Associations between Vitamin D Status and Type 2 Diabetes Measures among Inuit in Greenland May Be Affected by Other Factors.

What Was Tested

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

Epidemiological studies have provided evidence of an association between vitamin D insufficiency and type 2 diabetes.

Who Took Part

The study group was 330 individuals.

By PubMed's age tags, the people studied were teenagers, young adults, adults and middle-aged adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized study.

The individuals were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

2877 Inuit (≥18 years) randomly selected for participation in the Inuit Health in Transition study were included.

Fasting- and 2hour plasma glucose and insulin, C-peptide and HbA1c were measured, and associations with serum 25(OH)D3 were analysed using linear and logistic regression.

A subsample of 330 individuals who also donated a blood sample in 1987, were furthermore included.

What Was Measured

Topics PubMed links to this paper include Blood Glucose, Diabetes Mellitus, Type 2, Glucose Intolerance, Glucose Tolerance Test, Greenland, Inuit and Prediabetic State.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc in 330 individuals.

With several hundred people or more, it is a fairly large study for this kind of research.

Its findings take up roughly 4 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2016 (PloS one), a journal based in United States.
