Liu JR, et al. - In this cross-sectional study, researchers determined if serum ferritin (SF) has any impact on cardiovascular risk factors in first-degree relatives with family history of type 2 diabetes (FHD). Overall, 232 men were included, and an analysis of anthropometric measurements and blood samples was carried out. Four groups were defined based on median SF (102.8 ng/ml) and presence or absence of FHD: Group A (FHD- and low SF), group B (FHD- and high SF), group C (FHD+ and low SF), and group D (FHD+ and high SF). The risk of cardiovascular risk factors and the occurrence of insulin resistance in first-degree relatives with family history of diabetes was increased due to elevated SF level.
