The purpose of this study is to evaluate dietary quality of Korea Antarctic expedition by menu analysis. Basic menu pattern, intake of dish and dish group, DDS (dietary diversity score), daily nutrients supply, and NAR (nutrient adequacy ratio) & MAR (mean adequacy ratio) were analyzed using 1 year menu list for the 10th Korea Antarctic expedition. Most frequently served basic menu patterns were ${\ulcorner}$Rice + Soup + 2 Side dish + Kimchi (53.5%)${\lrcorner}$ and ${\ulcorner}$Rice + Stew + 2 Side dish + Kimchi (13.4%)${\lrcorner}$. In the analysis of dish group, excluding Rice and Kimchi, ${\ulcorner}$Grilled foods${\lrcorner}$ and ${\ulcorner}$Pan-fried foods${\lrcorner}$ were served more than 25% per month. Most frequently served dishes were "pan-fried rolled egg", "grilled seaweed", "kimchi soup", "fruits cocktail, canned" and "salt-fermented squid". The kinds of served dishes were very restrictive. The average score of DDS showed 2.88 for summer and 2.97 for winter. Dairy group was almost not served. Fruit & Vegetable groups were also served a little as canned product. The energy ratio of Carbohydrate : Fat : Protein was 56.5 : 23.9 : 19.2, and 56.9 : 24.5 : 18.3, for summer and winter, respectively. Both seasons had higher ratio of carbohydrate and lower ratio of fat compared to the recommended ratio (44 : 40 : 16) in polar area. Ca : P ratio was very poor, 0.40 in both seasons. NAR scores of Ca, vitamin A, vitamin $B_2$ and vitamin C were also very low, ranged from 0.6 to 0.7. Consequently, a well-planned menu supplying adequate amount of dairy, fruit and vegetable is necessarily required including Ca, vitamin D, vitamin A, vitamin $B_2$ and vitamin C intake, and some nutritionally well-educated members are urgently needed to join in the expedition.

The consumption of a wide variety of food groups is considered one of the key components of nutritional adequacy. The 2005 Dietary Guidelines for Koreans includes the consumption of a variety of foods from diverse food groups as a component of a normal diet. A survey was conducted to evaluate the relationship between the dietary diversity of food groups and nutrient intake in elderly patients (age 65 and above) at a rural area in Korea (Inje). 296 subjects (111 male and 185 female) were probed in a 3 day 24-recall dietary survey. Subjects were grouped according to food group intake frequency, based on six food groups (grain, meat/fish/legume/egg, vegetable, fat/oil, dairy, fruit). Nutritional quality was evaluated according to the numbers of nutrients under EAR (Estimated Average Requirements), and MAR (mean adequacy ratios). The frequency of elderly subjects consuming a meat/fish/legumes/egg food group less than once per day was 29.4%. The frequency of elderly subjects consuming fat/oil food group less than once per day was 65.8%. The percentage of subjects who did not eat dairy food was 88.8%, and that of subjects who did not eat fruit was 57.5%. A stepwise multiple regression analysis was used to develop models relating nutritional quality to possible food group intake frequency factors. Using the number of nutrients under EAR as a dependent variable, the meat/fish/legume/egg food group intake frequency explained 9.9% of variance, followed by the grain group, fat/oil group, dairy group, and vegetable and fruit group (Model $R^2$=0.260). For mean nutrient adequacy ratio as a dependent variable, the model $R^2$ was 0.326. The results of this study suggest that a highly varied diet in elderly might be associated with better nutritional quality, as assessed by nutrient intake. Accordingly, dietary guidelines should take into consideration nutritional characteristics in order to improve intake from all major food groups and to provide a variety of foods in the diet.

