Abstract

Background: Iron is one of the micronutrients that necessary for cellular functions to ensure the normal development of the fetus. However, in addition to the positive effects, iron overload in the body causes oxidative stress, which can lead to insulin resistance, as well as reduce function of pancreatic β cells. This becomes a double-edged sword in pregnancy. Objective: The aim of the study was to determine the relationship between serum iron and ferritin levels with GDM. Methods: A case control study (ratio 1:2) was conducted with 192 pregnant women from 24 to 28 weeks of gestation who have antenatal care at SaiGon International OB-GYN Hospital, from December 2020 to April 2021 (64 pregnant women with GDM as cases & 128 pregnant women without GDM as controls according to diagnostic criteria of the American Diabetes Association, 2018). Venous blood samples in 75-g 2-hour oral glucose tolerance test were used for estimation of serum iron and ferritin. Result: Group with serum ferritin levels ≥ 30 ng/mL increased the risk of gestational diabetes to 5,04 (OR*= 2,01; KTC 95%: 1,71 – 14,79), p < 0,05. Conclusion: There was no association found between iron serum levels and GDM, but high ferritin level was associated with an increased risk of GDM.
