Researcher to study role of vitamin D in depressed women with diabetes

A Loyola University Chicago Niehoff School of Nursing researcher has received a 4 year, $1.5 million grant to study vitamin D and mood in depressed women with diabetes.

One in 10 people in the US has diabetes, with the incidence expected to climb to 1 in 4 by 2050. Research has shown that women with type 2 diabetes experience worse outcomes than men with the disease. This difference may be due to depression, which affects over 25% of women with diabetes. Depression may impair a person’s ability to manage the disease.

Lead researcher Sue M Penckofer, PhD, RN and colleagues hypothesize that women supplementing with vitamin D will report fewer depressive symptoms. Due to their improved mood, they may be more able to effectively manage their diabetes by eating well, taking medications, and getting regular exercise.

The study will also observe whether vitamin D reduces blood pressure, overall inflammation, and improve how women manage their disease.

Dr Penckofer and colleagues will enroll 180 women with type 2 diabetes, exhibit symptoms of depression, and have low vitamin D levels. The participants will be randomly assigned to receive either weekly vitamin D supplementation of 50,000 IU or a weekly placebo for 6 months.

The study is titled “Can the Sunshine Vitamin Improve Mood and Self-Management in Women with Diabetes?” We’ll follow the study and report results once the research is published.
