Correlates of condom failure in a sexually active cohort of men who have sex with men

Condom Failure Among HIV-Negative Men in Serodiscordant Relationships in Australia, Brazil, and Thailand

Condoms continue to be used by many gay, bisexual, and other men who have sex with men (GBM) to reduce the risk of HIV transmission. However this is impacted by condom failure events, defined here as condom breakage and slippage. In a prospective, observational cohort study of 343 HIV serodiscordant male couples recruited through high HIV caseload clinics and hospitals between 2012 and 2016 in Australia, Brazil, and Thailand, condom failure rates and associated factors were analysed, including with the study partner versus other sexual partners. There were 717 reported instances of condom failure from an estimated total of 25,831 sex acts with condoms, from over 588.4 participant years of follow up. Of the HIV-negative partners (n = 343) in the study, more than a third (n = 117, 36.7%) reported at least one instance of condom failure with any partner type during study follow-up. Condom failure with their study partner was reported by 91/343 (26.5%) HIV-negative partners, compared with 43/343 (12.5%) who reported condom failure with other partners. In total, there were 86 events where the HIV-negative partner experienced ano-receptive condom failure with ejaculation, representing 12.0% of all failure events. In multivariable analysis, compared to Australia, HIV-negative men in Brazil reported a higher incidence risk rate of condom failure (IRR = 1.64, 95%CI 1.01-2.68, p = 0.046) and HIV-negative men who reported anal sex with other partners reported an increased risk of condom failure compared with men who only had sex with their study partner (IRR = 1.89, 95%CI 1.08-3.33, p = 0.025). Although at least one event of condom failure was reported by a significant proportion of participants, overall condom failure events represented a small proportion of the total condom protected sex acts.

Levels of clinical condom failure for anal sex: A randomized cross-over trial

BACKGROUND

Men who have sex with men (MSM) face a 28-fold higher risk of HIV acquisition than men who have sex with women (MSW). Condoms are the most accessible prevention method, with billions produced annually. Due to potentially high clinical failure, international regulatory agencies do not approve condoms for anal sex. This trial sought to provide data regarding approval of condoms for anal sex.

METHODS

We conducted a blinded, crossover randomized trial among MSM and MSW in Atlanta, Georgia, USA. Crossover conditions were standard condoms, thin condoms, and condoms fitted to each user's penile dimensions. The primary outcome was total clinical failure (slippage and/or breakage), assessed using an intention-to-treat analysis. A mixed methods model assessed differences in odds of failure. The study is registered with ClinicalTrials.gov, NCT02753842, and is completed.

FINDINGS

We enrolled 252 MSM and 252 MSW between May 19, 2016 and May 2, 2017. Participants reported a total of 4884 anal or vaginal sex acts using study-provided condoms. For all crossover conditions, clinical failure was lower for anal sex (0•7%, 16/2351) than for vaginal sex (1•9%, 48/2533), (odds ratio 0•40, 95% confidence interval 0•21, 0•75, p < •001)00. There was no difference in odds of failure for anal sex acts between the different types of condoms. Due to study design, nearly all anal sex acts used condom-compatible lubricant (98•3%), yet only a minority of vaginal sex acts (41•6%) used lubricant. Sex acts for which lubricant was used had lower failure for both anal and vaginal sex, with no difference in odds of failure between them.

INTERPRETATION

In the largest trial of effectiveness of condoms for anal sex to date, we found remarkably low levels of failure. Condoms should be approved by regulatory agencies for anal sex. Clinicians may recommend condoms as a highly efficacious HIV and STD prevention tool for anal sex. Differences between failure for anal and vaginal sex were likely due to differential use of lubricant. Condom promotion programs should consider providing additional lubricant for all condoms distributed.

Mood, Meth, Condom Use, and Gender: Latent Growth Curve Modeling Results from a Randomized Trial

Methamphetamine use poses increased risk for HIV and other sexually transmitted infections. There is robust evidence that methamphetamine use increases sexual risk behavior, like condomless sex, primarily among men who have sex with men but also among heterosexual women and men. Gender differences have been found among women and men who use meth, and there is a high degree of interconnectedness between meth use, depression, and condomless sex. The aims of the current study are to evaluate the efficacy of a theory-based, tri-focal intervention designed to reduce depression, meth use, and condomless sex among women and men, and to examine gender as a moderator of efficacy. A total of 432 HIV-negative women and men who use meth participated in a two-arm randomized controlled trial and completed baseline and follow-up assessments at 4, 8, and 12 months. We used latent growth curve modeling techniques to analyze the data. Results showed that while all participants exhibited reductions in depression, meth use, and condomless sex, the intervention and comparison groups did not differ in changes over time. However, we did find a significant gender moderation effect, such that among men, those in the intervention arm reported greater reductions in meth use relative to those in the comparison group; reduced meth use was associated with reduced condomless sex, but not depression. In contrast, women in the intervention condition did not differ from women in the comparison condition in changes in any of the three outcome variables. Interventions targeting heterosexual women and men who use meth must be gender-specific, and take into account the unique vulnerabilities and experiences of women, including the perceived positive aspects of using meth, gendered power dynamics, higher depression, and violence.

Intentional and Unintentional Condom Breakage and Slippage in the Sexual Interactions of Female and Male Sex Workers and Clients in Mombasa, Kenya

We examined why male condoms broke or slipped off during commercial sex and the actions taken in response among 75 female and male sex workers and male clients recruited from 18 bars/nightclubs in Mombasa, Kenya. Most participants (61/75, 81%) had experienced at least one breakage or slippage during commercial sex. Many breakages were attributed to the direct actions of clients. Breakages and slippages fell into two main groups: those that were intentionally caused by clients and unintentional ones caused by inebriation, forceful thrusting during sex and incorrect or non-lubricant use. Participant responses included: stopping sex and replacing the damaged condoms, doing nothing, getting tested for HIV, using post-exposure prophylaxis and washing. Some sex workers also employed strategies to prevent the occurrence of condom breakages. Innovative client-oriented HIV prevention and risk-reduction interventions are therefore urgently needed. Additionally, sex workers should be equipped with skills to recognize and manage breakages.

Projecting the impact of anal intercourse on HIV transmission among heterosexuals in high HIV prevalence settings

Whereas penile vaginal intercourse (VI) is thought to be the dominant mode of HIV transmission in sub-Saharan Africa, cross-sectional studies in the region indicate the preponderance of heterosexual anal intercourse (AI) among high activity groups. A dynamic, heterosexual core group model with risk of infection through both vaginal and anal pathways is formulated and comprehensively analysed. The model is coupled to a general population model and fitted to HIV prevalence data for Zimbabwe in order to explore the parameter space related to heterosexual AI. The model fit supports a core group size ranging between 5-20% and exposure risk to AI in excess of 50%. The control effort quantified by the reproductive number (R_A) at commencement of the epidemic corresponds to R₀=4.40. With the contribution of heterosexual AI to Zimbabwe's (and that of the sub-Saharan African region) epidemic unknown, the study apportioned infections between the two infection pathways. New infections due to VI ranged from 2-4.5% and 0.5-2.7% from heterosexual AI. The study estimates infection probabilities ranging from 0.15 to 0.35 for both receptive and infective AI. By quantifying the incidence due to VI and AI risks, we put emphasis on the necessity for targeted interventions. To project the potential impact of heterosexual AI in high HIV prevalence settings, we raised the core group size to 20% in the year 2010 coinciding with reported heterosexual AI prevalence outside of Africa and allowed the proportion of infection risk associated with AI to vary. Prevalence and incidence projections were made up to the year 2020 starting from a baseline value of zero exposure to AI transmission risk per sex act, progressively increasing exposure to 50% and 70% respectively. A 50% exposure to AI would result in HIV prevalence scaling up by 23% from the baseline values in year 2020. Increasing exposure to 70% was projected to increase HIV prevalence by 38% in year 2020. The HIV infection risks associated with AI are recognised and inform HIV policy for men who have sex with men, yet the same risks are ignored in HIV intervention programmes for heterosexuals. This study highlights the potential danger of increasing prevalence of heterosexual AI in settings with high HIV prevalence. Evolving and globally cross pollinating sexual behaviors compel for dovetailing HIV policy making with sexology.

