Consistency and change in club drug use by sexual minority men in New York City, 2002 to 2007

PrEP Uptake and Methamphetamine Use Patterns in a 4-Year U.S. National Prospective Cohort Study of Sexual and Gender Minority People, 2017-2022

Methamphetamine use is on the rise among sexual and gender minority people who have sex with men (SGMSM), escalating their HIV risk. Despite pre-exposure prophylaxis (PrEP) being an effective biomedical HIV prevention tool, its uptake in relation to methamphetamine use patterns in SGMSM has not been studied. In a U.S. cohort study from 2017 to 2022, 6,253 HIV-negative SGMSM indicated for but not using PrEP were followed for four years. Methamphetamine use was categorized (i.e., newly initiated, persistently used, never used, used but quit), and PrEP uptake assessed using generalized estimating equation (GEE), adjusted for attrition. Participants had a median age of 29, with 51.9% White, 11.1% Black, 24.5% Latinx, and 12.5% other races/ethnicities. Over the four years, PrEP use increased from 16.3 to 27.2%. GEE models identified risk factors including housing instability and food insecurity. In contrast, older age, health insurance, clinical indications, and prior PrEP use increased uptake. Notably, Latinx participants were more likely to use PrEP than Whites. Regarding methamphetamine use, those who newly initiated it were more likely to use PrEP compared to non-users. However, those who quit methamphetamine and those who persistently used it had PrEP usage rates comparable to those of non-users. Though PrEP uptake increased, it remained low in SGMSM. Methamphetamine use was associated with PrEP uptake. Healthcare providers should assess methamphetamine use for harm reduction. Prioritizing younger, uninsured SGMSM and addressing basic needs can enhance PrEP uptake and reduce HIV vulnerabilities.

Motivational Enhancement Interventions to Increase Pre-Exposure Prophylaxis Use in Sexual Minority Men Who Use Stimulants: Protocol for a Pilot Sequential Multiple Assignment Randomized Trial

BACKGROUND

Although pre-exposure prophylaxis (PrEP) could substantially mitigate HIV risk, sexual minority men who use stimulants commonly experience difficulties with engaging in PrEP clinical services. Motivational interviewing (MI) and contingency management (CM) reduce substance use and condomless anal sex (CAS) in this population, but these motivational enhancement interventions require modifications to promote engagement along the PrEP care continuum.

OBJECTIVE

PrEP Readiness Interventions for Supporting Motivation (PRISM) is a pilot sequential multiple assignment randomized trial testing the feasibility, acceptability, and preliminary effectiveness of distinct combinations of telehealth MI and CM in 70 cisgender sexual minority men who use stimulants that are not currently taking PrEP.

METHODS

A national sample was recruited via social networking applications to complete a baseline assessment and mail-in HIV testing. Those with nonreactive HIV results were randomized to receive either (1) a 2-session MI intervention focusing on PrEP use (session 1) and concomitant stimulant use or CAS (session 2) or (2) a CM intervention with financial incentives for documented evidence of PrEP clinical evaluation by a medical provider (US $50) and filling a PrEP prescription (US $50). At the 3-month follow-up assessment, participants who reported they had not filled a prescription for PrEP were randomized a second time to either (1) switch to a second-stage intervention (ie, MI+CM or CM+MI) or (2) continue with assessments only. Outcomes for both responders and nonresponders were reassessed at a 6-month follow-up. The primary outcome is documented evidence of filling a PrEP prescription over 6 months. Self-reported secondary outcomes include PrEP clinical evaluation by a medical provider, stimulant use, and CAS. Qualitative exit interviews were conducted with a subgroup of responders and nonresponders to characterize their experiences with the MI and CM interventions.

RESULTS

Implementation of PRISM underscores challenges in reaching sexual minority men who use stimulants to optimize HIV prevention efforts. Approximately 1 in 10 (104/1060) eligible participants have enrolled. Of the 104 who enrolled, 87 (84%) completed mail-in HIV testing. We delivered 5 preliminary HIV-positive results, including posttest counseling with referrals to confirmatory testing.

CONCLUSIONS

Lessons learned from PRISM underscore the central importance of a flexible, participant-centered approach to support the engagement of sexual minority men who use stimulants. Leveraging telehealth platforms to deliver motivational enhancement interventions also expanded their reach and potential public health impact with this high-priority population. Further research is needed to determine the effectiveness of telehealth MI and CM for supporting PrEP use in sexual minority men who use stimulants.

Randomized Controlled Trial of Motivational Enhancement Interventions to Increase Pre-Exposure Prophylaxis Use in Sexual Minority Men Who Use Stimulants

Background

Although pre-exposure prophylaxis (PrEP) could substantially mitigate HIV risk, sexual minority men (SMM) who use stimulants commonly experience difficulties with engaging in PrEP clinical services. Motivational interviewing (MI) and contingency management (CM) reduce substance use and condomless anal sex in this population, but these motivational enhancement interventions require adaptation to promote engagement along the PrEP care continuum.

Methods

PRISM is a pilot sequential multiple assignment randomized trial (SMART) testing the feasibility, acceptability, and preliminary effectiveness of distinct combinations of telehealth MI and CM in 70 cisgender SMM who use stimulants that are not currently taking PrEP. A national sample was recruited via social networking applications to complete a baseline assessment and mail-in HIV testing. Those with non-reactive HIV results are randomized to receive either: 1) a 2-session MI intervention focusing on PrEP use (session 1) and concomitant stimulant use or condomless anal sex (session 2); or 2) a CM intervention with financial incentives for documented evidence of PrEP clinical evaluation by a medical provider ($50) and filling a PrEP prescription ($50). At the 3-month follow-up assessment, participants who report they have not filled a prescription for PrEP are randomized a second time to either: 1) Switch to a second-stage intervention (i.e., MI + CM or CM + MI); or 2) Continue with assessments only. Outcomes for both responders and non-responders are reassessed at a 6-month follow-up. The primary outcome is documented evidence of filling a PrEP prescription. Self-reported, secondary outcomes include PrEP clinical evaluation by a medical provider, stimulant use, and condomless anal sex. Qualitative exit interviews are conducted with a sub-group of responders and non-responders to characterize their experiences with the MI and CM interventions.

Discussion

Implementation of this pilot SMART underscores the challenges in reaching SMM who use stimulants to optimize HIV prevention efforts such that approximately one in ten (104/1,060) eligible participants enrolled. However, 85% (70/82) of enrolled participants with non-reactive HIV results were randomized. Further research is needed to determine the effectiveness of telehealth MI and CM for supporting PrEP use in SMM who use stimulants.

The Tsunamic Model of LGBTQ+ Deaths of Despair: A Systemic Review to Identify Risk Factors for Deaths of Despair Among LGBTQ+ People

The term Deaths of Despair (DOD) was introduced to capture the phenomenon of mortality associated with suicide, drug overdose, and alcoholic liver disease. The LGBTQ+ population consistently evidences disproportionately high rates of DOD. This study reviewed the literature on DOD within this community to create a conceptual model that identifies risk factors that work together to potentiate DOD in the LGBTQ+ community. Ten DOD-Related Factors were identified and used to create The Tsunamic Model of LGBTQ+ Deaths of Despair. DOD-Related Factors include: (1) Stigma, (2) Demographics, (3) Identity Development, (4) Internalized Homophobia, (5) Depression, (6) Victimization, (7) Isolation/Rejection, (8) Sensation Seeking, (9) Risky Behavior, and (10) Uninformed Care. Each factor is associated with increased risk for DOD among the LGBTQ+ community. This model can help health professionals by providing a framework for prevention and early intervention programs.

