Lower vitamin D status in obese compared with normal-weight women despite higher vitamin D intake in early pregnancy.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc and Copper (Supplement) in this randomized controlled trial publication.

The purpose of this study was to compare vitamin D status and intake between obese and normal-weight women during pregnancy.

Why It Was Studied

Pregnancy may affect vitamin D status, especially in obese subjects.

Who Took Part

PubMed tags the participants as women only.

Twenty-five obese and 80 normal-weight women were recruited in the Western Sweden region (latitude 57°N).

How the Study Was Run

In design terms this was a randomized study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Blood samples and information on diet and sun exposure were collected in each trimester during pregnancy.

What Was Measured

PubMed files the paper under topics including Body Composition, Body Mass Index, Diet, Dietary Supplements, Energy Intake, Maternal Nutritional Physiological Phenomena and Obesity.

Author keywords: 25(OH)D, Pregnancy, Supplement use, Vitamin D intake and Vitamin D status.

What This Means in Plain Language
