Sexual risk behaviors and substance use among alcohol abusing HIV-positive men who have sex with men

Integration of an Electronic Screening, Brief Intervention, and Referral to Treatment Program Into an HIV Testing Program to Reduce Substance Use and HIV Risk Behavior Among Men Who Have Sex With Men: Protocol for Intervention Development and a Pilot Randomized Controlled Trial

BACKGROUND

Men who have sex with men (MSM) are disproportionally affected by HIV and drug and alcohol use; however, few effective HIV prevention interventions for MSM who use substances exist. Screening, Brief Intervention, and Referral to Treatment is an early intervention for non-treatment-seeking individuals with problematic substance use and for timely referral to treatment for those with substance use disorders. Electronic screening and brief interventions (e-SBIs) reduce implementation challenges. An e-SBI tailored for MSM at the time of HIV testing might be particularly opportune to strengthen their motivation to reduce substance use and HIV risk behavior.

OBJECTIVE

This study aims to develop a tailored e-SBI program to reduce substance use and HIV risk behavior among MSM seeking HIV testing at Nexo Asociación Civil, our community partners in Argentina (primary); assess the feasibility and acceptability of integrating the e-SBI into the Nexo HIV testing program (primary); assess the feasibility and acceptability of implementing an adapted Men's Health Project (MHP) at Nexo (secondary); and finally, explore preliminary findings on substance use and sexual risk reduction outcomes (exploratory).

METHODS

This mixed methods study has 2 stages. During stage 1 (development), we will use the User Centered Rapid App Design process consisting of focus groups (n=16), individual interviews (n=24), and a pilot deployment of the e-SBI (n=50) to iteratively develop the e-SBI. Quantitative and qualitative assessments at each step will inform the revision of the e-SBI. Furthermore, we will use the assessment, decision, administration, production, topic experts, integration, training, testing framework to adapt MHP. During stage 2 (pilot randomized controlled trial [RCT]), we will randomize 200 MSM coming to Nexo for HIV testing. They will complete a baseline assessment and then their assigned intervention (e-SBI vs screening only) and will be followed-up for 6 months. We will also conduct in-depth interviews with up to 45 participants: 15 participants from either study condition who entered or completed MHP or other substance abuse treatment and 15 from each arm who met the criteria for MHP but did not request it.

RESULTS

The study began recruitment in October 2022, and the stage-1 pilot study is near completion. Preliminary findings from stage 1 show high e-SBI acceptability. Data analysis of the stage-1 pilot is now beginning. The stage-2 pilot RCT will be launched in March 2024, with all data collection completed by May 2025.

CONCLUSIONS

This study will allow us to assess the acceptability and feasibility of e-SBI implementation during HIV testing encounters. We will also build the necessary research infrastructure for a subsequent RCT to assess the efficacy of e-SBIs in reducing substance use and HIV sexual risk behavior among MSM in this setting.

Assessment of a Daily Diary Study Including Biospecimen Collections in a Sample of Sexual and Gender Minority Young Adults: Feasibility and Acceptability Study

BACKGROUND

Young sexual minority men (YSMM) engage in cardiometabolic risk behaviors (eg, substance use) at higher rates than their heterosexual counterparts. Theory and previous research suggest that these risk behaviors may stem, in part, from exposure to minority stress (ie, discrimination based on sexual identity and other identities such as race).

OBJECTIVE

This pilot study examined the feasibility and acceptability of a virtual 2-day daily diary study that examined daily experiences with discrimination, cardiometabolic risk behaviors (ie, sleep, physical activity, and substance use behaviors), and patterns of physiological stress and inflammation among YSMM aged 18 to 35 years.

METHODS

Participants (n=20) were recruited from the greater New York metropolitan area and engaged in a 2-day daily diary protocol wherein they provided web-based consent, took a web-based baseline survey, and then, starting the next day, provided 3 saliva samples a day for 2 consecutive days to measure salivary cortisol, engaged in 3 daily diaries per day, and provided 1 blood spot sample via the finger prick method to measure high-sensitivity C-reactive protein. At follow-up, participants were interviewed via videoconferencing to ascertain their experiences and feelings related to the study protocol. Qualitative analyses explored the feasibility and acceptability of the study protocol, and exploratory quantitative analyses explored the descriptive statistics and Pearson correlations among the main study variables of interest.

RESULTS

The retention rate was high (19/20, 95%) in our study sample. Qualitative analyses demonstrated that participants were willing to engage in similar, longer-term studies (eg, studies that include both week and weekend days) in the future and suggested the feasibility and acceptability of our study protocol among YSMM. However, participants noted several areas for improvement (eg, redundancy of survey items and difficulty pricking one's finger) that should be considered in future research. Preliminary quantitative analyses revealed a moderate negative correlation between everyday discrimination and mean cortisol levels (r=-0.51; P=.03). Furthermore, descriptive analyses suggest that that daily cortisol curves differ across races or ethnicities among YSMM. White and other-identified YSMM experienced the highest cortisol awakening response (mean 0.39, SD 0.21 µg/dL for White participants; mean 0.34, SD 0.34 µg/dL for others) with the steepest decline around bedtime (mean 0.05, SD 0.04 µg/dL for White participants; mean 0.09, SD 0.13 µg/dL for others) followed by a lower cortisol awakening response (mean 0.31, SD 0.11 µg/dL for Hispanic participants; mean 0.23, SD 0.15 µg/dL for Black participants) and a slower decline around bedtime (mean 0.10, SD 0.09 µg/dL for Hispanic participants; mean 0.03, SD 0.02 µg/dL for Black participants) among Hispanic and Black YSMM.

CONCLUSIONS

Overall, the results suggest that similar study protocols are feasible and acceptable among YSMM. Future research should highlight the pathways through which cardiovascular disease risk may arise among YSMM using longer-term study designs and more diverse study samples.

Substance Use and Healthcare Utilization Across the Pre-Exposure Prophylaxis (PrEP) Care Cascade among Black and Latino Men Who Have Sex with Men

Background: Despite the documented efficacy of pre-exposure prophylaxis (PrEP) for HIV prevention, large disparities in uptake and adherence exist among Black and Latino/Hispanic men who have sex with men (BLMSM). Limited data exists among BLMSM on the impact of substance use at different stages of the PrEP Care Cascade. We examined the ways substance (alcohol, cannabis, other drug) use is related to PrEP experiences across the PrEP Care Cascade (PrEP aware/no use; PrEP use/discontinuation; PrEP use/adherent).Methods: We utilized data from a national sample of 908 BLMSM (Mage = 25.17, range: 18-29), collected between February and October 2020.Results: We found that heavier alcohol use, more other drug (e.g., cocaine) use, more participant healthcare utilization, and higher number of partners across all measures of substance use were separately associated with a lower likelihood of being aware of PrEP. These same factors were also associated with a higher likelihood of PrEP adherence. Conversely, only cannabis use was associated with discontinuation of PrEP use.Conclusions: While we confirm some earlier findings (i.e., alcohol use is associated with both PrEP discontinuation and PrEP use), we newly identify cannabis as a barrier to the adherence of PrEP. Our findings highlight the need for improved PrEP interventions to increase awareness among BLMSM with substance use who are among the most at-risk for HIV infection.

