  • Article: Changes in Developmental Contexts as Predictors of Transitions in HIV-Risk Behaviors Among Young Men Who Have Sex with Men (YMSM).
    [show abstract] [hide abstract]
    ABSTRACT: Emerging adulthood is a transitional time often marked by instability in many areas of life, including residential status, work, school, and romantic relationships. The purpose of this study is to examine transitions in HIV-risk related behaviors among a cohort of ethnically-diverse young men who have sex with men (YMSM) and to reveal how changes in developmental contexts during emerging adulthood might be associated with these behavioral changes. Hidden Markov models were used to examine movement across different stages of behavioral risk-taking over time. Semi-annual surveys were administered across 2 years; analyses included those with at least three of the five waves of data. Results indicated substantial movement at the individual-level transitions. Additionally, high variability in sexual risk, alcohol misuse, and illicit drug-risk behaviors was predicted by age, ethnicity, and correlates of emerging adulthood, such as residential status, work, post-secondary school enrollment, and primary-relationship status. Findings provide evidence of great change in risky behaviors among YMSM during this pivotal time, particularly among those who actively experiment in varying levels of risk-taking. In order to prevent experimental behaviors from evolving into more serious risk, interventions must consider ways to assist YMSM to adjust to life changes brought on by emerging adulthood.

  • Article: HIV Prevention Service Utilization in the Los Angeles House and Ball Communities: Past Experiences and Recommendations for the Future.
    [show abstract] [hide abstract]
    ABSTRACT: African-American young men who have sex with men and transgender persons are at elevated risk for HIV infection. House and Ball communities, networks of mostly African-American gay, bisexual, and transgender individuals who compete in modeling and dance, represent a prime venue for HIV prevention with these difficult-to-reach populations; however, little research exists on effective approaches to HIV prevention within these communities. Using a mixed-methods approach, the present study sought to document participation in HIV prevention activities of a sample from the Los Angeles House and Ball communities (n = 263) in order to inform future service development. While 80% of participants were tested for HIV within the past 6 months, only 26% report HIV prevention program attendance. House leaders recommend a holistic approach to HIV prevention, one that incorporates attention to social problems beyond HIV, including poverty, housing difficulties, and lack of job training.

  • Article: A profile of nonurgent emergency department use in an urban pediatric hospital.
    [show abstract] [hide abstract]
    ABSTRACT: This study was designed to develop a descriptive profile of parents and caregivers who bring their children to the emergency department (ED) for nonurgent issues and to explore the reasons for presenting to an urban hospital pediatric ED for nonurgent conditions. Such work is necessary to develop effective interventions. A total of 106 parents/caregivers whose child was triaged with a nonemergent/urgent condition completed a 15- to 20-minute computerized survey (English and Spanish) in an urban pediatric ED. Most respondents described themselves as Latino (76%) and foreign born (62%). About one half (49%) reported having an annual income of less than $20,000, and 43% of respondents did not have health insurance for themselves. Almost all (95%) of the index children had a primary care physician and health insurance. Despite being triaged as nonurgent, more than one half (63%) described their child's condition as "very" or "extremely" urgent. About one half of the respondents reported not receiving basic information on childhood illnesses from their child's physician. Reasons for nonurgent visits seemed to revolve around issues of convenience and perception of quality of care. Interventions should focus on health literacy and ensure that parents are provided relevant and accurate education on pediatric illnesses and common safety concerns; by increasing parental education on pediatric health, parents may be better able to assess acuity of their child's health issues.

