Low vitamin D levels are not linked to an increased risk of type 2 diabetes, according to a study published in Diabetes Care.  In the study Dr. Jennifer G. Robinson, a professor of epidemiology and medicine at the University of Iowa, and researchers followed women participating in the Women’s Health Initiative Clinical Trials and Observational Study (a racially and ethnically diverse population of postmenopausal women) who were free of diabetes. Diabetes was defined as self-report of physician diagnosis and receiving insulin or oral hypoglycemic medication.

Of 5,140 women who were free of type 2 diabetes at the start of the trial, 6 percent developed the disease over an average of 7 years.

The researchers found no clear link between the women’s blood levels of vitamin D at the outset and their risk of developing type 2 diabetes later on.
