title: Age at first intercourse in an Australian national sample of technical college students.
abstract: OBJECTIVE
  This study aims to broaden the current body of knowledge regarding the sexual behaviour of young Australians by examining the age and correlates of age of first intercourse in a national sample of Technical and Further Education apprentices.
  
  
  METHODS
  In 1995, students at randomly selected technical colleges in Australia were surveyed on HIV-related issues. Questionnaires were administered to a stratified cluster sample of automotive, hairdressing and commercial cookery apprentices. Respondents were asked the age at which they first had heterosexual vaginal or anal intercourse.
  
  
  RESULTS
  Of 4,055 respondents aged 15-24 years, 3,848 answered the question; 3,195 (83%) had had intercourse. Males and females did not differ significantly. Median age at first intercourse was 16 (range 12-23). In multivariate analysis, older age at first intercourse was associated with: greater age at interview; higher school education; church attendance; and State of residence. The model, however, accounted for only 14% of the variance in age at first intercourse.
  
  
  CONCLUSIONS
  In this sample, those apprentices who completed secondary school became sexually active later on average than those who left before the end of Year 10. For sex education to occur before sexual initiation, it needs to be offered in primary schools and the first year of high school (aged 11-13 years). Further, as technical college students are likely to initiate sex earlier than their age mates still at school, colleges may be in a position to take responsibility for the continuing sexual education of this group, especially for those students entering college at 15 or 16 years of age.