  • Article: Environmental risk, social cognition, and drug use among young men who have sex with men: Longitudinal effects of minority status on health processes and outcomes.
    [show abstract] [hide abstract]
    ABSTRACT: BACKGROUND: Young men who have sex with men (YMSM) continue to be at elevated risk for substance use; however, models explaining this phenomenon have often focused on a limited array of explanatory constructs. This study examined the longitudinal relationship of contextual risk factors, social cognitive processes, mental health, and health protective behavior to identify key mechanisms of illicit drug use of YMSM as they aged through emerging adulthood. METHODS: Our sample included an ethnically diverse cohort of 487 YMSM recruited through venue based probability sampling in Los Angeles. We used latent growth curve modeling to understand relationships between environmental risk factors, changing individual and social process variables, health protective behavior, psychological distress, and illicit drug use outcomes among YMSM. RESULTS: Age, ethnicity, violence and discrimination, depression, and previous histories of illicit drug use were key elements of risk for future illicit drug use among YMSM. During this theoretically distinct time period, health as a value, self-efficacy, and social support are vital social cognitive processes for promoting self-change among YMSM, and YMSM have independent growth within each process. Health as a value, self-efficacy, and social support were dynamic social cognitive processes, which served as key mechanisms by which risk factors were converted into health promotion strategies or psychological distress, and ultimately illicit drug use. CONCLUSIONS: The efficacy of prevention interventions aimed at reducing illicit drug use among YMSM can be enhanced by addressing social cognitive processes for this underserved portion of the male population.

  • Article: Laying the Groundwork for an HIV Prevention Intervention: A Descriptive Profile of the Los Angeles House and Ball Communities.
    [show abstract] [hide abstract]
    ABSTRACT: African American young men who have sex with men (AAYMSM) represent the largest proportion of new HIV infections among MSM. While evidence-based interventions are lacking, all too often HIV interventions are implemented in a community without thoroughly understanding its needs, risks and assets. AAYMSM are not homogenous; subgroups exist that may require different approaches to be effective. The House and Ball communities represent one such subgroup. A community-engaged, mixed-methods approach was used. Participant observations, qualitative interviews (N = 26), and a survey at House/Ball events (N = 252) were completed. Survey data broadly describe the community. For example: 69 % of survey respondents identify as gay; 25 % as bisexual; 13 % reported recent use of ecstasy and 11 % recently participated in sex exchange. The depth of qualitative data is key for intervention development. For example, while the survey provides broad descriptions of respondents' involvement in the House and Ball communities, leaders provided in-depth descriptions of the structure of the House and Ball scene-something vital to the development of HIV prevention programs within these communities. This kind of rigorous study is recommended prior to implementing an intervention. Findings are discussed in relation to leveraging the communities' supportive aspects to design culturally relevant HIV prevention programs.

    Article: "It's Like Our Own Little World": Resilience as a Factor in Participating in the Ballroom Community Subculture.
    [show abstract] [hide abstract]
    ABSTRACT: We are well into the third decade of the HIV epidemic. While strides have been made in HIV prevention, rates for African American men who have sex with men (AAMSM) and young AAMSM continue to increase-perhaps indicating that traditional deficit-approaches of HIV prevention are not effective for all populations. Following a recent call to investigate the resiliency of young gay men, this study identifies sources of resilience and strength within the House and Ball communities, a subculture comprised primarily of AAMSM. The mixed-methods design included survey data (N = 263) collected at community events, interviews with Ball attendees and focus group data with House members. Survey data indicate a relationship between participating in the House and Ball communities and seeking support, acceptance and entertainment. Qualitative data validate these findings and provide detail on motivations for AAMSM to participate and the perceived benefits of participation. Findings are discussed in relation to building strengths-based interventions, using concepts of resiliency including shamelessness, social creativity, social support and volunteerism.

  • Article: Community-Engaged Research to Identify House Parent Perspectives on Support and Risk Within the House and Ball Scene.
    [show abstract] [hide abstract]
    ABSTRACT: This article describes a community-engaged study with the Los Angeles House and Ball scene in which the perspectives of the leaders of these communities are captured to better understand how the House and Ball communities may protect or increase its members' risks for HIV infection. Data were collected through in-depth interviews with House parents (N = 26). This study identified key features of both support (e.g., family and support, acceptance, and validation and recognition) and risk (e.g., members' struggles to maintain status in the Ballroom scene, sex work, substance use, danger of becoming too involved in the Ball community, and perception and stigma of the Ballroom scene within the larger gay community) within these communities. Findings are discussed in relation to framing how to leverage the supportive aspects of the House and Ball communities to design relevant HIV-prevention interventions.

