This NOFO supports research on HIV/STD risk and prevention behavior in an era when new pre-exposure prophylaxis (PrEP) methods are becoming available for a diverse community-based sample of gay, bisexual, and other men who have sex with men (MSM). The aim is to study PrEP use and other HIV/STD prevention behaviors over time among MSM in three regions of the US, one of which should include the US South. The study should also serve to develop and test (quantitatively and qualitatively) brief PrEP and other HIV/STD prevention messaging to enhance protective behaviors among MSM.