The prevalence rate of metabolic syndrome has increased rapidly among the middle-aged and seems to be affected by socioeconomic factors, lifestyles and dietary habits. This research tries to find out the difference in dietary intake between middle-aged with and without metabolic syndrome. Using Korean National Health and Nutrition Survey (KNHANES) in 2005 and 2007, this study investigated 2,382 people (normal: 1,575, disease: 807) in 2005 and 1152 people (normal: 747, disease: 405) in 2007 (between the age of 40 and 64). Analysis was performed to discover the difference in nutrient intakes between people with and without metabolic syndrome. Also differences among people with various socioeconomic factors (such as age, education level, and income level), which can affect nutrient intake, were analyzed. In the nutrient intake people with metabolic syndrome has lower intake in most of nutrients than those of normal group, except carbohydrate. In 2007, normal group had higher intake in most nutrients, except for carbohydrate, sodium, potassium and vitamin A. Carbohydrate: protein: fat (C: P: F) ratio for metabolic syndrome group showed higher rate for carbohydrate, than normal group, in 2005, and 2007. Overall, the higher age and income level, the more carbohydrate intake rate is increase in metabolic syndrome group. The Quality of each nutrient intake was assessed using NAR (Nutrient adequacy ratio) and MAR (Mean adequacy ratio). According to the MAR, there was significant difference in 2005, 0.83 for normal group and 0.81 for metabolic syndrome group but there wasn't any in 2007 (0.81 for normal group, 0.82 for metabolic syndrome group). By NAR, in 2005, all nutrient except phosphorus, iron, vitamin A for Normal group higher then those of metabolic syndrome group (p < 0.05). In 2007 intake of metabolic syndrome group were higher then those normal group in most of nutrient by NAR. For age, education and income, MAR for normal group is higher then that of metabolic syndrome. In conclusion, Quality of nutrient intake in normal group is better then in metabolic syndrome group. Therefore, it is necessary to monitor dietary of intake people with metabolic syndrome, and necessary measures should be taken.

Body content bone mined density and nutrient intake status of 129 college women in Daegu area are analyze4 The mean age was 23.1 years. Bone mineral density was measured in their right heel by SONOST-2000 ultrasound bone densitometer, and nutrient intake was assessed by a Questionnaire. Diet intake data were obtained by using a 24 hours recall method to evaluate the subject's usual diet. The average energy, Ca, Ee, Zn and folate intakes were 64.2, 47.5, 54.7, 62.9 and $57.4\%$ of RDA, respectively. Ca/P and Ca/Protein ratio were 0.46 and 6.7, respectively. The mean adequacy ratio(MAR), an index of overall dietary quality wag 0.6. The index of nutritional quality was under 1.0 for protein(0.7), vitamin A(0.9), E(0.7), $B_1(0.8)$, niacin(0.8), $B_6(0.6)$ and phosphorus(0.6). The less the protein and energy intake, the less the bone mineral density(p<0.05). The intakes of protein(p<0.05) and that of phosphorus(p<0.001) were positively correlated with bone quality index(BQI). The calcium intake was positively correlated with Z-score(p<0.05). The phosphorus intake was positively correlated with T-score(p<0.001) and Z-score(p<0.0001). In conclusion, this study indicates that nutrient intake of the college women is considerably lower than the RDA. Also the BQI is lower than standard.

Nutrition is one of the factors influencing cognitive functions. But, the role of nutrition on cognitive functions within the elderly is recognized to a lesser degree. The aim of this academic endeavor was to analyze the affiliation between nutritional status and cognitive functions of the elderly in Korea. 316 subjects, of 114 male and 201 female aged above 65 years, were gathered from university hospital clinics, Elderly Welfare Centers, and Health Welfare Centers located in the district of Seoul, Gyeonggi province, and Incheon in Korea. The cognitive function was tested by the Korean-Mini Mental State Examination (K-MMSE) questionnaire. Nutrition intake was assessed by a 24-hour recall, a food frequency questionnaire (FFQ). Nutrition adequacy and quality were assessed by the Nutrition Screening Initiative (NSI) checklist, the nutritional adequacy ratio (NAR), and the mean adequacy ratio (MAR). The elderly with normal cognitive function status displayed significantly higher levels of calcium, riboflavin, thiamin, folate, vitamin C, vitamin E, vitamin B6, phosphorous, potassium, iron, niacin, zinc, animal fat, animal protein, polyunsaturated fatty acids, total protein, vegetable oil, vegetable protein, fiber than levels of the elderly with moderate cognitive impairment. The K-MMSE score positively correlated with of high consumption of pork, white radish, sea mustard, tomato, tangerine, grape, apple, and ice cream, and K-MMSE was negatively associated with high intake of potato, anchovy, fish cake, and mushroom. The findings suggest that nutritional status is affiliated with cognitive function within the elderly of Korea. The consumption of variety of foods and nutrients ensures adequate cognitive function in the Korean elderly.

