Maternal Serum Zinc Concentration and Pregnancy Outcomes

A study was conducted on a group of 107 women, attending the three peripheral community clinics in Seoul and Kyunggi area for their prenatal care, to ascertain the relationship between maternal serum zinc concentration measured in pregnancy and several pregnancy outcomes. The serum zinc concentration was adjusted for estimated gestational age at the time of drawing blood. Mean daily zinc intake of the pregnant women estimated by a 24-hour recall method was 7.68$\pm$3.70$\mu\textrm{g}$/dl, 51% of RDA. and mean serum zinc concentration of the women was 94.03$\pm$36.99ug/dl. Adjusted maternal serum zinc level was significantly related to gestational maternal weight gain(p<0.05) and infant birth weight(p<0.05). Pregnant women with tgreater than 9kg weight gain during the gestation period had higher adjusted serum zinc levels than the subjects with less than 8kg weight gain. Adjusted serum zinc levels of mothers who delivered 3.0-3.5kg and greater than 4.0kg birth-weight infants were higher than those of mothers of low-birth-weight infants. Any association between maternal serum zinc level and gestational length, complications and morning sickness was not observed. There results suggest that the maternal serum zinc level may predict perhaps the author could be none specific.
