Questionnaires

DNBC participants - women and offspring - have contributed with their time and effort to establish a unique data source for research. In this section you will find information about DNBC questionnaires and data available.

Access to Data

More than 50 research groups from Denmark and abroad have gained access to DNBC data and more than 300 peer-reviewed publications and 18 PhD thesis have been published based on DNBC data.

If you have a research idea that requires prospectively collected data from pregnancy and early childhood, you are welcome to contact the DNBC secretariat for an application form for access to DNBC data.
