Negotiated safety and other agreements between men in relationships: risk practice redefined.

This study examines patterns of agreement, knowledge and practice which can prevent or facilitate HIV transmission among men who are in regular ('primary') male-to-male relationships. Data are from a national volunteer phone-in survey of homosexually-active men in Australia. A sub-sample of 1070 men from a larger sample (n=3039) were found to have one or more regular partners for longer than 6 months. Self-reported HIV serostatus of survey participant and his regular partner, type of agreement regarding anal intercourse both within and outside the regular relationship, and engaging in unprotected anal intercourse with regular and with casual partners were examined. Risk practice was defined as unprotected anal intercourse with a regular partner of different or unknown serostatus and/or unprotected anal intercourse with a casual partner. Agreements were classified as: negotiated safety (28.8%); no unprotected anal intercourse (33.6%); unsafe (10.6%) and no agreement (17.0%). Risk practice was reported by 17.8% of the men. Type of agreement was found to be the strongest predictor of risk practice. Negotiated safety agreements were common, and were kept on the whole. Men with unsafe agreements, although only a small proportion of men in relationships, had high levels of risk practice.
