Officials at the University of Kansas Medical Center seek volunteers for a large-scale clinical trial to see if vitamin D helps prevent or delay type 2 diabetes.
The study, funded by the National Institutes of Health, will take place at 20 sites across the U.S. and involve about 2,500 people.
Officials said the goal of the multiyear study would be to see if people. Its goal is to learn if vitamin D will prevent or slow diabetes in adults age 30 or older who have been diagnosed as prediabetic. People with prediabetes have blood glucose levels that are higher than normal but not high enough to be called diabetes.
“People in the Kansas City region have an important opportunity to be part of a national effort to determine whether simple vitamin D might help address the public health crisis of diabetes,” said Dr. David C. Robbins, director of the KU Diabetes Institute.
KU Medical Center is one of 20 academic medical centers conducting the study. Other sites include Baylor College of Medicine, Duke University Medical Center, Northwestern University and Stanford University Medical Center.
Officials said it would be the first study to directly examine if a daily dose of 4,000 International Units of vitamin D would be beneficial to those with prediabetes. The typical adult intake of vitamin D is between 600 and 800 IUs a day.
Earlier studies suggest that vitamin D could reduce diabetes risk by 25 percent.
“An estimated 79 million Americans have prediabetes, and nearly 26 million more have diabetes,” said Dr, Griffin P. Rodgers, director of the National Institute of Diabetes and Digestive and Kidney Diseases, which is part of the NIH. “We seek evidence for an affordable and accessible way to help prevent or delay type 2 diabetes.”
Half the study participants will receive vitamin D. The other half will receive a placebo – a pill that has no drug effect. Participants will have check-ups twice a year and will receive regular health care through their own providers.
