This study was carried out to investigate the dietary behaviors, nutritional status and hematological status of female ballet majors a university. The study was conducted from May 11 to June 20, 2004 by questionnaires, anthropometry and blood analysis and data analyzed by SPSS program. The results are summarized as follows: The body mass index (BMI) and body fat rate of the ballet majors were significantly lower than those of the controls. Eighty-six point four percent of the ballet majors and $58.3\%$ of the controls had weight control experiences. Intakes of the nutrients were lower than those of the Korean recommended dietary allowances (RDAs) , except vitamin C in the ballet majors. Intakes of calories, calcium and iron were lower than those of the RDAs in the controls. Serum triglyceride levels of the ballet majors were significantly lower than that of the controls. HDL-cholesterol concentration was higher in the ballet majors than in the controls. No differences were found in the serum total cholesterol level, hemoglobin level, and hematocrit value between the groups. Total iron binding capacity of the ballet majors was higher than that of the controls. Serum iron level was significantly lower in the ballet majors than in the controls. Nutrition knowledge scores and dietary attitude scores were lower in the ballet majors than in the controls. Self esteem and body-cathexis of the ballet majors were higher than that of the controls. These results indicate that the ballet majors should be given more nutritional education to improve their nutritional status and the dancing Performance.

Many countries such as The Republic of Korea have established their own nutritional standards, collectively termed Nutrient Reference Values (NRVs), and they vary due to the science which was reviewed, the purposes for which they are developed, and issues related to nutrition and food policy in the country. The current effort by the Codex Alimentarius Committee on Nutrition and Foods for Special Dietary Uses (CNFSDU) to update the NRVs that were established following the Helsinki Consultation in 1988 represents an opportunity to develop a set of reference values reflecting current scientific information to be used or adapted by many countries. This paper will focus on possible approaches to selecting or developing reference values which would serve the intended purpose for nutrition labeling to the greatest extent possible. Within the United States, the Food and Drug Administration (U.S. FDA) is currently reviewing regulations on nutrition labeling to better address current health issues, and is expected to enter into a process in the next few months to begin to explore how best to update nutrient Daily Values (DVs), most of which are still based on the Recommended Dietary Allowances (RDAs) of the Food and Nutrition Board, U.S. National Academy of Sciences, last reviewed and revised in 1968. In this presentation, I review the current purposes in the U.S. for nutrition labeling as identified in the 1938 Food, Drug, and Cosmetic Act as amended, the scientific basis for current nutrition labeling regulations in the United States, and the recommendations made by the recent Committee on Use of Dietary Reference Intakes in Nutrition Labeling of the Institute of Medicine (2003) regarding how to use the DRIs in developing new DVs to be used on the label in the United States and Canada. Based on these reviews, I then provide examples of the issues that arise in comparing one approach to another. Much of the discussion focuses on the appropriate role of nutrient labeling within the Nutrition Facts panel, one of the three major public nutrition education tools in the United States (along with MyPyramid and Dietary Guidelines for Americans).

This study was administrated to find the effects of dietary habits and nutrient intakes on the development of cardiovascular disease in the elderly aged over 60. The 40 healthy elderlies(18 males, 22 females) and 40 hospitalized elderlies with the cardiovascular disease(23 males, 17 females) were subjected for the study. Body weight, height, BMI and blood pressure were measured. Also, health behaviors such as exercise, smoking, drinking and dietary habits, frequency of intake lipid food in the past, nutrient intake at the present were assessed by interviews and questionnaire. The results of this study are as follows. 1. Body weight and the BMI were higher in hospitalized male elderlies significantly than those of healthy male elderlies(p<0.05). But the blood pressure wasn't different between two groups. 2. The ratio of male subjects who do regular exercise was significantly higher in healthy group(p<0.01). And significant difference in the extent of stress was found between two female groups(p<0.05). 3. The amount of meal and salty taste showed significant difference between two female groups(p<0.01) but the other dietary habits such as meat preference were not different between healthy and hospitalized elderlies. 4. Compared with healthy male elderlies, hospitalized male elderlies showed significantly higher frequency of intake of fish in the past(p<0.05) and frequency of intake of lipid food such as pork and chicken was also higher in the hospitalized male elderlies, but no significant difference in nutrient intake at the present was found between healthy and hospitalized elderlies. 5. Nutrient intake of elderlies showed in the average daily intake of energy, Ca, vitamin $B_2$were lower than Korean recommended dietary allowances(CRDA). For female subjects, the cholesterol intake was positively correlated with body weight, meats and eggs intake showed positive correlation with body weight and the BMI(p<0.01).

