The objective of this study was to investigate difference in the diet by the kind of meal and the economic status. Nutrient contents at each meals were compared and differences in food intake at different meal were analyzed by economic status. Data from the 1998 Korean National Health Examination Nutrition Survey were used. Using the poverty line based on the 1998 Korean minimum cost of living, the subjects (n = 10400) were classified into high class (36.1％), middle class (40.7％) and low class (23.1 ％). Most nutrient intakes were obtained for main meals regardless of economic status. For high class, breakfast, lunch, dinner and snacks bring about 21, 29, 30 and 19 ％ of total energy intake, for middle class 22, 29, 30 and 19％ and for low class 24, 30, 30 and 16％, respectively. The high-middle class people tend to get more food intakes and nutrients at dinner and snacks, while the low class at main meals. This result was associated with the consumption of a smaller number of meals and a greater number of snacks daily as the economic level was going up (p 〈 0.05). Meals contributed to energy, protein and fat intake, and snacks to water, retinol and vitamin C. The food intakes by food group were different at meals by economic class. Seaweed product were popular breakfast foods in both middle and low groups. Thus three meals such as breakfast, lunch and dinner still delivered most of the energy and most of the macro-nutrients regardless of economic status.

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,.

Objectives: The objective of this study was to revise the target pattern in food guidance system for adolescents' balanced menu planning. Methods: The food groups in the target pattern were divided into detailed food items, and intake number were assigned to each food items based on the revised standard food composition table. The validity of revised target pattern was examined. Menu planning according to the revised target pattern was made available to 305 male and female middle school students and the nutritional assessment of the menu plan were carried out using SPSS WIN 12.0. Results: The energy contents, energy contribution ratios of carbohydrate, fat, and protein, and 4 minerals' and 6 vitamins' contents of the revised target pattern were adequate. The average energy contents of the menu planned according to revised target pattern were 400~500 kcal higher than that of the revised target pattern when the revised standard food composition was applied. The energy contribution ratios of fat were 28.9%, close to maximum of acceptable macronutrient distribution range (AMDR) (30%), and that of carbohydrate were 54.5%, lower than minimum of AMDR (55%). The nutrient adequacy ratios (NARs) of calcium and vitamin C were less than 1.0. According to index of nutritional quality (INQ) of food items, kimchi, milk dairy products, and soybean curd were energy efficient source for calcium, kimchi, fruit, vegetable and seaweed were energy efficient source for vitamin C, with INQ of food items were higher or close to 2.0. Kimchi was the best energy efficient source of calcium and vitamin C. Conclusions: Revised target pattern based on the adolescent's foods intake was not good enough for balanced menu planning by adolescents, because what they ate and what they wanted to eat were very much different. Detailed guidance for food selection is necessary in each food items.

The purpose of this study was to investigate the association between antioxidant food intake pattern and asthma control status in Korean adolescents. This study was conducted using data from 1,578 patients diagnosed with asthma among the participants in the 11th online health behavior survey. Statistical analyses were performed for sociodemographic variables, known risk factors for asthma worsening, and all variables which were related to food intake pattern. For final decision, logistic regression analysis was used to estimate the associations between antioxidant food intake and asthma worsening. Male gender and smoking experiences were associated with asthma exacerbation. Low intake of antioxidant foods status also significantly increased asthma exacerbations. Antioxidant food intake and smoking prevention education is important for adolescent asthma patients. It is highly needed to recommend taking fruits and vegetables properly.

This study was performed to investigate the preference and consumption pattern on milk and milk products of middle and high school students. The subjects were 1,195 students(590 middle school and 605 high school students) living in Geochang area. The survey was conducted by using a self-administered questionnaire in November, 2004. The results were as follows. Sixty-three point four percent of the subjects liked milk, and the main reason was 'accelerate growth and development'(55.4%). Preferred tastes of milk were 'savory taste'(35.4%) and 'sweet taste' (29.9%). Banana milk, chocolate milk, strawberry milk, ice cream, yoplait and yogurt were highly preferred. General preference for different kinds of milk was significantly higher in high school students and male students than in middle school students and female ones. With regard to preference for dairy products, cream (p<0.01) and butter(p<0.05) was preferred more by male students than by female ones, ice cream(p<0.05), yoplait (p<0.05) more by female students than male ones. The score of milk intake frequency was 3.84(3-4 times a week) out of 5 points(7 times a week) for white milk, and that of chocolate milk was 1.98, banana milk 1.96, strawberry milk 1.72, coffee milk 1.65, showing that these products were drank less then once a week. In addition, the white milk intake frequency was significantly higher in middle school students and male students than in high school students and female students(p<0.001). Preference for milk showed a positive correlation with preference for dairy products (r=0.543, P<0.001) and frequency of milk intake(r=0.429, P<0.001). This suggests that those who prefer milk high tend to prefer dairy products and to show high milk intake frequency. In addition, milk intake frequency was in a high positive correlation with dairy product intake frequency(r=0.648, P<0.001).

