Serum ferritin concentration in early pregnancy and risk of subsequent development of gestational diabetes: A prospective study.

Background: Elevated serum ferritin concentration is associated with insulin resistance and diabetes. Recently it has also been described in gestational diabetes mellitus (GDM).

Objective: A prospective study was done to determine whether there was a relationship between serum ferritin concentration in early pregnancy and the risk of GDM.

The effects of vitamin D supplementation on maternal and neonatal outcome: A randomized clinical trial.

Background: Vitamin D supplementation during pregnancy has been supposed to defend against adverse gestational outcomes.

Objective: This randomized clinical trial study was conducted to assess the effects of 50,000 IU of vitamin D every two weeks supplementation on the incidence of gestational diabetes (GDM), gestational hypertension, preeclampsia and preterm labor, vitamin D status at term and neonatal outcomes contrasted with pregnant women that received 400 IU vitamin D daily.

Materials And Methods: 500 women with gestational age 12-16 weeks and serum 25 hydroxy vitamin D (25 (OH) D ) less than 30 ng/ml randomly categorized in two groups.

The effect of different doses of vitamin D supplementation on insulin resistance during pregnancy.

Low serum vitamin D levels are correlated with insulin resistance during pregnancy. We have assessed the effects of different doses of vitamin D on insulin resistance during pregnancy. A randomized clinical trial was done on 120 women with a gestational age of less than 12 weeks.