Minority Men Who Have Sex with Men Demonstrate Increased Risk for HIV Transmission

Black and Hispanic (minority) MSM have a higher incidence of HIV than white MSM. Multiple sexual partners, being under the influence of drugs and/or alcohol during sex, having a detectable HIV-1 RNA, and non-condom use are factors associated with HIV transmission. Using data from the Veterans Aging Cohort Study, we consider minority status and sexual orientation jointly to characterize and compare these factors. White non-MSM had the lowest prevalence of these factors (p < 0.001) and were used as the comparator group in calculating odds ratios (OR). Both MSM groups were more likely to report multiple sex partners (white MSM OR 7.50; 95 % CI 5.26, 10.71; minority MSM OR 10.24; 95 % CI 7.44, 14.08), and more likely to be under the influence during sex (white MSM OR 2.15; 95 % CI 1.49, 3.11; minority MSM OR 2.94; 95 % CI 2.16, 4.01). Only minority MSM were more likely to have detectable HIV-1 RNA (OR 1.87; 95 % CI 1.12, 3.11). Both MSM groups were more likely to use condoms than white non-MSM. These analyses suggest that tailored interventions to prevent HIV transmission among minority MSM are needed, with awareness of the potential co-occurrence of risk factors.

Stigma, access to healthcare, and HIV risks among men who sell sex to men in Nigeria

INTRODUCTION

Among men who have sex with men (MSM), men who sell sex (MSS) may be subject to increased sexual behaviour-related stigma that affects uptake of healthcare and risk of sexually transmitted infections (STIs). The objectives of this study were to characterize stigma, access to care, and prevalence of HIV among MSS in Nigeria.

METHODS

Respondent-driven sampling was used to recruit MSM in Abuja and Lagos into the ongoing TRUST/RV368 study, which provides HIV testing and treatment. Detailed behavioural data were collected by trained interviewers. MSS were identified by self-report of receiving goods or money in exchange for sex with men. Poisson regression with robust error variance was used to explore the impact of sex-selling on the risk of HIV.

RESULTS

From 12 initial seed participants, 1552 men were recruited from March 2013-March 2016. Of these, 735 (47.4%) reported sex-selling. Compared to other MSM, MSS were younger (median 22 vs. 24 years, p < 0.001) and more likely to identify as gay/homosexual (42.4% vs. 31.5%, p < 0.001). MSS were more likely to report perceived and experienced stigmas such as healthcare avoidance (27.6% vs. 21.5%, p = 0.005) and verbal harassment (39.2% vs. 26.8%, p < 0.001). Total HIV prevalence was 53.4%. After controlling for other factors, HIV prevalence among MSS was similar to that observed among other MSM (relative risk 0.94 [95% confidence interval 0.84-1.05]).

CONCLUSION

These data highlight increased sexual behaviour-related stigma affecting MSS, as compared with other MSM, that limits uptake of healthcare services. The distinct characteristics and risks among MSS suggest the need for specific interventions to optimize linkage to HIV prevention and treatment services in Nigeria.

Hazardous Alcohol Use Associated with Increased Sexual Risk Behaviors Among People Who Inject Drugs

BACKGROUND

Alcohol is associated with a multitude of severe health consequences. While risk behaviors related to illicit drug use are commonly studied among people who inject drugs (PWID), the role of alcohol use has received substantially less attention in this population. We explored whether drug and sexual risk behaviors as well as experiences of violence were associated with hazardous alcohol use in a cohort of PWID.

METHODS

Analyses were conducted using observational data from a prospective cohort of community-recruited HIV-negative PWID in Vancouver, Canada. We used the U.S. National Institute on Alcohol Abuse and Alcoholism definition of hazardous alcohol use (i.e., >14 drinks/wk or >4 drinks on 1 occasion for men, and >7 drinks/wk or >3 drinks on 1 occasion for women). We used multivariable generalized estimating equations (GEE) to identify the factors associated with hazardous alcohol use.

RESULTS

Between 2006 and 2012, 1,114 HIV-negative individuals were recruited, and 186 (16.7%) reported hazardous alcohol use in the previous 6 months at baseline. In multivariable GEE analyses, having multiple sex partners (adjusted odds ratio [AOR] = 1.25), history of sexually transmitted infection (AOR = 1.50), experiencing violence (AOR = 1.36), and incarceration (AOR = 1.29) were each independently associated with hazardous alcohol use. Caucasian ethnicity (AOR = 0.56), ≥ daily heroin injection (AOR = 0.81), and engagement in addiction treatment (AOR = 0.84) were negatively associated with hazardous alcohol use (all p < 0.05).

CONCLUSIONS

A considerable proportion of PWID reported hazardous alcohol use, which was independently associated with reporting sexual, but not drug-related, HIV risk behaviors and experiencing recent violence. Findings suggest a need to integrate regular screening and evidence-based alcohol interventions into treatment efforts for PWID.

Attitudes to and Understanding of Risk of Acquisition of HIV Over Time: Design and Methods for an Internet-based Prospective Cohort Study Among UK Men Who Have Sex With Men (the AURAH2 Study)

Background

The annual number of new human immunodeficiency virus (HIV) infections among men who have sex with men (MSM) has risen in the United Kingdom and, of those who are HIV positive, the proportion undiagnosed is high.

Objective

The prospective AURAH2 study aims to assess factors associated with HIV acquisition among MSM in the United Kingdom and to investigate changes over time within individuals in sexual behavior and HIV-testing practices.

Methods

AURAH2 is a prospective study among MSM without diagnosed HIV, aiming to recruit up to 1000 sexually active MSM attending sexual health clinics in London and Brighton in the United Kingdom. Participants complete an initial paper-based questionnaire, followed by online follow-up questionnaires every 4 months collecting sociodemographic, health and behavioral data, including sexual behavior, recreational and other drug use, HIV testing practices, and pre-exposure prophylaxis use, over a planned 3-year period.

Results

The study is ongoing.

Conclusions

The results from AURAH2 study will provide important insight into established and emerging risk behaviors that may be associated with acquisition of HIV in MSM in the United Kingdom, changes over time within individuals in sexual behavior, and information on HIV testing practices. These data will be crucial to inform future HIV prevention strategies.

Factors Associated With Condom Breakage During Anal Intercourse: A Cross-Sectional Study of Men Who Have Sex With Men Recruited in an Online Survey

Background

Within the United States, HIV affects men who have sex with men (MSM) disproportionally compared to the general population. In 2011, MSM represented nearly two-thirds of all new HIV infections while representing less than 2% of the US male population. Condoms continue to be the foundation of many HIV prevention programs; however, the failure rate of condoms during anal intercourse among MSM is estimated to be 0.5% to 8%, and condom breakages leave those affected at high risk for HIV transmission.

Objective

Estimate the frequency of condom breakage and associated demographic and behavioral factors during last act of anal intercourse using data from a national online HIV prevention survey of MSM.

Methods

From March 19 to April 16, 2009, data were collected on 9005 MSM through an online survey of US MSM recruited through a social networking site. Using multivariable logistic regression and controlling for several demographic and sexual risk behaviors, we estimated odds ratios of the association between condom breakage and several risk factors.

