To assess the food habits, nutrient intake and diet quality of preschool children aged 1 to 6 in Pusan by their meals and snacks, dietary survey was conducted with 176 subjects by a questionnaire and 24hr recall method. 63.1% of the subjects often skipped meals and 72.1% of those skipped breakfast in the main. 94.5% had snacks over once per day. The mean energy intake was 1406.4kcal, with 57.7% of energy intake being supplied by carbohydrate, 13.7% by protein, 28.6% by fat. 54.9%, 71.7% and 26.5% of intakes of protein, calcium and iron were supplied respectively by animal food. Most of iron intake came from plant origin. The percent of calcium intake from animal origin was low significantly in a group aged 4 to 6(p<0.05). The mean intakes of calcium, iron and niacin of total subjects were below Recommended Dietary Allo wance(RDA) for Koreans. The mean intakes of iron and niacin of a group aged 1 to 3 were below RDA as well as those of energy, caicium, vitamin B2 and niacin of the group aged 4 to 6. For calcium, iron, vitamin A, niacin and vitamin C, proportions of subjects with intake levels less than 75% of RDA were all over 36%. For most nutrients, proportions of subjects with intake levels less than 75% of RDA were higher in the group aged 4 to 6 than in the group aged 1 to 3. Nutrient adequacy ratios(NAR) were the lowest in iron in case of the group aged 1 to 3 and in calcium in case of the group aged 4 to 6. NAR of iron increased and that of vitamin B2 decreased significantly along increase age(p<0.05). The mean adequacy ratios(MAR) were 0.82 for total subjects, 0.83 for the group aged 1 to 3 and 0.80 for the group aged 4 to 6. The indexes of nutritional quality(INQ) of calcium, iron and niacin of the group aged 1 to 3 were below 1 as well as those of calcium, vitamin B2 and niacin of the group aged 4 to 6. Both of the age groups received 31.6~59.0% of daily intakes of energy, fat, calcium, phosphrous, vitamin B2 and vitamin C from snacks. So snacks clearly play an important role in dietary intake. Both of the NARs of most nutrients and MAR were higher in snacks than in three meals. The INQs of calcium and iron from three meals and those of iron, vitamin A, vitamin B1 and niacin from snacks of the group aged 1 to 3 were all below 1. The INQs of calcium and vitamin B2 from three meals and those of vitamin A and niacin from snacks of the group aged 4 to 6 were all below 1. In conclusion, nutritional characteristics were different between the two age groups. More attention should be paid to improve adequacy of nutrient intake through meals. And dietary management for snacks is needed especially in the group aged 1 to 3.

The purpose of this study was to compare the consciousness of health status and nutrient intake of farmers in Korea. Eight hundred were surveyed by rural leaders of Rural Development Administration(RDA), composed of 35.1 % male and 64.9% female. Data collection included personal & family situation by Interview method for influencial factors of health status. Food intake was determined by semiquantitative food frequency method with 65 kinds of foods. 32.5% of the subjects were elementary school graduates, younger age groups and males had higher levels of education. Mean family numbers was 4.2 persons. In the concept of disease prevalence, gender difference existed. Liver and heart ailments were frequent in males and waist pain and urinary complaints in females, and schoulder pain and nervesness were frequently prevalent to all farmers. The energy intake of farmers was 2000Kca1/day, 19:16:65 of PFC(protein, fat, and carbohydrate) ratio was approached at recommended composition of energy. But calcium and iron were lower than Korean Recommended Dietary Allowences(KRDA), Vitamin A, thiamin, niacin, and vitamin C were over of KRDA, but riboflavin, pyridoxin, and vitamin I were lower than KRDA. The nutrient intakes of poor health groups were significantly lower than those of healthy. In fatty acid composition, monounsaturated fatty acids(FA) intake was higher than that of saturated FA. The CMI (Cornell Medical Index) and Farmers' syndrome were significantly correlated with personal factors, such as height, number in family, education level, and working level. But the correlation of health status with nutrient intakes were only weakly significant. Depending on the regression analysis, Farmers' syndrome explanation about nutrient intake was low(R2 was only 0.01 more or less), but some nutrients (energy, niacin, pyridoxine, vitamin E, and lipids) could explain this significantly. It was concluded that body complaints of farmers could ameliorate with good nutrition.

