High HIV incidence and prevalence and associated factors among young MSM, 2008

HIV Prevention in Gay Family and House Networks: Fostering Self-Determination and Sexual Safety

Many gay, bisexual, and transgender (GBT) people of color (POC) join house and/or constructed family communities, which serve as support networks composed mostly of other non-biologically related GBT/POC. These networks can decrease or increase the risk of exposure to HIV via multiple mechanisms (e.g., providing informal sexual safety education versus stigmatizing family members with HIV, encouraging sexual safety practices versus unsafe escorting, teaching self-care versus substance use) but act to support family members in the face of social and economic hardship. Researchers interviewed ten members of these social networks in the Boston metro area of the US and produced a saturated grounded theory analysis to explore the role of gay family/house networks in HIV risk management. While network members utilized HIV prevention resources, interviewees described how their efficacy was related to the intentions of leadership and strength of kinship boundaries within their community, economic opportunities, and communication skills. Clinical and research implications are discussed.

Parental Monitoring Among Young Men Who Have Sex With Men: Associations With Sexual Activity and HIV-Related Sexual Risk Behaviors

PURPOSE

Young men who have sex with men (YMSM) are at disproportionate risk for HIV infection. Parental monitoring is protective against adolescent sexual risk behavior among heterosexual adolescents, yet it is unclear whether these findings generalize to YMSM. YMSM experience unique family dynamics during adolescence, including coming out to parents and parental rejection of sexual orientation. The present study examined how theoretically derived parental monitoring constructs were associated with sexual activity and sexual risk behaviors among YMSM.

METHODS

YMSM aged 14-18 years completed a cross-sectional online survey (n = 646). Factor analysis was completed to determine factor structure of monitoring measure. Sexual behaviors were predicted from monitoring constructs and covariates within regression models.

RESULTS

Parental knowledge and adolescent disclosure, parental solicitation, parental control, and adolescent secret-keeping emerged as four distinct monitoring constructs among YMSM. Higher knowledge and disclosure (b = -.32, p = .022), higher control (b = -.28, p = .006), lower solicitation (b = .31, p = .008), and lower secret-keeping (b = .25, p = .015) were associated with lower odds of sexual activity with males in the past 6 months. Higher knowledge and disclosure (b = -.12, p = .016), higher control (b = -.08, p = .039), and lower secret-keeping (b = .11, p = .005) were associated with having fewer recent sexual partners. Monitoring constructs were unassociated with condomless anal intercourse instances among sexually active YMSM.

CONCLUSIONS

YMSM disclosure is closely tied with parental knowledge, and parents should foster relationships and home environments where YMSM are comfortable disclosing information freely. Effective parental monitoring could limit YMSM's opportunities for sexual activity, but monitoring is not sufficient to protect against HIV-related sexual risk behaviors among sexually active YMSM.

Female and younger subjects have lower adherence in PrEP trials: a meta-analysis with implications for the uptake of PrEP service to prevent HIV

OBJECTIVE

To estimate the medicine-taking compliance (MTC) level, explore its facilitators and barriers, and quantify the association between MTC level and pre-exposure prophylaxis (PrEP) protective efficacy in individuals at risk of acquiring HIV being administered oral PrEP.

DESIGN

Meta-analysis.

DATA SOURCES

We searched PubMed, Cochrane and Embase databases for published randomized controlled trials (RCTs) pertaining to MTC of oral PrEP for HIV prevention up to 16 January 2017.

REVIEW METHODS

The pooled proportion of MTC and risk ratio (RR) of HIV incidences between intervention group and control group were estimated.

RESULTS

We identified 10 eligible studies with 24 193 participants. The overall pooled MTC for oral HIV PrEP was 59.9% (95% CI 43.1% to 74.6%). Subgroup analyses revealed that the MTC level of participants aged <30 years was lower than those equal or older than 30 years (34.9% vs 69.6%, p<0.001); those studies that enrolled only women as participants had lower MTC than those only recruiting either only men or both men and women (31.3% vs 71.7% and 31.3% vs 71.0%, all p<0.01). Additionally, the HIV infection risk increased as the MTC level declines, with the incidence RRs being 0.28 (95% CI 0.19 to 0.41), 0.42 (95% CI 0.29 to 0.62) and 0.75 (95% CI 0.45 to 1.25) in the good (≥80%), moderate (60%~80%) and poor (<60%) MTC subgroups, respectively (linear trend test p<0.01).

CONCLUSION

According to the pooled proportion, the MTC of oral HIV PrEP is almost moderate, and its proportion in women and younger participants was relatively low. The protective efficacy of oral PrEP for HIV prevention increased with MTC level. These findings indicated that it is necessary to identify measures to enhance MTC of oral PrEP in future clinical usage, especially in women and younger participants with high HIV infection risk.

Cognitive and Behavioral Resilience Among Young Gay and Bisexual Men Living with HIV

PURPOSE

HIV/AIDS disproportionately affects young gay, bisexual, and other men who have sex with men (Y-GBMSM). Resilience remains understudied among Y-GBMSM living with HIV, but represents a potentially important framework for improving HIV-related outcomes in this population. We sought to explore cognitive and behavioral dimensions of resilience and their correlates among Y-GBMSM to gain insights to inform future interventions.

METHODS

Our study sample consisted of 200 Y-GBMSM living with HIV enrolled in a multisite study of the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Participants completed a one-time, self-administered structured questionnaire, including validated scales capturing a range of cognitive, behavioral, demographic, and psychosocial data. Utilizing these data, we examined cognitive and behavioral dimensions of resilience and their potential psychosocial correlates using linear regression modeling.

RESULTS

Multiple regression analyses demonstrated that education, stigma, social support, ethnic identity, internalized homonegativity, and behavioral resilience were statistically significant predictors of cognitive resilience (P < 0.001, R² = 0.678). Social support satisfaction and cognitive resilience were significant predictors of behavioral resilience (P < 0.001, R² = 0.141).

CONCLUSIONS

Our findings point to potential strategies for incorporating resilience-promoting features into future interventions to support Y-GBMSM living with HIV. Specifically, strengths-based interventions in this population should seek to enhance social support, promote positive identity development, and encourage education. Future research can also seek to utilize and refine our measures of resilience among youth.

CDC-funded HIV testing, HIV positivity, and linkage to HIV medical care in non-health care settings among young men who have sex with men (YMSM) in the United States

In the United States, HIV infection disproportionately affects young gay, bisexual, and other men who have sex with men, aged 13-24 years (collectively referred to as YMSM), specifically black YMSM. Knowledge of HIV status is the first step for timely and essential prevention and treatment services. Because YMSM are disproportionately affected by HIV, the number of CDC-funded HIV testing events, overall and newly diagnosed HIV positivity, and linkage to HIV medical care among YMSM in non-health care settings were examined from 61 health department jurisdictions. Differences by age and race/ethnicity were analyzed. Additionally, trends in number of HIV testing events and newly diagnosed HIV positivity were examined from 2011 to 2015. In 2015, 42,184 testing events were conducted among YMSM in non-health care settings; this represents only 6% of tests in non-health care settings. Overall and newly diagnosed HIV positivity was 2.8% and 2.1%, respectively, with black/African-American YMSM being disproportionately affected (5.6% for overall; 4% for newly diagnosed); 71% of YMSM were linked within 90 days. The newly diagnosed HIV positivity among YMSM decreased from 2.8% in 2011 to 2.4% in 2015, and the number of newly diagnosed YMSM also decreased. Further targeted testing efforts among YMSM are needed to identify undiagnosed YMSM, specifically black YMSM.