Results

In the study, 8063 participants reported having at least one male sexual partner in the last 12 months. The median age of participants was 21 years (range 18-65). More than two-thirds (68.2%, 5498/8063) reported anal intercourse during last sex and 16.90% (927/5498) reported using a condom during last anal intercourse act. Condom breakage was reported by 4.4% (28/635) participants who engaged in receptive anal intercourse and 3.5% (16/459) participants who engaged in insertive anal intercourse, with an overall failure rate of 4.0% (95% CI 3.2%-6.0%). Age (adjusted odds ratio [aOR] per 5 years: 0.53 (95% CI 0.30-0.94), number of male sex partners (aOR per 5 sex partners: 1.03 (95% CI 1.00-1.08), and being high or buzzed during sex with a casual sex partner (aOR: 3.14, 95% CI 1.02-9.60) were associated with condom breakage.

Conclusions

Our results indicate condom breakage is an important problem for MSM that may be more common for younger men, for men with more partners, and during sex with casual partners after alcohol consumption or drug use. A better understanding of why condom breakage occurs more often in these groups is needed to improve educational efforts. Further, during this time of expanded interest in new condom designs, consideration should be given to how condom design might minimize breakage during anal sex.

Drinking Patterns and HIV Risk Behaviors Among Black and Latino Men Who Have Sex Within Los Angeles County

Alcohol, the most widely used substance among men who have sex with men (85%), remains an important factor in HIV research among this high-risk population. However, research on alcohol use among Black and Latino men who have sex with men (BLMSM), a population disproportionately affected by HIV in the United States, is limited and inconclusive. This study explored sociodemographic and HIV risk with daily heavy and low-risk drinking patterns among BLMSM. BLMSM (N = 188) aged 18 to 40 years were recruited through social media, local colleges, heteronormative clubs, private men’s groups, gay establishments, and organized events in Los Angeles County. Participants completed self-administered questionnaires. Fisher’s exact tests revealed significant relationships between drinking patterns and condomless insertive anal intercourse (p = .001), race (p < .001), age (p = .02), and perception of alcohol-related HIV risk (p = .007). The Fisher’s exact tests findings for age held true in the multiple regression model (p = .014). Findings suggest that BLMSM who engage in higher risk drinking also engage in alcohol-related HIV risk. Culturally competent interventions should consider including a combined focus to explore the synergy between risky drinking patterns and HIV risk among BLMSM.

Racial/Ethnic Difference in HIV-related Knowledge among Young Men who have Sex with Men and their Association with Condom Errors

OBJECTIVE

HIV disproportionately affects young men who have sex with men, and knowledge about HIV transmission is one factor that may play a role in high rate of infections for this population. This study examined racial/ethnic differences in HIV knowledge among young men who have sex with men in the USA and its correlation to condom usage errors.

DESIGN

Participants included an ethnically diverse sample of 344 young men who have sex with men screened from an ongoing longitudinal cohort study. Eligible participants were between the ages of 16 and 20 years, born male, and had previously had at least one sexual encounter with a man and/or identify as gay or bisexual. This analysis is based on cross-sectional data collected at the baseline interview using computer assisted self-interviewing (CASI) software.

SETTING

Chicago, IL, USA.

METHOD

We utilised descriptive and inferential statistics, including ANOVA and Tukey's Post hoc analysis to assess differences in HIV knowledge by level of education and race/ethnicity, and negative binomial regression to determine if HIV knowledge was associated with condom errors while controlling for age, education and race/ethnicity.

RESULTS

The study found that Black men who have sex with men scored significantly lower (average score=67%; p<.05) than their White counterparts (average score=83%) on a measure of HIV knowledge (mean difference=16.1%, p<.001). Participants with less than a high school diploma and those with a high school diploma/GED only had lower knowledge scores, on average (66.4%, 69.9%, respectively) than participants who had obtained post-high school education (78.1%; mean difference=11.7%, 8.2% respectively, ps<.05). In addition, controlling for age, race and level of education, higher HIV knowledge scores were associated with fewer condom errors (Exp B =.995, CI 0.992-0.999, p<0.05).

CONCLUSION

These findings stress the need to for increased attention to HIV transmission-related educational activities targeting the social realities and unique risk mechanisms of young men who have sex with men.

A systematic review of evidence to inform HIV prevention interventions among men who have sex with men in Europe

An estimated 42% of all newly diagnosed HIV cases in Europe in 2013 were transmitted during sex between men. This review was performed to identify and describe studies evaluating the efficacy and effectiveness of HIV prevention interventions among men who have sex with men (MSM), in relation to implementation data from European settings. A systematic search was performed individually for 24 interventions.Data were extracted from studies including efficacy or implementation data from European settings,appraised for efficacy, implementation and plausibility, and assigned a grade (1-4) according to the Highest Attainable Standard of Evidence (HASTE)framework. Four interventions (condom use, peer outreach,peer-led groups, and using universal coverage of antiretroviral treatment and treatment as prevention)were assigned the highest HASTE grade, 1. Another four interventions were assigned 2a for probable recommendation, including voluntary counseling and testing for HIV, using condom-compatible lubricant,using post-exposure prophylaxis, and individual counselling for MSM living with HIV. In addition, seven interventions were assigned a grade of 2b, for possible recommendation. Encouragingly, 15 interventions were graded to be strongly, probably or possibly recommended.In the relatively resource-rich European setting, there is an opportunity to provide global leadership with regard to the regional scale-up of comprehensive HIV prevention interventions for MSM.

Sexual partnerships and considerations for HIV antiretroviral pre-exposure prophylaxis utilization among high-risk substance using men who have sex with men

Men who have sex with men (MSM) remain at great risk of HIV in the United States, representing 65 % of incident HIV infections. One factor contributing to the high rate of HIV infection among MSM is use of "recreational" drugs that are highly associated with unprotected anal sex. Pre-exposure chemoprophylaxis (PrEP) is a novel biomedical HIV prevention strategy that has the potential to reduce HIV transmission in MSM. Main and casual sex partners play a role in HIV prevention efforts for MSM. The study aimed to qualitatively explore the perceived influences of sexual relationships on promoting and inhibiting PrEP use among high-risk MSM who report regular drug use. Semi-structured qualitative interviews were conducted with 40 participants recruited in Boston, Massachusetts. Data were analyzed using descriptive qualitative analysis. Casual partners presented a distinct set of concerns from primary partnerships. MSM generally viewed main partners as a potential source of support for taking PrEP. Given their informal and often temporary nature, PrEP disclosure to casual partners was considered unnecessary. HIV-related stigma and substance use were also perceived as barriers to discussing PrEP use with casual partners. MSM articulated a high degree of personal agency regarding their ability to take PrEP. Findings suggest that behavioral interventions to improve PrEP utilization and adherence for high-risk MSM should be tailored to sex partner type and the parameters established between sex partners. Approaches to PrEP disclosure and partner engagement should be informed by the relative benefits and limitations characterized by these different types of relationships.

HIV prevalence and factors associated with HIV infection among men who have sex with men in Cameroon

Introduction

Despite men who have sex with men (MSM) being a key population for HIV programming globally, HIV epidemiologic data on MSM in Central Africa are sparse. We measured HIV and syphilis prevalence and the factors associated with HIV infection among MSM in Cameroon.

Methods

Two hundred and seventy-two and 239 MSM aged ≥18 from Douala and Yaoundé, respectively, were recruited using respondent-driven sampling (RDS) for this cross-sectional surveillance study in 2011. Participants completed a structured questionnaire and HIV and syphilis testing. Statistical analyses, including RDS-weighted proportions, bootstrapped confidence intervals and logistic regressions, were used.

