Abstract

The purpose of this study was to investigate the status of magnesium, iron, copper and zinc nutrition in 28 normal and 28 obese male elementary school students who have over 30% obesity index. The anthropometric measurements, dietary intakes and serum levels of magnesium, iron, copper and zinc were determined by 24-hr recall method and blood analysis, respectively. The mean age, height, weight, and obesity index were 10.9years, 147.4cm, 61.1kg, and 50.5% in obese group and 10.8years, 145.4cm, 40.2kg, and 3.3% in normal group. There was no significant difference in average daily food intake between obese and normal group, but meats(p＜0.05) intake of obese group was significantly lower than that of normal group. The intakes of energy, magnesium, iron, copper were not significantly difference between obese and normal group, but heme iron(p＜0.05) intake of obese group was significantly lower than that of normal group. Zinc(p＜0.05) intake of obese group was significantly higher than that of normal group. Serum magnesium(p＜0.001) level of obese group was significantly higher than that of normal group, but there were no significant differences in serum iron, copper, zinc levels between obese and normal group. There was a significantly positive correlation between serum magnesium and weight(p＜0.05), and obesity index(p＜0.05). There was a significantly positive correlation between serum magnesium and energy intake(p＜0.05), protein intake(p＜0.05), animal protein intake(p＜0.05), phosphorus intake(p＜0.05) and animal iron intake(p＜0.05). There was a significantly positive correlation between serum magnesium and seaweeds intake(p＜0.05), milks intake(p＜0.001). Also, there was significantly positive correlation between serum copper and oils and fat intake(p＜0.05). These results suggest that there should be careful considerations for micronutrients nutrition status among male obese elementary school students.
