The purpose of this study was to compare the food behavior and nutrient intakes, and the analysis of constituent parts of blood related to iron nutrition conditions and to investigate the correlation between iron nutrition conditions and obesity. Each subject was assigned to one of such as normal(n=55) and obese groups(n=60) according to their obesity index. Their nutritional status, serum iron status were evaluated based in 24-hr dietary recalls, questionnaire and blood analysis. The mean age of the normal group(10.76 years) and that of the obese group(10.95 years) made little difference. The height(p<0.05), weight(p<0.001), and obesity index(p<0.001) in the obese group were higher than those of the normal group in every respect. The 63.55% of the subject of this study gave an answer ’They eat breakfast daily’, and the frequency of eating breakfast made little difference. The average intakes of energy were 1669.44 kcal(84.19% of EER) in the obese group and 1673.59 kcal(86.72% of EER) in the normal group respectively, which made little difference between two groups. The intake of nutrients such as calcium and folate was as insufficient as below 75% of RI. The heme iron intake of the obese group was low that of the normal group(p<0.05). Among the major 20 iron resources the iron intake through animal food intake were 1.43 mg(12.00%) in the obese group and 1.93 mg(17.72%) in the normal group respectively. The rating of iron condition in the blood showed that the number of red blood cell(p<0.01), the hemoglobin(p<0.001), and hematocrit(p<0.01) of the obese group were lower than those of the normal group. These results suggest that there should be the right choice of food according to its bioavailability and nutritive guidance to appropriate food behavior, in addition to increasing iron intake to improve iron nutrition conditions of obese male elementary school students.
