Dietary Variety Score (DVS) or Nutrient Adequacy Ratio (NAR) offers a way of comparing eating habits across populations and across countries. This study compared nutrients intakes, food intakes, DVS, and NAR between Korean and US adults using the large national survey data. 4662 Korean adults (men: 2201, women: 2461) aged 20-49 years were selected from the 'Korean National Health and Nutrition Survey,2001' and 4199 US adults (men: 2127, women: 2072) aged 20-49 years were selected from the 'US National Health and Nutrition Examination Survey (NHANES IV,1999-2002)'. The total plant food intakes were high in Korean adults, but the total animal food intakes were high in US adults. Intakes of legumes and nuts, vegetables and mushrooms were higher in Korean than in US adults. On the other hand, intakes of meats, milk and dairy products of US adults were higher than Korean. Beverage intakes were 8 - 10 times higher in US adults than in Korean. The mean DVS of Korean men and women were higher than US men and women. Intakes of fat, calcium and vitamin $B\_{2}$ of US adults were 1.5 - 2 times higher than those of Korean, which could probably related to larger consumption by US adults on milk and dairy product. While the intakes of carbohydrate and vitamin C of the Korean were higher than the US adults, which could presumably related to higher grain and vegetable consumption. Percent energy intakes from carbohydrate, protein, and fat were $64.1\%$, $15.8\%$, and $20.1\%$ for Korean men, $52.4\%$, $15.0\%$, and $32.6\%$ for US men, $65.9\%$, $14.9\%$, $19.2\%$ for Korean women, and $52.1\%$, $14.7\%$, $33.2\%$ for US women respectively, which showed higher $\%$energy from carbohydrate in Korean and higher $\%$energy from fat in US adults. Most nutrient intakes except energy and vitamin C expressed as $\%$RDA were higher in US than in Korean adults. Mean Adequacy Ratio (MAR) of US men and Korean men were both 0.85, while the MAR was 0.81 for Korean women,0.79 for US women. The Korean women's diet showed more diverse and adequate than the US women's diet.

This study was conducted to compare the nutrient content of rice-based meals and wheat-based meals. The subjects consisted of elementary school children, middle school students, high school students, college students and adults living in the Miryang and Daegu area. A dietary survey was conducted using a 24-hour recall method and data were collected from 941 subjects. Nutrient contents were analyzed by CAN Pro. All nutrient contents in rice-based meals, except vitamin B2, were higher than those in wheat-based meals. But lipid and cholesterol contents of wheat-based meals were higher than those in rice-based meals. Comparing age groups, all nutrient contents obtained from rice-based meals, except vitamin B group, were higher than those in wheat-based meals in all age groups except the adult group. In the adult group, protein, fiber, vitamin A, niacin and vitamin C were consumed higher from rice-based meals, but energy, lipid, calcium, iron, vitamin B and cholesterol were consumed higher from wheat-based meals. lipid and cholesterol contents of wheat-based meals were higher than those of rice-based meals in all age groups, except elementary school children. When compared the nutrient intakes of Korean RDA, major nutritional problems of each age groups were due to the inadequate intakes of calcium and iron. And all nutrient contents, except vitamin B group, in wheat-based meals were very low in every age group.

This study was conducted to provide basic information on the nutritional status and dietary behaviors of the deaf teenagers. The subjects of this study were 87 deaf-mute high school students in Pusan and Kyung-nam area and, in comparison,90 general high school students in Ham-an area. The survey was investigated by using a self-administered questionnaire. The results were as follows: Deaf-mute group was consisted of 63.2% male and 36.8% female, and mean of height and weight of male were 171.2 cm and 61.9kg, female were 158.0cm and 51.7kg. Obesity index and body mass index (BMI) were normal range in both deaf-mute and normal groups. The average nutrition knowledge score of the deaf-mute group was 6.8 $\pm$ 1.5 out of possible 10 points, that was significantly lower than 7.3 $\pm$ 0.8 of the normal group (p<0.01). The mean of self-control and conscious control scores in the eating behaviors of the deaf-mute group were 2.6 $\pm$ 1.2 and 2.4 $\pm$ 1.3 out of possible 5 points from each item, which was significantly higher than 2.1 $\pm$ 1.3 and 1.8 $\pm$ 1.4 of the normal group (p< 0,01). Nutrients consumed below 90% of Korean RDA were energy (79.9%), Ca (71.5%) for deaf-mute male students and Ca (88.5%) for deaf-mute female students. Energy (71.4%), protein (87.8%), Ca (74.8%), vitamin B$_1$ (83.4%) intake of normal male students and energy (72.8%), Ca (71.2%), Fe (78.7%) intake of normal female students were below 90% of Korean RDA. Energy, protein, fat, vitamin B$_1$, niacin intake of deaf-mute male students were significantly higher than normal male students and all nutrients intake of deaf-mute female students were significantly higher than normal female students. By the correlation of nutrients intakes with nutrition knowledge, there was positive correlation with the intakes of Ca, Fe, vitamin A, vitamin B$_2$, and vitamin C in the deaf-mute group, while there was negative correlation with the nutrients intakes (except for protein and fat) in the normal group. The amount of meal, breakfast, regularity of meal time, frequency of snacks showed a positive relation to nutrient intakes in deaf-mute group and amount of meal, breakfast, regularity of meal time, frequency of overeating showed a positive relation to nutrient intakes in normal group. The nutrition knowledge had no correlation with food habits or eating behaviors in both groups.(Korean J Nutrition 35(9) : 982~995, 2002)

