Korlesky et al. [36] analysed ferritin, hepcidin EPO, reticulocyte(RE)-ZnPP/H (erythrocyte zinc protoporphyrin/haem) and CRP in 201 cord bloods of newborns at greater risk of ID/IDA (such as maternal IDA, pre-gestational diabetes, gestational diabetes, small or large for gestational age infants, low socioeconomic status, ethnic minority) [113]. Here, EPO is linked to gestational diabetes.
