Aims: Iron overload identified by elevated ferritin concentrations has been implicated in risks of altered glucose metabolism and diabetic complications. The relationship between ferritin and insulin resistance in different gender and ethnicities remains uncertain; this study aimed to investigate it using homeostasis model assessment (HOMA-IR), and to explore whether it is gender-specific.
Methods: A total of 524 type 2 diabetic patients were selected cross-sectionally from a cohort participating in a diabetic control study in Taiwan.
