Abstract
BACKGROUND: Young Black gay, bisexual, and other men who have sex with men (YBMSM) are disproportionally affected by HIV. Seroadaptive strategies-modification of sexual behavior based on an individual's perceived serostatus, the perceived status of the partner, and/or HIV transmission risk by the type of sex act-are often used to reduce the risk of HIV transmission or acquisition. METHODS: We used demographic, behavioral, and clinical data from Ele[MEN]t, a prospective cohort study of YBMSM aged 18-29 years in Atlanta, GA, conducted during 2015-2019. The prevalence of seroadaptive strategies at baseline was reported, and latent class analysis was used to identify the latent classes of strategies for both YBMSM known and not known to be living with HIV. Latent classes were compared by key behavioral and clinical characteristics to validate our findings. RESULTS: In a 4-class model, the most common latent class of YBMSM not known to be living with HIV (32.4%) was characterized by all individuals reporting only having sex with men not perceived to be living with HIV. The most common latent class of YBMSM known to be living with HIV (48.2%) was characterized by a combination of serosorting strategies, including using condoms for anal sex with partners not known to be living with HIV and avoiding sex with men not known to be living with HIV. CONCLUSIONS: YBMSM use various patterns of strategies to reduce their HIV transmission or acquisition risk. Our study highlights the need for targeted HIV prevention recommendations based on individual behaviors.
