This study determined whether YBMSM endorsing serosorting are less likely to use condoms. A questionnaire assessed men's attitudes towards serosorting with a three-item scale; various sexual risk behaviours were measured using a 90-day recall period. Favourable attitudes toward serosorting were associated with a greater likelihood of condomless sex as a top (P<0.001) and as a bottom (P<0.001), as well as a lower likelihood of using condoms with main partners (P≤0.003). Findings suggest that YBMSM having favourable attitudes toward serosorting may be more likely to report condomless sex than their counterparts without favourable attitudes.
