This was a clinical trial study to aid the recovery of elderly female alcoholic liver disease patients by providing a balanced nutritional supplement comprising soymilk. All patients gave their consent before enrolling. The average demographics of the subjects were age 81.57 years, height 150.43 cm, weight 52.67 kg, and body mass index 24.15 kg/m². An increase in the daily consumption of fruits and fruit juice was observed after the patients had started taking the balanced meal as compared to before. Intakes of vitamin A, vitamin C, vitamin E, and cholesterol decreased after consuming soymilk, whereas vitamin B₁₂, niacin, folic acid, and dietary fiber significantly increased (P<0.05). Blood cholesterol and BUN levels showed a decreasing tendency. Our results indicate that consuming soymilk in a balanced diet for female patients afflicted with alcoholic liver disease helps improve their nutritional status by increasing the nutrients lacking in the body.

This study was performed to investigate the factors related to vitamin & mineral supplement use by the adolescents. Nine hundred and seventy-two adolescent boys and girls attending middle or high schools were chosen from various cities and rural communities in Korea. In this study, the factors affecting vitamin & mineral supplement use were analyzed from a self-administered questionnaire. It was found that vitamin & mineral supplements were taken by 31.3% of subjects. High school students(p<.01), female girl students(p<.001), and rural-dwellers(p<.001) took vitamin & mineral supplements more frequently than their complementing groups. The socioeconomic status of the family (p<.01), and supplement consumption by parents and siblings respectively affected the supplement use by the subjects(p<.001). Vitamin·mineral supplements were consumed more often in subjects who perceived their health as poor(p<.001), skipped breakfast(p<.05), and received nutritional information from books or magazines(p<.05). However, food habits and nutritional knowledge score of subjects did not affect vitamin & mineral supplement use. These findings suggest that adolescents take vitamin & mineral supplements commonly, and they tend to use supplements without prescription. Vitamin·mineral supplement consumption seems to be affected by general characteristics, health related variables, and meal management attitudes of subjects. Therefore, nutritional understanding and education are required in regard to the used of vitamin & mineral supplements, and the relationship between balanced diet and good health for the adolescents.

The purpose of this study was to investigate of the dietary life and nutritional status of the Buddhist priests. Dietary life, the state of prepare a meal and menu are carried out through the questionnaire and the nutritional status is carried out through the analysis of the constituents of the blood. The results of this study can be summarized as follows. 1. The traditional temple's foods undergo a change with the variety and westernization of dietary life. 2. Buddhist priests take a carbohydrate centered meal and the intake of protein and lipid is tendency to lack, but the intake of vitamin and mineral is sufficient with various vegetables. 3. The content of the lipid compoents and glucose of blood are low and they are free from the danger of geriatric diseases but the content of triglyceride is very higher than the healthy general adults. Therefore it is necessary to improve the nutritional status of the buddhist priests with decrease the intake of rice and increase the various side dish and to develop the standard menu for the Buddhist priests.

This study was performed to investigate the effect of family type on the nutrient intake and nutritional status in elderly women. Blood samples and anthropometric data of elderly women aged from 60 to 78 years were collected in 1996, who visited a health examination center in Seoul to screen their health status. They were divided into two groups by their family type, one was extended family(extended family elderly, n=37) and the other was independently living(independently living, n=29). Nutrients intake was measured by interview using a simplified questionaire. Albumin, cholesterol, triglyceride(TG), hemoglobin (Hb), hematocrit, Ca, Mg, and alkaline phosphatase activity of serum were analyzed. Intakes of energy, protein, carbohydrate, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were not different between the two groups. However, fat and Ca intakes were higher(p<0.05) in extended family elderly than indepen dently living elderly. There are no significant difference in hematocrit value and serum concentrations of Hb, TG, and Ca. Serum Mg and cholesterol levels tended to be higher in extended family elderly. However, serum albumin level was lower(p<0.05) in extended family elderly. These results show that the indepen dently living elderly women had intakes of daily energy, fat and Ca compared to the extended family elderly. Therefore, the nutritional education for the independently living elderly will be focused on the health risk resulted from less intakes of Ca and total energy.

