Predictive Models to Identify Factors Associated with a High One-Time Sexual Partnership Rate Among U.S. Men Who Have Sex with Men
The Role of Healthcare-Related Experiences in Willingness and Preference for Long-Acting Injectable PrEP (LAI-PrEP) Among Transfeminine People in the United States
Transgender women and transfeminine people (TWTFP) experience disproportionately high HIV prevalence, low HIV pre-exposure prophylaxis (PrEP) coverage, and negative healthcare experiences. Long-acting injectable PrEP (LAI-PrEP) and daily oral-PrEP are delivered under different healthcare interaction protocols. We examined the role of healthcare-related experiences on willingness and preference for LAI-PrEP among a U.S. nationwide sample of sexual…
Posttraumatic stress disorder symptomology among gay, bisexual, and other sexually minoritized cisgender men in the United States
In the United States, posttraumatic stress disorder (PTSD) disparities among sexually minoritized men (SMM) are well-documented, but diverse PTSD symptom manifestations and related vulnerabilities in this group are understudied. From October 2020 to January 2021, we collected cross-sectional demographic, HIV status, sexual behavior, and mental health data from 6,319 trauma-exposed SMM in the American Men’s Internet Survey. We used latent class an…
Correlation between sexual behavior and preferences for HIV pre-exposure prophylaxis modality among men who have sex with men
Demographic, behavioral, and clinical characteristics have been found to be associated with willingness to use and preferences for different HIV pre-exposure prophylaxis (PrEP) modalities. Limited data are available, however, describing how sexual behavior characteristics affect willingness to use and preferences for PrEP. Given the different clinical characteristics of available PrEP modalities (i.e., daily oral, on-demand oral, long-acting inje…
Mpox stigma during the 2022 outbreak among men who have sex with men in the United States
Mpox emerged on the global scale in 2022 and predominately affected gay, bisexual, and other men who have sex with men (GBMSM). Stigma related to mpox is a potential harm for individuals experiencing multiple levels of marginalization who may already be discriminated against in family, healthcare, and other social domains. To understand perceived mpox stigma among cisgender GBMSM in the United States (US), we conducted a study within the American…

Individual & joint associations of sexual stigma and mental distress with PrEP uptake, adherence and persistence among US gay and bisexual men
The Impact of the Covid-19 Pandemic on Sexual Behavior and HIV Prevention and Treatment Services Among U.S. Men Who Have Sex With Men in the Post-Lockdown Era
Early in the COVID-19 pandemic, disruptions to sexual health services and changes to sexual behavior due to the first COVID-19 lockdowns were common among U.S. gay, bisexual, and other men who have sex with men (GBMSM). Less is known about the persistence of these changes after this initial lockdown period. These changes have long-term implications for HIV prevention for current and future pandemic periods. This study collected information on COV…
Chemsex Drug Use among a National Sample of Sexually Active Men who have Sex with Men, – American Men’s Internet Survey, 2017–2020
Background: Chemsex is the intentional use of drugs to enhance sexual activity. Chemsex drug use among men who have sex with men (MSM) is associated with sexual behaviors that increase sexually transmitted infection (STI) risks and adverse mental health outcomes. However, published data are largely based on MSM recruited from STI clinics. There are limited data about use of chemsex drugs among national samples of MSM in the United States. Using d…
Algorithmic urban planning for smart and sustainable development
In recent years, artificial intelligence (AI) has been increasingly put into use to address cities’ economic, social, environmental, and governance challenges. Thanks to its advanced capabilities, AI is set to become one of local governments’ principal means of achieving smart and sustainable development. AI utilisation for urban planning, nonetheless, is a relatively understudied area of research, particularly in terms of the gap between theory …
Effects of mode of transportation on PrEP persistence among urban men who have sex with men
Little is known about the effect of travel-related factors, such as mode of transportation, on retention in PrEP care, or PrEP persistence. We used data from the 2020 American Men's Internet Survey and conducted multilevel logistic regression to estimate the association between mode of transportation used for healthcare access and PrEP persistence among urban gay, bisexual, and other men who have sex with men (MSM) in the U.S. MSM using public tr…
Assessing the association of stigma and HIV service and prevention uptake among men who have sex with men and transgender women in South Africa

Explaining racial disparities in HIV incidence in black and white men who have sex with men in Atlanta, GA
Applying a PrEP Continuum of Care for Men Who Have Sex With Men in Atlanta, Georgia
Reductions in human immunodeficiency virus (HIV) incidence with pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) will require significant coverage of those at risk. We propose a simplified framework, similar to the HIV care continuum, to achieve protection with PrEP as follows: 1. At-risk MSM; 2. Awareness of and willingness to take PrEP; 3. Access to healthcare; 4. Receiving a prescription; and 5. Adhering to effective PrEP. W…
Perception of community tolerance and prevalence of depression among transgender persons
