DeVost MA, et al. - Researchers seek to determine a difference in sexually transmitted infection (STI) incidence between men who have sex with men (MSM) who met their last sexual partner through a geosocial networking (GSN) app and MSM who met their last partner via other venues. They identified no relationship between STI incidence and whether one's last sexual partner was met via GSN app. However, there appeared an association between STI incidence and having used GSN apps to meet sexual partners in the past 3 months. The number of venues used to meet partners and testing positive for any STI were noted to have a dose-response relationship.
