This study was conducted to investigate the relationship among Rohrer index, and nutritional intake and biochemical status. We examined physical status, dietary intakes, serum cholesterol, blood pressure and other biochemical of children in Taejon. Thin survey was carried out in October, 1995. The subjects were 362 children, aged from 6 to 11 years old. The results were summarized as follows. By Rohrer index, 4.5% of the subjects were lean, 70.2% were normal, 17.0% were overweight and 8.6% were obese. Systolic and diastolic blood pressures of the subjects were 111.73 and 69.88mmHg, respectively. The systolic blood pressure of obese subjects(119.93mmHg) was higher than any other groups. Total cholesterol level was 160.87mg/dl, cholesterol levels in each group were not significantly different. Hemoglobin level of total subjects was 13.10mg/dl, especially hemoglobin levels of 11 year-old girls was lower than that of the same aged boys suggesting that the girls should be supplied with more protein, iron and other nutrients. Energy and protein intakes wee 86.6% and 94.5% of RDA, respectively. The nutrients above the RDA were only two, phosphorus and-vitamin C. The intakes of iron, zinc and vitamin A were lower than 50% of the RDA's. The levels of zinc and niacin were highest in obese group than any other groups. The subjects in overweight and obese groups had eaten more calories from snack and less calories from breakfast than other groups. Rohrer index was correlated with cholesterol, systolic blood pressure and creatinine levels.

The purpose of this study was to determine the proportion of 5th grade school children with iron depletion or iron depleted anemia with simultaneously assessing their general nutritional status. The anthropometric measurements, nutrient intake, and biochemical status of iron were measured for 261 school children from 5th grade residing in low income area of Pucheon. The mean height and weight of male were 138.7cm and 33.6kg respectively and were significantly lower than those of female. Mean fat percent, triceps skinfolds thickness and arm circumference were 21.4$\%$, 13.7mm and 22.2cm for female and were significantly higher than 19.1$\%$, 11.4mm, 21.4cm of male respectively. The intake on vitamin A and calcium were 46.4$\%$ and 47.7$\%$ of RDA for male and 36.6$\%$ and 44.9$\%$ for male respectively. The energy intake, carbohydrate, thiamin, niacin, ascorbic acid of male were significantly higher than those of female respectively. The mean daily intake of iron were 7.5mg for male and 7.3mg for female and were not significantly different. The mean biochemical indices of iron nutritional status were not significantly different between male and female expect free erythrocyte protoporphyrin(FEP) and FEP : hemoglobin ratio. The proportion of male assessed by serum iron(<70$\mu\textrm{g}$/㎗), Hb($\%$), FEP(<70$\mu\textrm{g}$/㎗RBC) were 25.4$\%$, 8.4$\%$. 0.8$\%$, 1.8$\%$ respectively and 23.2$\%$, 8.4$\%$, 3.4$\%$, 1.0$\%$ for female respectively.

The purpose of this study was to evaluate the nutritional status and to identify related factors in elderly hemodialysis patients. Sixty-four patients who were registered in Asan Medical Center, Seoul, Korea, participated in the study. The data was collected between September and December, 2003. General characteristics were obtained with the use of an interviewer-administered questionnaire. Anthropometric and biochemical data, 3-day dietary records and dietary habits were also obtained. The results of this study were analyzed with t-test or $X^2$-test using SPSS package program. The percentage of elderly hemodialysis patients who were undergoing mild to severe malnutrition (MN group) and were normal nutrition (NN group) by subjective global assessment (SGA) criteria were 46.9% and 53.1 %, respectively. Appetite (p < 0.05) and dietary cholesterol intakes (p < 0.05) were significantly lower in MN group than the NN group. Body mass index (BMI, p < 0.001), lean body mass (LBM, p < 0.05), triceps skinfold thickness (TSF, p < 0.01), mid ann circumference (MAC, p < 0.01) and mid ann muscle circumference (MAMC, p < 0.05) were also lower in the MN group than the NN group. There were also significant differences in blood urea nitrogen (BUN, p < 0.05), creatinine (p < 0.05), prealbumin (p < 0.001) and C-reactive protein (CRP, p < 0.05). SGA was negatively correlated with serum BUN, creatinine and pre albumin, dry weight, BMI, LBM, total body water, TSF, MAC and MAMC, and positively correlated with age. In stepwise multiple regression analysis, SGA was related to BMI, CRP, age and BUN. In conclusion, almost half of the subjects were in malnourished status and had lower values in anthropometric and biochemical data. Our results suggest that SGA is a simple and adequate method for assessing the nutritional status in elderly hemodialysis patients and adequate dietary guidelines based on individual nutritional status are needed in the patients.