The purpose of this study was to investigate the effects of dietary behavior on the nutritional status of university students in Korea. A dietary intake survey of 603 university students (223 males and 380 females) was conducted using a 24-hour recall method. The resulting data on dietary behavior and nutrient intakes were analyzed by the SAS program package. The main results were as follows : 1) Most of the subjects were in their twenties and no obese cases were found. 2) Dietary intake data showed that, except for vitamin C in the female students, the average daily intakes of most nutrients did lot meet the Korean Recommended Dietary Allowances (RDA). The study also showed that most of the subjects, especially the female students, were concerned about having satisfactory physical appearances. Fat provided 25% of the daily energy intake, and this level was higher than the 20% recommended by the Korean Dietary Guidelines. In the female students, the iron intake from animal foods was lower than that from plant foods. 3) Male students were not very serious about healthy eating. However, the female group, who obtained a high score in dietary behavior, consumed more vegetables and had higher intakes of energy, protein, Ca, p, vitamin A, and vitamin C than the male group, even though they did not meet the Korean RDA in most nutrients. Energy intake from fats, as a percent of total energy intake, was lower than in the group of females who obtained higher stores in dietary behavior than the other groups. To sum up, the university students surveyed in this study were found to have the typical dietary behavior of young adults, such as frequent eating out and snacking. Female students were extremely conscious of their body images this can exert an important direct influence on their dietary intakes and health status. It is very important for university students to develop healthy lifestyles and desirable dietary behaviors, to best enable them to continue to lead a healthy lift: in their later years.

Purpose: The purpose of this study was to explore the perimenstrual discomforts and dietary intake levels among normal women. Method: A prospective and descriptive study examined 38 women aged 23 46years of age. The data collection period lasted from April 1 to June 30, 2003. The participants were asked to keep a diary recording perimenstrual symptoms and food intake for 50 days. Results: There was a significant difference in physical symptoms of perimenstrual discomforts (F=6.95. p=.001). but there was no significant difference in dietary intake level according to three different phases of a menstrual cycle. The significant dietary intake variables correlated to PMS included energy, protein, Vitamin E, Vitamin $B_2$, niacin, Vitamin $B_6$, folic acid, phosphorus, iron, and zinc. They were negatively related to perimenstrual discomforts. Conclusion: Balanced diet intake will be necessary for not only the perimenstrual discomforts but also the general health promotion of the entire population. The dietary and nutritional assessment should be done prior to nursing interventions, and nutritional counseling and education should be given based on individual differences. In a further study, the effects of dietary composition on specific symptoms will be replicated with a large sample, and development of a diet intervention program for perimenstrual discomforts is recommended.

This study was carried to investigate the effects of alcohol intake on the dietary behaviors and nutrient intakes of students in university and was observed characteristics of alcohol drinking, smoking, dietary behaviors, and nutrient intakes of students. The mean of alcohol consumption was 25.7$\pm$21.7g/day and 47.5$\pm$25.8g/day, most high of high alcohol group in the male student than other groups. Smoking were high by increasing of alcohol intake. Most students had dietary problems as skipping meals, eating snack after dinner, high frequency of eating fast and instant food, and eating meals at watching TV or video. The dietary behavior problems in the high alcohol groups showed higher in the female students than the male students. Nutritional knowledge scores was no significantly different by sex and alcohol intake. The intakes of calorie, protein, phosphorous, iron, and niacin in the male students was significantly higher than those of female students. Except for calcium, vitamin $B_2$ and vitamin C, nutrients were satisfied to the level of Recommended Dietary Allowances(RDA). Nutrient intakes was not affected by alcohol intake. But intakes of calorie, protein, phosphorous, and iron were affected by sex and vitamin C intake was affected by sex and alcohol intake.

