“I think PrEP would be magnificent”
Guatemala is a religious and socially conservative country with one of the largest Indigenous populations in the world. Indigenous communities have experienced centuries of discrimination, resulting in persistent health and economic disparities. In addition, Guatemala lacks legal protections for sexual minorities, placing Indigenous sexual minorities at heightened risk for adverse health outcomes, including HIV. This study explores Indigenous gay…

Examining the Association Between Violence and PrEP Use Among Indigenous Gay and Bisexual Men in Guatemala
Indigenous gay and bisexual men (GBM) in Guatemala face high rates of violence and HIV. This study seeks to understand the relationship between exposure to different forms of violence and PrEP use to inform PrEP programming in Guatemala. From June 2023- May 2024, two partner organizations administered a cross-sectional questionnaire to 395 Indigenous Guatemalan GBM. We examined the relationship between violence (physical, sexual, and police viole…
Cultural adaptation, translation, and validation of the Measure of Indigenous Racism Experiences Scale for Indigenous gay and bisexual men in Guatemala
Introduction Among Indigenous communities, racism is associated with negative health effects, including worsened physical and mental health outcomes and less engagement with health services. Despite nearly half of Guatemalans identifying as Indigenous, there have been no scales developed and validated to measure self-reported racism in Indigenous populations in Guatemala, nor elsewhere in Latin America. This study validates the Measure of Indigen…
Key Storytellers of Health Information Among Spanish-Speaking Latino Sexual Minority Men in the U.S
This study sought to identify the primary sources of HIV and health information among Spanish-speaking Latino gay, bisexual, and other sexual minority men (SMM) in the United States (U.S.) and assess the strengths and limitations of their storytelling networks. We explored how storytellers, or those who relay information to individuals and communities, act as facilitators or barriers to HIV prevention and care services. We conducted individual se…
Doblemente tachada
Although nearly half of Guatemalans identify as Indigenous, little is known about the unique health experiences of Indigenous sexual minority individuals. We sought to explore how intersectional stigma impacts the health of Indigenous gay and bisexual men (GBM) in Guatemala. Between February and May 2021, we conducted in-depth qualitative interviews via Zoom with key stakeholders (n = 12) working with Indigenous GBM throughout Guatemala. We coded…

BACKGROUND: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 cou…
Sexual behavior stigma among cisgender gay, bisexual, and other men who have sex with men in nine NHBS cities across the United States
In the United States (US), sexuality-based stigma continues to undermine HIV prevention and care efforts. We assessed sexual behavior stigma burden across family, healthcare, and social domains and determined associations with HIV-related outcomes among cisgender gay, bisexual, and other men who have sex with men (MSM) in nine US metropolitan statistical areas. MSM ( N = 4,086) recruited at places of MSM social congregation via venue-based, time-…

Discriminatory distress, HIV risk behavior, and community participation among American Indian/Alaska Native men who have sex with men
Objectives Research regarding men who have sex with men (MSM) indicates that exposure to discrimination based on race and sexuality are positively associated with increased incidence of unprotected anal intercourse (UAI). In an effort to better understand this association, we assessed the associations of discriminatory distress with UAI among a sample of 183 American Indian and Alaska Native (AI/AN) MSM using survey data drawn from the HONOR Proj…
Self-Implemented HIV Testing
We examined the potential for increasing the reach of HIV testing to African American youths through the dissemination of oral-HIV testing. From 2012 through 2013 we examined the perceptions of alternatives to pharmacy dissemination of SITs in African American youths (5 focus groups) and service providers (4 focus groups), and conducted an ethnographic study of pharmacies (n = 10). Participants perceived significant advantages to delivering SITs …
Nonprobability and Probability-Based Sampling Strategies in Sexual Science
With few exceptions, much of sexual science builds upon data from opportunistic nonprobability samples of limited generalizability. Although probability-based studies are considered the gold standard in terms of generalizability, they are costly to apply to many of the hard-to-reach populations of interest to sexologists. The present article discusses recent conclusions by sampling experts that have relevance to sexual science that advocates for …
Structural Determinants of Indigenous Health
Indigenous populations in the Americas carry a disproportionate burden of disease. Common to populations affected by health inequities is the exposure to structural factors—social, political, environmental and economic—that shape the risks for disease. We conducted a photovoice study in three Shipibo-Konibo indigenous villages in the Peruvian Amazon. Twenty-four indigenous participants consented to take part. The study found that Shipibo-Konibo v…
Sex Trading and Other HIV Risks among Drug-Involved Men
This study examined the prevalence of childhood sexual abuse (CSA), sex trading, and other HIV risks among a random sample of 356 men in heterosexual relationships who were enrolled in methadone treatment in New York City. Mediational analyses were performed to test a hypothesis that selected dimensions of substance use history and psychopathology mediate the relationship between CSA and sex trading and HIV risks. Thirty-eight percent ( n = 135) …

The Sex Check
The Sex Check is a brief, telephone-delivered, HIV-prevention intervention tailored for individuals who are at high risk of HIV infection or transmission but who are neither reducing their risk on their own nor seeking support for this purpose. Because the intervention is delivered on a one-to-one basis, permits anonymity, is marketed to "men who have sex with men," and is brief, it may be particularly responsive to cultural, structural, and atti…
