Explaining disparities in HIV infection among black and white men who have sex with men: a meta-analysis of HIV risk behaviors

Health, trust, or "just understood": explicit and implicit condom decision-making processes among black, white, and interracial same-sex male couples

Among gay and bisexual men, primary partners are a leading source of HIV infection. Trust, intimacy, and advancements in HIV treatment may impact same-sex male (SSM) couples' decisions to engage in unprotected anal intercourse (UAI). This qualitative study explored how Black, White and interracial couples discussed, and made decisions regarding condoms. Qualitative interviews were conducted with 48 SSM couples in the New York and San Francisco metropolitan areas. Stratified purposive sampling was used to include Black (n = 16), White (n = 17), and interracial (Black-White) (n = 15) couples. Twenty-six couples were concordant HIV-negative and 22 were HIV-discordant. Interviews were recorded, transcribed, coded, and analyzed using a grounded theory approach. Some couples described explicit processes, which involved active discussion, while others described implicit processes, where condom-use decisions occurred without any explicit discussion. These processes also differed by race and HIV status. Black couples tended to report condom-use as "just understood." White, HIV-discordant couples decided not to use condoms, with some identifying the HIV-positive partner's suppressed viral load and high CD4 count as deciding factors. After an unplanned episode of UAI, White, HIV-negative couples tended to discontinue condom use while Black HIV-negative couples decided to revert to using condoms. HIV prevention efforts focused on same-sex, male couples must consider the explicit/implicit nature of condom decision-making processes. Understanding differences in these processes and considering relationship dynamics, across race and HIV status, can promote the development of innovative couple-level, HIV prevention interventions.

Racial differences in the validity of self-reported drug use among men who have sex with men in Atlanta, GA

BACKGROUND

Men who have sex with men (MSM), particularly young black MSM, are disproportionately affected in the United States' HIV epidemic. Drug use may contribute to these disparities, yet previous studies have failed to provide evidence of elevated use among black MSM, relying exclusively on self-reported usage. This study uses biological assays to validate self-reports of drug use and explore the potential for misclassification to distort findings on racial patterns of use in this population.

METHODS

From an Atlanta-based cohort study of 454 black and 349 white MSM from 2010 to 2012, participants' self-reported drug use was compared to urine drug screening findings. The sensitivity of self-report was calculated as the proportion reporting recent usage among those who screened positive. Multivariable regression models were constructed to examine racial patterns in self-report, urine-detection, and self-report sensitivity of marijuana and cocaine usage, adjusted for socio-demographic factors.

RESULTS

In analyses that adjusted for age, education, income, sexual orientation, and history of arrest, black MSM were less likely to report recent use of marijuana (P<0.001) and cocaine (P=0.02), but equally likely to screen positive for either drug. This discrepancy between self-reported and urine-detected drug use was explained by significantly lower sensitivity of self-report for black participants (P<0.001 for marijuana, P<0.05 for cocaine).

CONCLUSIONS

The contribution of individual drug-related risk behaviors to the HIV disparities between black and white MSM should be revisited with methods that validate self-reports of illegal drug use.

Peer social support is associated with recent HIV testing among young black men who have sex with men

Resiliency factors such as social support have been associated with more frequent HIV testing among MSM. We examined the association between social support and delayed HIV testing in the context of structural discrimination and individual factors among young Black MSM. We combined two independent cross-sectional samples recruited 1 year apart from a venue-based, modified time-location sampling study of young Black MSM aged 18-29 years in the US South. Our subsample (N = 813) was men who self-reported not being HIV positive and who indicated they had one or more male sex partners in the past 2 months. Using a social epidemiology framework we estimated associations of structural (racism and homophobia), social (social support from other Black MSM friends) and individual factors with delayed HIV testing (>6 months ago) using logistic regression. Bivariate analyses demonstrated that individual level variables as well as experiences of racism (OR 1.20, 95% CI 1.02-1.41) and homophobia (OR 1.49, 95 % CI 1.02-2.17) were associated with higher risk of delayed HIV testing. Receiving social support from other Black MSM friends was associated with lower risk of delayed HIV testing (OR 0.80, 95 % CI 0.67-0.95). In multivariable models, social support remained significantly associated with lower risk of delayed HIV testing after inclusion of structural and individual level variables. Social support has a positive and robust association with HIV testing among young Black MSM. Whether community building and development of resiliency factors can overcome structural, social, and individual-level barriers to HIV prevention and care for young Black MSM warrants further study.

Utilization of HIV prevention services across racial/ethnic groups among men who have sex with men in San Francisco, California, 2008

Human Immunodeficiency Virus (HIV) infection in the US is disproportionally higher among Black and Latino men who have sex with men (MSM), compared to other racial/ethnic groups. The 2008 US National HIV Behavioral Surveillance (NHBS) survey of MSM was analyzed to compare utilization of HIV testing, receiving condoms, and individual and group HIV prevention programs among racial/ethnic groups in San Francisco, CA. Using a weighted analysis of the time-location sampling method, racial/ethnic subpopulation estimates were obtained for utilization of these services in the prior 12 months. There was no significant difference in utilization of HIV prevention services among Black (N=37), Latino (N=128), and White (N=275) MSM in San Francisco, CA. Overall 60-70 % of MSM reported their last HIV test within the past 12 months and more than 75 % reported receiving condoms in the last 12 months. However, less than 15 % of MSM reported utilizing individual or group HIV prevention counseling sessions. The NHBS survey demonstrate that the majority of MSM in San Francisco, CA have utilized one or more HIV prevention service in the past 12 months and that there were no racial/ethnic disparities in utilization of these services. However, the utilization of individual or group HIV prevention programs is low and HIV testing is below current recommendations for MSM.

Adapting the VOICES HIV behavioral intervention for Latino men who have sex with men

Latino men who have sex with men (MSM) are disproportionately impacted by HIV/AIDS, but few behavioral interventions address their prevention needs. Adaptation of evidence-based interventions is a pragmatic strategy that builds upon lessons learned and has the potential to fill gaps in prevention programming. Yet there are few reports of how transfers are executed and whether effectiveness is achieved. This research reports on the adaptation of VOICES/VOICES, a single-session intervention designed for heterosexual adults, into No Excuses/Sin buscar excuses for Latino MSM. To test the adapted intervention, 370 at-risk Latino MSM were enrolled in a randomized trial. At a three-month follow-up, there was a sharper decrease in unprotected intercourse in the intervention group compared to controls (59 % vs. 39 %, ANOVA p < 0.05, F = 4.10). Intervention participants also reported more condom use at last intercourse (AOR = 1.69; 95 % CI 1.02-2.81, p < 02). Findings support use of adapted models for meeting prevention needs of high-priority populations.

Age, race/ethnicity, and behavioral risk factors associated with per contact risk of HIV infection among men who have sex with men in the United States

OBJECTIVE

Young men who have sex with men (MSM) and MSM of color have the highest HIV incidence in the United States. To explore possible explanations for these disparities and known individual risk factors, we analyzed the per contact risk (PCR) of HIV seroconversion in the early highly active antiretroviral therapy era.

