  • The influence of nutrition during early life on physical growth as well as mental development has been thoroughly discussed in the literature. The physical dimensions of the body are greatly influenced by nutrition, particularly during the period of rapid growth in early childhood. Nutritional status affects every pediatric patient's response toillness. Good nutrition is important for achieving normal growth and development. It is indicated that permanent impairment of the central nervous system may result from dietary restriction of imbalance during certain periods of life. If children under 3 years of age show a good nutritional status, it may be assumed that they are well nourished. Several common diseases of children such as iron deficiency, chronic constipation and atopic dermatitis are known food related diseases. Patients with chronic illness and those at risk of malnutrition should have detailed nutritional assessments done. Components of a complete nutritional assessment include a medical history, nutritional history including dietary intake, physical examination, anthropometrics (weight, length or stature, head circumference, midarm circumference, and triceps skinfold thickness), pubertal staging, skeletal maturity staging, and biochemical tests of nutritional status. The use of age, gender, and disease-specific growth charts is essential in assessing nutritional status and monitoring nutrition interventions. Nutrition assessment and dietary counseling is helpful for the cure of disease, and moreover, the prevention of illness.

  • 아동복지시설 7곳의 미취학아동 70명을 대상으로 신체발육과 영양실태를 조사한 결과 다음과 같은 결론을 얻었다. 조사대상 아동들의 신장, 체중 및 멀리둘레는 한국 소아 발육 표준치보다 다소 적었으며 가슴둘레는 거의 비슷한 경향으로 나타났다. 따라서 이들의 체격발달이 일반 한국 소아의 발육에 비해 다소 떨어짐을 알 수 있다. 또한 식이섭취조사결과 한국인 영양 권장량에 비해 모든 아동들에게서 칼슘의 섭취량이, 또 일부 아동에게서 열량, 철분, 비타민 $B_2$의 섭취량이 다소 낮아서 이들 영양소의 섭취를 보충해야 할 것으로 판단된다. 조사대상 아동들의 생화학적 검사결과 철분 결핍 팔현율은 hemoglobin으로 판정시에는 12.9%, hematocrit으로 판정시에는 18.6%이엇으며 혈청 철분 정상 판정기준 미만인 아동들은 총 인원이 4.3%에 해당하였다. 혈청 총 단백은 정상인 것으로 판명되었다. 따라서 영양상태가 취약한 아동복지시설에서의 영양관리가 효율적으로 이루어지기 위해서는 영양관리 담당 전문인력의 확보 및 여러 사회기관에서의 급식비에 대한 보조지원으로 아동들이 충분히 영양섭취를 할 수 있는 적극적인 지원이 있어야 할 것으로 사료된다.

  • Underweight patients were studied with respect to changes in their nutritional status before and after administration of nutritional beverage. Patients with renal hepatic or endocrine disease gastrectomy malabsorption and weight gain over past 6 months were excluded. Ten patients were participated as controls and were allowed to eat ad libitu, Twenty patients were served as case and were administered in addition to their usual diet 400ml of nutritio-nal beverage(Greenbia) high in calorie and protein for 8 weeks. In the beginning of the study most underweight patients showed depressed nutritional status in terms of calorie intake quality of protein intake and the levels of visceral protein status and serum micronut-rients. The controls consumed less amounts of calories proteins vitamins and minerals while those given the nutritional beverage exceeded their estimated energy requirement(105%) and consumed a mean of 96g protein per day. Those given nutritional beverage for 8 weeks showed significant increase in body weight(3%) hemoglobin(3.2%) hematocrit(5.4%) serum transferrin(19.4%) iron(30.1%) and zinc(20.9%) In the controls however significant improvement was not observed in any parameters compared with initial values. significant improvement was not observed in any parameters compared with initial values. This study suggests that patients with underweight can show mild nutritional deprivation nutritional support can improve their unbalanced status and prevent severe malnutrition.

  • Anemia in women during pregnancy and after delivery has been known to affect the mother, the fetus, and the infant's growth and health status. Studies examining, changes in iron and folate status associated with anemia during pregnancy and during pregnancy, and those supplements are stopped after postpartum. However, the effects of those have not been clearly determined in pregnant and lactating Korea women. Therefore, this study was performed to determine the changes in maternal iron and folate status during pregnancy and six months after delivery longitudinally in six pregnant women who consumed supplements from 20 wk to delivery. We concluded that the iron status deteriorated during pregnancy and especially was weak in the third trimester, but had a tendency to recovery after delivery. On the other hand, the folate status deteriorated in the first and second trimester and was good in the third trimester, but had a tendency to decrease after delivery. These results suggested that the iron status was not improved despite consuming total iron supplements of 50 mg/day through diets and supplements during the second half of the pregnancy. On the other hand, the folate status improved at the end of pregnancy by consuming folate supplements of a total of 800 mg/day through diets and supplements. However, folate status was poor in the first half of the pregnancy, and the tendency of folate status to decrease during postpartum was advanced. At the point in which iron and therefore supplementation is essential. However, the effects of supplement intake time and intake dosage need to be verified and the nutritional status changes of postpartum women should be carefully monitored.

