A study has found that storing abnormal amounts of iron in the body can lead to adult onset diabetes in women, raising the possibility that a blood test earlier in life could help identify those at risk from the disease, researchers said on Tuesday. The finding came from a look at 698 women among thousands of nurses who gave blood samples between 1989 and 1990 as part of a multiyear study. The 698 women developed diabetes over the course of the study even though they were free of it and free of heart disease as well at the start.