METHODS

Data from 3 longitudinal studies of MSM (HIV Network for Prevention Trials Vaccine Preparedness Study, EXPLORE behavioral efficacy trial, and VAX004 vaccine efficacy trial) were pooled. The analysis included visits where participants reported unprotected receptive anal intercourse (URA), protected receptive anal intercourse, or unprotected insertive anal intercourse (UIA) with an HIV seropositive, unknown HIV serostatus, or an HIV seronegative partner. We used regression standardization to estimate average PCRs for each type of contact, with bootstrap confidence intervals.

RESULTS

The estimated PCR was highest for URA with an HIV seropositive partner (0.73%; 95% bootstrap confidence interval [BCI]: 0.45% to 0.98%) followed by URA with a partner of unknown HIV serostatus (0.49%; 95% BCI: 0.32% to 0.62%). The estimated PCR for protected receptive anal intercourse and UIA with an HIV seropositive partner was 0.08% (95% BCI: 0.0% to 0.19%) and 0.22% (95% BCI: 0.05% to 0.39%), respectively. Average PCRs for URA and UIA with HIV seropositive partners were higher by 0.14%-0.34% among younger participants and higher by 0.08% for UIA among Latino participants compared with white participants. Estimated PCRs increased with the increasing number of sexual partners, use of methamphetamines or poppers, and history of sexually transmitted infection.

CONCLUSIONS

Susceptibility or partner factors may explain the higher HIV conversion risk for younger MSM, some MSM of color, and those reporting individual risk factors.

Understanding racial HIV/STI disparities in black and white men who have sex with men: a multilevel approach

Background

The reasons for black/white disparities in HIV epidemics among men who have sex with men have puzzled researchers for decades. Understanding reasons for these disparities requires looking beyond individual-level behavioral risk to a more comprehensive framework.

Methods and Findings

From July 2010-Decemeber 2012, 803 men (454 black, 349 white) were recruited through venue-based and online sampling; consenting men were provided HIV and STI testing, completed a behavioral survey and a sex partner inventory, and provided place of residence for geocoding. HIV prevalence was higher among black (43%) versus white (13% MSM (prevalence ratio (PR) 3.3, 95% confidence interval (CI): 2.5–4.4). Among HIV-positive men, the median CD4 count was significantly lower for black (490 cells/µL) than white (577 cells/µL) MSM; there was no difference in the HIV RNA viral load by race. Black men were younger, more likely to be bisexual and unemployed, had less educational attainment, and reported fewer male sex partners, fewer unprotected anal sex partners, and less non-injection drug use. Black MSM were significantly more likely than white MSM to have rectal chlamydia and gonorrhea, were more likely to have racially concordant partnerships, more likely to have casual (one-time) partners, and less likely to discuss serostatus with partners. The census tracts where black MSM lived had higher rates of poverty and unemployment, and lower median income. They also had lower proportions of male-male households, lower male to female sex ratios, and lower HIV diagnosis rates.

Conclusions

Among black and white MSM in Atlanta, disparities in HIV and STI prevalence by race are comparable to those observed nationally. We identified differences between black and white MSM at the individual, dyadic/sexual network, and community levels. The reasons for black/white disparities in HIV prevalence in Atlanta are complex, and will likely require a multilevel framework to understand comprehensively.

"I didn't think I could get out of the fucking park." Gay men's retrospective accounts of neighborhood space, emerging sexuality and migrations

Young, African American and Latino gay, bisexual and other men who have sex with men (MSM) are disproportionately represented among new HIV cases according to the most recent national surveillance statistics. Analysts have noted that these racial/ethnic disparities in HIV among MSM exist within the wider context of sexual, mental and physical health disparities between MSM and heterosexuals. The intercorrelation of these adverse health outcomes among MSM, termed syndemics, has been theorized to be socially produced by a heterosexist social system that marginalizes lesbian, gay, bisexual, MSM and other sexual minorities. African American and Latino MSM experience overlapping systems of oppression that may increase their risk of experiencing syndemic health outcomes. In this paper, using data from twenty in-depth qualitative interviews with MSM living in four New York City (NYC) neighborhoods, we present accounts of neighborhood space, examining how space can both physically constitute and reinforce social systems of stratification and oppression, which in turn produce social disparities in sexual health outcomes. By analyzing accounts of emerging sexuality in neighborhood space, i.e. across time and space, we identify pathways to risk and contribute to our understanding of how neighborhood space is experienced by gay men, adding to our ability to support young men as they emerge in place and to shape the social topography of urban areas.

Structural bridging network position is associated with HIV status in a younger Black men who have sex with men epidemic

Younger Black men who have sex with men (BMSM) ages 16-29 have the highest rates of HIV in the United States. Despite increased attention to social and sexual networks as a framework for biomedical intervention, the role of measured network positions, such as bridging and their relationship to HIV risk has received limited attention. A network sample (N = 620) of BMSM respondents (N = 154) and their MSM and transgendered person network members (N = 466) was generated through respondent driven sampling of BMSM and elicitation of their personal networks. Bridging status of each network member was determined by a constraint measure and was used to assess the relationship between this bridging and unprotected anal intercourse (UAI), sex-drug use (SDU), group sex (GS) and HIV status within the network in South Chicago. Low, moderate and high bridging was observed in 411 (66.8 %), 81 (13.2 %) and 123 (20.0 %) of the network. In addition to age and having sex with men only, moderate and high levels of bridging were associated with HIV status (aOR 3.19; 95 % CI 1.58-6.45 and aOR 3.83; 95 % CI 1.23-11.95, respectively). Risk behaviors observed including UAS, GS, and SDU were not associated with HIV status, however, they clustered together in their associations with one another. Bridging network position but not risk behavior was associated with HIV status in this network sample of younger BMSM. Socio-structural features such as position within the network may be important when implementing effective HIV prevention interventions in younger BMSM populations.

Concomitant socioeconomic, behavioral, and biological factors associated with the disproportionate HIV infection burden among Black men who have sex with men in 6 U.S. cities

BACKGROUND

American Black men who have sex with men (MSM) are disproportionately affected by HIV, but the factors associated with this concentrated epidemic are not fully understood.

METHODS

Black MSM were enrolled in 6 US cities to evaluate a multi-component prevention intervention, with the current analysis focusing on the correlates of being newly diagnosed with HIV compared to being HIV-uninfected or previously diagnosed with HIV.

RESULTS

HPTN 061 enrolled 1553 Black MSM whose median age was 40; 30% self-identified exclusively as gay or homosexual, 29% exclusively as bisexual, and 3% as transgender. About 1/6(th) (16.2%) were previously diagnosed with HIV (PD); of 1263 participants without a prior HIV diagnosis 7.6% were newly diagnosed (ND). Compared to PD, ND Black MSM were younger (p<0.001); less likely to be living with a primary partner (p<0.001); more likely to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.011) or chlamydia (p = 0.020). Compared to HIV-uninfected Black MSM, ND were more likely to report unprotected receptive anal intercourse (URAI) with a male partner in the last 6 months (p<0.001); and to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.004), and urethral (p = 0.025) or rectal chlamydia (p<0.001). They were less likely to report female (p = 0.002) or transgender partners (p = 0.018). Multivariate logistic regression analyses found that ND Black MSM were significantly more likely than HIV-uninfected peers to be unemployed; have STIs, and engage in URAI. Almost half the men in each group were poor, had depressive symptoms, and expressed internalized homophobia.

CONCLUSIONS

ND HIV-infected Black MSM were more likely to be unemployed, have bacterial STIs and engage in URAI than other Black MSM. Culturally-tailored programs that address economic disenfranchisement, increase engagement in care, screen for STIs, in conjunction with safer sex prevention interventions, may help to decrease further transmission in this heavily affected community.

