Access to DNBC data
The DNBC participants - women and adolescents - have contributed with their time and effort in order to establish a unique data source for research. Read more about the conditions for access to DNBC data and the applications process below.
Conditions for access to data
The Danish National Birth Cohort operates an open access policy. The DNBC Steering Committee will, however, give priority to projects already launched and agreements made.
Access to electronic data from interviews, data linkage and ad hoc analyses.
Access to personalised data requires permission from the both the Danish Data Protection Agency as well as from the DNBC Steering Committee.
- The Steering Committee will not grant access to projects that may harm the DNBC’s reputation nor to projects whose purposes are incompatible with the overall aim of the project.
- The DNBC management takes no responsibility for the scientific quality of projects in which they have no part.
Access to biological specimens
The access policy for biological specimens will be restrictive. The Scientific Ethical Committee, the Danish Data Protection Agency and the DNBC Management must sanction any access. The Steering Committee will ensure the following:
- a minimum only of biological material should be used
- data must be analyzed in certified laboratories. Any remaining material should be restored to the biological bank
- a considerable quantity of the biological material should still be available in the bank when the cohort children reach the age of 18.
- biological specimens should be given solely to projects, which require blood samples or other information to be collected during pregnancy (gene-environment interaction).
- a study design must be chosen which best utilizes the biological specimens.
- the applicants should account for the feasibility of the analyses (requirements for transportation, fractioning and storage of the blood must be taken into account
- biological material may be used for purposes that do not comply with the NBC overall aim. Thus, biological material will not be given to commercial purpose projects, nor for use in analyses where results will not be published.
- in cases of important terapeutical action only may biological material be handed over to individuals for diagnostic purposes
The DNBC Steering Committee may revise the present guidelines at any time.
Data from the Danish National Birth Cohort are public domain data with some restrictions. The cohort is mainly financed by means of Danish national sources. It is therefore our hope that epidemiologists from outside the country who wish to use data from the DNBC will do so in collaboration with Danish scientists, preferably by carrying out the data analyses in Denmark.
Request the DNBC Application Form
Please start by requesting the newest version of the DNBC application form.
Send your request to: firstname.lastname@example.org
Fill in the form and return it together with a short protocol to: email@example.com.
Your application will be given a reference number and will be submitted to the DNBC Management and then to the DNBC Steering Committee. You can expect to hear from us again after 6-8 weeks.
If you are asking for data where individuals may be identified, you must be approved by the Danish Data Protection Agency (Datatilsynet).
If you are applying for biological material you also need permission from the Committee on Biomedical Research Ethics (Videnskabsetisk komité).
Application and data fees
From October 1st, 2018 the DNBC introduces a new fee policy for the processing of applications and data access. This means that you should allow for the following fees when drafting your project budget:
- Administration fee (processing of application) to DNBC secretariat: DKK 4.000,-
- Access to data for projects that include 1 planned scientific publication: DKK 21.000,-
- Access to data for projects that include up to 4 planned scientific publications: DKK 41.000,-
- Working with data on our VDI server (annual fee): DKK 5.000,-
The price for your data set will depend on the time our data managers spend on assisting you and constructing your data set. Usually, the price will be around DKK 10 - 15,000.
Price example: total price for a project including a maximum of four publications: 4.000 + 41.000 + 10 - 15,000 = DKK 55 - 60,000
In addition there is an annual fee of DKK 5,000 if you choose to work on our VDI server (if you access your data from Statistics Denmark this fee will lapse).
Fees for biological samples
Samples retrieved from manual storage - (price per sample, ex VAT):
- less than 500 samples DKK 30,-
- more than 500 samples DKK 25,-
Samples retrieved from automated storage:
DKK 10,- per sample
Automated sample aliquotation:
- less than 500 samples DKK 65,-
- more than 500 samples DKK 60,-
DNA extraction, 200µl concentration measurement, normalisation:
DKK 95,- per sample
Other services (per hour):
- Laboratory 832,-,
- IT 1.389,-
Your data set will be available on our server
To enhance data security your data set will be made available to you through a secure connection to our server at Aarhus University. We can also send the data set to Statistics Denmark. Please direct your inquiries to data managers Lone Fredslund or Inge Eisensee at firstname.lastname@example.org.
If you already know that you will be working with data on the Aarhus University server (VDI), please read the below document carefully before filling it out and returning it to Lone Fredslund at email@example.com.
