Association between relationship characteristics and willingness to use PrEP among same-sex male couples: a cross-sectional actor-partner analysis in Guangzhou, China

Abstract

The association between relationship characteristics and pre-exposure prophylaxis (PrEP) acceptability among same-sex male couples has been limitedly examined. Dyadic survey data of 139 concordant HIV-negative same-sex male couples in Guangzhou, China were collected. The willingness to use PrEP was measured assuming that the participant’s partner was HIV-positive. The actor–partner interdependence model was used to examine how one’s relationship characteristics affected the PrEP willingness of the subject and his partner. Most participants (79.5%) were willing to use PrEP. The two individuals of the couple were distinguished by sex role in relationship, namely one usually playing the insertive role and the other usually playing the receptive role in anal intercourse. The former was labeled as “top” and the latter labeled as “bottom”. The PrEP willingness of the top partner increased when he would think his partner is having sex with other people if the partner requests condom use in relationship (AOR: 5.74, 95% CI: 1.10–29.87), and decreased when his partner would get violent upon condom use requests in relationship (AOR: 0.19, 95% CI: 0.04–0.88). The PrEP willingness of the bottom partner increased when he trusted his partner (AOR: 1.13, 95% CI: 1.02–1.25) and when he or his partner disclosed the relationship to parents (AOR: 10.57, 95% CI: 1.91–58.61). Considering the sex role and relationship characteristics in couple-based interventions are important to optimize PrEP uptake among HIV-discordant same-sex male couples.

Development of a relationship counselling website to identify and mitigate risk of intimate partner violence in the context of women’s PrEP use

“…Some of these features such as the audio content could make the site more accessible to those with poorer literacy or who lack the patience to read a lot of text. In addition, content catering to males seeking interventions for IPV exposure, to those in same-sex relationships, and to other geographic locations may be needed [ 50 – 54 ]. These adaptations could be accomplished using the existing website structure, which is available as open-source code and as embedded content on the South African Department of Health website, Home—B-Wise ( bwisehealth.com ) [ 55 ].…”

Willingness to use long-acting injectable PrEP among HIV-negative/unknown men who have sex with men in mainland China: A cross-sectional online survey

“…Each user can fill in the questionnaire only once according to the UID of each user. According to the sample size calculation formula of the cross-sectional study and the previous research in Guangzhou about the willingness of PrEP (79.5%), a sample size of 696 produced a two-sided 95% confidence interval with a width equal to 0.06[ 46 ]. Electronic informed consent was obtained from all participants through an online informed consent form before the questionnaire.…”
