Dietary information in selected CLOSER studies
Each of the original eight longitudinal population studies in CLOSER have some information on dietary intake (as documented in the table below).
ALSPAC and SWS are highly focused on diet and include both FFQs and diet diaries. HCS, also focused on diet, has collected dietary information primarily using FFQs. NSHD and BCS70 have collected dietary intake using diet diaries while NCDS has used recall.
MCS and UKHLS have not used a traditional DAT (i.e. FFQ, diary or recall) but do include other diet-related questions.