Cannabis and Alcohol Co-Use and Condomless Anal Sex Among Men Who have Sex with Men Living with HIV: An Event-Level Analysis

Men who have sex with men (MSM) account for more than two thirds of new HIV diagnoses annually. Sexual behavior that increases risk for onward transmission of HIV is associated with both alcohol and cannabis use. However, little is known about the influence of cannabis and alcohol co-use on engagement in condomless anal sex (CAS). The current study explored daily associations between substance use and CAS among HIV-positive MSM using a 42-day timeline followback interview (N = 101). Generalized estimating equation (GEE) logistic regression models were used to examine the association between cannabis and alcohol co-use and CAS at the sexual event while controlling for study site, condition, adherence to antiretroviral therapy, sex-related alcohol expectancies, and partner type. Participants provided data for 1052 sexual activity days, 60.7% of which involved CAS. Of 638 CAS days, 9.1% involved no substances, 72.0% involved either cannabis or alcohol use, and 18.9% involved cannabis and alcohol co-use. Results indicated that the odds of engaging in CAS were higher for sexual events in which cannabis and alcohol co-use occurred (aOR 2.98; 95% CI 1.27, 6.97) compared to events in which no substance use occurred (p = 0.012), but this relationship was no longer significant when cannabis and alcohol co-use was compared to single substance use (aOR 1.57; 95% CI 0.85, 2.90; p = 0.15). Future research should identify specific substance use (e.g., quantity) and partner characteristics (e.g., level of intoxication) that may uniquely influence the relationship between cannabis and alcohol co-use and condomless sex.

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

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

Clinic-Based Delivery of the Young Men's Health Project (YMHP) Targeting HIV Risk Reduction and Substance Use Among Young Men Who Have Sex with Men: Protocol for a Type 2, Hybrid Implementation-Effectiveness Trial

BACKGROUND

Young men who have sex with men (YMSM) are disproportionately at risk for HIV and sexually transmitted infections. Adapting and testing the effectiveness of the Young Men's Health Project (YMHP), an efficacious intervention designed to reduce substance use and condomless anal sex (CAS) among YMSM, at clinics in Miami, Detroit, and Philadelphia has the potential to reduce HIV and STI disparities among urban YMSM.

OBJECTIVE

This study (Adolescent Medicine Trials Network for HIV/AIDS Interventions [ATN] 145 YMHP) aims to adapt YMHP for clinic and remote delivery by existing clinic staff and compare their effectiveness in real-world adolescent HIV clinics. This protocol is part of the ATN Scale It Up program described in a recently published article by Naar et al.

METHODS

This is a comparative effectiveness hybrid type-2 trial of the YMHP intervention with 2 delivery formats-clinic-based versus remote delivery-offered following HIV counseling and testing. Phase 1 includes conducting focus groups with youth to obtain implementation feedback about the delivery of the YMHP intervention and intervention components to ensure culturally competent, feasible, and scalable implementation. Phase 2 includes recruitment and enrollment of 270 YMSM, aged 15 to 24 years, 90 at each of the 3 sites. Enrollment will be limited to HIV-negative YMSM who report recent substance use and either CAS or a positive STI test result. Participants will be randomized to receive the YMHP intervention either in person or by remote delivery. Both conditions involve completion of the 4 YMHP sessions and the delivery of pre-exposure prophylaxis information and navigation services. A minimum of 2 community health workers (CHWs) will be trained to deliver the intervention sessions at each site. Sessions will be audio-recorded for Motivational Interviewing Treatment Integrity (MITI) fidelity coding, and CHWs and supervisors will be given implementation support throughout the study period.

RESULTS

Phase 1 focus groups were completed in July 2017 (n=25). Feedback from these focus groups at the 3 sites informed adaptations to the YMHP intervention manual, implementation of the intervention, and recruitment plans for phase 2. Baseline enrollment for phase 2 began in November 2018, and assessments will be at immediate posttest (IP)-, 3-, 6-, 9-, and 12-months after the intervention. Upon collection of both baseline and follow-up data, we will compare the effectiveness and cost-effectiveness of clinic-based versus remote delivery of YMHP in the context of health care access.

CONCLUSIONS

We are conducting YMHP in 3 cities with high rates of YMSM at risk for HIV and STIs. When adapted for real-world clinics, this study will help substance-using YMSM at risk for HIV and STIs and allow us to examine differences in effectiveness and cost by the method of delivery.

An mHealth Intervention to Improve Young Gay and Bisexual Men's Sexual, Behavioral, and Mental Health in a Structurally Stigmatizing National Context

BACKGROUND

Young gay and bisexual men (YGBM) in some Eastern European countries, such as Romania, face high stigma and discrimination, including in health care. Increasing HIV transmission is a concern given inadequate prevention, travel to high-prevalence countries, and popularity of sexual networking technologies.

OBJECTIVE

This study aimed to adapt and pilot test, in Romania, a preliminarily efficacious mobile health (mHealth) HIV-prevention intervention, created in the United States, to reduce HIV risk among YGBM.

METHODS

After an intervention formative phase, we enrolled 43 YGBM, mean age 23.2 (SD 3.6) years, who reported condomless sex with a male partner and at least 5 days of heavy drinking in the past 3 months. These YGBM completed up to eight 60-minute text-based counseling sessions grounded in motivational interviewing and cognitive behavioral skills training with trained counselors on a private study mobile platform. We conducted one-group pre-post intervention assessments of sexual (eg, HIV-risk behavior), behavioral (eg, alcohol use), and mental health (eg, depression) outcomes to evaluate the intervention impact.

RESULTS

From baseline to follow-up, participants reported significant (1) increases in HIV-related knowledge (mean 4.6 vs mean 4.8; P=.001) and recent HIV testing (mean 2.8 vs mean 3.3; P=.05); (2) reductions in the number of days of heavy alcohol consumption (mean 12.8 vs mean 6.9; P=.005), and (3) increases in the self-efficacy of condom use (mean 3.3 vs mean 4.0; P=.01). Participants reported significant reductions in anxiety (mean 1.4 vs mean 1.0; P=.02) and depression (mean 1.5 vs mean 1.0; P=.003). The intervention yielded high acceptability and feasibility: 86% (38/44) of participants who began the intervention completed the minimum dose of 5 sessions, with an average of 7.1 sessions completed; evaluation interviews indicated that participation was rewarding and an "eye-opener" about HIV risk reduction, healthy identity development, and partner communication.

CONCLUSIONS

This first mHealth HIV risk-reduction pilot intervention for YGBM in Eastern Europe indicates preliminary efficacy and strong acceptability and feasibility. This mobile prevention tool lends itself to broad dissemination across various similar settings pending future efficacy testing in a large trial, especially in contexts where stigma keeps YGBM out of reach of affirmative health interventions.

