adolescent HIV prevention.
Three new scholars joining the ATN are:
April Bell, PhD, MPH
University of California, San Francisco
Kevon-Mark Phillip Jackman, DrPH, MPH
Johns Hopkins University
Juan Pablo Zapata, PhD
Northwestern University
ATN Youth Poster Featured at ISRII Scientific Meeting
A poster created about and by the ATN’s youth Subject Matter Research Consultants (SMRC) was presented at the International Society for Research on Internet Interventions (ISRII) 13th Scientific Meeting from August 4-7, 2025.
The poster presentation outlined the program’s innovative framework and analyzed data about youth satisfaction, academic/professional benefit, and impact on interest in careers in health and research.