Results

Crude and RDS-weighted HIV prevalence were 28.6% (73/255) and 25.5% (95% CI 19.1–31.9) in Douala, and 47.3% (98/207) and 44.4% (95% CI 35.7–53.2) in Yaoundé. Active syphilis prevalence in total was 0.4% (2/511). Overall, median age was 24 years, 62% (317/511) of MSM identified as bisexual and 28.6% (144/511) identified as gay. Inconsistent condom use with regular male partners (64.1%; 273/426) and casual male and female partners (48.5%; 195/402) was common, as was the inconsistent use of condom-compatible lubricants (CCLs) (26.3%; 124/472). In Douala, preferring a receptive sexual role was associated with prevalent HIV infection [adjusted odds ratio (aOR) 2.33, 95% CI 1.02–5.32]. Compared to MSM without HIV infection, MSM living with HIV were more likely to have ever accessed a health service targeting MSM in Douala (aOR 4.88, 95% CI 1.63–14.63). In Yaoundé, MSM living with HIV were more likely to use CCLs (aOR 2.44, 95% CI 1.19–4.97).

Conclusions

High HIV prevalence were observed and condoms and CCLs were used inconsistently indicating that MSM are a priority population for HIV prevention, treatment and care services in Douala and Yaoundé. Building the capacity of MSM community organizations and improving the delivery and scale-up of multimodal interventions for MSM that are sensitive to concerns about confidentiality and the complex individual, social, community-level and policy challenges are needed to successfully engage young MSM in the continuum of HIV care. In addition to scaling up condom and CCL access, evaluating the feasibility of novel biomedical interventions, including antiretroviral pre-exposure prophylaxis and early antiretroviral therapy for MSM living with HIV in Cameroon, is also warranted.

Condoms and condiments: compatibility and safety of personal lubricants and their use in Africa

Previous research on the use of personal lubricants for sexual intercourse is limited and has primarily focused on condom compatibility and breakage, with only recent limited assessment of lubricant safety and possible epidemiologic implications. This article discusses the global evidence of lubricant compatibility with latex condoms and biological safety of lubricants, as well as documentation of lubricant use and current guidelines for HIV prevention programming in Africa. Data on lubricant compatibility with condoms are less available than commonly realized, and many lubricant products may not have been thoroughly tested for safety due to flexible regulatory environments. Recent laboratory and study findings from microbicides research also suggest that some water-based lubricants may have safety issues. Some African populations are using several types of lubricants, especially oil-based petroleum jellies, and receive little evidence-based guidance. More research is needed from the medical community to guide prevention programming.

Results of a pilot study to reduce methamphetamine use and sexual risk behaviors among methamphetamine-using men who have sex with men (MSM) not currently in treatment

Methamphetamine use, which has been linked to unprotected anal intercourse and incident HIV infection, is an important contributor to HIV transmission among men who have sex with men (MSM). The purpose of this study was to develop and pilot test a single-session motivational interviewing (MI) intervention for reducing HIV risk among an out-of-treatment sample of MSM who use methamphetamine. MSM who use methamphetamine (n = 39) were recruited in 2008 and 2009 in North Carolina. They completed baseline data collection and a single-session MI intervention. Eighty percent completed a follow-up interview two months after enrollment. Men reported reductions in methamphetamine use during the previous 60 days from an average of 9.4 days at baseline to 3.3 days at follow-up (p < 0.05) and unprotected anal intercourse from an average of 4.8 sex partners during the previous 60 days at baseline to 2.9 at follow-up (p < 0.05). Self-reported unprotected anal intercourse at last sex with a nonprimary partner decreased significantly (from 81% at baseline to 25% at follow-up; p = 0.001). These results suggest that a single-session MI intervention may be useful for reducing methamphetamine use and sexual risk among MSM who use methamphetamine, especially in settings where multisession interventions are not feasible.

Joint effects of alcohol consumption and high-risk sexual behavior on HIV seroconversion among men who have sex with men

OBJECTIVE

To estimate the effects of alcohol consumption and number of unprotected receptive anal intercourse partners on HIV seroconversion while appropriately accounting for time-varying confounding.

DESIGN

Prospective cohort of 3725 HIV-seronegative men in the Multicenter AIDS Cohort Study between 1984 and 2008.

METHODS

Marginal structural models were used to estimate the joint effects of alcohol consumption and number of unprotected receptive anal intercourse partners on HIV seroconversion.

RESULTS

Baseline self-reported alcohol consumption was a median 8  drinks/week (quartiles: 2, 16), and 30% of participants reported multiple unprotected receptive anal intercourse partners in the prior 2 years. Five hundred and twenty-nine HIV seroconversions occurred over 35 ,870 person-years of follow-up. After accounting for several measured confounders using a joint marginal structural Cox proportional hazards model, the hazard ratio for seroconversion associated with moderate drinking (1-14 drinks/week) compared with abstention was 1.10 [95% confidence limits: 0.78, 1.54] and for heavy drinking (>14 drinks/week) was 1.61 (95% confidence limits: 1.12, 2.29) (P for trend <0.001). The hazard ratios for heavy drinking compared with abstention for participants with 0-1 or more than 1 unprotected receptive anal intercourse partner were 1.37 (95% confidence limits: 0.88, 2.16) and 1.96 (95% confidence limits: 1.03, 3.72), respectively (P for interaction = 0.42).

CONCLUSION

These findings suggest that alcohol interventions to reduce heavy drinking among men who have sex with men should be integrated into existing HIV prevention activities.

A cautionary tale: risk reduction strategies among urban American Indian/Alaska Native men who have sex with men

American Indian and Alaska Native (AIAN) men who have sex with men (MSM) are considered particularly high risk for HIV transmission and acquisition. In a multi-site cross-sectional survey, 174 AIAN men reported having sex with a man in the past 12 months. We describe harm reduction strategies and sexual behavior by HIV serostatus and seroconcordant partnerships. About half (51.3%) of the respondents reported no anal sex or 100% condom use and 8% were in seroconcordant monogamous partnership. Of the 65 men who reported any sero-adaptive strategy (e.g., 100% seroconcordant partnership, strategic positioning or engaging in any strategy half or most of the time), only 35 (54.7%) disclosed their serostatus to their partners and 27 (41.5%) tested for HIV in the past 3 months. Public health messages directed towards AIAN MSM should continue to encourage risk reduction practices, including condom use and sero-adaptive behaviors. However, messages should emphasize the importance of HIV testing and HIV serostatus disclosure when relying solely on sero-adaptive practices.

Successes and challenges of HIV prevention in men who have sex with men

Men who have sex with men (MSM) have been substantially affected by HIV epidemics worldwide. Epidemics in MSM are re-emerging in many high-income countries and gaining greater recognition in many low-income and middle-income countries. Better HIV prevention strategies are urgently needed. Our review of HIV prevention strategies for MSM identified several important themes. At the beginning of the epidemic, stand-alone behavioural interventions mostly aimed to reduce unprotected anal intercourse, which, although somewhat efficacious, did not reduce HIV transmission. Biomedical prevention strategies reduce the incidence of HIV infection. Delivery of barrier and biomedical interventions with coordinated behavioural and structural strategies could optimise the effectiveness of prevention. Modelling suggests that, with sufficient coverage, available interventions are sufficient to avert at least a quarter of new HIV infections in MSM in diverse countries. Scale-up of HIV prevention programmes for MSM is difficult because of homophobia and bias, suboptimum access to HIV testing and care, and financial constraints.

