“…This phenomenon is thought to be related to ph ysiological or hormonal factors rather than nutritional effects ( 13). The significantly higher cord blood zin c level in preterm infant s roughly coincides with the earlier findings (14,15) and supports the ob servation that serum zinc lev els in cord blood were negati vely correlated to gestation ( 16). It was rep ort ed by Henkin et al (17) and Bassiouni et al ( 18) that the cord blood zi nc level was higher than the mat ernal zinc level on normal deli very .…”

SummarySerum zinc levels were monitored serially in pregnant women. Compared with those of age‐matched nonpregnant women, their serum zinc levels were significantly decreased in the first trimester (p < 0.005) and further decreased in the second trimester (p < 0.005) but then remained unchanged until delivery. Cord blood zinc levels and the ratio of cord blood to maternal serum zinc at delivery were significantly higher in preterm than term (≥ 37 weeks) infants (p < 0.05, p < 0.05). The maternal serum zinc level in the second trimester was not related to the birth weights of the infants. Mothers with serum zinc levels of <65 μg/dl in the last trimester showed a higher incidence of birth weights of less than the 50th percentile (p < 0.005) and also of less than the 25th percentile (p < 0.005) on term delivery. The incidences of birth weights of less than the 10th percentile on term delivery were similar for mothers with serum zinc levels of ≥65 μg/dl. This observation suggested that a relatively lower birth weight may be associated with lower maternal serum zinc levels in the third trimester, but an additional factor (factors) is also involved in the outcome of low birth weight infants.

The concentrations of the essential trace elements Cu, Fe, and Zn, and of the mineral elements Ca, K, Mg, and P during the perinatal period in human placenta and in the blood of the mother and the newborn (cord blood) were determined. Breast milk (colostrum and transitory milk) was also included to permit correlations between the different compartments. No correlations were found. The uptake by nutrition and the body-pools of the mother and their mobilization for these elements seem to be sufficiently high for an adequate supply of the fetus and the milk in the geographical region of Munich (Bavaria, FRG) under these investigations. Differences in the mineral-and trace element concentrations of colostrum and transitory milk for the elements P and Zn and to a lesser extent for Ca and Mg were observed. Additionally, breast milk samples from different geographical regions in Bavaria were investigated. Results for the heavy metals Cd, Hg, and Pb, and for the essential trace element Se are also presented for these samples, and can be seen as a reflection of the overall environmental and dietary influences during pregnancy in these geographical regions. ICP (Inductively Coupled Plasma)-emission spectrometry was used for the determination of the elements Cu, Fe, Zn, Ca, K, Mg, and P. For the additionally given elements in the milk-samples anodic stripping voltammetry (DPASV) (Cd, Pb), hydride atomic absorption spectrometry (AAS) (Se), and cold vapor AAS (Hg) were applied.
