This study compared the nutrient intake of obese versus non-obese non-insulin dependent diabetes mellitus (NIDDM) patients for Diabetes Medical Nutrition Therapy. The study was conducted at medical hospitals in Gyeonggi and Seoul from April 2009 to November 2009. Fifty-six adult male NIDDM patients were enrolled and divided into two groups: 36 into an obese group (BMI ${\geq}25$) and 20 into a non-obese group (BMI<25). To conduct this study, anthropometric measurements, and daily nutrient intake of obese and non-obese NIDDM patients were measured. Daily nutrient intake was estimated by 24hr-recall and analyzed by the CAN program. In the results, anthropometric measurements of the two groups showed significant differences in weight and BMI (p<0.001). Daily nutrient intake of the two groups showed no significant differences, except for vitamin E intake (p<0.05). The total energy intake of the non-obese and obese groups were $2,669.9{\pm}964$ kcal and $2,555.4{\pm}803$ kcal, respectively, which were both above 113% of the recommended Dietary Reference Intakes for Korean (KDRIs). Cholesterol and sodium intake were $378.1{\pm}215.6$ mg and $6,478.9{\pm}2755.1$ mg, respectively for the non-obese group. Cholesterol and sodium intake were $308.1{\pm}155.6$ mg and $6,306.8{\pm}2788.9$ mg, respectively, for the obese group. Both groups were above 150% of the recommended levels set by the Korean Diabetes Association (KDA). However, their antioxidant nutrient intake was appropriate. Meanwhile, their fiber intake was $10.7{\pm}5.1$ g and $9.8{\pm}5.2$ g, respectively, which was lower than 40% of the recommended intake set by the KDA. The results show that the nutritional education for obese and non-obese NIDDM male patients must aim to reduce total energy, cholesterol, and sodium intake, while increasing fiber intake. In addition, the factors related to a patient's glycosylated hemoglobin, serum lipids, blood pressure, and weight change must be calibrated for the appropriate energy, fat, cholesterol, sodium, and dietary fiber intake.

The purpose of this study was to evaluate effects of a nutrition education focused on Food Exchange System for the higher grades elementary children. Nutrition education lessons (40 min/lesson, 4 times), '5 major nutrients and functions', '6 food groups', 'daily needed energy and food exchange units', 'good choice of snacks and balanced exercise' were provided to elementary students (5th grade students). This research was based on the data from two groups of elementary school children in the 'education' group (n = 31) and 'non-education' group (n = 31). We assessed the changes in dietary attitude, food habit and nutrition knowledge using questionnaire and nutrient intake using 24hr recall method by nutrition education using the developed pamphlet. After education, there was a significant difference in the dietary attitude score only in attitude of 'balanced meal' (p < 0.001) in the education group compared to the non-education group. In food habit, there were significant positive changes in the type of breakfast and in the priority of choosing snack in the educated group. In nutrition knowledge, there were significant increases in scores of 'function of carbohydrate' (p < 0.05), 'function of fat' (p < 0.01), 'function of vitamin' (p < 0.01), 'foods of carbohydrate' (p < 0.01), and 'foods of vitamin' (p < 0.01) in the educated group. After education, carbohydrate: protein: fat (CPF) ratio was significantly different between the two groups (education group, 59 : 16 : 26 vs. non-education group, 63 : 15 : 23). In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), there were significant positive effects in energy (p < 0.05), thiamin (p < 0.05), riboflavin (p < 0.05), vitamin C (p < 0.05), phosphorus (p < 0.01), Fe (p < 0.01) and zinc (p < 0.01) in the education group compared to the non-education group. In conclusion, the developed 4 times' nutritional education pamphlet focused on individual daily energy requirements and food exchange units using food exchange system for higher grades' elementary student may positively change nutrition knowledge and dietary intakes.

