To assess diet quality by food group intake and to investigate the interrelationship of age, dietary diversity score(DDS), dietary variety score(DVS), dietary frequency score(DFS), food group intake and nutrient intake with food group intake, a dietary survey was conducted with 176 preschool children aged 1 to 6 in Busan using a 24-hr recall method. Food group intake was assessed by food number consumed and intake frequency by six food groups(grain, meat, vegetable, fruit, dairy, sweets group). The mean food numbers consumed and intake frequencies by six feed group were 3.1 and 4.0 in the grain group, 3.6 and 4.0 in the meat group, 3.5 and 4.1 in the vegetable group, 1.0 and 1.1 in the fruit group, 1.3 and 1.5 in the dairy group, 1.4 and 1.4 in the sweets group respectively. As age increased, the intake frequency of the grain group(p<0.05) increased but that of the dairy group(p<0.05) decreased significantly. The DVS and DFS didn't show significant correlations with intake frequency of the dairy group. The grain group intake had significant positive correlations with intakes of the meat, vegetable, and fruit groups. The vegetable group intake had signigicant positive correlations with intakes of the grain and meat groups. The dairy group intake had significant positive correlation with sweets group intake but negative correlations with intakes of the grain and vegetable groups. As the intake frequency of the meat group increased, the NAR(nutrient adequacy ratios) of all nutrients and NAR(mean adequacy ratio) increased significantly. NARs of provein iron, vitamin B$_1$, niacin had the highest correlation with the meat group intake and those of protein, calcium, phosphorous, and vitamin B$_2$ had the highest correlation with the dairy group intake. NARs of vitamin A and vitamin C had the highest correlation with intake of the vegetable and fruit groups respectively. Children with food number consumed and intake frequency of above 6 and 4 in the grain group or above 6 and 6 in the meat group or above 4 and 8 on the

Intake frequency of one food is often associated with other food items, but few studies examined the relationship of food intake frequency among food items. Finding the relationship among intake frequencies of different food might be useful to understand the food intake patterns of population and correlated foods would be used as an indicators of another food intake. Relationship of food intake can be also applied to make a more simple and useful form of food frequency questionnaire to assess the association between diet and various diseases. The objective of this study was to examine the correlation of intake frequency among food items in food frequency questionnaire (FFQ). A FFQ with 84 food items was administered to 14533 Korean males who 40-65 years of age participating Korean cancer research survey. Data fromm 7647 subjects who completed FFQ were used to examine correlation among food items with three different methods-log linear regression models, Spearman correlation coefficients and cell frequency distribution. To examine the rank correlation, coefficients were calculated by Spearman correlation after scoring the frequency categories. Three most correlated foods were selected in every food intems by three methods each. In most food items, there was positive correlatin, except cooked rice and cooked brown rice, in intake frequency between foods that belonged to similar food groups. But serveral food items-Sausage (processed fish, cheese), Milk (whilte bread, orange juice), Soymilk(other juices), Cheese (pizza, butter), and Coffee(thick beef soup)-showed correlation among totally different food groups. Two sets of food items which were selected by log linear regression model and Sperman correlation coefficients were compared. There were exactly three common foods in 18 food items, 2 common foods in 47 items, 1 common food in 16 items and no common food in 3 items among 3 ranked foods. Three sets of selected food were compared. There were exactly three common foods in 5 food items, 2 common foods in 21 items, 1 common food in 34items and no common food in 24 items among 3 ranked foods. These results indicate that certain patterns exist among intake frequencies of specific food items in the FFQ. More researches are suggested to understand the relationshiops among the intakes of foods so that this information can be used in developing better FFQ or analyzing missing items from self-administered FFQ.

Objective: The purpose of this study was to investigate the effect of food intake on the Fourier components of radial pulse wave. Methods: Thirty-one healthy male subjects participated in this study. Radial pulse was measured using 3 dimensional pulse imaging system (DMP-3000) before, right after, 40 minutes after, 80 minutes after and 120 minutes after food intake. Fourier transform was performed and the frequency and amplitude of Fourier components were analyzed. Results: 1. The frequency and the amplitude of Fourier components of radial pulse wave increased significantly after food intake. 2. The frequency of Fourier components increased right after food intake and then gradually decreased as time passed, however the amplitude of Fourier components increased and maintained certain levels and patterns throughout the experimental period of 120 minutes. 3. The change ratios of the frequency and the amplitude of Fourier components after food intake varied with the pulse measuring locations. Conclusions: Food intake exerts an influence on radial pulse wave, resulting in increase of frequency and amplitude of Fourier components. The change ratios of the frequency and the amplitude of Fourier components after food intake varied with the pulse measuring locations.

The purpose of this study was to investigate the relation of the fast food and beverage intake on sociality and anger expression of adolescents. Questionnaires were distributed to the adolescents of 599 middle and high school students in Busan. According to the results, the preference-intake frequency analysis (PEA) on fast food grid, high preference and high intake frequency were 'dukbokki', 'chicken' and 'mandu' and low preference and high intake frequency were 'ramyon', 'gimbab. PEA on beverage grid, high preference and high intake frequency were 'milk-dairy product', 'fruit juice', 'isotonic beverage' and low preference and high intake frequency were 'carbonate drink'. The intake frequency of 'pizza', 'sandwich', 'udong', and 'dukbokki' had a positive relationship with sociality. 'Hamburger', 'chicken', 'french fry', 'gimbab', 'mandu', and 'ramyon' showed a positive relationship with anger-out. The intake frequency of 'carbonated drink' had a negative relationship with anger-control, but 'green tea' showed a positive relation with it. 'Carbonate drink', 'isotonic beverage', 'coffee', and 'milkshake' had a negative relationship with anger-out. The explanation power ($R^2$) of intake of fast food and beverage on sociality was $0.019{\sim}0.038$, and 'carbonated drink' and 'coffee' had a negative influence on sociality. The explanation power ($R^2$) of intake of fast food and beverage on anger expression was $0.011{\sim}0.041$, and 'carbonated drink' had a negative influence on angercontrol. 'Hamburger', 'carbonated drink', and 'coffee' showed a positive influence on anger-out. From these results, it was necessary to develop the practical eating-out habits program on proper fast food and beverage choice for adolescents.

