The effects of alcohol and sexual arousal on determinants of sexual risk in men who have sex with men

Alcohol, Sexual Arousal, and Partner Familiarity as Predictors of Condom Negotiation: An Experience Sampling Study

Numerous contextual factors contribute to risky sexual decision-making among men who have sex with men (MSM), with experimental laboratory-based studies suggesting that alcohol consumption, sexual arousal, and partner familiarity have the potential to impact condom negotiations during sexual encounters. The purpose of the current study was to extend this line of inquiry outside of the laboratory and into the everyday lives of MSM. We collected six weeks of daily data on alcohol consumption and sexual behaviors from 257 moderate- and heavy-drinking MSM to examine the within- and between-subjects effects of alcohol consumption, average daily sexual arousal, and partner familiarity on condom negotiation processes during sexual encounters. We hypothesized that alcohol consumption, higher levels of average daily sexual arousal, and greater partner familiarity would all contribute to a reduced likelihood of condom negotiation prior to sexual activity, and that they would also affect the difficulty of negotiations. Contrary to hypotheses, none of these three predictors had significant within-subjects effects on condom negotiation outcomes. However, partner familiarity and average daily sexual arousal did exert significant between-subjects effects on the incidence of negotiation and negotiation difficulty. These findings have important implications for risk-reduction strategies in this population. They also highlight the challenges of reconciling results from experimental laboratory research and experience sampling conducted outside of the laboratory on sexual risk behavior.

Sexual alcohol expectancies moderate the relation between alcohol use and sexual behavior among men who have sex with men

BACKGROUND

HIV transmission remains a significant health concern for men who have sex with men (MSM) in the United States. Heavy episodic drinking (HED) is related to increased rates of condomless anal intercourse (CAI) among MSM, though evidence suggests that this association may vary by individual difference factors. The present secondary analysis tested whether sexual alcohol expectancies (SAEs) moderate the associations between frequency of HED and anal intercourse (AI) with and without a condom among moderate-to-heavy drinking HIV- MSM.

METHODS

Two hundred and forty-eight moderate-to-heavy drinking MSM completed self-report questionnaires including the Sexual Behavior Questionnaire, the Modified Daily Drinking Questionnaire, and the Sexual Alcohol Expectancies Questionnaire.

RESULTS

Negative binomial regressions indicated that SAEs moderated the association between frequency of HED and AI with a condom, but not between the frequency of HED and condomless AI (CAI).

CONCLUSIONS

These results suggest that stronger SAEs play a role in alcohol-related sexual behavior among MSM, but do not provide evidence that SAEs are associated with increased risk for HIV transmission through CAI.

Sexual Behaviors and Aggression in Gay Pornography

Previous studies have suggested a substantial number of men who have sex with men (MSM) have consumed and used pornography to learn about same-sex sexual behaviors. Yet, past research has focused almost exclusively on condom-use in the category of Gay pornography and ignored the types of sexual behaviors and aggression depicted within the content. This study examined aggression and sexual behaviors depicted in Gay online pornography (N = 415). We found fellatio and anal sex were the most common behaviors, occurring in roughly two-thirds of scenes, while kissing occurred in less than a third of scenes. Additionally, sexual aggression occurred in 31% of scenes, with spanking being the most common, occurring in 20% of scenes. Anal sex and forced fellatio were found to be predictors of physical aggression. These findings point to normalization of aggression and narrow sexual behaviors in Gay pornography, which may have implications for MSM's norm perceptions related to sexuality.

The Effect of Alcohol and Sexual Arousal on Explicit and Implicit Condom Attitudes and Intentions to Use a Condom

Alcohol and sexual arousal are contextual determinants of condomless sex. Dual-process theory postulates that two types of cognitive processing contribute to the regulation of behavior: one that is fast, intuitive and automatic, and another that is slower and deliberative. This study applied a dual-process model to investigate condomless sexual behavior, highlighting the potential importance of implicit attitudes in condomless sex. We investigated whether the impact of alcohol and sexual arousal on condom use-related attitudes and intentions was explained by diminished working memory capacity, as dual-process models suggest. We also investigated whether this effect could be explained by implicit and explicit attitudes toward condom use. Male participants (N = 30) were randomized using a 2 × 2 within-subjects design that manipulated alcohol intoxication (placebo vs. alcohol beverages) and sexual arousal (neutral vs. erotic movie clips). We measured participants' working memory capacity, intentions to use a condom, and explicit and implicit attitudes toward condom use. Significant main effects of alcohol intoxication and sexual arousal on working memory capacity were found. No significant interaction was found for the combined effect of alcohol intoxication and sexual arousal on intentions to use a condom. There was no significant effect of implicit attitudes on intentions to use a condom, although a trend toward significance (p = 0.06) was found for the effect of implicit attitudes on intentions to use a condom when participants were in a state of alcohol intoxication. Theoretical and practical implications of this study are discussed.

External validity of analogue sexual risk laboratory data

This article presents data on the external validity of an alcohol administration study of sexual decision-making in men who have sex with men (MSM) ages 21-50. Men (N = 135) randomized to alcohol (blood alcohol concentration [BAC] = .075%) or water control conditions reported intentions to engage in condomless anal intercourse (CAI) in response to video vignettes. Following the experiment participants provided 6 weeks of experience sampling method (ESM) data assessing intoxication, sexual arousal, partner relationship, and sexual behavior. Laboratory CAI intentions were hypothesized to predict future CAI behavior, and associations were hypothesized to be conditional upon sexual arousal and intoxication contextual factors as well as laboratory beverage condition. The hypotheses were partially supported. CAI intentions were correlated with subject proportions of days engaging in CAI (r = .29). A multilevel analysis indicated, on average, CAI intention predicted increased probability of CAI versus anal intercourse with a condom (relative risk ratio [RRR] = 1.43). There was mixed evidence of CAI intentions effects being conditional upon laboratory condition as well as arousal and intoxication contextual factors. Graphs of conditional marginal effects identified regions of significance. Effects of CAI intention for men in the alcohol condition on the CAI versus No Sex contrast were significant when sexual arousal was elevated. CAI intentions for men in the water control condition predicted a higher probability of CAI versus anal intercourse with a condom when intoxication was moderately elevated and/or arousal moderately low. The results support the external validity of alcohol administration experiments of sexual decision-making among MSM and, reciprocally, provide support for the validity of ESM assessment of sexual behavior.

The Relationship Between Alcohol and Drug Use, Compulsive Sexual Behavior, and Condomless Anal Sex in Men Who have Sex with Men: Analysis of Retrospectively-Reported Sexual Behavior

Men who have sex with men (MSM) are disproportionately impacted by HIV in the United States, and substance use and compulsive sexual behavior (CSB) are contributors to HIV risk behavior. This study sought to examine the direct and interactive effects of concurrent substance use and CSB on condomless anal sex (CAS) in a community sample of MSM (N = 200) utilizing a 90-day timeline follow-back assessment. Results indicated CSB did not directly increase risk for CAS when controlling for substance use and age. There was limited evidence for a direct effect of concurrent alcohol use on CAS, and no evidence for an interaction effect with CSB. The relationship between concurrent drug use and CAS was moderated by CSB, such that concurrent drug use was positively associated with CAS for those who screened positive for CSB, while the association was non-significant for those who screened negative. Implications and limitations of these findings are discussed.

