Online social networking sites (SNS)-the Internet-based platforms that enable connection and communication between users-are increasingly salient social environments for young adults and, consequently, offer tremendous opportunity for HIV behavioral research and intervention among vulnerable populations like young men who have sex with men (YMSM). Drawing from a cohort of 525 young Black MSM (YBMSM) living in Chicago, IL, USA April 2014-May 2015, we conducted social network analysis, estimating an exponential random graph model (ERGM) to model YBMSM's group affiliations on Facebook in relation to their sex behaviors and HIV prevention traits...

PURPOSE: Young men who have sex with men (YMSM) are at an increased risk for sexually transmitted infections. Recent research has documented the importance of understanding the multidimensional nature of sexual risk behavior; however, little is known about how multidimensional patterns of sexual behavior among MSM may be associated with STIs. METHOD: This study applies latent class analysis to data from a large, HIV- sample of 18-25 year old MSM recruited from social and sexual networking websites (N = 5,965; 76% white, 11% Latino, 5% Black, 4% Asian, 4% other; 74% homosexual, 21% bisexual, 1% heterosexual, 3%, unsure/questioning 1% other) to uncover multidimensional patterns of past-year sexual behaviors, partner factors, and protective behavior and their associations with self-reported STI diagnosis...

Men who have sex with men (MSM) may be at higher risk for human papillomavirus (HPV)-associated cancers. Healthcare professionals' recommendations can affect HPV vaccination uptake. Since 2016, MSM up to 45 years have been offered HPV vaccination at genitourinary medicine (GUM) clinics in a pilot programme, and primary care was recommended as a setting for opportunistic vaccination. Vaccination prior to potential exposure to the virus (i.e., sexual debut) is likely to be most efficacious, therefore a focus on young MSM (YMSM) is important...

Behavioral diaries are frequently used for observing sexual and substance use behaviors, but participating in diary studies may cause behavior change. This study examined change in sexual and substance use behaviors among young men who have sex with men (YMSM) in a two-month diary study compared to control. An analytic sample of 324 YMSM was randomized to receive daily diaries, weekly diaries, or no diaries (control) for 2 months. Half of the diary participants were randomized to receive automated weekly feedback...

Serogroup C invasive meningococcal disease (IMD) outbreaks in men who have sex with men (MSM) have been occurring with greater frequency in urban areas across the United States. An effective vaccine for IMD is available and is recommended for MSM in outbreak settings. Particular subgroups of MSM have been disproportionately represented in outbreaks, specifically young, Black, and HIV-positive MSM. As little is known about the knowledge, awareness, and vaccination status of young MSM, we sought to describe this and explore racial/ethnic differences...

PURPOSE: Men who have sex with men (MSM) have nearly 80 times the lifetime risk of human immunodeficiency virus (HIV) relative to men who have sex with women only (MSW), and young MSM (YMSM) accounted for 95% of estimated HIV diagnoses among adolescents between 13 and 24 years in 2015. We aimed to evaluate HIV education and sexual risk behaviors among YMSM relative to young MSW (YMSW) and to evaluate the relationship between HIV education and YMSM sexual risk behaviors. METHODS: We used Youth Risk Behavior Surveillance System data from 13 states that collected information on sex of sexual contacts and on HIV education in 2011 and/or 2013...

BACKGROUND: Substantial racial disparities exist in HIV infection among young men who have sex with men (YMSM). However, evidence suggests Black YMSM do not engage in greater levels of risk behavior. Sexual networks may help explain this paradox. This study utilized egocentric exponential random graph models (ERGMs) to examine variation in concurrency (i.e., 2 or more simultaneous partners) and homophily (i.e., same race/ethnicity partners) across race/ethnicity groups in a diverse sample of YMSM...

While correlates of pre-exposure prophylaxis (PrEP) uptake have been explored among older men who have sex with men (MSM), less is known about the facilitators and barriers that encourage uptake among younger MSM (YMSM). This study explores the association between willingness to take PrEP and demographic characteristics, sexual risk, and substance use, and attitudinal factors among YMSM in California who use geosocial networking applications (GSN apps). Based on survey data from YMSM recruited through GSN apps (n = 687), PrEP willingness was positively associated with Hispanic ethnicity [adjusted odds ratio (aOR): 1...

BACKGROUND: Young men who have sex with men (YMSM) are disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition. It remains unclear if PrEP use increases rates of condomless sex (ie, risk compensation), which may increase risk of infection if PrEP adherence is not optimal. This study aimed to examine whether PrEP use and PrEP adherence were associated with change in sexual risk behaviors in a large longitudinal cohort of YMSM reporting on multiple sexual partnerships over time...

