Abstract
Correlational evidence has linked methamphetamine use and HIV sexual risk behavior, but the direct effects of methamphetamine on sexual desire and sexual decision making in humans have not been tested. This study was designed to test the effect of methamphetamine administration on sexual desire and hypothetical condom-use decisions as measured by the Sexual Delay Discounting Task. Recreational stimulant users (n = 19) participated in this within-subject, placebo-controlled study comparing the effects of 0 mg, 20 mg, and 40 mg of oral methamphetamine. Compared to placebo, methamphetamine caused dose-related and time-related increases in a single-item sexual desire rating and some standard stimulant abuse liability ratings, as well as dose-related increases in the Sexual Arousal and Desire Inventory (SADI; a multidimensional scale capturing positive and negative aspects of desire/arousal). However, methamphetamine caused no significant mean differences in likelihood of condom use within the Sexual Delay Discounting Task or the Monetary Discounting Task. SADI scores were negatively correlated with change from placebo in condom use likelihood in the Sexual Delay Discounting Task for some partner conditions (i.e., decreased reported likelihood of condom use in participants who experienced increased desire/arousal and vice versa). These mixed results may be consistent with methamphetamine's role as both a treatment for attention-deficit/hyperactivity disorder and as a drug of abuse associated with increased delay discounting, and they suggest that methamphetamine's effects on discounting may be modulated by the reinforcing properties of what is being discounted. Delay discounting may be an understudied element of risky sexual decision making, particularly among individuals who use methamphetamine. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Abstract
We analysed the impact of recreational drug use (RDU) on different outcomes in people living with HIV (PLHIV). A multicentre retrospective cohort study was performed with two cohorts of PLHIV included: people using recreational drugs (PURD) vs. people not using recreational drugs (PNURD). Overall, 275 PLHIV were included. RDU was associated with men having sex with men (OR 4.14, 95% CI [1.14, 5.19]), previous sexually transmitted infections (OR 4.00, 95% CI [1.97, 8.13]), and current smoking (OR 2.74, 95% CI [1.44, 5.19]). While the CD4/CD8 ratio increased amongst PNURD during the follow-up year, it decreased amongst PURD (p = 0.050). PURD presented lower scores of self-reported and multi-interval antiretroviral adherence (p = 0.017, and p = 0.006, respectively), emotional well-being (p < 0.0001), and regular follow-up (p = 0.059), but paid more visits to the emergency unit (p = 0.046). RDU worsens clinical, immunological, and mental health outcomes amongst PLHIV.

Characteristics and Longitudinal Patterns of Erectile Dysfunction Drug Use Among Men Who Have Sex with Men in the U.S. ARCHIVES OF SEXUAL BEHAVIOR 2021; 50:2887-2896. [PMID: 34590217 PMCID: PMC8563532 DOI: 10.1007/s10508-021-02065-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 04/26/2021] [Accepted: 06/02/2021] [Indexed: 06/02/2023]
Abstract
We investigated the longitudinal relationship between erectile dysfunction (ED) drug use with behavioral factors, including substance use and sexual activities in men who have sex with men from the Multicenter AIDS Cohort Study during 1998-2016 (n = 1636). We used a bivariate random-intercept model to evaluate ED drug use along with other behavioral factors to assess relationships between the two outcomes over time on a population level and also at the individual level. Average ED drug use among men who have sex with men (MSM) with HIV was positively correlated with average use of marijuana (r = .19), poppers (r = .27), and stimulants (r = .25). In this group, testosterone use (r = .32), multiple partners (r = .41), insertive anal intercourse with condom (r = .40), and insertive anal intercourse without condom (r = .43) all showed moderate correlations over time with average ED use (p < .001). Associations among MSM without HIV were similar, with average marijuana use (r = .19) and stimulant use (r = .22) being positively correlated with average ED drug use, and were also correlated with having multiple partners (r = .36), insertive anal intercourse with condom (r = .22), and insertive anal intercourse without condom (r = .18) over time. Positive within-individual associations between ED drug use and multiple partners and insertive anal intercourse with and without condom were observed regardless of HIV serostatus. This study showed that MSM who reported use of ED drugs were also, on average, more likely to use recreational drugs and engage in sexual activities, such as having multiple partners and insertive anal intercourse. Within individuals, average ED drug use was also positively correlated with sexual behaviors.

Abstract
Background: The prevalence of chemsex and sexualized substance use is increasing in several European countries, particularly among men who have sex with men. In this subgroup, illegal substance use is associated with increased sexual risk behavior, which can result in severe physical and psychological impairments. The present study examined the incidence and prevalence of chemsex in German-speaking countries. Methods: To further describe the high-risk group of Chemsex users, participants (N = 429) were asked about their psychotropic substance use, sexual and health-related behavior, health status, and socio-demographic information by using an online questionnaire. Whether Chemsex has negative effects on well-being was measured with the WHO well-being index. Of additional interest was how informed Chemsex users are about the topic and what needs are placed on the practitioners. The online questionnaire consisted of 105 items, and data was collected from March to May 2019. Thousand forty seven datasets were saved with a dropout rate of 59%, 123 completed questionnaires fulfilled the criteria for chemsex users (n =123). Results: There were no significant differences in well-being between chemsex users and non-users. All participants protected themselves against sexually transmitted diseases irregularly or not at all. The majority of chemsex users reported intermittently using illegal substances (ketamine, methamphetamine, mephedrone, γ-butyrolactone/γ-hydroxy butyric acid). They viewed their sexual and substance use behavior as problematic, but few showed motivation for behavior change. Chemsex users clearly expressed a need for more information and advice centers. Conclusion: The results provide information on chemsex users that can be used for the future development of a therapy manual and thus contribute to improving health care for this group. The prevalence of chemsex is increasing and urgently needs more research to protect clients from health impairments and stigmatization.

Abstract
BACKGROUND Antiretroviral therapy (ART) non-adherence and methamphetamine use are associated with higher HIV drug resistance prevalence. How they affect drug resistance mutations accumulation is less studied. OBJECTIVE We assessed factors associated with drug resistance mutations accumulation. METHODS We evaluated HIV chronically-infected patients from a clinic-based research cohort on first-line ART regimens with genotype results within 30 days of baseline. Methamphetamine use and ART adherence were self-reported at each study visit. High ART adherence was defined as 0-5% missed doses in the last 30 days. RESULTS One-hundred twenty-five patients contributed 496 study visits. At baseline, 81% of patients reported high ART adherence; 90% reported no methamphetamine use in the prior 4 months, 8% used monthly or less and 2% used daily or weekly. Methamphetamine users and non-users had similarly high ART adherence (p=0.93). Adjusted incidence rate ratio (aIRR) of drug resistance mutations accumulation was 2.04 (95% CI 0.64, 6.46) for daily/weekly users and 1.71 (95% CI 0.66, 4.42) for patients with monthly or less users, compared to non-users. aIRR was 0.71 (95% CI 0.44, 1.15) with >5-10% missed ART doses and 1.21 (95% CI 0.80, 1.83) with >10% missed doses compared to 0-5% missed doses. CONCLUSION We found no strong evidence for the effect of methamphetamine use and ART adherence on drug resistance mutations accumulation. Research cohort patients may have been more engaged in care and treatment adherent than non-cohort patients. Our findings suggest methamphetamine use might not lead to treatment failure among HIV patients who are otherwise engaged in care.

