| Introduction: Iron deficiency anemia is recognized as the most prevalent nutrient deficiency in pregnancy and iron supplements, which are prescribed daily in pregnant women for prevention of this anemia, may lead to unfavorable effects in zinc absorption. The aim of this study was to assess the effects of ferrus sulfate tablets on serum zinc in pregnant women. Material and Methods: In a historical cohort study, among all pregnant women at third trimester who visited health centers, 20 pregnant women who had not taken iron tablets (Tl) and 21 pregnant women who took iron tablet (DTI) were randomly selected. Serum zinc levels were measured by atomic absorption spectrophotometry and serum iron, TIBC, and ferritin levels were measured by spectrophotometer. The mean daily intakes of nutrients were estimated by using 24-hour dietary recall questionnaire and FP2 software. The data were analyzed statistically using student’s t-test, χ2 and Pearson’s correlation coefficient. Results: In case group, the mean intake of zinc increased signifcantly after iron intake compared with control group (P<0.05). There was a significant negative correlation between serum zinc concentration and TIBC of cases (P<0.05). There was a significant difference between mean serum iron and TIBC in two groups, but no significant difference between the mean serum zinc levels of cases compared with the controls. Conclusion: Iron supplementation does not affect serum zinc status of pregnant women. Serum zinc levels of 17.2 percent of pregnant women were lower than normal range. |