The nutritional status of pre-school children is important for both physical growth and functional development. This study investigated the anthropometric, nutrient intakes and dietary quality of the pre-school children living in Asan for planning nutritional education program. The dietary intakes were measured by 2-day 24 hr recall recorded by children's mothers and the anthropometric data were collected by measuring children's weights, heights, and percent body fat at Asan Public Health Center. The children were 161 boys and 129 girls aged 5 and 6 years. When children's nutritional status was determined by their anthropometric status (underweight, normal weight and overweight) determined by z-score (normal range between -1.00 and 1.00), only 1.4% of the children belonged to underweight group while 55.7% and 42.9% belonged to normal and overweight groups, respectively. Significantly higher number of children belonged to overweight group for 5 year-olds. No differences were observed in nutrient intakes, nutrient adequacy ratio (NAR) and index of nutritional quality (INQ) values among nutritional status groups. Intakes of the most nutrients were adequate, but NAR and INQ of calcium and zinc were low. When nutrient intakes, NAR and INQ were compared by sex or age, all nutrient intakes were appropriate except calcium and zinc intakes of 6 year-olds. Nutrient intakes of 5 years were higher than those of 6 years. The mean of nutrient adequacy ratio (MAR) was 0.85 and mean INQ was 1.51 for all participants. The nutritional management program for pre-school children in Asan would be directed differently by age groups and education material should contain contents educating to consume moderate amount of food for 5 year-olds and to increase intake of foods with mineral nutrients such as calcium and zinc for 6 year-olds.

To assess the food intake and diet quality of Korean adults living in rural areas , a dietary survey using a one day 24-hour recall method was conducted with 2037 subjects over 30 years of age living in Yeonchon-gun , Kyungki province of Korea. Eighty percent of total food intake was in the form of vegetable food and the rest in the form o fanimal food . Diet quality was assessed by food group pattern, dietary diversity score(DDS), and dietary variety score(DVS). When counting the major food groups consumed (DDs), 47% of subjects had a DDS of 3 and 31% of subjects had a DDs of 4. On average, subjects habitually consumed 14.9 different foods daily, with the mean score of diet variety (DVS) for males(14.4) being significantly lower than for females (15.2). Persons who had higher DDSS also had higher DVSS(p<0.001). As the DDs increased , MAR(Mean adequacy ratio) improved. Correlation coefficients between NAR(nutrient adequacy ratio) and DVS ranged from r=0.34 for vitamin C to re=0.51 for vitamin B$_2$. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR of most nutrients with DVS was better than those with DDS. Based on these results, the food intake of the study subjects was not adequate, especially with regards to the dairy and fruit groups . Dietary diversity (DDS) and especially dietary variety (DVS) would be useful in assess nutrient intake because of their associations with total diet quality.

This study was conducted to assess the dietary intake of college students in Gyeonggi-do. The dietary survey data were obtained by a semi-quantitative food frequency questionnaire given to 103 students, 56 males and 47 females. The average age the of subjects was 22.5 years old for the male students and 20.9 years old for the female students. Among the subjects, 38 males and 26 females' height, weight and percentage of body fat were measured using Inbody 3.0. The average height, weight, Body Mass Index(BMI) and percentage of body fat of the subjects was 173.1cm, 68.6 kg, 22.9 and 18.9% for males and 162.5 cm, 54.1 kg, 20.5 and 28.1% for females, respectively. The mean daily intake of energy was 2,343.0 kcal for males and 2,062.0 kcal for females. The average intake of protein, carbohydrates, Vitamin B1 in the male students were significantly higher than those of the female students(p<0.05). The average of Nutrient Adequacy Ratio(NAR) was ranged from 0.60(folate) to 0.99(phosphorus). NAR of Vitamin A and calcium was 0.71 and 0.75, respectively. The average of Mean Adequacy Ratio(MAR) was 0.85. The intake of rice and oriental cereals(sum of the parched cereal powder, ramen, noodles, Chajangmyon, buckwheat vermicelli, buckwheat noodles, dumplings and rice cakes) in the males was significantly higher than those of the females. The intake of snacks in the females was significantly higher than that of the males. Appropriate nutritional education for an optimal intake of nutrients may help to improve the quality of diet in college students.

