The effect of pregnancy vitamin D supplementation on maternal blood pressure: real-world data analysis within the MAVIDOS randomised placebo-controlled trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc in the context of low blood pressure and orthostatic hypotension, published as a randomized controlled trial.

Data from intervention studies are limited.

Who Took Part

PubMed indexes the participants as adults, women only.

BP recordings documented during routine clinical pregnancy care were obtained from clinical records and grouped into gestational windows based on the schedule for routine antenatal care in the United Kingdom (23+0-24+6, 27+0-28+6, 33+0-35+6, 37+0-38+6, 39+0-40+6 and ≥ 41+0 weeks+days).

Systolic and diastolic BP measurements in these gestational windows were compared between randomisation groups.

How the Study Was Run

The design is described as randomized and placebo-controlled.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

The Maternal Vitamin D Osteoporosis Study (MAVIDOS) was a randomised placebo-controlled trial.

Diagnoses of PIH or PET (in accordance with national guidelines) and the use of antihypertensive agents were also noted and compared between groups.

What Was Measured

Topics PubMed links to this paper include Vitamin D, Blood Pressure, Dietary Supplements, Hypertension, Pregnancy-Induced, Pre-Eclampsia, Cholecalciferol and Vitamins.
