Reasons for methamphetamine use and type of drug-use administration and associations with sexual risk behavior by HIV-status among high-risk MSM in the United States
Lead Author: Gordon Mansergh
Findings: For both HIV positive and HIV negative men, taking methamphetamine (“meth”) to have “better sex” was a primary motivator (among ten possible motivators) associated with meth use. For both HIV positive and HIV negative men, meth use itself is consistently associated with sexual risk behavior, even when considering motivations for meth use. Programs to reduce meth-sex and sex risk should focus on (a) the issue (true or untrue) of meth use facilitating “better sex” and (b) addressing meth use directly, given its consistent association with sexual risk even when considering various meth-use motivations.
Relevance: This large study of HIV+ and HIV-, substance-using men who have sex with men (MSM) in Chicago, Los Angeles, New York City, and San Francisco (Project MIX) sought to better understand motivation and context for meth use during sex and its link to sexual risk behavior, in order to develop informed programs to reduce meth-sex risk among MSM.

Background: MSM continue to be disproportionately affected by HIV, and methamphetamine (meth) use is associated with MSM risk behavior. Better understanding of the associations of reasons for and type of meth use administration with HIV risk behavior is needed to develop more effective programs to reduce meth-linked sexual risk.
Methods: A convenience sample of substance-using MSM (N=600 HIV-negative and n=608 HIV-positive) was enrolled in a randomized intervention trial in Chicago, Los Angeles, New York City, and San Francisco (2005-08). Multivariate (stepwise) logistic regression analyses were stratified by HIV status and tested the association of nine reasons for most of the respondent's meth use in the prior 6 months (e.g., more sex, better sex); their most common type of meth use administration (snort, smoke, inject); whether they ever rectally inserted meth (“booty bump”); and the association of those variables with meth use and sexual risk behavior during their most recent anal sex encounter with a non-primary partner.
Results: For HIV-negatives, better sex (OR=2.3, 95% CI=1.3-4.4), injection meth use (OR=9.7, CI=2.5-38), and booty bumping (OR=4.1, CI=1.1-15) were associated with meth use during last sex. Not wanting to feel left out (OR=4.1, CI=1.7-10) and booty bumping (OR=3.5, CI=1.1-11) were associated with HIV-discordant unprotected anal sex. For HIV-positives, wanting to feel more connected (OR=4.1, CI=1.4-12) and to forget problems (OR=2.8, CI=1.4-5.6) were associated with meth use; not wanting to feel left out reduced the odds of meth use (OR=0.2, CI=0.1-0.5). Taking meth to feel better reduced the odds of reporting HIV-discordant unprotected insertive anal sex (OR=0.2, CI=0.1-0.8).
Conclusions: The differential reasons for using meth and meth use administration by HIV status can provide opportunities for targeted messages to reduce sexual risk. This includes addressing booty bumping and wanting better sex among HIV-negative MSM, and wanting to feel more connected and to avoid problems among HIV-positive MSM.
