Health in Men (HIM) Study

Health in Men (HIM) is a long-term study of an open cohort of HIV-negative gay men in Sydney. The study was funded initially (2001–2002) by the Commonwealth Department of Health and Ageing and the New South Wales Health Department. From mid-2002 funding was provided by the US National Institutes of Health, a division of the Department of Health and Human Services, as part of the Australian Thai HIV Vaccine Consortium (NIH/NIAID/DAIDS:HVDDT Award N01-AI-05395).

Key findings
  • The 2002 recruitment was largely drawn through gay community events and gay venues. This differed from the 2001 recruitment, which had a sizeable proportion from the previous SMASH study.
  • For both 2001 and 2002, half of the sample changed their relationship with men between interviews. In both years, about a third of these men were in a regular relationship with the majority in a non-monogamous relationship.
  • For both 2001 and 2002, there were no significant changes in the total numbers of male partners, regular male partners, and casual male partners in the six months prior to interviews.
  • In both years, about a quarter of the sample reported more than ten male partners in total. On the other hand, a third reported one regular partner and one-in-six no regular partners. In terms of casual male partners, about a quarter reported more than ten partners, while one-in-eight had no casual sex during 2001 and 2002.
  • For both 2001 and 2002, a third  reported having an HIV-negative primary partner at both interviews.