This study was performed to investigate the nutritional status of neurosurgical tube-fed patients. The objective of this study was to improve the nutrition management of tube-fed patients. The current practices of tube feeding and enteral nutrition formula as for 95 patients in the hospital were examined by reviewing patients charts, and interviewing patients, nurses and their family members. The results are summarized as follows ; 57.9% of patients that received the formula showed a decrease in mental status. Among the subjects, 55.7% had nervous system diseases due to old age. Most of the tube-fed patients were hospitalized in the emergency room and while hospitalized, the status of their respiratory organ was abnormal. The method of tube-feeding was by Bolus injection and the type of the tube was a 16Fr size silicone tube. The amount of the injection per day while tube-feeding was on average 1424kcal for men and 1322kcal for women and the calories per day ranged from 1000-1500kcal(50.5%). The injection volume averaged 332.7ml and 45% of patients received more than 300ml per injection. The tube feeding intake rate was 127.9ml/min with 50% of subjects in the range of 50-100ml/min and 10% at 20ml/min. The longer the hospitalization, the older age, coma status, and the higher tube feeding rate, the more decreased were the biochemical parameters.

In this paper, we propose a system for analyzing nutrition status based on hierarchical fuzzy inference approach, where the hierarchical fuzzy approach used to analyze the transition process on the nutritional status from an obesity degree, the previous nutritional status, and the eating pattern with an individual. Moreover we discussed about the selection method of fuzzy membership intervals of the next layer to improve the reliability of inference results in hierarchical fuzzy system, where their intervals are modified by using statistical information of the defuzzified results obtained from the previous layer. To show the effectiveness of this system, we evaluated the nutritional status from the information of anthropometric measurement, biochemical test, and INQ on 113 people over the age of 65, and also analyzed their nutritional status.

The purposes of this study are to evaluate nutritional status and dietary intake of vitamin A in 5th and 6th grade primary school children in Chungbuk. Also the relationships between nutritional status and factors relevant to dietary intake of vitamin A were examined. For the study, total 180 children in urban area of Chongju city(37 boys and 40 girls) and rural area of Eumsong gun(56 boys and 47 girls) were recruited. For the assessment of dietary nutrients intake including vitamin A, 1-day, 24-hr recall method was applied. And serum retinol contents were analyzed by HPLC to diagnose the nutritional status of vitamin A. The average of daily vitamin A intake was 490R.E., 81.8% of RDA. Vitamin A intake of urban was higher than that of rural children(p < 0.001). Of the total dietary vitamin A intake, only 25.8% came from animal retinol, means that children still heavily depend on plant carotenoids as vitamin A floods. The average serum retinol concentration of total 180 children was 37.2$\mu\textrm{g}$/100ml. Serum retinol concentration of urban children was 37.3$\mu\textrm{g}$/100m1, significantly higher than rural children of 35.6$\mu\textrm{g}$/100m1(p < 0.05). According to the biochemical criteria, no one was in critical vitamin A nutritional status. Because of relatively large day-to-day vitamin A intake, 1-day, 24-hr recall method may not be the proper way to assess the usual intake of vitamin A. In conclusion , to diagnose the nutritional status of vitamin A by dietary survey, it is necessary to develop new survey technique which measure the dietary habit of the people.

The purpose of this study was to investigate the effects of a nutrition education and exercise on nutritional status in hemodialysis patients, with regard to quality of life (QoL), and fatigue. The subjects were divided into two groups : an educated (E) group (11 men and 9 women) and a non-educated (NE) group (7 men and 22 women). The educated group received a nutrition education and a regular exercise program for 3 months. Data on anthropometric indices and biochemical parameters were obtained from medical records. Dietary habits and nutrient intake were assessed through questionnaires and three-day food records. QoL (through the SF-36 questionnaire) and fatigue (measured by a visual analogue scale questionnaire) were assessed before and after the interventions. Dietary habit scores regarding food variety and fluid intake control significantly increased (P<0.05) after the nutrition education. Furthermore, the intake of total energy, carbohydrates, Fe, and vitamin A significantly increased (P<0.05). Vitamin C intake also significantly increased (P<0.01). Hb levels decreased whereas TG levels increased in the NE group. BUN levels decreased in the E group. After the nutrition education, QoL aspects, such as feelings of pain and general health, and the total score significantly increased (P<0.05) and the level of fatigue score decreased (P<0.01). The results of this study indicate that nutrition education and exercise for hemodialysis patients provides changes in dietary habit, daily nutrient intake, biochemical parameters, QoL, and the level of fatigue. Therefore, nutrition education and exercise help improve nutritional status and QoL.
