title: HIV risk behaviour of older persons.
abstract: BACKGROUND
  This study investigated social and psychological determinants of preventive behaviour in HIV-relevant situations.
  
  
  METHODS
  Using computer-assisted telephone survey methodology, 2275 male and female were interviewed about their sexual habits.
  
  
  RESULTS
  For the first time in Switzerland, data concerning HIV-relevant protection as well as their determinants were systematically collected also from persons older than 45. This age group (n=834) showed an increased risk with regard to HIV-relevant sexual contacts.
  
  
  CONCLUSIONS
  The present findings call for more adequate monitoring of sexual behaviour of people older than 40 and suggest the development and implementation of respective age-specific prevention measures.
