Vitamin D status in the Chinese population in the Netherlands: The DRAGON study.

What Was Tested

This observational study looks at Vitamin D, K2, Magnesium and Zinc.

Therefore, an observational study was performed to determine 25-hydroxyvitamin D (25(OH)D) concentrations and to assess potential determinants of low vitamin D status.

A questionnaire was used to assess general characteristics and lifestyle habits.

Why It Was Studied

Vitamin D is essential for bone health since it stimulates the intestinal absorption of calcium and phosphorus from the gut, both necessary for bone mineralization.

However, vitamin D deficiency is highly prevalent among several non-Western immigrant populations in the Netherlands.

Who Took Part

PubMed indexes the participants as adults, middle-aged adults and older adults, both men and women.

Subjects, aged 18 years and older, with a Chinese background and residing in the Netherlands were invited to participate in the study.

How the Study Was Run

Fasting blood samples were obtained in March 2014 to measure serum 25(OH)D concentration, and analysed by liquid chromatography tandem mass spectrometry.

What Was Measured

Vitamin D is essential for bone health since it stimulates the intestinal absorption of calcium and phosphorus from the gut, both necessary for bone mineralization.

Topics PubMed links to this paper include Asian People, Dietary Supplements, Netherlands, Vitamin D, Vitamin D Deficiency and Vitamins.

The authors tagged it with the keywords 25(OH)D, Chinese, Non-Western immigrant and Vitamin D status.