Effects of Alcohol Intoxication on Sexual Decision-Making among Men Who Have Sex with Men (MSM): Alcohol's Influences on Self-Control Processes

This experiment tested mechanisms linking alcohol intoxication and analogue determinants of condomless anal intercourse (CAI) in a sample of 257 men who have sex with men (MSM). The two mechanisms tested were implicit approach biases toward CAI stimuli and executive working memory. Participants were randomized to 3 conditions (water control, placebo, or alcohol) and following beverage administration completed a working memory task, an Approach Avoidance Task of sexual vs. condom stimuli, and two video role-play vignettes of high-risk sexual scenarios. Sexual arousal and CAI intentions were assessed by self-report, and behavioral skills and risk exposure were derived from participants' role-play behavior. Estimation of four path models showed that the hypothesized mechanisms were supported for the CAI intention outcome, but the findings for the skills and risk exposure outcome were mixed. Implications for development and enhancement of HIV prevention interventions were discussed.

The Implicit Sexual Risk Assessment: A Pilot Study of a Novel Behavioral Task

Risky sexual behaviors are a significant public health concern. Laboratory experiments are necessary to identify causal determinants of risky sexual behavior. However, experiments often rely on analogue sexual risk behavior, assessed by self-reported intentions in response to a sexual scenario. Using behavioral tasks to assess risk taking may be a valuable addition to self-reported intention outcome measures. The Balloon Analogue Risk Task (BART) is a commonly used measure of general risk-taking. However, BART's associations with sexual risk-taking have been mixed. In this pilot study, we developed a task akin to the BART, the Implicit Sexual Risk Assessment (ISRA), which incorporates sexual stimuli. We hypothesized sexual arousal would increase risk taking on ISRA relative to BART. Using a within-persons experimental design, 79 participants (52% women, mean age = 19.5 (SD = 1.42)) were randomized to condition (i.e., arousal versus neutral) and completed the BART and ISRA tasks. As expected, sexual arousal was associated with increased risk-taking (i.e., adjusted pumps) on ISRA relative to BART. However, this was unexpectedly the result of decreased pumps on BART instead of increased pumps on ISRA. Neither BART nor ISRA were significantly associated with sexual risk behavior or intentions. Null findings are qualified by the fact that sexual arousal was not significantly associated with sexual risk intentions.

Risky sexual behavior and associated factors among sexually-experienced adolescents in Bangkok, Thailand: findings from a school web-based survey

Background

The risk of sexually transmitted infections (STI) arises when there is unsafe sexual activity. Unsafe sex often begins in the teenage years, and it will persist as long as there is the opportunity for risky sexual activity. The purpose of this study was to assess the sexual risk behaviors and related factors of sexually-active adolescents in educational institutions in Thailand.

Methods

This was cross-sectional survey using an Internet-based application in schools in Bangkok from November 2020 to February 2021 with a total of 6,167 high school and vocational students. The schools were selected by simple random sampling among institutions, and the students were systematically randomly selected, with an equal number of males and females. We used multivariable logistic regression to analyze associations and control confounding variables. Indicators of risky sex include: (1) Not using a condom; (2) Having more than one sex partner; (3) Having sex in exchange for cash or in-kind compensation; and (4) Having sex without consent.

Results

Of a total of 872 sexually-active participants, the mean age was 15.6 years, 66.9% were vocational students, 42.1% were male, 57.9% were female, and 69.5% had sex risk behavior. The multivariate logistic regression analysis identified the following statistically-significant factors related to risky sex: smokes cigarettes (AOR = 1.79; 95% CI 1.12–2.88); uses cannabis (AOR = 2.84; 95% CI 1.23–6.56); gambles (AOR = 1.81; 95% CI 1.28–2.55); has sex without contraception (AOR = 2.74; 95% CI 2.91–3.93); has a history of childhood sex abuse (AOR = 1.60; 95% CI 1.03–2.56).

Conclusions

Our findings suggest that, in designing and implementing sexual risk prevention programs for adolescents in educational settings, there is a need to highlight the role of substance abuse in relation to sexual risk behaviors. Programs should target both male and female students. Teenagers who use marijuana are more likely to be sexually active than those who have never used marijuana. These potential risks should be taken into account with respect to legalization of marijuana and recreational use of this drug.

Risky sexual behavior (RSB) is engaging in sexual practices that may increase vulnerability to a reproductive health problem. This study was conducted to assess the sexual risk behaviors of students living in Bangkok, which has the highest rates of STIs among regions in Thailand. Previous studies of RSB have focused on the general population age 18 years or older. By contrast, there is a dearth of studies on sex behavior among Thais under age 18 years. In addition, the present study aimed to explore the association of substance abuse and adverse childhood experiences (ACEs) with adolescent RSB. In this study, 14.1% of all students in the participating schools had ever had sex before. Using the study criteria, two out of three students in the sample had experienced RSB. The findings from this study may help inform programs and interventions aimed at reducing the negative health impacts associated with RSB, specifically STIs. The findings of the study should be relevant for health program managers, socio-behavioral researchers, and other stakeholders who design reproductive health intervention strategies for in-school adolescents.

'Empowering our people' to address depression, violence, and sexual risk among Native Americans with recent binge alcohol use

Background: This study was launched in response to an American Indian (AI) community's concern regarding the comorbid occurrence of substance use, poor mental health, and other risk factors on sexual health. The purpose of this manuscript was to assess the relationship between alcohol use, violence, depression and STI/HIV risk behaviors on the frequency of unprotected sex acts and number of sexual partners among AI adults.Methods: Specifically, this analysis examines sociodemographic characteristics, experience of sexual and physical violence, binge drinking, depression, and sexual risk taking among n = 281 AI adults ages 18-55. Regression models examine associations between the aforementioned risk factors, number of sex partners and number of unprotected sex acts, by depression status and sex, among participants.Results: Frequent binge drinking predicted frequency of unprotected sex for both males and females; ever experiencing physical violence was a powerful predictor of unprotected sex for females, but not males. Ever experiencing physical violence strongly predicted having multiple sexual partners for females but was related to decreased number of sexual partners for males. Females ever experiencing sexual violence had more sexual partners; this was not observed for males. Binge drinking predicted frequency of unprotected sex acts, regardless of depression status.Discussion: Interventions for AI adults seeking to reduce sexual health risk should reflect past violence victimization in sexual decision making, primarily among women. The significant role of binge alcohol use for modifying sexual decisions should be of prime focus and interventions should be personalized to address individuals' own alcohol use patterns. Additional research should explore how binge alcohol use moderates the relationship between depression and sexual risk.

How Alcohol Influences Mechanisms of Sexual Risk Behavior Change: Contributions of Alcohol Challenge Research to the Development of HIV Prevention Interventions

This paper examines the contributions of laboratory-based alcohol challenge research (ACR) to the development of HIV prevention interventions. Following a brief overview of HIV prevention interventions and related health behavior change models, we discuss how alcohol may influence mechanisms of behavior change. The paper highlights the value of ACR for: (1) elucidating mechanisms of action through which alcohol affects sexual risk behavior, (2) testing how alcohol may influence mechanisms thought to underlie HIV prevention interventions, (3) clarifying moderators of the causal influences of alcohol, (4) identifying novel intervention targets, and (5) developing strategies to reduce sexual risk among those who consume alcohol. We conclude with a discussion of the importance of using experimental research to identify mechanisms of behavior change that are specific to populations at high risk for HIV and outline some key implications for developing HIV prevention interventions that integrate the role of alcohol.

