Checklist for papers

All MoBa articles must go through an administrative approval from the MoBa management group to ensure that the analyses are performed according to the approved application and that MoBa is described correctly. Here is the checklist that should be sent in with the article.

Request for syntax files

We ask that syntax files that define the study population and the main variables are sent to MoBa. Please include a short verbal description for each main variable. Syntax files are sent to datatilgang@fhi.no. The files will be used only for the purpose of reproducing results, or for commenting on those results in a letter to the editor if needed.

Abstract: This study is based on the Norwegian Mother and Child Cohort Study (MoBa).

Material and Methods: The Norwegian Mother and Child Cohort Study (MoBa) is a prospective population-based pregnancy cohort study conducted by the Norwegian Institute of Public Health.

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 in (to be filled in).

If blood samples were used in the current study: Blood samples were obtained from both parents during pregnancy and from mothers and children (umbilical cord) at birth. 

Approvals: The establishment and data collection in MoBa was previously based on a licence 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 (references).

Consortia manuscripts where MoBa contributes with metadata

If it is not possible to include the description of MoBa in the main manuscript, we ask that a minimum description of MoBa with main references should be included in the supplement. Authors contributing to consortia manuscripts with MoBa data must send us a copy of the published paper, to be included in our publication list.

Open data practice – Not applicable to MoBa data

Due to the MoBa consent, researchers cannot make data files available in connection with publication. However, researchers can provide information on where to apply for data sets. This is a suggested standard text to journals that want access to the research data:

Data Availability: The consents and approvals for MoBa do not allow storage of data in repositories. However, it is possible to apply for access to data-sets for replication from datatilgang@fhi.no. Ethical approval and relevant agreements will be required.
