Researchers at the University of California San Diego and Seoul National University report that person with 25-hydroxyvitamin D levels below 30 ng/ml have a 5 times greater risk for developing type 2 diabetes than people with levels above 50 ng/ml.
The prospective cohort study enrolled 904 healthy adults with a mean age of 74 years and followed them for 10 to 12 years. During that time 337 patients developed pre-diabetes and 47 patients developed diabetes. Persons with 25-hydroxyvitamin D levels > 50 ng/ml had an HR = 0.19, CI = 0.06–0.56 when compared to individuals with 25 hydroxyvitamin D levels < 30 ng/ml. This means that individuals with higher 25-hydroxyvitamin D levels had an 81% decreased probability of developing prediabetes or diabetes. Multiple recent research studies have found strong correlations between low levels of vitamin D and depression , dementia, schizophrenia, type 2 diabetes, and hypertension yet supplementation with pharmacologic vitamin D has not been proven to be as beneficial as outdoor activities to raise vitamin D levels. There is a real possibility that sedentary behavior and lack of exercise is the confounding factor in this correlation between vitamin D and diabetes. After all lack of exercise leads to increased glucose, increased adiposity, hypertension, hyperglycemia and for many people decreased exposure to the sunshine which is necessary for vitamin D formation.