Daily Associations Among Alcohol Intoxication, Partner Familiarity, Participant Effortful Control, Urgency, and PrEP Uptake on Sexual Behavior in Men Who Have Sex with Men

The purpose of this study was to examine the effects of alcohol intoxication and its interaction with contextual or situation (partner familiarity) and individual differences variables (effortful control, urgency, and whether taking pre-exposure prophylaxis (PrEP) medication) on sexual behaviors in men who have sex with men (MSM), a subgroup for whom HIV continues to be a major public health problem in the U.S. The participants were 236 men recruited from two northeastern U.S. cities and aged 21-50 years, M = 27.8). These men participated in a 6-week (two 3-week sampling bursts) experience sampling method (ESM) study. The ESM data were collected via use of software installed on the participant's own or study-provided mobile phone. Individual differences variables were measured by participants' completing questionnaires measuring effortful control and urgency, and the participant's self-report of whether he was currently taking PrEP. The ESM data pertained to sexual behavior as well as situation variables of familiarity of relevant sexual partners and number of standard alcohol drinks consumed. The results generally were consistent with hypotheses, as alcohol intoxication showed a curvilinear relation to the occurrence of condomless anal intercourse. Furthermore, the likelihood of occurrence of condomless anal sex increased with increased familiarity of the sexual partner. Similarly, taking PrEP increased the likelihood of occurrence of condomless anal sex. At the same time, alcohol's effects were moderated by all three individual differences variables as expected, but the prediction that partner familiarity would moderate alcohol's effects on the occurrence of condomless sex was not supported. Clinical implications of the findings center on the application of the data to HIV prevention programs toward inclusion of more empirically supported, nuanced information on the relation between acute alcohol intoxication and sexual behavior. Directions for further research address the need for additional testing and refinement of a person × situation approach to alcohol and sexual behavior. Furthermore, it is argued that it is important to refine further the concept of sexual risk in the context of taking PrEP and to conduct more detailed, multivariate studies of the relation between taking PrEP and patterns of sexual behavior.

Do sexual expectancies and inhibitions predict high-risk sexual behaviours? Evidence from a cross-sectional survey among young psychoactive substance users in informal settlements in Kampala, Uganda

BACKGROUND

Psychoactive substance use is a public health challenge among young people in informal settlements. Though rarely examined, psychoactive substance use is linked to sexual expectancies and inhibitions, and consequently high-risk sexual behaviours. This study examined the association between sexual expectancies and inhibitions, and high-risk sexual behaviours among young psychoactive substance users (PSUs) in informal settlements in Kampala, Uganda.

METHODS

This cross-sectional study recruited 744 young PSUs from informal settlements in Kampala. Respondent driven sampling was used to recruit respondents. A 'modified' Poisson regression model was used for inferential statistics. Data were analysed using the Stata 14 software.

RESULTS

Of the 744 study participants, 45.6% believed that psychoactive substance use improves sexual performance; 43.3% believed that psychoactive substances make sex more pleasurable, and 53.3% believed that psychoactive substances give courage or confidence to approach a partner for sex. The belief that psychoactive substance use improves sexual performance (PR 1.14, 95% CI: 1.01-1.30), increases the likelihood of engaging in sex (PR 1.20, 95% CI: 1.04-1.40) or gives courage or confidence to approach a sexual partner (PR 1.21, 95% CI: 1.05-1.39) were associated with having sex while under the influence of psychoactive substances. The belief that a psychoactive substance user under the influence of psychoactive substances is more likely to engage in sex (PR 1.48, 95% CI: 1.15-1.90), and likely to find it difficult to refuse sex (PR 1.28, 95% CI: 1.06-1.55) were positively associated with engaging in multiple sexual partnerships. The belief that one easily forgets to use a condom when under the influence of psychoactive substances was positively associated with inconsistent condom use (PR 1.26, 95% CI: 1.09-1.45).

CONCLUSION

Psychoactive substance use expectancies associated with high-risk sexual behaviours included the belief that psychoactive substances improve sexual performance and improve confidence in approaching a sexual partner. Psychoactive substance use inhibitions associated with high-risk sexual behaviours included an increased likelihood of engaging in sexual intercourse, difficulties in refusing to engage in sexual intercourse, and forgetting to use condoms while intoxicated. Interventions targeting a reduction in high-risk sexual behaviour should integrate the impact of psychoactive substance use on sexual behaviour.

Cognitive-emotional mechanisms of alcohol intoxication-involved HIV-risk behavior among men who have sex with men (MSM)

Alcohol use is a key risk factor for HIV infection among men who have sex with men (MSM), primarily because it interferes with condom use. However, little is known about the cognitive-emotional mechanisms through which alcohol influences decisions to use condoms with high-risk partners among MSM. In this study, we tested whether alcohol-related deficits in inhibitory control and attention bias toward sexual cues (vs. condoms and neutral cues) accounted for increases in condomless anal sex (CAS) intentions after drinking among MSM. Heavy-drinking, high-risk MSM (N = 83) were randomly assigned to receive (a) alcohol, (b) placebo, or (c) control beverages before behavioral tasks assessing inhibitory control and attention bias, and a video-based sexual risk scenario that assessed several aspects of sexual decision making. Results showed that inhibitory control and attention bias to sexual cues did not mediate associations between intoxication and CAS intentions. Inhibitory control deficits also did not moderate the indirect effects of intoxication on CAS intentions through attention bias. Three-way interactions between alcohol/placebo condition, inhibitory control, and attention bias were also not significant. Together, these findings provide little evidence that these two processes play a significant role in alcohol-involved HIV risk, at least as assessed by the specific tasks used in this study.

Using ecological momentary assessment (EMA) to explore mechanisms of alcohol-involved HIV risk behavior among men who have sex with men (MSM)

BACKGROUND AND AIMS

Heavy drinking is associated with increased risk of incident HIV infection among men who have sex with men (MSM). Past studies suggest that this association may be due to the tendency for intoxication to interfere with condom use. However, research on potential causal mechanisms explaining this relationship has been limited primarily to laboratory studies. In this study, we tested several potential mediators of the relationship between alcohol use level and HIV risk behavior.

DESIGN

Ecological momentary assessment (EMA) methods conducted over a 30-day period.

SETTING AND PARTICIPANTS/CASES

MSM (n = 100) in the northeastern United States.

MEASUREMENTS

Participants completed daily diary surveys and up to six experience sampling surveys randomly prompted throughout the day.

FINDINGS

Very heavy levels of drinking (12+ drinks) increased the odds of engaging in any sex [odds ratio (OR) = 1.87, P < 0.001]. Coefficient products and 95% confidence intervals indicated that both subjective sexual arousal (OR = 1.52, P < 0.001) and sex intentions (OR = 1.74, P < 0.001) significantly mediated the association between very heavy drinking and the odds of sex. When participants reported sex, the odds of engaging in high-risk condomless anal sex (CAS) increased incrementally after drinking heavily (five to 11 drinks; OR = 3.27, P = 0.006) and very heavily (12+ drinks; OR = 4.42, P < 0.001). Only subjective sexual arousal significantly mediated the association between alcohol use level and high-risk CAS (OR = 1.16, P = 0.040).

CONCLUSIONS

Increases in subjective sexual arousal after drinking heavily appear to partly account for alcohol-related HIV risk behaviors in the daily lives of men who have sex with men. Alcohol's role in strengthening motivationally consistent emotional states may therefore play a more important role in facilitating alcohol-involved HIV risk than explicit sexual motivation.

Characteristics of Sex Events, Partners, and Motivations and Their Associations with HIV-Risk Behavior in a Daily Diary Study of High-Risk Men Who Have Sex with Men (MSM)

In the United States, men who have sex with men (MSM) continue to be at high-risk for HIV and other STIs, and condoms represent the most popular, affordable, and accessible method of prevention. Although a vast body of research has explored various factors associated with condom use in MSM, fewer studies have explored situation-level characteristics that affect their decisions about sex partners and condom use. Daily diary studies are well-suited to help improve our understanding of these event-level factors in detail, including the sex events themselves, partner characteristics, and motivations. As part of a larger study using ecological momentary assessment methods, high-risk MSM completed daily diary surveys about their sexual behavior on their smartphones each day for 30 days. This study explored detailed descriptive characteristics of sex events, partner characteristics, and motivations for sex and condom use, and examined whether specific aspects of these characteristics were associated with having condomless anal sex (CAS) with high-risk partners. High-risk CAS was common among MSM, with the majority of participants having met their partners online and many reporting sex the same day they met. Results showed that the odds of CAS were not higher with partners met online versus those met in other ways, but MSM were more likely to have asked online partners about their HIV status and testing history before sex. The odds of engaging in high-risk CAS was higher when MSM reported intimacy or self-assurance motives. Not having condoms readily available was a CAS motivation reported more commonly when MSM had sex with high-risk partners. Findings suggest that interventions should incorporate strategies that help MSM be safer specifically when meeting partners online and when having sex for intimacy or re-assurance. Interventions that remind MSM to carry condoms at opportune moments may also help reduce some HIV risk.

