Association Between Age of Anal Sex Debut and Adult Health Behaviors Among Sexual Minoritized Men Living with HIV.

Earlier age of anal sex debut (ASD) has been linked with contemporary and long-term health outcomes, including vulnerability to HIV acquisition. The goal of this study was to utilize a life course approach to examine associations between earlier ASD and recent health behaviors among sexual minoritized men (SMM) living with HIV. A total of 1156 U.S. SMM living with HIV recruited from social and sexual networking apps and websites completed online surveys as part of a longitudinal eHealth intervention. Data from baseline surveys were analyzed to determine associations between age of ASD and adult health outcomes, including mental health, HIV viral load, and substance use. The median age of ASD among these participants was 17 years old, consistent with other work. Earlier ASD was significantly associated with a greater likelihood of past 2-week anxiety (AOR = 1.45, 95% CI 1.07-1.97) and past 3-month opioid use (AOR = 1.60, 95% CI 1.13-2.26); no significant associations were found for recent depression, HIV viral load, or stimulant use. Earlier ASD may function as an important proxy measure for deleterious health outcomes in adulthood, particularly recent anxiety and opioid use. Expansion of comprehensive and affirming sexual health education is critical to early engagement of individuals with a higher risk of HIV acquisition, with plausible downstream health benefits lasting into adulthood among SMM living with HIV.
