Correlation of serum antioxidant minerals with blood lipid parameters in obese middle school students

초록

The purpose of this study was to investigate the relationships of obesity, serum antioxidant mineral concentrations and blood lipid parameters in middle school students. Subjects were assigned to two groups, obese (BMI> 25, 32 boys, 24 girls) and normal group (18.5<BMI<23, 27 boys, 30 girls). Subjects were evaluated based on anthropometic measurements, 24-hr dietary recalls and blood analysis. The mean age of all subjects was 13.8 years. The mean weight (p<0.001), BMI (p<0.001) and body fat (p<0.05) of obese were higher than those of normal group. There were significant differences in serum HDL-cholesterol, LDL-cholestrol, Mn and Zn concentrations between the obese and normal groups. Anthropometric measurements of the subjects were significantly inversely correlated with serum Mn and Zn, and positively correlated with blood lipids. Serum total and LDL-cholesterol were negatively correlated with serum Mn and Zn, and positively correlated with serum Cu and Cu/Zn ratio.