Abstract
The age of patients living with human immunodeficiency virus (HIV) is increasing and the greatest proportion of aged HIV patients occurred in Western and Central Europe and North America (WCENA). In aged HIV patients in WCENA, older MSM is the main population. The aim of our study was to evaluate the HIV prevalence in older MSM in WCENA. A meta-analysis was conducted. We searched Medline, Embase, PsycINFO, Web of Science, Cochrane library, Ageline databases, and government websites. Studies that estimated HIV prevalence in older MSM in WCENA were selected. The pooled HIV prevalence and odds ratio (OR) of the risk of living with HIV in older MSM were calculated. In total of 23000 records were initially records were identified and 12 records were included. The total sample size of older MSM was 6118. The pooled HIV prevalence in older MSM in WCENA was 26% (95% CI 18%-33%), which was much higher than that in younger MSM (18%, 95% CI 14%-21%). Notably, the HIV prevalence in older MSM has been continuously increasing in the past two decades in WCENA, raising from 16% to 33%. The pooled OR for older MSM to be living with HIV was 1.68 compared to younger MSM. The HIV prevalence in older MSM in WCENA is disproportionately high, with a continuously increasing trend in the past two decades. Older MSM also carry significantly higher risk of living with HIV than younger MSM.

Abstract
Sexual risk behaviors among men who have sex with men (MSM) have been linked to diverse demographic, psychosocial, and behavioral factors. This study assessed the association between internalized homophobia and sexual risk behavior among HIV-infected MSM and the mediating effects of safe-sex self-efficacy and depression on this association, using a theoretical framework based on the Theory of Social Action. Data were collected from 124 HIV-infected MSM attending an AIDS clinic in Israel. No significant association was found between internalized homophobia and sexual risk behavior (unprotected anal intercourse). Examination of mediation effects revealed full mediation by depression, but not by self-efficacy. Depression and self-efficacy were the only significant explanatory variables of sexual risk behavior. Diverse social work interventions with HIV-infected MSM aimed at reducing sexual risk behaviors should include routine screening of IH and its association with depression, and address depression and self-efficacy in CBT and other interventions.

Abstract
Background Illicit drug use among men who have sex with men (MSM) has been associated with sexual risk and HIV. Less is documented about associations with other sexually transmissible infections (STIs). The aim of the present study was to determine whether the use of drugs commonly associated with chemsex is associated with increased risk of gonorrhoea among MSM. METHODS Using data from 16065 UK-based respondents to the European MSM Internet Survey (2010), we examined associations between a recent diagnosis of gonorrhoea and three chemsex drugs (crystal methamphetamine, γ-hydroxybutyric acid (GHB)/γ-butyrolactone (GBL) and mephedrone). Univariate logistic regression identified determinants of gonorrhoea diagnosis and multivariate logistic regression models calculated adjusted odds ratios (aORs) for independent associations between chemsex drugs and gonorrhoea. RESULTS MSM who reported using crystal methamphetamine and GHB/GBL in the previous year had 1.92- and 2.23-fold higher odds of gonorrhoea respectively over the same period (P=0.0001 and P<0.0001; n=15137) after adjusting for age, recruitment website, HIV status, residence and use of other chemsex drugs. MSM reporting the use of all three chemsex drugs had the highest increased odds (aOR 3.58; P<0.0001; n=15174). Mephedrone alone was not associated with gonorrhoea in multivariate models. CONCLUSIONS Use of chemsex drugs is associated with a higher risk of gonorrhoea. The results of this study complement existing research about crystal methamphetamine and indicate a role for GHB/GBL in adverse sexual health outcomes. The use of mephedrone alongside other chemsex drugs may account for its lack of association with gonorrhoea in multivariate models. Future research should use encounter-level data, examine other STIs and attribute pathways through which chemsex leads to infection.

Abstract
Amphetamine use is higher among men who have sex with men (MSM) compared with other men, and is associated with sexual behavior linked to HIV transmission. No national estimates of amphetamine use among MSM with HIV have been published. We used data from the Medical Monitoring Project, a nationally representative sample of persons with diagnosed HIV, to describe patterns in amphetamine use in the past 12 months among MSM during 2015-2016 (N = 3796). Prevalence of amphetamine use in this population was 9.6% (95% CI 7.6, 11.6%) in the past 12 months. MSM who used amphetamines were more likely to have condomless sex with partners without HIV or of unknown serostatus (PR 1.87; 95% CI 1.62, 2.16) and less likely to be durably virally suppressed (PR 0.81; 95% CI 0.71, 0.91). Interventions to address amphetamine use and associated transmission risk behaviors among MSM living with HIV may decrease transmission.

Abstract
Risk compensation in an HIV Treatment as Prevention (TasP) environment may increase high-risk sexual and substance use behaviors among people living with HIV. Objective: To examine recent crystal methamphetamine (CM) use/initiation in a longitudinal cohort of gay, bisexual, and other men who have sex with men (GBMSM) living with HIV in Metro Vancouver, Canada. Methods: Eligible participants were GBMSM aged >15 years who reported sex with another man in the past six months. Participants were recruited using respondent-driven sampling and self-completed a computer questionnaire every six months. We used multi-level generalized mixed-effect models to evaluate trends in recent CM use (past six months), multivariable logistic regression to identify covariates of recent CM use, and multivariable survival analysis to identify predictors of CM initiation. Results: Of 207 GBMSM living with HIV at enrollment, 44.3% reported recent CM use; there was a statistically non-significant decrease over the study period (41% in first period to 25% in final period, p = 0.087). HIV treatment optimism was not associated with CM use/initiation. CM use was positively associated with depressive symptomology, sexual escape motivation, transactional sex, number of anal sex partners, condomless anal sex with seroconcordant partners, STIs, and other substance use. Recent CM use was negatively associated with viral load sorting. CM initiation was predicted by escape motivation, transactional sex, and group sex participation. Conclusion: Results suggest that CM use among GBMSM living with HIV is prevalent and increased CM use/initiation is not a consequence of TasP public policy.

Abstract
Background: Methamphetamine (MA) use among gay, bisexual, and other men who have sex with men (gbMSM) is a pervasive issue, associated with detrimental health outcomes. We identified factors associated with discontinuation or reduction in MA among a subset of gbMSM reporting frequent (at least weekly) use, with a specific focus on symptoms of anxiety and depression. Methods: We recruited sexually-active gbMSM aged ≥16 years in Vancouver, Canada into a prospective-cohort study using respondent-driven sampling. Participants completed study visits once every six months. We used generalized linear mixed models to identify factors associated with reductions in MA use following a visit where participants previously reported using MA at least weekly. Results: Of 584 cohort participants with at least one follow-up visit, 67 (11.5%) reported frequent MA use at baseline or in follow-up visits. Of these, 46 (68.7%) had at least one subsequent study visit where they transitioned to less frequent (monthly or less) or no MA use. In multivariable models, reduced MA use was less likely for those who spent >50% of social time with other gbMSM (aRR = 0.49, 95%CI:0.28-0.85), gave or received drugs in exchange for sex (aRR = 0.34, 95%CI:0.13-0.87), injected drugs (aRR = 0.35, 95%CI:0.18-0.68), or used gamma-hydroxybutyrate (GHB) (aRR = 0.41, 95%CI:0.21-0.78). Symptoms of anxiety or depression were not associated with reductions in MA use. Conclusions: Social connection and drug-related factors surrounding MA use were associated with reductions, but anxiety and depressive symptomatology were not. Incorporating socialization and polysubstance-related components with MA reduction may help in developing efficacious interventions toward reducing MA use for gbMSM.

