Abstract
Purpose
The deficiency or excess of serum zinc in pregnancy may threaten the health of the mother and the fetus. The purpose of this study is to determine the pattern of serum zinc in pregnant women covered by Urmia urban health centers and its association with some nutritional and clinical determinants in the third trimester, from July to December 2018.
Design/methodology/approach
In this analytic cross-sectional study, of six selected health centers in Urmia, 400 pregnant women subjects who were in their third trimester were recruited in a simple random manner. The nutritional, demographic, clinical data as well as fasting blood samples were taken from each of the subjects. The data were analyzed using chi-square, independent t-test and logistic regression tests.
Findings
The study revealed that about 3 per cent of pregnant women had zinc deficiency, 70.2 per cent were normal and 26.8 per cent had high serum zinc levels. In 388 pregnant women (72.4 per cent with normal serum zinc and 27.6 per cent with high serum zinc), binary logistic regression model showed that high concentration of serum zinc was directly associated with dietary intake zinc (OR: 2.252; 95 per cent CI: 1.85-2.74), supplement zinc (OR: 7.823; 95 per cent CI: 3.676-16.649) and total intake magnesium (OR: 1.005; 95 per cent CI: 1.000-1.01) and inversely associated with frequent reproductive cycling (OR: 0.739; 95 per cent CI: 0.569-0.959).
Originality/value
Pregnant women in Urmia probably have high concentrations of serum zinc, and it is likely related to consumption of the zinc supplementation. Supplementation programs need to be scaled up for pregnant women that take inadequate dietary zinc.