Running with Scissors: a Systematic Review of Substance Use and the Pre-exposure Prophylaxis Care Continuum Among Sexual Minority Men

Purpose of Review

Patterns of sexualized drug use, including stimulants (e.g., methamphetamine) and chemsex drugs, are key drivers of HIV incidence among sexual minority men (SMM). Although pre-exposure prophylaxis (PrEP) mitigates HIV risk, there is no consensus regarding the associations of substance use with the PrEP care continuum.

Recent Findings

SMM who use substances are as likely or more likely to use PrEP. Although SMM who use stimulants experience greater difficulties with daily oral PrEP adherence, some evidence shows that SMM who use stimulants or chemsex drugs may achieve better adherence in the context of recent condomless anal sex. Finally, SMM who use substances may experience greater difficulties with PrEP persistence (including retention in PrEP care).

Summary

SMM who use stimulants and other substances would benefit from more comprehensive efforts to support PrEP re-uptake, adherence, and persistence, including delivering behavioral interventions, considering event-based dosing, and providing injectable PrEP.

Changes in substance use among HIV-negative MSM: A longitudinal analysis, 1995-2019

BACKGROUND

Research suggests shifting patterns of recreational drug consumption among MSM in recent decades. The present study evaluates population-level mean trajectories of substance use among HIV-negative MSM from 1995 to 2019.

METHODS

Using open cohort study data following MSM in the Netherlands (n=1495) since 1995, we applied generalized estimating equations to examine population-averaged estimates of five substances - alcohol, cannabis, ecstasy, cocaine, and poppers - from 1995 to 2019, as well as their use during sexual encounters.

RESULTS

Recent alcohol use decreased; predicted probabilities declined from 1995 to 2019 (.96 to .87). During the same period, cocaine and poppers use increased - (.10 to .23 and .37 to .47, respectively) and use during sex also increased (.05 to .16, and .32 to .41, respectively). Ecstasy use increased over time (.23 to .38), although not during sex. No significant changes in cannabis use occurred.

CONCLUSIONS

While changes in use of various substances were mixed, increases in cocaine and poppers use during sexual encounters occurred among HIV-negative MSM over time. Efforts to intervene on substance use in connection with sex remain critical for health promotion.

HIV-1 and methamphetamine alter galectins -1, -3, and -9 in human monocyte-derived macrophages

Macrophages are key elements of the innate immune system. Their HIV-1 infection is a complex process that involves multiple interacting factors and various steps and is further altered by exposure of infected cells to methamphetamine (Meth), a common drug of abuse in people living with HIV. This is reflected by dynamic changes in the intracellular and secreted proteomes of these cells. Quantification of these changes poses a challenge for experimental design and associated analytics. In this study, we measured the effect of Meth on expression of intracellular and secreted galectins-1, -3, and -9 in HIV-1 infected human monocyte-derived macrophages (hMDM) using SWATH-MS, which was further followed by MRM targeted mass spectrometry validation. Cells were exposed to Meth either prior to or after infection. Our results are the first to perform comprehensive quantifications of galectins in primary hMDM cells during HIV-1 infection and Meth exposure a building foundation for future studies on the molecular mechanisms underlying cellular pathology of hMDM resulting from viral infection and a drug of abuse—Meth.

Associations of prescription stimulant misuse with subsequent methamphetamine use among a U.S. cohort of HIV-vulnerable sexual and gender minorities who have sex with men

INTRODUCTION

Prescription stimulants and methamphetamine have similarities in chemical structure and impact on biological functioning. However, there is limited literature on prescription stimulant misuse among sexual and gender minorities as well as how prescription misuse may impact later methamphetamine use.

METHODS

We used data collected from a HIV prevention cohort to describe (e.g., frequencies, percentages) prescription stimulant use/misuse and methamphetamine use at baseline and 12-month follow-up (n = 4857). We then used multivariable logistic regression models to determine the impact of baseline prescription stimulant misuse and methamphetamine use on 12-month prescription stimulant misuse and methamphetamine use.

RESULTS

At baseline, 10.2 % of participants misused prescription stimulants and 12 % of participants used methamphetamine in the past 3 months, while at 12-month follow-up 11.6 % of participants misused prescription stimulants and 11.2 % of participants used methamphetamine in the past 3 months. Multivariable regression analyses indicated that participants who misused prescription stimulants (in the absence of methamphetamine) at baseline had 2.51 (95 % CI: 1.44-3.59, ref. no stimulant or methamphetamine use) times the odds of using methamphetamine at 12-month follow-up.

DISCUSSION

Findings suggest that prescription stimulant use is a risk factor for continued meth use. Therefore, earlier and targeted public health interventions could reduce methamphetamine use by disrupting the progression from prescription stimulant misuse to methamphetamine use through early screening and interventions for prescription stimulant misuse.

Day-level associations between drug use and sexual behavior in male couples: Actor partner interdependence modeling of timeline follow-back data

BACKGROUND

Both marijuana and other illicit drugs (e.g., cocaine/crack, methamphetamines, ecstasy, gamma-hydroxybuterate, and ketamine) have been linked to the occurrence of condomless anal sex (CAS) with casual partners among sexual minority men (SMM) and these associations largely generalize to partnered SMM. Software advances now permit testing the day-level correspondence between participants' sexual behavior and their own drug use (actor effects) as well as their partners' (partner-effects).

METHODS

Participants comprised 50 couples (100 individuals) recruited in the New York City metro area. All were 18 or older and identified as cis male. In each couple, at least one partner was 18-29 years old, HIV-negative, reported recent (past 30 day) drug use and recent (past 30 day) CAS with a casual partner or CAS with a non-monogamous or sero-discordant main partner at screening.

RESULTS

Marijuana was associated with CAS between main partners on days both partners reported its use. A similar pattern was observed for other illicit drugs. Respondents were more likely to report CAS with casual partners on days CAS between main partners occurred. Both marijuana and other illicit drugs were associated with increased likelihood of CAS with casual partners on days a main partner did not use drugs. These associations were attenuated on days where partners reported the use of different drugs.

CONCLUSIONS

The co-occurrence of CAS with main and casual partners maximizes shared sexual risk. Results support the continued emphasis on dyadic HIV prevention interventions and the development of theoretically-based interventions that may address drug use by both partners in the relationship.

Trends in Methamphetamine Use Among Men Who Have Sex with Men in New York City, 2004-2017

Methamphetamine (meth) use among men who have sex with men (MSM) has been documented to be associated with HIV transmission among those who are HIV-negative and worsening HIV outcomes among those who are HIV-positive. Recent media reports have suggested recent increases in meth use in New York City (NYC), particularly among Hispanic/Latino and Black MSM. Using serial cross-sectional data from 2004 to 2017, we aim to describe trends in meth use and describe racial/ethnic patterns among MSM in NYC. Overall, we observed a decrease in meth use among MSM from 2004 to 2011 and an increase from 2011 to 2017. When stratified by race/ethnicity, use among White MSM decreased. Beginning in 2008, use among both Hispanic/Latino and Black MSM increased over time. These data provide more evidence that meth use may be increasing in Hispanic/Latino and Black MSM. Culturally-tailored and status-neutral interventions should be explored.