The purpose of this study was to investigate the effects of nutrition education using Food Exchange System on elementary students' nutrition knowledge, dietary attitude and nutrients intake. Nutrition education lessons (40 min /lesson, 4 times), '5 major nutrients and functions', '6 food groups and sources of 6 food groups', 'good choice of snacks and eating out' as class lesson, 'daily needed energy and food exchange units' as individual lesson, were provided to 70 elementary students (4th grade 33 students, 5th grade 37 students) in Jeonbuk Province. We assessed the changes in nutrition knowledge, dietary attitude, food habit using a questionnaire and nutrient intake using 24 hr recall method by nutrition education. In nutrition knowledge, there were significant increases in scores of 'functions of carbohydrate', 'functions of protein', 'functions of lipid', 'foods of carbohydrate', and 'foods of lipid'. In dietary attitude, there were significant increases in scores of 'taking a meal with joy', 'taking a meal at ease', 'taking a meal with sufficient protein intake' and 'taking a meal without spicy foods' by nutrition education. There were significant changes in the type of breakfast and in the frequency of snacks. After education, in type of breakfast, it showed higher number of students ate rice oriented meal than they did before education. and in frequency of snacks, it showed lower number of students ate snacks 'over 3 times' than they did before education. In Carbohydrate : Protein : Fat (CPF) ratio (%), it was significantly changed from 55.8 : 17.7 : 26.6 to 63.6 : 15.3 : 21.1. In evaluation of nutrient intake by Dietary Reference Intakes for Koreans (KDRIs), vitamin A, thiamin, niacin, vitamin $B_6$, calcium, phosphate, iron and zinc showed positive changes in distribution of number of children by intake level. That is, there were significant improvements in intakes of vitamin A, thiamin, niacin, vitamin $B_6$, calcium, phosphate, iron and zinc. These results showed that nutrition education using Food Exchange System for elementary students improved nutrition knowledge, dietary attitude and nutrients intake. It suggest that nutrition education using Food Exchange System may improve dietary behaviors and reduce an incidence of obesity in elementary students.

The purpose of this study was to investigate the status of magnesium, iron, copper and zinc nutrition in 28 normal and 28 obese male elementary school students who have over 30% obesity index. The anthropometric measurements, dietary intakes and serum levels of magnesium, iron, copper and zinc were determined by 24-hr recall method and blood analysis, respectively. The mean age, height, weight, and obesity index were 10.9years, 147.4cm, 61.1kg, and 50.5% in obese group and 10.8years, 145.4cm, 40.2kg, and 3.3% in normal group. There was no significant difference in average daily food intake between obese and normal group, but meats(p＜0.05) intake of obese group was significantly lower than that of normal group. The intakes of energy, magnesium, iron, copper were not significantly difference between obese and normal group, but heme iron(p＜0.05) intake of obese group was significantly lower than that of normal group. Zinc(p＜0.05) intake of obese group was significantly higher than that of normal group. Serum magnesium(p＜0.001) level of obese group was significantly higher than that of normal group, but there were no significant differences in serum iron, copper, zinc levels between obese and normal group. There was a significantly positive correlation between serum magnesium and weight(p＜0.05), and obesity index(p＜0.05). There was a significantly positive correlation between serum magnesium and energy intake(p＜0.05), protein intake(p＜0.05), animal protein intake(p＜0.05), phosphorus intake(p＜0.05) and animal iron intake(p＜0.05). There was a significantly positive correlation between serum magnesium and seaweeds intake(p＜0.05), milks intake(p＜0.001). Also, there was significantly positive correlation between serum copper and oils and fat intake(p＜0.05). These results suggest that there should be careful considerations for micronutrients nutrition status among male obese elementary school students.

