Association of body fat and vitamin D status and the effect of body fat on the response to vitamin D supplementation in Pakistani immigrants in Denmark.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

The aims were to assess the possible relationship between body fat and vitamin D status, and to investigate the effect of body fat on the response to oral vitamin D supplementation in Pakistani immigrants in Denmark.

Why It Was Studied

Vitamin D deficiency and obesity are both prevalent conditions in the northern countries, especially among immigrants.

Data were obtained from a 1-year double-blind randomised controlled trial with oral vitamin D supplementation.

Who Took Part

According to the abstract, 122 women were involved.

The age groups tagged for this paper are adults and middle-aged adults, women only.

How the Study Was Run

The researchers set it up as a randomized, double-blind and placebo-controlled 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.

Blinding on both sides kept the women and researchers unaware of who received Vitamin D, K2, Magnesium and Zinc.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

PubMed files the paper under topics including Adipose Tissue, Body Composition, Cholecalciferol, Denmark, Dietary Supplements, Emigrants and Immigrants and Linear Models.
