Abstract
This report describes some of the findings of a survey of British 16–19-year-olds in tertiary education [N = 3665], focusing on their knowledge of HIV risk behaviours. The analysis is presented by gender and overall response rates. The aim is to provide evidence to health educators on the effectiveness of existing information campaigns. Therefore particular emphasis has been given to the areas where respondents were 'not sure' or were incorrect about the risks of an activity. The survey method was a self-report questionnaire which covered a range of topics, including knowledge about HIV risk behaviours. Most young adults are relatively well informed about the risks associated with unprotected sexual activity, but that a relatively high proportion seemed to be uncertain about other activities which may risk HIV transmission. Furthermore, approximately one third of respondents were 'unsure' about some myths concerning HIV vectors, e.g. infection via lavatory seats and skin contact with others.
