The Loyola University Chicago Marcella Niehoff School of Nursing (MNSON) plans to test the effect of vitamin D supplementation on insulin resistance and depression in diabetic women.
“Vitamin D deficiency continues to be a problem despite the nutrient’s widely reported health benefits,” noted Sue Penckofer, PhD, RN, a professor at the MNSON. “Chicago winters compound this issue when more people spend time away from sunlight, which is a natural source of vitamin D.”
Diabetic women with insulin resistance have a tendency to be depressed along with impaired blood sugar control. This problem is more common in women than men. Higher vitamin D levels have been shown to be associated with a reduced risk of depression, diabetes and other ailments.
The University will administer about 7,000 international units of vitamin D per day to 80 type 2 diabetic women with signs of depression and between 18 to 70 years of age. Participants will be evaluated at three time points over a six-month period for serum vitamin D levels and other factors. “There is evidence to suggest that vitamin D supplementation may decrease insulin resistance,” Dr Penckofer commented. “If we can stabilize insulin levels, we may be able to simply and cost effectively improve blood sugar control and reduce symptoms of depression for these women.”
"Vitamin D has widespread benefits for our health and certain chronic diseases in particular," she added. "Our research may shed greater light on the role this nutrient plays in managing two conditions that impact millions of Americans. If proven to be successful, vitamin D may an important addition to care for diabetes and depression."
