HIV risk behaviour of older persons.

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.
