title: HIV risk behaviour and HIV testing of psychiatric patients in Melbourne.
abstract: OBJECTIVE
  Patients with chronic mental illnesses constitute an important risk group for HIV infection overseas. This study aimed to determine the prevalence of risk behaviours associated with HIV transmission and factors associated with HIV testing in psychiatric patients in Melbourne.
  
  
  METHODS
  Inpatients and outpatients completed an interviewer-administered questionnaire which covered demographics, psychiatric diagnosis, risk behaviour, and HIV education and testing.
  
  
  RESULTS
  Of 145 participants, 60% were male and 55.2% had schizophrenia. Injecting drug use (IDU) was reported by 15.9%, a figure approximately 10 times that found in other population surveys. Most patients reported sex in the last decade and over 20% had multiple sexual partners in the last year. Of males, 12.6% reported sex with another male (9.2% anal sex); 19.0% of females reported sex with a bisexual male. Nearly half of the males reported sex with a prostitute, 2.5 times that in a population sample. Only 15.9% reported ever having someone talk to them specifically about HIV and its transmission, although one-third had been tested for HIV. In multivariate analysis, male-male sex, paying for sex, and IDU were associated with HIV testing, but those whose primary language was not English were less likely to be tested. Those who had received HIV education were more likely to have used a condom last time they had sex (OR 4.52, 95%CI 1.49-14.0).
  
  
  CONCLUSIONS
  This study provides evidence that those with serious mental illness in Victoria have higher rates of participation in risk behaviour for HIV infection than those in the general community. Attention to HIV education and prevention in this group has been inappropriately scant; strategies to encourage safer behaviour are urgently needed.
