[The National Child and Adolescent Health Survey. The complete concept]

The German National Health Interview and Examination Survey for Children and Adolescents aims at obtaining generalisable and practically convertible data and knowledge of the health situation of children and adolescents aged between 0 and 18 and living in Germany. After an extensive preparatory period of conceptional work by the Robert Koch Institute the beginning of this study is planned for spring 2003. Over a period of three years a representative sample of 18,000 young people will be medically examined and will be interviewed together with their parents. The investigational programme of the survey consists of a central part encompassing questionnaires and medical analyses of the most important health topics in childhood and adolescence. In addition, complementary modules will analyse subpopulations in-depth and extensively for specific aspects and questions. These modules are usually developed and financed by cooperating partners of the Robert Koch Institute. Soon after completion of the survey data first results will be made freely available to the scientific community in Public Use Files. These Files will become relevant sources for future health reporting addressing children and adolescents. Furthermore, they represent a reliable data base for epidemiological research and prevention programmes.
