Pre-exposure Prophylaxis Awareness and Use Among Cisgender Men Who Have Sex With Men and Use Methamphetamine in 3 Western US Cities

Abstract

Background In the United States, cisgender men who have sex with men (MSM) who use methamphetamine are at substantial risk for HIV and can benefit from pre-exposure prophylaxis (PrEP). Methods We used data from the National HIV Behavioral Surveillance 2017 survey from Seattle, WA; Portland, OR; and Denver, CO, to estimate PrEP awareness and use in the past 12 months among MSM who use methamphetamine. We then compared these estimates with participants who do not use methamphetamine but meet other criteria for PrEP use (i.e., condomless anal sex or a bacterial sexually transmitted infection). We explored reasons for not using PrEP and challenges using PrEP. Results Of the 1602 MSM who participated in the 2017 National HIV Behavioral Surveillance survey in Seattle, WA; Portland, OR; and Denver, CO, 881 met the inclusion criteria for this study, of whom 88 (10%) reported methamphetamine use in the past 12 months. Most (95%) participants had heard of PrEP, and 35% had used it in the past 12 months. Pre-exposure prophylaxis awareness was lower among MSM who used methamphetamine (P = 0.01), but use was not different (P = 0.26). Among those who had not used PrEP, the most common reason for not using it was not thinking one's HIV risk was high enough (51%). Men who have sex with men who used methamphetamine were more likely to report that they were not sure PrEP would prevent them from getting HIV (38% vs. 19%, P = 0.002). Conclusions These results highlight the need for continued efforts to educate and promote PrEP uptake among MSM, particularly those who use methamphetamine.

Evolution of Risk Behaviors, Sexually Transmitted Infections and PrEP Care Continuum in a Hospital-Based PrEP Program in Barcelona, Spain: A Descriptive Study of the First 2 Years’ Experience

“…In our cohort, methamphetamine consumption was almost double that in other groups [ 22 , 25 ]. A more comprehensive and multidisciplinary approach to chemsex could avoid considerable individual and public health issues beyond HIV transmission [ 45 , 46 ].…”

Post-Exposure Prophylaxis and Methamphetamine Use among Young Sexual Minority Men: The P18 Cohort Study

“…In a NYC survey, 41% of SMM had heard of PrEP, but only 3.4% of the sample had ever taken it [ 5 ]; in general, PrEP uptake rates are lower among young SMM than older SMM [ 20 ]. Among SMM, researchers found that PrEP awareness was significantly lower for methamphetamine users when compared with those who do not use methamphetamines (89% and 95%, respectively, p = 0.01), but there was no significant difference in actual PrEP use between the two groups [ 21 ].…”

An update on drug–drug interactions between antiretroviral therapies and drugs of abuse in HIV systems

“…In the United States alone, prevalence of meth use among PLWHA was over 9% during 2015-2016 [86]. As per the National HIV Behavioral Surveillance (NHBS) 2017 survey from Seattle, WA; Portland, OR; and Denver, CO which involved 1,602 meth users, particularly men who have sex with men (MSM), and at substantial risk of HIV, reported that meth use most likely was the cause for low oral-preexposure prophylaxis (PrEP) awareness among the risk group [87]. Similar observations were noticed in a longitudinal study of the Swiss HIV Cohort performed during 2007-2017 where use of psychostimulants, including meth, was significantly associated with unsafe sex with frequent partners, and higher prevalence of mood disorders, sexually transmitted infections, and viral infections other than HIV [88].…”
