According to universally acknowledged biopsychosocial model of development, numerous biological and environmental factors influence development of children. One of them is iron deficiency in the organism. The study assessed physical, motor and psychosocial development of children who at an early age had the diagnosis of iron deficiency anaemia and had been treated by iron drugs. Their neurological, receptive, expressive and cognitive functions were assessed using BINS (Bayeley’s Infanft’s Neurodevelopmental Screen). The sample was divided into 2 age groups: 16–20 and 21–24 months.

The study shows that in children, who had iron deficiency at an early age and had taken treatment with relevant drugs in a timely manner, the aggregate indicators of four clusters do not differ significantly from standard indicators submitted by BINS. We deem important time diagnosis of iron deficiency and beginning of respective treatment, in order to avoid problems in psychomotor development; Timely treatment will favour the processes of development of child’s social and school preparedness.