  • Article: Use and perceptions of the internet for sexual information and partners: a study of young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: The Internet has opened many doors with its accessibility to information, entertainment and web-based communities. For young men who have sex with men (YMSM), the Internet can provide access to information on relevant sexual behavior and health information, stories from other men about relationship issues, and a venue for locating potential sexual and dating partners. Understanding YMSM's motivations for going online for information, advice or sexual relationships, is important as the Internet becomes increasingly used not only as a space to find sexual partners, but also as a venue for HIV and STI interventions. Having an understanding of the risks associated with searching for partners online, and how and why YMSM use the Internet for a variety of purposes, can inform the development of more effective Internet-based risk reduction programs. This article presents qualitative and quantitative data from the Healthy Young Men's Study, a longitudinal study of an ethnically diverse cohort of 526 YMSM. Qualitative interviews (N = 24) described not only the prevalence of using the Internet for finding sexual partners and the possible benefits and risks associated with that practice, but also the processes and perceptions of using this mechanism. Our data indicate that YMSM used the Internet to find information related to sex and sexuality, seek friendships, sexual partners as well as "hook-ups" or casual sex. Findings were presented in relation to how YMSM researchers and interventionists can identify how to most effectively reach YMSM through online methods.

    Article: Photovoice as a tool to adapt an HIV prevention intervention for African American young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: Objective. HIV rates for African American young men who have sex with men (AAYMSM) have reached as much as 14.7%, compared with 2.5% and 3.5% among Caucasian and Latino YMSM. However, there remains a lack of HIV prevention interventions for this population. This study describes the use of Photovoice in the adaptation process of an evidence-based intervention (Adult Identity Mentoring) to make it developmentally and culturally appropriate for AAYMSM. Method. A total of 36 AAYMSM (aged 18-24 years) participated in weekly working group sessions to conduct a community-, youth-, and data-driven adaptation process. Photovoice was used as a technique to facilitate guided discussions on topics that were identified for the new curriculum. Results. Through Photovoice discussions, we identified a new focus for the adapted intervention, Young Men's Adult Identity Mentoring (YM-AIM): development and maintenance of healthy intimate relationships. This new focus and the resulting curriculum are rooted in the voices and perceptions of the target population. Conclusions. Including youth was integral to the adaptation process and the use of techniques such as Photovoice helped ensure that the resulting adaptation was relevant to the target population.

  • Article: Harassment, discrimination, violence, and illicit drug use among young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: We examined the relationship among social discrimination, violence, and illicit drug use among an ethnically diverse cohort of young men who have sex with men (YMSM) residing in Los Angeles. Five Hundred twenty-six YMSM (aged 18-24 years) were recruited using a venue-based, stratified probability sampling design. Surveys assessed childhood financial hardship, violence (physical assault, sexual assault, intimate partner violence), social discrimination (homophobia and racism), and illicit drug use in the past 3 months. Analyses examined main and interaction effects of key variables on drug use. Experiences of financial hardship, physical intimate partner violence and homophobia predicted drug use. Although African American participants were less likely to report drug use than their Caucasian peers, those who experienced greater sexual racism were at significantly greater risk for drug use. Racial/ethnic minority YMSM were at increased risk for experiencing various forms of social discrimination and violence that place them at increased risk for drug use.

  • Article: Deconstructing the complexity of substance use among young men who have sex with men (YMSM) by optimizing the role of qualitative strategies in a mixed methods study.
    [show abstract] [hide abstract]
    ABSTRACT: Qualitative data can be a powerful tool in developing interventions for substance use and other HIV-risk behaviors. Mixed methods design offers researchers the ability to obtain data that provides both breadth and depth to their research questions. However, the integration of qualitative data in mixed methods research has been limited. This paper describes the qualitative study design of the Healthy Young Men's Study, a longitudinal mixed method study with an ethnically diverse cohort of young men who have sex with men (YMSM) (N = 526) in Los Angeles. Integral to this discussion is how a mixed methods study can address common challenges such as sampling, representation and integration of both datasets.

