Objective: We investigated factors associated with unprotected sex in regular partnershipsamong homosexual men living with HIV.Method: We used data from a French national representative sample of people livingwith HIV (ANRS-EN12-VESPA survey). This analysis included men in a regular partnershipwith another man for at least twelve months. Unprotected sex was defined asreporting at least one episode of sexual intercourse without a condom with this regularpartner in the previous 12 months. Separate analyses were conducted in sero-nonconcordantcouples and in HIV-positive seroconcordant couples.Results: 285 and 193 homosexual men respectively reported a regular sero-nonconcordantand seroconcordant partner. Unprotected sex was reported by a higher numberof respondents within seroconcordant (46.7%) than within sero-nonconcordant couples(15.6%).In both seroconcordant and sero-nonconcordant partnerships, unprotected sex wassignificantly more frequent when episodes of unprotected sex with casual partners werereported. In seroconcordant couples, those who had more than four casual partnerswere also more likely to practise unprotected sex with their regular partner. Amongsero-nonconcordant couples, binge drinking and absence of disclosure of one’s HIVpositivestatus to the partner were also independently associated with unprotected sex.Conclusions: A limited number of sero-nonconcordant homosexual couples persist inreporting risky sexual behaviour. Prevention messages should encourage communicationand HIV disclosure. The relationship between unprotected sex with both casualand regular partners also calls attention about the underlying psycho-social andinteractional factors that may influence sexual behaviours of people living with HIVin regular relationships, independently of the status of the partner.
