Understanding the Effects of Prostate Cancer on Gay and Bisexual Men

This application is an response to PA-12-113, Research on the Health of LGBTI Populations, which “encourages researchers to investigate new questions related to LGBTI health” with “High priority placed on research on interventions for [LGBTI] individuals.” Survivorship of prostate cancer (PCa) is one such area. Across the lifespan, 1-in-6 gay and bisexual men (GBM) and 1-in-3 mail couples will be diagnosed with PCa, making PCa the most common cancer affecting GBM. yet, almost no research has examined the effects of PCa treatment on GBM’s sexual functioning. Sexual dysfunction is the major sequala of PCa treatment, which is deeply distressing in itself, and negatively impacts quality of life post-treatment, resulting in serious negative mental health outcomes. Recent studies indicate sexual outcomes of PCa treatment are significantly worse of GBM that heterosexual men. Physiological differences between anal sex and vaginal sex likely explain, at least in part, this health outcomes, and research to guide development of new treatments tailored to GBM and sex between men.

The long-term objective of this research is to develop the first evidence-based PCa rehabilitation curriculum tailored for GBM. As a first step, in this R21 we will conduct the formative research needed to estimate the extent of poor outcomes, confirm need, and assess acceptability and feasibility. There are three specific aims. In Aim 1, we will investigate, in-depth, the experience of PCa treatment on the sexual lives of GBM, their partners, and their relationships. We will conduct a semi-structured, chat or phone interview study of up to 48 GBM PCa patients, partners, and couples, nationally. In aim 2, we will refine definitions and develop the measures needed to assess sexual dysfunction in GBM. In Aim 3, we will conduct an online quantitative survey of 220 GBM with PCa, which will a) quantify sexual challenges post-treatment, b) assess needs and priorities for rehabilitation, c) develop a new scale to measure sexual functioning in GBM and d) assess the acceptability and feasibility of a new rehabilitation curriculum for GBM with PCa.

Men’s INTernet Study III (MINTS-III) for HIV Prevention

This study is a randomized controlled trial of Sexpulse – an online HIV prevention intervention for men who use the Internet to seek sex with men. It will test whether men who are randomized to receive the intervention engage in less unsafe sex at follow-up than men who do not go through the program.  This three-year project focused on Internet-using Latino Men who have Sex with Men (MSM). At 32 months into the study, we completed an entirely online survey study to assess the Internet-sex risk of Latino MSM in the US, developed a psychosexual profile based on 1,026 participants and compared their risk behaviors in sexual liaisons from the Internet and from conventional meetings.

MINTS-I was followed in 2005 by MINTS-II, where we developed Sexpulse 1.0, an online HIV prevention intervention.  Based on a needs assessment of 2,716 Men who use the Internet to seek Sex with other Men (MISM), Sexpulse 1.0 incorporated fourteen highly interactive modules based on persuasive computing principles.  With 650 total participants, the intervention group showed a statistically significant 16% reduction in risk behavior at 3 months compared to the control.  These key findings, combined with reports of a high number of sexual partners met specifically through the Internet, predict disproportionate infection through liaisons developed online.

These results have compelling implications for all MISM, but variation in sexual risk behavior has shaped the rationale for our next intervention, the Men’s INTernet Study III for HIV Prevention (MINTS-III).  MINTS-III will take the next logical steps in this research:

  • strengthening the intervention to produce long-term behavioral change
  • undertaking a rigorous study of measuring sexual risk online
  • testing the new intervention in two populations (as a risk-reduction intervention with high-risk MISM, and as a risk-protection intervention with no/low-risk MISM)
  • identifying and studying respondent bias in online HIV trials

To accomplish these goals, MINTS-III will involve the next generation of Sexpulse 1.0 and includes five aims:

  • Increase the long-term HIV prevention effectiveness of the intervention
  • Study the temporal reliability and validity of measuring sexual risk behavior online
  • Test the risk reduction efficacy of Sexpulse 1.1, and of online boosters for MISM engaged in high risk behavior
  • Study panel conditioning in online trials
  • Test the protective efficacy of Sexpulse 1.1, and of online boosters for MISM engaged in no/low risk behavior

Internet-based HIV Prevention for Methamphetamine-Using MSM: Formative Research

Methamphetamine-using men who have sex with other men (MUMSM) have double or triple the probability of engaging in unprotected sexual behaviors.  This population may not perceive traditional condom-based prevention messages as options for HIV/STI prevention; therefore, a harm reduction approach has the potential to reinvigorate HIV prevention for this community.  Of particular concern in this context is the complex interplay between polysubstance use and use of the Internet to meet sexual partners with subsequent risk behaviors.

The long-term objective of this study is to develop a technology-based tool for MUMSM and educators serving this population that will facilitate a reduction in HIV transmission by supporting the enactment of harm reduction strategies, including but not limited to increased condom use.