The Crisis We Are Not Talking About: One-in-Three Annual HIV Seroconversions Among Sexual and Gender Minorities Were Persistent Methamphetamine Users

INTRODUCTION

Methamphetamine use is once again on the rise among sexual and gender minorities who have sex with men (SGMSM).

METHODS

Baseline and 12-month data are taken from an ongoing cohort study of n = 4786 SGMSM aged 16-49 at risk for HIV from across the United States. Participants completed annual online surveys and at-home HIV testing (oral fluid samples returned through mail).

RESULTS

Overall, 2.47 per 100 persons seroconverted over 12 months. In addition, 13.8% of participants reported any methamphetamine use over the 12-month study period. Nearly three-fourths (74.7%; 422 of 565) of those who reported using methamphetamine at baseline were persistent users at 12 months. In adjusted analyses, compared with those who did not use methamphetamine, incident methamphetamine users (ie, those who indicated use between baseline and follow-up) and persistent methamphetamine users had significantly higher odds of HIV seroconverting (adjusted odds ratio = 3.95, 95% confidence interval: 1.64 to 9.47; and 7.11, 4.53 to 11.17, respectively). Persistent methamphetamine users accounted for one-third of all observed HIV seroconversions (41 of 115).

DISCUSSION

Among SGMSM at elevated risk for HIV, persistent methamphetamine use was prevalent and associated with substantially amplified risk for HIV seroconversion. Expanded efforts are needed to test implementation strategies for scalable, evidence-based interventions to reduce HIV risk in SGMSM who use methamphetamine.

Higher and Higher? Drug and Alcohol Use and Misuse among HIV-Vulnerable Men, Trans Men, and Trans Women Who Have Sex with Men in the United States

BACKGROUND

Substance use (SU) and misuse are disproportionately more common among sexual and gender minority (SGM) individuals compared to their heterosexual peers. Yet, little is known about regional and demographic differences in use and misuse among SGM. In this study, we investigated regional and demographic differences in SU and misuse in a U.S. national, internet-based cohort (n = 6,280) of men and trans persons who have sex with men. Methods: Data collected included the WHO ASSIST (substance) and AUDIT (alcohol) SU scales to estimate recent (≤ 3 months) non-problematic use (≤ 3 ASSIST, ≤ 10 AUDIT) and misuse (≥4 ASSIST, ≥11 AUDIT). We used bivariate and multivariable logistic models to examine demographic and regional factors associated with SU and misuse. Results: Participants reported using alcohol (85.6%), cannabis (53.9%), and inhalants (39.1%) in the past three months. More than one-third self-reported misuse of cannabis, Gamma-Hydroxybutyrate (GHB), inhalants, methamphetamines, and prescription sedatives. We observed regional differences in substance use for cannabis (Southeast aOR = 0.76, 95% CI: 0.63-0.93; West aOR = 1.27, 95% CI: 1.02-1.59, ref. Northeast) and prescription Stimulants (Midwest aOR = 1.39, 95% CI: 1.00-1.93), as well as for cannabis misuse (Southeast aOR = 0.83, 95% CI: 0.69-0.99). We also observed significant associations between socioeconomic factors with use and misuse. Conclusions: Findings suggest geographic differences in misuse of certain substances among men and trans persons who have sex with men in the US, and that socio-economic factors, also play a key role in indicating risk.

Factors Associated with Drug Use Among HIV-Infected Men Who Have Sex with Men in China

Drug use is globally more prevalent in HIV-positive men who have sex with men (HIVMSM) than their heterosexual counterparts. Yet, few studies have investigated the factors associated with drug use among this population beyond Western societies. A cross-sectional survey was conducted to examine factors associated with drug use among 415 HIVMSM in Chengdu, China. The results show that 10.8% of the participants had used drugs in the past 30 days. Among participants who had anal intercourse in the past 30 days, 11.5% had used drugs during anal intercourse. After adjusting for background variables, logistic regression models show that life satisfaction was associated with past 30-day drug use [Adjusted Odds Ratio (ORa) = 0.90, p < 0.001], and with drug use during anal intercourse in the past 30 days (ORa = 0.89, p < 0.01). Participants with more nonregular partners were more likely to use drugs with or without sex in the past 30 days, whereas those with one regular partner were less likely to use drugs during anal intercourse compared to their counterparts with no regular partners. The findings of this study are informative for designing effective substance-use intervention programs targeting HIVMSM.

Determining the Roles that Club Drugs, Marijuana, and Heavy Drinking Play in PrEP Medication Adherence Among Gay and Bisexual Men: Implications for Treatment and Research

Researchers have established that substance use interferes with anti-retroviral medication adherence among gay and bisexual men (GBM) living with HIV. There is limited parallel examination of pre-exposure prophylaxis (PrEP) adherence among HIV-negative GBM. We conducted retrospective 30-day timeline follow-back interviews and prospective semi-weekly diary data for 10 weeks with 104 PrEP-using GBM, half of whom engaged in club drug use (ketamine, ecstasy, GHB, cocaine, or methamphetamine)-generating 9532 days of data. Participants reported their day-by-day PrEP, club drug, marijuana, and heavy alcohol use (5 + drinks in one sitting). On average, club drug users were no more likely to miss a dose of PrEP than non-club drug users (M = 1.6 doses, SD = 3.0, past 30 days). However, we found that club drug use (at the event level) increased the odds of missing a dose on the same day by 55% and the next day (e.g., a "carryover effect") by 60%. Further, missing a dose on one day increased the odds of missing a dose the following day by eightfold. We did not identify an event-level effect of marijuana use or heavy drinking on PrEP adherence. Our data suggest club drug users could have greater protective effects from daily oral or long-acting injectable PrEP compared to a time-driven PrEP regimen because of the concurrence of club drug use and PrEP non-adherence.

Testing the Efficacy of Combined Motivational Interviewing and Cognitive Behavioral Skills Training to Reduce Methamphetamine Use and Improve HIV Medication Adherence Among HIV-Positive Gay and Bisexual Men

Prior research has identified subgroups of HIV-positive gay and bisexual men (GBM) based upon information, motivation, and behavioral skills (IMB) profiles related to HIV medication adherence and methamphetamine use. We conducted a randomized controlled trial of a combined motivational interview (MI) and cognitive behavioral therapy (CBT) intervention tailored specifically to the unique context of HIV-positive GBM, and tested whether IMB profiles moderated treatment effects. HIV-positive GBM (N = 210) were randomized to MI + CBT or an attention-matched education control. Both conditions resulted in reduced methamphetamine use, improved medication adherence (and higher CD4 and lower viral loads), and fewer acts of condomless anal sex at 3, 6, 9 and 12 months post-intervention. Furthermore, the MI + CBT condition achieved greater improvements in medication adherence for men who had greater barriers to change compared to similarly-classified men in the control condition, suggesting the importance of pre-intervention profiles for tailoring future interventions.

Time Since First Acting on Same-Sex Attraction and Recreational Drug Use among Men Who Have Sex With Men (MSM): Is There an Effect of "Gay Age"?

