| Outline of Final Research Achievements |
We investigated the relation of serum ferritin with subsequent changes in biomarkers associated with glucose metabolism among 575 normoglycemic men without iron overload disorders. The subsequent changes in fasting blood glucose, insulin and HOMA-IR after 3 years were grater in subjects having lower levels of serum ferritin after adjustment for body mass index and other potential confounding factors. However, HOMA-β was similar across serum ferritin levels. Elevated serum ferritin levels may worsen glucose metabolism through insulin resistance among normoglycemic Japanese men without iron overload disorders.
