Introduction: Individuals with diabetes mellitus have been considered as a group at risk
of showing deficiency of micronutrients and some vitamins. Accordingly, women
with gestational diabetes mellitus (GDM) have also been identified as a group
at risk of presenting low levels of vitamin A, however, research in this field
has come to different conclusions. The present study aimed to evaluate the
relationship of gestational diabetes mellitus with serum level of vitamin A. Materials and Methods: This was a case-control study in which 41 pregnant women with GDM and 41
healthy women were recruited. Two groups were matched regarding age,
gestational age and body mass index. A 5 ml venous blood sample were drawn and analyzed with the high performance liquid
chromatography for measuring retinol and. At last data were analyzed through
Chi-square and t test. Results: The mean serum retinol of the GDM group was 0.46 µg/dl and in the control
group it was 0.59 mg/dl (p = 0.01). Conclusion: The level of retinol in the diabetic pregnant women was significantly
lower than that in the control group. This reduction may be due to the reduced
antioxidant vitamins such as vitamin A in women with GDM.