Abstract
Gay, bisexual, and other men who have sex with men (GBMSM) in the United States remain heavily impacted by HIV. The purpose of this study was to describe intergenerational differences in functional knowledge of HIV prevention strategies, perceived risk, recent condomless anal sex (CAS), and HIV testing behavior. Eight hundred sexually active GBMSM were recruited via Facebook from August to September 2015, and administered a Web-based survey which included 12 multiple-choice questions to elicit data regarding functional knowledge of different HIV prevention approaches (e.g., condom use, pre-exposure prophylaxis post-exposure prophylaxis, treatment as prevention, circumcision). Cumulative logit and multivariable logistic models were formulated to examine birth cohort variations across four analytic outcomes. Younger generations were significantly more knowledgeable, as were GBMSM with higher education. Non-Hispanic non-White GBMSM and those reporting a bisexual/other sexual orientation had lower functional knowledge. Younger generations were equally concerned about contracting HIV as their older counterparts. Perceived risk was significantly higher among non-Hispanic non-White and Hispanic GBMSM, but lower among those with higher education and those in a relationship. Finally, birth cohort variations with respect to engaging in CAS with ≥2 men in the past 3 months and testing for HIV in the past year were not markedly pronounced. Younger GBMSM might be more knowledgeable about HIV prevention strategies compared to their predecessors, but are equally concerned about contracting HIV. Researchers and practitioners should consider intergenerational and other demographic differences while designing multifaceted HIV prevention programs for GBMSM.

Abstract
Objectives: Evaluate the demographic data, etiology, operative findings and results of surgical treatment of penile fracture (PF) in men who have sex with men(MSM) with emphasis on sexual complications. Materials and Methods: We studied 216 patients underwent surgical correction of PF at our hospital. Patients self-identified as MSM were followed for at least 6 months. Demographic data, presentation, operative findings, International Index of Erection Function - 5 (IIEF-5) and the Premature Ejaculation Diagnostic Tool. Results: Of 216 PF cases, 4 (1.8%) were MSM. All cases resulted from sexual activity and all patients reported using the “doggy style” position during anal intercourse. Unilateral or bilateral injury of corpus cavernosum was found in 2 patients each. One (25%) patient had complete urethral injury associated with bilateral corpus cavernosum lesion. During the follow-up period, all patients developed some type of sexual complication. One patient reported penile pain during intercourse. Another patient experienced low sexual desire and premature ejaculation. This patient was also dissatisfied with the aesthetic result of the surgical scar and complained about decreased penis size after surgery. The third case developed delayed ejaculation. The fourth patient experienced mild to moderate erectile dysfunction. This same patient presented with penile curvature. Finally, palpable fibrotic nodules in the operative area were observed in all cases. Conclusions: Sexual activity in the “doggy style” position was the commonest cause of PF in MSM. Sexual dysfunction is always present in gay man after surgery for PF. However, additional studies with larger samples should be coinducted.

Abstract
This study sought to determine why young men who have sex with men (MSM) have higher HIV incidence rates than older MSM in the United States. We developed hypotheses that may explain this disparity. Data came from peer-reviewed studies published during 1996-2016. We compared young and older MSM with respect to behavioral, clinical, psychosocial, and structural factors that promote HIV vulnerability. Compared with older MSM, young MSM were more likely to have HIV-discordant condomless receptive intercourse. Young MSM also were more likely to have "any" sexually transmitted infection and gonorrhea. Among HIV-positive MSM, young MSM were less likely to be virally suppressed, use antiretroviral therapy, and be aware of their infection. Moreover, young MSM were more likely than older MSM to experience depression, polysubstance use, low income, decreased health care access, and early ages of sexual expression. These factors likely converge to exacerbate age-associated HIV incidence disparities among MSM.

Individual-level characteristics associated with oral HIV test acceptability among Peruvian men who have sex with men and transgender women: a cross-sectional study.

Abstract
OBJECTIVES Peruvian men who have sex with men (MSM) and transgender women (TGW) are highly vulnerable to HIV infection (HIV), but stigma, access issues and fear of venipuncture hamper testing. The oral HIV test-which uses oral fluids and provides results in 20 minutes-could reduce these barriers. The objective of this study was to determine the acceptability of the oral HIV test and the individual-level factors associated with its acceptability among MSM and TGW. METHODS We conducted a cross-sectional secondary analysis among Peruvian MSM and TGW attending a community-based health centre between February 2012 and February 2013 to determine the individual-level factors associated with oral HIV test acceptability. RESULTS Of 334 participants, 88% were MSM and 12% TGW. Overall, 85% of participants indicated their acceptability of the oral HIV test. Acceptability was higher in MSM than TGW (85.7% vs 80.0%) but this difference was not significant. Factors associated with acceptability in MSM were: tertiary or higher education (prevalence ratio (PR)=1.18, 95% CI 1.06 to 1.32 and PR=1.16, 95% CI 1.03 to 1.30, respectively); sex with drug use (PR=1.19, 95% CI 1.05 to 1.36); believing that HIV is transmitted by saliva (PR=1.20, 95% CI 1.08 to 1.33); and potential use of the oral test at home (PR=1.56, 95% CI 1.32 to 1.85). The only factor associated with lower acceptability was having had first anal intercourse between 14 and 19 years of age (PR=0.89, 95% CI 0.80 to 0.98). CONCLUSIONS We identified the individual factors associated with oral HIV test acceptability among Peruvian MSM and TGW. Expanded use of the oral HIV test to increase testing rates among Peruvian MSM and TGW is recommended. TRIAL REGISTRATION NUMBER NCT01387412, post-results.