Condom use problems during anal sex among men who have sex with men (MSM): findings from the Safe in the City study

Our research aims were to: (1) assess the prevalence of two condom use problems: breakage or slippage and partial use (delayed application or early removal) among men who have sex with men (MSM) seeking services in urban US STD clinics; and (2) examine the association between these condom use problems and participant, partner and partnership characteristics. Analysis was restricted to HIV-negative MSM who reported having anal sex at least once in the preceding 3 months and who completed both the baseline and 3 month follow-up assessments. Two models were fitted using the generalized estimating equations (GEE) approach. A total of 263 MSM (median age=32 years) reported 990 partnerships. Partnerships with no condom use 422 (42.6%) were excluded. Thus, 207 MSM and 568 partnerships were included. Among condom users, 100% use was reported within 454 partnerships (79.9%) and <100% within 114 (20.1%), and 21(3.7%) reported both condom use problems, 25 (4.4%) reported only breakage, 67 (11.8%) reported only partial use, and 455 (80.1%) reported no errors. The breakage or slippage and partial use rates per condom used were 3.4% and 11.2%, respectively. A significantly higher rate of breakage or slippage occurred among non-main partnerships. Characteristics associated with increased odds for condom breakage or slippage were: lower education level (OR=2.78; CI: 1.1-7.5), non-main partner status (OR=4.1; CI: 1.5-11.7), and drunk or high during sex (OR=2.0; CI: 1.1-3.8), and for partial use: lower education level (OR=2.6; CI: 1.0-6.6), perceived partner sexually transmitted infections (STI) risk (OR=2.4; CI: 1.3-4.2), and inconsistent condom use (OR=3.7; CI: 2.0-6.6). A high percentage of MSM partnerships reported no condom use and among condom users, a sizable proportion did not use them consistently or correctly. MSM may benefit from interventions designed to increase proficiency for condom use with a particular focus on the behaviors of inconsistent and partial condom use.

High and persistent HIV seroincidence in men who have sex with men across 47 U.S. cities

OBJECTIVE

To provide HIV seroincidence data among men who have sex with men (MSM) in the United States and to identify predictive factors for seroconversion.

METHODS

From 1998-2002, 4684 high-risk MSM, age 18-60 years, participated in a randomized, placebo-controlled HIV vaccine efficacy trial at 56 U.S. clinical trial sites. Demographics, behavioral data, and HIV status were assessed at baseline and 6 month intervals. Since no overall vaccine efficacy was detected, data were combined from both trial arms to calculate HIV incidence based on person-years (py) of follow-up. Predictors of seroconversion, adjusted hazards ratio (aHR), were evaluated using a Cox proportional hazard model with time-varying covariates.

RESULTS

Overall, HIV incidence was 2.7/100 py and was relatively uniform across study sites and study years. HIV incidence was highest among young men and men reporting unprotected sex, recreational drug use, and a history of a sexually transmitted infection. Independent predictors of HIV seroconversion included: age 18-30 years (aHR = 2.4; 95% CI 1.4,4.0), having >10 partners (aHR = 2.4; 95% CI 1.7,3.3), having a known HIV-positive male sex partner (aHR = 1.6; 95% CI 1.2, 2.0), unprotected anal intercourse with HIV positive/unknown male partners (aHR = 1.7; 95% CI 1.3, 2.3), and amphetamine (aHR = 1.6; 95% CI 1.1, 2.1) and popper (aHR = 1.7; 95% CI 1.3, 2.2) use.

CONCLUSIONS

HIV seroincidence was high among MSM despite repeated HIV counseling and reported declines in sexual risk behaviors. Continuing development of new HIV prevention strategies and intensification of existing efforts will be necessary to reduce the rate of new HIV infections, especially among young men.

HIV and club drugs in emerging adulthood

PURPOSE OF REVIEW

To evaluate the incidence of club drug use in pediatric patients, especially those aged 13-25, and how it relates to the spread of HIV.

RECENT FINDINGS

Transmission of HIV among younger patients has become largely associated with risky sexual behaviors, as the rate of transmission from vertical infection and intravenous drug use has decreased. Use of club drugs in emerging adult populations contributes to the HIV epidemic through a combination of decreased inhibitions as well as physiological effects that increase high-risk sexual practices. Robust data exists linking the use of club drugs by the men who have sex with men population with spread of HIV, but this data in other at-risk populations (e.g. African Americans) is not as robust. Additional research is needed to identify the rates of transmission among adolescents and emerging adults, as well as knowledge, attitudes, beliefs, and practices that affect HIV transmission in this population.

SUMMARY

Use of club drugs by adolescents and emerging adults contributes to the current rate of HIV transmission among this age group.

Condom use errors and problems: a global view

Background Significantly more research attention has been devoted to the consistency of condom use, with far fewer studies investigating condom use errors and problems. The purpose of this review was to present the frequency of various condom use errors and problems reported worldwide. Methods: A systematic literature search was conducted for peer-reviewed articles, published in English-language journals between 1995 and 2011. Results: Fifty articles representing 14 countries met criteria for inclusion. The most common errors included not using condoms throughout sex, not leaving space at the tip, not squeezing air from the tip, putting the condom on upside down, not using water-based lubricants and incorrect withdrawal. Frequent problems included breakage, slippage, leakage, condom-associated erection problems, and difficulties with fit and feel. Prevalence estimates showed great variation across studies. Prevalence varied as a function of the population studied and the period assessed. Conclusion: Condom use errors and problems are common worldwide, occurring across a wide spectrum of populations. Although breakage and slippage were most commonly investigated, the prevalence of other condom use errors and problems found in this review were substantially higher. As a framework for understanding the role of condom errors and problems in inadequate protection, we put forward a new model: the Condom Use Experience model. This model can be used to generate testable hypotheses for future research. Addressing condom use errors and problems in research and interventions is crucial to closing the gap between the perfect use and typical use of condoms.

Static behavioral effects on gonorrhea transmission dynamics in a MSM population

An SIS/SAS model of gonorrhea transmission in a population of highly active men-having-sex-with-men (MSM) is presented in this paper to study the impact of safe behavior on the dynamics of gonorrhea prevalence. Safe behaviors may fall into two categories-prevention and self-awareness. Prevention will be modeled via consistent condom use and self-awareness via STD testing frequency. Stability conditions for the disease free equilibrium and endemic equilibrium are determined along with a complete analysis of global dynamics. The control reproductive number is used as a means for measuring the effect of changes to model parameters on the prevalence of the disease. We also find that appropriate intervention would be in the form of a multifaceted approach at overall risk reduction rather than tackling one specific control individually.

Using a modified intervention mapping approach to develop and refine a single-session motivational intervention for methamphetamine-using men who have sex with men

There is an ongoing need for the development and adaptation of behavioral interventions to address behaviors related to acquisition and transmission of infectious diseases and for preventing the onset of chronic diseases. This paper describes the application of an established systematic approach to the development of a behavioral intervention to reduce sexual risk behaviors for HIV among men who have sex with men and who use methamphetamine. The approach includes six steps: (1) a needs assessment; (2) preparing matrices of proximal program objectives; (3) selecting theory-based methods and practical strategies; (4) producing program components and materials; (5) planning for program adoption, implementation, and sustainability; and (6) planning for evaluation. The focus of this article is on the intervention development process; therefore the article does not describe steps 5 and 6. Overall the process worked well, although it had to be adapted to fit the sequence of events associated with a funded research project. This project demonstrates that systematic approaches to intervention development can be applied even in research projects where some of the steps occur during the proposal writing process rather than during the actual project. However, intervention developers must remain flexible and be prepared to adapt the process to the situation. This includes being ready to make choices regarding intervention efficacy versus feasibility and being willing to select the best intervention that is likely to be delivered with available resources rather than an ideal intervention that may not be practical.

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.

Estimating the proportion of HIV transmissions from main sex partners among men who have sex with men in five US cities

BACKGROUND

HIV incidence in the United States among men who have sex with men (MSM) has been increasing since 2000, and MSM remain the most heavily impacted risk group in the US HIV epidemic.

METHODS

We modeled HIV transmissions, using data from MSM in five US cities from the National HIV Behavioral Surveillance System, the HIVNET Vaccine Preparedness Study, and other published data. Annual HIV transmissions were estimated by partner type (main or casual) and by sex type (receptive anal intercourse, insertive anal intercourse, or oral sex).