BACKGROUND

Men who have sex with men (MSM) have higher rates of substance use compared to men who have sex with women. Among MSM, drug use is linked to higher-risk sexual behavior and acquisition of HIV and other sexually transmitted infections.

OBJECTIVES

We hypothesize that time since first acting on one's same sex attraction, or one's "gay age", could be predictive of drug using behavior.

METHODS

We examined this question among 176 MSM, aged 18-35, presenting at a public sexual health clinic. Behavioral data were captured using interviewer- and self-administered surveys and clinical data were extracted from medical records. We used modified Poisson regression to examine associations between gay age and recent recreational drug use, and separately, between gay age and recent marijuana use.

RESULTS

In total, 43% of participants reported recent marijuana use and 26% of participants reported recent use of other drugs. The associations between gay age and marijuana use and other drug use varied by HIV status. After adjustment for biological age, race, and education, a one-year increase in gay age was associated with significantly increased drug use among HIV-negative men (adjusted prevalence ratio (aPR): 1.08; 95% confidence interval (CI): 1.03-1.14), but we observed no association between gay age and drug use among HIV-positive men (aPR: 0.96, 95% CI: 0.86-1.07). Gay age was not associated with marijuana use in HIV-negative (aPR: 1.00, 95% CI: 0.95-1.04) or HIV-positive (aPR: 1.06, 95% CI: 0.98-1.14) men.

CONCLUSIONS

In summary, HIV-negative MSM who had experienced more time since first same-sex experience had significantly increased prevalence of recent drug use.

A Study of the Longitudinal Patterns of Stimulant and Amyl Nitrite Use and Sexual Behavior Pre- and Post-HIV Seroconversion Among MSM

The use of stimulant drugs alone or in combination with amyl nitrites (stimulant/nitrites) has been associated with higher rates of risky sexual behavior and predictive of HIV infection among men who have sex with men. However, the temporal pattern of stimulant/nitrite use pre- and post-seroconversion has not been well established. This study assessed changes in stimulant/nitrite use and risky sexual behavior among seroconverting MSM over time. Data were collected in the Baltimore-Washington, DC; Pittsburgh; Chicago; and Los Angeles sites of the Multicenter AIDS Cohort Study (MACS), a longitudinal study of the natural history of HIV infection among MSM. We used propensity scores to select 1044 MSM from 7087 MACS participants composed of 348 seroconverting, 348 seronegative, and 348 seroprevalent participants matched on demographics, recruitment cohort, and study visits. We centered up to four-years of semi-annual data around the seroconversion visit of the seroconverting case within each matched group of participants. Mixed effects regressions estimated the effects of serostatus, recruitment cohort, and time on self-reported stimulant/nitrite use, numbers of male intercourse partners, and numbers of unprotected receptive anal intercourse (URAI) partners. Covariates included demographics, binge drinking, and marijuana use. Seroconverters had the highest odds of stimulant/inhaled nitrite use (AOR 10.3, CI 4.8-22.0), incident rates of intercourse (IRR 1.6, CI 1.3-2.1), and URAI partners (IRR 5.1, CI 3.5-7.3). All participants decreased drug use and sexual risk behavior over time. However, the decreases were largest for seroconverters who nevertheless maintained the highest rates of stimulant/nitrite use and sexual risk. Cohort-related effects were associated with sharp reductions in stimulant/nitrite use and URAI in the early 1990s that rebounded considerably within the first decade of the 2000s. Although all participants decreased risky sexual behavior and stimulant and/or nitrite use over time, seroconverters had the largest decreases. There was no evidence for abrupt or substantial increases in drug use or risky sex post-seroconversion. However, there was substantial variation at the individual level, with the factors underlying this variation not well understood and worth further study. Moreover, stimulant/nitrite use and risky sexual behavior appear to have been strongly influenced by contextual historical and socio-cultural effects. The manner in which contextual factors influence individual behavior is also not well understood and also warrants further study.

Polysubstance use profiles among electronic dance music party attendees in New York City and their relation to use of new psychoactive substances

BACKGROUND

Electronic Dance Music (EDM) party attendees are often polysubstance users and are at high risk for use of new psychoactive substances (NPS). We sought to identify patterns of use of common illegal drugs among EDM party attendees, sociodemographic correlates, and use of NPS as a function of patterns of use of more common drugs to inform prevention and harm reduction.

METHOD

Using time-space-sampling, 1045 individuals aged 18-40 were surveyed entering EDM parties in New York City. We queried past-year use of common illegal drugs and 98 NPS. We conducted latent class analysis to identify polysubstance use profiles of use of eight common drugs (i.e., ecstasy, ketamine, LSD, mushrooms, powder cocaine, marijuana, amphetamine, benzodiazepines). Relationships between drug classification membership and sociodemographics and use of drugs within six NPS categories were examined.

RESULTS

We identified four profiles of use of common drugs: non-polysubstance use (61.1%), extensive polysubstance use (19.2%), moderate polysubstance use/stimulants (12.8%), and moderate polysubstance use/psychedelics (6.7%). Those in the moderate/psychedelic group were at higher odds of using NPS with psychedelic-type effects (2C, tryptamines, and other "new" psychedelics; Ps<0.05). Extensive polysubstance users were at increased odds of reporting use of 2C drugs, synthetic cathinones ("bath salts"), tryptamines, other new (non-phenethylamine) psychedelics, new dissociatives, and synthetic cannabinoids (Ps<0.05).

CONCLUSION

NPS preference is linked to the profile of use of common drugs among individuals in the EDM scene. Most participants were identified as non-polysubstance users, but findings may help inform preventive and harm reduction interventions among those at risk in this scene.

Feasibility of an Emotion Regulation Intervention to Improve Mental Health and Reduce HIV Transmission Risk Behaviors for HIV-Positive Gay and Bisexual Men with Sexual Compulsivity

Gay and bisexual men (GBM) report high rates of sexual compulsivity (SC), yet no empirically based treatments exist. An intervention based on the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders was pilot tested in a sample of 13 HIV-positive GBM with SC. Participants completed a baseline interview, and were offered up to ten intervention sessions. Of those, 11 completed a 3-month follow-up assessment. Despite problems with session attendance (only 4 men completed all 10 sessions), improvements were observed in all psychological outcomes, including SC, depression, and anxiety. Decreases were observed in drug use and HIV risk. The Unified Protocol may be useful in improving the health of HIV-positive GBM, however challenges with session attendance must be addressed. Future work should consider if fewer sessions produce similar results, whether barriers to attending all sessions could be alleviated, and how the intervention would perform compared to treatments.

Preintervention Profiles of Information, Motivational, and Behavioral Self-Efficacy for Methamphetamine Use and HIV Medication Adherence Among Gay and Bisexual Men

Although rates of crystal methamphetamine use in the United States have fallen from their peak in the mid-2000s, use remains a major public health concern, which disproportionately affects gay and bisexual men (GBM). It poses a particular challenge for HIV-positive men, for whom it has been linked to medication adherence problems as well as compromised immune function. Although the information, motivation, and behavioral skills (IMB) model has been widely used to conceptualize health behavior, little is known about GBM's initial levels of information, motivation, and behavioral self-efficacy to improve HIV medication adherence and to reduce crystal methamphetamine use at the outset of treatment. The present study identified profiles of IMB factors related to HIV medication adherence and crystal methamphetamine use in a sample of 210 HIV-positive GBM who consented to participate in an intervention study. Results indicated three distinct patterns of IMB factors. The largest group was ready to change both adherence and methamphetamine use (n = 104). This group also had depression scores that were significantly lower than other groups. A second group appeared ready to change medication adherence, but was ambivalent about changing methamphetamine use (n = 60). This group reported significantly more symptoms of methamphetamine dependence than the other groups. A third group was characterized by global IMB barriers to change (n = 46). Results are discussed in the context of tailoring psychoeducation, motivational interviewing, and cognitive behavioral interventions to match these preintervention patterns of IMB factors.

