title: The AIDS profile in a low risk country: the central role of bisexual men.
abstract: BACKGROUND
  Policies and measures for the prevention of human immunodeficiency virus Type 1 (HIV-1) transmission require adequate information about the risk profile of AIDS which is time-, place- and population-dependent. We have studied the risk factors for AIDS among men in Greece, a country with relatively low incidence of AIDS.
  
  
  METHODS
  A case-control study of all male patients with incident disease, who have been diagnosed in the major university-affiliated, AIDS Unit from February 1995 through August 1997 was conducted in Athens, Greece, a country with relatively low incidence of AIDS. Eighty-three AIDS patients were enrolled and an equal number of orthopaedic patients as controls. All interviews were conducted by the same physician and took place in the hospital.
  
  
  RESULTS
  There were no differences among heterosexual men with AIDS, homo- or bi-sexual men with AIDS, and controls with respect to any socio-economic variable. The odds ratio for AIDS among homo- or bi-sexual men, in comparison with heterosexual men, was 51.5 (95% confidence intervals 21.6-122.7). Blood transfusion, intravenous drug abuse and haemophilia were less important risk factors for AIDS in this study. Condom use was generally very low and there was a tendency for lesser use among men at highest risk for HIV transmission, that is, those with a preference for receptive anal intercourse.
  
  
  CONCLUSIONS
  AIDS among men in Greece is mainly driven by homosexual behaviour, but the relatively high proportion of bisexual men and the relatively low frequency of condom use are warning signs for the potential of the epidemic to expand in the future. The relatively low incidence of AIDS in Greece, in comparison with other European populations, may be due to a phase difference in the epidemic, but it could also be due to the traditional role separation of homosexuals in this geographical area, and the easy accessibility of disposable syringes and needles in Greece.