Grounded in the Information-Motivation-Behavioral Skills (IMB) Model for health education and promotion, there are four aims of this study:

  • Comparing patterns of polysubstance use and harm reduction in MUMSM who meet male sexual partners online to identify differences in IMB and predictors of risk behavior
  • Identifying how MUMSM in different harm reduction classifications vary in their perception of online HIV prevention needs, including preferred content and design features
  • Identifying perceived online HIV-prevention needs, including preferred content and design features, of HIV-prevention educators who regularly conduct outreach and education for MUMSM
  • Integrating quantitative and qualitative data to identify the IMB content and design features of an online HIV intervention for MUMSM

This kind of research is particularly important because a mobile online intervention brings prevention to the risk environment where MUMSM are meeting men for substance use and sexual encounters.  It can also provide educators and case managers ways to stay in touch with hard-to-reach MSM.

Internet-Based HIV Prevention for Indian MSM

Internet use in India is in a period of rapid expansion and holds enormous potential for reaching stigmatized men at high risk of HIV infection with effective prevention education. To date, Internet-based HIV-prevention research and interventions have not been studied. With this study, we propose to begin addressing this gap in research.

This is a bilateral collaborative study which has been funded by the National Institute of Allergy and Infectious Diseases (NIAID) and the Indian Council of Medical Research (ICMR). Our team includes HIV prevention Internet researchers from the University of Texas Health Science Center and the University of Minnesota, as well as researchers with expertise in HIV prevention targeting high-risk men in Mumbai from The Humsafar Trust, the Tata Institute of Social Sciences, and the University of California, San Francisco.

There are four aims of this study:

  • Documenting how the Internet is used to meet male sex partners and test the feasibility of conducting online focus groups to reach high-risk men
  • Conducting a usability assessment to determine the cultural appropriateness of an evidence-based Internet intervention for high-risk men in Mumbai
  • Conducting a technology and virtual environment assessment
  • Conducting an online behavioral risk and needs assessment

All procedures mirror work successfully completed by the HIPS team in the US. These procedures have been adapted to research the Indian context and epidemic. Hence this study will test methods untried in India. The primary significance of this study includes its potential public health impact in averting HIV infections among high-risk men in India. An online intervention in India has the potential to reach thousands of men, reduce risky beliefs and behaviors, and prevent the spread of HIV.

Completed Research

Among Men is a modular program delivered online and in person that educates and supports men at the group level – helping them develop a greater sense of confidence and belonging around their sexuality and sexual behaviors.

It is designed for men of all ages and races who have sex with men – or are thinking about having sex with men. Our participants come from all walks of life and include men who are questioning their sexuality, those who are out, men who are HIV negative and those who are HIV positive. Created and maintained at the University of Minnesota, the program is designed to be delivered through community organizations in a flexible format that best supports their members.

Among Men is an outgrowth of the University of Minnesota’s Man2Man program (now retired). Our new curriculum is a response to the changing needs of men’s lives. In an effort to keep up with the times we have restructured and are bringing Among Men to the community by working with partners on developing customized events.

We work closely with community organizations, university groups, churches and HIV/AIDS care organizations to deliver these programs. Explore the Community Partners section for more details on how to become involved.

Internet Medication Adherence Study (IMAS)/Thrive! – Living with HIV Study

The HIV epidemic continues to be a significant public health threat in the United States. As individuals living with HIV live longer due to improved treatments, understanding the experiences of living with HIV across the lifespan is critical. The objectives of this study are to:

  1. Understand people living with HIV’s physical and mental health and their strategies for healthy living, and
  2. Understand people living with HIV’s use of the Internet

The primary objective of Man2Man (M2M) is to provide an innovative, evidence-based, high-quality, intensive, community- and risk-appropriate HIV risk reduction intervention. This is provided directly to the community most infected and affected by HIV in the U.S., gay, bisexual and other men who have sex with men (MSM). The aim of this two-day, seminar-based program is to reduce MSM’s HIV sexual risk behavior and sexual co-factors, through promoting long-term sexual health. The stated goals of M2M include:

  1. to provide accurate knowledge to assist participants to develop a comprehensive understanding of their own and others’ sexualities;
  2. to challenge attitudes (regarding self-acceptance, sociosexual behavior and HIV/AIDS);
  3. to affirm healthy and responsible lifestyles;
  4. to confront factors and cofactors maintaining unsafe sex, by assisting participants to develop self-esteem to lower internalized homophobia;
  5. to promote assertiveness in participants; and
  6. to build community identification by assisting individuals to identify with similar others.