Abstract
The number of HIV cases attributed to heterosexual contact and the proportion of women among HIV positive individuals has increased worldwide. Russia is a country with the highest rates of newly diagnosed HIV infections in the region, and the infection spreads beyond traditional risk groups. While young women are affected disproportionately, knowledge of HIV risk behaviors in women in the general population remains limited. The objectives of this study were to identify patterns of behaviors that place women of childbearing age at high risk for HIV transmission and determine whether socio-demographic characteristics and alcohol use are predictive of the risk pattern. A total of 708 non-pregnant women, aged between 18 and 44 years, who were at risk for an alcohol-exposed pregnancy were enrolled in two regions in Russia. Participants completed a structured interview focused on HIV risk behaviors, including risky sexual behavior and alcohol and drug use. Latent class analysis was utilized to examine associations between HIV risk and other demographic and alcohol use characteristics and to identify patterns of risk among women. Three classes were identified. 34.93% of participants were at high risk, combining their risk behaviors, e.g., having multiple sexual partners, with high partner's risk associated with partner's drug use (class I). Despite reporting self-perceived risk for HIV/STI, this class of participants was unlikely to utilize adequate protection (i.e., condom use). The second high risk class included 13.19% of participants who combined their risky sexual behaviors, i.e., multiple sexual partners and having STDs, with partner's risk that included partner's imprisonment and partner's sex with other women (class II). Participants in this class were likely to utilize protection/condoms. Finally, 51.88% of participants were at lower risk, which was associated primarily with their partners' risk, and these participants utilized protection (class III). The odds of being in class I compared with class III were 3.3 (95% CI [1.06, 10.38]) times higher for those women who had Alcohol Use Disorders Identification Test scores ≥ 8 than those who had lower scores, and were 3.9 (95% CI [1.69, 8.97]) times higher for those who used alcohol before sex than those who did not. In addition, women who drank more days per week were 1.36 times more likely to be in class II than in class III. The study informs prevention by identifying specific population groups and targets for interventions. Alcohol use is a significant predictor and an overarching factor of HIV risk in women. Since at-risk drinking is common among young Russian women, alcohol risk reduction should be an essential component of HIV prevention efforts.

Abstract
Early initiation of antiretroviral therapy (ART) reduces the risk of drug-sensitive HIV transmission but may increase the transmission of drug-resistant HIV. We used a mathematical model to estimate the long-term population-level benefits of ART and determine the scenarios under which earlier ART (treatment at 1 year post-infection, on average) could decrease simultaneously both total and drug-resistant HIV incidence (new infections). We constructed an infection-age-structured mathematical model that tracked the transmission rates over the course of infection and modelled the patients' life expectancy as a function of ART initiation timing. We fitted this model to the annual AIDS incidence and death data directly, and to resistance data and demographic data indirectly among men who have sex with men (MSM) in San Francisco. Using counterfactual scenarios, we assessed the impact on total and drug-resistant HIV incidence of ART initiation timing, frequency of acquired drug resistance, and second-line drug effectiveness (defined as the combination of resistance monitoring, biomedical drug efficacy and adherence). Earlier ART initiation could decrease the number of both total and drug-resistant HIV incidence when second-line drug effectiveness is sufficiently high (greater than 80%), but increase the proportion of new infections that are drug resistant. Thus, resistance may paradoxically appear to be increasing while actually decreasing.

Abstract
BACKGROUND Despite rapid increases in crystal methamphetamine (CM) use worldwide and established gendered patterns of use, empirical research on CM injection initiation among sex workers is limited. Given the wide range of harms associated with CM, alongside stimulant effects including sexual dis-inhibition and prolonged awake-ness, this study aimed to longitudinally investigate socio-structural predictors of initiating CM injection among sex workers in Vancouver, Canada. METHODS Data (2010-2014) were drawn from a community-based cohort of women sex workers: AESHA (An Evaluation of Sex Workers Health Access). Participants completed bi-annual interviewer-administered questionnaires and HIV/STI testing. Kaplan Meier methods and Cox proportional hazards regression were used to model predictors of CM injection initiation among CM injection-naïve participants. RESULTS Of 455 participants eligible at baseline, 14.3% (n=65) injected CM for the first time over follow-up, with an incidence density of 6.79 per 100 person-years (95% Confidence Interval [CI] 5.30-8.69). In multivariable analysis, injection heroin use (Adjusted Hazard Ratio [AHR] 6.11; 95%CI 3.24-11.52), having an intimate partner who injects drugs (AHR 2.93; 95%CI 1.57-5.46), workplace violence (AHR 2.85; 95%CI 1.74-4.67), HIV seropositivity (AHR 2.69; 95%CI 1.45-5.00), and childhood abuse (AHR 1.86; 95%CI 0.99-3.49) were independently associated with initiating CM injection. CONCLUSIONS Findings underscore the gendered and social risk environment of CM injection initiation among sex workers. The strong influences of historical/workplace violence, coupled with heroin injection (known to be self-medicating for post-traumatic stress) as a primary risk pathway, emphasize the urgency of increasing access to integrated, trauma-informed addiction treatment and HIV care for marginalized women.

Abstract
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.

Abstract
From February 2010 through December 2014, 585 substance-using MSM were enrolled into a "homegrown" risk reduction intervention. Participants evidenced significant iterative factor reductions in the odds of substance use including alcohol (AOR=0.79) and marijuana (AOR=0.78; both p≤0.05) and marginally significant reductions in the odds of methamphetamine use (AOR=0.83; p≤0.07). Participants also evidenced significant reductions in sexual risks including the odds of reporting drug/alcohol use before or during sex (AOR=0.80) and of condomless anal intercourse (AOR=0.72; all significant at p≤0.05). Results demonstrate that the homegrown intervention was effective at reducing HIV risk behaviors among high-risk MSM.

Abstract
Background Men who have sex with men (MSM) are a risk group for new HIV infections. Drug use among men who have sex with men is often accompanied by risky sexual behaviours. Local AIDS help centres and gay advice centres are recording an increase in drug use among MSM clients in Germany. This study examines reasons for drug use and drug use contexts for MSM, including syndemic factors and experiences of social support. Methods The study is based on a qualitative research approach. We conducted 14 structured, in-depth interviews with substance-using MSM in three German cities. An interview guidance document was used that was developed on the basis of the syndemic approach. Data analysis was based on structured analysis of content. Results The MSM interviewed had extensive experience of drug use, in particular amyl nitrate, amphetamines, methamphetamine, ketamine, cocaine and cannabis. The drugs were used both at parties and in connection with sexual experiences (chemsex). Twelve men said that they had an existing HIV infection at the time of the interview. The men also reported experiences of violence and discrimination because of their sexual orientation. The social networks of the MSM and dating apps are highly relevant for experiencing chemsex. Certain places in the MSM community also have an impact on drug purchase, drug consumption and chemsex sessions. Conclusions MSM are a group that is vulnerable to psychological problems, in particular problematic drug use. This group requires specific help from drug services and AIDS support services that are orientated towards the life situation and substance use contexts of the clients. Both support systems should work together more closely and network. Furthermore, specific prevention strategies, aimed at both mental and physical well-being, should be developed for substance-using MSM.

Illicit drug use and its association with sexual risk behaviour among MSM: more questions than answers? Curr Opin Infect Dis 2016; 29:58-63.

Abstract
PURPOSE OF REVIEW Illicit drug use before or during sex - known as sexualized drug use (colloquially 'chemsex' or 'party and play') - has evolved as novel psychoactive substances have entered the market in many parts of the world. Here, we review key conceptual issues in associations between illicit drug use and sexual risk-behaviour in MSM. RECENT FINDINGS Although many studies have confirmed that MSM use drugs with greater prevalence than the general population, evidence is of variable quality and a sampling frame is difficult to establish. Moreover, psychosocial hypotheses linking drug use and sexual risk, including cognitive escape and sensation seeking, are unsatisfactory and generally ignore strategic use of drugs for sexual aims. Person-level associations between drug use history and both sexual risk behaviour and HIV infection tend to be consistent around the world, but evidence comparing encounters within subjects is generally unclear and out of date. SUMMARY There is a need for interventions for harm reduction targeted at MSM that account specifically for the social and cultural contexts of sexualized drug use. Expanded attention to surveillance of emerging drug use trends can help clinicians in sexual health and infectious diseases best anticipate the needs of their service users.

