Introduction. The aim of this work was to evaluate the growth velocity and neuroconductal development of non-anemic iron deficient infants. Material and methods. Infants aged 6 to 8 months were stratified in 2 groups: in group 1 infants (n =22) with serum ferritin (SF) < 20 ug/L were included in group 2 infants (n =29) with normal iron store (SF > 20 µg/L) were studied. Growth velocity, motor area (PDI) and mental area (MDI) using the Bayley Scale (BS) were evaluated. Results. The proportion of cases with abnormal PDI score was greater in group 1 (0.41 vs 0.07); the global MDI score was 86 vs 99, and the proportion of abnormal values were also greater in group 1 (0.54 vs 0.07) group 1 had a greater risk to exhibit a lower BS score (OR 13.5). In addition, infants with SF < 12 µg/L presented lower values of PDI and MDI scores (OR =13.5) and a higher risk for low, BS score (OR =83.5) was associated with greater growth velocity in weight and weight gain with respect to birth. Conclusions. Iron deficiency, even in non-anemic infants, may be associated to a significant score decrease in neurodevelopment scales, particularly in the mental area. The accelerated body growth observed is and independent variable that increases iron consumption in infants.
