The iron nutritional status of 328(20-70 years old) women in Seoul and Puyo areas was evaluated using a dietary information and a measurement of hematological indices. The serum iron was measured by Red Blood Cell(RBC), Hemoglobin(Hb), Hematocrit(Hct), Serum Iron(S-Fe), Total Iron Binding Capacity (TIBC), Transferrin Saturation(TS) and Serum Ferritin(SF) and was analyzed with the information obtained by interviews which included socio-demographic variables and the dietary pattern of the subjects. The mean Hb was 12.6 $pm$ 1.21g/dl(Seoul : 12.4 $pm$ 1.14g/dl, Puyo : 13.2 $pm$ 1.28g/dl), Hct was 38.7 $pm$ 3.84%(Seoul: 37.5 $pm$ 3.28%, Puyo: 4.19 $pm$ 3.48%), S-Fe was 76.8 $pm$ 31.49ug/dl(Seoul: 68.8 $pm$ 27.3ug/dl, Puyo: 78.8 $pm$ 32.3ug/dl) and TIBC was 277.7 $pm$ 86.15ug/dl(Seoul: 354.1 $pm$ 129.8ug/dl, Puyo: 259.0 $pm$ 59.55ug/dl). The mean Ts(%) was 30.9 $pm$ 17.9% (Seoul: 21.7 $pm$ 10.52%, Puyo: 33.2 $pm$ 18.68%) and the level was significantly higher in Puyo women(p<0.05). The mean SF was 45.4 $pm$ 46.21ng/ml(Seoul: 53.6 $pm$ 50.21ng/ml, Puyo: 36.1 $pm$ 39.83ng/ml). The Red Blood Cell(RBC) showed a negative correlation with age and Hb, Hct showed a negative correlation with education and income level. However TIBC showed a and total energy expenditure per day. Energy, protein, carbohydrate, iron and vit.C intake showed a positive correlation with Hb and Hct. In particular, heme iron showed a positive correlation with RBC and nonheme iron of Hb, income level and iron intake affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of Hct. In Seoul women, the age of menarche affected on the level of TIBC, total energy expenditure affected on the level of S-Fe.
