Data based on free text
Occupational information from questionnaire 1 is coded for approximately 70 % of the participants. Occupational data is mainly available on an aggregate level. If more specific information is requested, a careful assessment of the overall data set must be performed to ensure the protection of participants’ identities and privacy.
All medicines stated in questionnaires during pregnancy and up until the child is 7 years have been coded using the ATC classification system.
Data based on free text are not part of MoBa standard data and must be specified in the application when applying for data.