  • Article: The Healthy Young Men's Study: Sampling Methods to Recruit a Random Cohort of Young Men Who Have Sex with Men.
    [show abstract] [hide abstract]
    ABSTRACT: Recruiting a scientifically sound cohort of young men who have sex with men (YMSM) is an enduring research challenge. The few cohort studies that have been conducted to date on YMSM have relied on non-probability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their generalizability to broader YMSM populations is limited.In this paper the authors describe a venue-based sampling methodology used to recruit a large and diverse cohort of YMSM from public venues in Los Angeles County. Venue-based sampling is a multi-stage, probability sampling design that uses standard outreach techniques and standard survey methods to systematically enumerate, sample, and survey hard-to-reach populations. The study design allowed the authors to estimate individual, familial and interpersonal psychosocial factors associated with HIV risk and health seeking behaviors for a cohort of YMSM with known properties. Study participants completed an extensive baseline survey and over a two year period will complete four follow-up surveys at six-month intervals. The baseline survey was administered in both English and Spanish.

  • Article: "God Made me Gay for a Reason": Young Men who have Sex with Men's Resiliency in Resolving Internalized Homophobia from Religious Sources.
    [show abstract] [hide abstract]
    ABSTRACT: Research investigating the role of religion in the lives of young men who have sex with men (YMSM) is limited. Given the unique developmental stage of emerging adults and the fact that most religions have restrictions on homosexual behavior, it is important to understand how YMSM integrate their sexual and religious/spiritual identities. Drawing upon a longitudinal, mixed methods study, we explore the role of religion and spirituality in the lives of a sample of YMSM. Presented are descriptions of messages about homosexuality from religious contexts and how these messages are internalized. The process used to resolve the conflict between these messages and their sexual identity is then described. Findings discuss how to help YMSM retain the more supportive and nurturing aspects of religion to integrate their sexual and religious identities for a functional support system.

  • Article: In the dark: young men's stories of sexual initiation in the absence of relevant sexual health information.
    [show abstract] [hide abstract]
    ABSTRACT: A growing body of research has investigated the effectiveness of abstinence-only sexual education. There remains a dearth of research on the relevant sexual health information available to young men who have sex with men (YMSM). Drawing on a mixed-methods study with 526 YMSM, this study explores how and where YMSM receive relevant information on sexual health/behavior. Findings indicate that information related to gay men's sexuality is not readily available from family, friends, or schools. At initiation of anal intercourse, respondents generally had limited information about HIV and sexually transmitted infections (STIs). In some cases, this resulted in the perception that activities such as unprotected sex were "low risk." Many mentioned they first learned about anal sex during their sexual debut, describing painful and/or unpleasant experiences. Some relied on older/more experienced partners, the Internet, and pornography for information. Findings are discussed in relation to how providers can help YMSM build solid foundations of sexual education to protect them from STI and HIV infection.

  • Article: Strategies Used by Gay and Bisexual Young Men to Cope with Heterosexism.
    [show abstract] [hide abstract]
    ABSTRACT: Although the pervasiveness of heterosexism in the lives of gay and bisexual youth is well established, little is known about the strategies these youth use to cope with stigma and discrimination based on their sexual minority status. In this qualitative study, the authors present findings and implications for clinical practice based on interviews with 43 gay and bisexual young men. Respondents' coping strategies are discussed in relation to current theory and research on coping with stigma, as well as the emerging field of emotion regulation. The narratives from the current study suggest that the emotion regulation paradigm is well suited to understanding the functions of strategies for coping with heterosexism and similar types of stigma.

