Abstract
Background
Methamphetamine use is associated with disproportionate risk of HIV infection and increased risk of depression among sexual minority men. The purpose of the study was to estimate the association between clinical depression diagnoses and sexual risk-taking among cisgender men who have sex with men (MSM) who use methamphetamine.
Method
From March 2014 through January 2016, 286 MSM who use methamphetamine but were not seeking treatment for methamphetamine use disorder were enrolled to participate in a technology-based randomized controlled trial to reduce methamphetamine use and HIV sexual risk behaviors; participants were assessed for major depressive episodes (MDE) and persistent depressive disorder (PDD) at baseline. Multivariate clustered zero-inflated negative binomial regression analyses of condomless anal intercourse (n = 282; 1,248 visits) estimated the association between this baseline diagnostic result and engagement in sexual risk-taking over time.
Results
Participants predominantly identified as nonwhite (80%), averaged 42 years of age, and reported a HIV prevalence rate of 46%. Engagement in sexual risk-taking consistently demonstrated a positive curvilinear relationship with clinical depression severity, such that, for example, participants without clinical depression (59% of the sample; coef. = 1.16) and those with MDE (36% of the sample; coef. = 1.45) both demonstrated elevated rates of condomless anal sex with anonymous partners relative to participants with PDD (5% of the sample; analytical reference category; both coef. p < 0.05). Data also demonstrated a trend (p = 0.053) of reduced sexual risk-taking with main partners among participants diagnosed with MDE (coef. = −0.94).
Conclusions
Methamphetamine use among participants in this study inverted the functional form of the relationship between depression and sexual risk among MSM observed in prior studies. Whereas low-grade depression has been associated with increased sexual risk-taking in prior samples of MSM, methamphetamine upends this relationship, such that the greatest engagement in sexual risk-taking occurred among those diagnosed with MDE at baseline. Additional research is warranted to clarify how methamphetamine influences sexual risk-taking among MSM with/without comorbid depression.
