Correlates of Syringe Acquisition at Syringe Services Program and Pharmacies among Persons Who Inject Drugs
HIV and Syphilis Seroprevalence and Correlates of HIV-Syphilis Co-infection Among Black and Latina Women of Transgender Experience and Transfeminine People in Los Angeles County, 2023–2024
Brief Report
National HIV Behavioral Surveillance Among Women of Transgender Experience and Transfeminine People in Nine Cities in the United States, 2023–2024
Women of transgender experience and transfeminine people (WTE/TFP) are disproportionately impacted by HIV. Between July 2023 and May 2024, a total of 2059 eligible WTE/TFP across nine project areas participated in the National HIV Behavioral Surveillance (NHBS-Trans) project. Among the 1993 participants with valid HIV test results, 35.7% were living with HIV. Detrimental social and economic factors were common, including low income (57.0%), unemp…
Interest in Long-Acting PrEP by Methamphetamine Use Among Men Who Have Sex with Men in Four Western US Cities
Methamphetamine use is a driver of HIV among men who have sex with men (MSM) and is associated with suboptimal adherence to daily, oral PrEP. Long-acting PrEP may be a promising alternative. We analyzed data from the 2023 National HIV Behavioral Surveillance survey in four western cities to assess interest in long-acting PrEP among HIV-negative MSM participants. Of 1,450 participants, 7% used methamphetamine in the past 12 months. Two-thirds were…

Comparing Socio-Demographics and HIV Testing and Prevention Outcomes Between Low-Income HIV-Negative Heterosexually Active Black Women and Men with Health Insurance
Investigating the relationship between math literacy and linguistic synchrony in online mathematical discussions through large‐scale data analytics
Previous literature has associated math literacy with linguistic factors such as verbal ability and phonological skills. However, few studies have investigated linguistic synchrony , shown in mathematical discussions. This study modelled math literacy and examined the relationship of math literacy with linguistic synchrony between students and facilitators. We retrieved data from 20,776 online mathematical discussion threads at a secondary school…
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-…
Past-Year HIV Testing, Current Antiretroviral Therapy Use, and Participation in Services for People Who Inject Drugs
Factors Associated with Exchange Sex Among Cisgender Persons Who Inject Drugs
Evaluation of Rapid Testing Algorithms for Venue-based Anonymous HIV Testing among Non-HIV-Positive Men Who Have Sex with Men, National HIV Behavioral Surveillance (NHBS), 2017
HIV rapid testing algorithms (RTAs) using any two orthogonal rapid tests (RTs) allow for on-site confirmation of infection. RTs vary in performance characteristics therefore the selection of RTs in an algorithm may affect identification of infection, particularly if acute. National HIV Behavioral Surveillance (NHBS) assessed RTAs among men who have sex with men recruited using anonymous venue-based sampling. Different algorithms were evaluated am…
Racial/Ethnic Disparities in HIV Preexposure Prophylaxis Among Men Who Have Sex with Men — 23 Urban Areas, 2017
National Gay Men's HIV/AIDS Awareness Day, September 27, directs attention to the impact of human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) on gay, bisexual, and other men who have sex with men (MSM). In 2017, MSM accounted for 67% of new diagnoses of HIV infection, and MSM who inject drugs an additional 3% (1).
Changes in HIV Preexposure Prophylaxis Awareness and Use Among Men Who Have Sex with Men — 20 Urban Areas, 2014 and 2017
Human Services proposed a strategic initiative to end the human immunodeficiency (HIV) epidemic in the United States by reducing new HIV infections by 90% during 2020-2030* (1). Phase 1 of the Ending the HIV Epidemic initiative focuses on Washington, DC; San Juan, Puerto Rico; and 48 counties where the majority of new diagnoses of HIV infection in 2016 and 2017 were concentrated and on seven states with a disproportionate occurrence of HIV in rur…
