A few studies found that 25- OH-D plasma levels was associated with gestational diabetes mellitus (GDM). Considering the uncertainty of opinion in this field, we decided to study the serum level of 25-hydroxy vitamin D in the GDM and non GDM pregnant women referred to Azad University Hospitals in Tehran between 2016 and 2017. Materials and methods: In this case-control study, 96 pregnant women, including 48 with GDM and 48 normoglycemic subjects, referred to Azad University Hospitals in Tehran between 2016 and 2017 were studied. 25-OH-D levels in patients and control groups were evaluated. Data were analyzed by SPSS (ver.22) using independent t- test, Chi- square test and Pearson correlation test. Results: 96 pregnant women with mean age of 30.07± 5.67 years were studied. There was no significant difference in the number of gravida, para, BMI and mean age between two groups. Mean FBS, and results of 1- hour, 2-hour and 3-hour GT were significantly different between two groups. Mean serum levels of vitamin D was not significantly different between GDM (21.41 nmol/l) and non- GDN (18.21 nmol/l) groups. Conclusion: Among with GDM and non GDM pregnant women in second-trimester, there was no significant difference in serum vitamin D levels.
