The Vitamin D and Type 2 Diabetes (D2d) Study

 The Vitamin D and Type 2 Diabetes Study, also known as D2d, is a research study funded by the National Institutes of Health (NIH) and is currently being conducted at KUMC and at 19 other sites nationwide. Diabetes is a serious condition affecting about 1 in 10 people in the United States.  We are investigating the effects vitamin D has on the progression from pre-diabetes to diabetes.  The goal of the study is to see whether taking vitamin D can lower the risk of getting diabetes in people who are pre-diabetic. 

We are looking for men and women 30 years of age and older who have been told they are at risk for diabetes or think they might be.  We will do blood testing to confirm that you are pre-diabetic before you are enrolled in the study.  Some of the risk factors for being pre-diabetic include:

  • Being aged 45 or older
  • Being overweight or obese
  • Having a family member with diabetes
  • Having high blood pressure
  • Being a woman who had diabetes during pregnancy

If you decide to participate in the study, you will receive either a vitamin D or a placebo (sugar) pill for the duration of the study, approximately 3 to 4 years.  In-person visits will take place every 3 months for the first 6 months of the study and then every 6 months for the remainder of the study period.  You will receive lifestyle counseling (diet and exercise) and will be invited to take part in diabetes education sessions and support groups. In addition to free counseling and medical monitoring, you will receive $50 to $75 for completing most in-person visits and $10 for completing brief scheduled telephone updates between in-person visits.  In-person visits will take place at the KU Clinical Research Center in Fairway, Kansas. Free parking is available at the Research Center.

More information about the D2d study and about other sites participating in the research can be found on the D2d website.
