Assessment sequence, by participant and visit type. Oblong box indicates child and parent attended the station together. Parents attended the Young Bloods stations twice; first for their own blood collection, then to accompany their child. Food Stop included consumption experiment at the Main Assessment Centre (ie, data collected), but was simply offering refreshments at the Mini Assessment Centre (ie, no data collected). The NIH Vocabulary Picture Test was administered in Bone Zone at the Main Assessment Centre, and as part of Sit and Click in Mini Assessment Centre and home visits. In home visits, Sit and Click (child questionnaire) had allocated time between other assessments; for the Assessment Centre visits, Sit and Click did not have an allocated time or physical location (children completed the questionnaire in downtime at other stations). Postvisit activities (ie, accelerometry, child follow-up phone interview and non-attending parent buccal swab) are not included in the diagram and followed the same protocol regardless of visit type.