Social-ecological factors associated with HIV infection among men who have sex with men in Jamaica

In Jamaica, where homosexuality is criminalized, scant research has examined associations between sexual stigma and HIV infection. The study objective was to examine correlates of HIV infection among men who have sex with men (MSM) in Jamaica. We conducted a cross-sectional tablet-based survey with MSM in Jamaica using chain referral sampling. We assessed socio-demographic, individual, social, and structural factors associated with HIV infection. A logit-link model, fit using backwards-stepwise regression, was used to estimate a final multivariable model. Among 498 participants (median age: 24, interquartile range: 22-28), 67 (13.5%) were HIV-positive. In the multivariable model, HIV infection was associated with increased odds of socio-demographic (older age, odds ratio [OR]: 1.05, 95% confidence interval [CI]: 1.00-1.10]; residing in Kingston versus Ocho Rios [OR: 6.99, 95% CI 2.54-19.26]), individual (poor/fair versus excellent/good self-rated health [OR: 4.55, 95% CI: 1.81-11.42], sexually transmitted infection [STI] history [OR: 3.67, 95% CI: 1.61-8.38]), and structural (enacted sexual stigma [OR: 1.08, 95% CI: 1.01-1.15], having a health care provider [OR: 2.23, 95% CI: 1.06-4.66]) factors. This is among the first studies to demonstrate associations between sexual stigma and HIV infection in Jamaica. Findings underscore the need to integrate STI testing in the HIV care continuum and to address stigma and regional differences among MSM in Jamaica.

Effects of Parental Monitoring and Knowledge on Substance Use and HIV Risk Behaviors Among Young Men Who have Sex with Men: Results from Three Studies

Young men who have sex with men (YMSM) are disproportionately impacted by HIV/AIDS and have elevated rates of substance use. Parenting practices, such as knowledge of child whereabouts and monitoring of behavioral rules, protect against these outcomes among heterosexual youth. This article examined the relationship between these parenting practices and substance use and HIV risk behaviors among YMSM. Data are reported from three similar studies of YMSM: ChiGuys (ages 14-18), Crew 450 (ages 16-22), and RADAR (ages 16-29). The ChiGuys and RADAR studies report cross-sectional analyses, whereas Crew 450 reports latent growth curve analyses. In ChiGuys and Crew 450, participants reported significantly higher scores for parental knowledge of general activities than parental knowledge of gay-specific activities. Parental knowledge of general activities was significantly associated with less binge drinking in both samples and with condomless sex in the ChiGuys sample. Parental monitoring was significantly associated with less marijuana use and condomless sex in younger RADAR participants (16-18 years) and with less drug use in older participants (>18 years). Findings support the need for further research on the influences of parents on YMSM health risk behaviors and the value of exploring family- and parent-interventions to address YMSM health.

A longitudinal examination of factors associated with social support satisfaction among HIV-positive young Black men who have sex with men

This study examined the long-term predictors of social support satisfaction among HIV-positive young Black men who have sex with men (YBMSM). Data were collected across three waves between October 2012 and November 2014 as part of the baseline assessment from Project nGage, a preliminary efficacy randomized control study examining the role of social support in improving HIV care among YBMSM. The sample included 92 YBMSM aged 18-29. Major results controlling for age, education and intervention effects indicated that psychological health, social network size, and education at baseline predicted differences in social support satisfaction at Wave 3, with no significant effects based on length of HIV diagnosis. Therefore, interventions that are intended to promote the quality of life for YBMSM and their engagement and retention in HIV care must focus on their psychological health concerns and network size.

Multiplex Competition, Collaboration, and Funding Networks Among Health and Social Organizations: Toward Organization-based HIV Interventions for Young Men Who Have Sex With Men

BACKGROUND

Young men who have sex with men (YMSM) have the highest rates of human immunodeficiency virus (HIV) infection in the United States. Decades into the HIV epidemic, the relationships that YMSM-serving health and social organizations have with one another has not been studied in depth.

OBJECTIVES

The aim of this study was to examine the competition, collaboration, and funding source structures of multiplex organization networks and the mechanisms that promote fruitful relationships among these organizations.

RESEARCH DESIGN

The study data collection method was a survey of health and social organizations from 2013-2014 in 2 cities, Chicago, IL and Houston, TX.

SUBJECTS

Study participants were representatives from 138 health and social organizations.

MEASURES

Responses to survey questions were used to reconstruct competition, collaboration, and combined competition-collaboration networks.

RESULTS

While taking into consideration the collaborative relationships among organizations, we provide statistical evidence that organizations of similar type, similar social media use patterns, comparable patterns of funding, and similar network contexts tended to compete with one another. This competition was less likely to be accompanied by any sort of collaboration if the organizations shared common funding sources.

CONCLUSIONS

Competition that excludes potential collaboration may be detrimental to mobilizing the collective efforts that serve local YMSM communities. System-level interventions may provide promising approaches to scaling-up HIV prevention and treatment efforts so as to encourage organizations to form partnerships with otherwise competing providers.

Prospective Effects of a Syndemic on HIV and STI Incidence and Risk Behaviors in a Cohort of Young Men Who Have Sex with Men

Young men who have sex with men continue to be highly affected by HIV. To improve understanding of the role that multiple co-occurring health issues (i.e., syndemics) play in HIV acquisition, sophisticated modeling methods are needed. The purpose of this study was to use structural equation modeling to understand the structure of the syndemic and to test its longitudinal association with condomless anal sex. Data are from a longitudinal study of 450 YMSM. A primary syndemic component comprised of substance use, violence, and internalizing mental health factors significantly predicted the number of condomless anal sex partners in the full sample. Analyses exploring associations by race/ethnicity found a significant association among White YMSM, but not among Black or Latino YMSM. Higher-order factor modeling suggests these psychosocial factors form a syndemic in all racial/ethnic groups, but the syndemic, as conceptualized here, may be less relevant to racial/ethnic minority YMSM.

Generational analysis of trends in unprotected sex in France among men who have sex with men: The major role of context-driven evolving patterns

OBJECTIVE

Using a generational approach, this study analyses how unprotected anal intercourse has evolved since 1991 in France across different generations of men who have sex with men (MSM) whose sexual lives began at different periods in the history of the HIV epidemic.

DESIGN

Data were collected from 18-59 year-old respondents to the French Gay Press surveys Enquêtes Presse Gay, conducted repeatedly between 1991 and 2011 (N = 32,196) using self-administered questionnaires distributed in gay magazines and over the internet.

METHODS

Trends in unprotected anal intercourse (i.e. condomless anal sex) with casual partners of unknown or different HIV serostatus (hereafter "UAId" in this manuscript) were studied. Responses were analysed according to year and then reorganised for age-cohort analyses by generation, based on the year respondents turned 18.

RESULTS

UAId rates fell from 1991 to 1997, and then rose from 13.4% in 1997 to 25.5% in 2011 among seronegative respondents, and from 24.8% to 63.3%, respectively, among seropositive respondents. Both in seropositive and seronegative respondents, UAId increased over time for all generations, indicative of a strong period effect.

CONCLUSION

Analyses of data from several generations of MSM who started their sexual lives at different time points in the HIV epidemic, revealed very similar trends in UAId between generations, among both seropositive and seronegative respondents. This strong period effect suggests that sexual behaviours in MSM are influenced more by contextual than generational factors. The fact that prevention practices are simultaneously observed in different generations and that there are most likely underlying prevention norms among MSM, suggests that PrEP could become widely accepted by all generations of MSM exposed to the risk of HIV.

HIV Testing Among Internet-Using MSM in the United States: Systematic Review

Regular HIV testing enables early identification and treatment of HIV among at-risk men who have sex with men (MSM). Characterizing HIV testing needs for Internet-using MSM informs development of Internet-facilitated testing interventions. In this systematic review we analyze HIV testing patterns among Internet-using MSM in the United States who report, through participation in an online study or survey, their HIV status as negative or unknown and identify demographic or behavioral risk factors associated with testing. We systematically searched multiple electronic databases for relevant English-language articles published between January 1, 2005 and December 16, 2014. Using meta-analysis, we summarized the proportion of Internet-using MSM who had ever tested for HIV and the proportion who tested in the 12 months preceding participation in the online study or survey. We also identified factors predictive of these outcomes using meta-regression and narrative synthesis. Thirty-two studies that enrolled 83,186 MSM met our inclusion criteria. Among the studies reporting data for each outcome, 85 % (95 % CI 82-87 %) of participants had ever tested, and 58 % (95 % CI 53-63 %) had tested in the year preceding enrollment in the study, among those for whom those data were reported. Age over 30 years, at least a college education, use of drugs, and self-identification as being homosexual or gay were associated with ever having tested for HIV. A large majority of Internet-using MSM indicated they had been tested for HIV at some point in the past. A smaller proportion-but still a majority-reported they had been tested within the year preceding study or survey participation. MSM who self-identify as heterosexual or bisexual, are younger, or who use drugs (including non-injection drugs) may be less likely to have ever tested for HIV. The overall findings of our systematic review are encouraging; however, a subpopulation of MSM may benefit from targeted outreach. These findings indicate unmet needs for HIV testing among Internet-using MSM and identify subpopulations that might benefit from targeted outreach, such as provision of HIV self-testing kits.

