Researchers at Tufts Medical Center (Boston, MA) and Cincinnati VA Medical Center (Cincinnati, OH) are conducting a research study in adults with type 2 diabetes to see whether daily vitamin D supplementation affects how the body processes glucose (sugar). A better understanding of vitamin D on glucose metabolism may lead to new treatments for type 2 diabetes.
According to the Centers for Disease Control and Prevention, about 26 million Americans have diabetes and about 80 million more are at risk for developing diabetes. Persons who are older than 45 years of age, are overweight, have a family member with type 2 diabetes, have high blood pressure, or do not get enough exercise are at risk for type 2 diabetes. Women who had diabetes during pregnancy and people of certain races and ethnicities are also at risk.
Participants will be enrolled in the DDM2 study at two locations:
Tufts Medical Center, Boston, MA
Principal Investigator: Anastassios G. Pittas, MD MS
Cincinnati VA Medical Center,Cincinnati, OH
Principal Investigator: David D’Alessio, MD
If you take supplements containing vitamin D or calcium, you must agree not to take any multivitamin or other preparations containing vitamin D or calcium during the trial, in excess of what what is recommended by the Institute of Medicine recommendations.
Ineligibility will be determined based on:
Diabetes medications,other than metformin
History of kidney stones or kidney disease
Pregnancy or the intent to become pregnant within the next year, or currently breastfeeding
Any other medical condition that in the opinion of the site investigators may put the participant at increased risk of harm
If you are interested in participating, please contact us for a brief interview over the telephone and, if eligible, a screening visit at Tufts Medical Center in Boston MA or Cincinnati VA Medical Center in Cincinnati OH.
