^*Haemoglobin in grams per decilitre;

^**“Mild” is a misnomer: iron deficiency is already advanced by the time anaemia is detected. The deficiency has consequences even when no anaemia is clinically apparent (WHO/NMH/NHD/MNM/11.1; http://www.who.int/vmnis/indicators/haemoglobin.pdf, accessed on 20/12/2014).
