 AB    INTRODUCTION: In Australia, exposure to HIV for the majority of cases of
       newly diagnosed HIV infection has been attributed to male homosexual
       contact (85%). In this study homosexually active men who had recently
       seroconverted were compared with men who had not seroconverted in order
       to investigate the social and behavioural determinants of HIV
       seroconversion. METHODS: Men from Sydney and Melbourne with newly
       acquired HIV infection, identified by a diagnosis of HIV seroconversion
       illness or a negative HIV antibody test within one year of diagnosis,
       occurring during the interval 1 January 1993-30 June 1994, were reported
       to the study co-ordinators through a network of general practitioners,
       HIV diagnostic laboratories and via the longitudinal cohort study
       (SMASH). Controls were obtained in two main ways: homosexually active
       men who attended the same medical practice at a time close to when the
       case attended were recruited; and homosexually active men from the SMASH
       cohort. Both cases and controls were interviewed with respect to
       demographic characteristics including educational level, occupation,
       age, identification with and attachment to gay community, and sexual and
       drug use history. RESULTS: By June 1994, 27 cases and 9 controls in
       Sydney and 17 cases and 12 controls in Melbourne had been interviewed.
       72 controls from the SMASH cohort study have also been interviewed. Of
       the 44 cases, 63% in Sydney and 41% in Melbourne reported unprotected
       receptive anal intercourse as the perceived cause of HIV infection,
       while over 80% of the men in both cities reported no condom use on the
       occasion of perceived transmission, whatever the sexual activity. In
       Sydney approximately equal proportions of cases attributed the source of
       HIV infection to sex with their regular partner and to sex with a casual
       partner; in Melbourne the majority of transmissions were attributed to a
       casual sexual partner (82%). Two analyses, using the two different
       controls, identify a number of demographic and social characteristics
       which are associated with seroconversion.
