The following is a summary from LEF of a recent research article appearing in the Ocotober 2008 issue of the jounal Diabetes:
Lower vitamin D levels predict increased blood sugar and insulin resistance |
The October, 2008 issue of the journal Diabetes published the outcome of a study of middle-aged men and women which found that lower serum vitamin D levels were associated with an increase in the risk of developing insulin resistance and elevated blood sugar over a ten year follow up period. Researchers at the Institute of Metabolic Science in Cambridge, England followed 524 nondiabetic participants in the Ely Study, a prospective study established in 1990. Upon enrollment, the vitamin D marker serum 25-hydroxyvitamin D, serum parathyroid hormone, insulin-like growth factor-1 (IGF-1) and other factors were measured, and personal health habits such as smoking status and physical activity levels were ascertained. Weight, height, waist circumference, blood pressure, plasma glucose, lipids, and fasting insulin were measured during the initial and ten year follow-up visits. At the end of the follow-up period, having a higher serum vitamin D level was associated with a lower adjusted ten-year risk of elevated blood sugar, insulin resistance, and high metabolic syndrome score. An association between increased IGF-1 levels and metabolic syndrome risk observed in an earlier study was not noted in the current research. |