This study was performed to investigate the effect of vitamin C and E supplementation on blood pressure, plasma lipids, folate, and homocysteine levels in smokers and non-smokers of college male students in Gyeonggi Area. The nutrient intakes were determined by a 24hr-recall method. The subjects were divided into six groups: vitamin C sup-plementation group (n: smokers = 10, nonsmokers = 10), vitamin E supplementation group (n: smokers = 10, nonsmokers = 10), vitamin C and E supplementation group (n: smokers = 10, nonsmokers = 10), respectively. There were no significant differences between the smokers and nonsmokers in terms of anthropometric measurements. Systolic and diastolic blood pressure were significantly higher (p < 0.05) in smokers than that of non-smokers. There was no significant difference in energy and other nutrients intakes between smokers and non-smokers. In plasma lipids levels, smokers had higher plasma triglyceride, LDL-cholesterol, VLDL-cholesterol, total cholesterol concentration than that of non-smokers (p < 0.05). HDL-cholesterol level of smokers had a tendency to be lower than that of non-smokers. In smokers, AI, TPH, LPH were significantly higher than that of non-smokers (p < 0.01). Plasma folate, homocysteine levels were not significantly different between smokers and non-smokers. The effect of antioxidant vitamins supplementation in smokers: In vitamin C supplementation group, HDL-cholesterol level was significantly in-creased (p < 0.01) and AI, TPH, LPH were significantly decreased (p < 0.01). In vitamin E supplementation group, HDL-cholesterol level was significantly increased (p < 0.05). In vitamin C and E supplementation group, LPH was significantly decreased (p < 0.05). The effect of antioxidant vitamins supplementation in non-smokers: HDL-cholesterol level was significantly increased (p <0.05) and AI, TPH, LPH were significantly decreased (p <0.05) by vitamin C supplementation group. Plasma homocysteine level was decreased by vitamin E supplementation group in non-smokers (p < 0.01). The results of this study showed that smoking had a tendency to increase plasma lipids levels that factor into the risk of coronary heart disease. It is considered that antioxidant vitamin supplementation in smokers had a tendency to decrease cardiovascular disease than in nonsmokers.

The purpose of this study was to determine the iron status of preschool children in Ulsan, Korea. The study was con-ducted using 95 children aged 3 to 6 years by investigating the anthropometric indices and assessing the dietary intakes and biochemical analysis. A questionnaire for dietary intakes using 24-hr recall method were carried out by the mothers of the 95 subjects. And also a study was conducted to assess hematological and biochemical status of iron and prevalence of iron deficiency. The average height and weight were 105.4 $\pm$ 7.0 cm, 18.7 $\pm$ 3.2 kg in boys, 103.8 $\pm$ 6.7 cm, 17.6 $\pm$ 2.7 kg in girls. These were lower than the body growth standard values of Korean pediatrics. There was not a significant difference in both between boys and girls. For the daily nutrient intake, energy was 1201.5 $\pm$ 280.9 kcal (79.3$\%$RDA), protein was 63.8 $\pm$ 28.2 g (219.4$\%$RDA), iron was 11.9 $\pm$ 4.5 mg (133.2$\%$RDA). The iron nutritional status by hematological assay found that Hct was 34.7 $\pm$ 2.0 ($\%$), Hb was 12.0 $\pm$ 0.8 g/dl, RBC was 4.3 $\pm$ 0.3 ($10^6/{\mu}l$), MCV was 80.5 $\pm$ 3.0 fL, MCH was 27.8 $\pm$ 1.1 pg and MCHC was 34.6 $\pm$ 0.6 g/dl. The biochemical measurement of serum iron was 75.6 $\pm$ 30.3 ${\mu}g$/dl, TIBC was 320.3 $\pm$ 34.1 ${\mu}g$/dl, serum ferritin was 30.0 $\pm$ 14.8 ${\mu}g$/dl, Zinc-Protophor-phyrin (ZPP) was 32.7 $\pm$ 8.0 ${\mu}g$/dl, and ZPP/Heme was 71.1 $\pm$ 19.5 ($\mu$mole/mol heme). The prevalence with Hct, Hb, TS and serum ferritin less than cut-off value was $8.4\%,\;9.5\%,\;12.6\%$ and $4.4\%$ respectively. But the prevalence of iron deficiency estimated with ZPP and ZPP/Heme criteria were $25.3\%$ and $27.4\%$, and were higher than in case of any other indices. The prevalence of iron deficiency anemia ((low Hb (< 11.0 g/dl) and low serum ferritin (< 10 ${\mu}g$/L) or low TS (3-4 yews: < $12\%$, 5-6 years: < $14\%$)) was found in only one 3 year old girl. The prevalence of iron deficiency except Hct and Hb was the highest in 3 year group, but the prevalence by Hct and Hb was the highest in 5 year group. Iron deficiency and iron deficiency anemia do not seem to be a major public health problem in preschool children in Ulsan.

