More than 2 million people are incarcerated in the United States with many millions more processed through correctional facilities annually. Communities impacted by incarceration are also disproportionately impacted by the HIV and sexually transmitted infection (STI) epidemics. However, relatively little is known about the behaviors that place individuals with a history of incarceration at risk for HIV/STI acquisition. We utilized clinical data from patients presenting to an STI clinic located in Providence, Rhode Island. A latent class analysis was conducted on reported HIV acquisition risk behavior and STI testing results on a total of 1129 encounters where a history of incarceration was reported. A total of three classes were identified. Class 1 (N = 187, 11%), more frequently reported 10+ sexual partners (45%), an STI diagnosis (48%) and sex while intoxicated (86%) in the past year as well as identifying as a man who has sex with other men (60%). Class 2 (N = 57, 5%) was more likely to report giving (53%) and receiving (44%) money/drugs for sex in the past year as well as a history of injecting drugs (61%) and using methamphetamine (60%). Class 3 (N = 885, 78%) most frequently reported 0-2 sexual partners (48%), identified as Black (27%), Hispanic/Latino (69%) and a man who only has sex with women (80%). Class 1 had significantly higher odds ratio (1.8, 95% confidence interval = 1.3-2.5) of testing HIV/STI positive. The results provide important insights into risk subgroups for those with a history of incarceration at risk of HIV/STI acquisition.
