PrEP Use Among Black Transgender Women
Factors associated with PrEP use in a community sample of African American men who have sex with men (MSM) and transgender women (TGW) in the United States Midwest
Black sexual minority men who have sex with men (MSM) in the United States are at disparate risk for contracting HIV infection, but pre-exposure prophylaxis (PrEP) use is suboptimal. Social network methods were used to recruit a community sample of racial minority MSM and transgender women (TGW) in two Midwestern US cities. 250 PrEP-eligible (HIV-negative) participants completed measures assessing current and intended PrEP use; demographic charac…
Stigma, serostatus disclosure, coping strategies, and the role of social capital resources among HIV care-nonadherent MSM in Russia
The HIV epidemic continues to expand in Russia, with suboptimal levels of care uptake. This qualitative study aimed to characterize social capital resources and lived stigma experiences, coping, and disclosure among care-nonadherent men who have sex with men (MSM) living with HIV in Russia. Twenty-five HIV-positive MSM - recruited online - completed in-depth interviews over Zoom, with data analyzed using MAXQDA software. Stigma was more likely to…
That’s My Girl; I love her”
Hometown Heroes
Coronavirus disease 2019 (COVID-19) created life-disrupting stressors that disproportionately burden disadvantaged communities with devastating impacts that extend far beyond the burden of the disease itself, including joblessness, housing and food insecurity, educational system upheavals, isolation due to disrupted relationships, worsened mental health and substance use and violence. Socially interconnected community members are resources whose …
Using a novel genetic algorithm to assess peer influence on willingness to use pre-exposure prophylaxis in networks of Black men who have sex with men
The DeGroot model for opinion diffusion over social networks dates back to the 1970s and models the mechanism by which information or disinformation spreads through a network, changing the opinions of the agents. Extensive research exists about the behavior of the DeGroot model and its variations over theoretical social networks; however, research on how to estimate parameters of this model using data collected from an observed network diffusion …
Performance of a Genetic Algorithm for Estimating DeGroot Opinion Diffusion Model Parameters for Health Behavior Interventions
Leveraging social influence is an increasingly common strategy to change population behavior or acceptance of public health policies and interventions; however, assessing the effectiveness of these social network interventions and projecting their performance at scale requires modeling of the opinion diffusion process. We previously developed a genetic algorithm to fit the DeGroot opinion diffusion model in settings with small social networks and…
Social network intervention to increase pre-exposure prophylaxis (PrEP) awareness, interest, and use among African American men who have sex with men
In the U.S., HIV incidence is highest among Black men who have sex with men (MSM) but PrEP uptake is low, in part due to lack of normative support for using PrEP. This research pilot tested a social network-level intervention designed to increase PrEP use willingness, interest, and peer supports among Black MSM in Milwaukee. Five community social networks (n = 40 participants) of racial minority MSM were assessed at baseline with measures of PrEP…
Mobilizing individual social capital resources for HIV care support
Half of HIV-positive persons in Russia are on antiretroviral therapy (ART), and only 27% are virally suppressed. A feasibility pilot intervention to mobilize social capital resources for HIV care support was conducted in St. Petersburg. Out-of-care or ART-nonadherent HIV-positive persons (n = 24) attended a five-session intervention to increase access social capital resources (i.e., family, friends, or providers) to mobilize supports for entering…

The Health and Sociocultural Correlates of Aids Genocidal Beliefs and Medical Mistrust Among African American MSM
Correlates of Sexual HIV Risk Among African American Men Who Have Sex With Men
Objectives. We examined correlates of condomless anal intercourse with nonmain sexual partners among African American men who have sex with men (MSM). Methods. We recruited social networks composed of 445 Black MSM from 2012 to 2014 in Milwaukee, Wisconsin; Cleveland, Ohio; and Miami Beach, Florida. Participants reported past-3-month sexual behavior, substance use, and background, psychosocial, and HIV-related characteristics. Results. Condomless…

Programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean
This study assessed the programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in 75 countries in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean. Multiple databases and expert recommendations were used to identify one major HIV-prevention NGO in the capital or a large city in each country, and in-depth interviews were conducted with each NGO Director. Most NGOs are carrying out th…
Identifying, recruiting, and assessing social networks at high risk for HIV/Aids
Population segments at highest risk for HIV are often hidden, marginalized, and hard to reach by conventional prevention programmes. This pattern is especially true in Central and Eastern Europe, where major HIV epidemics have recently appeared, where population members do not perceive themselves as belonging to a community, and where there is little precedence for strong community-based organization service programmes. In these circumstances, na…

HIV risk characteristics and prevention needs in a community sample of bisexual men in St. Petersburg, Russia
A new and understudied HIV epidemic is quickly unfolding in the Central and Eastern European countries of the former Soviet Union. Men who have sex with men (MSM) in Russia constitute a population highly vulnerable to sexually-transmitted HIV infection. In a community sample of 434 Russian MSM accessed in gay venues in St. Petersburg, 126 had had both male and female partners in the past three months. In this paper, we report on their risk charac…
Gender roles and HIV sexual risk vulnerability of Roma (Gypsies) men and women in Bulgaria and Hungary
Roma, the largest ethnic minority group in Central and Eastern Europe, have cultures that are traditional, often closed, and autonomous of majority populations. Roma communities are characterized by pervasive social health problems, widespread poverty, limited educational opportunities, and discrimination. Although some evidence suggests high levels of HIV sexual risk behaviour among Roma, little is known about the cultural and social context in …