The purpose of this study was to investigate the effect of bone mineral density on life styles, dietary habits and nutrient intakes among the male college students. The subjects were divided into four groups; $Q_1$ (calcaneus BMD < 25 percentile, n = 117), $Q_2$ (25 percentile $\le$ calcaneus BMD < 50 percentile, n = 118), $Q_3$ (50 percentile $\le$ calcaneus BMD < 75 percentile, n = 118) $Q_4$ (calcaneus BMD $\ge$ 75 percentile, n = 116). And they were asked about general characteristics, life style, dietary habit, and nutrient intake using questionnaire and 24-hr recall method. They were measured the bone mineral density of calcaneus using quantitative ultrasound. The average age of the subjects of the study was 23.0 yews and the average height, weight, and BMI were 174.7 cm, 69.0 kg, $22.5 kg/m^2$. The bone mineral density in calcaneus was $0.43 g/cm^2$ in $Q_1,\;0.50 g/cm^2$ in $Q_2,\;0.56 g/cm^2$ in $Q_3$, and $0.69 g/cm^2$ in $Q_4$ (p < 0.001). The results showed that $Q_1$ tended to have irregular exercise compared to the other three groups. Compared with $Q_1$ and $Q_2$, the frequency of skipping breakfast was lower in $Q_3$ and $Q_4$. Also the results showed that the $Q_4$ was significantly more often to drink coffee compared with the other three groups (p < 0.01). The mean daily energy intake was 2210.6 kcal ($88.4\%$ of RDA). The intake of energy, vitamin $B_2$, calcium, and zinc did not meet the Korean RDA. Also the $Q_2$consumed significantly lower intakes of protein (p < 0.05) and plant protein (p < 0.05) compared to the $Q_3$ and $Q_4$. The $Q_1$ and $Q_2$ consumed significantly lower intakes of vitamin $B_2$ (p < 0.01) compared to the $Q_3$ and $Q_4$. In conclusion, male student in lower bone mineral density appeared to have unhealthy life styles and dietary habits in terms of irregular exercise, high frequency of skipping breakfast and lower intakes of protein, vitamin $B_2$ showing a strong need proper education on meal practices and exercise habits for the bone health.

단백질과 칼륨의 섭취량으로 산출한 NEAP와 여성의 골밀도 및 골대사지표와의 관련성을 알아보기 위하여 $18\sim81$세의 여성 276명을 대상으로 설문조사와 식사섭취조사, 요추와 대퇴경부의 골밀도 측정, 소변의 디옥시피리디놀린을 분석한 결과는 다음과 같다. 대상자들의 NEAP 수준은 요추 골밀도(p<0.05)와 유의적인 음의 상관성을 보였고 대퇴경부 골밀도와도 유의적인 수준은 아니었으나 음의 상관성을 보였다. NEAP의 수준에 따라 대상자를 4분위수로 분류하고 연령, 신장, 체중의 차이를 보정하여 골밀도를 비교하였을 때 NEAP 수준이 가장 낮은 군의 요추 및 대퇴경부 골밀도가 가장 높았으나 유의적인 차이를 보이지는 않았다. 또한 단백질의 섭취량에 따른 골밀도의 4분위수 분석결과 단백질의 섭취량이 증가함에 따라 요추 골밀도가 감소하였다(p<0.05). 이상의 연구결과를 통하여 체내에서 알칼리를 생성하는 칼륨의 섭취증가와 체내에서 산을 생성하는 단백질의 섭취감소를 통한 체내 산도의 감소가 여성의 골밀도와 긍정적인 관련성을 나타낼 수 있음이 제시되었다. 따라서 칼슘섭취의 부족문제가 좀처럼 해결되고 있지 않은 우리나라의 식생활에서 골용해와 칼슘의 배설을 줄임으로써 골격건강을 유지할 수 있는 방안으로 단백질의 과잉섭취를 제한하고 체내 알칼리를 형성할 수 있는 무기질이 풍부한 식품의 섭취를 늘일 수 있도록 하는 식사지침의 마련이 필요하다고 생각된다. 또한 본 연구에서는 골밀도에 긍정적인 영향을 미치는 체내 알칼리성 유도 영양소를 칼륨으로만 한정했지만, 마그네슘이나 칼슘 등도 체내 알칼리성에 영향을 미치는 요인이기 때문에 다양한 알칼리성 영양소의 섭취가 골밀도에 미치는 영향에 대한 추후 연구가 요구된다.