  • This study investigated the effects of dietary phyate reduction on the apparent absorption and biochemical parameters of iron status in young Korean women. Fourteen healthy, young women consumed low and high phytate diets for ten days of each experimental period. Duplicate diet samples, a fasting blood sample on day 9, and complete fecal samples for five consecutive days starting from day 5 of each diet period were collected. The iron content of diet and fecal samples were analyzed to calculate apparent absorption. Serum samples were analyzed for iron, ferritin, transferrin receptor and TIBC; transferrin saturation was also calculated. The apparent absorption of iron tended to increase in the low phytate period (32.51%) compared to the high phytate period (17.91%), but the difference was not significant (p=0.06). Serum ferritin decreased and serum transferrin receptor increased significantly during the low phytate diet although the mean values were within the normal range. Serum iron and transferrin saturation did not change significantly. In conclusion, the results indicated that reducing dietary phytate for ten days negatively affected iron nutritional parameters, but it moderately and positively affected apparent iron absorption in young Korean women. Further research on the long-term effects of a low phytate diet with an adequate iron content for vows Korean women is necessary.

  • This study was designed to assess the iron nutritional status and growth development of children provided with and without the national school -lunch program(NLSP). The subjects consisted of 590 elementary school children (313 boys, 277 girls) in the 2nd, 4th and 6th grades provided with (n=390) and without (n=200) NSLP. anthropometric measurements were taken for body weight, height, triceps skinfold thickness and body fat percentage. Nutrient intakes were assessed by a modified 24 -hour recall method. Fastinig blood samples were obtained and analyzed for hemoglobin concentration, hematocrit, serum iron and total iron binding capacity. The results obtained are summarized as follows. No significant differences between children provided with and without NSLP were found in height and body weight, but triceps skinfold thickness and body fat(%) were significantly higher in children without NSLP than in those with NSLP. There was no significant difference in hemoglobin concentration and hematocrit between children provided with and without NSLP. However, serum iron concentration and transferrin saturation were higher in the children provided with NSLP(81.9$\mu\textrm{g}$/dl and 22.8%) than in the children without NSLP(73.1$\mu\textrm{g}$/dl and 20.9%). When comparing iron and vitamin C intakes , iron intake was significantly higher in children provided with school-lunch, but vitamin C intake was significantly higher in children provided without school-lunch. Percentages of iron -deficient anemia in underweight, normal and obese children when judged by total iron binding capacity were 14.9%, 12.5% and 25.8% respectively.

  • This study was conducted to assess anthropemrtric, health status, nutritional status, and their correlations in 120 female college students in Kyunggido area. The questionnaires on general living habits, food habits and energy expenditure were used, and nutrient intakes were estimated by Convenience Method. Anthropometric measurement, blood pressure, hemoglobin(Hb), hematocrit(Hct) were also determined. The mean values for BMI, RBW, and blood pressure of the subjects were 20.4$\pm$2.4, 92.9$\pm$16.0% and 108.9/69.6mmHg, respectively. Estimation of body fat from two sites of skinfolds thickness(20.6$\pm$6.0%) and four sites of skinfolds thickness(20.1 $\pm$8.6%) was similar, but different from BIA method(23.9$\pm$3.9%). The subjects of 36.9% considered themselves healthy, and 15.4% of them considered themselves not healthy. The mean values for Hb and Hct were 13.4$\pm$ 1.6g/dl, and 41.5$\pm$0.4%, respectively. The prevalence rates of iron deficiency assessed by Hb and Hct were found to be 19.8% and 6.3%, accordingly. The mean energy intake of subjects was 1,841 kcal. The proportion of energy derived from carbohydrates, protein and fat was 64.9%, 14.7%, and 20.4%, respectively As nutrient intake was compared to RDA for Koreans, intakes of energy, calcium, iron, and vitamin A fell short of recommendations. Intakes of energy, fat, iron, vitamin B$_2$, and niacin were positively correlated with total energy expenditure. These results suggest that appropriate reference data are important to maintain the health of female college students.

  • 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.

  • This study was performed to investigate the effect of dietary iron intake on the immune status of male college students. Twenty healthy male university students participated in the study. The mean age of the subjects was 22.6 years old, mean height was 173.3 cm and mean body weight was 68.4 kg. The mean daily iron intake of the subjects was 19.9 mg, 158.1% of the Korean recommended dietary allowances (RDA). The blood iron status and immune responses of the subjects were analyzed and compared between the high dietary iron group consuming more than 100% of the RDA of iron (Hi-Fe) and the low dietary iron group consuming less than 100% of the RDA of iron (Low-Fe). The serum iron concentration and percent saturation of transferrin were within the normal range in both groups. However, the Hi-fe group had higher serum iron and percent saturation of transferrin than the Low-fe group (p<0.05). When differential white blood cell counts were compared, the Low-Fe group had a lower percentage of neutrophils than the Hi-Fe group (p <0.1). The plasma IL-2 concentration, immunoglobulin levels and lymphocyte subsets were not affected significantly by the differences in iron intake as shown in this study. Serum iron had a positive correlation with monocyte percentage but had a negative correlation with IgM concentration. The results of this study suggest that slightly-low dietary iron intake without anemia has no effects on the cell-mediated and humoral immunities of healthy male university students. However, natural defenses, such as neutrophils and monocytes, seem to be more sensitively affected by changes in dietary iron intake.
