Iron/anaemia markers not measured at birth.
Anaemic defined as haemoglobin <11g/dL.
Iron deficient defined as ferritin <12μg/L if CRP < 5mg/L or ferritin <30μg/L if CRP≥ 5mg/L, IS; iron sufficient defined as ferritin ≥12μg/L if c reactive protein (CRP) < 5mg/L or ferritin ≥ 30μg/L if CRP ≥ 5mg/L.
IDA; iron deficiency anaemia defined as concurrently iron deficient (as ferritin <12μg/L if CRP < 5mg/L or ferritin <30μg/L if CRP≥ 5mg/L, IS; iron sufficient defined as ferritin ≥12μg/L if c reactive protein (CRP) < 5mg/L or ferritin ≥ 30μg/L if CRP ≥ 5mg/L) and anaemic (haemoglobin <11g/dL).