Using a social ecological framework to characterize the correlates of HIV among men who have sex with men in Lomé, Togo

In the mixed and concentrated HIV epidemics of West Africa, the relative disproportionate burden of HIV among men who have sex with men (MSM) compared to other reproductive-age men is higher than that observed in Southern and Eastern Africa. Our aim is to describe the correlates of HIV infection among MSM living in Lomé, Togo, using the Modified Social Ecological Model (MSEM). A total of 354 MSM ≥18 years of age were recruited using respondent driven sampling (RDS) for a cross-sectional survey in Lomé, Togo. Participants completed a structured questionnaire and were tested for HIV and syphilis. Statistical analyses included RDS-weighted proportions, bootstrapped confidence intervals (CI), and logistic regression models. Mean age of participants was 22 years; 71.5% were between 18 and 24 years. RDS-weighted HIV prevalence was 9.2% (95% CI=5.4-13.2). In RDS-adjusted (RDSa) bivariate analysis, HIV infection was associated with disclosure of sexual orientation to a family member, discriminatory remarks made by family members, forced sex, ever being blackmailed because of being MSM, community and social stigma and discrimination, and health service stigma and discrimination. In the multivariable model, HIV infection was associated with being 25 years or older (RDSa adjusted OR (aOR)=4.3, 95% CI=1.5-12.2), and having sex with a man before age 18 (RDSa aOR=0.3, 95% CI=0.1-0.9). HIV prevalence was more than seven times higher than that estimated among adults aged 15-49 living in Togo. Using the MSEM, network, community, and policy-level factors were associated with HIV infection among MSM in Lomé, Togo. Through the use of this flexible risk framework, a structured assessment of the multiple levels of HIV risk was characterized, highlighting the need for evidence-based and human-rights affirming combination HIV prevention and treatment programs that address these various risk levels for MSM in Lomé.

High HIV incidence among young black men who have sex with men: constructing a retrospective cohort from a community health programme

OBJECTIVES

We sought to calculate HIV incidence in a retrospective cohort of young (13-29 years old) black men who have sex with men (YBMSM) accessing repeated HIV-antibody testing in a mid-size city in the USA.

METHODS

We aggregated site-specific HIV-antibody testing results from the project's inception among YBMSM who received an initial negative result and accessed at least one additional HIV-antibody test. From these data, we assessed number of seroconversions and person-years and calculated HIV incidence using a mid-P exact test to estimate 95% CIs.

RESULTS

Five seroconversions were documented over 42.3 person-years (the mean age at first onsite test: 19.7 years), resulting in an HIV incidence rate of 11.8% (95% CI 4.3% to 26.2%). The mean age at seroconversion was 20.4 (±3.0) years.

CONCLUSIONS

Even in mid-size cities with low HIV prevalence rates in the general population, HIV incidence among YBMSM may be high. Community-based HIV-antibody testing organisations serving YBMSM should be encouraged and trained to track repeated HIV testing and calculate HIV incidence rates. Increased resources should be deployed to develop and encourage regular HIV testing in community health sites serving YBMSM.

Concordance of Demographic Characteristics, Sexual Behaviors, and Relationship Attributes Among Sex Dyads of Black and White Men Who Have Sex with Men

Differences in individual behaviors have failed to explain racial disparities between Black and White men who have sex with men (MSM). However, reporting of behaviors and partner characteristics are assumed to be non-differentially reported by race. From 314 participants, this study used the two-sided data-where sexual partners provide information on each other and their relationship-of 127 dyads of Black and White MSM from Atlanta, GA, to assess the reliability of partner-reported demographic characteristics and the concordance of sexual behaviors and partnership attributes by race. We compared proportions of concordance by race using a modified kappa (K m) to assess chance-corrected agreement. The median difference in age between self- and partner-reports was 0 (0-1) years. Compared to self-reports, 97 % of the partners of Black participants and 96 % of the partners of White participants correctly classified their race. We observed poor agreement on pre-sexual discussion (K m = 0.18) and being in an ongoing relationship (K m = 0.13), with no differences by race (p = 0.11). Although not statistically significant, Black MSM dyads had lower levels of concordance for unprotected anal intercourse in the previous 12 months (68 %) compared to White dyads (90 %), with fair agreement among Black dyads (K m = 0.26). Measures of partner-reported age and race are likely accurate; however, certain self-reported sexual behaviors and partnership attributes may be unreliable and differentially reported by race. Our findings highlight the need to assess the validity of measures used to estimate HIV transmission and inform racial disparities research.

Sexual minority youth of color: A content analysis and critical review of the literature

This study analyzed the content of 125 unique reports published since 1990 that have examined the health and well-being-as well as the interpersonal and contextual experiences-of sexual minority youth of color (SMYoC). One-half of reports sampled only young men, 73% were noncomparative samples of sexual minority youth, and 68% of samples included multiple racial-ethnic groups (i.e., 32% of samples were mono-racial/ethnic). Most reports focused on health-related outcomes (i.e., sexual and mental health, substance use), while substantially fewer attended to normative developmental processes (i.e., identity development) or contextual and interpersonal relationships (i.e., family, school, community, or violence). Few reports intentionally examined how intersecting oppressions and privileges related to sexual orientation and race-ethnicity contributed to outcomes of interest. Findings suggest that research with SMYoC has been framed by a lingering deficit perspective, rather than emphasizing normative developmental processes or cultural strengths. The findings highlight areas for future research focused on minority stress, coping, and resilience of SMYoC.

HIV Infection Rates and Risk Behavior among Young Men undergoing community-based Testing in San Diego

Approximately 80% of new HIV infections in the United States occur in men. Four out of five men diagnosed with HIV infection are men who have sex with men (MSM), with an increasing proportion of young MSM (i.e. ≤24 years of age). We performed a retrospective analysis 11,873 cisgender men participating in a community based HIV screening program in San Diego between 2008 and 2014 to characterize the HIV prevalence and sexual risk behaviors among young men. In young heterosexual men HIV prevalence was lower compared to heterosexual men between 25 and 49 years of age (0.3% vs. 1.4%, p = 0.043). Among young MSM, HIV prevalence was 5.5%, per test positivity rate 3.6%, and HIV incidence 3.4 per 100 person years (95% CI 2.2–5.4). Per test positivity rate (p = 0.008) and incidence (p < 0.001) were significantly higher among young MSM than among MSM above 24-years of age. Young MSM diagnosed with HIV infection reported significantly more serodiscordant condomless anal intercourse, bacterial sexually transmitted infections, and higher rates of methamphetamine and gamma hydroxybutyrate use when compared to young MSM who tested negative. In conclusion, young MSM are particularly vulnerable to HIV infection and may represent ideal candidates for targeted prevention interventions that increase testing uptake and/or decrease the risk of acquiring HIV infection.

Risk Factors Associated With HIV Among Men Who Have Sex With Men (MSM) in Ecuador

The Joint United Nations Program on HIV/AIDS estimates that between 0.3% and 0.7% of adults aged 15 to 49 years were living with HIV in Ecuador in 2013. However, very little is known about the HIV prevalence rate among men who have sex with men (MSM) in that country. A cross-sectional survey was conducted to investigate the knowledge, attitudes, and practices regarding HIV/AIDS as well as to estimate the prevalence of HIV among MSM in one of the cities with high HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 307 adult MSM. An HIV prevalence of 10% was observed. Knowledge about HIV was high; 91% of participants could identify how HIV is transmitted. Although consistent condom use for anal sex was relatively high (89%) among participants who reported having pay-for-service clients, only 64% reported using a condom during oral sex with a client. Participants who had multiple male sexual partners (i.e., their stable male partners plus other partner[s]) had 3.7 times higher odds of testing positive for HIV compared with those who did not. They also had reduced odds of condom use. Participants who were forced to have anal receptive sex had 3 times higher odds of testing positive for HIV. Despite the finding that participants exhibited high knowledge about HIV/AIDS, a high prevalence rate of HIV was observed, which warrants targeted behavioral interventions. These data are consistent with MSM being one of the highest at-risk population groups for HIV in this region of Ecuador.