Effects of HIV and Methamphetamine on Brain and Behavior: Evidence from Human Studies and Animal Models

Methamphetamine (Meth) use is frequent among HIV-infected persons. Combined HIV and Meth insults may exacerbate neural injury in vulnerable neuroanatomic structures or circuitries in the brain, leading to increased behavioral disturbance and cognitive impairment. While acute and chronic effects of Meth in humans and animal models have been studied for decades, the neurobehavioral effects of Meth in the context of HIV infection are much less explored. In-depth understanding of the scope of neurobehavioral phenotypes and mechanisms in HIV/Meth intersection is needed. The present report summarizes published research findings, as well as unpublished data, in humans and animal models with regard to neurobehavioral disturbance, neuroimaging, and neuropathology, and in vitro experimental systems, with an emphasis on findings emerging from the National Institute on Drug Abuse (NIDA) funded Translational Methamphetamine AIDS Research Center (TMARC). Results from human studies and animal (primarily HIV-1 gp120 transgenic mouse) models thus far suggest that combined HIV and Meth insults increase the likelihood of neural injury in the brain. The neurobehavioral effects include cognitive impairment and increased tendencies toward impaired behavioral inhibition and social cognition. These impairments are relevant to behaviors that affect personal and social risks, e.g. worse medication adherence, riskier behaviors, and greater likelihood of HIV transmission. The underlying mechanisms may include electrochemical changes in neuronal circuitries, injury to white matter microstructures, synaptodendritic damage, and selective neuronal loss. Utilization of research methodologies that are valid across species is instrumental in generating new knowledge with clinical translational value.

Differences in Relationship Characteristics Between HIV-Negative Male Couples Who Used and Did Not Use Substances with Sex

Although substance use is linked to HIV seroconversion, little is known about male couples substance use with sex. The present study sought to: describe whether neither, one, or both partners in the couple used a particular substance with sex within or outside their relationship; assess, by substance type used with sex, whether relationship factors differed between these groups of couples. Dyadic data from 83 behaviorally non-monogamous HIV-negative male couples were used with multinomial regression models. Those who used with sex within the relationship varied by substance type; outside the relationship, most only had one partner who used with sex. Couples with one or both partners who used substances with sex within or outside the relationship were more likely to have higher commitment to their relationship yet less likely to trust their main partner; mixed results were found regarding communication. Further research is warranted toward the need for preventive intervention development.

Illicit drug use among rave attendees in a nationally representative sample of US high school seniors

BACKGROUND

The popularity of electronic dance music and rave parties such as dance festivals has increased in recent years. Targeted samples of party-goers suggest high rates of drug use among attendees, but few nationally representative studies have examined these associations.

METHODS

We examined sociodemographic correlates of rave attendance and relationships between rave attendance and recent (12-month) use of various drugs in a representative sample of US high school seniors (modal age: 18) from the Monitoring the Future study (2011-2013; Weighted N=7373).

RESULTS

One out of five students (19.8%) reported ever attending a rave, and 7.7% reported attending at least monthly. Females and highly religious students were less likely to attend raves, and Hispanics, students residing in cities, students with higher income and those who go out for fun multiple times per week were more likely to attend. Rave attendees were more likely than non-attendees to report use of an illicit drug other than marijuana (35.5% vs. 15.6%, p<0.0001). Attendees were more likely to report use of each of the 18 drugs assessed, and attendees were more likely to report more frequent use (≥6 times) of each drug (ps<0.0001). Controlling for sociodemographic covariates, frequent attendance (monthly or more often) was associated with higher odds of use of each drug (ps<0.0001). Frequent attendees were at highest risk for use of "club drugs."

DISCUSSION

Findings from this study can help inform prevention and harm reduction among rave attendees at greatest risk for drug use.

Crystal methamphetamine use and HIV medical outcomes among HIV-infected men who have sex with men accessing support services in New York

BACKGROUND

Drug use poses multiple challenges to maintaining physical health among HIV-infected individuals, particularly with regard to disease progression. Few studies, however, have examined the association between the use of crystal methamphetamine ("crystal meth") and HIV disease progression specifically among HIV-infected men who have sex with men (MSM). Understanding this relationship among HIV-infected MSM is particularly critical because of the high rates of crystal meth use reported in the population.

METHODS

Associations between recent crystal meth use and poor HIV medical outcomes (viral load>200 copies/mL, CD4 count <350 cells/mm(3)) were analyzed for 2896 HIV-infected MSM enrolled in Ryan White Part A programs in the greater New York metropolitan area between November 2010 and June 2012.

RESULTS

Crystal meth use (reported by 4%) was independently associated with unsuppressed viral load (AOR=1.8, CI=1.1-2.9) in multivariate analyses controlling for sociodemographic characteristics. There was no significant relationship between crystal meth use and low CD4 counts.

CONCLUSIONS

To date, little research has examined how crystal meth use influences HIV medical outcomes among HIV-infected MSM. This analysis showed a significant independent association between crystal meth use and unsuppressed viral load among MSM in an HIV service population. Future studies should examine biological and psychosocial mediators, moderators and confounders of this relationship to inform intervention development for MSM crystal meth users in HIV care settings.

Relationship characteristics differ based on use of substances with sex among an urban internet sample of HIV-discordant and HIV-positive male couples

Previous research with men who have sex with men (MSM) has found that substance use with sex is strongly associated with HIV acquisition and poor adherence to HIV treatments. Although some studies have assessed male couples' use of substances with unprotected anal sex, little is known on whether differences in their relationship dynamics are associated with their usage. Current HIV prevention initiatives underscore the importance of studying male couples' relationship dynamics. Using dyadic data from 28 HIV-positive and 58 HIV-discordant male couples, this analysis sought to: (1) describe, by substance type, whether neither, one, or both partners in the couple used a particular substance with sex within their relationship or outside of the relationship, respectively, and (2) assess, by substance type, whether relationship characteristic differences existed between these three groups of couples with respect to substance use with sex within and outside the relationship. Data from 86 dyads came from a cross-sectional, Internet study. Multivariate multinomial regression models were employed to achieve the aims. Except for alcohol, most did not use substances with sex. Within the relationship, those who used with sex varied by substance type; outside the relationship, most couples had only one partner who used with sex regardless of substance type. Several relationship characteristic differences were noted between the groups of couples. Within the relationship, marijuana and erectile dysfunction medication (EDM) use with sex was associated with having less tangible resources; for outside the relationship, these were associated with perceiving to have greater quality of alternatives. In general, amyl nitrates and party drug use with sex were associated with viewing the main partner as being less dependable for trustworthiness. Marijuana and party drug use with sex within the relationship and EDM use with sex outside the relationship were negatively associated with being able to communicate constructively. Mixed results were noted for relationship satisfaction. Additional research is urgently needed for prevention and promotion of healthy relationships for male couples who use substances with sex.