Disparities in HIV transmission risk among HIV-infected black and white men who have sex with men, United States, 2009

OBJECTIVE

To better understand why HIV incidence is substantially higher among black than white men who have sex with men (MSM), we present the first nationally representative estimates of factors that contribute to transmission - sexual behavior, antiretroviral therapy (ART) use, and viral suppression - among HIV-infected black and white MSM in the United States.

DESIGN

The Medical Monitoring Project (MMP) is a complex sample survey of HIV-infected adults receiving medical care in the United States.

METHODS

We used weighted interview and medical record data collected during June 2009 to May 2010 to estimate the prevalence of sexual behaviors, ART use, and viral suppression among sexually active HIV-infected black and white MSM. We used χ tests to assess significant differences between races and logistic regression models to identify factors that mediated the racial differences.

RESULTS

Sexual risk behaviors among black and white MSM were similar. Black MSM were significantly less likely than white MSM to take ART (80 vs. 91%) and be durably virally suppressed (48 vs. 69%). Accounting for mediators (e.g. age, insurance, poverty, education, time since diagnosis, and disease stage) reduced, but did not eliminate, disparities in ART use and rendered differences in viral suppression among those on ART insignificant.

CONCLUSION

Lower levels of ART use and viral suppression among HIV-infected black MSM may increase the likelihood of HIV transmission. Addressing the patient-level factors and structural inequalities that contribute to lower levels of ART use and viral suppression among this group will improve clinical outcomes and might reduce racial disparities in HIV incidence.

Situational, partner, and contextual factors associated with level of risk at most recent intercourse among Black men who have sex with men

African American men who have sex with men (MSM) in the United States bear a disproportionate burden of HIV infection and disease incidence. 178 Black MSM provided detailed situational information concerning their most recent act of anal intercourse (AI) with a male partner including condom use, partner characteristics, serostatus disclosure, and substance use. Participants completed scales assessing AIDS-related as well as broader contextual domains. Most recent AI acts occurred with same-race partners outside of main relationships. Over one-third of AI acts were unprotected, and almost half of the unprotected acts were not between known HIV-concordant partners. Nearly half of men reported substance use before sex. In a multiple regression analysis, unprotected AI with a partner not known to be concordant was predicted by low risk reduction intentions and indicators of a casual relationship. The findings highlight issues and partner contexts associated with risk for contracting HIV infection among Black MSM.

HIV among Black men who have sex with men (MSM) in the United States: a review of the literature

In 2006, Millett published a seminal literature review that examined 12 hypotheses to explain the high rates of HIV among black MSM. This paper augments Millett's article by reviewing the recent literature on behavioral, biomedical, structural, social contextual, psychosocial, and social network factors that affect HIV rates among black MSM. We searched three databases: PubMed, Scopus, and Google Scholar. First we searched all articles that included black or African American and MSM and HIV. We then searched the following terms for each area: behavioral (drug use during sex, crack cocaine use, and serosorting); biomedical (circumcision, STDs, and STIs); structural (access to care, HIV care, ART, HAART, patient-provider communication, HIV quality of care); social contextual (stigma, discrimination, internalized homophobia, internalized heterosexism, medical mistrust, social isolation, and incarceration); psychosocial (peer support and mental health); and social network (sexual mixing, partner characteristics, and social networks) factors. We identified 39 articles to include in this review. We found inconclusive evidence that incarceration, stigma, discrimination, social isolation, mental health disparities, or social networks explain the elevated rates of HIV among black MSM. We found evidence that the differences in rates of HIV between black and white MSM may be explained by differences in STIs, undiagnosed seropositivity, access to care and treatment services, and use of HAART. There is an overwhelming need for HIV testing, linkage to care, retention in care, and adherence programs for black MSM.

Epidemiology of HIV among female sex workers, their clients, men who have sex with men and people who inject drugs in West and Central Africa

Introduction

The West and Central Africa (WCA) sub-region is the most populous region of sub-Saharan Africa (SSA), with an estimated population of 356 million living in 24 countries. The HIV epidemic in WCA appears to have distinct dynamics compared to the rest of SSA, being more concentrated among key populations such as female sex workers (FSWs), men who have sex with men (MSM), people who inject drugs (PWID) and clients of FSWs. To explore the epidemiology of HIV in the region, a systematic review of HIV literature among key populations in WCA was conducted since the onset of the HIV epidemic.

Methods

We searched the databases PubMed, CINAHL and others for peer-reviewed articles regarding FSWs, MSM and PWID in 24 countries with no date restriction. Inclusion criteria were sensitive and focused on inclusion of any HIV prevalence data among key populations. HIV prevalence was pooled, and in each country key themes were extracted from the literature.

Results

The search generated 885 titles, 214 abstracts and 122 full articles, of which 76 met inclusion and exclusion criteria providing HIV prevalence data. There were 60 articles characterizing the burden of disease among FSWs, eight for their clients, one for both, six for MSM and one for PWID. The pooled HIV prevalence among FSWs was 34.9% (n=14,388/41,270), among their clients was 7.3% (n=435/5986), among MSM was 17.7% (n=656/3714) and among PWID from one study in Nigeria was 3.8% (n=56/1459).

Conclusions

The disproportionate burden of HIV among FSWs appears to be consistent from the beginning of the HIV epidemic in WCA. While there are less data for other key populations such as clients of FSWs and MSM, the prevalence of HIV is higher among these men compared to other men in the region. There have been sporadic reports among PWID, but limited research on the burden of HIV among these men and women. These data affirm that the HIV epidemic in WCA appears to be far more concentrated among key populations than the epidemics in Southern and Eastern Africa. Evidence-based HIV prevention, treatment and care programmes in WCA should focus on engaging populations with the greatest burden of disease in the continuum of HIV care.

Differences in substance use, psychosocial characteristics and HIV-related sexual risk behavior between Black men who have sex with men only (BMSMO) and Black men who have sex with men and women (BMSMW) in six US cities

We assessed associations in substance use, psychosocial characteristics, and HIV-related sexual risk behaviors, comparing characteristics of Black men who only have sex with other men only (BMSMO; n = 839) to Black men who have sex with men and women (BMSMW; n = 590). The study analyzed baseline data from the HIV Prevention Trials Network Brothers Study (HPTN 061), a feasibility study of a multi-component intervention for Black MSM in six US cities. Bivariate analyses compared BMSMO to BMSMW along demographics, substance use, psychosocial characteristics, and HIV-related sexual risk behaviors. Logistic regression models then assessed multivariable associations between being BMSMW and the odds of engaging in HIV-related sexual risk behaviors. Adjusted analyses revealed that BMSMW remained more likely to have unprotected anal intercourse while under the influence of alcohol (AOR: 1.45; 95 % CI:1.11-1.90) and were more likely to receive money/drugs for sex (AOR: 2.11; 95 % CI:1.48-3.03), compared to BMSMO. Substance use is an important factor to be considered when developing risk-reduction interventions for BMSMW. Structural interventions that address factors that may contribute to exchange sex among these men are also warranted.