Incidence of HIV Infection and Sexually Transmitted Infections and Related Risk Factors Among Very Young Men Who Have Sex With Men

INTRODUCTION

The HIV epidemic continues to disproportionately affect men who have sex with men (MSM) in the United States, with over a third of new infections in MSM occurring in younger men. Very few studies have reported on HIV and sexually transmitted infection (STI) incidence and related risks among younger MSM, particularly among minors under 18 years of age.

METHODS

Data analyzed herein are from a longitudinal study of HIV risk among 450 very young MSM in Chicago aged 16 to 20, recruited via respondent-driven sampling and followed-up for 2 years, with annual HIV and STI testing. We report estimated cumulative HIV and STI incidence over the 24-month follow-up using Kaplan-Meier methods and evaluated associations with incident infections using Cox proportional hazards regression.

RESULTS

The final analytic sample was primarily non-white (83%); median age was 19; 25% of the sample was under age 18. Twenty-six new HIV infections were detected over 632 person-years of follow-up. HIV incidence was 4.11/100 person-years [95% confidence interval (CI): 2.80 to 6.04] and STI incidence was 6.22/100 person-years (95% CI: 4.54 to 8.51). Cumulative HIV incidence over 24 months of follow-up was 7.32% (95% CI: 5.05 to 10.57), with higher incidence among racial/ethnic minorities. In multivariate analyses, non-white race and recent sexual partner concurrency were associated with both HIV and STI infection; HIV testing history and sex with an HIV-positive partner were associated with increased risk of HIV infection.

DISCUSSION

High rates of incident HIV infection and STIs among very young MSM and the relationship between incidence and race/ethnicity, concurrency and partner characteristics indicate potential focal points of future intervention and the need for continued vigilance.

Social Media Use and HIV-Related Risk Behaviors in Young Black and Latino Gay and Bi Men and Transgender Individuals in New York City: Implications for Online Interventions

Urban young men who have sex with men (YMSM) and transgender women continue to experience high rates of new HIV infections in the USA, yet most of this population is not reached by current prevention interventions. The rate of Internet and social media use among youth is high. However, continually updated understanding of the associations between social media access and use and HIV risk behaviors is needed to reach and tailor technology-delivered interventions for those most vulnerable to HIV-racially and ethnically diverse urban YMSM and transgender persons. Thus, we conducted an in-person, venue-based cross-sectional survey among young gay, bisexual, and transgender individuals at locations primarily visited by Black and Latino gay and bisexual and transgender individuals in New York City to understand social media use and how it may relate to HIV risk behaviors to inform social media-based interventions. Among 102 primarily Black and Latino gay and bisexual men (75.5 %) and transgender women (19.6 %), over 90 % were under 30 years of age, 18.6 % reported homelessness in the past 6 months, and 10.8 % reported having HIV. All participants used social media, most accessed these platforms most often via a mobile device (67.6 %) and most logged on multiple times per day (87.3 %). Participants used social media to seek sex partners (56.7 %), exchange sex for money or clothes (19.6 %), and exchange sex for drugs (9.8 %). These results confirm prior studies demonstrating the feasibility of using social media platforms to reach at-risk, urban youth. Of particular concern is the association between recent STI and exchanging sex for money/clothes and drugs. Interventions using social media for young, urban minority MSM and transgender populations should incorporate risk reduction modules addressing exchange partners and promote frequent and regular HIV/STI testing.

Partner Preference Among Men Who Have Sex with Men: Potential Contribution to Spread of HIV Within Minority Populations

PURPOSE

Human immunodeficiency virus (HIV) disproportionately affects men who have sex with men (MSM) in the United States. Most prior research into drivers of HIV transmission has focused on individual characteristics rather than on dyadic-level behaviors such as sex partner selection. This article explores racial/ethnic preferences in sex and relationship partner selection among MSM to further contextualize the spread of HIV within minority groups.

METHODS

Participants were recruited through a mobile application (app) for men to meet other men in 2015 and completed an online survey on behaviors related to HIV risk. All analyses on the sample of 530 MSM were conducted in 2015.

RESULTS

There was significant homophily in partner selection within racial/ethnic minorities, but not for white MSM. In general, mobile app-using MSM reported a general preference for white and Hispanic men and a dispreference for black and Asian men, both for sex and relationship partners.

CONCLUSION

Racial/ethnic preferences were found to drive intentions to form partnerships within this sample. Combined with the stigma many of these racial/ethnic minorities may also feel from homophobic attitudes within their own racial/ethnic communities, these MSM may be at particular risk for social isolation. These partner preferences likely affect the structure of the sexual networks of MSM and may contribute to increased clustering within high HIV incident sexual networks.

Project YOURLIFE (What Young People Think and Feel about Relationships, Love, Sexuality, and Related Risk Behavior): Cross-sectional and Longitudinal Protocol

Introduction

Sexually transmitted infections and unplanned pregnancies affect adolescent sexual health and are serious public health concerns. They result from sexual intercourse in adolescence, which is usually associated with multiple partners, unprotected sex, and condom misuse. This behavior is related to socio-ecological factors that influence lifestyles. The YOURLIFE project aims to find out what young people think and feel about relationships, love, and sexuality, and to assess the associations between these thoughts and attitudes, adolescents’ social factors, and sexual health.

Materials and equipment

An international school-based study with a cross-sectional and optional subsequent longitudinal design. Three online questionnaires designed for adolescents aged 13/14, 15/16, and 17/18, respectively, will be used. A matching coding system will allow longitudinal follow-up when adolescents reply to follow-up surveys. Questionnaires will include questions related to sociodemographic data; information/communication technologies; leisure time; parental supervision; influences of parents/friends; information sources; messages perceived; and sexuality-related knowledge, attitudes, and opinions. The second and third questionnaires for participants aged 15/16 and 17/18 will also contain variables concerning sexual behavior. Schools will be able to use their results to tailor educational approaches targeting the needs of their students. Multivariate analyses will be performed using the larger international dataset.

Expected impact of the study on public health

The YOURLIFE project will collect comprehensive information about the socio-ecological determinants of the sexual risk-taking of schooled adolescents worldwide. Effective preventive programs could be subsequently designed and tailored to the specific determinants of adolescents from different schools and settings, and also, when analyzed globally, to public health professionals.

Sexual Risk Behavior Among Virologically Detectable Human Immunodeficiency Virus-Infected Young Men Who Have Sex With Men

IMPORTANCE

Human immunodeficiency virus (HIV) diagnoses continue to increase among young men who have sex with men (YMSM). Many YMSM living with HIV engage in sexual risk behaviors, and those who have a detectable viral load can transmit HIV to sex partners. Understanding factors that are related to sexual risk taking among virologically detectable (VL+) YMSM can inform prevention and treatment efforts.

OBJECTIVES

To describe differences between virologically suppressed (VL-) and VL+ YMSM living with HIV and to identify correlates of condomless anal intercourse (CAI) and serodiscordant CAI among VL+ YMSM.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional survey conducted from December 1, 2009, through June 30, 2012, we studied 991 HIV-infected YMSM 15 to 26 years of age at 20 adolescent HIV clinics in the United States. Data analysis was conducted December 1, 2013, through July 31, 2015.

MAIN OUTCOMES AND MEASURES

Demographic, behavioral, and psychosocial assessments obtained using audio computer-assisted self-interviews. Viral load information was obtained via blood draw or medical record abstraction.

