In this article, we present data from a recent online cross-sectional survey with gay, bisexual and other men who have sex with men (GBMSM) in the United States to illustrate changes in IPV risks that have occurred during the U.

Partnered gay, bisexual and other men who have sex with men (GBMSM) are less likely to engage in HIV and STI testing. We enrolled 51 male couples from a larger study of home HIV testing to test the feasibility of a dyadic home STI testing intervention delivered via telehealth, consisting of two telehealth sessions delivered via video-chat.

Transgender youth have low rates of engagement in HIV prevention, shaped in part by experiences of transphobia and lack of access to culturally competent care. Project Moxie tested the feasibility of an intervention that provides home-based HIV self-testing coupled with video-chat counseling. A diverse sample of 202 binary and nonbinary transgender youth (TY) were recruited online, and randomized 2:1 to receive the intervention or a control condition of only home-based HIV self-testing.

Background: HIV prevalence remains high among men who have sex with men (MSM) in the United States, yet the majority of research has focused on MSM as individuals, not as dyads, and has discussed HIV risks primarily in the context of casual sex.

It allows partners in dyadic MSM relationships to receive HIV testing and care in the comfort of their designated residence, via video-based chat.