Intergenerational sex as a risk factor for HIV among young men who have sex with men: a scoping review

An emerging body of evidence suggests that intergenerational sexual partnerships may increase risk of HIV acquisition among young men who have sex with men (YMSM). However, no studies have comprehensively evaluated literature in this area. We applied a scoping review methodology to explore the relationships between age mixing, HIV risk behavior, and HIV seroconversion among YMSM. This study identified several individual, micro-, and meso-system factors influencing HIV risk among YMSM in the context of intergenerational relationships: childhood maltreatment, coming of age and sexual identity, and substance use (individual-level factors); family and social support, partner characteristics, intimate partner violence, connectedness to gay community (micro-system factors); and race/ethnicity, economic disparity, and use of the Internet (meso-system factors). These thematic groups can be used to frame future research on the role of age-discrepant relationships on HIV risk among YMSM, and to enhance public health HIV education and prevention strategies targeting this vulnerable population.

Hypermasculinity and Sexual Risk Among Black and White Men Who Have Sex With Men and Women

Men who have sex with men and women (MSMW), particularly Black MSMW, are at high risk for HIV. However, few studies have focused on factors that influence Black MSMW’s specific HIV risk behaviors, and there are no evidence-based interventions specifically targeting this population. Some studies have suggested that masculine ideals are associated with high-risk sex practices and partners. Norms around masculinity in the social environments in which MSMW live may prohibit nonheterosexual identities and behaviors, may lead to internalized homophobia, and may promote high-risk strategies to seek male partners. Using data collected from 180 Black and 101 White MSMW recruited for a study to develop strategies for recruiting MSMW for research and services and to inform the content of HIV prevention messages, we examined the association between hypermasculinity ideals and sexual behaviors that may contribute to increased HIV risk among Black MSMW and a comparison group of White MSMW. Comparing Black and White MSMW, we explored how this association may differ by race. Multivariate models, controlling for sociodemographic and other covariates, indicate that hypermasculine ideals are associated with increased numbers of male and female partners among Black MSMW and an increased number of female partners among White MSMW. Hypermasculinity is important to address in programs that aim to reduce HIV risk among Black MSMW.

The increase in global HIV epidemics in MSM

Epidemics of HIV in MSM continue to expand in most low, middle, and upper income countries in 2013 and rates of new infection have been consistently high among young MSM. Current prevention and treatment strategies are insufficient for this next wave of HIV spread. We conducted a series of comprehensive reviews of HIV prevalence and incidence, risks for HIV, prevention and care, stigma and discrimination, and policy and advocacy options. The high per act transmission probability of receptive anal intercourse, sex role versatility among MSM, network level effects, and social and structural determinants play central roles in disproportionate disease burdens. HIV can be transmitted through large MSM networks at great speed. Molecular epidemiologic data show marked clustering of HIV in MSM networks, and high proportions of infections due to transmission from recent infections. Prevention strategies that lower biological risks, including those using antiretrovirals, offer promise for epidemic control, but are limited by structural factors including, discrimination, criminalization, and barriers to healthcare. Subepidemics, including among racial and ethnic minority MSM in the United States and UK, are particularly severe and will require culturally tailored efforts. For the promise of new and combined bio-behavioral interventions to be realized, clinically competent healthcare is necessary and community leadership, engagement, and empowerment are likely to be key. Addressing the expanding epidemics of HIV in MSM will require continued research, increased resources, political will, policy change, structural reform, community engagement, and strategic planning and programming, but it can and must be done.

Sexual risk behavior among HIV-uninfected men who have sex with men participating in a tenofovir preexposure prophylaxis randomized trial in the United States

OBJECTIVE

To evaluate for changes in sexual behaviors associated with daily pill use among men who have sex with men (MSM) participating in a preexposure prophylaxis trial.

DESIGN

Randomized, double-blind, placebo-controlled trial. Participants were randomized 1:1:1:1 to receive tenofovir disoproxil fumarate or placebo at enrollment or after a 9-month delay and followed for 24 months.

METHODS

Four hundred HIV-negative MSM reporting anal sex with a man in the past 12 months and meeting other eligibility criteria enrolled in San Francisco, Atlanta, and Boston. Sexual risk was assessed at baseline and quarterly visits using Audio Computer-Assisted Self-Interview. The association of pill taking with sexual behavior was evaluated using logistic and negative-binomial regressions for repeated measures.

RESULTS

Overall indices of behavioral risk declined or remained stable during follow-up. Mean number of partners and proportion reporting unprotected anal sex declined during follow-up (P < 0.05), and mean unprotected anal sex episodes remained stable. During the initial 9 months, changes in risk practices were similar in the group that began pills immediately vs. those in the delayed arm. These indices of risk did not differ significantly after initiation of pill use in the delayed arm or continuation of study medication in the immediate arm. Use of poppers, amphetamines, and sexual performance-enhancing drugs were independently associated with one or more indices of sexual risk.

CONCLUSIONS

There was no evidence of risk compensation among HIV-uninfected MSM in this clinical trial. Monitoring for risk compensation should continue now that preexposure prophylaxis has been shown to be efficacious in MSM and other populations and will be provided in open-label trials and other contexts.

Anal sex role segregation and versatility among men who have sex with men: EXPLORE Study

Anal sex role patterns and correlates during unprotected anal sex were examined longitudinally among HIV-negative men who have sex with men. Nearly 9.6% were exclusively receptive, 16.7% exclusively insertive, and 63.0% versatile. Versatility was more likely with primary and HIV-negative/unknown status partners and among younger men and substance users but less likely among Blacks and with higher number of partners. Exclusively receptive role was more likely with HIV-negative/unknown status partners and among younger men and substance users but less likely with higher number of partners. Examining anal sex role patterns helps understand the factors that drive the epidemic among men who have sex with men.

Methamphetamine and other substance use trends among street-recruited men who have sex with men, from 2008 to 2011

BACKGROUND

It is particularly important to survey substance use trends in populations most impacted by the consequences of substance use. Men who have sex with men (MSM) exhibit rates of methamphetamine and other substance use that exceeds those observed among other populations in the United States. Such substance use has been associated with numerous negative health sequelae.

METHODS

An outreach program performed street encounters with 5599 unique substance-using MSM from January 1, 2008 through December 31, 2011 to collect data on self-reported sociodemographics and recent substance use. Data were aggregated into six-month cohorts for comparisons of recent substance use patterns across time

RESULTS

Participants averaged 33 years of age (SD=8), most were Caucasian/white (47%) or Hispanic/Latino (32%), and the self-reported HIV seroprevalence rate was 13.4%. Across cohorts, reported use of alcohol (range=91-93%), marijuana (range=36-46%), and/or methamphetamine (range=23-27%) was common; prevalence of amyl nitrite (max=14%), ecstasy (max=12%), powder cocaine (max=8%) and/or crack cocaine (max=4%) use, although less common, were still elevated relative to the United States general population.

CONCLUSIONS

Methamphetamine and other substance use remained common among substance-using MSM, demonstrating the need for continued substance use interventions geared toward this high-risk population.

"You're an open target to be abused": a qualitative study of stigma and HIV self-disclosure among Black men who have sex with men

The HIV/AIDS epidemic is a health crisis among Black men who have sex with men (MSM). HIV-related stigma presents a primary barrier to sexual communication and effective HIV prevention. Using in-depth, qualitative interviews conducted with 20 HIV-positive Black MSM between 2007 and 2008 in Chicago, Illinois, we explored the themes related to HIV-related stigma and the underlying messages HIV-positive Black MSM receive regarding their status. Stigmatizing messages stem from family, churches, and the gay community and from negative, internalized, beliefs HIV-positive Black MSM held about infected individuals before their own infection. HIV stigma influences sexual silence around HIV disclosure, especially to sexual partners.