Abstract
Geosocial networking phone applications (GSN apps) used to meet sexual partners have become popular in the men who have sex with men (MSM) communities of the USA since 2009. Previous studies have shown greater incidence of gonorrhea and chlamydia and lower testing frequency for HIV testing among GSN app users when compared to non-users. The present study aims to determine the type, number, and frequency of apps used, as well as the association between dispositional self-control and health-related behaviors. Participants (n = 146) were recruited from Amazon's Mechanical Turk program to respond to a brief GSN app marketing survey. Multivariate regression was used to determine differences in app priorities, length of app use, and number of sexual partners between high self-control and low self-control participants. A majority of the participants reported using Grindr (78 %) followed by Scruff (19 %), Growlr (12 %), and Jack'd (12 %). Most individuals used one app only (58 %), but a significant proportion reported using two apps (28 %) or three or more apps (14 %). Respondents with low self-control were more likely to report a higher number of hours using GSN apps and a higher number of sexual partners, controlling for race/ethnicity, education, employment, and HIV status. Given the popularity of this burgeoning communication medium, these findings have important implications for developing prevention resources for different segments of GSN app users.

Abstract
Social, relational and network determinants of condom use and HIV testing were examined among 213 men who have sex with men (MSM) in Beirut. 64% reported unprotected anal intercourse (UAI), including 23% who had UAI with unknown HIV status partners (UAIU); 62% had HIV-tested. In multivariate analysis, being in a relationship was associated with UAI and HIV testing; lower condom self-efficacy was associated with UAIU and HIV testing; gay discrimination was associated with UAIU; MSM disclosure was associated with UAI, UAIU and HIV testing; and network centralization was associated with HIV testing. Multi-level social factors influence sexual health in MSM.

Abstract
The objectives of this study were to identify risk factors associated with acute and early HIV infection (AEH) among men who have sex with men (MSM) undergoing community HIV testing and to compare demographics in those diagnosed with AEH with those diagnosed at chronic stage of HIV infection.In this retrospective cohort study, we analyzed risk factors associated with AEH among 8925 unique MSM (including 200 with AEH [2.2%] and 219 [2.5%] with newly diagnosed chronic HIV infection) undergoing community-based, confidential AEH screening in San Diego, California.The combination of condomless receptive anal intercourse (CRAI) plus ≥5 male partners, CRAI with an HIV-positive male, CRAI with a person who injects drugs, and prior syphilis diagnosis were significant predictors of AEH in the multivariable Cox regression model. Individuals reporting ≥1 of these 4 risk factors had a hazard ratio of 4.6 for AEH. MSM diagnosed with AEH differed in race (P = 0.005; more reported white race [P = 0.001], less black race [P = 0.030], trend toward less Native American race [P = 0.061]), when compared to those diagnosed with chronic HIV infection, while there was no difference observed regarding age.We established a multivariate model for the predicting risk of AEH infection in a cohort of MSM undergoing community HIV screening, which could be potentially used to discern those in need of further HIV nucleic acid amplification testing for community screening programs that do not test routinely for AEH. In addition, we found that race differed between those diagnosed with AEH and those diagnosed at chronic stage of HIV infection underlining the need for interventions that reduce stigma and promote the uptake of HIV testing for black MSM.

Abstract
PURPOSE Men who have sex with men (MSM) continue to be overrepresented in rates of incidence and prevalence of human immunodeficiency virus (HIV). Both HIV-diagnosed (HIV-D) and HIV-nondiagnosed (HIV-N) MSM report a variety of reasons for intentional and unintentional nonuse of condoms. Elucidating and comparing reasons for continued engagement in condomless anal sex specific to both HIV-D and HIV-N MSM likely is important to identifying effective prevention. METHODS This study employed meta-analytic methods to evaluate and compare correlates to condomless anal sex in both HIV-D and HIV-N MSM from primary studies from 1993 to February 2013. RESULTS Of the 19 individual correlates assessed within the subgroup of HIV-D MSM, variables that achieved significant effect were alcohol, mind-altering substance use, sexual-enhancement medication, intentional condom nonuse, self-efficacy, attitudes toward condom use, social support, gay identity, compulsivity, trading sex, and number of sex partners. Those that were statistically non-significant were intention to use a condom, perceived risk, perceived norms, perceived responsibility, HIV medical management, treatment optimism, mental health, and setting. Of the 12 correlates assessed within the subgroup of HIV-N MSM, variables that achieved significant effect were alcohol, mind-altering substance use, intentional condom nonuse, attitudes toward condom use, perceived risk, and setting. Those observed as statistically non-significant were perceived norms, social support, gay identity, mental health, trading sex, and number of sex partners. CONCLUSION Study results have clinical implications that may guide future prevention research and practice by highlighting risk variables shared between HIV-N and HIV-D MSM, as well as variables observed to be unique to each group that may warrant more tailored intervention. Further investigation is recommended to elucidate the relationships among these variables such that optimal intervention can be determined.

Abstract
Fifty-two non-treatment-seeking methamphetamine-using men who have sex with men were enrolled in Project Tech Support, an open-label pilot study to evaluate whether exposure to theory-based [social support theory (SST), social cognitive theory (SCT), and health belief model (HBM)] text messages could promote reductions in HIV sexual risk behaviors and/or methamphetamine use. Multivariable analyses revealed that increased relative exposure to HBM or SCT (vs. SST) text messages was associated with significant reductions in the number of HIV serodiscordant unprotected (i.e., without a condom) anal sex partners, engagement in sex for money and/or drugs, and frequency of recent methamphetamine use; additionally, increased relative exposure to HBM (vs. SCT or SST) messages was uniquely associated with reductions in the overall number of non-primary anal sex partners (all p ≤ 0.05, two-tailed). Pilot data demonstrated that text messages based on the principles of HBM and SCT reduced sentinel HIV risk and drug use behaviors in active methamphetamine users.

Abstract
OBJECTIVE To evaluate current club drug use and its potential association with the transmission of HIV/STD among Changsha men who have sex with men (MSM). METHOD A cross-sectional survey was conducted by using self-administered questionnaires including information regarding socio-demographics, club drug use, high-risk behaviors, and HIV/STD infections. Multiple methods including venue-based, peer referral using "snowball" techniques, and internet advertisements were used to recruit study participants. RESULTS Of the 826 participants, 177 (21.4%) reported that they had used club drugs at some time before or during sex in the past six months. MSM with young age, low education level, and seeking partners through the internet or bars were the main population who used drugs. Poppers were the most common drug used among Changsha MSM. The prevalence of HIV, syphilis, and herpes simplex virus-2 were higher among drug users. There were no significant differences in unprotected sexual intercourse and condom use between drug users and non-users. Compared with non-users, risk behaviors such as group sex, multiple sex partners, and sex with foreigners were more frequent among drug users. CONCLUSION Club drug use is common among Changsha MSM, and is related to unsafe sex activities and HIV/STD infection. It is necessary to build novel targeted HIV prevention strategies to monitor and reduce club drug use among MSM.