Working memory moderates the association between condom use intentions and behavior among moderate-to-heavy drinking men who have sex with men

Men who have sex with men (MSM) are a high-risk population for HIV infection and this risk is increased for those who consume alcohol. Condomless anal intercourse (CAI) is the central transmission risk factor for this population. This study examined whether individual differences in working memory moderated the association between intentions to use condoms and the frequency of CAI among MSM who engaged in anal intercourse over a subsequent 6-week period. Moderate- and heavy-drinking MSM (n = 207) completed questionnaires regarding alcohol use and condom use intentions and an operation span task to assess working memory at baseline. Participants then completed 6 weeks of morning surveys via a mobile phone app to assess anal intercourse frequency with and without condoms. Negative binomial regression analyses showed that the association between intentions to use condoms and episodes of CAI during the monitoring period was moderated by working memory such that intentions predicted CAI for those high in working memory but not those low in working memory. These results support the view that self-reported intentions may be less-likely to translate into health behaviors among those with poorer executive functioning skills.

Stimulant expectancy questionnaire for men who have sex with men: A measure of substance-related beliefs

ISSUE ADDRESSED

Stimulant use has been identified as a key risk factor for sexual behaviours leading to HIV transmission. Substance-related expectancies are associated with substance use and postsubstance use thoughts, feelings and behaviours. Expectancies held by specific cultural subgroups have rarely been investigated, particularly regarding a range of commonly used stimulants.

METHOD

The Stimulant Expectancy Questionnaire for Men who have Sex with Men (SEQ-MSM) was initially generated through consumer panel and interviews regarding the most commonly used stimulants among MSM in Australia (methamphetamine, amphetamines and ecstasy), with initial administration among 98 MSM to facilitate item reduction. A community sample of 427 MSM was used to validate the SEQ-MSM, with exploratory factor analysis (EFA; n = 202) and confirmatory factor analysis (CFA; n = 225).

RESULTS

EFA revealed three distinct substance reinforcement domains ('Enhanced sexual experience', 'Sexual communication and negotiation' and 'Cognitive impairment'). The scale was associated with stimulant consumption patterns (including greater expectancies regarding sexual enhancement among methamphetamine users), and the factor structure, comprising a final form of the MSM-SEQ, was confirmed through CFA.

CONCLUSIONS

The SEQ-MSM represents a reliable measure of outcome expectancies related to the range of commonly used stimulants among Australian MSM. Development of applied validation studies with the SEQ-MSM is a key next step in advancing health promotion, clinical interventions and research efforts to reduce harm (eg, HIV transmission) associated with stimulant use (particularly methamphetamine) among MSM. SO WHAT?: Objectives: This research maps expectancies specific among gay and men who have sex with men (MSM), and relationships between expectancies and stimulant use patterns and behaviours postuse - including sexual activity (eg, condomless anal sex).

Moderated Mediation of Perceived Intoxication and Sexual Arousal on Determinants of Sexual Risk Behavior in Men Who Have Sex with Men

Behavioral interventions remain the preferred strategy for reducing HIV-related risk behavior among men who have sex with men (MSM), one of the populations most affected by HIV. To improve intervention efforts, research is needed to identify cognitive-motivational factors that may play a role in sexual risk behaviors among MSM. This study sought to replicate and extend previous work from a heterosexual population that identified a serial mediation effect of perceived intoxication and subjective sexual arousal in the relationship between alcohol consumption and determinants of sexual risk in a population of MSM. Exploratory moderated mediation analyses tested subjective sexual arousal as a moderator of the indirect effect of alcohol consumption on determinants of sexual risk via perceived intoxication. Participants (N = 117 MSM, ages 21-50) were randomly assigned to one of six experimental conditions based on two manipulations: beverage condition (alcohol, placebo, or control) and sexual arousal (low or high). Dependent measures were likelihood to engage in risky sex and condom negotiation skills. Results did not support the serial mediation effect but showed some support for the moderated mediation model in the prediction of behavioral skills. Implications for alcohol and arousal myopia theories of risky behavior and HIV prevention efforts are discussed.

A Preliminary Randomized Controlled Trial of Game Plan, A Web Application to Help Men Who Have Sex with Men Reduce Their HIV Risk and Alcohol Use

Alcohol use is a key risk factor for HIV infection among men who have sex with men (MSM). Past studies show that brief motivational interventions (BMI) can increase the use of prevention methods (e.g., condoms), reduce alcohol use, and can be adapted for web-based delivery. However, few studies have explored these interventions' effects in MSM. Forty high-risk, heavy drinking MSM who sought rapid HIV testing were randomly assigned to receive either (1) standard post-test counseling (SPC) alone, or (2) SPC plus Game Plan (GP), a tablet tablet-based BMI for alcohol use and HIV risk. Over three months of follow-up, GP participants reported 24% fewer heavy drinking days, 17% fewer alcohol problems, and 50% fewer new anal sex partners than controls. GP participants also reported fewer high-risk condomless anal sex events than controls, but these differences were not significant. These initial results suggest that web-based BMIs may be promising tools to help MSM reduce health risk behaviors.

Alcohol and Sexual Health Behavior: "What We Know and How We Know It"

Alcohol, despite salutary associations with sexuality, has been implicated in sexual health problems. This review examines the relationship between alcohol and outcomes related to sexual health. Methodological considerations limiting causal assertions permissible with nonexperimental data are discussed, as are advantages of experimental methods. Findings from laboratory experiments are reviewed evaluating causal effects of acute alcohol intoxication on a variety of outcomes, including sexual arousal, sexual desire, orgasm, and sexual risk behaviors related to sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Several variables exerting mediating and moderating influences are identified. It is concluded that acute alcohol intoxication is capable of exerting a causal impact on multiple constituent components of sexual responding related to sexual health. Both alcohol expectancy and alcohol myopia theories have been supported as explanations for these causal effects. Furthermore, for sexual risk behavior, noteworthy recent developments include research highlighting the importance of women's sexual victimization history and men's condom use resistance. Limitations and implications associated with this body of research are also discussed.

Defining “High-risk Sexual Behavior” in the Context of Substance Use

Introduction: Sexual behavior is a behavior exhibited by individuals to gratify one of their basic needs, that is the sexual need. Often the way in which sexual behavior is practiced may lead to negative consequences. However, the definition of a sexual behavior as risky varies with regards to culture, gender, age, and the threshold.

Objectives: This review aims to study different definitions of high-risk sexual behavior available in literature, the differences in the prevalence of various risks associated with risky sex in substance-using population as compared to general population, and eventually formulating a tentative definition of “high-risk sexual behavior” in the context of substance use. Current evidence and results of literature search as we have entered into the epidemic of human immunodeficiency virus globally, it is important clinically as well as from the public health perspective to define high-risk sexual behavior discretely helping the researchers quantify the burden and the clinicians focus on the population at risk. High-risk sexual behavior has often been discussed and studied in various studies till date. However, literature lacks a discrete definition of high-risk sexual behavior. Risky sex (or high-risk sexual behavior) has been variably defined in different studies. Majority of the definitions in the studies focus on sexually transmitted infection, especially human immunodeficiency virus. A few studies talk about unintended pregnancies or abortions.

