SERUM CALCIUM WAS NEGATIVELY ASSOCIATED WITH SERUM IRON AMONG GENERAL POPULATION: FINDINGS FROM A CROSS-SECTION STUDY.

Introduction: The progression of ferroptosis has been found to be associated with the onset and progression of many diseases. Disruption of iron homeostasis can lead to ferroptosis. We had previously hypothesized that vitamin D may affect serum calcium levels, which in turn regulates ferroptosis by regulating serum iron levels. However, the relationship between serum calcium level and serum iron level is unclear. The purpose of our study was to explore the relationship between serum calcium level and serum iron level among general population in Taizhou, China.

Methods: In this study, a cross-sectional study was conducted. Serum calcium levels and serum iron levels were determined in our work. Pearson's correlation analysis was used to determine the association between serum calcium level and serum iron level.

Results: The results showed that serum iron level was negatively correlated with serum calcium level and age. After controlling for age, sex and marital status, serum iron level was still negatively correlated with serum calcium level.

Conclusions: The results suggest that improving serum calcium levels may be a potential strategy for regulating iron metabolism homeostasis. Whether calcium supplementation can reduce serum iron levels in people with low serum calcium levels needs further investigation.