Abstract
OBJECTIVES The objectives of this study were to estimate the point prevalence of sexually transmitted infection (STI) and to investigate the sexual practices and behaviours associated with STIs in a group of gay men, other men who have sex with men and transgender women (GMT) in the province of La Romana, Dominican Republic. DESIGN A cross-sectional study of a convenience sample of GMT persons. SETTING The study was conducted in the province of La Romana, Dominican Republic, in June-July 2013. PARTICIPANTS Out of 117 GMT persons screened, a total of 100 completed the study. Participants had to be at least 18 years of age, reside in La Romana and have had sex with another man in the preceding 12 months. All participants were interviewed and tested for STI. PRIMARY OUTCOME MEASURE The main outcome of interest was the detection of any STI (HIV, herpes simplex virus type 2 (HSV-2), syphilis, hepatitis B or C) by serology. RESULTS Among 100 participants, the median age was 22 years (range 18-65). One-third had consumed illicit drugs the preceding year and only 43% consistently used condoms. Prevalence was 38% for HSV-2, 5% for HIV and 13% for syphilis. There were no cases of hepatitis B or C. Factors associated with the odds of a STI were age >22 years (OR=11.1, 95% CI 3.6 to 34.5), receptive anal intercourse (OR=4.2, 95% CI 1.3 to 13.6) and having ≥2 male sexual partners during the preceding month (OR=4, 95% CI 1.3 to 12.5). CONCLUSIONS In this group of GMT persons, seroprevalence of STI was high, and a number of risk behaviours were associated with STI. These preliminary data will help inform policy and programmes to prevent HIV/STI in GMT persons in the region.

Abstract
BACKGROUND Although men who have sex with men (MSM) represent a dominant risk group for human immunodeficiency virus (HIV), the risk of HIV infection within this population is not uniform. The objective of this study was to develop and validate a score to estimate incident HIV infection risk. METHODS Adult MSM who were tested for acute and early HIV (AEH) between 2008 and 2014 were retrospectively randomized 2:1 to a derivation and validation dataset, respectively. Using the derivation dataset, each predictor associated with an AEH outcome in the multivariate prediction model was assigned a point value that corresponded to its odds ratio. The score was validated on the validation dataset using C-statistics. RESULTS Data collected at a single HIV testing encounter from 8326 unique MSM were analyzed, including 200 with AEH (2.4%). Four risk behavior variables were significantly associated with an AEH diagnosis (ie, incident infection) in multivariable analysis and were used to derive the San Diego Early Test (SDET) score: condomless receptive anal intercourse (CRAI) with an HIV-positive MSM (3 points), the combination of CRAI plus ≥5 male partners (3 points), ≥10 male partners (2 points), and diagnosis of bacterial sexually transmitted infection (2 points)-all as reported for the prior 12 months. The C-statistic for this risk score was >0.7 in both data sets. CONCLUSIONS The SDET risk score may help to prioritize resources and target interventions, such as preexposure prophylaxis, to MSM at greatest risk of acquiring HIV infection. The SDET risk score is deployed as a freely available tool at http://sdet.ucsd.edu.

Abstract
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.

Amphetamine-type stimulants and HIV infection among men who have sex with men: implications on HIV research and prevention from a systematic review and meta-analysis. J Int AIDS Soc 2015; 18:19273. [PMID: 25609214 PMCID: PMC4302169 DOI: 10.7448/ias.18.1.19273] [Citation(s) in RCA: 63] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2014] [Revised: 11/02/2014] [Accepted: 11/28/2014] [Indexed: 01/17/2023] Open
Abstract
Introduction HIV infections and the use of amphetamine-type stimulants (ATS) among men who have sex with men (MSM) have been increasing internationally, but the role of ATS use as a co-factor for HIV infection remains unclear. We aimed to summarize the association between ATS use and HIV infection among MSM. Methods We conducted a systematic search of MEDLINE, EMBASE, GLOBAL HEALTH and PsycINFO for relevant English, peer-reviewed articles of quantitative studies published between 1980 and 25 April 2013. Pooled estimates of the association – prevalence rate ratios (PRR, cross-sectional studies), odds ratio (OR, case-control studies) and hazard ratio (HR, longitudinal studies), with 95% Confidence Intervals (CI) – were calculated using random-effects models stratified by study design and ATS group (meth/amphetamines vs. ecstasy). We assessed the existence of publication bias in funnel plots and checked for sources of heterogeneity using meta-regression and subgroup analysis. Results We identified 6710 article titles, screened 1716 abstracts and reviewed 267 full text articles. A total of 35 publications were eligible for data abstraction and meta-analysis, resulting in 56 records of ATS use. Most studies (31/35) were conducted in high-income countries. Published studies used different research designs, samples and measures of ATS use. The pooled association between meth/amphetamine use and HIV infection was statistically significant in all three designs (PRR=1.86; 95% CI: 1.57–2.17; OR=2.73; 95% CI: 2.16–3.46 and HR=3.43; 95% CI: 2.98–3.95, respectively, for cross-sectional, case-control and longitudinal studies). Ecstasy use was not associated with HIV infection in cross-sectional studies (PRR=1.15; 95% CI: 0.88–1.49; OR=3.04; 95% CI: 1.29–7.18 and HR=2.48; 95% CI: 1.42–4.35, respectively, for cross-sectional, case-control and longitudinal studies). Results in cross-sectional studies were highly heterogeneous due to issues with ATS measurement and different sampling frames. Conclusions While meth/amphetamine use was significantly associated with HIV infection among MSM in high-income countries in all study designs, evidence of the role of ecstasy in HIV infection was lacking in cross-sectional studies. Cross-sectional study design, measurement approaches and source populations may also be important modifiers of the strength and the direction of associations. Event-specific measure of individual drug is required to establish temporal relationship between ATS use and HIV infection. HIV prevention programmes targeting MSM should consider including interventions designed to address meth/amphetamine use.

Abstract
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.

Abstract
With few exceptions, much of sexual science builds upon data from opportunistic nonprobability samples of limited generalizability. Although probability-based studies are considered the gold standard in terms of generalizability, they are costly to apply to many of the hard-to-reach populations of interest to sexologists. The present article discusses recent conclusions by sampling experts that have relevance to sexual science that advocates for nonprobability methods. In this regard, we provide an overview of Internet sampling as a useful, cost-efficient, nonprobability sampling method of value to sex researchers conducting modeling work or clinical trials. We also argue that probability-based sampling methods may be more readily applied in sex research with hard-to-reach populations than is typically thought. In this context, we provide three case studies that utilize qualitative and quantitative techniques directed at reducing limitations in applying probability-based sampling to hard-to-reach populations: indigenous Peruvians, African American youth, and urban men who have sex with men (MSM). Recommendations are made with regard to presampling studies, adaptive and disproportionate sampling methods, and strategies that may be utilized in evaluating nonprobability and probability-based sampling methods.

