The aim of this paper is to establish the effect of iron therapy on mental and motor development in children suffering from iron deficiency anaemia by Bayley Scales of Infant Development (BSID).
Patients and methods: In prospective study were enroled 90 anemic children with Hb < 110 g/l and 30 healthy children with Hb > 110 g/l, all of them 6-24 months of age.
Results: Indexes of mental development (MDI) before and 3 months after iron therapy for group of patients with severe and mild form of anemia (Hb < 95) did not show statisticaly significant difference (p > 0.05) before and after three months after iron therapy. Before iron therapy there was statisticaly significant difference (p < 0.001) between group with Hb < 95 g/l and group with Hb 95-110 g/l, and also statisticaly significant difference (p < 0.001) between anemic groups and control group. Indexes of psychomotor development (PDI) before and three months after iron therapy were similar to results MDI.
Conclusion: level of Hb < or = 95 g/l had great importance for results BSID test in infants and small chilren up to age of two years.
