Objectives: Zinc and Iron are essential micronutrients in fetusgrowth and development. The aim of this study was to assess therelationship of maternal serum Zinc, Hemoglobin and Ferritinlevels with their newborns weight, height and head circumference. Methods: This cross sectional-analytical study carried out amongpregnant women referred to Naghavi Polyclinic, Kashan, Iranfrom November 2009 to October 2010. One hundred and twentyninepregnant women in the third trimester were selected andanthropometric factors of their newborns (weight, height and headcircumference) and their relation to serum Zn, Hemoglobin andFerritin concentrations were assessed. Results: Serum Hemoglobin deficiency (<11g/dl), serum Ferritindeficiency (<12 µg/L) and serum Zn deficiency (<66 µg/dl) werepresent in 11 (8.5%), 9 (7%) and 9 (7%) women, respectively.The proportion of newborns with birth weight of 2500-2999 gwas greater among mothers with lower Hemoglobin (<11 g/dl)compared to mothers with normal Hemoglobin (≥11 g/dl; p=0.04).Multiple regression analysis showed that among biochemicalcharacteristics of pregnant women, serum Hemoglobin levels werepositively correlated with low birth weight (β=0.26; p=0.04). Butserum Zn and Ferritin levels were not significantly associated withweight, height and head circumference. Conclusion: Low maternal serum hemoglobin levels are associatedwith low birth weight and does not have any association withbirth height or head circumference; but there was no significantassociation between maternal serum zinc and Ferritin levels withweight, height and head circumference.