RESULTS

Of the 991 participants, 688 (69.4%) were VL+ and 458 (46.2%) reported CAI, with 310 (31.3%) reporting serodiscordant CAI in the past 3 months. The VL+ YMSM were more likely than the VL- YMSM to report CAI (detectable, 266 [54.7%]; suppressed, 91 [44.4%]; P = .01) and serodiscordant CAI (detectable, 187 [34.9%]; suppressed, 57 [25.0%]; P < .01). Multivariable analyses indicated that among VL+ YMSM, those reporting problematic substance use were more likely to report CAI (adjusted odds ratio [AOR], 1.46; 95% CI, 1.02-2.10) and serodiscordant CAI (AOR, 1.45; 95% CI, 1.06-1.99). Black VL+ YMSM were less likely to report CAI (AOR, 0.63; 95% CI, 0.44-0.90) or serodiscordant CAI (AOR, 0.66; 95% CI, 0.46-0.94) compared with other VL+ YMSM. In addition, VL+ YMSM who disclosed their HIV status to sex partners were more likely to report CAI compared with nondisclosing YMSM (AOR, 1.35; 95% CI, 1.01-1.81). Transgender participants were less likely to report CAI than cisgender participants (AOR, 0.35; 95% CI, 0.14-0.85). Last, VL+ YMSM who reported currently being employed were less likely to report serodiscordant CAI than those who were unemployed (AOR, 0.74; 95% CI, 0.55-0.99).

CONCLUSIONS AND RELEVANCE

Targeted multilevel interventions are needed to reduce HIV transmission risk behaviors among YMSM living with HIV, particularly among those who are VL+.

Running Backwards: Consequences of Current HIV Incidence Rates for the Next Generation of Black MSM in the United States

Black men who have sex with men (MSM) in the United States are disproportionately impacted by HIV. To better understand this public health problem, we reviewed the literature to calculate an estimate of HIV incidence among Black MSM. We used this rate to model HIV prevalence over time within a simulated cohort, which we subsequently compared to prevalence from community-based samples. We searched all databases accessible through PubMed, and Conference on Retroviruses and Opportunistic Infections abstracts for HIV incidence estimates among Black MSM. Summary HIV incidence rates and 95 % confidence intervals (CIs) were calculated using random effects models. Using the average incidence rate, we modeled HIV prevalence within a simulated cohort of Black MSM (who were all HIV-negative at the start) from ages 18 through 40. Based on five incidence rates totaling 2898 Black MSM, the weighted mean incidence was 4.16 % per year (95 % CI 2.76-5.56). Using this annual incidence rate, our model predicted that 39.94 % of Black MSM within the simulated cohort would be HIV-positive by age 30, and 60.73 % by 40. Projections were similar to HIV prevalence found in community-based samples of Black MSM. High HIV prevalence will persist across the life-course among Black MSM, unless effective prevention and treatment efforts are increased to substantially reduce HIV transmission among this underserved and marginalized population.

Ten Years of Screening and Testing for Acute HIV Infection in North Carolina

OBJECTIVE

To describe demographic and behavioral characteristics of persons with acute HIV infection (AHI) over time.

METHODS

We conducted a retrospective assessment of AHI identified through the Screening and Tracing Active Transmission (STAT) program from 2003 to 2012 in North Carolina (NC). AHI was identified using pooled nucleic acid amplification for antibody negative samples and individual HIV-1 RNA for antibody indeterminate samples. The STAT program provides rapid notification and evaluation. We compared STAT-collected demographic and risk characteristics with all persons requesting tests and all non-AHI diagnoses from the NC State Laboratory of Public Health.

RESULTS

The STAT Program identified 236 AHI cases representing 3.4% (95% confidence interval: 3.0% to 3.9%) of all HIV diagnoses. AHI cases were similar to those diagnosed during established HIV. On pretest risk-assessments, AHI cases were predominately black (69.1%), male (80.1%), young (46.8% < 25 years), and men who have sex with men (MSM) (51.7%). Per postdiagnosis interviews, the median age decreased from 35 (interquartile range 25-42) to 27 (interquartile range 22-37) years, and the proportion <25 years increased from 23.8% to 45.2% (trend P = 0.04) between 2003 and 2012. AHI men were more likely to report MSM risk post-diagnosis than on pretest risk-assessments (64%-82.9%; P < 0.0001). Post-diagnosis report of MSM risk in men with AHI increased from 71.4% to 96.2%.

CONCLUSIONS

In NC, 3.4% of individuals diagnosed with HIV infection have AHI. AHI screening provides a real-time source of incidence trends, improves the diagnostic yield of HIV testing, and offers an opportunity to limit onward transmission.

A Data-Driven Simulation of HIV Spread Among Young Men Who Have Sex With Men: Role of Age and Race Mixing and STIs

OBJECTIVE

Young men who have sex with men (YMSM) in the United States have a high HIV incidence with substantial racial disparities that are poorly understood. We use a data-driven simulation model to understand the impact of network-level mechanisms and sexually transmitted infections on the spread of HIV among YMSM.

METHODS

We designed and parameterized a stochastic agent-based network simulation model using results of a longitudinal cohort study of YMSM in Chicago. Within this model, YMSM formed and dissolved partnerships over time, and partnership types were stratified by length of partnership, sex, and age of the partner. In each partnership, HIV, gonorrhea, and chlamydia could be transmitted. Counterfactual scenarios were run to examine drivers of HIV.

RESULTS

Over a 15-year simulation, the HIV epidemic among YMSM continued to rise, with Latino/white YMSM facing a steeper increase in the HIV burden compared with black YMSM. YMSM in partnerships with older MSM, in particular black YMSM with older black MSM, were at highest risk for HIV, and 1 infection prevented with an older partner would prevent 0.8 additional infections among YMSM. Additionally, racial disparities in HIV were driven by differences in the HIV prevalence of YMSM partners. Finally, of all HIV infections among YMSM, 14.6% were attributable to NG and CT infections.

CONCLUSION

Network-level mechanisms and sexually transmitted infections play a significant role in the spread of HIV and in racial disparities among YMSM. HIV prevention efforts should target YMSM across race, and interventions focusing on YMSM partnerships with older MSM might be highly effective.

Receipt of HIV prevention interventions is more common in community-based clinics than in primary care or acute care settings for Black men who have sex with men in the District of Columbia

Characterization of structural barriers that impede the receipt of HIV prevention and care services is critical to addressing the HIV epidemic among Black men who have sex with men (BMSM). This study investigated the utilization of HIV prevention and general care services among a non-clinic-based sample of BMSM who reported at least one structural barrier to engagement in care. Proportions of participants who had received HIV prevention services and general care services in different settings were compared using Fisher's exact test and correlates of service receipt were assessed using logistic regression. Among 75 BMSM, 60% had accessed a community-based clinic, 21% had accessed a primary care setting, and 36% had accessed an acute care setting in the last 6 months. Greater proportions of participants who had accessed community-based clinics received HIV prevention services during these visits (90%) compared to those who had accessed primary care (53%) and acute care (44%) settings (p = .005). Opportunities for BMSM to receive HIV prevention interventions differed by care setting. Having access to health care did not necessarily facilitate the uptake of HIV prevention interventions. Further investigation of the structurally rooted reasons why BMSM are often unable to access HIV prevention services is warranted.

Acceptability of a Mobile Smartphone Application Intervention to Improve Access to HIV Prevention and Care Services for Black Men Who Have Sex with Men in the District of Columbia

Eliminating racial HIV disparities among men who have sex with men (MSM) will require a greater uptake of HIV prevention and care interventions among Black MSM (BMSM), yet such strategies generally require meaningful engagement in a health care system that often does not meet the unique needs of BMSM. This study assessed the acceptability of, and correlates of having favorable perceptions of, a mobile smartphone application (app) intervention for BMSM that aims to remove structural barriers and improve access to culturally relevant HIV prevention and care services. An Internet-based sample of 93 BMSM completed an online survey on their perceptions of the app using 14 items measured on a 100-point visual analogue scale that were validated in exploratory factor analysis (alpha=0.95). Among the sample, perceptions of two sample app modules were generally favorable and most BMSM agreed that they would use the modules (81.2% and 87.1%). Correlates of having favorable perceptions included trusting medical advice from social networks, lacking private health insurance, and not having accessed a primary care physician in the last year. Our findings warrant the further development of this app and point to subgroups of BMSM for which it may have the greatest impact.