Lessons learned from use of social network strategy in HIV testing programs targeting African American men who have sex with men

OBJECTIVES

We report lessons derived from implementation of the Social Network Strategy (SNS) into existing HIV counseling, testing, and referral services targeting 18- to 64-year-old Black gay, bisexual, and other men who have sex with men (MSM).

METHODS

The SNS procedures used in this study were adapted from a Centers for Disease Control and Prevention-funded, 2-year demonstration project involving 9 community-based organizations (CBOs) in 7 cities. Under the SNS, HIV-positive and HIV-negative men at high risk for HIV (recruiters) were enlisted to identify and recruit persons from their social, sexual, or drug-using networks (network associates) for HIV testing. Sites maintained records of modified study protocols for ascertaining lessons learned. The study was conducted between April 2008 and May 2010 at CBOs in Washington, DC, and New York, New York, and at a health department in Baltimore, Maryland.

RESULTS

Several common lessons regarding development of the plan, staffing, training, and use of incentives were identified across the sites. Collectively, these lessons indicate use of SNS is resource-intensive, requiring a detailed plan, dedicated staff, and continual input from clients and staff for successful implementation.

CONCLUSIONS

SNS may provide a strategy for identifying and targeting clusters of high-risk Black MSM for HIV testing. Given the resources needed to implement the strategy, additional studies using an experimental design are needed to determine the cost-effectiveness of SNS compared with other testing strategies.

HIV testing patterns among black men who have sex with men: a qualitative typology

BACKGROUND

Black men who have sex with men (MSM) in the Southeastern United States are disproportionately affected by HIV. Black MSM are more likely to have unrecognized HIV infection, suggesting that testing may occur later and/or infrequently relative to current recommendations. The objective of this qualitative study was to explore the HIV testing behaviors of Black MSM in Atlanta, Georgia, who were participants in the HIV Prevention Trials Network Brothers Study (HPTN 061).

METHODS AND FINDINGS

We conducted 29 in-depth interviews and four focus groups with a community-recruited sample. Modified grounded theory methodologies were used to guide our inductive analysis, which yielded a typology comprised of four distinct HIV testing patterns. Participants could be categorized as: (1) Maintenance Testers, who tested regularly as part of routine self-care; (2) Risk-Based Testers, whose testing depended on relationship status or sexual behavior; (3) Convenience Testers, who tested irregularly depending on what testing opportunities arose; or (4) Test Avoiders, who tested infrequently and/or failed to follow up on results. We further characterized these groups with respect to age, socioeconomic factors, identity, stigma and healthcare access.

CONCLUSIONS

Our findings highlight the heterogeneity of HIV testing patterns among Black MSM, and offer a framework for conceptualizing HIV testing in this group. Public health messaging must account for the diversity of Black MSM's experiences, and multiple testing approaches should be developed and utilized to maximize outreach to different types of testers.

The implications of respondent concurrency on sex partner risk in a national, web-based study of men who have sex with men in the United States

BACKGROUND

Men who have sex with men (MSM) represent the largest HIV risk group in the United States. Sexual concurrency catalyzes HIV transmission in populations by increasing the indirect exposure of one's sex partners to one another. Although individual-level (egocentric) designs have demonstrated a high prevalence of concurrency among MSM respondents, methods are lacking for understanding the exposure implications for partners (dyads) reported in such studies.

METHODS

A new technique for manipulating egocentrically collected partnership timing data to measure the degree to which respondents' patterns of concurrency and serial monogamy resulted in the indirect exposure of respondents' partners to other partners was developed. Two outcomes were constructed for each partner: any concurrent or serially monogamous exposure to another partner (any exposure) and any concurrent exposure to another partner, irrespective of serial monogamy (any concurrent exposure). Reports of unprotected anal intercourse (UAI) were incorporated to construct the outcomes of 'any UAI exposure' and 'any concurrent UAI exposure.' This method was applied to an online study of MSM aged ≥18 years, with comparisons made by partner's race-ethnicity, age, type, and meeting location.

RESULTS

Among 4060 repeat partners of 2449 MSM, 73% had any exposure in the previous 6 months; 58% had any concurrent exposure. Among UAI partners, 37% had concurrent UAI exposure. Black UAI partners were more likely than whites to have any concurrent UAI exposure [unadjusted odds ratio (95% confidence interval) = 1.34 (1.05 to 1.70)], as were casual UAI partners relative to main partners [unadjusted odds ratio (95% confidence interval) = 4.37 (3.58 to 5.35)]. In adjusted models, black UAI partners were significantly more likely to have any UAI exposure, but not concurrent UAI exposure. Casual UAI partners remained more exposed by both outcomes.

CONCLUSIONS

Sex partners of MSM, particularly casual and black non-Hispanic partners, face a high degree of exposure to other partners.

Childhood sexual experiences among substance-using non-gay identified Black men who have sex with men and women

This study explored potential variations in childhood sexual abuse (CSA) by examining qualitative accounts of first sexual experiences among non-disclosing, non-gay identified Black men who have sex with men and women (MSMW). We analyzed data from semi-structured qualitative interviews with 33 MSMW who described first sexual experiences with male and female partners. Thematic analysis revealed four patterns of first sexual experiences including: unwanted sexual experiences with a male or female consistent with definitions of childhood sexual abuse; consensual sex with an older male or female; bodily exploration with another male or female child; and consensual sex with a peer-age female. Most of the experiences described by participants as consensual with an older male or female, however, met criteria for childhood sexual abuse found in the extant literature. Several men discussed childhood sexual experiences (CSE) relative to their experiences with alcohol, drugs, and same-sex behavior as adults. Findings suggest that the relationship between CSE and risk-taking behavior may be shaped by whether men perceive their experiences as abusive or consensual, and have implications for researchers, treatment providers and counselors.

Network analysis among HIV-infected young black men who have sex with men demonstrates high connectedness around few venues

BACKGROUND

Network analysis is useful for understanding sexual transmission of HIV and other sexually transmitted infections. We conducted egocentric and affiliation network analysis among HIV-infected young black men who have sex with men (MSM) in the Jackson, Mississippi, area to understand networks and connectedness of this population.

METHODS

We interviewed 22 black MSM aged 17 to 25 years diagnosed as having HIV in 2006 to 2008. Participants provided demographic and geographic information about each sex partner during the 12 months before diagnosis and identified venues where they met these partners. We created affiliation network diagrams to understand connectedness of this population and identify venues that linked participants.

RESULTS

The median number of partners reported was 4 (range, 1-16); a total of 97 partners (88 of whom were male) were reported. All but 1 participant were connected through a network of venues where they had met partners during the 12 months before diagnosis. Three venues were named as places for meeting partners by 13 of 22 participants. Participants reported having partners from all regions of Mississippi and 5 other states.

CONCLUSIONS

HIV-infected young black MSM in this analysis were linked by a small number of venues. These venues should be targeted for testing and prevention interventions. The pattern of meeting sex partners in a small number of venues suggests densely connected networks that propagate infection. This pattern, in combination with sexual partnerships with persons from outside Jackson, may contribute to spread of HIV and other sexually transmitted infections into or out the Jackson area.