RESULTS

Sixty-eight percent [95% confidence interval (CI) 58-78) of HIV transmissions were from main sex partners because of a higher number of sex acts with main partners, more frequent receptive roles in anal sex with main partners, and lower condom use during anal sex with main partners. By sex type, 69% (95% CI 59-79) of infections were from receptive anal intercourse, 28% (95% CI 19-38) were from insertive anal intercourse, and 2% (95% CI 0-5) were from oral sex. The model-based estimated HIV incidence rate was 2.2% (95% CI 1.7-2.7) per year. Sensitivity analyses demonstrated estimates of transmission from main sex partners as low as 52% (95% CI 41-62) and as high as 74% (95% CI 68-80).

CONCLUSION

According to our model, most HIV transmissions among MSM in five US cities are from main sex partners. HIV prevention efforts should take into account the risks of HIV transmissions in male partnerships, and couples-based HIV prevention interventions for MSM should be given high priority in the US HIV prevention research portfolio.

Estimating the risk of blood donation associated with HIV risk behaviours

A blood donor questionnaire and declaration, with deferral of potential donors at a higher risk of blood-borne infections, was introduced in Australia in the mid-1980s to reduce the risk of donation of HIV-infected blood. However, the absolute risk of HIV transmission through blood donation from high-HIV-risk donors has not been estimated. This study presents a new method of assessing the risk posed to the blood supply by selected HIV risk behaviours. A model was developed to estimate the probability of blood donation during the window period for HIV infection. Five scenarios for blood donors were considered: (1) men who have sex with men (MSM), (2) men who have sex with women in Australia, (3) women who have sex with partners from countries with a high HIV prevalence, (4) men who have sex with commercial sex workers in Australia and (5) people injecting drugs used once in a year. Those estimated to be at highest risk of becoming infected and donating in the window period were MSM. Women who have sex with men from countries of high HIV prevalence are at greater risk than men who have sex with female sex workers from Australia. These three groups under current Australian guidelines are deferred from donating blood for 12 months. In Australia, a single episode of injecting drug use is associated with very low risk of HIV transmission. The model presented in this study can be used to assess the impact of selected individual risk behaviours on the safety of the blood supply.

Viagra, methamphetamine, and HIV risk: results from a probability sample of MSM, San Francisco

OBJECTIVES

To determine the prevalence and factors of Viagra use in combination with crystal methamphetamine and its association with HIV risk behavior in a probability sample of men who have sex with men (MSM).

STUDY DESIGN

A cross-sectional, random-digit dial telephone survey of MSM in San Francisco conducted between June 2002 and January 2003.

RESULTS

Of the 1976 MSM, 13.5% used Viagra alone, 7.1% used methamphetamine without Viagra, 9.6% used Viagra with a mood-altering substance (excluding methamphetamine), and 5.1% used Viagra with methamphetamine. Of the MSM using Viagra with methamphetamine, 57% were HIV-infected and 24% of these men reported serodiscordant unprotected insertive intercourse. Viagra used with methamphetamine was independently associated with a higher risk of serodiscordant unprotected insertive intercourse, serodiscordant unprotected receptive intercourse, and a recent diagnosis of a sexually transmitted disease.

CONCLUSION

MSM who use Viagra with crystal methamphetamine have high prevalence rates of HIV and engage in HIV risk behaviors.

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.

Failure to embrace the barrier/condom use message

The objective of this study was to examine the consistency of barrier/condom use among men who have sex with men in the Kansas City metropolitan area. The authors sought to determine if barrier/condom usage patterns were associated with the type of sex act and whether it was insertive or receptive, HIV testing frequency, and number of sexual partners. Data were extracted from a 2003 community health assessment of the gay, lesbian, bisexual, and transgendered community in the metropolitan area. The health assessment instrument was anonymous, self-administered, and distributed at events in that community. Responses from 623 men indicated that consistent use of a barrier/condom was low regardless of the sex act. There was no relationship between barrier/condom usage patterns and HIV testing frequency for any sex act or the number of sex partners, with the exception of anal intercourse. The authors concluded that a different approach is needed to translate the barrier/condom use message into a behavioral response.

Unintentional HIV exposures from young men who have sex with men who disclose being HIV-negative

OBJECTIVE

To evaluate the proportion of new sexual partners potentially exposed to HIV from young MSM who disclosed being HIV-negative.

DESIGN

Cross-sectional, observational study of men aged 23-29 years recruited from randomly sampled MSM-identified venues in six US cities.

METHODS

Participants were interviewed and tested for HIV. Analyses were restricted to MSM who reported last testing HIV-negative and having one or more new partners in the prior 6 months.

RESULTS

Of 1701 MSM who reported a total of 11 793 new partners, 1075 (63%) disclosed being HIV-negative to 4253 (36%) new partners before having sex with them for the first time. Of disclosers, 352 (33%) reported last testing HIV-negative > 1 year before their interview and 80 (7%) tested HIV-positive (HIV-infected unaware). By race, 24% of black, 5% of Hispanic, and 3% of white disclosers tested HIV-positive. Of the 4253 new partners, 296 (7%) were partners of the 80 HIV-infected unaware MSM. By race, 22% of new partners of black, 3% of new partners of Hispanic, and 4% of new partners of white MSM, were partners of HIV-infected unaware MSM who disclosed being HIV-negative.

CONCLUSIONS

Many new sex partners may be unintentionally exposed to HIV from young MSM, particularly those who are black and who disclose being HIV-negative based on an earlier test. Young MSM should test for HIV more frequently and consistently use condoms with all partners unless they are in a mutually monogamous relationship in which both partners have tested HIV-negative at least 3 months since their last potential HIV exposure.

Perceptions towards condom use, sexual activity, and HIV disclosure among HIV-positive African American men who have sex with men: implications for heterosexual transmission

Disproportionately high HIV/AIDS rates and frequent non-gay identification (NGI) among African American men who have sex with men or with both men and women (MSM/W) highlight the importance of understanding how HIV-positive African American MSM/W perceive safer sex, experience living with HIV, and decide to disclose their HIV status. Thirty predominately seropositive and non-gay identifying African American MSM/W in Los Angeles participated in three semi-structured focus group interviews, and a constant comparison method was used to analyze responses regarding condom use, sexual activity after an HIV diagnosis, and HIV serostatus disclosure. Condom use themes included its protective role against disease and pregnancy, acceptability concerns pertaining to aesthetic factors and effectiveness, and situational influences such as exchange sex, substance use, and suspicions from female partners. Themes regarding the impact of HIV on sexual activity included rejection, decreased partner seeking, and isolation. Serostatus disclosure themes included disclosure to selective partners and personal responsibility. Comprehensive HIV risk-reduction strategies that build social support networks, condom self-efficacy, communication skills, and a sense of collective responsibility among NGI African American MSM/W while addressing HIV stigma in the African American community as a whole are suggested.

Methamphetamine and sildenafil (Viagra) use are linked to unprotected receptive and insertive anal sex, respectively, in a sample of men who have sex with men

OBJECTIVES

There is evidence that methamphetamine and sildenafil (Viagra) use are associated with sexual risk behaviour among men who have sex with men (MSM). We investigated the association of methamphetamine, sildenafil, and other substance use with unprotected receptive and insertive anal sex among MSM by conducting an encounter specific analysis.

METHODS

Data were from a cross sectional, community based survey of MSM in San Francisco regarding behaviour during their most recent anal sex encounter. Mulitvariate regression analysed independent associations of specific substance use and demographic variables with unprotected anal sex behaviours.

