Abstract

Zinc is one of the most important micronutrient with essential role in biochemical regulation
of the body functions. The importance of zinc in pregnancy period was widely studied in
various countries. Variation in zinc plasma levels during pregnancy needs more
investigation, because maternal zinc deficiencies may cause some severe abnormalities in the
fetus. In this study the plasma levels of zinc in pregnant women admitted in the hospital
during the third trimester were determined and compared with normal values in nonpregnant
women. Blood samples were collected from pregnant and non-pregnant cases (32
subjects in each group) and zinc levels were measured based on curve plotted by standard
values (100, 200, 300 and 400 mg/l). Values under 75 μg/dl and 75 to 85 μg/dl were
defined as severe and moderate. The results showed that mean plasma concentration of zinc
among pregnants was 65.49±15.34 compare with that in non-pregnant women, which was
significantly lower (P<0.05). Zinc deficiency in third trimester of gestation could be due to
malnourishment or other conditions such as plasma expansion during pregnancy. Enhancing
the daily uptake of zinc at the third trimester could be supportive.
