  1. NOTES: 1 Where data items can be collected in either community-based family assessments or school-based measurements we mostly collect data at one time, to provide flexibility and optimise recruitment (some repeat measurements are collected for use in quality control and reliability assessments). 2 Excluding women who are pregnant. 3 Offered as an option if participant does not want a blood sample to be taken. 4 For subsample of children in sub-study on renal function only. 5 For subsample only