Relationship between serostatus disclosure and categories of HIV transmission risk in men who have sex with men living with HIV

In prior studies, the relationship between serostatus disclosure and reduced HIV transmission risk has been mixed. The demonstration of a clear connection may be restricted by three main methodological limitations. This study evaluates the relationship between (1) more refined measures of serostatus disclosure and (2) eight categories of HIV transmission risk (lowest to highest risk) among men who have sex with men (MSM) living with HIV, while (3) considering a number of control variables. Results demonstrate that disclosure is more likely in sexual encounters involving no intercourse or involving protected and unprotected anal intercourse with HIV-positive partners than unprotected insertive anal intercourse with HIV-negative/unknown status partners. Additionally, substance use prior to sexual encounters is less likely in lower risk categories than the highest risk category. Results of this study are important to the design of future studies, prevention, and intervention programs for MSM and to the methods used to evaluate their effectiveness.

Behavioral Interventions Targeting Alcohol Use Among People Living with HIV/AIDS: A Systematic Review and Meta-Analysis

Alcohol use is often reported among people living with HIV/AIDS (PLWHA) and is associated with increased sexual risk and poor medication adherence. This meta-analysis evaluated the efficacy of behavioral interventions addressing alcohol use among PLWHA. Twenty-one studies (N = 8461 PLWHA) that evaluated an individual-level intervention addressing alcohol use alone or as part of a more comprehensive alcohol/HIV intervention, included a control condition, and were available through December 2016 were included. Independent raters coded study, sample, and intervention content. Weighted mean effect sizes, using random-effects models, were calculated. Results indicate that interventions reduced alcohol consumption, increased condom use, and improved medication adherence relative to controls (d +s = 0.10-0.24). Plasma viral load was also reduced in intervention versus control participants (d + = 0.14, 95% CI = 0.02, 0.26; k = 7). These findings show that behavioral interventions addressing alcohol use can successfully reduce alcohol consumption and also improve HIV-related outcomes among PLWHA.

HIV-1 Proteins Influence Novelty-Seeking Behavior and Alter Region-Specific Transcriptional Responses to Chronic Nicotine Treatment in HIV-1Tg Rats

INTRODUCTION

Clinical studies suggest that HIV-1-infected patients are more likely to use or abuse addictive drugs than is the general population. We hypothesized that HIV-1 proteins impact novelty-seeking behavior and enhance the transcriptional response to nicotine in genes implicated in both novelty-seeking behavior and drug addiction.

METHODS

We assessed the effects of HIV-1 proteins on novelty-seeking behavior by comparing baseline activity differences of HIV-1Tg and F344 control rats in the open-field test. One day after behavioral testing, all rats began daily subcutaneous injections of either nicotine (0.4 mg/kg, base) or saline (the same for each rat) for 27 days. At the end of treatment, the prefrontal cortex, nucleus accumbens, and ventral tegmental area were collected for RNA expression analysis of genes in the receptor families for dopamine, GABA, glutamate, and serotonin.

RESULTS

Significant strain difference was detected in the distance moved in the center, such that HIV-1Tg rats traveled greater distance in the center of the arena than did F344 rats. Quantitative RT-PCR analysis showed that mRNA from Drd3 and Grm2 in the prefrontal cortex and Drd5 and Gabra6 in the ventral tegmental area was significantly upregulated, whereas that of Drd5 in the nucleus accumbens was downregulated in HIV-1Tg rats compared with F344 rats. Further, more addiction-related genes were significantly modulated by nicotine in each brain region in the HIV-1Tg rats than in the control animals.

CONCLUSIONS

HIV-1 proteins may affect novelty-seeking behavior and modulate the expression of genes related to drug addiction and novelty-seeking behavior.

IMPLICATIONS

HIV-1 viral proteins and chronic nicotine treatment impact the expression of genes involved in novelty-seeking behavior and addiction in three brain regions of the HIV-1 transgenic rat. These findings implicate that HIV-1 proteins may be involved in novelty-seeking behavior and in modulating the expression of genes related to drug addiction and novelty seeking.

Outcomes from a Homegrown HIV Prevention Program for Extremely High-risk, Substance-using Men who have Sex with Men with Multiple Health Disparities

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.

Demographic Predictors of Event-Level Associations between Alcohol Consumption and Sexual Behavior

Alcohol consumption is associated with sexual behavior and outcomes, though research indicates a variety of moderating factors, including demographic characteristics. To better target interventions aimed at alcohol-related sexual risk behavior, our analyses simultaneously examine demographic predictors of both day- and event-level associations between alcohol consumption and sexual behavior in a sample of young adults (N = 301) who are sexually active and consume alcohol. Young adults (aged 18-29) recruited using time-space sampling and incentivized snowball sampling completed a survey and a timeline follow-back calendar reporting alcohol consumption and sexual behavior in the past 30 days. On a given day, a greater number of drinks consumed was associated with higher likelihood of sex occurring, particularly for women and single participants. During a given sexual event, number of drinks consumed was not associated with condom use, nor did any demographic predictors predict that association. Findings highlight associations between alcohol and sexual behavior, though not between alcohol and sexual risk behavior, highlighting the need for additional research exploring the complex role of alcohol in sexual risk behavior and the need to develop prevention efforts to minimize the role of alcohol in the initiation of sexual encounters.

Prevalence of Psychiatric and Substance Abuse Symptomatology Among HIV-Infected Gay and Bisexual Men in HIV Primary Care

BACKGROUND

The presence of psychiatric symptoms in gay/bisexual men managing HIV are underidentified and undertreated and can interfere with optimal HIV disease management. There is a paucity of prevalence reports of these symptoms in this group, identified in the primary HIV care setting. Few studies have compared prevalence rates based on empirically supported screening tools in relation to diagnoses made in primary care.

OBJECTIVE

The purpose of this study was to identify the prevalence of psychiatric symptoms and substance abuse in HIV-infected gay/bisexual men and to estimate the proportion of those who had been diagnosed within their primary medical care setting.

METHOD

Participants (n = 503) were HIV-infected gay/bisexual men screened for participation in a HIV prevention trial and completed psychosocial assessment. Data were also extracted from patients׳ electronic medical record.

RESULTS

More than 47% of participants met diagnostic screen-in criteria for any anxiety disorder, of whom approximately one-third were identified in primary care. More than 22% screened in for a depressive mood disorder, approximately 50% of whom had been identified in primary care. A quarter of the sample had elevated substance abuse symptoms, 19.4% of whom were identified in primary care. Of those with symptoms of alcohol abuse (19.9%), 9.0% of those were identified in primary care.

CONCLUSION

These results provide some evidence suggesting that mood, anxiety, and substance abuse symptomatology are prevalent among HIV-infected gay/bisexual men and are underidentified in primary care. Increased mental health and substance use screening integrated into HIV primary care treatment settings may help to identify more gay/bisexual men in need of treatment.