Unprotected Anal Intercourse With Casual Male Partners in Urban Gay, Bisexual, and Other Men Who Have Sex With Men

Objectives. We investigated trends in, and predictors of, unprotected anal intercourse (UAI) with casual male partners of gay, bisexual, and other men who have sex with men (GBMSM). Methods. We analyzed data from cross-sectional intercept surveys conducted annually (2003-2008) at 2 large lesbian, gay, and bisexual community events in New York City. Survey data covered GBMSM's highest-risk behaviors for HIV acquisition (HIV-negative or unknown status GBMSM, any UAI) and transmission (HIV-positive GBMSM, any serodiscordant unprotected UAI). Results. Across years, 32.3% to 51.5% of the HIV-negative or unknown status men endorsed any UAI, and 36.9% to 52.9% of the HIV-positive men endorsed serodiscordant UAI. We observed a few statistically significant fluctuations in engagement in high-risk behavior. However, these do not appear to constitute meaningful trends. Similarly, in some years, one or another demographic predictor of UAI was significant. Across years, however, no reliable pattern emerged. Conclusions. A significant proportion of urban GBMSM engage in high-risk sex, regardless of serostatus. No consistent demographic predictors emerged, implying a need for broad-based interventions that target all GBMSM.

Problematic recreational drug use: is there a role for outpatient sexual health clinics in identifying those not already engaged with treatment services?

Background There is an association between recreational drug use, high-risk sexual activity and sexually transmissible infections. Studies have shown a higher prevalence of drug use in those accessing sexual health services; however, there are minimal data on the proportion with problematic recreational drug use. We aimed to understand whether sexual health clinics could identify problematic drug and alcohol use as a novel referral pathway into treatment services. Methods: Males attending two sexual health clinics in London completed questionnaires. Data were collected on demographics; gender of sexual partner; use of alcohol and recreational drugs; if they felt they had problematic use of drugs, alcohol or both; and if they had sought help for their problematic use. Results: In total, 867 males completed the questionnaire; 387 (44.7%) were men who have sex with men (MSM). MSM had significantly higher lifetime use of any drug compared with non-MSM (80.6% vs. 62.5%; P < 0.0001). Thirty-five (4.7%) self-identified problematic drug or alcohol use, with no difference between MSM and non-MSM (6.3% vs. 3.5%; P = 0.08). Of those with problematic drug or alcohol use, 20 were currently or had been engaged with a treatment service and 15 had never engaged with treatment services. MSM were more likely to have ever sought help for drug or alcohol problems compared with non-MSM (P = 0.003). Conclusions: Some individuals attending sexual health clinics with problematic drug use have not engaged with treatment services. It is therefore appropriate to develop screening tools for sexual health clinics to identify these individuals and novel referral pathways to engage them in treatment services.

Differences in Gay Male Couples' Use of Drugs and Alcohol With Sex by Relationship HIV Status

Prior studies with men who have sex with men have documented a strong association between substance use with sex and risk for acquisition of HIV. However, few studies have been conducted about gay male couples' use of substances with sex, despite the fact that between one third and two thirds of men who have sex with men acquire HIV from their relationship partners. The present study sought to (1) describe whether one or both partners in the male couple uses substances with sex-by substance type-within and/or outside of their relationship, and (2) assess whether differences exist in those who use substances with sex within and outside the relationship by the couples' HIV status. Dyadic data for this analysis were collected in the United States from a nation-wide cross-sectional Internet study about male couples' relationships and behaviors. Couple-level descriptive and comparative analyses were employed with 361 male couples. Except for alcohol, most couples did not use substances with sex. Of those who did, rates of who used it with sex and substance type within the relationship varied; most couples only had one partner who used substances with sex outside the relationship. Significantly higher proportions of concordantly HIV-negative and HIV-positive couples had both partners who used substances (all types) with sex within their relationship over discordant couples. Most couples had one partner who used outside the relationship; only marijuana and erectile dysfunction medication use with sex significantly differed by couples' HIV status. Findings indicate the need to conduct additional research for prevention development.

An examination of sociodemographic correlates of ecstasy use among high school seniors in the United States

BACKGROUND

Although ecstasy (MDMA) use is not as prevalent in the United States (US) as it was in the early 2000s, use remains popular among adolescents and young adults. Few recent studies have examined ecstasy use in national samples among those at particularly high risk for use-adolescents approaching adulthood. Research is needed to delineate sociodemographic correlates of use in this group.

METHODS

Data were examined from a nationally representative sample of high school seniors in the US (modal age = 18) from the Monitoring the Future study (years 2007-2012; weighted N = 26,504). Data from all cohorts were aggregated and correlates of recent (last 12-month) use of ecstasy were examined.

RESULTS

Roughly 4.4% of high school seniors reported use of ecstasy within the last year. Females and religious students were consistently at lower odds for use. Black and Hispanic students, and students residing with two parents, were at lower odds for ecstasy use, until controlling for other drug use. Odds of use were consistently increased for those residing in a city, students with weekly income of >$50 from a job, and students earning >$10 weekly from other sources. Lifetime use of alcohol, cigarettes, marijuana, and other illicit drugs each robustly increased odds of ecstasy use.

CONCLUSION

Subgroups of high school seniors, defined by specific sociodemographic factors, and those who have used other drugs, are currently at high risk for ecstasy initiation and use. Since ecstasy is regaining popularity in the US, prevention efforts should consider these factors.

Glutamate receptor antagonists as fast-acting therapeutic alternatives for the treatment of depression: ketamine and other compounds

The N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has rapid and potent antidepressant effects in treatment-resistant major depressive disorder and bipolar depression. These effects are in direct contrast to the more modest effects seen after weeks of treatment with classic monoaminergic antidepressants. Numerous open-label and case studies similarly validate ketamine's antidepressant properties. These clinical findings have been reverse-translated into preclinical models in an effort to elucidate ketamine's antidepressant mechanism of action, and three important targets have been identified: mammalian target of rapamycin (mTOR), eukaryotic elongation factor 2 (eEF2), and glycogen synthase kinase-3 (GSK-3). Current clinical and preclinical research is focused on (a) prolonging/maintaining ketamine's antidepressant effects, (b) developing more selective NMDA receptor antagonists free of ketamine's adverse effects, and (c) identifying predictor, mediator/moderator, and treatment response biomarkers of ketamine's antidepressant effects.

Trends in HIV prevalence and risk behavior among men who have sex with men in New York City, 2004-2011

This study examined trends in HIV prevalence and HIV-related risk behaviors from 2004 through 2011 among men who have sex with men (MSM) in New York City. MSM were venue-sampled, interviewed, and offered HIV testing in serial cross-sectional studies. Significant differences in overall time trends were determined using the Spearman rank correlation and logistic regression models. There were 457 (2004-2005), 550 (2008), and 510 (2011) participants in each study round. There was no significant trend in HIV prevalence over time, and past 12 month unprotected anal intercourse remained steady. However, drug use and number of sex partners declined. Among those who did not self-report being HIV positive, the percentage that tested for HIV in the past 12 months increased. The results from this study suggest that from 2004 through 2011 more MSM in New York City are being tested for HIV and have declining drug use and fewer sex partners.