RESULTS

The sample (n = 388) was diverse in race/ethnicity, age, income, education, HIV status, and homosexual/bisexual identification. More than half (53%) reported unprotected anal sex, including insertive (29%) and receptive (37%) during their most recent anal sex encounter; 12% reported unprotected insertive and 17% reported unprotected receptive anal sex with an HIV discordant or unknown partner. Methamphetamine was used by 15% and sildenafil was used by 6% of the men before or during the encounter; 2% used both drugs. In multivariate analysis controlling for demographic factors and other substance use, methamphetamine use was associated with unprotected receptive (odds ratio (OR), 2.03; 95% confidence interval (CI), 1.09 to 3.76) and sildenafil use was associated with unprotected insertive (OR, 6.51; CI, 2.46 to 17.24) anal sex. Effects were stronger with HIV discordant or unknown sex partners specifically.

CONCLUSION

Encounter specific associations of methamphetamine and sildenafil use with unprotected receptive and insertive anal sex, respectively, indicate the importance of assessment specificity and tailoring risk reduction efforts to address certain drugs and sexual behavioural roles among MSM.

Club Drugs and HIV Infection: A Review

Club drug use is common among populations with human immunodeficiency virus (HIV) and populations at high risk for HIV infection. Club drugs have a myriad of acute and chronic medical consequences. Club drug-related visits to the emergency department and admissions for treatment of substance use have increased dramatically over the past 15 years. Most epidemiological data support the role of club drugs in increasing sexual risk behavior, with some studies demonstrating an independent association between use of certain club drugs and HIV infection. The direct influence of club drugs on progression of HIV disease remains to be determined; however, club drugs may interact with certain retroviral medications and have been associated with decreased adherence to medication. Clinicians should ask all patients about patterns of club drug use, counsel patients about the risks associated with club drug use, and refer patients to appropriate behavioral treatment programs for substance use when clinically indicated.

Risk factors for HIV infection among men who have sex with men

OBJECTIVES

Risk factors for HIV acquisition were examined in a recent cohort of men who have sex with men (MSM).

DESIGN

A longitudinal analysis of 4295 HIV-negative MSM enrolled in a randomized behavioral intervention trial conducted in six US cities.

METHODS

MSM were enrolled and assessed for HIV infection and risk behaviors semi-annually, up to 48 months.

RESULTS

In multivariate analysis, men reporting four or more male sex partners, unprotected receptive anal intercourse with any HIV serostatus partners and unprotected insertive anal intercourse with HIV-positive partners were at increased risk of HIV infection, as were those reporting amphetamine or heavy alcohol use and alcohol or drug use before sex. Some depression symptoms and occurrence of gonorrhea also were independently associated with HIV infection. The attributable fractions of high number of male partners, use of alcohol or drugs before sex, and unprotected receptive anal intercourse with unknown status partners and the same with presumed negative partners accounted for 32.3, 29.0, 28.4 and 21.6% of infections, respectively.

CONCLUSIONS

The challenge is to develop strategies to identify men in need. Interventions are needed to help men reduce their number of sexual partners, occurrences of unprotected anal intercourse, alcohol or drug use before sex and address other mental health issues.

The methamphetamine epidemic: implications for HIV prevention and treatment

Methamphetamine and related amphetamine compounds are among the most commonly used illicit drugs, with over 35 million users worldwide. In the United States, admissions for methamphetamine treatment have increased dramatically over the past 10 years. Methamphetamine use is prevalent among persons with HIV infection and persons at risk for HIV, particularly among men who have sex with men. In addition to being associated with increased sexual risk behavior, methamphetamine causes significant medical morbidity, including neurologic deficits, cardiovascular compromise, dental decay, and skin infections, all of which may be worsened in the presence of HIV/AIDS. Methamphetamine use may also result in decreased medication adherence, particularly during "binging" episodes. Behavioral counseling remains the standard of treatment for methamphetamine dependence, although the effectiveness of most counseling interventions has not been rigorously tested. Pharmacologic and structural interventions may prove valuable additional interventions to reduce methamphetamine use.

Expanding research on the role of alcohol consumption and related risks in the prevention and treatment of HIV/AIDS

This article is a review of some of the major epidemiological, behavioral, biological, and integrative prevention research issues and priorities in the area of HIV/AIDS and alcohol consumption. Drinking alcohol increases both the risk for infection with HIV and related illnesses and the morbidity and mortality of patients who progress to AIDS. New and improved measurement procedures have helped in assessment of the complex patterns of alcohol use, identification of intervening explanatory mechanisms for risk behaviors and contexts, and determination of intervention outcomes. Both the direct and indirect effects of alcohol misuse appear to be major contributors to both the risk for infection with HIV and the transmission of HIV/AIDS at the individual and population levels. There is increasing evidence that perhaps no level of alcohol consumption is "safe" for those who are HIV infected and receiving antiretroviral treatment. Interdisciplinary basic behavioral and biomedical research is needed to develop comprehensive culturally appropriate strategies for programs that can be effectively delivered in community contexts in the United States and abroad and that focus on the integration of our understanding of individual behaviors, high-risk group membership, biological mechanisms, and the social and physical environments that place individuals at risk for HIV infection. High-priority topics include improving adherence to antiretroviral medications, prevention of infection in young minority women in the United States, and treatment of HIV+ pregnant women who are alcohol abusers to prevent adverse fetal outcomes, which is an international focus in under-resourced settings in Africa.

Associations of race/ethnicity with HIV prevalence and HIV-related behaviors among young men who have sex with men in 7 urban centers in the United States

Using data from a multisite venue-based survey of male subjects aged 15 to 22 years, we examined racial/ethnic differences in demographics, partner type, partner type-specific condom use, drug use, and HIV prevalence in 3316 US black, multiethnic black, Latino, and white men who have sex with men (MSM). We further estimated associations of these factors with HIV infection and their influence on racial/ethnic disparities in HIV prevalence. HIV prevalences were 16% for both black and multiethnic black participants, 6.9% for Latinos, and 3.3% for whites. Paradoxically, potentially risky sex and drug-using behaviors were generally reported most frequently by whites and least frequently by blacks. In a multiple logistic regression analysis, positive associations with HIV included older age, being out of school or work, sex while on crack cocaine, and anal sex with another male regardless of reported condom use level. Differences in these factors did not explain the racial/ethnic disparities in HIV prevalence, with both groups of blacks experiencing more than 9 times and Latinos experiencing approximately twice the fully adjusted odds of infection compared with whites. Understanding racial/ethnic disparities in HIV risk requires information beyond the traditional risk behavior and partnership type distinctions. Prevention programs should address risks in steady partnerships, target young men before sexual initiation with male partners, and tailor interventions to men of color and of lower socioeconomic status.

A National Survey of Clinic Sexual Histories for Sexually Transmitted Infection and HIV Screening

BACKGROUND

Optimal elements of a sexual history for sexually transmitted infection (STI) and HIV risk assessment remain undefined.

GOAL

The goal of this study was to describe sexual histories in use at STI clinics across the United States.

STUDY

This study consisted of a cross-sectional survey of facilities in cities with populations >200,000 (n = 65). Within each city, a public health STI clinic (71% of the sample) or other STI care facility (29%) was randomly selected and sexual history forms were requested. Information was obtained from 48 clinics (74% response).

RESULTS

Most forms recorded information on symptoms and prior STI (96%), condom use (88%), other contraception (85%), and numbers and gender (83%) of sex partners. Common HIV risk questions were injecting drug use (IDU; 94%), sex for drugs or money (58%), and sex with an HIV-positive or IDU partner (52%). Ascertainment of time during which risks occurred (contact periods) varied from the past 14 days to the past 12 months, with only 38% of clinics using any 1 time period. Few histories (17%) incorporated questions for men who have sex with men (MSM). Only 2 (4%) had space to record information about sexual behaviors by the HIV status of the sex partner. Condom use was infrequently assessed specifically for vaginal and anal sex (13%), and condom use problems were rarely explored (10%). Most forms documented STI/HIV counseling, although few (25%) included specific risk reduction plans.

