Willingness to use HIV pre-exposure prophylaxis has declined among Australian gay and bisexual men: Results from repeated national surveys, 2011-2013

Abstract

We surveyed willingness to use PrEP and the likelihood of decreased condom use among Australian gay and bisexual men in 2011 and 2013 (n=2384). Willingness to use PrEP declined from 28.2% to 23.3% (AOR=0.83, 95% CI=0.68-1.00, p=0.050). Willingness to use PrEP was greatest among men with HIV-positive partners and among those who had taken HIV post-exposure prophylaxis. Among men willing to use PrEP, the likelihood of decreased condom use remained stable between 2011 and 2013 (8.0% vs. 11.9%; AOR=1.40, 95% CI=0.80-2.45, p=0.23). A minority of men remain willing to use PrEP and appear to be appropriate candidates for it.