Drug use and sexual arrangements among gay couples: frequency, interdependence, and associations with sexual risk

Rates of drug use among gay men are higher than their heterosexual counterparts and drug use is a prominent risk factor for HIV transmission. Studies using heterosexual samples have found that being partnered reduces the risk of drug use and individuals in a relationship tend to have similar use patterns. Studies among gay men suggest that sexual agreements may be an important predictor of drug use. Data from 322 partnered gay men were collected and the 161 matched couples were categorized as monogamous (52.8 %), monogamish (14.9 %), open (13.0 %), and discrepant (19.3 %). Patterns of significance and significant trends suggested that monogamous men reported lower rates of marijuana and other drug use compared to open and monogamish men. Men in discrepant relationships did not differ from any other group. Partners' marijuana and other drug use was significantly interdependent in the overall sample; however, substantial variation in the magnitude and significance of interdependence was observed across sexual arrangement categories. Sexual arrangement and the use of drugs during sex both contributed to the prediction of UAI with casual partners among non-monogamous men. Implications for substance use treatment and HIV prevention are discussed.

Prospective predictors of unprotected anal intercourse among HIV-seropositive men who have sex with men initiating antiretroviral therapy

Contemporary HIV prevention efforts are increasingly focused on those already living with HIV/AIDS (i.e., "prevention with positives"). Key to these initiatives is research identifying the most risky behavioral targets. Using a longitudinal design, we examined socio-demographic and psychosocial factors that prospectively predicted unprotected anal intercourse (UAI) in a sample of 134 HIV-seropositive men who have sex with men (MSM) initiating, changing, or re-starting an antiretroviral therapy regimen as part of a behavioral intervention study. Computer-based questionnaires were given at baseline and 6 months. In a sequential logistic regression, baseline measures of UAI (step 1), socio-demographic factors such as Latino ethnicity (step 2), and psychosocial factors such as crystal methamphetamine use, greater life stress, and lower trait anxiety (step 3) were predictors of UAI at 6 months. Problem drinking was not a significant predictor. Prevention efforts among MSM living with HIV/AIDS might focus on multiple psychosocial targets, like decreasing their crystal methamphetamine use and teaching coping skills to deal with life stress.

The psychological cost of anticipating HIV stigma for HIV-negative gay and bisexual men

Much research has examined the impact of HIV-associated stigma on HIV-positive individuals, but little work has explored its impact on HIV-negative persons. However, many gay and bisexual men may imagine the stigma they would experience upon seroconverting, and this anticipated stigma may be associated with negative mental health. Such concerns may be exacerbated among men who identify with the receptive role during anal sex, because of greater risk for infection. This study examined the association between anticipated HIV stigma and negative affect among 683 HIV-negative gay and bisexual men living in New York City. Anticipated HIV stigma predicted negative affect over and above internalized homonegativity. Sexual role identity was associated directly with anticipated stigma and indirectly with negative affect. Results suggest that anticipated HIV stigma may be an important mental health issue for gay and bisexual men. Public health messaging discussing sexual positioning should be sensitive to the potential for exacerbating anticipated HIV stigma among bottom-identified men.

Sometimes you just have to have a lot of bitter to make it sweet: Substance abuse and partner abuse in the lives of HIV+ men who have sex with men

Although links between partner abuse (PA) and substance abuse (SA) are well-documented in the literature, we know less about these relations among HIV-positive men who have sex with men (MSM). We conducted a qualitative study with this group (N = 28). Participants reported (1) social modeling of SA in childhood and in adult social networks, (2) initial use of substance to cope with child abuse and neglect, and (3) the reinforcement of problematic SA by experiences of PA, whereby SA led to PA, resulting in increased SA. Recommendations for clinicians working with HIV+ MSM are discussed.

Rules about casual sex partners, relationship satisfaction, and HIV risk in partnered gay and bisexual men

The authors used latent class analysis to investigate rules guiding nonmonogamy in partnered gay and bisexual men. Data are from a 2010 survey (N = 463) from which those in relationships (n = 191) were analyzed. More than half (56%) were nonmonogamous, and these men responded to 13 rules about sex outside of their relationship. The safe anonymous sex group (34%) included men who indicated that they must use condoms for anal sex and not have sex with people they know. The communication mandate group (19%) included men who indicated that they must talk about outside partners before sex occurs, disclose their relationship status to outside partners, and use condoms for anal sex. The play together group (9%) included men who indicated that they must play with others as a couple, not have anal sex with outside partners, and not spend the night with outside partners. Those in the no salient rule group (37%) were individuals who did not endorse a clear set of rules. These 4 groups (and compared with monogamous men) differed in age, agreement formality and flexibility, relationship satisfaction, and whether anal sex recently occurred with casual partners. This study provides a novel approach for understanding nonmonogamous same-sex relationships and highlights their complexity.

Drug use among gay and bisexual men at weekend dance parties: the role of intentions and perceptions of peers' behaviors

Substance use is high among gay and bisexual men attending weekend dance events, yet little research has investigated motivations for drug use and contextual factors influencing use in these settings. We hypothesized that beliefs about peer drug use interact with individuals' own drug use intentions to predict use. 489 men attending weekend dance events completed an anonymous assessment asking about their own and their beliefs about other attendants' drug use intentions--47 % completed a follow-up assessment after the event. Forty-four percent reported intending to use ecstasy at the event; intentions to use GHB, marijuana, cocaine, unprescribed erectile dysfunction drugs, and poppers were also high. Perceptions about other attendant's drug use predicted use among those intending and those not intending to use drugs. Normative beliefs are important predictors of drug use at weekend dance events; event-specific prevention strategies should encompass messages that correct misperceptions of drug use among party attendants.

Alternatives to monogamy among gay male couples in a community survey: implications for mental health and sexual risk

Researchers have documented the psychological and physical health benefits of being in a relationship among heterosexuals, although there has been limited research to examine such benefits among gay and bisexual men. Gay and bisexual men demonstrate considerable variety in the nature of their relationships, particularly in terms of the degree to which they are monogamous. In order to better understand the psychological and behavioral impact of same-sex relationships on the health of gay and bisexual men, demographic characteristics, psychological factors, sexual behavior, and substance use data were examined in a sample of 819 gay and bisexual men who self-identified as single (n = 503) or were classified as being in monogamous (n = 182), open (n = 71) or monogamish (n = 63) relationships. Monogamish relationships were those in which both men have agreed that any sexual activity with casual partners must happen when both members of the couple are present and involved (e.g., "threeways" or group sex). Findings indicated that being in a same-sex relationship had health benefits compared to being single among gay and bisexual men. Men in monogamous relationships reported the least amount of substance use compared to all other groups, and less substance use during sex than single men or men in open relationships. Men in monogamish relationships demonstrated psychological and sexual health benefits relative to single men and men in open relationships. Gay and bisexual men in monogamish relationships more closely resembled those in monogamous relationships, in terms of psychological and sexual health benefits, rather than men in open relationships, suggesting that varying forms of non-monogamy should be explored for their relevance to health behaviors.

