Low Levels Of Serum 25-Hydroxyvitamin D And Risk Of Metabolic Syndrome In China

Recent evidence indicates the potential role of vitamin D in the prevention of Metabolic syndrome (MetSyn). This is an analytical cross sectional study. A total of 3275 subjects were investigated. 25-hydroxyvitamin D(25[OH]D) was detected by electrochemiluminescence immunoassay (ECLIA) technology. Metabolic syndrome was defined according to the definition of International Diabetes Federation (IDF). Among the participants, the prevalence of the MetSyn was 6.0%. The prevalence of vitamin D deficiency and insufficiency was 50.1% and 25.0% respectively. Subjects with MetSyn presented with significantly lower 25(OH)Vit D serum levels compared with non-MetSyn group. The results shows that vitamin D deficiency is common in Chinese adults, and subjects with lower serum 25(OH)D have a higher risk of the MetSyn. The cut-off value of serum 25(OH)D that reflected MetSyn in Chinese adluts was 15.655 ng/mL.
