Insufficient levels of vitamin D may increase the risk of metabolic syndrome by about 40% in seniors, suggests a new Dutch study.
In the study, blood samples of 1,289 white Dutch men and women aged 65 and older where analyzed to assess vitamin D levels (1). The results showed that almost 50% of participants were vitamin D deficient and about 37% of the total sample had metabolic syndrome. People with blood levels of vitamin D (serum 25-hydroxyvitamin D) lower than 50 nanomoles per liter were likelier to have metabolic syndrome than those whose vitamin D levels exceeded 50 nmol/L. No differences in risk were observed between men and women.
The researchers commented that because metabolic syndrome increases the risk of diabetes and cardiovascular disease, an adequate vitamin D level in the body might be important in the prevention of these diseases. Vitamin D deficiency has previously been linked to impaired insulin secretion in humans, and has also been linked to insulin resistance in healthy subjects.
Metabolic syndrome is a condition characterized by obesity, hypertension, and disturbed glucose and insulin metabolism. The syndrome has been linked to increased risks of both type-2 diabetes and cardiovascular disease.
