Abstract

Background: Men who have sex with men (MSM) are at risk of HIV and are an important population to monitor and ameliorate combination prevention efforts. Aim: To estimate HIV prevalence and identify factors associated with frequent HIV testing (≥2 HIV tests in the last year) and pre-exposure prophylaxis (PrEP) use among MSM in London. Methods: For this cross-sectional study, MSM recruited from 22 social venues provided oral-fluid samples for anonymous HIV antibody (Ab) testing and completed a questionnaire. Factors associated with frequent HIV testing and PrEP use were identified through logistic regression. Results: Of 767 men recruited, 545 provided an eligible oral specimen. Among these, 38 MSM (7.0%) were anti-HIV positive including five (13.2%; 5/38) who reported their status as negative. Condomless anal sex within the previous 3months was reported by 60.1% (412/685) men. Frequent HIV testing was associated with, in the past year, a reported sexually transmitted infection (adjusted odds ratio (AOR):5.05;95% confidence interval (CI):2.66–9.58) or ≥2 casual condomless partners (AOR 2–4 partners:3.65(95%CI: 1.87–7.10); AOR 5–10 partners:3.34(95%CI: 1.32–8.49). Age≥35yearswas related to less frequent HIV testing (AOR 35–44years:0.34(95%CI:0.16–0.72); AOR ≥45years:0.29 (95%CI:0.12–0.69). PrEP use in the past year was reported by 6.2% (46/744) of MSM and associated with ≥2 casual condomless sex partners (AOR:2.86; 95%CI: 1.17–6.98) or chemsex (AOR:2.31; 95%CI: 1.09–4.91). Conclusion: This bio-behavioural study of MSM found high rates of behaviours associated with increased risk of HIV transmission. Combination prevention, including frequent HIV testing and use of PrEP, remains crucial in London.
