Possible correlations between nutrient intake add health status-as assessed by anthropometric measurements, physical performance and biochemical measurements-were investigated, using 514 healthy young men aged 20 years old who had no apparent health problems. The intakes of nutrients were estimated using a three-day dietary recall method. Height and body weight were measured, and body mass index (BMI) was calculated. Physical performance was tested using sit-ups, push-ups, a loom sprint and a 1,500m run. When compared with the Korean recommended dietary allowances (Korean RDA), the subjects nutrient intakes were adequate except for calcium. The intake of calcium was 516.66$\pm$293.43mg/day, which is 73.80 % of the Korean RDA. The subjects averaged 174.51$\pm$7.07cm in height, 68.17$\pm$9.25 kg in body weight and 22.23$\pm$2.16 in BMI. The associations between nutrient intakes and anthropometric measurements, and between nutrient intakes and physical performance, were weak. The intake of vegetable fat was positively correlated to body weight, whereas the intake of carbohydrate was negatively correlated to BMI. The intake of carbohydrate was positively correlated to the level of performance in the loom sprint, and the intake of vegetable Int was positively correlated to the level of performance of sit-ups. No correlation was found between nutrient intakes and the following biochemical measurements of the blood: the levels of glucose, total protein, total cholesterol, triglyceride, hemoglobin and hematocrit. These results suggest that anthropometric measurements and level of physical performance can be associated with energy nutrient intakes, even in moderately active, well-nourished, young men. No correlation was found between nutrient intake and biochemical measurements, probably because all subjects had a reasonably well-balanced diet.

The prevalence of atopic dermatitis (AD) has increased recently all over the world. Several studies worldwide reported growth retardation associated with AD, but few studies were reported in Korea. Therefore, the objective of this study was to identity the differences in growth and nutrient intakes between Korean children with and without AD. The participants were 71 AD children and age, gender-matched 81 control children aged 10 to 36 months. Demographic information was gathered by questionnaires. Height and weight were measured at clinic and health centers. Height and weight for age, and weight for height were converted as deviation in Z scores using World Health Organization Standard. A 24 hour dietary recall method was performed to estimate nutrient intakes. A higher percentage of AD children had insufficient energy and intakes of calcium, phosphorus, iron, zinc and vitamin B2, defined as intakes lower than 75% of the Dietary Reference Intakes for Korean, compared to the control group (P < 0.001, P < 0.001, P = 0.003, P = 0.001, P = 0.014, P = 0.001, respectively). The percentages of children with height and weight for age Z score below than-1 (stunted) were significantly higher in the AD group (P < 0.001 and P < 0.001, respectively). Multiple food restriction, defined as ${\geq}$ 3 food elimination, was associated with insufficient energy and intakes of calcium, phosphorus, iron, zinc, vitamins A and B2. In conclusion, children with AD need regular nutrient assessment and education about alternative food choices to avoid r food elimination in order to prevent growth retardation or inadequate nutrient intakes. Further longitudinal studies for growth and nutrient intakes should be performed to understand the patterns of growth in children with AD.

This study was conducted to find obesity, biochemical indices and nutrient intakes in type Ⅱ diabetes mellitus with hypertension in Gwangju area. Subjects were divided into two groups based on the status of hypertension. Duration of 139 normotensive type Ⅱ diabetes mellitus was $49.8{\pm}80.2$ months while that of hypertensive type Ⅱ diabetes was $79.7{\pm}95.5$ months. Anthropometric measurement revealed that subjects in both groups were in overweight determined by BMI, though there was no significant difference between two groups. Contrastingly, obesity rate and subscapular fat distribution were a good predictor to identify hypertensive group due to the significant differences between two groups, regardless of sex. Hypertensive type Ⅱ diabetes mellitus is significantly associated with more elevated cholesterol and fasting blood glucose level. Triglyceride level in the hypertensive female was prominent. Significant gender differences were shown in energy, carbohydrate, protein, Ca, Zn, vitamin $B_{6}$ and cholesterol intakes. Nutrient intakes of female normotensive group were higher than those of female hypertensive group except for riboflavin. However, different pattern on nutrient intakes in male was noted. Thus, sex is a great determinant to influence nutrient intakes in subject. Effective nutrition education program targeting type Ⅱ diabetes mellitus, especially hypertensive type Ⅱ diabetes mellitus should be developed and implemented to control blood glucose and lipidemia. It might be suggested to consider the importance different approaches of nutrition education program to both genders.