Preventing HIV Transmission Among Partners of HIV-Positive Male Sex Workers in Mexico City: A Modeling Study

Mexico has a concentrated HIV epidemic, with male sex workers constituting a key affected population. We estimated annual HIV cumulative incidence among male sex workers' partners, and then compared incidence under three hypothetical intervention scenarios: improving condom use; and scaling up HIV treatment as prevention, considering current viral suppression rates (CVS, 60.7 %) or full viral suppression among those treated (FVS, 100 %). Clinical and behavioral data to inform model parameterization were derived from a sample (n = 79) of male sex workers recruited from street locations and Clínica Condesa, an HIV clinic in Mexico City. We estimated annual HIV incidence among male sex workers' partners to be 8.0 % (95 % CI: 7.3-8.7). Simulation models demonstrated that increasing condom use by 10 %, and scaling up HIV treatment initiation by 50 % (from baseline values) would decrease the male sex workers-attributable annual incidence to 5.2, 4.4 % (CVS) and 3.2 % (FVS), respectively. Scaling up the number of male sex workers on ART and implementing interventions to ensure adherence is urgently required to decrease HIV incidence among male sex workers' partners in Mexico City.

Disassortative Age-Mixing Does Not Explain Differences in HIV Prevalence between Young White and Black MSM: Findings from Four Studies

OBJECTIVE

Age disassortativity is one hypothesis for HIV disparities between Black and White MSM. We examined differences in age mixing by race and the effect of partner age difference on the association between race and HIV status.

DESIGN

We used data from four studies of MSM. Participants reported information about recent sexual partners, including age, race, and sexual behavior. Two studies were online with a US sample and two focused on MSM in Atlanta.

METHODS

We computed concordance correlation coefficients (CCCs) by race across strata of partner type, participant HIV status, condom use, and number of partners. We used Wilcoxon rank-sum tests to compare Black and White MSM on partner age differences across five age groups. Finally, we used logistic regression models using race, age, and partner age difference to determine the odds ratio of HIV-positive serostatus.

RESULTS

Of 48 CCC comparisons, Black MSM were more age-disassortative than White MSM in only two. Furthermore, of 20 comparisons of median partner age, Black and White MSM differed in two age groups. One indicated larger age gaps among the Black MSM (18-19). Prevalent HIV infection was associated with race and age. Including partner age difference in the model resulted in a 2% change in the relative odds of infection among Black MSM.

CONCLUSIONS

Partner age disassortativity and partner age differences do not differ by race. Partner age difference offers little predictive value in understanding prevalent HIV infection among Black and White MSM, including diagnosis of HIV-positive status among self-reported HIV-negative individuals.

Attitudes Toward HIV Voluntary Counseling and Testing (VCT) Among African American Men Who Have Sex With Men: Concerns Underlying Reluctance to Test

Contemporary antiretroviral therapy (ART) can produce viral suppression of HIV, maintain health, and prevent onward HIV transmission from infected persons to their sexual partners, giving rise to the concept of treatment as prevention. Successful implementation of test-and-treat strategies rests on the early detection of HIV infection through voluntary counseling and testing (VCT) followed by entry and retention in care, ART initiation and adherence, and subsequent viral suppression. In the United States, African American men who have sex with men (MSM) bear a disproportionate burden of HIV and have high rates of undetected and untreated HIV infection. However, little research has examined racial minority MSM's views about HIV testing. In this study, in-depth interviews were conducted with 96 key informants knowledgeable about racial minority MSM as well as 100 African American MSM community members in Milwaukee, Cleveland, and Miami. Most men in the sample were aware of the availability of testing and knew testing locations, but many voiced great personal ambivalence about being tested, feared knowing their HIV status, expressed concern about stigma and loss of confidentiality, and held beliefs indicative of medical mistrust. Participants did not spontaneously cite benefits of being tested, risk reduction behavior changes made as a consequence of testing, nor the benefits of testing to get early medical care for HIV infection. There is a gap between the public health field's perception of testing benefits and the beliefs about testing held by racial minority MSM in this sample. To increase the desired outcomes from VCT for minority MSM, VCT promotion should address the concerns of African American MSM and underscore the benefits of early entry into medical care.

The Role of Geographic and Network Factors in Racial Disparities in HIV Among Young Men Who have Sex with Men: An Egocentric Network Study

The objective of this study was to characterize and compare individual and sexual network characteristics of Black, White, and Latino young men who have sex with men (YMSM) as potential drivers of racial disparities in HIV. Egocentric network interviews were conducted with 175 diverse YMSM who described 837 sex partners within 167 sexual-active egos. Sexual partner alter attributes were summarized by ego. Descriptives of ego demographics, sexual partner demographics, and network characteristics were calculated by race of the ego and compared. No racial differences were found in individual engagement in HIV risk behaviors or concurrent sexual partnership. Racial differences were found in partner characteristics, including female gender, non-gay sexual orientations, older age, and residence in a high HIV prevalence neighborhood. Racial differences in relationship characteristics included type of relationships (i.e., main partner) and strength of relationships. Network characteristics also showed differences, including sexual network density and assortativity by race. Most racial differences were in the direction of effects that would tend to increase HIV incidence among Black YMSM. These data suggest that racial disparities in HIV may be driven and/or maintained by a combination of racial differences in partner characteristics, assortativity by race, and increased sexual network density, rather than differences in individual's HIV risk behaviors.

Prevalence and associated factors of HIV infection among men who have sex with men in Hefei, China, 2013-2014: a cross-sectional study

The objective of this study was to investigate the prevalence and influencing factors of HIV infection among men who have sex with men (MSM) in Hefei, China. A total of 578 MSM were recruited, with a mean age of 28.13 ± 6.91; 70.7% were under 30. The awareness rate was 95.4% (560/587) in the cross-sectional study. Of all the respondents, 73 (12.44%) were seropositive for HIV and 56 (9.54%) for syphilis. Multivariate analysis showed that self-reported sexually transmitted infections (STIs) (AOR = 8.02, 95% CI: 2.58-24.98, P < 0.001), received HIV testing in the past year (AOR = 0.33, 95% CI: 0.19-0.60, P < 0.001) and syphilis (AOR = 3.40, 95% CI: 1.69- 6.85, P = 0.001) were independently associated with HIV infection. It is necessary for post-test counselling to address risk among those who engage in sexual risk behaviours. More efforts are needed to enhance HIV/STI testing and treatment services in China.

Client and provider perspectives on new HIV prevention tools for MSM in the Americas

Men who have sex with men (MSM) in the Americas require targeted, combination HIV prevention approaches. We solicited client and provider perspectives on emerging prevention interventions including HIV pre-exposure prophylaxis (PrEP) and HIV self-tests through focus groups and in-depth interviews with 130 MSM and 41 providers across four sites: New York, San Francisco, Lima, and Rio de Janeiro. Among the MSM participants, we identified three prevention typologies: non-condom users, inconsistent condom users, and consistent condom users. Northern and Southern MSM differed in the variety of harm reduction strategies utilized: where U.S. MSM relied on condom use as well as disclosure and seroadaptive behaviors for prevention, condom use without disclosure or serostatus discussions was the norm in South America. Interest in new prevention technologies was shaped by the social context. U.S. MSM preferences differed by typology, such that non-condom users were interested in taking PrEP and using home HIV tests. MSM in Brazil, regardless of typology, were interested in exploring new prevention options. MSM in Peru demonstrated moderate interest but were less comfortable with adopting new strategies. MSM and providers' opinions differed substantially with respect to new prevention options. Across sites, most providers were reticent to engage with new prevention options, though some NGO-based providers were more supportive of exploring new prevention tools. Both clients and providers will need to be engaged in developing integrated prevention strategies for MSM.

Sexual behaviours of homosexual and bisexual men in France: a generational approach

Objective

In high-income countries, the social and epidemiological contexts surrounding homosexuality and AIDS have changed profoundly in recent decades. This work sought to examine key indicators of the long-term sexual trajectories of successive generations of men who have sex with men (MSM) in France.

