4. Standard text for use in “Abstract” and “Material and Methods”


The following text should be used in all manuscripts: "This study is based on the Norwegian Mother and Child Cohort Study (MoBa)."

Material and Methods

The following text should be used in all manuscripts

"The Norwegian Mother and Child Cohort Study (MoBa) is a population-based pregnancy cohort study conducted by the Norwegian Institute of Public Health. Participants were recruited from all over Norway from 1999-2008. The women consented to participation in 41% of the pregnancies. The cohort now includes 114.500 children, 95.200 mothers and 75.200 fathers. The current study is based on version (to be filled in) of the quality-assured data files released for research on (to be filled in)."

If data from MBRN is used the following text should be included: 

"The Medical Birth Registry (MBRN) is a national health registry containing information about all births in Norway."

If blood samples were used in the current study the following text should be used:

"Blood samples were obtained from both parents during pregnancy and from mothers and children (umbilical cord) at birth."

The following text regarding approvals should be used in all manuscripts:

"The establishment and data collection in MoBa was previously based on a license from the Norwegian Data protection agency and approval from The Regional Committee for Medical Research Ethics and it is now based on regulations related to the Norwegian Health Registry Act. The current study was approved by The Regional Committee for Medical Research Ethics (to be filled in)."

6. Keywords

To ensure that the MoBa cohort is identified consistently in scientific papers based on data and biological material from MoBa, we prefer that authors use the acronym MoBa and The Norwegian Mother and Child Cohort Study as keywords.

7. The syntax file used in the manuscript

The manuscript must be accompanied by a syntax file showing how the study population was selected and how the main variables were defined. The syntax will only be used to reproduce the results or to comment on them in a letter to the editor of the journal in which the manuscript is published. The syntax must be sent to MorBarnData@fhi.no including project title, MoBa reference number as well as the manuscript title. Stored syntax files will be treated confidentially, and cannot be distributed to others without a written permit from the Principal investigator (PI). 

8. Confounding effects

MoBa has a restrictive policy when it comes to publishing the direct effects of confounding variables, in order to avoid infringement on other sub-studies. Such information should not be published, but can be submitted to referees/editors if required.

9. The final paper

Once your paper is accepted for publication, please send a copy of the manuscript in PDF format to mobaadm@fhi.no.

10. Media coverage 

We encourage media coverage of MoBa papers where this is appropriate to increase knowledge of the study as well as to show the participating families and other relevant target groups that the study generates valuable results. All contact with the journalists should be based on results accepted for publication in scientific journals, or as printed abstracts at scientific conferences, and it should be made clear that the results are from The Norwegian Mother and Child Cohort Study. If you would like assistance with media relations, please contact the MoBa communication officer. Please send a copy of the press release or media coverage to mobaadm@fhi.no. Press releases can be made public on the NIPH website as well as in the publication list of MoBa papers.

11. Brief popular science summary of the accepted article

We will ask you to make a brief popular summary of the paper to be used for communication and dissemination purposes and send it to mobaadm@fhi.no, if required.

12. Consortia manuscripts where MoBa contributes with metadata.

If it is not applicable to include description and reference to MoBa in the manuscript, a minimum description of MoBa with main references must be included in the supplementary part. Researchers contributing to consortia manuscripts with MoBa data must send us a copy of the published paper, to be included in our publication list.

13. Open data practice 

Researchers cannot make MoBa data available at an individual level to others in connection with publishing regarding to Norwegian legislation. Suggested standard text for journals wishing to access the research file: 

"The consent given by the participants does not open for storage of data in repositories or journals.  If other scientists want to have access to relevant data sets for replication, an application to datatilgang@fhi.no should be made. This will require approval from an ethics committee and a formal contract with MoBa."

If a journal requires summarised data in publications based on genomic data (MoBa Genetics) to be made available, please contact mobaadm@fhi.no as early as possible.