High HIV incidence has been reported in young men who have sex with men (YMSM) in North America and Western Europe, but there are limited data from Southeast Asia suggesting MSM may be the driver of the HIV epidemic in this region. We described HIV incidence and risk factors among 494 YMSM enrolled in a cohort study in Bangkok, Thailand. The HIV incidence was 7.4 per 100 person-years. In multivariable analysis, reporting use of an erectile dysfunction drug in combination with club drugs, having receptive or both insertive and receptive anal intercourse with men, having hepatitis A infection, having rectal Chlamydia trachomatis, having hepatitis B infection prior to HIV seroconversion, and reporting not always using condoms with male steady partners were significantly associated with HIV incidence in YMSM...

BACKGROUND: Associations have been observed between an aggregate viral load measure, the community viral load (CVL) and new HIV diagnoses. The CVL aggregates viral loads within chosen geographic areas, restricting inferences about HIV acquisition risk to these areas. We develop a more precise metric, the Network Viral Load (NVL) to measure the composite viral load within a risk network of an HIV negative individual. METHODS: We examined the relationship between NVL and HIV infection among Young Men who have Sex with Men (YMSM) in Chicago, United States...

INTRODUCTION: In Myanmar, men who have sex with men (MSM) experience high risk of HIV infection. However, access to HIV testing and prevention services remains a challenge among this marginalized population. The objective of this study was to estimate population prevalence and correlates of prior HIV testing among young MSM (YMSM) and informs the development of HIV testing and intervention programmes that respond to the specific needs of this population. METHODS: Five hundred and eighty-five YMSM aged 18 to 24 years were recruited using respondent-driven sampling (RDS) in a cross-sectional survey conducted in six townships of Myanmar...

Young men who have sex with men (YMSM) face a disproportionately high burden of HIV. Oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV acquisition, but adherence to PrEP among YMSM may be inadequate. Medication adherence may be assessed via biomarkers, which are expensive and invasive, or via self-report through Audio Computer Assisted Self-Interview (ACASI), which may result in over-reporting of adherence. In this paper we assess the potential of a new method of self-report, the Interactive Questionnaire System (iQS), in validly estimating true adherence rates...

Background: Much has been written about the impact of HIV among young (13-24) sexual minority men (SMM). Evidence for concern is substantial for emerging adult (18-24) SMM. Data documenting the burden and associated risk factors of HIV among adolescent SMM (<18) remains limited. Methods: Adolescent SMM aged 13-18 years were recruited in three cities (Chicago; New York City; Philadelphia) for interview and HIV testing. We used chi-square tests for percentages of binary variables and one-way ANOVA for means of continuous variables to assess differences by race-ethnicity in behaviors...

Discordance between self-perceived HIV risk and actual risk-taking may impede efforts to promote HIV testing among young adult men-who-have-sex-with-men (YMSM) in the United States (US). Understanding the extent of, and reasons for, the discordance of HIV risk self-perception, HIV risk-taking and voluntary HIV testing among black, Hispanic and white YMSM could aid in the development of interventions to increase HIV testing among this higher HIV risk population. HIV-uninfected 18-24-year-old black, Hispanic, and white YMSM were recruited from across the US through multiple social media websites...

This study used respondent-driven sampling to explore the effects of social support on HIV risk and protective factors among young males who have sex with males (YMSM) in Bangkok (N = 273) and Chiang Mai (N = 243), Thailand. It compared different measures of social support, including living situation, the proportion of family and friends to whom the respondent had disclosed their same-sex attraction, and scores on the multi-dimensional scale of perceived social support as predictors of two outcomes of interest-coerced first sex and HIV knowledge...

The present study addresses gaps in the literature related to theory development for young men who have sex with men (YMSM) sexual practices through the application and modification of Social Action Theory. Data come from the Healthy Young Men study (N = 526), which longitudinally tracked a diverse cohort of YMSM ages 18-24 to characterize risk and protective factors associated with drug use and sexual practices. Structural equation modeling examined the applicability of, and any necessary modifications to a YMSM-focused version of Social Action Theory...

HIV prevention fatigue (the sense that prevention messages are tiresome) and being overly optimistic about HIV treatments are hypothesized to increase HIV risk behavior. Little research has examined these constructs and their correlates among young men who have sex with men (YMSM), who are at high risk for HIV. YMSM (N = 352; Mage = 20; 50% Black) completed measures of prevention fatigue, treatment optimism, HIV risk behaviors, and HIV-related knowledge and attitudes during a longitudinal study. Overall, YMSM reported low levels of HIV prevention fatigue and treatment optimism...

BACKGROUND: HIV/AIDS continues to be a health disparity faced by sexual minority men, and is exacerbated by non-injection drug use. OBJECTIVES: We sought to delineate growth in non-injection drug use and condomless sex in a sample of racially and economically diverse of gay, bisexual, and other young men who have sex with men (YMSM) as they emerged into adulthood between the ages of 18 and 21 and who came of age in the post-HAART era. METHODS: Behavioral data on drug use and condomless sex, collected via a calendar based technique over 7 waves of a cohort study of 600 YMSM, were analyzed using latent growth curve modeling to document patterns of growth in these behaviors, their associations, and the extent to which patterns and associations are moderated by race/ethnicity and socioeconomic status...
