One hundred and seventy-six men who had engaged in sexual activity with other men in the past six months were interviewed, in the western area of Sydney, about their sexual activities and knowledge as related to the acquired immunodeficiency syndrome (AIDS). Comparisons were made between men who had frequented "beats" (public toilets, parks or isolated roads where men meet for homosexual encounters) in the past six months, and those who did not use beats. One-quarter of those men who frequented beats reported beats as their only venue for meeting men for sexual contact, while other men reported them as one of many venues that they used to meet men. Although all interviewed men were engaging in sexual activities with men, 12 men described themselves as heterosexual, and 12% of those men who used beats, and 7% of the beat non-users, were married or in de-facto relationships. In comparing those who used beats with the beat non-users, 64% of beat users had engaged in sexual practices with between six and 50 different partners in the past six months compared with 8% of beat non-users. Beat users also were more likely to engage in unprotected anal intercourse with causal partners. Nineteen men claimed to be HIV-seropositive for the human immunodeficiency virus, with 11 of these men still engaging in high-risk sexual activities. The implications for AIDS education are discussed.