  • Article: Risk factors for alcohol use, frequent use, and binge drinking among young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: We examined the prevalence and patterns of alcohol use within a large, ethnically diverse sample of young men who have sex with men (YMSM) and identified psychosocial correlates of these alcohol-use patterns. A sample of 526 YMSM (ages 18-24 years) was recruited in Los Angeles, CA using a venue-based, stratified probability sampling design. Based on criteria used by previous research with young adults, participants were assigned to one of four alcohol-use/non-use groups according to frequency and number of drinks per sitting in the last 30 days. Findings revealed a high prevalence of alcohol use (91%) within the sample, with 21% reporting binge drinking; of binge drinkers, 40% reported frequent binge drinking. Multinomial logistic regression analyses revealed that race/ethnicity, gay bar attendance, depression, sensation seeking, peer risk behaviors, and age of alcohol initiation significantly differentiated between non-/light users from frequent and binge drinkers. Results also indicated unique psychosocial profiles among frequent/binge drinkers. The heterogeneity of predictors associated with different patterns of alcohol use highlights the need to consider unique risk profiles and alcohol-use trajectories according to exposure to different risk and protective factors.

  • Article: Integrating professional and folk models of HIV risk: YMSM's perceptions of high-risk sex.
    [show abstract] [hide abstract]
    ABSTRACT: Risks associated with HIV are well documented in research literature. Although a great deal has been written about high-risk sex, little research has been conducted to examine how young men who have sex with men (YMSM) perceive and define high-risk sexual behavior. In this study, we compare the "professional" and "folk" models of HIV risk based on YMSM's understanding of high-risk sex and where and how they gathered their understanding of HIV risk behaviors. The findings reported here emerged from the quantitative and qualitative interviews from the Healthy Young Men's Study, a longitudinal study examining risk and protective factors for substance use and sexual risk among an ethnically diverse sample of YMSM. Findings are discussed in relation to framing how service providers and others can increase YMSM's knowledge of sexual behavior and help them build solid foundations of sexual health education to protect them from sexually transmitted infections and HIV.

  • Article: Young men's perspectives on family support and disclosure of same-sex attraction.
    [show abstract] [hide abstract]
    ABSTRACT: Young men who have sex with men (YMSM) face myriad challenges when deciding to disclose their sexual orientation to family members. Key to this decision is consideration of how disclosure may influence the support they receive from family. This paper explores a diverse sample of YMSM's (N = 43) perspectives on disclosure of their same-sex attractions to key family members and its impact on family support. Several stages/categories of disclosure are described and some YMSM seemed to continue to move between categories. Additionally, relationships after disclosure included negotiations between the expression of their sexual orientation and the maintenance of family support.

  • Article: Space: the new frontier in HIV prevention for young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: Young men who have sex with men (MSM) in urban areas of the United States continue to be vulnerable to HIV infection. Qualitative data collected with participants in a community level HIV intervention in West Hollywood and Orange County, California, suggest that space -- both actual physical space and the concept of having space -- should be an integral part of an HIV prevention intervention for young MSM. Having such spaces appears to contribute to youth sense of empowerment and efficacy and foster community building, all important components of an effective HIV prevention. Data were drawn from a qualitative research sample of 73. Through narratives, young men describe specific characteristics of the space necessary for effective HIV intervention, including mentoring and supportive staff, tolerant and like-minded peers, information exchange, opportunities for strengthening self-esteem, and a sense of collaborative community invested in social change.

  • Article: Residential status as a risk factor for drug use and HIV risk among young men who have sex with men.
    [show abstract] [hide abstract]
    ABSTRACT: There is growing behavioral and epidemiological evidence to suggest that young men who have sex with men (YMSM) are at high risk for becoming HIV-infected. Unfortunately, relatively little research has been conducted to examine the range of individual, social, and community-level factors that put these young men at increased risk. To address existing gaps in the literature, the Healthy Young Men's (HYM) Study was launched in Los Angeles to examine the range of factors associated with HIV risk and protective behaviors within an ethnically diverse sample of 526 YMSM recruited using a venue-based stratified probability sampling design. In this paper we present findings that demonstrate that YMSM who experience residential instability, who have been forced to leave their home because of their sexuality, and/or who are precariously housed are at significantly greater risk for drug use and involvement in HIV risk-related behaviors.