This study was conducted to investigate how body size and weight control experience affect the nutrient intakes and the health status of adolescent females. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done by using a t-test, and ANOVA with the SAS computer program. The average height, weight and BMI of the subjects were 161.2 cm, 53.4 kg, and 20.51 kg/$m^2$ respectively. However, 25.1% of the subjects belonged to the underweight group when we divided the subjects into 3 groups- underweight, normal-weight, overweight-according to their present body size. The average Fe intake of the subjects was less than 50% of the Korean recommended dietary allowances. The dietary intakes of energy and Vit. A were significantly higher in the underweight group than in other groups. However, no significant differences among body size groups were observed in the dietary habit score and the nutritional knowledge score. It also appeared that the dietary habit score and the nutritional knowledge score of the weight control attemptees were worse than those of the non-attemptees. The physical health status of the subjects significantly differed according to weight control experience, and the psychological health status of the subjects differed with present body size. The physical health condition of the weight control attemptees was worse than the non-attemptees. and the psychological health condition of the overweight group was worse than other groups. The results indicated that unnecessary weight control in adolescent females induces unhealthy food behavior which is linked to undesirable health status.

The purpose of this study was to collect basic data on the prevention of and education about diabetes mellitus for the nutritional management of a diabetes mellitus risk group. The study which took place in Kangbukgu, Seoul, involved a diabetes mellitus risk group (DMR $\geq$ 110 mg/dL, 61), of males and females, aged 36 to 68 years, and a group of healthy people as a control group ( < 110 mg/dL, 183), using luting blood sugar (FBS) levels. The proportion of people in the abnormal range was higher in the DMR than that of control group for total cholesterol, high-density lipoproteins-cholesterol (HDL-C), total protein, glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and creatinine. Particularly with respect to serum protein the proportion in the DMR in abnormal range (p < 0.05) was significantly higher than that of the control group. The proportion in the DMR with a family history of disease was significantly higher than that of the control group (p < 0.01). Using body mass index (BMI), waist-hip ratio (WHR) and relative body weight (RBW), the obesity indices in the DMR was higher than that of the control group. Comparing the DMR and the control group with respect to dietary habits, it seems that the DMR had more undesirable dietary habits than the control group. When the intake of each nutrient for the DMR and the control group was compared to the Korean recommended dietary allowances (RDA), the proportion of excess intake and deficient intake in the DMR was higher than that of the control group. The DMR showed a greater undesirable dietary intake pattern as compared to that of the control group, based on the RDA. With respect to the dietary diversity score (DDS) and the mean adequacy ratio (MAR) for quality estimation of the overall flood intake, the DMR showed a feater undesirable pattern than the control group. According to the above results, the DMR tended to have more undesirable eating habits when compared to the control group. Therefore, to provide a more efficient nutritional education program for the DMR we must conduct lurker studies on eating habits, so as to provide systematic nutritional management based on theme differences between the DMR and the control group.

The present study was conducted to assess the status of vitamin C among healthy young adults in relation to serum antioxidant parameters [glutathione (GSH), thiols, and total antioxidant capacity, (TAC)], and oxidative stress markers [malondialdehyde (MDA), and nitrites plus nitrates (NN)]. A prospective study included 200 young adults, and their dietary intake was assessed by using food diaries. Fasting plasma vitamin C, serum levels of GSH, thiols, TAC, MDA, and NN were measured using biochemical assays. It was observed that 38% of the enrolled subjects, n=76, had an adequate dietary intake of vitamin C (ADI group). Meanwhile, 62%, n=124, had a low dietary intake of vitamin C (LDI group) as compared to the recommended dietary allowances. The fasting plasma level of vitamin C was significantly higher in the ADI group as compared to the LDI group. Oxidative stress in the sera of the LDI group was evidenced by depletion of GSH, low thiols levels, impairment of TAC, an elevation of MDA, and increased NN. In the ADI group, positive correlations were found between plasma vitamin C and serum antioxidant parameters (GSH, thiols, and TAC). Meanwhile, the plasma vitamin C was negatively correlated with serum MDA and NN levels. This study reveals a significant increase of oxidative stress status and reduced antioxidant capacity in sera from healthy young adults with low intake of the dietary antioxidant, vitamin C.

The correlation between maternal lipid nutritional status during pregnancy and gestational length was investigated. Subjects consisted of 30 full-term delivery mothers, 30 preterm delivery mothers, and babies of both groups. Dietary fat intake during pregnancy and serum lipid levels in mother and umbilical serum were measured. The mean daily intake levels of fatty acid during pregnancy were lower than the recommended dietary allowances, while $\omega$6/$\omega$3 ratios of dietary fatty acids were acceptable. For preterm delivery mothers, fatty acid intake levels to be lower than those in full-term delivery mothers, especially DHA intake of these two groups was significantly different. During gestation, hyperlipidemia was apparent in the pregnant women. The serum lipid contents of preterm delivery mothers tended to be lower than those of full-term delivery mothers, and umbilical cord serum lipid contents of the preterm delivery group tended to be higher than those of the full-term delivery group. Total cholesterol levels in the umbilical cord serum of preterm babies were significantly higher than those of full-term delivery group. On the other hand, total cholesterol and HDL-cholesterol levels between umbilical cord serum and maternal serum were positively correlated in the preterm delivery group. Concerning, energy and fatty acid intakes were more closely associated with umbilical cord serum lipid levels in full-term babies, but negatively associated in preterm babies. It was concluded that gestational length was related to the dietary intake of fatty acids such as DHA in pregnant women. For better understanding, the ralationship between placental lipid transport mechanisms and gestational length needs to be explored.