The purpose of this study was to explore dietary patterns and compare dietary patterns using cluster and factor analysis in Korean adults. This study analyzed data of 4,182 adult populations who aged 30 and more and had all of socio-demographic, anthropometric, and dietary data from 2005 Korean Health and Nutrition Examination Survey. Socio-demographic data was assessed by questionnaire and dietary data from 24-hour recall method was used. For cluster analysis, the percent of energy intake from each food group was used and 4 patterns were identified: "traditional", "bread, fruit & vegetable, milk", "noodle & egg", and "meat, fish, alcohol". The "traditional" pattern group was more likely to be old, less educated, living in a rural area and had higher percentage of energy intake from carbohydrates than other pattern groups. "Meat, fish, alcohol" group was more likely to be male and higher percentage of energy intake from fat. For factor analysis, mean amount of each food group was used and also 4 patterns were identified; "traditional", "modified", "bread, fruit, milk", and "noodle, egg, mushroom". People who showed higher factor score of "traditional" pattern were more likely to be elderly, less educated, and living in a rural area and higher proportion of energy intake from carbohydrates. In conclusion, three dietary patterns defined by cluster and factor analysis separately were similar and all dietary patterns were affected by socio-demographic factors and nutrient profile.

This study was performed to assess the nutrient intake and dietary diversity of Korean children and adolescents using the Korean dietary pattern index developed in previous studies. For this study, 6,462 children and adolescents aged 7~18y who participated in the dietary intake survey (24h recall method) of the 2007~2013 KNHANES were sampled. The food items included in the Korean dietary index were jusik-ryu, guk/tang-ryu, gui/jjim-ryu, namul-ryu, yeomjangchaeso-ryu, jang-ryu and mitbanchan-ryu. All the subjects and both age groups (7~12y, 13~18y) were divided into quartiles. According to the results of this study, the range of the Korean dietary pattern score was 0~58 for all of the subjects and also in the 13~18 age group, and was 0~52 in the 7~12y age group. When the pattern score for each food group was compared across the quartiles of the Korean dietary pattern score, in all the subjects as well as in the 7~12y and 13~18y age groups, the pattern score for jusik-ryu and yeomjangchaeso-ryu was highest in Q1~Q4. or all the food groups, the mean pattern score was highest in Q4. These results suggested that the Korean dietary pattern score is highly associated with jusik-ryu including rice and yeomjangchaeso-ryu including kimchi. Accordingly, it is considered necessary to develop an index that reflects the characteristics of Korean cuisine and, at the same time, assesses the nutritional status and food consumption tendency of Korean children and adolescents.

BACKGROUND/OBJECTIVES: The association between dietary patterns and depression has been reported but the results have been inconsistent. This study was conducted to investigate the association between dietary patterns and depression in middle-aged Korean adults. SUBJECTS/METHODS: The participants were selected from a community-based cohort, a subset of the Korean Genome and Epidemiology Study. Depression was assessed using the Korean version of the Beck Depression Inventory (BDI) and those with a BDI score ${\geq}16$ were defined as having depression. The subjects' food intakes over the year preceding the survey were estimated by using a validated semi-quantitative food frequency questionnaire. Dietary patterns were identified by using factor analysis. Multiple logistic regression was used to assess the association of dietary pattern with depression. RESULTS: Among 3,388 participants, 448 (13.2%) were identified as having depression. We identified two major dietary patterns: 'Healthy' dietary pattern was characterized by high intakes of vegetables, soybeans, mushroom, seaweeds, white fish, shellfish and fruits and a low intake of white rice. 'Unhealthy' dietary pattern was characterized by high intakes of white rice, meats, ramen, noodles, bread and coffee and a low intake of rice with other grains. Compared with subjects in the lowest quartiles, those in the highest quartiles of the healthy dietary pattern had a significantly lower odds ratio (OR = 0.59, 95% CI: 0.42-0.82, P for trend = 0.0037) after adjusting for potential confounders. In contrast, the unhealthy dietary pattern was negatively associated with depression (OR = 1.65, 95% CI: 1.19-2.28, P for trend = 0.0021). CONCLUSION: This results suggest that a healthy dietary pattern (rich in vegetables, soybeans, mushroom, seaweeds, white fish, shellfish, and fruits) is associated with low risk of depression. Whereas an unhealthy dietary pattern (rich in white rice, meats, ramen, noodles, bread, and coffee) is associated with a high risk of depression in middle-aged Korean adults.

According to the data published in 1990s on the intake of dietary fiber(DF) of Korean, DF intake of Korean has been gradually decreasing in the last two decades. Mean daily intake of DF in 1990s is estimated to be in the rage of 17-20g per capita and over seventy five percent of the subjects examined appeared to consume DF less than 20g per day. The major food sources of Df in Korean diet include cereals, vegetables, fruits, seaweeds and seasonings. The present level of DF intake of Korean is lower than the tentatively recommended minimum intake of DF. It is predicted that, if the present trend of change on food consumption pattern is maintained, the gradual increases in the incidence of chronic degenerative diseases will be continuing. Therefore, the beneficial effects of DF on health care and disease control should be emphasized through the nutritional education and high level consumption of DF needs to be strongly recommended in the dietary guideline. In order to raise the daily consumption of DF, more whole grain cereals need to be used as a part of staple and more frequent intake of legumes and seaweeds is required as well as the development of high-fiber diet recipes and natural high-fiber products.
