The Adolescence Medical Group in Sweden has performed a questionnaire every second year since 1990. The questionnaire is performed during school hours in seventh and ninth grade and also in the second grade in the upper secondary school (gymnasium). The questionnaire is completed anonymously. The schools are not chosen by statistical methods, but more depending on youth-health-iterested school doctors and nurses who have interest in these studies. The result of these studies has been used locally in each community, but also been reported for example i Acta Pediatrica. After the war in Bosnia there has been different projects to help to build up the countries health system, for example in psychiatry. The question was laso raised how the youth health was in Bosnia. Representatives from the Adolescence section in Sweden were invited to Bosnia to introduce the questionnaire and also to help in analysing the results. We were also in Bosnia to present results to local authorities and those who performed the study locally.
