Variation in Preferences for Long-Acting Injectable Pre-Exposure Prophylaxis Among US Men Who Have Sex with Men: A Latent Class Analysis.

Cabotegravir long-acting injectable HIV pre-exposure prophylaxis (LA PrEP) is efficacious, with a good safety profile, and was approved by the US Food and Drug Administration in December 2021. Understanding variations in potential user preferences for LA PrEP may inform implementation and subsequently improve uptake and community-level effectiveness. HIV-negative, sexually active men who have sex with men (MSM) aged ≥15 years were recruited online for the 2019 American Men's Internet Survey, before LA PrEP approval. Respondents completed a discrete-choice experiment (DCE) with hypothetical LA PrEP attributes (out-of-pocket cost, perceived side effects, injection frequency, perceived stigma, service location). Latent class analysis segmented respondents into groups based on their preferences for the attributes presented, and relative importance of preference weights and willingness-to-pay were calculated. While the majority had never used daily oral PrEP, 73% of the 2489 respondents were very or somewhat likely to use LA PrEP. Three latent classes were identified from 2241 respondents in the DCE. The "side effects-averse" class was the largest group (64% of respondents) and placed 61% relative importance on side effects. The "ambivalent" class (20% of respondents) placed higher importance on stigma (17% of relative importance) than other classes. The "cost-conscious" class (16% of respondents) placed higher relative importance (62%) on cost compared with other attributes and classes. Perceived side effects were an important hypothetical barrier for LA PrEP uptake among a large proportion of potential MSM users. Minimizing out-of-pocket costs is likely to increase uptake and may be important to equitable access. Tailored communication strategies are recommended for the different groups of potential LA PrEP users.

Characterizing the Impact of COVID-19 on Men Who Have Sex with Men Across the United States in April, 2020.

The COVID-19 pandemic is reinforcing health inequities among vulnerable populations, including men who have sex with men (MSM). We conducted a rapid online survey (April 2 to April 13, 2020) of COVID-19 related impacts on the sexual health of 1051 US MSM. Many participants had adverse impacts to general wellbeing, social interactions, money, food, drug use and alcohol consumption. Half had fewer sex partners and most had no change in condom access or use. Some reported challenges in accessing HIV testing, prevention and treatment services. Compared to older MSM, those 15-24 years were more likely to report economic and service impacts. While additional studies of COVID-19 epidemiology among MSM are needed, there is already evidence of emerging interruptions to HIV-related services. Scalable remote solutions such as telehealth and mailed testing and prevention supplies may be urgently needed to avert increased HIV incidence among MSM during the COVID-19 pandemic era.

Birth Cohort and Racial/Ethnic Differences in the Age of First Oral and Anal Sex Among U.S. Men Who Have Sex with Men.

Earlier age of first sex has potential direct and indirect health effects later in life. Though there are multiple nationwide general population studies on ages of first sex, there is no such nationwide study of first male-male oral or anal sex among men who have sex with men (MSM). This may be important for understanding racial/ethnic disparities in HIV and sexually transmitted infection acquisition among young racial/ethnic minority MSM. Our study examined the birth cohort and racial/ethnic differences in ages of first male-male oral and anal sex using a diverse 2015 U.S. nationwide sample of 10,217 sexually active MSM. The mean age of first male-male oral sex was 18.0 years. Compared with older birth cohorts, those MSM born 1990-2000 were more likely to have younger age of first male-male oral sex. Compared to white MSM, Hispanic MSM and non-Hispanic black MSM were more likely to have younger age of first male-male oral sex with a man. The mean age of first male-male anal sex was 20.3 years. Compared with older birth cohorts, those MSM born 1990-2000 were more likely to have younger age of first male-male anal sex. Compared to white MSM, MSM of all other racial/ethnic groups were more likely to have younger age of first male-male anal sex. These findings emphasize the need for comprehensive and MSM-inclusive sexual health education for young teens and online sexual health resources for young gay, bisexual, queer, and other MSM.