Methods

We performed a longitudinal analysis of the French Gay Press surveys, which were self-administered socio-behavioural questionnaires, repeated from 1985 to 2011 in the gay press, and on the internet in 2004 and 2011. An age-cohort analysis using graphical representations and multivariate logistic regressions was conducted among participants aged 18-59 (N=38 821).

Results

First sexual intercourse occurred more often with a male partner in younger generations than in older ones: 76.0% in MSM who turned 18 in 1956-1959, 75.6% in 1980-1983, 83.7% in 2008-2011, p_overall=0.0002). Every generation showed the same pattern of sexual trajectory between 1985 and 2011: globally, the frequency of masturbation increased from the 1985 survey to the early 1990s and then decreased from the late 1990s to the end of the study period. Inversely, the frequency of oral and anal sex decreased in the mid-1980s and increased from 1990 to 2011. The frequency of both oral sex and anal intercourse is currently quite high, regardless of generation (>95% and around 80%, respectively). Compared to their predecessors, recent generations of young MSM reported more frequent oral and anal sex, but fewer male partners in the previous 12 months.

Discussion

While the increased frequency of first intercourse with a man over successive generations since the 1970s may be related to reduced social pressure for heterosexuality, there is evidence that sexual norms among MSM are widespread, with practices spreading across age groups and generations. Although AIDS profoundly affected sexual practices in the 1980s, further AIDS-related events (discovery of HIV antiretroviral drugs and their use in prevention) do not appear to have accentuated ongoing trends in sexual practices.

Loss to follow-up and bias assessment among a cohort of Thai men who have sex with men in Bangkok, Thailand

Minimising loss to follow-up is essential to obtain unbiased results. This study aimed to assess factors associated with loss to follow-up and effects on biasing exposure-outcome associations in a cohort of men who have sex with men in Bangkok. We enrolled sexually-active Thai men who have sex with men, at least 18 years old, in a study with four-monthly follow-up visits. At each visit, men answered HIV risk behaviour questions using audio computer-assisted self-interview. Logistic regression was used to evaluate factors associated with loss to follow-up and bias between exposures and prevalent HIV infection were estimated using adjusted relative odds ratios. From 2006 to 2010, we enrolled 1744 men who have sex with men; as of April, 2014, 1256 (72%) had completed at least the month-36 visit; loss to follow-up was 9.6%. Factors independently associated with loss to follow-up were age (18-21 years), education (primary level or less, secondary or vocational education), living outside Bangkok and vicinity, sexual orientation (bisexual, heterosexual), previous HIV testing, HIV infection, and behaviour in the past 4 months (recreational drug use, reporting group sex). An effect of loss to follow-up on factors of prevalent HIV infection was found by sexual orientation (transgender) and unprotected anal intercourse (receptive/insertive). These findings highlight the need to strengthen post-HIV test counselling. Directed counselling for HIV care should be given to young men who have sex with men and recreational drug users.

Active recall to increase HIV and STI testing: a systematic review

BACKGROUND

Active recall can improve reattendance rates and could increase retesting rates and detection of HIV and sexually transmitted infections (STIs), but the best strategy remains uncertain.

METHODS

We conducted a systematic review and meta-analysis of active recall for HIV and/or STI testing. We searched six electronic databases using terms for HIV, STIs, tests and active recall (defined as a reminder to retest for HIV/STIs) for randomised, non-randomised and observational English-language studies published between 1983 and 2013. Outcomes included reattendance/retesting rate and STI diagnosis at follow-up.

RESULTS

Of 5634 papers identified, 17 met the inclusion criteria. Of the 14 comparative studies, all but one demonstrated higher reattendance/retesting rates in the intervention group, but the range was wide (17.5-89%). Meta-analysis of nine RCTs found reattendance/retesting rates were significantly higher in the intervention versus control groups (pooled OR 2.42 (95% CI 1.84 to 3.19)). In a subgroup analysis, home sampling increased retesting compared with clinic testing (pooled OR 2.20 (95% CI 1.65 to 2.94)). In observational studies SMS reminders increased retesting compared with standard clinic care (pooled OR 2.19 (95% CI 1.46 to 3.29)), but study estimates were highly heterogeneous (I(2)=94%, p<0.001).

CONCLUSIONS

Active recall interventions are associated with higher reattendance/retesting rates for HIV/STI. Although home sampling and SMS reminders were associated with higher reattendance/retesting rates in most studies, evidence is limited by the heterogeneity of interventions and control groups and the quality of studies. Further work is needed to explore which active recall modality is clinically cost-effective and acceptable for HIV/STI screening.

Tailored combination prevention packages and PrEP for young key populations

INTRODUCTION

Young key populations, defined in this article as men who have sex with men, transgender persons, people who sell sex and people who inject drugs, are at particularly high risk for HIV. Due to the often marginalized and sometimes criminalized status of young people who identify as members of key populations, there is a need for HIV prevention packages that account for the unique and challenging circumstances they face. Pre-exposure prophylaxis (PrEP) is likely to become an important element of combination prevention for many young key populations.

OBJECTIVE

In this paper, we discuss important challenges to HIV prevention among young key populations, identify key components of a tailored combination prevention package for this population and examine the role of PrEP in these prevention packages.

METHODS

We conducted a comprehensive review of the evidence to date on prevention strategies, challenges to prevention and combination prevention packages for young key populations. We focused specifically on the role of PrEP in these prevention packages and on young people under the age of 24, and 18 in particular.

RESULTS AND DISCUSSION

Combination prevention packages that include effective, acceptable and scalable behavioural, structural and biologic interventions are needed for all key populations to prevent new HIV infections. Interventions in these packages should meaningfully involve beneficiaries in the design and implementation of the intervention, and take into account the context in which the intervention is being delivered to thoughtfully address issues of stigma and discrimination. These interventions will likely be most effective if implemented in conjunction with strategies to facilitate an enabling environment, including increasing access to HIV testing and health services for PrEP and other prevention strategies, decriminalizing key populations' practices, increasing access to prevention and care, reducing stigma and discrimination, and fostering community empowerment. PrEP could offer a highly effective, time-limited primary prevention for young key populations if it is implemented in combination with other programs to increase access to health services and encourage the reliable use of PrEP while at risk of HIV exposure.

CONCLUSIONS

Reductions in HIV incidence will only be achieved through the implementation of combinations of interventions that include biomedical and behavioural interventions, as well as components that address social, economic and other structural factors that influence HIV prevention and transmission.

Patterns and correlates of PrEP drug detection among MSM and transgender women in the Global iPrEx Study

BACKGROUND

Adherence to pre-exposure prophylaxis (PrEP) is critical for efficacy. Antiretroviral concentrations are an objective measure of PrEP use and correlate with efficacy. Understanding patterns and correlates of drug detection can identify populations at risk for nonadherence and inform design of PrEP adherence interventions.

METHODS

Blood antiretroviral concentrations were assessed among active arm participants in iPrEx, a randomized placebo-controlled trial of emtricitabine/tenofovir in men who have sex with men and transgender women in 6 countries. We evaluated rates and correlates of drug detection among a random sample of 470 participants at week 8 and a longitudinal cohort of 303 participants through 72 weeks of follow-up.

RESULTS

Overall, 55% of participants (95% confidence interval: 49 to 60) tested at week 8 had drug detected. Drug detection was associated with older age and varied by study site. In longitudinal analysis, 31% never had drug detected, 30% always had drug detected, and 39% had an inconsistent pattern. Overall detection rates declined over time. Drug detection at some or all visits was associated with older age, indices of sexual risk, including condomless receptive anal sex, and responding "don't know" to a question about belief of PrEP efficacy (0-10 scale).

CONCLUSIONS

Distinct patterns of study product use were identified, with a significant proportion demonstrating no drug detection at any visit. Research literacy may explain greater drug detection among populations having greater research experience, such as older men who have sex with men in the United States. Greater drug detection among those reporting highest risk sexual practices is expected to increase the impact and cost-effectiveness of PrEP.