A systematic review of HIV interventions for black men who have sex with men (MSM)

Background

Black men who have sex with men (MSM) are disproportionately burdened by HIV/AIDS. Despite this burden there has been a shortage of research on HIV interventions for black MSM. This article provides a comprehensive review of the literature on interventions for black MSM to identify effective HIV prevention intervention strategies for black MSM.

Methods

We searched 3 databases: Pubmed, Scopus, and Google Scholar to identify peer-reviewed articles and used the following search terms: African American or black; MSM or men who have sex with men and women (MSMW); HIV; program or intervention; and evaluation or intervention science or implementation research. We included research articles that assessed interventions for black men who have sex with men. We included studies that used an experimental, quasi-experimental, or pre-post test design as well as formative research studies. We also searched the CDC and NIH websites to identify planned and on-going intervention studies. We identified a total of 23 studies to include in the review.

Results

We identified 12 completed studies of interventions for black MSM. Eight of these 12 interventions aimed to reduce HIV risk behaviors and 5 found a significant reduction in HIV risk behavior over time. We identified 4 health service intervention studies for young black MSM.

Conclusions

Behavior change interventions are effective at reducing HIV risk behaviors among black MSM. However, relying only on behavioral interventions that aim to reduce HIV risk behavior will most likely not have a population-level effect on HIV infection among black MSM. There is a compelling and urgent need to develop and test comprehensive HIV testing, linkage to care, retention in care and adherence interventions for black MSM.

Disparities in engagement in care and viral suppression among persons with HIV

BACKGROUND

Engagement across the spectrum of HIV care can improve health outcomes and prevent HIV transmission. We used HIV surveillance data to examine these outcomes.

METHODS

San Francisco residents who were diagnosed with HIV between 2009 and 2010 were included. We measured the characteristics and proportion of persons linked to care within 6 months of diagnosis, retained in care for second and third visits, and virally suppressed within 12 months of diagnosis.

RESULTS

Of 862 persons included, 750 (87%) entered care within 6 months of diagnosis; of these, 72% had a second visit in the following 3-6 months; and of these, 80% had a third visit in the following 3-6 months. Viral suppression was achieved in 50% of the total population and in 76% of those retained for 3 visits. Lack of health insurance and unknown housing status were associated with not entering care (P < 0.01). Persons with unknown insurance status were less likely to be retained for a second visit; those younger than 30 years were less likely to be retained for a third visit. Independent predictors of failed viral suppression included age <40 years, homelessness, unknown housing status, and having a single or 2 medical visits compared with 3 visits.

CONCLUSIONS

Socioeconomic resources and age, not race or gender, are associated with disparities in engagement in HIV care in San Francisco.

HIV/AIDS disparity between African-American and Caucasian men who have sex with men: intervention strategies for the black church

This manuscript examines the HIV/AIDS health disparity among African-American (AA) men who have sex with men (MSM) as compared to non-Hispanic White (NHW) MSM, and proposes faith-based intervention strategies as a means of reducing the disparity. Effective faith-based HIV/AIDS intervention programs to encompass AA MSM must include community-based participatory research; engage the faith community through data sharing; specifically target and equip church leaders in addition to laity; involve effective collaboration and compromise between public health practitioners and faith leaders; emphasize spirituality and compassion; utilize popular opinion leaders; and be intergenerational.

HIV transmission in the United States: considerations of viral load, risk behavior, and health disparities

Ongoing HIV transmission is related to prevalence, risk behavior and viral load among persons with HIV. We assessed the contribution of these factors to HIV transmission with transmission rate models and data reported to National HIV Surveillance and published rates of risk behavior. We also estimated numbers of persons with risk behaviors and unsuppressed viral load among sexual risk groups. The transmission rate is higher considering risk behavior (18.5 infections per 100 people with HIV) than that attributed to unsuppressed viral load (4.6). Since persons without risk behavior or suppressed viral load presumably transmit HIV at very low rates, transmission can be attributed to a combination of these factors (28.9). Service needs are greatest for MSM; their number with unsuppressed viral load engaging in unprotected discordant sex was 8 times the number of male heterosexuals and more than twice the number of female heterosexuals with high-risk transmission potential. While all persons with HIV need optimal care, treatment as prevention is most relevant when risk behavior is present among persons with unsuppressed HIV viral load.

Temporal trends in sexual behavior among men who have sex with men in the United States, 2002 to 2006-2010

Little is known about national trends in sexual behavior among MSM in the US. Data from the 2002 and 2006-2010 National Survey of Family Growth were used to compare sexual behaviors of sexually active MSM. Mean number of recent male partners significantly decreased from 2.9 in 2002 to 2.1 in 2006-2010 (P = 0.027), particularly among young MSM. Other sexual risk behaviors did not change or decrease over time. Our findings that sexual risk decreased as HIV and syphilis increased among MSM suggest that factors in addition to individual-level sexual risk should also be examined in relation to recent disease increases.

Social support network characteristics and sexual risk taking among a racially/ethnically diverse sample of young, urban men who have sex with men

Associations between social support network characteristics and sexual risk among racially/ethnically diverse young men who have sex with men (YMSM) were examined using egocentric network data from a prospective cohort study of YMSM (n = 501) recruited in New York City. Bivariate and multivariable logistic regression analyses examined associations between social support network characteristics and sexual risk taking behaviors in Black, Hispanic/Latino, and White YMSM. Bivariate analyses indicated key differences in network size, composition, communication frequency and average relationship duration by race/ethnicity. In multivariable analyses, controlling for individual level sociodemographic, psychosocial and relationship factors, having a sexual partner in one's social support network was associated with unprotected sexual behavior for both Hispanic/Latino (AOR = 3.90) and White YMSM (AOR = 4.93). Further examination of key network characteristics across racial/ethnic groups are warranted in order to better understand the extant mechanisms for provision of HIV prevention programming to racially/ethnically diverse YMSM at risk for HIV.

Why culture matters in health interventions: lessons from HIV/AIDS stigma and NCDs

Theories about health behavior are commonly used in public health and often frame problems as ascribed or related to individuals' actions or inaction. This framing suggests that poor health occurs because individuals are unable or unwilling to heed preventive messages or recommended treatment actions. The recent United Nations call for strategies to reduce the global disease burden of noncommunicable diseases like diabetes requires a reassessment of individual-based approaches to behavior change. We argue that public health and health behavior intervention should focus more on culture than behavior to achieve meaningful and sustainable change resulting in positive health outcomes. To change negative health behaviors, one must first identify and promote positive health behaviors within the cultural logic of its contexts. To illustrate these points, we discuss stigma associated with obesity and human immunodeficiency virus and acquired immune deficiency syndrome. We conclude that focusing on positive behaviors and sustaining cultural and personal transformations requires a culturally grounded approach to public health interventions, such as that provided by the PEN-3 model.

Sexual health screening among racially/ethnically diverse young gay, bisexual, and other men who have sex with men

PURPOSE

Screening for sexually transmitted infections (STIs) is a crucial element of improving health and reducing disparities, and young men who have sex with men (YMSM) face high rates of both STIs and human immunodeficiency virus. We examined sexual health screening among a diverse sample of adolescent YMSM living in New York City.

