Risk-taking sexual behaviour among adolescent can result in short-term and long-term consequences as early and unwanted pregnancy, abortion and sexually transmitted diseases (STDs). With the aim to promote responsible sexual behaviour it's necessary to be familiar with the rate of sexually active adolescents, their knowledge about contraception and STDs and their attitude towards their own sexual activity. The research was conducted on the representative sample of 1723 secondary-school students in Ljubljana, attending first and third class. The data were collected by the questionnaire having 25 questions about sexual behaviour, knowledge about contraception and STDs, the sources of information and attitudes towards sexuality and its unwanted consequences. The research was conducted in February 1994.