This research was conducted to evaluate the general dietary quality(the balance and diversity of food intake, nutrient intake and adequacy) of 12 to 36-month-old toddler, through examining their actual food intake. It was conducted for 664(male-357, female-307) healthy toddler who were outpatients from Mar. to Aug., 1999 at university hospitals and private hospitals in Seoul and kyunggi province. The anthropometric parameters were measured. The 24-hr recall method were utilized to analyze the nutrient intake by months, based on the classification of The Korea Child Gorwth Standard. As for the subjects of this research, we found that the younger the age, the more frequent the pattern of intake of only 3 kinds of food groups. The results are that 1) the group with 1 point of the DDS(Dietary Diversity Score) mostly took only foods from the milk group, 2) the group with 2 points only took foods from the grain and milk group, 3) the group with 3 points did not take foods from the fruit and vegetable group, and 4) the group with 4 points took just about all kinds of food groups except for the vegetable group. This means that most of them were not taking various kinds of food even after the age of 12 months, and that they took more than twice the recommended amount of foods from the milk group until the age of 20 months. Thus, one could find a tendency of dependance on the milk group for food intake. Food intake for the vegetable group was severely under the recommended allowance, regardless of the age. The intake of iron was less than two thirds of the recommended allowance, except for the group of 12 to 14-month-olds who had been fed with infant formula. The Nutrient Adequacy Ratio(NAR) of major nutrients(protein, calcium, phosphorous, iron, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C) and the Mean Adequacy Ratio(MAR, shows the general quality of dietary intake) was 0.86$\pm$0.12, but the NAR of iron was 0.62$\pm$0.27, which was extremely low compared to those of other nutrients. Therefore, concerning the subjects of this research, the MAR value alone does not provide enough ground to conclude that the subjects dietary quality is satisfactory.

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.

Infants and children with food related Atopic Dermatitis (AD) need extra dietary efforts to maintain optimal nutrition due to food restriction to prevent allergy reactions. However, nutrition ignorance and food faddism make patients even more confused and practice desirable diet more difficult. The objective of this study was to report the AD patients' malnutrition cases in Korea. We report on 2 cases of severe nutritional deficiency caused by consuming macrobiotic diets which avoid processed foods and most animal foods, i.e. one of vegetarian diet. Case 1, a 12-month-old male child, was admitted with severe marasmus. Because of a history of AD, he was started on mixed grain porridge at 3 months without any breast milk or formula feeding. His caloric intake was 66% and protein intake was 69% of the recommended dietary allowance. Patient's height and weight was under 3th percentile. On admission the patient was unable to crawl or roll over. Case 2, a 9-month-old AD female patient, was diagnosed with kwashiorkor and rickets. She was also started on mixed grain porridge at 100 days due to AD. Her caloric intake has been satisfied recommended dietary allowance until 7 months, however, she conducted sauna bath therapy and reduced both energy and protein intake at 8 months. The amount of protein intake for case 2 was higher than recommended dietary allowance, but, sauna therapy and severe AD with intakes of low guality protein may increase patient's protein requirement resulting in kwashiorkor. Case 2 patient's height and weight was on 3th percentile. Both cases showed low intake of calcium, iron, zinc, vitamin A, vitamin E and especially very low intake of vitamin B$_{12}$ and vitamin D. Allergy tests for certain foods had not done prior to admission for both cases. They followed the dietary advise operated by macrobiotic diet internet site. In conclusion, AD infants' parents and caregivers should contact a pediatrician trained as a specialist in allergy for accurate diagnosis. For infant patients, breast or formula feeding including hypoallergenic formula should be continued until their one year of age. When certain foods need to be restricted or to follow special diets such as vegetarian diet, consultation with pediatrician and dietitian is needed.d.
