The purpose of this study is to compare the nutrition knowledge, dietary behavior and food frequency according to the gender and weight control attempt among middle school students in Seoul and Gyunggi-do, Korea. The subjects were divided into three groups, one with experience in attempting to lose their weight, one with experience in attempting to gain their weight and one with no experience in attempting to control their weight. Nutrition knowledge level of girls was higher than that of boys (p<0.01), but there were no significant difference according to weight control attempt. As for the scores of dietary behavior, there were no significant differences by gender but according to weight control attempt, the scores of dietary behavior of the weight loss attempt group were higher than those of the other attempt groups (p<0.01). In the food intake frequency, there were significant differences according to weight control attempt (p<0.05, p<0.01).

This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9$\pm$1.8mg which was 49$\%$of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28$\pm$0.16mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.

Objectives : This study is to suggest a kind of guide line of dietary therapy in allergic diseases. Methods : We investigated frequency, symptoms and implicating foods of food allergy, and experience, methods, periods, results and necessity of dietary therapy of 49 patients with allergic diseases by using self-report questionnaires. The data were analyzed by SPSS／PC+ program using frequency, Chi-square test(p〈0.05) and Pearson correlation coefficient(p〈0.01). Results : 1. The frequency of food allergy was 49% and skin symptoms were the most common. 2. The most implicating foods were chicken, flour, milk, pork and egg in order. 3. 36.7% of patients had experienced dietary therapy and 47.4% of them had stated mild improvement. 4. Over 80% of patients perceived necessity of dietary therapy and there is significant correlation between necessity of dietary therapy and sum of food allergens(r=368). Conclusions : Dietary therapy is recommended as supplementary therapy in allergic diseases and it needs to be established based on the real conditions and Korean Oriental medical theory.

Purpose: This study aimed to investigate the association between steamed food intake and risk of metabolic syndrome (MetS) in Korean females. Methods: Using Ansan/Ansung data of Korean Genome and Epidemiology Study, general characteristics, nutritional intake and biochemical and anthropometric markers of a total of 4,056 females aged 40 to 69 years were analyzed. MetS was defined following National Cholesterol Education Program Adult Treatment Panel III with some minor modifications. Logistic regression models were established to present the association between steamed food intake and the risk of MetS. Levels of food and nutrient intake by the frequency of steamed food intake and MetS phenotype were analyzed using general linear models. Results: A total of 38.4% of females had MetS. Among them, 24.9% of females with MetS had steamed food more than 1-3 times per week, which reduced the risk for MetS by about 25% (95% confidence interval [CI], 0.650-0.865). However, such association was not evident when various lifestyle factors were considered in statistical models. In rural residents, the benefit of having more steamed food was observed (adjusted odds ratio: 0.747; 95% CI, 0.583-0.958). The frequency of steamed food intake was associated with various food and nutritional intakes. However, trends in those did not differ by MetS phenotype. Conclusion: Having steamed food more than 1-3 times per week may reduce the risk of MetS compared to those who had less steamed food in Korean females. This protective effect of steamed food intake may differ by lifestyle and environmental factors. Although a clear difference in food and nutritional intake was not observed in this study, steaming could be an effective cooking method for a healthy diet for disease prevention and management.

This study was conducted to evaluate the risk of overweight and obesity in adolescents consuming snacks frequently from 2007~2009, Korean National Health and Nutrition Examination Survey (KNHANES). The subjects (12~14 years: n=523; 15~18 years: n=614) were presented with food frequency questionnaires, and they were classified according to their gender and frequency of snack consumption. In the age group of 12~14 years, boys and girls (boys OR: 1.11, 95% CI: 0.52~2.39, girls OR: 12.45, 95% CI: 2.26~68.51) who consumed yogurt frequently had a higher risk of overweight and obesity at the highest quartile frequency compared with the lowest quartile after adjustments for multiple confounding factors, including age, physical activity, frequency of eating out and snack consumption, and energy intake. In the age group of 15~18 years, girls (OR: 1.01, 95% CI: 0.34~2.99) consuming fried foods had a higher risk of overweight and obesity at the highest quartile frequency compared with the lowest quartile after adjustments for multiple confounding factors, including age, physical activity, frequency of eating out and snack consumption, and energy intake. Thus, we conclude that frequent consumption of yogurt and fried foods increases the risk of overweight and obesity in adolescents. These findings suggest that the risk of overweight and obesity is associated with the frequency of snack consumption.