Conclusion: The association between high-risk sexual behavior and substance use has been well established. Further research is warranted to obtain a definition which has greater precision and clinical utility, and which can be integrated in preventive and promotive pursuits.

Causal Effects of Alcohol Intoxication on Sexual Risk Intentions and Condom Negotiation Skills Among High-Risk Men Who Have Sex with Men (MSM)

Alcohol use is a key risk factor for HIV infection among MSM, in part because intoxication may interfere with the use of prevention methods like condoms. However, few studies have examined whether this is due to alcohol's pharmacological or expectancy effects or explored the specific aspects of sexual decision-making that may be affected. In this study, high-risk, heavy drinking MSM (N = 121) were randomly assigned to receive either (1) alcohol beverages, (2) placebo beverages, or (3) control beverages, before navigating a video-based sexual risk scenario that assessed several aspects of sexual decision-making. Results showed that condom use intentions and negotiation behaviors were lower among alcohol and placebo participants compared with controls, but that few significant differences emerged between the alcohol and placebo groups. These findings contrast with similar past studies, and suggest that alcohol's expectancy effects may play a role in sexual decision-making.

Effects of Sexual Arousal and Alcohol Cues on Acute Motivation for Alcohol

Reward-related stimuli can induce motivation to obtain rewards both within and across domains. We tested within- and cross-domain effects of environmental context (mock bar vs. laboratory) and sexually arousing stimuli (pornography vs. nature film) on acute motivation for alcohol as measured by a state-based alcohol purchase task in 109 male and female college students. Our results showed significant effects of both sexual arousal and environmental context on acute motivation for alcohol. A limited subsample analysis (N = 84) revealed significant effects of both sexual arousal and environmental context conditions on elasticity. Consistent with hypotheses, the presence of either sex- or alcohol-related cues increased acute motivation for alcohol and decreased sensitivity to costs of drinking. Furthermore, there was a significant video × laboratory condition interaction in the elasticity analysis. Our findings suggest that both sexually arousing stimuli and incidental environmental alcohol cues may significantly increase the effort one will expend to consume alcohol and thus the potential for risky drinking behavior. We believe this is the first experiment to use demand curves to present evidence of cross-domain effects of sexually arousing stimuli on acute motivation for alcohol.

Meta-Analysis of Alcohol and Serodiscordant Condomless Sex Among People Living with HIV

While observational studies have found that alcohol consumption is associated with serodiscordant condomless sex among people living with HIV (PLHIV), no meta-analysis has yet examined this trend. We conducted a meta-analysis to synthesize empirical evidence on the association between alcohol and condomless sex with partners at risk of HIV acquisition. To meet inclusion criteria, studies: (1) specifically targeted PLHIV or provided stratified data for HIV-infected participants; (2) provided a quantitative measure of alcohol use; (3) provided a quantitative measure of condomless sex with serodiscordant partners; and (4) reported the results of statistical tests examining the relationship between alcohol use and serodiscordant condomless sex. Using random-effects models, weighted effect sizes were calculated. Three separate analyses were conducted to examine serodiscordant condomless sex in association with any alcohol consumption, binge/problematic drinking, and alcohol in a sexual context. A total of 36 independent effect sizes from 27 studies (including 25,065 HIV-infected participants) were pooled in the meta-analysis. Any alcohol consumption, binge/problematic drinking, and alcohol use in a sexual context were each associated with condomless sex with serodiscordant partners [OR 1.64 (95% CI 1.46-1.85); OR 1.65 (95% CI 1.14-2.39); OR 2.88 (95% CI 2.01-4.12), respectively]. Meta-analytic findings demonstrate a consistent positive relationship between alcohol use and serodiscordant condomless sex among PLHIV. Future public health programming for HIV-infected individuals needs to address the role of alcohol consumption in sexual risk-taking behavior.

Daily associations between alcohol and sexual behavior in young adults

We tested within-person effects of alcohol on sexual behavior among young adults in a longitudinal burst design (N = 213, 6,487 days) using data collected from a previously published parent study. We differentiated effects of alcohol on likelihood of sexual activity versus use of protection against sexually transmitted diseases (STDs) or pregnancy on intercourse occasions by testing a multilevel multinomial model with 4 outcomes (no sex, oral sex without intercourse, protected intercourse, and unprotected intercourse). At the within-person level, effects of alcohol were hypothesized to be conditional upon level of intoxication (i.e., curvilinear effect). We also tested effects of four between-person moderators: gender, typical length of relationship with sexual partners, and two facets of self-control (effortful control and reactivity). Consistent with our hypothesis, low-level intoxication was associated with increased likelihood of engaging in oral sex or protected intercourse (relative to no sex) but was not related to likelihood of unprotected intercourse. The effect of intoxication on unprotected versus protected intercourse was an accelerating curve, significantly increasing likelihood of unprotected intercourse at high levels of intoxication. Between-person factors moderated associations between intoxication and sexual behavior. Effects of intoxication on both protected and unprotected intercourse were diminished for individuals with more familiar sexual partners. Effortful control exhibited a protective effect, reducing the effects of intoxication on likelihood of unprotected intercourse. Hypothesized effects of reactivity were not supported. Intoxication was a stronger predictor of oral sex and protected intercourse (but not unprotected intercourse) for women relative to men. Results highlight the inherent complexities of the alcohol-sexual behavior nexus. (PsycINFO Database Record

HIV-related thought avoidance, sexual risk, and alcohol use among men who have sex with men

HIV-related "cognitive escape" refers to a tendency to avoid thoughts associated with HIV, which may be particularly common among men who have sex with men (MSM) who are often inundated with HIV information, potentially to the point of fatigue. HIV-related cognitive escape is associated with increased sexual risk behaviors, such as condomless sex, and heavier alcohol use patterns. Other studies show that some MSM may use alcohol specifically to facilitate sex. These sexual motives for drinking (SMDs) could be one mechanism whereby cognitive escape leads to health risk behaviors. In this study, we tested models exploring whether cognitive escape was associated with markers of sex risk (condom use, number of sex partners) and alcohol use/problems, and examined whether SMDs mediated these associations. Heavy drinking, HIV-negative men (N = 196) aged ≥ 21 years who self-reported past year condomless anal sex with men completed assessments as part of a larger study. Results suggest that cognitive escape was associated with higher number of anal sex partners (incidence rate ratio [IRR] = 1.50, SE = 0.04, p < .001), decreased condom use (B = -0.30, SE = 0.14, p = .028), and increased alcohol-related problems (IRR = 1.28, SE = 0.07, p = .001) but not with drinking quantity. Sexual motives for drinking appeared to partially mediate the observed relationship between cognitive escape and alcohol-related problems, but other relationships did not show evidence of mediation. Findings suggest that those who tend to avoid HIV-related thoughts may be at increased risk for HIV and alcohol-related problems. Drinking to facilitate sex may partially account for the higher risk for alcohol-related problems conferred by cognitive escape. Alcohol interventions for MSM may be more effective if they address alcohol's role in coping with HIV threat and in facilitating sex under these circumstances.

Acute Alcohol Consumption Directly Increases HIV Transmission Risk: A Randomized Controlled Experiment

BACKGROUND

Alcohol consumption has frequently been purported as a driver of condomless sex and HIV transmission, but to date, experimental evidence for the causal risk-taking impact of alcohol among HIV-positive populations is lacking. The present experiment sought to determine whether acute alcohol consumption has a direct causal impact on condomless sex intentions among HIV-positive men-who-have-sex-with-men (MSM), and to assess whether alcohol's impact differs between MSM who are HIV-positive versus HIV-negative.