Abstract
OBJECTIVES To characterize migration patterns among people diagnosed as having and who died of acquired immunodeficiency syndrome (AIDS) from 1993 to 2007 because migrating to a new community can disrupt human immunodeficiency virus/AIDS care delivery and patients' adherence to care and affect migrants' social services and healthcare needs. METHODS Florida AIDS surveillance data were used to describe patterns of migration among people diagnosed as having and who died of AIDS from 1993 to 2007. Individual and community characteristics were compared between residence at the time of AIDS diagnosis and residence at the time of death by type of migration. RESULTS Of 31,816 people in the cohort, 2510 (7.9%) migrated to another county in Florida and 1306 (4.1%) migrated to another state. Interstate migrants were more likely to be men, 20 to 39 years old, non-Hispanic white, and born in the United States, to have had a transmission mode of injection drug use (IDU) or men who have sex with men with IDU (MSM&IDU), and to have been diagnosed before 1999. Intercounty migrants were more likely to be non-Hispanic white, younger than 60 years, have had a transmission mode of MSM, IDU, or MSM&IDU, have higher CD4 counts/percentages, and to have lived in areas with low levels of poverty or low physician density. There was a small net movement from urban to rural areas within the state. CONCLUSIONS A sizable percentage of people, particularly younger people and people with a transmission mode of IDU and IDU&MSM, migrated at least once between the time of their AIDS diagnosis and death. This has important implications for care and treatment, as well as efforts to prevent the disease. Further research is needed to explore barriers and facilitators to access to care upon migration and to assess the need for programs to help people transfer their human immunodeficiency virus/AIDS care, ensuring continuity of care and adherence.

Abstract
An outreach program performed street encounters with 5,599 unique substance-using MSM from January 2008 through December 2011. HIV prevalence reduced from 20.2% in the first half of 2008 to 8.1% in the second half of 2011. Older, gay-identified, non-Hispanic/Latino participants were each more likely to report a HIV-positive serostatus. When controlling for these cofactors, robust log-Poisson analysis revealed that each additional day of methamphetamine (RRR = 1.03; 95% CI [1.02, 1.03]) and/or marijuana (RRR = 1.01; 95% CI [1.01, 1.02]) use in the previous 30 days, injection drug use at any point in their lifetime (RRR = 2.01; 95% CI [1.70, 2.37]), and/or unprotected anal intercourse with another male in the previous 30 days (RRR = 1.48; 95% CI [1.29, 1.71]) were associated with HIV-positive status. When controlling for all these cofactors, the probability of reporting a HIV-positive status reduced an estimated 9% (95% CI [6%, 12%]) every six months throughout the reporting period. Self-reported HIV prevalence decreased among this sample of substance-using MSM in LAC from 2008 to 2011.

Abstract
Objectives To examine alcohol and drug use during unprotected anal intercourse (UAI), and whether use is associated with HIV-related risk behaviours among gay and bisexual men in Scotland. Methods Cross-sectional survey of 17 gay commercial venues in Glasgow and Edinburgh in May 2011 (n=1515, 65.2% response rate); 639 men reporting UAI are included. Results 14.4% were always and 63.4% were sometimes drunk during UAI in the previous 12 months; 36.3% always/sometimes used poppers; 22.2% always/sometimes used stimulant or other recreational/illicit drugs; and 14.1% always/sometimes used Viagra. All were significantly correlated and, in multivariate analysis, the adjusted odds of having UAI with 2+ partners in the previous 12 months were significantly higher for men who reported stimulant or recreational/illicit drug use during UAI (AOR=2.75, 95% CI 1.74 to 4.34) and the adjusted odds of UAI with casual partners were higher for men who reported poppers use (AOR=1.50, 95% CI 1.03 to 2.17). Men who reported always being drunk during UAI were more likely to report UAI with 2+ partners (AOR=1.68, 95% CI 1.01 to 2.81), casual partners (AOR=2.18, 95% CI 1.27 to 3.73), and partners of unknown/discordant HIV status (AOR=2.14, 95% CI 1.29 to 3.53), than men who were not. Conclusions Our study suggests alcohol and drug use may be relatively common during UAI among gay and bisexual men in Scotland. Brief alcohol or drug interventions, particularly in clinical settings, are justified, but should be properly evaluated and take into account the potential influence of broader, situational and social factors on sexual risk.

Abstract
Shared methamphetamine injection is an emerging route of drug use among Iranian methamphetamine injectors. It is a primary vector for blood-borne infections. The aim of the current study is to determine the prevalence and correlates of shared methamphetamine injection in a sample of Iranian methamphetamine injecting treatment seekers in the south of Tehran. We surveyed male and female methamphetamine injectors at three drop-in centres and 18 drug-use community treatment programmes. Participants reported socio-demographic characteristics, drug use, high-risk behaviours, current status of viral infections and service use for drug treatment. Bivariate and multivariate logistic regression models were used to test associations between participants' characteristics and shared methamphetamine injection. Overall, 209 clients were recruited; 90.9% were male; 52.6% reported current methamphetamine injection without any shared injection behaviour and 47.4% reported current shared methamphetamine injection. Shared methamphetamine injection was found to be primarily associated with living with sex partners (AOR 1.25, 95% CI 1.13-1.98), reporting ≥3 years of dependence on methamphetamine injection (AOR 1.61, 95% CI 1.27-2.12), injection with pre-filled syringes in the past 12 months (AOR 1.96, 95% CI 1.47-2.42), homosexual sex without condom use in the past 12 months (AOR 1.85, 95% CI 1.21-2.25), the paucity of NA group participation in the past 12 months (AOR 0.67, 95% CI 0.41-0.99), the paucity of attending psychotherapeutic sessions in the past 12 months (AOR 0.44, 95% CI 0.28-0.96) and positive hepatitis C status (AOR 1.98, 95% CI 1.67-2.83). Deeper exploration of the relationship between shared methamphetamine injection and sexual risk among Iranian methamphetamine injectors would benefit HIV/sexually transmitted infection prevention efforts. In addition, existing psychosocial interventions for methamphetamine-injecting population may need to be adapted to better meet the risks of shared methamphetamine injectors.

Engagement in HIV Medical Care and Technology Use among Stimulant-Using and Nonstimulant-Using Men who have Sex with Men. AIDS Res Treat 2013; 2013:121352.

Abstract
Aims of this study were to assess the associations between stimulant use and attitudes toward and engagement in HIV medical care and to examine technology use among stimulant-using and nonstimulant-using men who have sex with men (MSM). HIV-positive MSM (n = 276; mean age = 42 years; 71% white, non-Hispanic; 43% with college degree) completed an online survey in 2009. Most men (69%) had not missed any scheduled HIV medical appointments in the past year, while 23% had missed at least one, and 9% had not attended any appointments. Stimulant use was significantly associated with not attending any HIV medical appointments in the unadjusted model (relative risk ratio (RRR) = 2.84, 95% CI [1.07, 7.58]), as well as in models adjusted for demographic (RRR = 3.16, 95% CI [1.13, 8.84]) and psychosocial (RRR = 3.44, 95% CI [1.17, 10.15]) factors (Ps < 0.05). Fewer stimulant-using than non-stimulant-using men rated HIV medical care a high priority (57% versus 85%; P < 0.01). Few significant differences were found in online social networking or mobile phone use between stimulant-using and non-stimulant-using MSM, even when stratified by engagement in HIV care. Findings indicate that stimulant use is uniquely associated with nonengagement in HIV medical care in this sample, and that it may be possible to reach stimulant-using MSM using online social networking and mobile technologies.

