RESUMO
BACKGROUND: Sexual activity is often initiated during the adolescent period, and previous research suggests that the age of first sexual intercourse and condom use are crucial determinants of later sexual health. This study examined trends in adolescent sexual behaviours from 2002 to 2010 in 20 countries across four geographical regions of Europe. METHODS: Data were collected by self-report questionnaires from 15-year-olds in classrooms during 2002, 2006 and 2010. Linear time trends were determined through logistic regression models, stratified for gender. RESULTS: No linear trend over time was documented for most countries for sexual intercourse at the age of 13 or younger. Increased initiation among girls in Eastern Europe and decreased very early initiation among girls in Northern Europe emerged, along with a general increase in condom use in boys and most notably in girls. CONCLUSION: Overall prevalence of early and very early sexual intercourse initiation was quite stable in Europe between 2002 and 2010, while condom use increased. More detailed research and policy attention to the antecedents of non-condom use among young people is warranted; and further study of the relationships between age of sexual initiation and condom or pill use would be particularly valuable.