This study is concerned with the nutritional status of the packed lunch boxes which are brought by the junior high school students in Capital City of Seoul. Four hundred and eights students of the 8 school districts in Seoul had been randomly selected as subjects. The contained nutrients in the packed lunch were analysed by the Food Composition Table. To observe the influence of home economical status and mother's educational level on the nutrient concents of packed lunches, the chosen subjects were classified into three large groupings, which are upper, middle and low classes respectively. In addition, comparison between the Recommended Daily Allowanced for Korean people-13 to 15 age group-and the contained nutrients in the lunch boxed had been conducted. T-test was applied to clarify the significance of the differences between each group both economical and educational level. 1. The averaged rations between the Recommended Daily Allowances and the contained nutrients in the lunches stand: Calorie 59.7% (566 Cal.) protein 53.1% (18g), animal protein 48.6% (5g), fat 39.8% (5g), calcium 371.% (0.1g), ferret 66.4% (2.9g) Vitamin A 642 1.U. (31.3%), Vitamin $B_1$ 70.2% (0.3mg), Vitamin $B_2$ 41.4% (0.2g), Niacin 77.0%(4mg), Vitamin C 51.9% (13mg). All of the nctrients fall far behind the Recommended Daily, Allowances for 13 to 15 age group. 2. Home economical status brings influence on the kinds of foods which could been. Protein, animal protein, fat, Vitamin $B_2$, Vitamin C showed significance of diffierences between the upper and middle classes. Between the middle and low classes, Protein, animal protein, fat, calcium and Vitamin C showed significance of difference. And finally, between the upper and low classes, protein, fat, calcium, ferret, Vitamin $B_2$ and Vitamin C showed a great significance. 3. Regardless to the living conditions of the subject students, all the nutrients of the lunches packed by the mothers in the entire educational levels did not reach the Recommended Daily Allowances. Protein, animal protein, fat, ferret, Vitamin A, and Niacin showed the significance of the differences between the upper and middle classes. On the other hand, calorie, animal protein, fat, Vitamin A and Vitamin C showed the significance between the middle and low classes. Between the upper and the low classes, protein, animal protein, fat, and ferret showed significance. 4. The mairdish-ice of the lunch boxes supplied calorie, protein, Vitamin $B_1$, Vitamin $B_2$ and Niacin which stand at 83.8%, 56.1%, 52.5%, and 54.8% respectivly when compared with the whole nutritional contents. 5. The side-dishes of the packed lunch lack in variety of cooking methods. One interesting fact is that entire subject students are very favorable to the food cooked with every kind of grains.

This study investigated the interactions of bone health with several variables such as outdoor activity hours, nutritional status including habitual intake of calcium andvitamin D status in 72 high school girls aged 16-17 yearsattending day classes or night classes. The subjects consisted of 39 day-class students and 33 night-class students. Dietaty nutrient intakes were estimated using the 24-hour recall method. The daily activities of each subject were assessed using an activity questionnaire. Urinary calcium and creatinine excretion were assayed from subjects' 24-hoururine, while 25-OH-vitamin D[25-(OH)-D] and osteocalcin were measured from the subjects' fasting blood. Intake of energy, iron, vitamin A and vitamin C were worse in the night-class students. There was no significant difference in dietary calcium between the subjects in the different class types. Time spent on outdoor activities was significantly less in subjects attending night classes. Urinary calcium excretion of the night-class subjects was significantly higher than that of the day-class subjects (p<0.05). There was no significant difference in serum 25-(OH)-D level according to class type. Serum osteocalcin for night-class subjects was significantly higher than that for day-class subjects (p<0.01). It appeared that the night-class students had poorer dietary habits as well as fewer outdoor activities. Even though the estimated bone health of both groups of subjects appeared to be normal, the overall nutritional intake and duration of outdoor activities appeared to be important for maintaining bone health and lowering the future risk of osteoporosis.

