An Episodic Analysis of Substance Use and Risky Sexual Behavior in a Racially Diverse Sample of Young Men Who Have Sex with Men

Abstract

Many studies have examined the relations between drug use and sexual behaviors; however, few have utilized episodic data to examine the co-occurrence of both behaviors within the same episode. This study surveyed 403 racially and ethnically diverse gay, bisexual, and other young men who have sex with men (YMSM; ages 18–29) in New York City. Men were surveyed about their sexual behavior and concurrent use of illicit substances and alcohol during their most recent sexual encounter with their main and/or casual partner(s). Logistic regression models were built to analyze predictors of unprotected oral and anal intercourse with main and casual partners. Results suggest that use of inhalant nitrates and alcohol increased the odds of men engaging in unprotected receptive anal intercourse (URAI) and men who identified as middle or high socioeconomic status (SES) were at lower odds of engaging in URAI with their main partner. Use of other illicit substances was not associated with unprotected sexual intercourse. These findings indicate a need to further consider the role of licit substances used by YMSM as a means of further reducing the incidence of HIV infection in this population. In addition, the high rates of unprotected anal intercourse among men reporting a main partner has the potential to be a significant source of HIV risk, and should be further explored among YMSM.
