In a European sample men-who-have-sex-with-men (MSM), we aimed to identify factors associated with serostatus disclosure most recent anal intercourse (AI) partner. We also describe impact on exposure risks. During 2013 and 2014, 4901 participants were recruited for bio-behavioural Sialon-II study 13 cities. Behavioural data collected self-administered paper questionnaire. Biological specimens tested antibodies. Factors AI partner examined using bivariate multilevel multivariate logistic regression analysis. role Thirty-five percent (n = 1450) reported mutual their or disclosed having Most these disclosures occurred between steady partners (74%, n 1077). addition type diagnosis status, other positively model testing, no condom use, outness regarding sexual orientation.