Purpose of this study was to compare nutrient intakes of disabled children and non-disabled children. Subjects consisted of 86 disabled children from a special education school and 127 non-disabled children from an elementary school in Seoul. Nutrient intakes were assessed by modified 24-hr recall method, with the help of children's parents and teachers. Almost all nutrient intakes (energy, protein, fat, carbohydrates, vitamin B$_1$ and niacin) of children with cerebral palsy were significantly lower than those of other groups. But nutrient intakes per body weight of children with cerebral palsy were not significantly different with those of other groups. There was no significant difference between disabled and non-disabled children in almost % RDA (rate of actual intake to RDA) except of energy %RDA in children with cerebral palsy. NARs (nutrient adequacy ratio) for energy and vitamin B$_1$ of children with cerebral palsy were significantly lower than those of children with autism and mental retardation, and non-disabled children. The proportions of energy, carbohydrate and protein intakes from lunch were significantly higher than those from breakfast and dinner in children with mental retardation and autism. The nutrient intakes of disabled children were different between other groups according to the type of handicap. For example, children with cerebral palsy had the risk of undernutrition. On the other hand, autistic children had the tendency of overnutrition. These results suggest that nutrition educational programs and educational materials for disabled children, their teachers and their parents should be developed considering the type of handicap.

This study was designed to investigate food consumption patterns and nutrient intakes of college students, divided into subgroups of normal weight men (no.=140), normal weight women (no.=101), and underweight women (no.=155) by body mass index. Frequency of food eaten, nutrient intakes from each meal, percentages of RDAs, and nutrient densities were analyzed using 24-hour recall records. It was very interesting in these results as follows. Normal weight men ate on the whole more frequently than other groups. Underweight women had higher intakes of nutrient than did normal weight women. However normal weight women consumed food of greater nutrient density than did other college students. Consequently, it is desirable to suggest nutrient density of food than learn RDAs for adequate diet in nutritional education programs.

The purpose of this study was to investigate children's nutrient intakes by school lunch. Evaluation of nutrient intakes by school lunch for three days was conducted with 86 children in urban and 64 children in rural of Jeonbuk area. The results of this study were as follows. 1) With respect to amounts of provided nutrients in school lunch, CPF (carbohydrate : protein : fat) energy ratio was 48.6 : 19.7 : 31.6 in urban and was 46.7 : 20.5 : 32.7 in rural. Compared to 1/3 RDA (RDA) of children for 10-12 years, folic acid and zinc were provided below 50 % of RDA. Protein, fat, phosphorus, vitamin $B_1$, vitamin $B_2$, niacin, vitamin C and vitamin E were provided above 125 % of RDA. There were no differences in amounts of provided nutrients-except calcium, vitamin A, vitamin $B_6$, folic acid and zinc-between urban and rural. 2) With respect to amounts of nutrient intakes, CPF energy ratio was 51.1 : 17.4 : 31.5 in urban and 47.5 : 19.7 : 32.7 in rural. Compared to RDA, folic and zinc were below 50 % of RDA. Iron and vitamin $B_6$ were below 75 % of RDA. Protein, fat, phosphorus and vitamin E were above 125 % of RDA. There were significant differences in nutrient intakes between urban and rural. The children in rural showed higher levels of nutrient intakes-energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, vitamins and folic acid-compared to those of children in urban. These results suggest that programs are needed for providing adequate nutrient intakes for children in school lunch and for improving nutrient intakes of children in urban.

Nutrient supplements are often used by athletes as ergogenic aids. This study was done to investigate the use of nutrient supplements, nutritional knowledge and nutrient intakes of athletes. Subjects of this survey consisted of 195 national team athletes. The prevalence of nutrient supplement use among all subjects was 30.3%, and the frequency of use, by decreasing order, was weight lifting, taekwondo and badminton athletes. Sport drinks were the type of nutrition supplement used most frequently and vitamin C was the second one. Major reasons for nutrient supplement use were to improve training performance and to recover from fatigue, to supplement fluid and to control weight. The average score of nutritional knowledge was $19.9\pm{2.5}$ for nutrient supplement users, and $19.8\pm{3.6}$ for nutrient supplement nonusers. Intakes of protein, calcium and niacin of the user were higher than those of the nonuser. This information provided by this study can help sport nutritionists identify nutrient supplement most often consumed by national elite athletes and can aid counselors as they guide athletes towards more healthful nutrition practices.