The purpose of this study was to compare the nutrient intake and diet quality of male college student according to smoking groups. Subjects were recruited and divided into three groups according to the smoking, which included non-smoker (n = 100), light-smoker (n = 78; packyear < 5), and heavy-smoker (n = 76; packyear ${\geq}$ 5). Subjects were interviewed using a general questionnaire, 24-hour recall method for dietary intake and diet quality. The average age of the subjects were 22.7 years for non-smoker, 23.5 years for light-smoker, and 23.4 years for heavy-smoker. Also the results showed that the heavy-smoker was significantly more often to drink coffee and alcohol compared with the other two groups (p<0.001, p<0.05). The mean daily energy intake was 2278.1 kcal in non-smoker, 2148.3 kcal in light-smoker, and 2144.4 kcal in heavy-smoker. The heavy-smoker consumed significantly lower intakes of vitamin C (p<0.001), calcium (p<0.01), animal calcium (p<0.01), and potassium (p<0.05) compared to the non-smoker and light-smoker. Also NAR (Nutrient Adequacy Ratio), ND (Nutrient Density), and INQ (Index of Nutritional Quality) of these nutrients in heavy-smoker were lower than the other two groups. Mean adequacy ratio (MAR) was 0.78 in non-smoker, 0.78 in light-smoker, and 0.74 in heavy smoker (p<0.05). The heavy-smoker consumed significantly lower intakes of fruits (p<0.001) compared to the non-smoker and light-smoker. The DVS (Dietary Variety Score) of heavy-smoker (26.8) was significantly lower than that 30.4 of non-smoker and 31.5 of light-smoker (p<0.01). In conclusion, heavy-smoker man have low intake status of vitamin C, calcium and potassium, and partly low diet quality. Therefore it was needed that well planed diet to replace the nutrients supplied from excluded food groups in heavy- smoker.

Objectives : The purpose of this study was investigation of quality and quantity of nutritional intake related oral health status among Korean elders. Methods : The nutrient intake and the dietary quality was evaluated on the basis of the Dietary Reference Intakes For Koreans(KDRIs). Chi-square test for Complex Samples was used to determine the relationship between oral health and inadequate nutrient intake in Korean elders. The complex samples general linear model was used to test difference of average value difference of nutrient intake percentage compared to dietary reference intake(DRI), energy intake rate from three major nutrients, average mean adequacy ratio(MAR) and index of nutritional quality(INQ) related oral health status. Age, sex and total energy intake was compensated for this analysis. PASW 18 was used for statistical analysis. Results : We could found the difference of the nutrient intake and the dietary quality related oral health status among Korean elders. Especially, Nutrient intake percentage and component ratio of protein among energy intake rate from three major nutrient was lower as oral health status became worse. The percentage of subjects with nutritional intakes under showed highest level in worst oral health status. As oral health status became worse, average mean adequacy ratio(MAR) was lower and the number of nutrient of which index of nutritional quality(INQ) was under 1 was more. Conclusions : From the result above, this study clearly shows the level of oral health affecting the inequalities of eating and the food for the people. And the various propose of oral health policies is needed for vulnerable groups who needs solution to solve the problem of inequality of food distribution where intensive distribution of nutrition problem occurred. Sufficient, safe, and a variety of healthy food intake is a fundamental right of our people. And also, to apply this policy in reality, institutional arrangements and organizations, and specific performing system will be needed.
