ALSPAC: dietary data collection
ALSPAC collected dietary information from both mothers, their partners, and children at various time points (see the table below).
The information was collected using FFQs, diet diaries, and other diet-related questions.
The table below outlines the diet-related questions in ALSPAC:

Notes.
* Hyperlinks provided to the ALSPAC questionnaire in CLOSER Discovery or study website. Clinic visits and COVID19 questionnaires do not have a hyperlink; documentation for the clinic & COVID data is available through downloading the ALSPAC Data Dictionary.
▽ In the ALSPAC Data Dictionary, each questionnaire is stored in a single file and represented by a unique file code, which indicate the respondent. Typically these follow these rules (although there are some exceptions): single letter codes = mother/carer based; two-letter codes beginning with P or F = partner/father based; two letter codes beginning with K or T = cohort member-based but completed by the mother/carer; three-letter codes beginning with CC or YP = cohort member completed.
** asked of Children in Focus subsample (a 10% subsample of the main sample).
† Infant FFQ not detailed enough to estimate energy intake.
‡ One-day diet diary at age 4 months. Three-day diet diary for other ages.
Much of the diet questions and data are available in CLOSER Discovery. The ALSPAC study website also contains details of all the data that are available through a searchable data dictionary and variable search tool; links to relevant questionnaire sources in the table below. Details of the dietary collection methods have been discussed in a previous publication and will be briefly outlined here [94].