This study was intended to investigate the nutritional status between lactating and non- lactating women, especially calcium and iron. The subjects were 84 lactating women and 20 non-lactating women visiting a public health center and hospital in Daegu. Each subject was interviewed to collect the information on dietary intake for 2 consecutive days. Biochemical assessment of iron status and bone mineral density (BMD) measurement were conducted. Dietary intake of carbohydrate, potassium, Vit $B_1,\;B_2$, Vit C were significantly higher in women during lactating period (p<0.05). However, relative intake as expressed by percentage of Korean Recommended Dietary Allowances (RDA) was not significantly different between the two groups. The dietary intake of iron and calcium were 58.8%, 60.4% of Korean RDA respectively in women during lactating period. The current food habit score of these women was significantly higher than that of non-lactating women (p<0.05). When we compared the quality of nutritional status, the Index of nutritional quality (INQ) was significantly higher for vitamin $B_2$, P in lactating women than in non-lactating women (p<0.1). Mean adequacy ratio (MAR) was not significantly different between two groups. Dietary variety score (DVS) was significantly higher in women during the lactating period (p<0.05). There was no significant difference in biomarkers (Hb, Hct, Serum ferritin, Transferrin) related to iron status between the two groups. No significant difference in bone mineral density (BMD) T-score was not observed. However, it appeared that BMD of lactating women was lower than that of non-lactating women.

Purpose: The aim of this study was to evaluate the nutrient content consumed by children and adolescents on home-prepared versus chef-prepared specific carbohydrate diets (SCD) as therapy for inflammatory bowel disease (IBD). Methods: Dietary intake of two cohorts with active IBD initiating the SCD over 12 weeks was assessed. The home-prepared cohort received detailed guidance from dietitians on implementation of the SCD. The chef in the other cohort was knowledgeable in the SCD and prepared meals from a fixed set of recipes. Data from 3-day diet diaries at 4 different time points were collected. US Recommended Daily Allowances (RDA) were calculated for macronutrients, vitamins, and minerals. Results: Eight participants on the homemade SCD and 5 participants on the chef-prepared SCD were included in analysis. Mean % RDA for energy intake was 115% and 87% for homemade and chef-prepared groups (p<0.01). Mean % RDA for protein intake was 337% for homemade SCD and 216% for chef-prepared SCD (p<0.01). The homemade SCD group had higher mean % RDA values for vitamin A and iron, while the chef-prepared SCD group had higher intake of vitamins B1, B2, D, phosphorus and zinc (p<0.01 for all). Conclusion: The SCD implemented homemade versus chef-prepared can result in significantly different intake of nutrients and this may influence efficacy of this dietary therapy. Meal preparation dynamics and the motivation of families who pursue dietary treatment may play an important role on the foods consumed and the outcomes on dietary therapy with the SCD.

To assess the dietary fiber intake of preschool children in Busan and to evaluate the relationship between of the intake of dietary fiber and nutrient intake. Nutrient intake using 24 hour recall, and total dietary fiber (TDF) intake based on tables of TDF of common Korean floods developed by the modified Prosky Method, were estimated for 176 preschool children. The mean daily intakes of TDF, and TDF after adjusting energy intake, were 10.20 g and 7.69 g/1,000 kcal, respectively. The mean daily intakes of TDF for children aged 1-3 and 4-6 years were 9.20 g and 11.08 g, respectively. The range of TDF intake was 1.86 to 22.16 g. The major sources of TDF were cereals (31.0%), vegetables (18.9%) and fruits (11.9%). The TDF intake showed positive correlations with nutrient adequacy ratios (NAR) of iron and Vitamin $B_1$, (p < 0.05, p < 0.05). The TDF intake per 1,000 kcal showed negative correlations with the NARs of protein, calcium, phosphate, iron, Vitamin A, vitamin $B_1$, Vitamin $B_2$, and niacin (p < 0.001, p < 0.001, p < 0.001, p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.001) and with the mean adequacy ratio (MAR, p < 0.001). When children were stratified into quartiles ($Q_1-Q_4$) on the basis of their fiber intake per 1,000 kcal, their NARs for calcium, phosphate, iron, Vitamin A, Vitamin $B_1, Vitamin $B_2$ and niacin (p < 0.05, p < 0.05, p < 0.001, p < 0.05, p < 0.05, p < 0.001, p < 0.001), and their MAR (p < 0.001) were significantly lower in the children with higher fiber intake per 1,000 kcal (the upper quartile). The NARs fur calcium (0.63), iron (0.60), Vitamin A (0.66), Vitamin $B_2$(0.74), niacin (0.64), Vitamin C (0.65) and the MAR (0.74) were lower than 0.75 in the children with fiber intakes of more than 9.25 g per 1,000 local (0,), the highest fiber intake per 1,000 kcal. Based on these results, the mean TDF intake of children was higher than the age (yr)+5g , the minimum recommended level for American children. Meals with a fiber intake of more than 9.25 g per 1,000 local ($Q_4$) could cause a decreased nutritional status for minerals and vitamins. The result of this study could contribute to the establishment of Recommended Dietary Allowances (RDA) for dietary fiber for Korean Preschool children.