Feasibility, Acceptability, and Preliminary Efficacy of a Live-Chat Social Media Intervention to Reduce HIV Risk Among Young Men Who Have Sex With Men

Given the popularity of social media among young men who have sex with men (YMSM), and in light of YMSM's elevated and increasing HIV rates, we tested the feasibility, acceptability and preliminary efficacy of a live chat intervention delivered on Facebook in reducing condomless anal sex and substance use within a group of high risk YMSM in a pre-post design with no control group. Participants (N = 41; 18-29 years old) completed up to eight one-hour motivational interviewing and cognitive behavioral skills-based online live chat intervention sessions, and reported on demographic, psychosocial, and behavioral characteristics at baseline and immediately post-intervention. Analyses indicated that participation in the intervention (n = 31) was associated with reductions of days of drug and alcohol use in the past month and instances of anal sex without a condom (including under the influence of substances), as well as increases in knowledge of HIV-related risks at 3-month follow-up. This pilot study argues for the potential of this social media-delivered intervention to reduce HIV risk among a most vulnerable group in the United States, in a manner that was highly acceptable to receive and feasible to execute. A future randomized controlled trial could generate an intervention blueprint for providers to support YMSM's wellbeing by reaching them regardless of their geographical location, at a low cost.

Comparing Psychosocial Correlates of Condomless Anal Sex in HIV-Diagnosed and HIV-Nondiagnosed Men Who Have Sex with Men: A Series of Meta-Analyses of Studies from 1993-2013

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.

Drinking trajectories among HIV-infected men who have sex with men: a cohort study of United States veterans

BACKGROUND

Although high rates of alcohol consumption and related problems have been observed among HIV-infected men who have sex with men (MSM), little is known about the long-term patterns of and factors associated with hazardous alcohol use in this population. We sought to identify alcohol use trajectories and correlates of hazardous alcohol use among HIV-infected MSM.

METHODS

Sexually active, HIV-infected MSM participating in the Veterans Aging Cohort Study were eligible for inclusion. Participants were recruited from VA infectious disease clinics in Atlanta, Baltimore, New York, Houston, Los Angeles, Pittsburgh, and Washington, DC. Data from annual self-reported assessments and group-based trajectory models were used to identify distinct alcohol use trajectories over an eight-year study period (2002-2010). We then used generalized estimate equations (GEE) to examine longitudinal correlates of hazardous alcohol use (defined as an AUDIT-C score ≥4).

RESULTS

Among 1065 participants, the mean age was 45.5 (SD=9.2) and 606 (58.2%) were African American. Baseline hazardous alcohol use was reported by 309 (29.3%). Group-based trajectory modeling revealed a distinct group (12.5% of the sample) with consistently hazardous alcohol use, characterized by a mean AUDIT-C score of >5 at every time point. In a GEE-based multivariable model, hazardous alcohol use was associated with earning <$6000 annually, having an alcohol-related diagnosis, using cannabis, and using cocaine.

CONCLUSIONS

More than 1 in 10 HIV-infected MSM US veterans reported consistent, long-term hazardous alcohol use. Financial insecurity and concurrent substance use were predictors of consistently hazardous alcohol use, and may be modifiable targets for intervention.

Unprotected sexual practices among men who have sex with women and men who have sex with men living with HIV/AIDS in Rio de Janeiro

Combined antiretroviral therapy is now acknowledged for preventing new HIV infections, besides decreasing mortality and morbidity. However, in many Latin America countries the epidemic is still driven by unprotected sexual intercourse. This study aims to describe sexual practices related to HIV/STD and to evaluate factors associated to unprotected sex among men who have sex with women (MSW) and men who have sex with men (MSM) under care at a reference center for HIV in Rio de Janeiro, Brazil. A cross-sectional study, nested in a Brazilian clinical cohort, evaluated the sexual practices of 404 sexually active HIV-positive MSW and men who have MSM. Approximately 30 % of them reported unprotected sexual practices during the 6 months prior to the interview. Most frequent risky practices reported were unprotected vaginal sex among MSW and unprotected receptive anal sex among MSM. Factors increasing the chance of unprotected sexual practices among MSW were the partner's desire of becoming pregnant (OR 2.81; CI 95 %: 1.36-5.95). To have received comments about excessive consumption of alcohol (OR 2.43; CI 95 %: 1.01-5.83), illicit drug use (OR 4.41; CI 95 %: 1.75-11.60) and lived in marital situation (OR 2.10; CI 95 %: 1.09-4.08) were significantly associated with unsafe sexual practices among MSM. The results highlight that health care of men living with HIV, as well as the prevention strategies, must consider the particularities of sexual behavior practiced by people who differ in sexual orientation.

An examination of associations between social norms and risky alcohol use among African American men who have sex with men

BACKGROUND

Research has indicated associations between risky alcohol consumption and sexual risk behavior, which may in turn present risk of HIV acquisition or transmission. Little is known about social determinants of problematic alcohol use among African American MSM (AA MSM), a risk group disproportionately affected by HIV. The present study sought to explore associations between risky alcohol use and perceived peer norms of alcohol use among a sample of urban African American men who have sex with men (AA MSM).

METHODS

A cross-sectional survey was administered to 142 AA MSM in Baltimore, Maryland, recruited using active and passive methods. Risky and hazardous alcohol use was assessed using the Alcohol Use Disorders Identification Test (AUDIT) and participants self-reported descriptive and injunctive peer norms regarding frequency and quantity of alcohol consumption.

RESULTS

Nearly half reported hazardous or high risk consumption of alcohol. Perceived peer alcohol norms, both descriptive and injunctive, were associated with alcohol use, including hazardous use.

CONCLUSIONS

The findings highlight the role of social factors on problematic alcohol use among AA MSM. Results indicate that AA MSM's use of alcohol is associated with their perceptions of peer alcohol use. Potential interventions could include norms-based campaigns that seek to reduce risky alcohol consumption among AA MSM as well as programs to screen and identify individuals with problematic alcohol use.

An examination of places where African American men who have sex with men (MSM) use drugs/drink alcohol: a focus on social and spatial characteristics

BACKGROUND

Drug and alcohol use are risk factors for HIV transmission. Much of the HIV behavioural research has focused on risk without consideration of the social and spatial context of the behaviour. Yet, risk may be specific or unique to place. The purpose of this study was to examine the social and spatial characteristics of places where African American men who have sex with men (AA MSM) use drugs and/or alcohol. Specifically, we examined spatial intensity and clustering of drug/alcohol places and characteristics of their social networks at these places.

METHODS

Participants were recruited using outreach, on-line advertisements and word-of-mouth referrals. Inclusion criteria were: age 18 or older and sex with a man in the prior 90 days. Participants (n=51) completed a socio-spatial inventory in which they provided addresses of n=187 places where they most recently used drugs and/or drank alcohol. Participants described characteristics of people who were at these places.

RESULTS

The mean age of participants was 36.5 years (SD=10.9). Half (51%) identified as gay, 31% bisexual, 4% heterosexual and 10% as not sure/questioning and 27% self-reported HIV positive status. Drug/alcohol places were spatially concentrated in the inner part of the city and evidence of clustering by participant characteristics was present. Of n=187 places named where the participant drank alcohol or used drugs, 68% were described as a residence (participants or "someone one else's house"), 20% were bars/clubs or restaurants, 8% were outside places and 4% were miscellaneous (e.g. on the bus/car). There were differences in the characteristics of social network members by place-type. At residential places, a greater proportion of networks listed were sex partners or kin, compared to other place-types. A greater proportion of networks listed at bars/clubs/restaurants were gay, knew that the participant had sex with men, and were younger compared to other place-types.