Motivational interviewing targeting risky sex in HIV-positive young Thai men who have sex with men

Motivational interviewing (MI) has been shown to reduce sexual risks among HIV-positive men who have sex with men (HMSM) in the US. We conducted a randomized trial of Healthy Choices, a 4-session MI intervention, targeting sexual risks among 110 HIV-positive youth ages 16-25 years in Thailand. Risk assessments were conducted at baseline, 1 month, and 6 months post-intervention. This report presents the analysis of 74 HMSM in the study. There were 37 HMSM in the Intervention group and 37 in the control group. The proportions of participants having anal sex and having sex with either HIV-uninfected or unknown partners in past 30 days were significantly lower in Intervention group than in Control group at 6 months post-intervention (38 vs. 65 %, p = .04; and 27 vs. 62 %, p < .01, respectively). There were no significant differences in general mental health scores and HIV stigma scores between the two groups at any study visit. Thirty-five (95 %) HMSM in the Intervention group vs. 31 (84 %) in control group attended ≥ 3 sessions. Loss to follow-up was 8 and 30 %, respectively (p = .04). Healthy Choices for young Thai HMSM was associated with sexual risk reduction. Improvements in mental health were noted in Intervention group. Healthy Choices is a promising behavioral intervention and should be further developed to serve the needs of young HMSM in resource-limited countries.

Future directions in research on sexual minority adolescent mental, behavioral, and sexual health

This article describes current knowledge on sexual, mental, and behavioral health of sexual minority (SM) youth and identifies gaps that would benefit from future research. A translational sciences framework is used to conceptualize the article, discussing findings and gaps along the spectrum from basic research on prevalence and mechanisms, to intervention development and testing, to implementation. Relative to adults, there has been much less research on adolescents and very few studies that had longitudinal follow-up beyond 1 year. Due to historical changes in the social acceptance of the SM community, new cohorts are needed to represent contemporary life experiences and associated health consequences. Important theoretical developments have occurred in conceptualizing mechanisms that drive SM health disparities and mechanistic research is underway, including studies that identify individual and structural risk/protective factors. Research opportunities exist in the utilization of sibling-comparison designs, inclusion of parents, and studying romantic relationships. Methodological innovation is needed in sampling SM populations. There has been less intervention research and approaches should consider natural resiliencies, life-course frameworks, prevention science, multiple levels of influence, and the importance of implementation. Regulatory obstacles are created when ethics boards elect to require parental permission and ethics research is needed. There has been inconsistent inclusion of SM populations in the definition of "health disparity population," which impacts funding and training opportunities. There are incredible opportunities for scholars to make substantial and foundational contributions to help address the health of SM youth, and new funding opportunities to do so.

Lack of Awareness of Human Immunodeficiency Virus (HIV) Infection: Problems and Solutions With Self-reported HIV Serostatus of Men Who Have Sex With Men

Using only self-reported information likely overestimates lack of awareness of HIV status for black MSM. Estimates that also incorporate laboratory and case surveillance measures do not show significant racial disparity in lack of awareness of HIV status.

Background

 Lack of human immunodeficiency virus (HIV) infection awareness may be a driver of racial disparities in HIV infection among men who have sex with men (MSM). Lack of awareness is typically measured by comparing HIV test result to self-reported HIV status. This measure may be subject to reporting bias and alternatives are needed.

Methods

 The InvolveMENt study examined HIV disparities between black and white MSM from Atlanta. Among HIV-positive participants who did not report knowing they were positive, we examined other measures of awareness: HIV viral load (VL) <1000 copies/mL (low VL), antiretroviral (ARV) drugs in blood, and previous HIV case surveillance report.

Results

 Using self-report only, 32% (62 of 192) of black and 16% (7 of 45) of white MSM were not aware of their HIV infection (P = .03). Using self-report and low VL, 25% (48 of 192) black and 16% (7 of 45) white MSM lacked awareness (P = .18). Using self-report and ARVs, 26% (50 of 192) black and 16% (7 of 45) white MSM lacked awareness (P = .14). Using self-report and surveillance report, 15% (28 of 192) black and 13% (6 of 45) white MSM lacked awareness (P = .83).

Conclusions

 Self-report only may overestimate true lack of awareness of HIV status for black MSM. If, as our data suggest, black MSM are not less likely to be aware of their HIV infection than are white MSM, then this factor is not a substantial driver of HIV disparity. Future HIV research that depends on accurate measurement of HIV status awareness should consider including additional laboratory and case surveillance data.

Non-occupational post-exposure prophylaxis for HIV: 10-year retrospective analysis in Seattle, Washington

Despite treatment guidelines in place since 2005, non-occupational post-exposure HIV prophylaxis (nPEP) remains an underutilized prevention strategy. We conducted a retrospective chart review of patients presenting to a publicly-funded HIV clinic in Seattle, Washington for nPEP between 2000 and 2010 (N = 360). nPEP prescriptions were provided for 324 (90%) patients; 83% of prescription decisions were appropriate according to Centers for Disease Control and Prevention guidelines, but only 31% (N = 111/360) of patients were considered "high risk." In order to use limited resources most efficiently, public health agencies should target messaging for this high-cost intervention to individuals with high-risk HIV exposures.

Correlates of sexual risk among sexual minority and heterosexual South African youths

We explored psychosocial correlates of sexual risk among heterosexual and sexual minority youths (SMYs) in Johannesburg, South Africa. Young people 16 to 18 years old (n = 822) were administered surveys assessing demographic characteristics, sexual behaviors, mental health, and parent-child communication. Adjusted multivariate regressions examining correlates of sexual risk revealed that SMYs had more sexual partners than heterosexual youths (B = 3.90; SE = 0.95; P < .001) and were more likely to engage in sex trading (OR = 3.11; CI = 1.12-8.62; P < .05). South African SMYs are at increased risk relative to their heterosexual peers.

Understanding structural barriers to accessing HIV testing and prevention services among black men who have sex with men (BMSM) in the United States

Structural-level factors have contributed to the substantial disproportionate rates of HIV among Black men who have sex with men (BMSM) in the United States. Despite insufficient HIV testing patterns, however, there is a void in research investigating the relationship between structural factors and access to HIV testing and prevention services among BMSM. Building on previous scholarly work and incorporating a dynamic social systems conceptual framework, we conducted a comprehensive review of the literature on structural barriers to HIV testing and prevention services among BMSM across four domains: healthcare, stigma and discrimination, incarceration, and poverty. We found that BMSM experience inadequate access to culturally competent services, stigma and discrimination that impede access to services, a deficiency of services in correctional institutions, and limited services in areas where BMSM live. Structural interventions that eliminate barriers to HIV testing and prevention services and provide BMSM with core skills to navigate complex systems are needed.

2014 European Guideline on HIV testing

Testing for HIV is one of the cornerstones in the fight against HIV spread. The 2014 European Guideline on HIV Testing provides advice on testing for HIV infection in individuals aged 16 years and older who present to sexually transmitted infection, genito-urinary or dermato-venereology clinics across Europe. It may also be applied in other clinical settings where HIV testing is required, particularly in primary care settings. The aim of the guideline is to provide practical guidance to clinicians and laboratories that within these settings undertake HIV testing, and to indicate standards for best practice.

Trends in HIV prevalence and HIV testing among young MSM: five United States cities, 1994-2011

We examined trends in cross-sectional HIV prevalence (a surrogate for incidence) and past 12 month testing behavior among young men who have sex with men (MSM). The Young Men's Survey and the National HIV Behavioral Surveillance System conducted interviews and HIV testing among MSM recruited by venue-based sampling during 1994-2011. Using data from five cities, we determined whether interview year was associated with HIV prevalence and recent testing for MSM ages 18-22 and 23-29 years, after adjusting for city, race/ethnicity, and education. Multivariable analysis demonstrated an overall increase in prevalence among MSM ages 23-29 years, driven by an increase in Baltimore. There was no change in HIV prevalence among MSM ages 18-22 years overall, although prevalence increased in Baltimore. HIV testing increased significantly for both age groups. Gains in HIV testing are encouraging, but increasing prevalence among young MSM in Baltimore suggests increasing incidence and the need for additional efforts for this population.
