Low serum levels of trace elements (iron, zinc and copper) is associated with increasing number of pregnancies among Omani women: a case‐control study (1042.10)

Background: A repeated pregnancy along with inadequate dietary intake might contribute to different nutrients depletion, including trace elements (iron, zinc and copper). These trace elements have a vital role in fetal growth and are cofactors in numerous enzymatic reactions. Objective: This case‐control study was planned to evaluate dietary intake and serum levels of iron, zinc and copper of postpartum Omani women as compared to age and weight matched non‐pregnant control subjects. Methods: This study involved 100 Omani women [(post partum group, (n=70) and control group, females with no history of pregnancy, (n=30)]. Dietary intake was evaluated using a semi‐quantitative food frequency questionnaire, mean while iron, zinc and copper were measured in the sera of the study subjects by Atomic Absorption Spectrophotometer. Results: There was no statistical significant difference between postpartum women and control group with regard consumption of foods containing iron, zinc and copper. The mean serum levels of iron, zinc and copper in the control subjects were the highest as compared to postpartum women group who had 4‐8 pregnancies, and postpartum women group who had 1‐3 pregnancies. Conclusion: Among the studied Omani women; low serum levels of trace elements were prevalent. This sheds light on the importance of increasing the intake of trace elements supplements among Omani women during reproductive age.