CONCLUSION

AA MSM drink alcohol and use drugs in a variety of place-types and with various social network members. Little research has been done on factors that shape the geography of AA MSM substance use. Future research is needed to explore these complex associations.

Prevalence of syphilis infection and associations with sexual risk behaviours among HIV-positive men who have sex with men in Shanghai, China

The aims of this study were to understand the prevalence and correlates of syphilis infection among HIV-positive men who have sex with men (MSM) in Shanghai, China. A total of 200 HIV-positive MSM participants were recruited using “snowball” sampling. Participants were tested for syphilis and completed a one-time questionnaire which included demographic characteristics, sexual behaviours with male and female sexual partners, substance use, and use of antiretroviral medications. Prevalence of syphilis infection was 16.5%. Among HIV/syphilis co-infected participants, 63.6% reported having anal sex with male partners and 24.2% did not use condoms consistently during the past six months; 66.7% reported having oral sex with male partners and 51.5% reported unprotected oral sex during the past six months. Factors associated with testing seropositive for syphilis infection included receptive anal sex with a male partner in the past six months (AOR = 12.61, 90% CI = 2.38–66.89), illicit drug use in the past six months (AOR = 11.47, 90% CI = 2.47–53.45), and use of antiretroviral medication (AOR = 4.48, 90% CI = 1.43–14.05). These data indicate a need for “positive prevention” interventions targeting HIV-positive MSM in China.

Attitudes toward methamphetamine use and HIV risk behavior in men who have sex with men

BACKGROUND AND OBJECTIVES

Methamphetamine use has been strongly associated with high-risk sexual behaviors, and its use has been increasing among men who have sex with men (MSM). Although the behavioral implications of methamphetamine use and sexual risk have been broadly examined, fewer studies have examined attitudes about methamphetamine use.

METHODS

This study investigates the relationship between personal beliefs regarding methamphetamine use, patterns of use, and sexual risk behaviors within a sample of MSM attending a gay pride event (N= 342).

RESULTS

A minority of MSM reported lifetime (27%) or recent (7%) methamphetamine use. Only a minority of MSM who had used methamphetamine believed that it enhanced sexual pleasure (32%) or incorporated methamphetamine use into their sexual activity (31%). Individuals who used methamphetamine during sexual activity were more likely to be recent users of the drug and more likely to engage in high-risk behaviors. A significant minority of participants endorsed items assessing the disinhibiting effects of methamphetamine including being less likely to use a condom (35%) and less selective in their choice of partners (26%).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Results suggest that prevention efforts may benefit from targeting the minority of methamphetamine users who perceive methamphetamine as enhancing sexual activity and use it for this purpose.

Predictors of day-level sexual risk for young gay and bisexual men

As HIV infection rates remain high among young gay and bisexual men, investigations into determinants of sexual risk are paramount. This study examined independent and interactive effects of substance use, mental health, perceived benefits of unprotected sex, and type of sex partner on odds of not using condoms. Analyses included 188 high-risk substance using HIV-negative and unknown status young gay and bisexual men (ages 18-29). Substance use and endorsing favorable attitudes towards unprotected sex strongly predicted sexual risk. Mental health moderated the relationship between partner type (main vs. casual) and condom use such that increased anxiety and depression were associated with increased odds of using condoms with main partners and not using condoms with casual partners. Understanding how these determinants of HIV risk converge to predict unprotected anal sex can identify essential risk relationships for prevention, obtain effects sizes of greater magnitude and prolonged sustainability, and build robust couples-based interventions.

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.

Sexuality and risk behavior among men who have sex with men in León, Nicaragua: a mixed methods approach

INTRODUCTION

HIV prevalence among men who have sex with men (MSM) is 38 times higher than among the general population in Nicaragua. There are little data about the sexuality and sexual behaviors of MSM. It is essential to gain a better understanding of this understudied population.

AIMS

The nature of sexual relationships among MSM, their reasons for engaging in risky sexual behaviors, and the sociocultural context in León, Nicaragua, were investigated through in-depth interviews. Our findings resulted in a structured overview of sociodemographic characteristics and HIV-related knowledge, attitudes, and risk behaviors.

METHODS

Fifteen participants recruited by purposive sampling completed an in-depth interview that was then thematically analyzed. An additional 104 participants were surveyed by means of an interviewer-administered questionnaire.

MAIN OUTCOME MEASURES

The in-depth interview guide and the survey covered topics related to sociodemographics, childhood, social and sexual relationships, knowledge and attitudes toward HIV and AIDS, identity, and networks.

RESULTS

The resulting ecological model explored sexuality and behaviors in four categories. It showed that despite a homophobic and heterosexist society, there is an increasing gay community and greater social acceptance of homosexuality. Nevertheless, interpersonal and intrapersonal factors continue to negatively influence MSM behavior. Quantitative findings demonstrate a satisfactory understanding of HIV transmission among this population, 75% of whom reported concerns of becoming infected with HIV in the future. Approximately one-half claimed that they always used condoms when having sex with men, but only one-third of the time with women, indicating inconsistent condom use. Negative attitudes toward HIV/AIDS were seldom heard.

CONCLUSIONS

This study is the first mixed methods approach in a Nicaraguan context that shows the interrelations among sex, sexuality, and identity at various levels of MSM life, and how they influence the sexual risk behaviors of individuals. Engaging in unprotected sex and postponing HIV testing are seen as cognitive dissonances.

Patterns of substance use among a large urban cohort of HIV-infected men who have sex with men in primary care

The present study sought to identify characteristics of HIV-infected MSM that are associated with the use of specific substances and substance abuse in general. Participants were 503 HIV-infected MSM who were receiving primary care. A self-assessment and medical records were used to obtain information about past 3-month alcohol and drug use and abuse, and demographics, HIV-disease stage and treatment, sexual risk, and mental health. Associations of these four domains with substance use and abuse outcomes were examined using hierarchical block-stepwise multivariable logistic regression. Substance use and abuse in the sample was high. Transmission risk behavior was significantly associated with over half of the outcomes. The associations of demographic and HIV-disease stage and treatment variables varied by substance, and mental health problems contributed differentially to almost every outcome. These findings should be considered for designing, implementing, and evaluating substance use programming for HIV-infected MSM.

HIV intervention for providers study: a randomized controlled trial of a clinician-delivered HIV risk-reduction intervention for HIV-positive people

Clinician-delivered prevention interventions offer an opportunity to integrate risk-reduction counseling as a routine part of medical care. The HIV Intervention for Providers study, a randomized controlled trial, developed and tested a medical provider HIV prevention training intervention in 4 northern California HIV care clinics. Providers were assigned to either the intervention or control condition (usual care). The intervention arm received a 4-hour training on assessing sexual risk behavior with HIV-positive patients and delivering risk-reduction-oriented prevention messages to patients who reported risk behaviors with HIV-uninfected or unknown-status partners. To compare the efficacy of the intervention versus control on transmission risk behavior, 386 patients of the randomized providers were enrolled. Over six-months of follow-up, patients whose providers were assigned the intervention reported a relative increase in provider-patient discussions of safer sex (OR = 1.49; 95% CI = 1.06 to 2.09), assessment of sexual activity (OR = 1.60; 95% CI = 1.05 to 2.45), and a significant decrease in the number of sexual partners (OR = 0.49, 95% CI = 0.26 to 0.92). These findings show that a brief intervention to train HIV providers to identify risk and provide a prevention message results in increased prevention conversations and significantly reduced the mean number of sexual partners reported by HIV-positive patients.