The seminar is based on a model developed at the University of Minnesota (Robinson et al., 2002), while its effectiveness on sexual behavior was tested in a randomized controlled trial (Rosser et al., 2002). As part of the seminar, participants have the opportunity to participate in research on MSM’s sexual health through pre-test and post-test pen and paper surveys.

To date Man-to-Man has been offered in 3 countries and several states to demonstrate what new programs for gay, bisexual and other MSM can look like. The Man-to-Man curriculum is currently offered in English as Man-to-Man and in Spanish as De hombre a hombre. Currently, Man-to-Man is offered in two U.S. states on a regular basis as a university-community collaboration.

  • In Minnesota, Man-to-Man is being offered in the Twin Cities and annually in rural Minnesota. We partner with the Minnesota AIDS Project in recruiting men for this intervention, while health professionals from over 40 agencies work collaboratively on staffing this physician-sexologist-led seminar.  These seminars are funded through the Minnesota Department of Health.
  • In Arizona, the University of Minnesota partners with Arizona Body Positive who have been implementing the seminars in Phoenix and now statewide. These seminars are funded through the Arizona Department of Health and Human Services.


A BIG welcome to Man-to-Man! This weekend seminar asks gay, bisexual, other men who have sex with men, and men attracted to men, a critical challenge:  “How is my and our sexual health?” Over the two days, you have the opportunity to participate in a seminar led by two health professionals focused on human sexuality and intimacy. Seminar activities include large group presentations, small group discussions, exercises, games, challenges and workbook activities. Because the program is comprehensive, you are strongly recommended to attend the whole seminar.

Please note this seminar includes sexually explicit media and discussions of sex between men. For this reason the seminar is restricted to adults aged 18 years or older.

Goals of the seminar:

  1. To provide accurate knowledge on human sexuality and sexual health
  2. To challenge your attitudes (to assist you to know yourself better)
  3. To affirm healthy and responsible options in sexuality
  4. To provide an experience of sexual health, within which to address concerns
  5. To build community by providing a safe place to challenge sexual health
  6. To promote assertiveness in confronting factors that limit participants adopting sexual health.


  • Learning to be sexually healthy
  • Sexuality across the lifespan
  • Intimacy and stages of gay relationships
  • Bisexuality and sexual diversity
  • Sexual functioning and how to improve a sex life
  • Developing assertiveness and empowerment
  • Breaking isolation and developing networks
  • Understanding effects of fear, violence and abuse
  • Being sexual in the age of HIV and other sexually transmitted infections
  • Sexuality and spirituality

Suggested guidelines for the Weekend

  • Reflect: This is a “retreat” time to reflect on you, your life, and your health. You are encouraged to make it personal, to take “time out,” and relax.
  • Respect: This is also an opportunity to learn from other participants. We encourage an attitude of respect for the differences and similarities.
  • Adult education: Share only what you want to disclose, and participate only as you wish.
  • Enjoy and have fun: We encourage active participation through exercises.

Formative Internet-Based Research to Improve Health and Reduce HIV Transmission among HIV-Positive Persons (the Internet Study).

The Positive Internet Study was a two-year formative research study to inform the future development of an Internet-based sexual risk reduction intervention for persons recently diagnosed with HIV infection (in the past year). Specifically, we propose to conduct qualitative telephone interviews with HIV-positive men and women to identify:

1.Critical social, mental, emotional, informational, and medical needs following their diagnosis that could be addressed in an online format and within which sexual risk reduction messages could be integrated;

2. Personal and technological barriers to seeking and successfully accessing HIV/AIDS-related information on the web; and

3. Features that attracted participants to access and return to websites.

In this study, participants were recruited from offline (e.g., local HIV clinics, AIDS service organizations) and online (e.g., HIV-oriented websites) venues to participate in one-on-one telephone interviews. Both online and offline recruitment venues will be used to ensure that participants represent regional, race/ethnicity, and Internet usage diversity. Adult (18+ years) HIV-positive heterosexually-identified men and women, homosexually-identified men, and male-to-female transgender individuals diagnosed within the last 12 months (prior to enrollment) were interviewed.

The outcomes for this study included a list of topics (e.g., social, mental, emotional, information, medical) relevant to the needs of recently diagnosed HIV-positive individuals and a list of facilitators and barriers that these individuals faced when accessing HIV-related information on the web. This study allowed us to collect a rich data set that will ultimately guide the development of a comprehensive Internet-based HIV risk reduction prevention and health promotion resource for HIV-positive persons in future research.

Positive Connections Study (2003-2008)

After almost a decade of stable HIV infection rates, in 2001, several US cities reported a marked increase in risk taking among men who have sex with men (MSM), as well as a rise in STDs in this population. Of most concern, significant coinfection of STDs were reported in previously diagnosed HIV+MSM. In response, the CDC published two national alerts calling for “immediate action,” and prioritizing prevention and outreach to HIV+MSM as “critical.” Unfortunately, no scientifically validated interventions targeting HIV+MSM has been published. Thus, the purpose of this study was to respond to this crisis by studying how best to target HIV+MSM (separately or with other MSM) and by developing and testing a new intervention to lower HIV+ MSM’s risk behavior (Positive Sexual Health).