Abstract
Background Expanding access to highly active antiretroviral therapy (HAART) has become an important approach to HIV prevention in recent years. Previous studies suggest that concomitant changes in risk behaviours may either help or hinder programs that use a Treatment as Prevention strategy. Analysis We consider HIV-related risk behaviour as a social contagion in a deterministic compartmental model, which treats risk behaviour and HIV infection as linked processes, where acquiring risk behaviour is a prerequisite for contracting HIV. The equilibrium behaviour of the model is analysed to determine epidemic outcomes under conditions of expanding HAART coverage along with risk behaviours that change with HAART coverage. We determined the potential impact of changes in risk behaviour on the outcomes of Treatment as Prevention strategies. Model results show that HIV incidence and prevalence decline only above threshold levels of HAART coverage, which depends strongly on risk behaviour parameter values. Expanding HAART coverage with simultaneous reduction in risk behaviour act synergistically to accelerate the drop in HIV incidence and prevalence. Above the thresholds, additional HAART coverage is always sufficient to reverse the impact of HAART optimism on incidence and prevalence. Applying the model to an HIV epidemic in Vancouver, Canada, showed no evidence of HAART optimism in that setting. Conclusions Our results suggest that Treatment as Prevention has significant potential for controlling the HIV epidemic once HAART coverage reaches a threshold. Furthermore, expanding HAART coverage combined with interventions targeting risk behaviours amplify the preventive impact, potentially driving the HIV epidemic to elimination.

Abstract
Gay men increasingly use non condom-based risk reduction strategies to reduce the possibility of HIV transmission. Such strategies rely on men's knowledge and communication with each other, but how they employ these strategies may depend as much on their attitudes toward risk and pleasure. We explored current beliefs about safe sex, sexual desire and risk behavior in an online survey of 2306 Australian gay men. The survey included free text components to explore men's beliefs about risk and pleasure. We conducted a principal components factor analysis on the safe sex belief items in the survey, and thematic analysis of the qualitative material was used to interrogate the concepts underpinning these beliefs. We identified two measures of safe sex beliefs: risk reduction optimism (HRRO; α = 0.703); and viral load optimism (α = 0.674). In multivariate analysis, unprotected anal intercourse with casual partners (UAIC) was associated with HRRO among non HIV-positive men only (p < 0.001), but, regardless of HIV serostatus, UAIC was associated with a belief that serosorting could be an effective risk reduction strategy and with being more sexually adventurous in general. Using the qualitative data we identified four themes in how men think about HIV: 'seeking certainty', 'regretful actions', 'nothing is safe', and 'acting on beliefs'. Each theme interacted with the safe sex beliefs measures to provide a highly contextualised understanding of men's beliefs about safe in specific circumstances. Gay men think about the risk of HIV transmission in qualitatively different ways depending on specific circumstances. While measures of belief about relative risk of HIV transmission are useful indicators of men's propensity to take risk, they oversimplify men's thinking about risk, and fail to account for the role of desire, both in influencing men's thinking about risk, and in how they balance their perception of relative risk against the pursuit of pleasure.

Digiusto E, Rawstorne P. Is it really crystal clear that using methamphetamine (or other recreational drugs) causes people to engage in unsafe sex? Sex Health 2013; 10:133-7. [DOI: 10.1071/sh12053] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2012] [Accepted: 10/11/2012] [Indexed: 11/23/2022]
Abstract
Many studies have found associations between unsafe sexual behaviour and use of crystal methamphetamine (and many other recreational drugs). Researchers and authors of relevant articles in popular media have often interpreted these associations as meaning that using ‘crystal’ directly causes people to engage in unsafe sex, and that interventions should aim to reduce crystal use in order to reduce the prevalence of sexually transmissible infections such as HIV. There is consistent evidence that crystal users are a high-risk group in terms of sexual behaviour. However, most relevant studies have provided only circumstantial evidence regarding a causal relationship. Promoting the idea that a particular recreational drug is a major direct cause of unsafe sex may have the unintended adverse effect of creating an excuse for engaging in unsafe sex, thereby increasing its use, and may incur opportunity costs by preventing limited available health promotion resources from being directed more usefully. This paper examines the limitations, in terms of demonstrating causality, of various types of study that have been published on this topic in relation to crystal use in particular. Researchers who investigate relationships between recreational drug use and behaviour, including sexual behaviour, should be careful about the wording of their conclusions and recommendations, and should consider the possibly counterproductive ways in which their findings might be represented in the media.

Abstract
The present investigations applied a theoretical perspective regarding the impact of executive functioning (EF) on sexual risk among substance users, using a methodological approach designed to examine whether EF subtypes differentially predict behavior patterns. Participants included 104 substance-using HIV-negative gay and bisexual men. Participants completed 5 neuropsychological assessment tasks selected to tap discrete EF components, and these data were linked to data on substance dependence and behavioral reports of substance use and sexual risk in the past 30 days. Cluster analysis identified 3 EF subtypes: (a) high performing (good performance across all measures); (b) low performing (poor performance across all measures); and (c) poor IGT performance (impairment on the Iowa Gambling Task [IGT] and its variant, but good performance on all other tasks). The 3 subtypes did not differ in amount of substance use, but the low-performing subtype was associated with greater rates of substance dependence. The low-performing subtype reported the highest rates of sexual behavior and risk, while the poor-IGT-performance subtype reported the lowest rates of sexual risk taking. Global associations between substance use and sexual risk were strongest among the low-performing subtype, but event-level associations appeared strongest among individuals in the high-performing subtype. These data suggest complex associations between EF and sexual risk among substance users, and suggest that the relationship between substance use and sexual risk may vary by EF subtypes.

Abstract
OBJECTIVE To review the evidence for antiretroviral 'treatment as prevention' for HIV transmission among MSM. METHODS We reviewed studies that assess the biological plausibility that virally suppressive antiretroviral therapy (ART) reduces HIV infectiousness via anal intercourse and the epidemiologic evidence of whether ART has played a role in attenuating HIV incidence among MSM. RESULTS Although ART treatment among MSM is likely to provide some preventive benefit, it is unknown whether it will reduce HIV infectiousness via anal intercourse to the same extent as via penile-vaginal intercourse. Additional research is needed on the pharmacokinetic properties of specific antiretroviral agents in the gastrointestinal tract. Estimates of risk behaviors and the incidence of HIV among MSM before and after the introduction and expansion of ART suggest that the population-level protective benefits of ART may be attenuated by a number of factors, most notably, continuing or increasing frequency of condomless anal intercourse and incidence of other sexually transmitted infections (STIs). Additional studies are needed on the impact of ART on HIV sexual risk behaviors and transmission among MSM outside of developed countries in North America, western Europe, and Australia. CONCLUSION The benefits of treatment as prevention for MSM are highly plausible, but not certain. In the face of these unknowns, treatment guidelines for earlier ART initiation should be considered within a combination prevention strategy that includes earlier diagnosis, expanded STI treatment, and structural and behavioral interventions.