Validation of a food frequency questionnaire (FFQ) utilising a short-term measurement method is challenging when the reference method does not accurately reflect the usual food intake. In addition, food group intake that is not consumed on daily basis is more critical when episodically consumed foods are related and compared. To overcome these challenges, several statistical approaches have been developed to determine usual food intake distributions. The Multiple Source Method (MSM) can calculate the usual food intake by combining the frequency questions of an FFQ with the short-term food intake amount data. In this study, we applied the MSM to estimate the usual food group intake and evaluate the validity of an FFQ with a group of 333 Korean children (aged 3-6 y) who completed two 24-hour recalls (24HR) and one FFQ in 2010. After adjusting the data using the MSM procedure, the true rate of non-consumption for all food groups was less than 1% except for the beans group. The median Spearman correlation coefficients against FFQ of the mean of 2-d 24HRs data and the MSM-adjusted data were 0.20 (range: 0.11 to 0.40) and 0.35 (range: 0.14 to 0.60), respectively. The weighted kappa values against FFQ ranged from 0.08 to 0.25 for the mean of 2-d 24HRs data and from 0.10 to 0.41 for the MSM-adjusted data. For most food groups, the MSM-adjusted data showed relatively stronger correlations against FFQ than raw 2-d 24HRs data, from 0.03 (beverages) to 0.34 (mushrooms). The results of this study indicated that the application of the MSM, which was a better estimate of the usual intake, could be worth considering in FFQ validation studies among Korean children.

Korean food habits, dietary behaviors and perception of food were compared according to gender and age. The subjects were composed of 274 males and 315 females. According to age, the age group of 10s was 26.3%, 20s 24.6%, 30s 16.8%, 40s 18.7%, and 50s and over 13.6%, respectively. The majority (65.2%) of all age groups except the 20s took meals 3 times a day and the ratio 20s eating twice a day was higher than other age groups. All age groups took cooked rice(bap) two or three times a day and the 20s group took smaller amount than other age groups did. The younger age groups of 10s and 20s took larger amount of processed food. The older age groups appeared to have higher frequency of eating fish, bean, vegetable, Kimchi, laver.brown seaweed, soybean oil, sesame oil, coffee, tea, and rice cake(ddhuk). The younger groups have the higher frequency of eating ramyeon, corn flake, milk, milk-processed food, butterㆍmargarine, ham.sausage, carbonated drink candyㆍchocolate, hamburger, and pizza. All age groups perceived cooked rice(bap), meat, fish, egg, vegetable, fruit, and Kimchi to be the delicious, excellent and healthy food. According to the above results, age groups of 30s and over had relatively better food habits compared with those of younger groups. On the other hand, the groups of 10s and 20s had meals irregularly, showed a high ratio of skipping meals, and took processed food much. These results raised a concern of their nutritional imbalance in the future. Therefore, the correct nutritional education must be conducted to make these age groups have a healthy food habits.

This study examined the dietary behaviors and dietary quality of high school students according to the number of times they skipped breakfast. A total of 474 high school students (225 boys and 249 girls) residing in Incheon participated in this survey. The subjects were divided into the three groups according to the frequency of eating breakfast; Regualr (eating breakfast everyday, n=226), Irregualar (eating breakfast 1~6 times/week, n=143, and Skipping (skipping breakfast everyday, n=105). The dietary quality was assessed using a nutrient quotient for adolescents (NQ-A). A higher monthly allowance and a higher rate of working mothers were significantly associated with a higher frequency of skipping breakfast. A higher intake frequency of processed beverages, and street food was significantly associated with a higher frequency of skipping breakfast. Students who had a higher rate of breakfast skipping had significantly lower intake frequency of fruits, white milk, bean and bean products, and fish. The high frequency of skipping breakfast among high school students was associated with lower dietary quality, as illustrated by the low total NQ-A score and sub group score including balance, environment, and practice. This information can inform efforts to provide nutrition education program to promote breakfast consumption and guidelines to students who skipped breakfast frequently.

The purpose of this study was to investigate the relations of breakfast skipping and dietary habits according to breakfast intake frequency. Subjects were 5th and 6th graders of elementary school(n=423) in Gyeonggi area. As a result of analyzing the breakfast intake frequency, 'Having everyday' showed the highest 63.4%, followed by '4~6 times' 16.5%, '2~3 times' 13.5% and '0~1 times' 6.6%. As a result of analyzing the relations between mother and child in the breakfast intake frequency, it showed that the more mothers skipped breakfast, the more their children skipped it. For the reason of skipping breakfast, 'To be in time for school' showed the highest percentage. As a result of analyzing the perception of awareness for the importance of nutrition and dietary habit according to the breakfast intake frequency, there was a statistically significant difference in breakfast intake, dietary habits, selection and intake of proper food, disease and health problem according to the breakfast intake frequency. As a result of study, it is necessary that nutrition education should not be limited to children but expanded to their parents in order to increase the efficiency and effectiveness of nutrition education between school and home.
