By what ID can I get the record time or participant age that 41267（Number of previous pregnancies） corresponds to. It includes 6 arrays. The date or age of the participant corresponding to each Array.

Also, I can't confirm who the age of the 41286  ( Mother age on date of delivery ) variable says it refers to (the participant himself/herself or the participant's mother). If it is the age of the participant, can this age correspond to the age of 41267 above?

    Hi Alex,

    Thanks for posting your query on the UK Biobank Community Forum. 

    To extract the hospital episode dates for each of the arrays relating to data-fields 41267 and 41286 (which are summary fields), you will need to query the ‘hesin’ and ‘hesin_maternity’ tables of the record-level hospital inpatient admissions data (see Resource 138483 for details: https://biobank.ndph.ox.ac.uk/showcase/refer.cgi?id=138483). The hesin table includes the episode dates for each admission, and can be linked to the hesin_maternity table using the columns ‘eid’ and ‘ins_index’. The hesin_maternity table includes the columns ‘numpreg’ (data-field 41267) and ‘matage’ (data-field 41286). The latter relates to the participant’s age at delivery.

    Best wishes,

    Catherine
