The relationship between low maternal serum vitamin D levels and glycemic control in gestational diabetes assessed by HbA1c levels: an observational cross-sectional study.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as an observational study.

The aim of this study was to assess the relation between the levels of 25-hydroxy-cholecalciferol (vitamin D), and the glycemic control in pregnant women.

Why It Was Studied

During pregnancy, this deficiency is even more critical.

Who Took Part

According to the abstract, 160 women were involved.

By PubMed's age tags, the people studied were young adults and adults, women only.

An observational cross-section study including 160 pregnant women between 20-40 years in age, in their third trimester, divided into two equal groups.

First group consisted of 80 women with established diagnosis of gestational diabetes and the second group with proved normal blood glucose levels.

How the Study Was Run

The researchers assessed vitamin D in serum, fasting blood glucose, serum insulin and glycosylated hemoglobin (HbA1c) levels and the researchers depicted the insulin sensitivity using the Quantitative insulin sensitivity check index (Quicki).

The results were collected and statistically correlated.

What Was Measured

PubMed files the paper under topics including Blood Glucose, Calcifediol, Cross-Sectional Studies, Diabetes, Gestational, Fasting, Glycated Hemoglobin and Insulin.

What This Means in Plain Language