The study was designed to assess the effect of iron and cereal supplementation on children's iron nutritional status in social welfare institutions. Dietary survey was carried out methods of food weighing and record by interview (n=74). A nutritional intervention study was carried out through supplementing iron supplements and cereal for 4 weeks in 4-12 years old children. Children received daily 40 mg elemental Fe as iron protein succinylate (n=23) and 3.6 mg elemental Fe as 100 g cereal (n=24), respectively. Blood samples were drawn before and after supplementation. Nutrients which children's intake was less than two-thirds of the RDA were vitamin A, vitamin B-1, vitamin B-2, calcium and iron. The mean daily intake of iron was 5.1 mg for male and 4.9 mg for female, and 52.3% for male and 45.4% for female of Korean RDA. The proportion of children with iron depletion assessed by TIBC (> 360 ${\mu}g$/dl) and serum ferritin (< 20 ng/ml) were 56.6% and 58.7%, respectively. The proportion of children with the iron deficient erythropoiesis assessed by serum iron (< 70 ${\mu}g$/dl), Hb (< 12 g/dl), Hct (< 36%) were 76.0%, 58.7%, 64.0%, respectively. After iron supplements treatment, Hb (p<0.001), Hct(p<0.001), serum iron (p<0.001), transferrin saturation (p<0.001) and serum ferritin (p<0.Ol) increase significantly and only TIBC decreased slightly. After cereal supplementation, in anemic children, Hct (p<0.001), serum iron (p<0.001) and transferrin saturation (p<0.001) were significantly increased. The effect of iron supplements and cereal supplementation in children with iron deficient erythropoiesis were more effective to improve the iron nutritional status than children with iron depletion. It was concluded that cereal supplementation program in anemic children was also effective to improve iron nutritional status.

The vitamin $B_{6}$ status of 49 healthy college student (women, aged 20-26 y) was estimated for evaluation of vitamin $B_{6}$ status and the Korean Recommended Dietary Allowance (RDA) for vitamin $B_{6}$. The average daily vitamin $B_{6}$ intake of the subjects was 0.86 $\pm$ 0.289 mg/d or 61.43 $\pm$ 24.10% of Korean RDA. The average ratio of vitamin $B_{6}$ intake to daily protein intake was 0.014 $\pm$ 0.003 mg/g protein. Foods from animal and plaint sources provided 34.25 $\pm$ 18.62% and 65.78 $\pm$ 18.72%, respectively, of total vitamin $B_{6}$. Plasma pyridoxal 5'-phosphate (PLP) concentration was significantly (p<.01 - p<.001) positively correlated to intakes of all other nutrients except vitamin C. However, no significant correlation was found between plasma PLP and nutrient intake. Vitamin $B_{6}$ intake only tended to have a positive correlation with plasma PLP concentration. Plasma total cholesterol was correlated to plasma PLP concentration (p<.05). Plasma PLP had no correlation with levels of glucose, triglyceride, and albumin. These results confirm that the present Korea RDA for vitamin $B_{6}$ of 1.4mg/d based on 0.02 mg/g protein is adequate.

In order to provide basic data for the means to improve food situation and nutritional status of those supported by the National Basic Livelihood Security System (NBLSS), we examined household food insecurity and nutritional status of children under the support of NBLSS. This study included 209 children aged 3-12 years (99 boys and 110 girls) and their caretakers. We measured house food insecurity using Radimer/cornell Scale, children's body sizes and nutrient intake by semi-quantitative food frequency questionnaire, and caretakers' nutritional management skills. Only 9.6％ of the households were in food secured (FS) while 8.1％ were in household food insecured, but without hunger (HFI), 42.1％ were in adult food insecured with hunger (AFI), and 40.2％ were in child hungry (CH). Important predictors of food security were nutritional management skills of the caretakers as well as their education, but neither income nor food expenditure of the households. Mean energy intake of the children was 86.0％ of the Korean Recommended Dietary Allowance (RDA). Intakes of protein, phosphorous, vitamin A and B$_1$ were relatively high ranging from 112.3％ to 124.4％ of the RDAs while those of calcium, iron, niacin, vitamin C were low showing 74.8-83.3％ of the RDAs. Height, weight and weight/height ratio were close to the reference levels. Lower nutrient intakes of children were observed as the households were more food insecured. However, nutrient intakes and body sizes of children did not differ as a function of household socioeconomic status representing by income, food expenditure and caretakers' education. Results of this study suggest the importance of food security and nutritional management skills for the children's nutrient intakes. Concerning this matter, a need for nutrition education in the program for NBLSS was discussed.