METHODS

In a randomized controlled alcohol administration experiment, HIV-positive and HIV-negative MSM were brought into a specialized barroom laboratory and randomly assigned to beverage consumption condition: alcohol (target blood alcohol concentration = 0.080%), placebo alcohol (target blood alcohol concentration = 0.000%), or water (control). Participants then underwent a video-based sexual arousal manipulation (sexually aroused/nonaroused) and indicated their intentions to engage in condom-protected and condomless sexual acts in a standardized paradigm. The primary outcome entailed intentions to engage in condomless receptive and condomless insertive anal sex.

RESULTS

A total of 282 MSM (141 HIV-positive; 141 HIV-negative) completed experimental procedures. MSM who received alcohol reported significantly stronger intentions to engage in condomless sex than those who received placebo alcohol or water (F(1,274) = 9.43, P = 0.002). The impact of alcohol did not differ between HIV-positive and HIV-negative MSM (F(1,274) = 1.86, P = 0.174).

CONCLUSIONS

The present investigation entailed the first risk-focused alcohol administration experiment to involve an HIV-positive sample, and results demonstrated that consuming alcohol had an independent, causal impact on intentions to engage in sexual behaviors that can result in HIV transmission. Findings strongly suggest that alcohol-focused initiatives should be incorporated into HIV prevention efforts.

Does being drunk or high cause HIV sexual risk behavior? A systematic review of drug administration studies

HIV sexual risk behavior is broadly associated with substance use. Yet critical questions remain regarding the potential causal link between substance use (e.g., intoxication) and HIV sexual risk behavior. The present systematic review was designed to examine and synthesize the existing literature regarding the effects of substance administration on HIV sexual risk behavior. Randomized controlled experiments investigating substance administration and HIV sexual risk behavior (e.g., likelihood of condom use in a casual sex scenario) were included. Across five databases, 2750 titles/abstracts were examined and forty-three total peer reviewed published manuscripts qualified (few were multi-study manuscripts, and those details are outlined in the text). The majority of articles investigated the causal role of acute alcohol administration on HIV sexual risk behavior, although one article investigated the effects of acute THC administration, one the effects of acute cocaine administration, and two the effects of buspirone. The results of this review suggest a causal role in acute alcohol intoxication increasing HIV sexual risk decision-making. Although evidence is limited with other substances, cocaine administration also appears to increase sexual risk, while acute cannabis and buspirone maintenance may decrease sexual risk. In the case of alcohol intoxication, the pharmacological effects independently contribute to HIV sexual risk decision-making, and these effects are exacerbated by alcohol expectancies, increased arousal, and delay to condom availability. Comparisons across studies showed that cocaine led to greater self-reported sexual arousal than alcohol, potentially suggesting a different risk profile. HIV prevention measures should take these substance administration effects into account. Increasing the amount of freely and easily accessible condoms to the public may attenuate the influence of acute intoxication on HIV sexual risk decision-making.

Alcohol-induced retrograde facilitation renders witnesses of crime less suggestible to misinformation

RATIONALE

Research has shown that alcohol can have both detrimental and facilitating effects on memory: intoxication can lead to poor memory for information encoded after alcohol consumption (anterograde amnesia) and may improve memory for information encoded before consumption (retrograde facilitation). This study examined whether alcohol consumed after witnessing a crime can render individuals less vulnerable to misleading post-event information (misinformation).

METHOD

Participants watched a simulated crime video. Thereafter, one third of participants expected and received alcohol (alcohol group), one third did not expect but received alcohol (reverse placebo), and one third did not expect nor receive alcohol (control). After alcohol consumption, participants were exposed to misinformation embedded in a written narrative about the crime. The following day, participants completed a cued-recall questionnaire about the event.

RESULTS

Control participants were more likely to report misinformation compared to the alcohol and reverse placebo group.

CONCLUSION

The findings suggest that we may oversimplify the effect alcohol has on suggestibility and that sometimes alcohol can have beneficial effects on eyewitness memory by protecting against misleading post-event information.

Using Ecological Momentary Assessment (EMA) to Study Sex Events Among Very High-Risk Men Who Have Sex with Men (MSM)

MSM continue to represent the largest share of new HIV infections in the United States each year due to high infectivity associated with unprotected anal sex. Ecological momentary assessment (EMA) has the potential to provide a unique view of how high-risk sexual events occur in the real world and can impart detailed information about aspects of decision-making, antecedents, and consequences that accompany these events. EMA may also produce more accurate data on sexual behavior by assessing it soon after its occurrence. We conducted a study involving 12 high-risk MSM to explore the acceptability and feasibility of a 30 day, intensive EMA procedure. Results suggest this intensive assessment strategy was both acceptable and feasible to participants. All participants provided response rates to various assessments that approached or were in excess of their targets: 81.0 % of experience sampling assessments and 93.1 % of daily diary assessments were completed. However, comparing EMA reports with a Timeline Followback (TLFB) of the same 30 day period suggested that participants reported fewer sexual risk events on the TLFB compared to EMA, and reported a number of discrepancies about specific behaviors and partner characteristics across the two methods. Overall, results support the acceptability, feasibility, and utility of using EMA to understand sexual risk events among high-risk MSM. Findings also suggest that EMA and other intensive longitudinal assessment approaches could yield more accurate data about sex events.

Alcohol Use and Human Immunodeficiency Virus (HIV) Infection: Current Knowledge, Implications, and Future Directions

Alcohol use is common among people living with human immunodeficiency virus (HIV). In this narrative review, we describe literature regarding alcohol's impact on transmission, care, coinfections, and comorbidities that are common among people living with HIV (PLWH), as well as literature regarding interventions to address alcohol use and its influences among PLWH. This narrative review identifies alcohol use as a risk factor for HIV transmission, as well as a factor impacting the clinical manifestations and management of HIV. Alcohol use appears to have additive and potentially synergistic effects on common HIV-related comorbidities. We find that interventions to modify drinking and improve HIV-related risks and outcomes have had limited success to date, and we recommend research in several areas. Consistent with Office of AIDS Research/National Institutes of Health priorities, we suggest research to better understand how and at what levels alcohol influences comorbid conditions among PLWH, to elucidate the mechanisms by which alcohol use is impacting comorbidities, and to understand whether decreases in alcohol use improve HIV-relevant outcomes. This should include studies regarding whether state-of-the-art medications used to treat common coinfections are safe for PLWH who drink alcohol. We recommend that future research among PLWH include validated self-report measures of alcohol use and/or biological measurements, ideally both. Additionally, subgroup variation in associations should be identified to ensure that the risks of particularly vulnerable populations are understood. This body of research should serve as a foundation for a next generation of intervention studies to address alcohol use from transmission to treatment of HIV. Intervention studies should inform implementation efforts to improve provision of alcohol-related interventions and treatments for PLWH in healthcare settings. By making further progress on understanding how alcohol use affects PLWH in the era of HIV as a chronic condition, this research should inform how we can mitigate transmission, achieve viral suppression, and avoid exacerbating common comorbidities of HIV and alcohol use and make progress toward the 90-90-90 goals for engagement in the HIV treatment cascade.

Toward Development of Enhanced Preventive Interventions for HIV Sexual Risk among Alcohol-Using Populations: Confronting the 'Mere Pause from Thinking'

The papers in this issue detail state-of-the science knowledge regarding the role of alcohol use in HIV/AIDS risk, as well as offer suggestions for ways forward for behavioral HIV prevention for at-risk alcohol-using populations. In light of recent evidence suggesting that the anticipated uptake of the newer biomedical HIV prevention approaches, prominently including pre-exposure prophylaxis, has been stalled owing to a host of barriers, it has become ever more clear that behavioral prevention avenues must continue to receive due consideration as a viable HIV/AIDS prevention approach. The papers collected here make a valuable contribution to "combination prevention" efforts to curb HIV spread.