USA study of sex toy use by HIV-positive men who have sex with other men: implications for sexual health

HIV/AIDS disproportionately impacts men who have sex with men (MSM) in the USA. Most existing literature on MSM with HIV focuses on transmission risk, but does not acknowledge health-promoting sexual behaviours men may undertake. This study examined sex toy use within this population to describe the extent to which using toys is incorporated into their sexual repertoires as a risk reduction practice. Data regarding sociodemographics, sexual/health-related behaviours and sex toy use were collected from 2275 MSM using an online survey. Most participants reported being sexually active (88.5%), and the majority (70.2%) of participants reported sex toy use within the previous year. Sex toy users were more likely to be white, in sexual relationships with others, and reported higher levels of sexual satisfaction. Given that sex toy use is common among this population, room for discussion exists about sex toys as tools to enhance pleasure and reduce HIV/sexually transmitted infection (STI) transmission.

Problematic alcohol use and HIV risk among Black men who have sex with men in Massachusetts

This analysis was designed to explore the frequency of problem drinking and its role in potentiating HIV risk among a community-recruited sample of Black men who have sex with men (MSM) in Massachusetts. Black MSM (n=197) recruited via modified respondent-driven sampling between January and July 2008 completed an interviewer-administered survey, including HIV sexual behavior, the Center for Epidemiologic Studies Depression Scale (CES-D), and the CAGE alcohol screener. Bivariate and multivariable logistic regression procedures examined the association of behavioral HIV-risk factors and other psychosocial variables with problematic alcohol use (CAGE score 3 or 4). Overall, 29% of the sample was found to abuse alcohol. In a multivariable model adjusting for demographic and behavioral variables, factors associated with increased odds of problem drinking were: (1) depressive symptoms (CES-D 16); (2) one or more episodes of serodiscordant unprotected anal sex during last sexual encounter with a casual male partner; and (3) one or more episodes of unprotected anal or vaginal sex with a female partner in the past 12 months. Black MSM who engaged in HIV risk behaviors may be more likely to have concurrent problematic alcohol use. HIV prevention interventions with Black MSM may benefit from incorporating screening and/or treatment for alcohol problems, as well as screening for co-morbid depressive symptoms.

The Treatment Advocacy Program: a randomized controlled trial of a peer-led safer sex intervention for HIV-infected men who have sex with men

OBJECTIVE

Primary care may be an effective venue for delivering behavioral interventions for sexual safety among HIV-positive men who have sex with men (MSM); however, few studies show efficacy for such an approach. We tested the efficacy of the Treatment Advocacy Program (TAP), a 4-session, primary-care-based, individual counseling intervention led by HIV-positive MSM "peer advocates" in reducing unprotected sex with HIV-negative or unknown partners (HIV transmission risk).

METHOD

We randomized 313 HIV-positive MSM to TAP or standard care. HIV transmission risk was assessed at baseline, 6 months, and 12 months (251 participants completed all study waves). We conducted intent-to-treat analyses using general estimating equations to test the interaction of group (TAP vs. standard care) by follow-up period.

RESULTS

At study completion, TAP participants reported greater transmission risk reduction than did those receiving standard care, χ2(2, N = 249) = 6.6, p = .04. Transmission risk among TAP participants decreased from 34% at baseline to about 20% at both 6 and 12 months: Transmission risk ranged from 23% to 25% among comparison participants.

CONCLUSIONS

TAP reduced transmission risk among HIV-positive MSM, although results are modest. Many participants and peer advocates commented favorably on the computer structure of the program. We feel that the key elements of TAP-computer-based and individually tailored session content, delivered by peers, in the primary care setting-warrant further exploration.

The Amyl Nitrite Expectancy Questionnaire for Men who have Sex with Men (AEQ-MSM): a measure of substance-related beliefs

A measure of perceived reinforcement associated with amyl nitrite was developed and evaluated among gay and bisexual men. This is the first known expectancy measure to date for this drug class. The Amyl Nitrite Expectancy Questionnaire for Men who have Sex with Men (AEQ-MSM) was completed online by 102 gay and bisexual men, between 2006 and 2008 in Queensland, Australia. The AEQ-MSM demonstrated good psychometric properties and was associated with consumption patterns. Factor analysis revealed three distinct reinforcement domains: "Enhanced sexual desire and pleasure," "Disorientation," and "Sexual negotiation." Limitations include sampling via self-selection, recruitment through health centers and self-report data. Implications for sexual activity and risk-taking, including reducing associated harm (e.g., HIV transmission), and future directions are discussed.

“It's a quick way to get what you want”: a formative exploration of HIV risk among urban Massachusetts men who have sex with men who attend sex parties

Community-based studies with men who have sex with men (MSM) suggest that between 8% and 25% of MSM have met recent male sexual partners at private sex parties. Little is known about HIV sexual risk behaviors of MSM who attend sex parties and whether risk reduction interventions can be delivered in this setting. In 2008, 40 MSM who reported attending and/or hosting sex parties in Massachusetts in the past 12 months completed a qualitative interview and quantitative assessment. Participants reported attending a mean number of 10 sex parties in Massachusetts in the past 12 months. A significant percentage (43%) reported also hosting sex parties. Participants had made sexual partner connections across multiple venues, including public cruising areas, bars/clubs, and the Internet. At the most recent sex party attended, the majority had used alcohol (58%) and/or drugs (50%), and one quarter (25%) put themselves at risk of acquiring or transmitting HIV or other sexually transmitted infections (STIs) by having unprotected anal sex with a mean number of three serodiscordant male sex partners. Although many participants perceived that communicating about sexual health in the sex party context would “ruin the mood,” the majority (80%) considered some form of HIV prevention at sex parties to be appropriate and necessary, as well as acceptable. Nonintrusive prevention and education activities were especially endorsed (i.e., condoms, lubricants, and coupons for free HIV/STI testing). The majority of participants (75%) expressed some interest in “safer sex” parties. MSM attending sex parties appear to be a subpopulation at high risk for HIV and STI acquisition and transmission. Risk reduction interventions responsive to the needs of MSM who attend sex parties are warranted.

The Drinking Expectancy Questionnaire for Men who have Sex with Men (DEQ-MSM): a measure of substance-related beliefs

INTRODUCTION AND AIMS

Alcohol expectancies are associated with drinking behaviour and post-drinking use thoughts, feelings and behaviours. The expectancies held by specific cultural or sub-cultural groups have rarely been investigated. This research maps expectancies specific to gay and other men who have sex with men (MSM) and their relationship with substance use. This study describes the specific development of a measure of such beliefs for alcohol, the Drinking Expectancy Questionnaire for Men who have Sex with Men (DEQ-MSM).

