The Effect of Multi mineral-Vitamin D Supplementation on Pregnancy Outcomes in Pregnant Women at Risk for Pre-eclampsia.

Abstract

BACKGROUND:

The objective of this study was to determine the favorable effects of multi mineral-Vitamin D supplementation on pregnancy outcomes among women at risk for pre-eclampsia.

METHODS:

This randomized double-blind controlled clinical trial was conducted among 46 women at risk for pre-eclampsia at 27 weeks' gestation with positive roll-over test. Pregnant women were randomly assigned to receive either the multi mineral-Vitamin D supplements (n = 23) or the placebo (n = 23) for 9-week. Multi mineral-Vitamin D supplements were containing 800 mg calcium, 200 mg magnesium, 8 mg zinc, and 400 IU Vitamin D3. Fasting blood samples were taken at baseline and after 9-week intervention to measure related factors. Newborn's outcomes were determined.

RESULTS:

Although no significant difference was seen in newborn's weight and head circumference between the two groups, mean newborns' length (51.3 ± 1.7 vs. 50.3 ± 1.2 cm, P = 0.03) was significantly higher in multi mineral-Vitamin D group than that in the placebo group. Compared to the placebo, consumption of multi mineral-Vitamin D supplements resulted in increased levels of serum calcium (+0.19 vs. -0.08 mg/dL, P = 0.03), magnesium (+0.15 vs. -0.08 mg/dL, P = 0.03), zinc (+8.25 vs. -21.38 mg/dL, P = 0.001) and Vitamin D (+3.79 vs. -1.37 ng/ml, P = 0.01). In addition, taking multi mineral-Vitamin D supplements favorably influenced systolic blood pressure (SBP) (-1.08 vs. 6.08 mmHg, P = 0.001) and diastolic blood pressure (DBP) (-0.44 vs. 3.05 mmHg, P = 0.02).

CONCLUSIONS:

Multi mineral-Vitamin D supplementation for 9-week in pregnant women at risk for pre-eclampsia resulted in increased newborn's length, increased circulating levels of maternal serum calcium, magnesium, zinc and Vitamin D, and led to decreased maternal SBP and DBP.
