Zhu Y, et al. - Researchers examined the effect of serum ferritin, transferrin, soluble transferrin receptor, and hemoglobin on blood pressure and incident hypertension via conducting a prospective cohort study. The study sample consisted of 8,337 adults from the China Health and Nutrition Survey. The link between markers of iron and blood pressure were evaluated via linear regression model, and the relation of markers of iron and hypertension development were examined using Cox regression model. Overall, the investigators noted a positive association of hemoglobin and transferrin levels with blood pressure and incident hypertension in this study.