The purpose of this study was to investigate dietary habits and food compliance in stroke patients. One-hundred sixty eight elderly stroke patients and 97 young patients with first -ever stroke admitted to Asan Medical Center between 1994 and 1998 were studied. Using a structured interview, we assessed food intake. food consumption frequency and compliance to low salt, low meat hight fish and high fruit and vegetable diets. These results were analyzed with X$^2$, t-tests, and analysis of variance (ANOVA) using the SAS package program. Salted food intake and cholesterol-containing food frequency were increased whereas frequency of fruits and vegetables intake was decreased in young stroke patients compared to the elderly. Meat intake and cholesterol-containing food frequency were increased in the males compared to the females in elderly stroke patients. and fish intake and cholesterol-containing food frequency were higher in the males than the females in the young. In patients with high economic status, frequency of fruits and vegetables was elevated. Also compliance the low meat and high fruit and vegetable diet in young patients was lower than that in the elderly. When the life-style risk factors influencing the food intake of frequency of fruits and vegetables was affected by education in young stroke patients. In elderly stroke patients, meat intake frequency of cholesterol-containing foods and fruits and vegetables were influenced by sex and /or income. Our results suggest that dietary intake of salt meat ,cholesterol-containing foods. fruits and vegetables in stroke patients may vary with age, sex the presence of risk factors or economic status therefore guidelines and nutrition education should by formulated to prevent stroke recurrence based on dietary habits and risk factors of individual patients.

A survey was conducted to examine the food intake of 285 Korean female students attending a secondary school in Seoul. Food intake was assessed using a food frequency based on the Korean Food Tower which consists of five food groups, i.e., grain products, vegetables and fruits, meat, milk, and fats and sweets. To describe food intake descriptive statistics were obtained using SPSS. The food frequency analysis indicated that the participants ate rice, cabbage kimchi, radish, and soybean/red pepper paste most frequently along with milk, ice cream, tea, and seasonal fruits such as citrus fruits, apples, watermelon, and grapes for snacks. Distributions of the total standardized serving frequency for each food group indicated that approximately 84, 83, 45, 60, and 34%, respectively, of the respondents met the recommended serving frequency for grain products, vegetables and fruits, meat, milk, and fats and sweets groups(mean servings per day 5.5, 10.6, 5.5, 2.1, 3.5). Income was the only demographic factor that affected food intake, particularly with respect to meat, milk, and fats and sweets(p < .01). In Korea, these food groups are generally more expensive than the other ones. (J Community Nutrition 4(3) : 164∼179, 2002)

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.

This study was conducted to find sensitive indicator of food intake and specific food group related to cognitive function and to analyze the pathway among factors affecting food intake and cognitive function of the aged. 179 people over 50 years old were investigated and all the data were analyzed by SPSS 10.0 package. Food frequency was more sensitive indicator to show the relationship between food intake and cognitive function of the aged than the numbers of standard amount of food eaten. Consumption of grains and starch, meat, fish, eggs and beans were strongly related to cognitive function of the aged and intake of vegetables and fruits also have relationship with it. Moreover, the more frequent eating the carbohydrate and the protein, the higher the cognitive level of the aged. Age, education period, income, blood pressure, duration after retirement, frequency of physical activity and BMI were correlated with food intake and cognitive function of the aged. Among them, age and frequency of physical activity were most strongly correlated with food intake, and education period with cognitive function of them. This investigation shows that more stable intake of carbohydrate and protein containing foods need to be supplied to low income aged and the importance of physical activity of the aged must be emphasized with food intake for better life of the aged.

o assess the food intake and the sodium and potassium intakes and urinary excretion of preschool children in Pusan and to evaluate the relationship among variables dietary behaviors food and nutrient intake and 24hr urinary sodium and potassium excretion were measured with 97 subjects. The mean sodium and potassium intakes were 1890. 1mg(82,2meq) and 1479.7mg(37.8meq) respectively. The mean potassium intake(p<0.05) and density(p<0.01) were significantly low at the group who had food intake pattern absen of fruit and daily groups. The mean urinary sodium and potassium excretion were 735.3mg(32.0meq) and 418.7mg(10.7meq) respectively. The mean sodium intake(p<0.01) and urinary excretion were 735.3mg(32.0meq) and 418.7mg(10.7meq) respectively. The mean sodium intake(p<0.01) and urinary excretion (p<0.001, p<0.001) energy intake(p<0.01) sodium intake and density (p<0.001, p<0.05) the food number and intake frequency of vegetable group consumed (p<0.01, p<0.01) dietary frequency score(p<0.05) and negative correlations with the food number and frequency of dairy group consumed (p<0.05 p<0.05) The urinary potassium excretion showed positive correlations with height and weight(p<0.05, p<0.01) urine volume and urinary creatinie excretion(p<0.01 p<0.001) potassium intake(p<0.05) food number and intake frequency of dairy group consumed (p<0.05, p<0.001). Based on the results urinary sodium excretion was related to age sodium intake and food intake of vegetable and dairy group and urinary potassium excretion was related to potassium intake and food intake of dairy group. So nutritional education is needed in order to decrease sodium intake especially from food intake of vegetable group when preschool children have less food intake of diary group,.
