Relation between serum lipoperoxide concentrations and iron or copper status over one year in Cuban adult men

The aims of this study were to determine the relations between iron and cop per status and Lipid peroxidation at different periods over one year in Low -income and Low-energy intake healthy subjects. The study was conducted in 199 middle-aged healthy Cuban men from March 1995 to February 1996. Iron st atus was assessed by the determination of serum ferritin, transferrin satur ation, whole blood hemoglobin and iron intakes. Copper status was evaluated by the determination of serum copper and copper intakes. Serum thiobarbitu ric acid substances (TBARS) determination was used as an index of Lipid per oxidation. Rank correlations were observed between serum TBARS concentratio ns and iron or copper status indices at different periods. In period 3 (end of the rainy season), serum TBARS and ferritin concentrations were maximum whereas blood hemoglobin Levels and iron intake were minimum. Serum TBARS concentrations were significantly higher than the reference values of the L aboratory whereas, iron and copper status were within the reference ranges. These results suggested that iron and copper status may be associated with Lipid peroxidation in subjects without metal overloads and that variations over the year needed to be taken in account.
