D2d Study

 

Study Type
Diabetes/Prevention
Study Purpose

Are you at risk for type 2 diabetes? Risk factors include: family history of diabetes, overweight, sedentary lifestyle and diabetes during pregnancy.

The U.S. Centers for Disease Control and Prevention estimated in 2012 that 12.3% of adults in Louisiana had been told by their doctor that they have diabetes. This national research study will investigate whether taking vitamin D can prevent diabetes in people who are at high-risk for the disease. As a food ingredient or dietary supplement, vitamin D is generally recognized as safe. However, we do not know if vitamin D is effective in preventing diabetes.

About the Study
The national D2d study is a clinical research trial for people at high risk for developing diabetes. Study participants will be seen at Pennington Biomedical Research Center and followed for four years. During the study, participants will have testing for diabetes at no cost. D2d is sponsored by the National Institutes for Health, National Institute of Diabetes and Digestive and Kidney Diseases, NIH Office of Dietary Supplements, the American Diabetes Association and the National Diabetes Education Program.
