[Prevention of unwanted pregnancies in adolescents in a suburb--is it valuable?].

By counting cases of induced abortion among girls aged 15-19 years from 1988 to 1990 in Stovner district, Oslo, we evaluated a programme to prevent unwanted pregnancies among young women. The programme consists of several approaches, including free health services for teenagers at a special youth clinic, more education, at school and at youth clubs etc, in the use of contraceptives, and alcohol-free weekend arrangements. From 1988 to 1990 the number of abortions decreased from 35/1000 to 15/1000. Although this difference is significant (p < 0.01), one must be careful in drawing conclusions, owing to the small size of the sample.