DESIGN AND METHODS

Items selected through a focus group and interviews were piloted on 220 self-identified gay or other MSM via an online questionnaire.

RESULTS

Factor analysis revealed three distinct substance reinforcement domains ('Cognitive impairment', 'Sexual activity' and 'Social and emotional facilitation'). These factors were associated with consumption patterns of alcohol, and in a crucial test of discriminant validity were not associated with the consumption of cannabis or stimulants. Similarities and differences with existing measures will also be discussed.

DISCUSSION AND CONCLUSIONS

The DEQ-MSM represents a reliable and valid measure of outcome expectancies, related to alcohol use among MSM, and represents an important advance as no known existing alcohol expectancy measure, to date, has been developed and/or normed for use among this group. Future applications of the DEQ-MSM in health promotion, clinical settings and research may contribute to reducing harm associated with alcohol use among MSM, including the development of alcohol use among young gay men.

The Cannabis Expectancy Questionnaire for Men who have Sex with Men (CEQ-MSM): A measure of substance-related beliefs

OBJECTIVE

Substance-related expectancies are associated with substance use and post-substance use thoughts, feelings and behaviours. The expectancies held by specific cultural or sub-cultural groups have rarely been investigated. This research maps expectancies specific to gay and other men who have sex with men (MSM) and their relationship with substance patterns and behaviours following use, including sexual practices (e.g., unprotected anal intercourse). This study describes the development of a measure of such beliefs for cannabis, the Cannabis Expectancy Questionnaire for Men who have Sex with Men (CEQ-MSM).

METHOD

Items selected through a focus group and interviews were piloted on 180 self-identified gay or other MSM via an online questionnaire.

RESULTS

Factor analysis revealed six distinct substance reinforcement domains ("Enhanced sexual experience", "Sexual negotiation", "Cognitive impairment", "Social and emotional facilitation", "Enhanced sexual desire", and "Sexual inhibition"). The scale was associated with consumption patterns of cannabis, and in a crucial test of discriminant validity not with the consumption of alcohol or stimulants.

CONCLUSIONS

The CEQ-MSM represents a reliable and valid measure of outcome expectancies, related to cannabis among MSM. Future applications of the CEQ-MSM in health promotion, clinical settings and research may contribute to reducing harm associated with substance use among MSM, including HIV transmission.

Comparison of substance use and risky sexual behavior among a diverse sample of urban, HIV-positive men who have sex with men

The purpose of this study was to examine substance use among a racially and ethnically diverse group of HIV-positive men who have sex with men (MSM) living in six U.S. cities, model associations between drug use and serodiscordant unprotected anal intercourse (SDUAI), and characterize users of the substances strongly associated with risky sexual behavior. Baseline questionnaire data from 675 participants of the Positive Connections intervention trial were analyzed. Overall, substance use was common; however, the highest percentage of stimulant (30%), methamphetamine (27%), and popper (i.e., amyl nitrite) (46%) use was reported among white MSM and crack/cocaine (38%) use was highest among African American MSM. Popper use versus non-use (odds ratio = 2.46; 95% confidence interval = 1.55-3.94) and condom self-efficacy (1 standard deviation (sd) increase on scale; odds ratio = .58; 95% confidence interval = .46-.73) were significantly associated with SDUAI after adjusting for key demographic and psychosocial factors. These results highlight the importance of addressing drug use in the context of sex for possible HIV transmission risk.

Predictors of condom use in a multisite study of high-risk youth living with HIV

Young people between the ages of 13 to 24 are at persistent risk for HIV infection in the United States (Centers for Disease Control and Prevention [CDC], 2006). Young adulthood is a period characterized by experimentation, including engagement in risky behaviors (e.g., substance use and sexual behavior) (Moore & Parsons, 2000). Most young adults are sexually active, with the highest rates of sexual activity reported among youth of color (Park, Mulye, Adams, Brindis, & Irwin, 2006). The prevalence of sexually transmitted infections (STIs), especially chlamydia and gonorrhea, peak in young adulthood and are highest among youth of color (CDC, 2003).

Alcohol use and risk of HIV infection among men who have sex with men

In the United States, men who have sex with men (MSM) currently represent more than 50% of those living with HIV and over 70% of HIV+ men (CDC 2007, http://www.cdc.gov/hiv/topics/msm/resources/factsheets/pdf/msm.pdf ). Male-to-male sexual contact has been identified as the predominant route of transmission among this sub-group, which underscores the need for research that targets risk factors associated with risky sex-related HIV acquisition. Along these lines, research has shown that one potentially important predictor variable for risky sex among MSM is alcohol use. The major aim of this paper is to review and integrate empirical evidence on the association of alcohol use and risky sex among MSM. A summary of the quantitative research is provided first, followed by a critique of the reviewed literature, a discussion of the consistency of the existing empirical evidence with predictions of current theories, and finally, recommendations for future research designed to evaluate alcohol-related sexual risk in MSM.

The consequences of substance use among gay and bisexual men: A Consensual Qualitative Research analysis

Background: Substance use is common among gay/bisexual men and is associated with significant health risks (e.g. HIV transmission). The consequences of substance use, across the range of substances commonly used, have received little attention. The purpose of this study is to map participant’s beliefs about the effects of substance use to inform prevention, health promotion and clinical interventions. Methods: Participants were interviewed about experiences regarding their substance use and recruited through medical and sexual health clinics. Data were collected though a consumer panel and individual interviews. Responses regarding perceived consequences of substance use were coded using Consensual Qualitative Research (CQR) methodology. Results: Most participants reported lifetime use of alcohol, cannabis, stimulants and amyl nitrite, and recent alcohol and cannabis use. A wide range of themes were identified regarding participant’s thoughts, emotions and behaviours (including sexual behaviours) secondary to substance use, including: cognitive functioning, mood, social interaction, physical effects, sexual activity, sexual risk-taking, perception of sexual experience, arousal, sensation, relaxation, disinhibition, energy/activity level and numbing. Analyses indicated several consequences were consistent across substance types (e.g. cognitive impairment, enhanced mood), whereas others were highly specific to a given substance (e.g. heightened arousal post amyl nitrite use). Conclusions: Prevention and interventions need to consider the variety of effects of substance use in tailoring effective education programs to reduce harms. A diversity of consequences appear to have direct and indirect impacts on decision-making, sexual activity and risk-taking. Findings lend support for the role of specific beliefs (e.g. expectancies) related to substance use on risk-related cognitions, emotions and behaviours.