CONCLUSIONS

Sexual histories are highly variable. Although challenging to accomplish, STI/HIV care, surveillance, and prevention may be improved by developing consensus on core questions to be used in sexual histories.

Sexual Risk, Nitrite Inhalant Use, and Lack of Circumcision Associated With HIV Seroconversion in Men Who Have Sex With Men in the United States

Men who have sex with men (MSM) continue to account for the largest number of new HIV infections in the United States, but limited data exist on independent risk factors for infection beyond the early 1990s. The HIV Network for Prevention Trials Vaccine Preparedness Study enrolled 3257 MSM in 6 US cities from 1995 to 1997. HIV seroincidence was 1.55 per 100 person-years (95% confidence interval: 1.23-1.95) over 18 months of follow-up. On multi-variable analysis using time-dependent covariates, independent risk factors for HIV seroconversion were increased number of reported HIV-negative male sex partners (adjusted odds ratio (AOR) = 1.14 per partner, population attributable risk (PAR) = 28%), nitrite inhalant use (AOR = 2.2, PAR = 28%), unprotected receptive anal sex with an HIV unknown serostatus partner (AOR = 2.7, PAR = 15%) or HIV-positive partner (AOR = 3.4, PAR = 12%), protected receptive anal sex with an HIV-positive partner (AOR = 2.2, PAR = 11%), lack of circumcision (AOR = 2.0, PAR = 10%), and receptive oral sex to ejaculation with an HIV-positive partner (AOR = 3.8, PAR = 7%). Having a large number of male sex partners, nitrite inhalant use, and engaging in receptive anal sex explained the majority of infections in this cohort and should be targeted in prevention strategies for MSM.

Sex behaviour of men who have sex with men and risk of HIV in Andhra Pradesh, India

OBJECTIVE

To obtain information on sex behaviour of a large sample of men who have sex with men (MSM) in India that would assist in planning HIV prevention.

METHODS

Homosexual/bisexual behaviour of 6661 MSM at 62 urban-rural locations of various sizes in the Indian state of Andhra Pradesh was assessed through detailed interview. Multivariate analyses were performed to understand the associations with unprotected penetrative sex and barriers to condom use assessed.

RESULTS

The average number of different male sex partners in past 4 weeks was six. In last three sex encounters with men, totalling 19 640, anal sex occurred in 16 769, at least once by 6121 (91.9%) MSM of which 3423 [55.9%; 95% confidence interval (CI), 51.7-60.1%] did not use condom at least once. A total of 2785 (41.8%) were currently married to women and 3354 (50.4%) had had vaginal/anal sex with women in the past 3 months, of which 2818 (84%; 95% CI, 81.1-86.9%) did not use a condom. Furthermore, 1585 (25.9%; 95% CI, 22.7-29.1%) had anal sex without a condom with men and also vaginal/anal sex without a condom with women. This was prevalent across urban-rural locations and its strongest association was with currently married MSM (odds ratio 15.1; 95% CI, 12.5-18.2). The predominant reason for not using a condom with women was 'do not use with regular partner' (68.4%).

CONCLUSION

This high rate of unprotected penetrative sex by MSM with both men and women suggests that HIV prevention efforts in India should include a focus on MSM as well as their wives across many urban-rural locations and not only in large cities.

Sexual behavior patterns of methamphetamine-using gay and bisexual men

We assessed the sexual behaviors of 49 gay and bisexual methamphetamine users in New York City and the relationship between their use of the substance and their sexual practices as part of a larger investigation of the behavioral aspects of methamphetamine use. Participants were assessed on their use of methamphetamine and their sexual behaviors in conjunction with use of the substance. Participants reported equivalent rates of unprotected anal insertive and receptive behaviors when comparing their sexual acts while high on methamphetamine, high on other drugs, and sober. In addition, equivalent rates of "extreme" sex acts were found for 10 of the 12 behaviors examined while high on methamphetamine and while sober. While wefound few differences in terms of rates of sexual behaviors, our analysis revealed more frequent risky sexual behaviors among HIV positive men when compared with HIV negative men. Our results suggest that methamphetamine attracts a hypersexual risk-taking group of men who engage in unprotected sexual behaviors regardless of their methamphetamine use. Treatment implications are discussed.

Correlates of sex trading among drug-using men who have sex with men

OBJECTIVES

We examined correlates of trading sex for money, drugs, and shelter, or food among drug-using men who have sex with men (MSM).

METHODS

Audio computer-assisted self-interviewing questionnaires were completed by 387 MSM. The association of predictors with sex trading was assessed with chi(2) tests and multiple logistic regression.

RESULTS

Sex-trading prevalence was 62.5% (95% confidence interval=57.7%, 67.4%). Sex trading was associated with crack use, injection drug use, childhood maltreatment, non-gay self-identification, and homelessness (adjusted odds ratios=3.72, 2.28, 2.62, 2.21, and 1.88, respectively).

CONCLUSIONS

Multiple risk factors are associated with sex trading among MSM. Interventions may need to address crack and injection drug use, homelessness, and childhood maltreatment and target non-gay-identified MSM who engage in sex trading.

Comparison of sexually transmitted disease prevalence by reported condom use: errors among consistent condom users seen at an urban sexually transmitted disease clinic

BACKGROUND

The protective effect of condom use is controversial as a result of limited data.

GOAL

The goal of this study was to assess the association between condom use errors in consistent condom users and the prevalence of various sexually transmitted diseases (STDs).

STUDY

We conducted a cross-sectional study of visits to an urban STD clinic between January 2001 and January 2003, by women, men who have sex with women (MSW), and men who have sex with men (MSM) by consistent condom users with or without a condom use error.

METHODS

Prevalence rates were calculated for gonorrhea, chlamydia, trichomonas, nongonococcal urethritis (NGU), and pelvic inflammatory disease. Rates were stratified by reported errors in condom use over the past 4 months for consistent users with adjusted odds ratios calculated by logistic regression.

RESULTS

Among 1973 consistent condom users with error information available, any condom use error was reported more commonly among women (57%) than MSW (48%), or MSM (P <0.001 for each comparison), with breakage being the most frequently reported error. Among MSW, having a condom use error was associated with gonorrhea (adjusted odds ratio [AOR], 5.53; 95% confidence interval [CI], 2.48-12.35), chlamydia (AOR, 3.19; 95% CI, 1.80-5.65), and NGU (AOR, 2.09; 95% CI, 1.45-3.01), whereas, for women and MSM, no associations were seen for any STD.

CONCLUSIONS

Condom use errors were common among subjects reporting consistent condom use and for MSW, condom error was associated with a significant increased risk of STD. These data support the premise that correctness of condom use is an important methodologic issue in studies assessing condom effectiveness.

Risk Factors for Rectal Gonococcal Infection Amidst Resurgence in HIV Transmission

BACKGROUND

Rectal gonorrhea in men has been increasing in San Francisco since 1995.

GOAL

The goal was to determine behavioral risk factors associated with rectal gonorrhea (RGC) among men who have sex with men (MSM) by HIV serostatus.

STUDY DESIGN

All men reporting receptive anal sex in the last 6 months are screened for RGC, regardless of reported condom use, at San Francisco's municipal sexually transmitted disease (STD) clinic. We surveyed a convenience sample of men screened for RGC at the clinic.

RESULTS

Among 564 MSM surveyed, 7.1% had RGC. HIV-positive MSM were significantly more likely (relative risk, 3.5, 95% confidence interval, 1.9-5.8) to have RGC. Behavioral risks for RGC infection varied significantly by HIV serostatus. HIV-positive MSM engaging in anonymous sex were at highest risk for RGC infection. Drug use during anal sex was the strongest risk factor for RGC infection among HIV-negative or unknown HIV status MSM.

CONCLUSION

Our data suggest that STD and HIV prevention efforts among MSM in San Francisco must consider the role that HIV serostatus plays in acquisition of new infections.