Research on the Effects of Alcohol and Sexual Arousal on Sexual Risk in Men who have Sex with Men: Implications for HIV Prevention Interventions

The purpose of this paper was to describe and appraise the research evidence on the effects of acute alcohol intoxication and sexual arousal on sexual risk behaviors in men who have sex with men (MSM) and to examine its implications for design of HIV prevention interventions that target MSM. Toward that end, the paper begins with a discussion of research on sexual arousal in men and alcohol and their acute effects on sexual behaviors. This is followed by a review of empirical evidence on the combined acute effects of alcohol and sexual arousal in heterosexual men (the large majority of studies) and then in MSM. The empirical evidence and related theoretical developments then are integrated to derive implications for developing effective HIV prevention interventions that target MSM.

Acute Effects of Intoxication and Arousal on Approach/Avoidance Biases Toward Sexual Risk Stimuli in Heterosexual Men

This study tested the effects of alcohol intoxication and physiological arousal on cognitive biases toward erotic stimuli and condoms. Ninety-seven heterosexual men were randomized to 1 of 6 independent conditions in a 2 (high arousal or control) × 3 (alcohol target BAC = 0.08, placebo, or juice control) design and then completed a variant of the Approach-Avoidance Task (AAT). The AAT assessed reaction times toward approaching and avoiding erotic stimuli and condoms with a joystick. Consistent with hypotheses, the alcohol condition exhibited an approach bias toward erotic stimuli, whereas the control and placebo groups exhibited an approach bias toward condom stimuli. Similarly, the participants in the high arousal condition exhibited an approach bias toward erotic stimuli and the low arousal control condition exhibited an approach bias toward condoms. The results suggest that acute changes in intoxication and physiological arousal independently foster biased responding toward sexual stimuli and these biases are associated with sexual risk intentions.

Alcohol Use Predicts Sexual Decision-Making: A Systematic Review and Meta-Analysis of the Experimental Literature

Alcohol is associated with HIV and other sexually transmitted infections through increased sexual risk-taking behavior. Establishing a causal link between alcohol and sexual behavior has been challenging due to methodological limitations (e.g., reliance on cross-sectional designs). Experimental methods can be used to establish causality. The purpose of this meta-analysis was to evaluate the effects of alcohol consumption on unprotected sex intentions. We searched electronic bibliographic databases for records with relevant keywords; 26 manuscripts (k = 30 studies) met inclusion criteria. Results indicate that alcohol consumption is associated with greater intentions to engage in unprotected sex (d +s = 0.24, 0.35). The effect of alcohol on unprotected sex intentions was greater when sexual arousal was heightened. Alcohol consumption is causally linked to theoretical antecedents of sexual risk behavior, consistent with the alcohol myopia model. Addressing alcohol consumption as a determinant of unprotected sex intentions may lead to more effective HIV interventions.

The Association Between Alcohol Consumption and Condom Use: Considering Correlates of HIV Risk Among Black Men Who Have Sex with Men

Epidemiological data indicate Black men who have sex with men (MSM) are the most at-risk group for HIV infection. However, the factors driving this disparity are not fully understood. Condom use remains a significant point of intervention in mitigating sexually transmitted infections. Alcohol consumption is highly prevalent among Black MSM, has a significant role in the culture of sex, and may significantly interfere with condom use. This review will examine the relationship between alcohol consumption and condom use among Black MSM. In this review we, (a) discuss the prevalence of alcohol use among MSM and its association with condom use; (b) consider the role of alcohol in the culture of MSM; (c) review the literature on the relationship between alcohol and condom use; and (d) discuss the role of several empirically-supported moderating variables in strengthening the relationship between alcohol use and noncondom use. This review places the finding and implications for HIV risk among Black MSM in the context of the broader literature on MSM.

Pervasive Heavy Alcohol Use and Correlates of Increasing Levels of Binge Drinking among Men Who Have Sex with Men, San Francisco, 2011

Heavy episodic drinking, "binge drinking", is highly prevalent among men who have sex with men (MSM) and is associated with sexual risk behaviors and HIV seroconversion in this population. We characterized the magnitude of binge drinking and explored correlates of increasing levels of binge drinking among MSM in San Francisco. In this study, 67% of MSM reported binge drinking in the prior year. The mean number of drinking days in the past month was 11.6. On average, we estimate that 2,699,372 drinks are consumed by MSM in San Francisco every month. Increasing levels of binge drinking was independently associated with younger age, modest income, being born in the United States, never accessing alcohol treatment and reporting unprotected insertive anal intercourse. Our findings underscore the need to target effective strategies to address heavy alcohol consumption and highlight the urgent need to develop novel interventions beyond traditional alcohol treatment settings among MSM.

Systematic review of interventions to reduce problematic alcohol use in men who have sex with men

ISSUES

Rates of heavy drinking, alcohol problems and alcohol-related disorders are high among men who have sex with men (MSM) and are an important public health issue. Associations between heavy drinking and human immunodeficiency virus (HIV) acquisition among MSM also suggest that drinking may have more severe and chronic consequences for this population relative to others. Consequently, effective interventions to reduce heavy drinking and alcohol-related risk factors among MSM are needed.

APPROACH

We conducted a systematic review of randomised controlled trials of interventions to reduce heavy drinking and/or alcohol-related problems among MSM. We searched five electronic databases, screened 3722 records and identified 5 studies involving 1022 participants that satisfied inclusion criteria, which included having: (i) incorporated a comparison condition; (ii) randomised participants to groups; and (iii) reported quantitative outcomes.

KEY FINDINGS

The methodological quality of studies varied, and meta-analysis was not conducted because of heterogeneity in intervention approaches and outcomes. Studies provided preliminary support for the use of motivational interviewing/motivational enhancement-based interventions (MI) and hybrid MI and cognitive behavioural therapy treatments for heavy drinking among MSM over no treatment. Perhaps the most important conclusion of this review, however, is that well-designed, theoretically informed research focused on establishing the efficacy of interventions for hazardous drinking and alcohol use disorders among MSM is alarmingly scarce.

CONCLUSIONS

Effective interventions to reduce hazardous drinking among MSM and prevent key alcohol-related outcomes, including risk for HIV transmission and health problems among HIV-positive MSM, are needed to mitigate health disparities in this population.

Daily associations between alcohol use and unprotected anal sex among heavy drinking HIV-positive men who have sex with men

Men who have sex with men (MSM) account for the largest proportion of new HIV infections in the United States. Alcohol may facilitate HIV transmission by increasing unprotected anal sex, but few studies have focused on transmission behaviors in HIV-positive MSM. This study explored daily associations between alcohol use and sexual behavior among heavy drinking HIV-positive MSM using a 30-day Timeline Followback interview. Results of generalized estimating equations indicated that greater alcohol consumption on a given day was associated with a linear increase in the odds of having unprotected anal sex with partners of any HIV status. However, the odds of reporting unprotected anal sex with HIV-negative or HIV-status unknown partners increased in a curvilinear fashion, occurring primarily at very heavy levels of use (12+ drinks). Results suggest that very heavy drinking increases the risk of engaging in sexual behavior that has the potential for transmitting HIV to other men.

Binge drinking and risky sexual behavior among HIV-negative and unknown HIV status men who have sex with men, 20 US cities

BACKGROUND

Men who have sex with men (MSM) represent over half of new HIV infections in the United States. It is important to understand the factors associated with engaging in risky sexual behavior to develop effective prevention interventions. Binge drinking (≥5 drinks on ≥1 occasion) is the most common form of excessive alcohol consumption. This study examines the relationship between binge drinking and sexual risk behaviors among MSM who are current drinkers and who were either HIV-negative or unaware of their HIV status.

