Abstract:

Introduction Minerals and trace elements such as zinc and copper have significant influence on development and growth of the fetus and newborn. The purpose of this study was to determine the relationship between low birth weight and maternal and neonatal zinc, copper levels. Materials and Methods This case – control study   was done from September 2006 to Sep 2007 consisted of 65 infants with birth weight < 2500 g and 65 infants weighing ≥ 2500g.  Cord and maternal blood samples collected at delivery were analyzed by atomic absorption spectrophotometry for zinc and copper levels.  Results Mean serum zinc levels in maternal (P=0.001) and the cord blood (P=0.49) were 6.35 ± 2.09 µmol/l, 12.77±3.83 mol/l and 7.57±1.75 µmol/l , 13.18±2.69 µmol/l of cases  and control groups ,respectively.The mean copper levels in maternal (P=0.62) and cord blood (P=0.005) were 21.82±4.45 µmol/l, 5.12±1.54 µmol/l and  21.19 ± 5.34 µmol/l and  3.65±2.04 µmol /l of control and case group, respectively. Conclusion This study indicated that there is a relationship between birth weight less than 2500 gr and maternal zinc levels (P

The Relationship between Cord Blood and Maternal Serum Zinc Levels and Birth Weight

Background: Examining the relationship between cord blood and maternal serum zinc levels and birth weight.Methods: A total of 127 infant-mother pairs were assigned to study (n = 58; with birth weight < 2500 g) and control (n = 69; with birth weight ≥ 2500 g) groups. Serum samples were collected from eligible mothers and cord blood of their low birth weight (LBW) or normal birth weight (NBW) hea...

Patterns of Maternal Weight Gain During Pregnancy and Birth Weight

Anthropometric parameters are an important indicator of health and nutritional status comprising the whole span of mans life. However, they are not of the same degree of simplicity and sensitivity in assessing the public health status. During recent decades many studies have attempted to examine the relationships of these measurements in order to present simple alternatives for similar purposes...

maternal and neonatal serum copper level at birth

total serum copper levels of 70 pregnant women hospitalized for delivery at misaghieh (private), 90 at farah (public) maternity hospitals immediately after delivery and 27 non-pregnant women (control) were measured. the copper level in the blood serum of umbilical cord of the newborn infants was also determined. the copper levels were significantly elevated in both pregnant groups as compared t...