HIV prevention altruism and sexual risk behavior in HIV-positive men who have sex with men

An understanding of men's motivations to avoid risk behavior is needed to create efficacious HIV prevention programs for HIV-positive men who have sex with men (MSM). This study investigates the relationship between sexual risk behavior and HIV prevention altruism, which is defined as the values, motivations, and practices of caretaking towards one's sexual partners to prevent the transmission of HIV. In a sample of 637 HIV-positive MSM, HIV prevention altruism significantly protects against serodiscordant unprotected anal intercourse (SDUAI) in crude analysis, but not after adjustment for drug use and compulsive sexual behavior. HIV prevention altruism is also related to not engaging in anal intercourse, but is not related to serodisclosure to secondary partners. Lack of altruism appears related to sexual risk behavior in HIV-positive MSM, although other psychological and contextual factors play significant roles. The promotion of HIV prevention altruism may provide a formidable new direction for HIV prevention programs.

Behavioral mediation of the relationship between psychosocial factors and HIV disease progression

The psychological and physical demands of coping with medication side effects and comorbid illnesses can be overwhelming and may influence behaviors, such as medication adherence, substance use, sexual risk behavior, and exercise that, in turn, affect health outcomes. Cross-sectional and prospective studies among diverse populations of persons living with HIV suggest that these behavioral mechanisms may be associated with HIV disease progression. The motivation to change behavior is often highest in the immediate aftermath of a stressor. However, over time the motivation to continue a particular behavior change is often challenged by habits, environmental influences, and psychosocial factors. Furthermore, a number of studies suggest that behavioral mechanisms may mediate the relationship between psychosocial variables (e.g., stress, depression, coping, and social support) and disease progression in HIV. Thus, developing clinical interventions that address these psychosocial factors and enhance protective health behaviors and reduce behaviors that convey risk to health are likely to lessen overall morbidity and mortality among patients living with HIV/AIDS.

Correlates of Substance Use in Relation to Sexual Behavior in Black Gay and Bisexual Men: Implications for HIV Prevention

Since the onset of the AIDS epidemic, Black gay and bisexual men have been at a substantial risk for acquiring HIV. Substance use has been identified as a significant risk factor for engaging in HIV sexual risk behavior. The purpose of this formative research investigation was to examine substance use in relation to sexual behavior through differentiating users versus nonusers of alcohol and recreational drugs before or during sex in a community-based sample of 481 Black gay and bisexual men in the New York metropolitan area. Binary logistic regression results demonstrated that alcohol use before or during sex was predictive of having a primary sex partner, casual sex partner, higher income, previous sexually transmitted infection testing, and a higher number of male sex partners. Recreational drug use before or during sex was predictive of having an HIV positive status, casual sex partner, unprotected anal intercourse with a male sex partner, and being younger. These findings present significant formative implications for the influence of substance use in relation to HIV sexual risk behavior in Black gay and bisexual men.

Predictors of frequent use of amphetamine type stimulants among HIV-negative gay men in Sydney, Australia

BACKGROUND

Rates of use of amphetamine type stimulants among gay men have raised questions about the role of these drugs in increases in HIV infections and risk behaviour, but the role risk behaviours play with regard to illicit drug use within this population has not been investigated.

METHOD

Health in men (HIM) is a cohort of 1427 HIV-negative men in Sydney, Australia. All participants undergo annual face-to-face interviews. We examined onset of use of methamphetamine and of ecstasy (MDMA) after their baseline interview.

RESULTS

Among baseline non-frequent users who completed an annual follow-up interview, 67 commenced at least weekly use of ecstasy, while 71 commenced at least weekly use of methamphetamine. Factors independently associated with commencing more frequent use of these drugs included being younger, greater involvement in gay social life, and having engaged in unprotected anal intercourse with casual partners.

CONCLUSIONS

The transition from non- or less-frequent drug use to more frequent drug use may be associated with changes in sexual behaviour. While it may be true that illicit drug use leads to unsafe sexual behaviour, it is equally true that illicit drugs are used to enhance sexual performance and pleasure. The relationship is bidirectional and complex and must be understood within the contexts of particular sexual sub-cultural practices: engaging in sexual risk behaviour may be an indicator of future drug use as much as the reverse.

Use of illicit drugs among gay men living with HIV in Sydney

BACKGROUND

Illicit drug use among gay men is common and is associated with behaviours that are at high risk for HIV transmission.

METHODS

We explored illicit drug use within an ongoing cohort study of gay men living with HIV in Sydney, Australia. Most (84.3%) of the 274 New South Wales participants interviewed in 2004 for the Positive Health Cohort of HIV-seropositive gay men had used illicit drugs in the 6 months before their baseline interview.

RESULTS

One in six men (17.8%) used 'party drugs' at least monthly. At 12 months' follow-up, in 2005, these patterns of illicit drug use were similar. Being younger, participating in gay 'party scenes' and engaging in 'esoteric sex practices' at baseline were associated with any and more frequent use of party drugs, both in 2004 and 2005. Illicit drug use was, however, not associated with condom use at the most recent sexual encounters.

DISCUSSION

Illicit drug use appears to be highly contextual among these gay men living with HIV, and the association with risk behaviour may reflect participation in sexually adventurous subcultures as much as a direct causal effect.

Unprotected anal intercourse and substance use among men who have sex with men with recent HIV infection

OBJECTIVES

To examine within-subjects and combined between- and within-subjects associations between substance use and unprotected anal intercourse (UAI) among men who have sex with men (MSM) with recent HIV infection.

METHODS

One hundred ninety-four MSM who were recently infected with HIV completed a computer-assisted questionnaire regarding sexual behaviors and substance use with their last 3 partners. Associations between UAI and substance use were assessed using conditional logistic regression (CLR) to assess associations among the 116 MSM reporting UAI with some but not all partners and generalized linear mixed effects models (GLMMs) to examine a combination of within- and between-subjects associations in the entire sample (N = 194).

RESULTS

In multivariate CLR models and GLMMs, UAI was associated with the use of methamphetamine (odds ratio [OR] = 4.9 and OR = 3.5, respectively), marijuana (OR = 4.0 and OR = 2.2, respectively) and erectile dysfunction medications (EDMs) when used with a main partner (OR = 13.8 and OR = 10.1, respectively).

CONCLUSIONS

Results indicate that a direct association may exist between specific substances and UAI and provide evidence that the use of methamphetamine and EDMs may contribute to HIV transmission.

Positive, negative, unknown: assumptions of HIV status among HIV-positive men who have sex with men

Serosorting (i.e., engaging in unprotected sex with partners known to be of the same serostatus) can be a difficult process for men who have sex with men (MSM) who frequently make assumptions about their partners' serostatus. This process can be further complicated by a partner's dishonesty as well as other individual and contextual factors. The present study specifically examined how assumptions of serostatus made about unknown serostatus partners impact on the sexual behavior of 110 alcohol-abusing HIV-positive MSM. Although previous research has shown that HIV-positive MSM are more likely to serosort with other known HIV-positive men than with known HIV-negative men, our data suggest that unprotected sex behavior may not be specifically driven by whether or not they made assumptions of seroconcordance or serodiscordance. The types of assumptions these HIV-positive MSM made about their unknown status sexual partners and the basis for such assumptions were also examined. Owing to the ambiguities involved in assumptions of a partner's serostatus in sexual encounters, the 'unknown status' partner category is analytically distinct from 'known status' categories, and needs to be more fully explored because of its impact on perceived serosorting, rather than actual serosorting, among HIV-positive men.