METHODS

Using the 2011 National HIV Behavioral Surveillance system and multivariable Poisson models with robust error estimates, we assessed the association between binge drinking and sexual risk behaviors among current drinkers. Prevalence ratios (PR) and 95% confidence intervals (CI) are presented.

RESULTS

Overall, 85% of MSM were current drinkers, and 59% of MSM who drank reported ≥1 episode of binge drinking in the preceding 30 days. In multivariable models, binge drinking was associated with condomless anal intercourse (CAI) at last sex with an HIV-positive or unknown status partner (receptive: PR 1.3, 95% CI 1.1-1.6; insertive: PR 1.2, 95% CI 1.0-1.4), having exchanged sex for money or drugs at last sex (PR: 1.4, 95% CI 1.1-1.7), having concurrent partners in the past year (PR: 1.1, 95% CI 1.1-1.2), and having more CAI partners in the past year (PR: 1.2, 95% CI 1.0-1.4) compared to non-binge drinkers.

CONCLUSIONS

Evidence-based strategies for reducing binge drinking could help reduce risky sexual behavior among MSM.

Assessing sexual motives for drinking alcohol among HIV-positive men who have sex with men

Individuals who drink alcohol for the explicit motive of facilitating or enhancing sex may be more likely to engage in risky sexual behavior, including having sex under the influence of alcohol. However, efforts to assess sexual motives for drinking (SMDs) have been very limited to date. We examined the psychometric properties of a 5-item measure of SMDs in a sample of HIV-positive heavy drinking men who have sex with men. Findings provided excellent support for the scale's internal consistency and concurrent validity with a well-established measure of sexual alcohol expectancies (SAEs). Good discriminant validity was also established, as SMDs were correlated with other drinking motives but uniquely predicted the proportion of sex acts occurring under the influence of alcohol and other drugs, over and above other drinking motives and SAEs. SMDs were not significantly associated with unprotected anal intercourse. Adjusting for alcohol problem severity, higher SMDs were associated with lower willingness to consider changing drinking. Results suggest this measure of SMDs exhibits sound psychometric properties and may be useful in studies examining the association between alcohol use and sexual behavior. (PsycINFO Database Record

Sexually explicit online media and sexual risk among men who have sex with men in the United States

This study aimed to describe sexually explicit online media (SEOM) consumption among men who have sex with men (MSM) in the United States and examine associations between exposure to unprotected anal intercourse (UAI) in SEOM and engagement in both UAI and serodiscordant UAI. MSM in the U.S. who accessed a men-seeking-men website in the past year (N = 1,170) were recruited online for a cross-sectional, Internet-based survey of sexual risk and SEOM consumption. In the 3 months prior to interview, more than half (57 %) of the men reported viewing SEOM one or more times per day and almost half (45 %) reported that at least half of the SEOM they viewed portrayed UAI. Compared to participants who reported that 0-24 % of the SEOM they viewed showed UAI, participants who reported that 25-49, 50-74, or 75-100 % of the SEOM they viewed portrayed UAI had progressively increasing odds of engaging in UAI and serodiscordant UAI in the past 3 months. As SEOM has become more ubiquitous and accessible, research should examine causal relations between SEOM consumption and sexual risk-taking among MSM as well as ways to use SEOM for HIV prevention.

Sexually explicit media on the internet: a content analysis of sexual behaviors, risk, and media characteristics in gay male adult videos

Recent research suggests that viewing sexually explicit media (SEM), i.e., adult videos, may influence sexual risk taking among men who have sex with men. Despite this evidence, very little is known about the content of gay male SEM on the Internet, including the prevalence of sexual risk behaviors and their relation to video- and performer-characteristics, viewing frequency, and favorability. The current study content analyzed 302 sexually explicit videos featuring male same-sex performers that were posted to five highly trafficked adult-oriented websites. Findings revealed that gay male SEM on the Internet features a variety of conventional and nonconventional sexual behaviors. There was a substantial prevalence of unprotected anal intercourse (UAI) (34 %) and was virtually the same as the prevalence of anal sex with a condom (36 %). The presence of UAI was not associated with video length, amateur production, number of video views, favorability, or website source. However, the presence of other potentially high-risk behaviors (e.g., ejaculation in the mouth, and ejaculation on/in/rubbed into the anus) was associated with longer videos, more views, and group sex videos (three or more performers). The findings of high levels of sexual risk behavior and the fact that there was virtually no difference in the prevalence of anal sex with and without a condom in gay male SEM have important implications for HIV prevention efforts, future research on the role of SEM on sexual risk taking, and public health policy.

Effects of alcohol cues and alcohol intoxication on drug use expectancies among men who have sex with men

Although alcohol and drug use have been identified as HIV-risk factors for men who have sex with men (MSM), little is known about how they interact. An alcohol administration paradigm was used to examine alcohol's cue and pharmacological effects on perceived drug use benefits and consequences in 117 MSM. Planned contrasts indicated that those in the alcohol cue (i.e., placebo) condition reported lower perceived drug consequences compared to controls. No cue effects were found for drug benefits. There was no pharmacological effect of alcohol as compared to alcohol cue on either outcome. Findings suggest that alcohol cues may influence the perception of consequences related to drug use, which has implications for health interventions targeting substance use and HIV risk.

Perceived importance of five different health issues for gay and bisexual men: implications for new directions in health education and prevention

This study assessed the perceived importance of five health issues for gay and bisexual men (N = 660) using time-space sampling in gay bars/clubs and bathhouses in New York City: "HIV & STDs," "Drugs & Alcohol," "Body Image," "Mental Health," and "Smoking." This study compared ratings based on demographic differences, recent substance use, recent sexual risk behavior, and whether or not participants owned a smart device (e.g., "smart" phone, iPad, iPod touch). Contrary to research indicating that gay and bisexual men may be experiencing HIV prevention fatigue, this study identified that HIV and STIs were perceived as most important. Drugs and alcohol and mental health were also rated high, suggesting that providers may be well served to include mental health and drugs and alcohol as part of their comprehensive approach to HIV prevention. A majority of participants (72%) owned a smart device. Smart device owners rated health issues similarly to those who did not, suggesting that such devices may be a useful platform to reach gay and bisexual men for health education and prevention.

Conflict and expectancies interact to predict sexual behavior under the influence among gay and bisexual men

As the mechanisms of the associations between substance use and risky sex remain unclear, this study investigates the interactive roles of conflicts about casual sex and condom use and expectancies of the sexual effects of substances in those associations among gay men. Conflict interacted with expectancies to predict sexual behavior under the influence; low casual sex conflict coupled with high expectancies predicted the highest number of casual partners, and high condom use conflict and high expectancies predicted the highest number of unprotected sex acts. Results have implications for intervention efforts that aim to improve sexual decision-making and reduce sexual expectancies.

Alcohol use predicts sexual risk behavior with HIV-negative or partners of unknown status among young HIV-positive men who have sex with men

Although the relationship between substance use and heightened sexual risk behaviors have been documented in samples of young men who have sex with men (YMSM) and HIV-positive adult men who have sex with men (MSM), there is a dearth of research on the role of substance use in the sexual risk behaviors of HIV-positive YMSM. We examined associations between alcohol and other drug use with sexual risk behaviors among a sample of HIV-positive YMSM (N=200). There were no significant predictors of either receptive or insertive unprotected anal intercourse (UAI) with HIV-positive partners among the substance use variables. Failure to use a condom after drinking alcohol (β=2.00, p<0.01) was significantly associated with insertive UAI with HIV-negative partners or partners of unknown status. Failure to use a condom after drinking alcohol (β=1.36, p<0.05) and age (β=0.35, p<0.05) were significantly associated with receptive UAI with HIV-negative partners or partners of unknown status. Findings from this article underscore the role of alcohol in facilitating UAI among HIV-positive YMSM and their HIV-negative and status-unknown partners.