BACKGROUND/OBJECTIVES: The aim of this study was to analyze specific foods influencing absolute nutrient intake and between-person variations of nutrient intake among Korean preschoolers. SUBJECTS/METHODS: This study included 2,766 participants aged 1-5 years in the 2009-2013 Korea National Health and Nutrition Examination Surveys. Dietary data were obtained from a 24-h dietary recall method. Major food sources of absolute nutrient intake were evaluated based on percent contribution of each food. To assess the contribution of specific foods to between-person variations in nutrient intake, stepwise multiple regressions were performed and cumulative $R^2$ was used. RESULTS: White rice and milk were main food sources of energy, protein, carbohydrate, phosphorus, iron, potassium, thiamin, riboflavin, and niacin. The percentage of fat contributed by milk was 21.3% which was the highest, followed by pork, soybean oil, and egg. White rice accounted for 25% and 40% of total variability in total energy and carbohydrate intakes, respectively. About 39% of variation in calcium intake was explained by milk while 40% of variation in phosphorous intake was explained by cheese. The top 10 foods contributing to between-person variations in nutrient intakes were similar with food items that mainly contributed to absolute nutrient intakes. The number of foods explaining 90% of absolute amounts of nutrient intakes varied from 28 for vitamin A to 80 for iron. CONCLUSIONS: This study identified specific foods that contributed to absolute nutrient intakes and between-person variations in nutrient intakes among Korean preschoolers. Our findings can be used to develop dietary assessment tools and establish food-based dietary guidelines for young children.

This study examined within-and between-individual variation in nutrient intakes in order to estimate the degrees of precison in dietary assessment among 59 female volunteers aged 21-23 years. Self-recorded 7-day dietary recalls and records were collected by during a 3 month period. Between the recall and record methods, there were little difference of within-and between-individual variations. Within-to-between individual variation ratios were > 2.0 for most of the nutrients examined, and were higher for niacin, vitamin A and C (>2.5) in the recals and for calcium, iron, vitamin A and C(>3.0) in the records. With 7-day dietary data, observed nutrient intakes were estimated to within 26-107% of the subjects' true(usual) intakes, among those vitamin C and energy showed the highest and lowest values, respectively. Correlation coefficients between observed and true nutrient intakes were 0.73-0.81 for the recalls and 0.68-0.77 for the records. In order to estimate with 20% precision, 12-13 days of dietary study were required for energy, 46 for calcium, 71-72 for vitamin A, and 199-200 for vitamin C. Attenuation factor ranged 0.73-0.81 for the recalls and 0.68-0.77 for the records. This study implies that commonly used 1 or 3 day dietary studies may not be appropriate for assessing individuals' nutrient intakes. Further research focusing on the methodological issues in the assessment of Korean diet are needed for between understanding of the relationship between diet and health in Koreans.

This study was performed to assess gender differences in rates of obesity, dietary behaviors, and nutrient intakes among college students living in Gwangju. Anthropometric measurements showed that the body mass indexes (BMIs) of the males and females were $22.1{\pm}2.6$ and $20.1{\pm}2.4$ respectively. All obesity indices including BMI, relative body weight (RBW), % body fat by bioelectrical impedence analysis (BIA), and waist-hip ratio (WHR) were significantly higher in the males than in the females. Abdominal fat was also found to be higher in the males whereas underweight was prominent in the female students. The dietary behaviors of the males as determined by dietary scores, were poorer than those of the females. Twenty-four hour dietary recalls revealed that most nutrient intakes were adequate, exceptions of vitamin C, Ca, and folate intakes in both sexes and Fe intake in the female students. Ca and folate intakes were below 75% of the KDRI for both genders. In addition, Unbalanced energy ratios of carbohydrate, protein, and fat were noted in both genders. Effective nutrition education programs targeting college students should be developed and implemented to increase Ca and folate consumption. It is suggested that gender-based nutrition education approaches be created due to poor dietary behavior in males and inadequate nutrient intakes in female college students.
