Vitamin D Deficiency Linked To T2 Diabetes
By Mike Boyle

According to the results of a new study, presented at the recent Endocrine Society`s 92 Annual Meeting in San Diego, vitamin D deficiency is highly prevalent in patients with type 2 diabetes and may be associated with poor blood sugar control.

Vitamin D is found in many dietary sources such as fish, eggs, fortified milk, and cod liver oil. The sun also contributes significantly to the daily production of vitamin D, says the Mayo Clinic.

"This finding supports an active role of vitamin D in the development of type 2 diabetes," said study co-author Esther Krug, MD, an assistant professor of medicine at The Johns Hopkins University School of Medicine and an endocrinologist at Sinai Hospital, Baltimore.

The researchers reviewed the medical charts of 124 patients with type 2 diabetes who came to an endocrine outpatient clinic for specialty care from 2003 to 2008. Patients` age ranged from 36 to 89 years. More than 90 percent of the patients had either vitamin D deficiency or insufficiency, Krug`s team found, despite the fact that they all had had routine primary care visits before their specialty visit.
Only about 6 percent of the patients were taking a vitamin D supplement at the time of their visit, the researchers noted, and those who had lower vitamin D levels were also more likely to have higher average blood sugar levels, reports BusinessWeek.com.

"Since primary care providers diagnose and treat most patients with type 2 diabetes," Krug added, "screening and vitamin D supplementation as part of routine primary care may improve health outcomes of this highly prevalent condition."