The present survey was designed to investigate correlations among blood pressure, nutritional intakes, and various environmental factors in Korean adult males, and to observe the difference in dietary intakes between hypertensive patients and normotensive subjects. Two hundred forty-three adult men from Seoul and rural areas were interviewed about their food intakes, dietary patterns, food habits, and general environmental factors from December 20, 1982 to February 15, 1983. Their dietary intakes were surveyed by means of 24-hour recall diet method. Dietary score card was used in order to evaluate the quality of routine diet of the subject. Variables of environmental factors and factors related to hypertension were expressed as percentage, and the differences in nutrient intake and food score of each sub-group were examined by means of t-test. Correlation of all the variables were analyzed by Pearsons Correlation Coefficient. The results obtained are summarized as follows: 1. 38% of the subjects were between the ages of 40~49, and about one-half of the subjects were middle or high school graduates. 28% of the subjects earned 210, 000~350, 000 Won per month, and income distribution was almost identical to that of the urban population of Korea. 2. There was more overweight or obese found in the hypertensive patients than in the normotensive subjects. About 40% of the hypertensive patients reported a family history of hypertension, and their knowledge about hypertension was rather poor, but slightly better than the normotensive subjects. The patient group had less adherence to smoking and alcohol compared with the normotensive subjects, but no difference was observed in coffee drinking. The mean value of the blood pressure for the normotensive subjects was 127/86mmHg and 175/109mmHg for the hypertensive group. 3. Nutrient intake for the hypertensive group was lower for most of nutrients than in the healthy group. Hypertensive patients on diet therapy consumed less calories and carbohydrates compared with those who do not follow diet therapy. 4. There was no difference intake of these food groups between patients and the healthy group. Food score was strongly related to consumption of animal protein, saturated fats, Calcium, Iron, Vitamin A, Riboflavin, and Vitamin C, which are prone to be deficient in the typical Korean diet. 5. Blood pressure had a strong positive correlation with age, body weight, and socioeconomic level. In addition, monthly income was positively related with age and education level. 6. Three was a positive relationship between blood pressure and consumption of vegetable protein, and a negative relationship with consumption of Calories, Carbohydrates, Calcium, Iron, Vitamin A, Vitamin B1, Niacin, and Vitamin C. Animal protein intake increased as income and education levels increased, but this tendency was opposite for carbohydrates. In summary, nutritional intakes are strongly correlated with various environmental factors and the level of blood pressure. There was no difference between normotensive and hypertensive subjects with respect to the quality of food consumed except restricting energy and carbohydrate in the patient group.

The purpose of this study was to investigate to the effect of regular exercise on nutrients intakes and energy balance related to food habit and nutrient knowledge of college women. This study was conducted from May to June in 2000. One hundred and forty female students made their three day dietary records by 24-hr recall method and one day activity record. The questionaires were designed to fine out food habit and nutrition knowledge status. The height. weight and blood pressure were measured and also body fat mass and lean body mass measurements were performed. The results obtained are summerized as follows. Average height and weight of E(exercise) group were found to be increased than those of NE(non-exercise) group. The percent of body fat and body fat mass(kg) in E group were slightly lower than those of NE group. Calorie intake of NE group was 1,664kca1 per day. This was composed of carbohydrate 60%kcal. protein 14%local and fat 24%local. Calorie, calcium, iron, vitamin A, vitamin B$_2$ and niacin intakes of NE group were lower than those of RDA and calorie intake of E group was 2.313kca1 per day. This was composed of carbohydrate 54%, protein 13% and fat 31%. Other nutrients such as iron, vitamin A, niacin and vitamin C were lower than those of RDA. Daily energy expenditure and physical activity of E group were 2,397.6$\pm$49.2kca1; 1,035.7 $\pm$36.5kcal, respectively and it was higher than those of NE group.