Self-reported penis size and experiences with condoms among gay and bisexual men

As researchers and community-based providers continue to encourage latex condom use as a chief strategy to prevent HIV transmission among men who have sex with men, research is needed to better explore the intersecting associations among penis size (length and circumference), condom feel, ease of finding condoms, recent experience of condom failure (breakage and slippage), and unprotected anal sex. Data were taken from a 2010 community-based survey of self-identified gay and bisexual men in New York City (n = 463). More than half (51.4 %) reported penile length as 6-8 in. long (15-20 cm) and 31.5 % reported penile circumference as 4-6 in. around (10-15 cm). Variation in self-reported penile dimensions was significantly associated with men's attitudes toward the typical/average condom, difficulty finding condoms that fit, and the experience of condom breakage. Men who had engaged in recent unprotected insertive anal intercourse reported significantly higher values for both penile length and circumference, and these men were significantly more likely to report that the average/typical condom was "too tight." Most men had measured their length (86.2 %) and/or circumference (68.9 %), suggesting that penile measurement might be a common and acceptable practice among gay and bisexual men. As HIV and STI prevention providers continue to serve as leading distributers of free condoms, these findings further highlight the need for condom availability to be in a variety of sizes. Improving condom fit and attitudes toward condoms may also improve condom use and minimize condom slippage and breakage.

Recruiting drug using men who have sex with men in behavioral intervention trials: a comparison of internet and field-based strategies

Although online and field-based samples of men who have sex with men (MSM) have been compared on a variety of markers, differences in drug use have not been well examined. In addition, generalization from studies comparing recruitment methods is often limited by a focus on either HIV seropositive or seronegative MSM. We compared two New York City-based samples of MSM recruited simultaneously between July 2009 and January 2010-one sample recruited in the field (n = 2,402) and one sample recruited via the Internet (n = 694). All recruitment efforts targeted men without restriction on age or self-reported HIV status. Our results show marked differences in drug and alcohol use between online and field-based samples of MSM. Specifically, men surveyed online were significantly more likely to have tried a variety of drugs, including methamphetamine, cocaine, and ecstasy. Men recruited online were also more likely to report older age, HIV positive serostatus, and "never" using condoms. Internet-based recruitment was found to be more cost-effective in terms of recruitment yield than was field-based recruitment.

Psychological processes and stimulant use among men who have sex with men

BACKGROUND

Prior research established that psychological factors are associated with the frequency of stimulant (i.e., cocaine, crack, and methamphetamine) use among substance-using men who have sex with men (MSM). The present investigation examined whether and how psychological factors are associated with engagement in any stimulant use in the broader population of MSM.

METHODS

A probability sample of 879 MSM residing in San Francisco was obtained using random digit dialing from May of 2002 through January of 2003. Of these, 711 participants (81%) completed a mail-in questionnaire that assessed psychological factors and substance use. After accounting for demographic factors, a multiple logistic regression analysis examined correlates of any self-reported stimulant use during the past 6 months. Path analyses examined if the use of alcohol or other substances to avoid negative mood states (i.e., substance use coping) mediated the associations of sexual compulsivity and depressed mood with stimulant use.

RESULTS

Younger age (adjusted OR [AOR]=0.58; 95% CI=0.47-0.70), HIV-positive serostatus (AOR=2.55; 95% CI=1.61-4.04), greater depressed mood (AOR=1.26; 95% CI=1.05-1.52) and higher sexual compulsivity (AOR=1.46; 95% CI=1.18-1.80) were independently associated with increased odds of stimulant use. Substance use coping partially mediated the associations of sexual compulsivity (β(indirect)=0.11, p<.001) and depressed mood (β(indirect)=0.13, p<.001) with stimulant use.

CONCLUSIONS

Clinical research is needed to examine if interventions targeting sexual compulsivity and emotion regulation reduce stimulant use among MSM.

A Qualitative Descriptive Study of Perceived Sexual Effects of Club Drug Use in Gay and Bisexual Men

Club drug use is often associated with unsafe sexual practices and use remains prevalent among gay and bisexual men. Although epidemiological studies commonly report the risk of engaging in unsafe sex due to the effects of particular club drugs, there remain gaps in the literature regarding the specific sexual effects of such substances and the context for their use in this population. We examined secondary data derived from interviews with 198 club drug using gay and bisexual males in New York City and qualitatively describe subjective sexual effects of five drugs: ecstasy, GHB, ketamine, powder cocaine and methamphetamine. Differences and commonalities across the five drugs were examined. Results suggest that each drug tends to provide: 1) unique sexual effects, 2) its own form of disinhibition, and 3) atypical sexual choices, often described as "lower sexual standards." Differences across drugs emerged with regard to social, sensual and sexual enhancement, sexual interest, and impotence. Although some common perceived sexual effects exist across drugs, the wide variation in these effects suggests different levels of risk and may further suggest varying motivations for using each substance. This study seeks to educate public health officials regarding the sexual effects of club drug use in this population.

Substance use in lesbian, gay, and bisexual populations: an update on empirical research and implications for treatment

Historically, substance use problems were thought to be more prevalent in lesbian, gay, and bisexual (LGB) populations, and correcting skewed perceptions about substance abuse among LGB individuals is critically important. This review provides an update on empirical evidence on LGB substance use patterns and treatment outcome, with specific focus on clinical implications of findings. Compared to earlier studies, the recent research included in this review has used more sophisticated methodologies and more representative samples, and also has investigated multiple dimensions of sexual orientation in relation to substance use patterns. Findings from recent research suggest that lesbians and bisexual women are at greater risk for alcohol and drug use disorders and related problems, and that gay and bisexual men are at greater risk for illicit drug use and related problems. Several sociocultural factors have emerged as correlates of substance use patterns in LGB populations (e.g., affiliation with gay culture, HIV status), and several demographic characteristics (e.g., female, older age) do not appear to be as robust of protective factors against substance abuse for LGB individuals compared to heterosexual populations. Bisexual identity and/or behavior in particular seem to be related to increased risk for substance abuse. In terms of treatment outcome, limitations of extant research prevent conclusions about the relative impact of LGB-specific interventions, and further research that includes women and uses more equivalent comparison interventions is needed. Clinical implications of research findings are discussed for case identification, selection of treatment goals (e.g., moderation vs. abstinence), targets for intervention, and specific treatment modalities.

"High on my own supply": correlates of drug dealing among heterosexually identified methamphetamine users

Although rates of methamphetamine use continue to increase throughout the United States, little is known about the individuals who sell methamphetamine at the street level. This exploratory study examined the prevalence and correlates of drug-dealing behavior in a sample of 404 heterosexually identified methamphetamine users who were participants in a sexual risk reduction intervention in San Diego, California. Twenty-nine percent of participants (N = 116) reported "dealing" methamphetamine in the past 2 months. In a multivariate logistic regression, methamphetamine dealing was associated with being male (OR = 1.99; 95% CI 1.16-3.39), younger age (OR = 1.87 per year; 95% CI 1.10-3.17), more frequent use of methamphetamine (OR = 2.69; 95% CI 1.59-4.57), injecting methamphetamine (OR = 3.10; 95% CI 1.79-5.37), and higher hostility scores (OR = 1.07 per unit increase; 95% CI 1.01-1.13). These characteristics, particularly intensity of drug use and hostility, may be associated with greater resistance to drug treatment and lower success in treatment programs.