METHODS

Between 2009 and 2011, cross-sectional data were collected from 590 YMSM in New York City. Separate multivariable logistic regression models were used to assess the relationship between sociodemographic, psychosocial, and health and healthcare related factors and two main outcomes: having sought a recent sexual health screening (past 6 months) and having a rectal sexual health screening (lifetime).

RESULTS

Overall, 46% reported a sexual health screening in the prior 6 months, but only 16% reported ever having a rectal screening for STIs. Rates were higher among ethnic minority YMSM and men who accessed care at clinics. Multivariable results indicated that gay community affiliation, recent unprotected anal sex, and number of lifetime male partners were also associated with seeking a recent screening.

CONCLUSIONS

Though half of the sample reported recent general screening, rates of lifetime rectal screening are low. Efforts to increase screening may focus on improving provider knowledge and guideline adherence, and educating and encouraging YMSM to access sexual health check-ups.

Prevalence and predictors of conscious risk behavior among San Franciscan men who have sex with men

We estimated the prevalence of conscious risk, specifically defined as unprotected anal intercourse with an HIV-serodiscordant partner, and identified individual-level and partnership-level predictors of this behavior. Conscious risk was estimated to be practiced by 4.8% of HIV-negative MSM and 15.7% of HIV-positive MSM over a six-month period (p < 0.01). Among HIV-negative MSM, episodes of conscious risk were estimated to be more frequent among individuals between the ages of 18 and 24 (compared to those 55 years of age or older), among African Americans and Whites (compared to Latinos and Asians), individuals earning less than 10,000 dollars per year (compared to those earning 50,000 and 70,000 dollars per year), and among users of methamphetamine, downers, pain killers, and amyl nitrate (poppers). Among HIV-positive MSM, episodes of conscious risk were more frequent among Whites and Asians (compared to those of "other" races, i.e., those of mixed race, or those who did not exclusively self-report as White, Black, Latino, or Asian), those with full-time employment (as opposed to those with part-time employment), those earning between 30,000 and 50,000 dollars per year or 70,000 dollars per year or greater (compared to those earning under 10,000 dollars per year), and recent users of poppers. Conscious risk was more frequently reported in partnerships with large age gaps and in main partnerships (as opposed to casual or exchange partnerships). Individuals at high risk for conscious risk may be ideal candidates for pre-exposure prophylaxis (PrEP).

Association of discrimination-related trauma with sexual risk among HIV-positive African American men who have sex with men

OBJECTIVES

We investigated whether 1 form of traumatic stress, discrimination-related trauma (e.g., physical assault because of race), was associated with unprotected anal intercourse, especially when compared with non-discrimination-related trauma, among African American men who have sex with men.

METHODS

A convenience sample of 131 HIV-positive African American men who have sex with men receiving antiretroviral treatment completed audio computer-assisted self-interviews that covered unprotected anal intercourse, interpersonal trauma, and whether trauma was because of discrimination on the basis of race/ethnicity, HIV serostatus, or sexual orientation.

RESULTS

Sixty percent reported at least 1 interpersonal trauma; they attributed at least 1 trauma to being gay (47%), African American (17%), or HIV positive (9%). In a multivariate regression, experiencing discrimination-related trauma was significantly associated with unprotected anal intercourse (adjusted odds ratio [AOR] = 2.4; 95% confidence interval [CI] = 1.0, 5.7; P = .04), whereas experiencing non-discrimination-related trauma was not (AOR = 1.3; 95% CI = 0.6, 3.1; P = .53).

CONCLUSIONS

HIV-positive African American men who have sex with men experience high levels of discrimination-related trauma, a stressor associated with greater risk taking. HIV prevention interventions should consider the potential damaging effects of discrimination in the context of trauma.

Individual, psychosocial, and social correlates of unprotected anal intercourse in a new generation of young men who have sex with men in New York City

OBJECTIVES

We examined associations of individual, psychosocial, and social factors with unprotected anal intercourse (UAI) among young men who have sex with men in New York City.

METHODS

Using baseline assessment data from 592 young men who have sex with men participating in an ongoing prospective cohort study, we conducted multivariable logistic regression analyses to examine the associations between covariates and likelihood of recently engaging in UAI with same-sex partners.

RESULTS

Nineteen percent reported recent UAI with a same-sex partner. In multivariable models, being in a current relationship with another man (adjusted odds ratio [AOR] = 4.87), an arrest history (AOR = 2.01), greater residential instability (AOR = 1.75), and unstable housing or homelessness (AOR = 3.10) was associated with recent UAI. Although high levels of gay community affinity and low internalized homophobia were associated with engaging in UAI in bivariate analyses, these associations did not persist in multivariable analyses.

CONCLUSIONS

Associations of psychosocial and socially produced conditions with UAI among a new generation of young men who have sex with men warrant that HIV prevention programs and policies address structural factors that predispose sexual risk behaviors.

Convergence of HIV prevalence and inter-racial sexual mixing among men who have sex with men, San Francisco, 2004-2011

Disparity in HIV prevalence by race/ethnicity has been noted among men who have sex with men for almost 20 years. Research suggests that rather than individual risk behaviors, sexual networks play an important role in HIV prevalence disparity. This analysis uses data from the National HIV Behavioral Surveillance System collected at three time points using time-location sampling in 2004, 2008, 2011. We use Newman's coefficient to assess racial mixing among 1,207 observations. We found significant differences in HIV status across race groups in 2004 and 2008; yet in 2011, there were no significant differences of HIV status by race. Racial mixing across all races increased from 2004 to 2011; in other words, individuals were increasingly more likely to sexually partner outside their own race/ethnicities. Increased racial mixing may explain this convergence, although full social network studies are necessary in order to fully explain these findings.

Homophobia is associated with sexual behavior that increases risk of acquiring and transmitting HIV infection among black men who have sex with men

We investigated whether the experience of homophobic events increases the odds of engaging in unprotected anal intercourse (UAI) among black men who have sex with men (MSM) and whether social integration level buffered the association. Participants (N = 1,154) reported homophobic events experienced in the past 12 months. Social integration measures included social support, closeness with family members and friends, attachment to the black gay community, openness about sexuality within religious communities, and MSM social network size. Logistic regression analyses indicated that experiencing homophobia was associated with (1) UAI among men not previously diagnosed with HIV and (2) sexual HIV transmission risk behavior among men who knew they were HIV-infected. None of the social integration measures buffered these associations. Homophobia may promote acquisition and transmission of HIV infection among black MSM. Interventions are needed to reduce homophobia experienced by black MSM.

Preexposure prophylaxis for adolescents and young adults at risk for HIV infection: is an ounce of prevention worth a pound of cure?

An alarming proportion of incident human immunodeficiency virus (HIV) infections worldwide occur in youth. In the United States, 69% of all new infections among youth occurred in young men who have sex with men (YMSM). Recent studies show the promise of preexposure prophylaxis (PrEP) for preventing HIV infection, but research efforts suffer from disproportionately low representation of the youth who are most at risk. Youth-focused research is critical and should include behavioral, community, and biomedical interventions to create a comprehensive HIV prevention package. The many ethical, legal, and regulatory considerations in conducting HIV research among, and in providing care services to, youth must be addressed so that those at high risk and most likely to benefit can have unfettered access to safe and effective health-promoting interventions. YMSM and minority youth are at substantial HIV risk and urgently need effective HIV prevention tools for which the short and long-term benefits and risks have been carefully considered.