Nutrients intake status of 73 lactating women, that is 45 breast feeding (BF), 13 formula feeding (FF) and 15 mixed feeding (MF), living in Daejeon was investigated. Self-recorded food intakes for two weekdays and eating behaviors using questionnaires were surveyed from May to August 2008. Subjects aged $29.2{\pm}3.4$ years and their infants aged $8.2{\pm}3.2$ months. Body mass index of the subjects was $21.0{\pm}3.2$. Of the subjects 23.3% were employed. Daily energy intake was $1953{\pm}391$ kcal. Mean adequacy ratio (MAR) was $0.77{\pm}0.14$ and was higher in FF ($0.86{\pm}0.13$) than in BF ($0.76{\pm}0.11$) and MF ($0.72{\pm}0.18$). Nutrients that over 50% of the subjects took less than estimated average requirement were vitamin A, riboflavin, folate, vitamin C and calcium. And index of nutritional qualities of those 5 nutrients were below one Forty six and sixths percent (46.6%) of the subjects showed GMFVD = 11111 pattern of five food group intakes and 57.5% took meals three times daily, 56.2% skipped often breakfast, and 64.4% dined out two times and more per week. Subjects having lower MAR (< 0.72, n = 24), compared with those having higher MAR (${\geq}$ 0.83, n = 24), showed more skipping daily meals and less frequency of eating-out, and took less legumes, vegetables, fishes, and milk. As the results, intakes of calcium, vitamin A, riboflavin, folate, and vitamin C were insufficient in lactating women, especially in BF and MF mothers. Meal skipping and low intakes of dairy foods, legumes, vegetables, and fishes might have adverse influences on nutritional status of lactating women. Accordingly, nutrition care program for lactating women should be focused on intake of three meals daily and a variety of food.

This study was performed to assess diet qualities by sexes and ages of adults over thirty years old in Jeon-ju area. Diet survey with one day 24-recall method was used done for 382 subjects(129 males & 253 females). Survey sample was divided into six groups by sex and age groups: male 30-49, male 50-64, male 50-64, male 65-79, female 30-49, female 50-64 and female 65-79 years. Diet quality was assessed by NAR(Nutrient Adequacy Ratio), MAR(Mean Adequacy Ratio), INQ(Index of nutrition quality), KDDS(Koreans Dietary Diversity Score), Meal Balance, DVS(Dietary Variety Score), DQI(Diet Quality Index). The 5-point DQI assessed the important dietary guidelines for Koreans. The averages of energy, protein, P, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than 70% of RDA. The averages intakes of Ca and vitamin A were very lower than RDA all groups. The averages of MAR were 0.78, 0.81, 0.83 in male 30-49, 50-64, 64-79 years, 0.73, 0.77, 0.71 and in female 30-49, 50-64, 65-79 years, respectively. The averages of MAR in female 30-49 years and female 65-79 years were significantly lower than the averages MAR of male 65-79 years. The averages of Sugars and Beverages intakes were significantly higher in male 30-49 years than others. Animal food intake ratio(% total food intake) in the male 65-79 years(16%) was significantly higher than male 30-49 years(11%). The averages of Nutrition intakes were higher in male compared to female. The subjects who consumed all of the major five food groups were 5% in male 30-49, 17.8% in male 50-64, 25.0% in male 65-79 years, 18.9% in female 30-49, 23.7% in female 50-64, 11.5% in female 65-79 years. The averages of KDDS were 3.5, 3.9, 3.9, 3.8, 3.8, 3.5, respectively. The averages of Meal Balance were 8.6, 9.1, 9.1, 8.3, 8.4, 7.8, respectively. The averages of DVS 20.1, 19.9, 19.9, 20.5, 19.0, 17.2, respectively. The averages of DQI were 1.7, 2.2, 2.1, 2.0, 2.1, 1.7, respectively. 81.8% of the subjects had KDDS scores of 2 to 4 and 87.3% of the subjects has Meal Balance scores 4 to 10. In contrast, 89.8% of the subjects had DQI scores of 0 to 3. In view of these facts there are few who observed the five dietary guidelines for Koreans. There findings suggest that dietary qualities were associated with nutrient intake the relation factors may vary by sex and age of adults over thirty years old in Jeon-ju area. Common problems were lack of Ca, vitamin A and dairy products intakes. Therefore adults over thirty years old in Jeon-ju area need the important nutrient management such as Ca, vitamin A.

