“…Since the introduction of widespread antiretroviral therapy (ART), evidence on the association between non-disclosure and condom use among HIV-diagnosed MSM has been mixed; certain studies found that nondisclosure was associated with higher prevalence of condomless sex or condomless sex with HIV-serodifferent partners (CLS-D) (Cook, Valera, & Wilson, 2015;Hirsch Allen et al, 2014;Klitzman et al, 2007;Morin et al, 2005;Parsons et al, 2005;Simon Rosser et al, 2008;Wilson et al, 2016), others found no evidence of an association (Kalichman, DiMarco, Austin, Luke, & DiFonzo, 2003;Marks & Crepaz, 2001;Poppen, Reisen, Zea, Bianchi, & Echeverry, 2005;Przybyla et al, 2014;Simoni & Pantalone, 2004;van Kesteren, Hospers, van Empelen, van Breukelen, & Kok, 2007), while some reported that non-disclosure was linked to condom-protected sex (Abler et al, 2015;Klitzman et al, 2007;Serovich et al, 2018;Simon Rosser et al, 2008). Studies that examined levels of disclosure to sexual partners showed that those who disclose to some partners tend to report higher levels of condomless sex compared to those who disclose to none or most/all partners (Abler et al, 2015;Brown, Serovich, Kimberly, & Umasabor-Bubu, 2015;Durham et al, 2013;Parsons et al, 2005;Simon Rosser et al, 2008). Only two studies from the UK (2008-09) (Elford, Ibrahim, Bukutu, & Anderson, 2008;Fox et al, 2009) showed prevalence estimates of disclosure to sexual partners, but none examined associations between disclosure and condomless sex.…”