Social geographies of African American men who have sex with men (MSM): a qualitative exploration of the social, spatial and temporal context of HIV risk in Baltimore, Maryland

This qualitative study utilized a time-geography framework to explore the daily routines and daily paths of African American men who have sex with men (AA MSM) and how these shape HIV risk. Twenty AA MSM aged 18 years and older completed an in-depth interview. Findings revealed (1) paths and routines were differentiated by indicators of socio-economic status, namely employment and addiction, and (2) risk was situated within social and spatial processes that included dimensions of MSM disclosure and substance use. This study highlights the critical need for future research and interventions that incorporate the social and spatial dimensions of behavior to advance our ability to explain racial disparities in HIV and develop effective public health responses.

Sociodemographic characteristics explain differences in unprotected sexual behavior among young HIV-negative gay, bisexual, and other YMSM in New York City

Young gay, bisexual, and other men who have sex with men (YMSM) under age 30 in New York City are at high risk for acquiring HIV. Using the theoretical framing of fundamental causes, this analysis examined the extent to which sociodemographic factors (race/ethnicity, perceived familial socioeconomic status [SES], U.S.-born status, and sexual orientation) explain the likelihood that HIV-negative YMSM ages 18 and 19 engage in unprotected sexual behavior, which may place them at risk for serconversion. Data were drawn from the baseline (Wave 1) assessment of a cohort study (N=592) collected between July 2009 and May 2011. The sample consisted predominantly of racial/ethnic minority YMSM (70.8%). A high level of association was demonstrated for each of the demographic factors with unprotected sexual behaviors. Multinomial logistic regression analyses were undertaken to examine associations between demographic covariates with the likelihood of engaging in unprotected sexual behaviors with male partners (any unprotected anal intercourse, as well as unprotected receptive anal, insertive anal, and receptive oral intercourse) irrespective of partner serostatus, in the month prior to assessment. U.S-born status and perceived socioeconomic status consistently were significant in differentiating risk behaviors. Being born outside the U.S. and perceiving a lower SES was associated with greater levels of risk. These findings suggest that efforts to address the disproportionate burden of HIV disease among YMSM in the United States must not focus solely on issues of race/ethnicity, but must be tailored and targeted to low SES and foreign-born young gay and bisexual men. It is posited that these demographic factors may lead to disproportionate levels of psychosocial burdens, which engender risk.

Racial differences in same-race partnering and the effects of sexual partnership characteristics on HIV Risk in MSM: a prospective sexual diary study

BACKGROUND

Men who have sex with men (MSM) account for more than half of new HIV infections each year, and young black MSM experience the highest incidence rates. Black MSM have not been found to engage in more HIV risk behaviors, and it has been proposed that sexual network factors (racially homophilous networks) and partnership characteristics (influence of older partners and familiarity with partners) may help account for this disparity.

METHODS

One hundred forty-three ethnically diverse MSM were enrolled in an online prospective diary study of sexual behavior. Participants completed weekly diaries of sexual encounters and associated situational factors for 12 weeks. All analyses were conducted with Hierarchical Linear Modeling software.

RESULTS

Black MSM reported significantly less unprotected sex than other groups and were the most racially homophilous group in terms of sexual partnerships. Having older sexual partners and familiarity with partners were both associated with increased odds of sexual risk in black MSM only. A 3-way interaction between participant age, participant race, and sexual partner age revealed a strong association between having older partners and odds of sexual risk for young black MSM, and a strong association between having younger partners and sexual risk for older non-black MSM.

CONCLUSIONS

Findings expand upon previous theory and cross-sectional research. Results indicate that some of the driving forces behind the disproportionate HIV incidence in black MSM may be the greater likelihood of racially homophilous sexual networks combined with the stronger influence of sexual partner age and familiarity with partners on condom use.

Black gay men as sexual subjects: race, racialisation and the social relations of sex among Black gay men in Toronto

In this study of Black gay and bisexual men in Toronto, sexually active survey participants reported on their sexual behaviours with male partners of different ethnoracial backgrounds, and interview participants reflected on how their sexual relationships emerged in the context of race and interracial desire. Most survey participants reported sexual relationships with other Black men. Participants were more likely to be insertive with White and other ethnoracial men than with Black men. A significant number of participants who were receptive or versatile with Black partners switched to the insertive role when their sexual partners were not Black. Interview participants ascribed a sense of fulfilment to their sexual relationships with other Black men, but avoided relationships with White men or interpreted such relationships as either purely sexual and/or inflected by their racialised objectification. Others avoided sexual relationships with other Black men or preferred relationships with White men, sometimes in opposition to experiences of oppressive masculinity from some Black partners but mindful of the possibility of racialised encounters with their White partners. Study participants emerge as informed sexual subjects, self-conscious about their sexual relationships and variously inclined to negotiate or resist racialisation and oppression in the private and public spheres.

Family network proportion and HIV risk among black men who have sex with men

OBJECTIVES

Black men who have sex with men (BMSM) have the highest rates of HIV in the United States. Despite increased attention to social and sexual networks as a framework for biomedical intervention, the role of family in these networks and their relationship to HIV prevention have received limited attention.

METHODS

A network sample (N = 380) of BMSM (n = 204) and their family members (n = 176) was generated through respondent-driven sampling of BMSM and elicitation of their personal networks. The proportion of personal network members who were family was calculated, and the weighted logistic regression was used to assess the relationship between this proportion and unprotected anal intercourse, sex-drug use (SDU), and group sex (GS), as well as intravention efforts to discourage these risk behaviors among their MSM social networks.

RESULTS

45.3% of respondents listed at least 1 family member in their close personal network. Greater family network proportion (having 2 or more family members in the close network) was associated with less SDU [adjusted odds ratio (AOR) 0.38, 95% CI: 0.17 to 0.87] and participation in GS (AOR 0.25, 95% CI: 0.10 to 0.67). For intravention, BMSM with greater family proportion were more likely to discourage GS (AOR 3.83, 95% CI: 1.56 to 9.43) and SDU (AOR 2.18, 95% CI: 1.35 to 3.54) among their MSM friend network. Moreover, increased male family network proportion was associated with lower HIV risk and greater intravention than increased female network proportion.

CONCLUSIONS

Nearly half of BMSM have a close family member with whom they share personal information. Combination prevention interventions might be made more potent if this often overlooked component of personal networks was incorporated.

Health care and HIV testing experiences among Black men in the South: implications for "Seek, Test, Treat, and Retain" HIV prevention strategies

Few studies have explored how overall general health care and HIV/STI testing experiences may influence receipt of "Seek, Test, Treat, and Retain" (STTR) HIV prevention approaches among Black men in the southern United States. Using in-depth qualitative interviews with 78 HIV-negative/unknown Black men in Georgia, we explored factors influencing their general health care and HIV/STI testing experiences. The Andersen behavioral model of health care utilization (Andersen model) offers a useful framework through which to examine the general health care experiences and HIV testing practices of Black men. It has four primary domains: Environment, Population characteristics, Health behavior, and Outcomes. Within the Andersen model framework, participants described four main themes that influenced HIV testing: access to insurance, patient-provider communication, quality of services, and personal belief systems. If STTR is to be successful among Black men, improving access and quality of general health care, integrating HIV testing into general health care, promoting health empowerment, and consumer satisfaction should be addressed.
