Associations Between Major Depressive Episode, Methamphetamine Use Disorder Severity, and Engagement in Sexual Risk-Taking Among Methamphetamine-Using Men Who Have Sex with Men
Abstract
Depression and methamphetamine use have been associated with increased sexual risk-taking among men who have sex with men (MSM). This study estimated associations between current major depressive episode and/or methamphetamine use disorder and engagement in condomless anal intercourse (CAI). From March 2014 thru January 2016, 286 methamphetamine-using MSM were enrolled into a RCT to reduce methamphetamine use and sexual risk-taking. Analyses revealed that current major depressive episode was associated with a 92% increase in the rate of engagement in CAI with casual male partners (IRR 1.92; 95% CI 1.12–3.31) and a 76% increase in the rate of engagement in CAI with anonymous male partners (IRR 1.76; 95% CI 1.00–3.09). Additionally, for each unit increase in diagnostic methamphetamine use disorder severity, rates of engagement in CAI with anonymous male partners increased by 44% (IRR 1.44; 95% CI 1.11–1.87) and rates of engagement in CAI with exchange male partners increased by 140% (IRR 2.40; 95% CI 1.39–4.13). Neither diagnosis was associated with CAI with main male partners. Depression and methamphetamine use influence sexual risk-taking in unique ways, and interventions working with MSM should assess participants for both depression and methamphetamine use, and may tailor intervention content based on diagnostic outcomes.
