Nutrition intakes and its relations to the obesity rate and the prevalence of anemia in preschool children from metropolitan area of Korea

초록

This study was designed to investigate nutrition intakes and its relation to the obesity rate and the prevalence of anemia in 252 children(136 boys, 116 girls) aged 2∼6 years. The height, weights and the hematological parameters of the children were measured. Calorie intakes of 2 and 3 years old children were over their RDA while those of 4-6 years were below the RDA. Intakes of protein, P, and vit B complex were far over the RDA in all ages of children. Fe and vit A intakes were insufficient in all ages except 3 years while Ca intakes were insufficient in all ages except 2 and 3 years. Very few children were evaluated as anemic by the hematologic parameters. The mean HB concentration was 12.2㎎/㎗ in boys and also in girls. The mean Hct was 36.2% for boys, 35.8% for girls. Serum Fe concentration was 100.1㎍/㎗ in boys, 101.1㎍/㎗ in girls. RBC count was significantly higher in boys while MCH was significantly higher in girls(28.6 vs 24.2pg). Intakes of protein, P, Fe, vit B1, niacin, vit C were significantly higher in obese group compared to underweight group. There was significant positive correlations between protein intake and Hb, Hct, MCH, and MCHC. The correlation between Fe intake and Hb or Hct was not significant. In conclusion, it seems that the nutritional status of the most children was in very good condition. However, they needed to take more foods supplying Fe, Ca, and vit A.
