For the study in the journal AIDS and Behavior, researchers surveyed 202 young sexual minority men and transgender women—two high-priority populations for HIV prevention—to better understand why some were more likely than others to take PrEP. According to the Centers for Disease Control and Prevention, sexual minority men are the community most affected by HIV, making up 69% of all new diagnoses in 2018, and transgender populations are disproportionately affected by HIV and prevention challenges. While Black and Hispanic/Latinx populations are mostly likely to be newly diagnosed with HIV, PrEP users are more likely to be white. The researchers, who are part of the Rutgers School of Public Health’s Center for Health, Identity, Behavior, and Prevention Studies (CHIBPS), found that while 98% of the study’s participants were aware of PrEP, less than 25% were currently taking it.