We aimed to implement and evaluate the long-term effectiveness of an innovative intervention strategy on the unsafe sex behaviors and risk cofactors of HIV positive men who have sex with men (HIV+MSM). In the first phase of the study, a consultant team of HIV+MSM adapted the content of an existing sexual health intervention for MSM, called Man-to-Man Sexual Health Seminars, to address the specific sexual health concerns, needs and behaviors of HIV+MSM. In the second phase, we conducted two pilots: a pre pilot of the revised curriculum, called Positive Sexual Health, with 30 HIV+MSM, followed by a pilot of the full trial on a sample of 60 HIV+MSM and 20 HIV negative (HIV-) or HIV unsure MSM. Following further refinement, the third phase was a randomized controlled 3 arm trial of intervention efficacy (N=580 HIV+MSM and 216 HIV-/HIV unsure MSM).

In 5 cities where increases in STDs among HIV+MSM had been documented, participants were randomized by racial/ethnicity strata to one of the three arms of the trail: Positive Sexual Health (comprehensive sexual health HIV prevention intervention for HIV+MSM only and tailored to address HIV prevention from an HIV+ person’s perspective), Man-to-Man (a comprehensive sexual health HIV prevention intervention for all MSM) or Men Speaking Out (a 3-hour video control condition). Immediately post-intervention, all subjects completed a survey examining attitudinal change and evaluating the intervention. Participants followed up at 6, 12, and 18 months. Using this design, we aimed to test 2 hypotheses:

1. that at 12 and 18 month follow-up, HIV+MSM who experience the sexual health interventions would report significantly lower rates of unsafe sex and lower scores on the risk cofactors than the control group; and

2. that the sexual health intervention that targeted HIV+MSM exclusively would be significantly more effective at lowering HIV+MSM’s risk behavior than the intervention targeting all MSM.

Structural Interventions to Lower Alcohol-related STI/HIV risk (SILAS)

In the US, HIV prevention targeting Men who have Sex with Men (MSM) appears to be failing, while a syndemic of high alcohol/drug use and unsafe sex is increasing. The Office of AIDS Research at the National Institute of Health (NIH) (FY 2006) has prioritized research that aims to “develop and evaluate methods … to reduce HIV acquisition … associated with drug and alcohol use” while CDC has described finding “new approaches to reduce HIV risk among MSM” as of the “highest” priority. In response, our broad long-term objective is to study the impact of structural interventions likely to reduce Alcohol-Related HIV Risk (ARHR) among MSM. Legislation on homosexuality and the growth of gay e-infrastructure are two such structural factors, which have become prominent national issues, yet little is known about how either impacts MSM’s health and HIV risk behavior.

We theorize that gay bars are the environmental structure most driving heavy alcohol use and ARHR, and thus contribute to male-male transmission of HIV, syphilis and gonorrhea. If so, the growing utilization of gay e-environments should lower risk. Similarly, legislation on homosexuality, by mainstreaming or marginalizing MSM, is predicted to have significant health impact on this population. This project has 2 aims:

  1. To study, at the community level, how public policy and gay e-infrastructure may be changing the centrality and popularity of gay bars;
  2. To study, at the individual level, how public policy and gay e-infrastructure modifies alcohol use and ARHR among Men who use the Internet to seek Sex with Men (MISM).

To implement these aims, we have assembled an interdisciplinary team of researchers in HIV prevention, alcohol, law, computer science, demography, Internet research, and homosexuality. This team will conduct a prospective, case-comparison, natural experiment study in 16 cities with different legislation on homosexuality (8=pro, 8=anti) and different levels of gay e-infrastructure (8=strong, 8=weak). How these factors impact risk will be tracked at two levels, annually, over 4 years:

  1. the city level, by taking a city-wide census of gay bars/clubs, bar attendance, gay e-infrastructure, and HIV/STI rates;
  2. the individual level, by comparing MISM’s (n=250 per city; 4000 per period) alcohol use and ARHR behavior with men first met (a) in gay bars, (b) online, and (c) in neither environment (with participants acting as their own control).

Public Health Relevance:
This study:

  1. advances methods for online behavioral surveillance;
  2. examines how alcohol use impacts HIV risk; and
  3. studies how virtual environments and public policy impact a community’s structure, alcohol use, and HIV risk behavior.

As the first study to examine how legislation and e-infrastructure impacts health of high-risk communities, this study will inform key stakeholders and the public, nationally and internationally, on how law and the e-environment impact health and HIV risk.
