Vitamin D and calcium may lower diabetes risk

NEW YORK (Reuters Health) - Women with high intakes of vitamin D and
calcium appear to have a lower risk of developing type 2 diabetes,
according to Boston-based researchers.

Dr. Anastassios G. Pittas, of Tufts-New England Medical Center and
colleagues looked at data on 83,779 women enrolled in the Nurses'
Health Study. The women had no history of diabetes, cardiovascular
disease or cancer when they enrolled in the study. Vitamin D and
calcium intake from foods and from supplements were evaluated every
2 to 4 years.

A total of 4843 new cases of diabetes were documented over 20 years
of follow-up.

"Based on the latest guidelines set by the Institute of Medicine,
only 3% of women in our cohort had adequate vitamin D intake, and
only 24% had adequate calcium intake," Pittas's group reports in the
medical journal Diabetes Care.

Total vitamin D intake was not significantly associated with type 2
diabetes, but there was a difference when it came to vitamin D
supplements. The team saw a 13 percent lower risk of diabetes among
women in the highest versus the lowest category of vitamin D intake
from supplements.

Women with the highest total calcium intake had a 21 percent lower
risk of diabetes than those with the lowest intake. In this case,
the source of calcium didn't make much difference: the risk was 18
percent lower among women in the highest versus the lowest category
of calcium intake from supplements.

Overall, the lowest risk of diabetes was observed among women with
the highest combined intakes of calcium and vitamin D compared with
those with the lowest.

The researchers say their findings could have "important public
health implications," because interventions to raise both vitamin D
and calcium intake "can be implemented easily and inexpensively to
prevent type 2 diabetes."