Objectives: This study examined the effects of nutrition education focused on personalized daily energy requirement and food units using Food Exchange System on anthropometric, biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes for overweight and obese in a public health center. Methods: The subjects were 60 overweight/obese women based on BMI (educated 30 vs. non-educated 30, 50~64 years). Educated group was provided individual and/or group lessons (40 min/lesson/week, 5 week), 'Introduction: obese & health', '6 nutrients and 6 food groups', 'My obesity & daily needed energy', 'Meal planning for personalized daily energy and food units using Food Exchange Systems', and 'Smart food choices'. After education, we examined the differences in anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes between educated group and non-educated group. Results: After nutrition education, in the educated group, there were improvements on anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes in the educated group compared to the non-educated group. We observed a decrease in the mean weight, total cholesterol (TC) and the incidence of overweight/obesity and hypercholesterolemia and an increase in the mean lean body mass. The scores of nutrition knowledge, 'Function of carbohydrate, protein, vitamin, mineral' and 'Food Sources of fat, vitamin, mineral' were increased. The scores of dietary attitudes, 'Taking a joyful meal, a leisurely meal, a balanced meal, a meal with sufficient vegetables, a meal with diversity, a meal with spicy foods, a meal with overeating' were increased. The intakes of energy, carbohydrate, fat, protein, vitamin A, thiamin, Zn and cholesterol were decreased. The scores of INQ, protein, vitamin A, vitamin C, thiamin, riboflavin, vitamin B6, folate, Ca, P, Fe, Zn were increased. Conclusions: The nutrition education focused on personalized daily energy requirement and food exchange unit using Food Exchange System for overweight and obese may improve food behavior, dietary intakes and symptoms of overweight and obese, even in a community health center.

Previous studies have indicated that incidence of rheumatoid arthritis (RA) is partly related to the damage of antioxidant systems, but etiology of RA is not fully identified. This study was performed to evaluate nutrient intakes including antioxidants, health related behaviors and food habits of RA patients and controls. RA patient group (n = 68) and sex-matched healthy controls (n = 68) were joined in this study. Nutrient intake was estimated using a semiquantitative food frequency questionnaire. As mean age of RA ($52.9{\pm}13.8$ years) was significantly higher than those of controls ($48.7{\mp}5.9$ years), data were analyzed by using Student's t-test, adjusted for age. There was no significant difference between two groups in body mass index. Compared with those of controls, frequencies of drinking (p < 0.001) and coffee consumption (p < 0.05) of RA groups were lower. RA groups had lower frequencies of fruit (p < 0.01), vegetable (p < 0.05) and fatty meat (p < 0.05) consumptions and balanced diet (p < 0.01), and higher frequencies of fried dishes (p < 0.01), and salty dishes (p < 0.01), compared to controls. The most nutrient intakes including energy intake of RA were tended to be lower than those of controls. Vitamin A, ${\beta}$-carotene and vitamin C intakes were significantly lower in RA than controls (p < 0.001). Daily vitamin A, ${\beta}$-carotene and vitamin C intakes of RA were lower than those of control (vitamin A: RA $360.6{\pm}252.23{\mu}g$ RE, control $844.5{\pm}426.2{\mu}g$ RE, p < 0.001; ${\beta}$-carotene: RA $1450.9{\pm}1019.0{\mu}g$, control $3968.8{\pm}2248.21{\mu}g$, p < 0.001; vitamin C; RA $40.6{\pm}21.48mg$, control $84.7{\pm}40.29$, p < 0.001) These results suggest sufficient consumption of antioxidant nutrients may prevent and improve RA status.

This study was undertaken to assess nutritional status of the low income elderly residing in Gwangju. Anthropometric data showed that mean height of the subjects was lower than that of Korean Standard Growth data but weight was similar to that standard value. As the subjects became older, their heights and weights were decreased. Body mass index (BMI) in males and females were 22.9 and 24.4 respectively. However, BMI distribution showed that 56% of the elderly females under 75 were underweight. Advancing age conoibutes significant difference in triceps skinfold thickness in females (p < 0.001). Total cholesterol level was higher in the elderly females than the males. It was found that a considerable number of subjects had anemia determined by hemoglobin and hematocrit level, which indicated un iron deficiency. Twenty-four hour dietary recall revealed that, except for phosphorus and vitamin C, all the nutrient intakes of the subjects were below 75％ of Korean RDA. Surprisingly, vitamin A and riboflavin intakes of the elderly were below 50％ of Korean RDA. Energy intakes of the elderly males and females were 58.7% and 59.6% of Korean RDA respectively. Unbalanced energy ratios of carbohydrate, protein and fat were noted in both genders. Nutrient intakes of females' were lower than those of males'. Thus, there was a significant gender difference in nutrient intakes. It might be further suggested that an appropriate nutritional program should be developed and implemented to improve the Poor nutritional status of the low income elderly living in cities.
