This study evaluated the validity and reliability of applying a newly developed dish-based, semi-quantitative food frequency questionnaire (FFQ) for Korean diet and cancer research. The subjects in the present study were 288 Korean adults over 30 years of age who had completed two FFQs and four 3-day diet records (DRs) from May 2008 to February 2009. Student's t-tests, Chi-square tests, and Spearman's rank correlation coefficients were used to estimate and compare intakes from different dietary assessment tools. Agreement in quintiles was calculated to validate agreement between the results of the second FFQ (FFQ-2) conducted in February 2009 and the DRs. Median Spearman's correlation coefficients between the intake of nutrients and foods assessed by the FFQ-1 and FFQ-2 were 0.59 and 0.57, respectively, and the coefficients between the intake of nutrients and foods assessed by the FFQ-2 and the DRs were 0.31 and 0.29, respectively. The quintile classifications of same or adjacent quintile for intake of nutrients and foods were 64% and 65%, respectively. Misclassification into opposite quintiles occurred in less than 5% for all dietary factors. Thus this newly-developed, Korean dish-based FFQ demonstrated moderate correspondence with the four 3-day DRs. Its reliability and validity are comparable to those reported in other studies.

The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.

This study was undertaken to examine the knowledge about food culture and intakes of traditional food in Korean and Japanese elementary school students. In 2012 and 2013, a total of 265 students were surveyed, consisting of 73 Korean fifth graders and 192 Japanese sixth graders. The questionnaire comprised of queries on general items, the recognition and sampling of traditional and celebration foods, the knowledge about the partner country's food culture, and the frequency of consuming the partner country's foods. As a result of this study, the frequency of consuming their own country's traditional foods for Korean children (3.1 out of 5.0 points) and Japanese children (3.2 out of 5.0 points) was similar to each other. Japanese children reported to eat Korean foods (2.9 points) more frequently than those of Korean children to eat Japanese foods (2.4 out of 5.0 points) (p<0.001). However, the Korean children reported to have more experience on given typical Japanese foods than Japanese children reported about Korean foods. Further studies are needed for the perception on traditional foods in Korean and Japanese children. The results of this study can be used as a basic data to succeed and develop traditional food cultures.

This study aimed to evaluate dietary behaviors and food allergy status of preschool children in Gwangsan-gu, Gwangju Metropolitan city. The survey included 592 preschool children aged 1-5 years old in 31 childcare facilities. General characteristics, feeding type, complementary feeding, food allergy, dietary behaviors based on the NQ-P questionnaire, and dietary habits of their family were considered. Exclusively breast-fed children was 32.2% of the subjects and the breast feeding duration was 6.5 months. Subjects who had complementary feeding within 6 months was 77.2% and starting time of complementary feeding was 6.1 months. Fifteen percent of the subjects had food allergies and foods that induced allergy were instant foods, eggs, milk and dairy products, nuts, seafood. Food allergy was not related to breast feeding nor complementary feeding. The NQ-P score and its 3 factors including 'balance', 'moderation', and 'environment' were 59.9, 61.1, 56.0, 62.6, respectively. There were positive relations between children's dietary behaviors and family dietary habits such as breakfast eating frequency and meal regularity. As age of children increased, instant food intake increased and breakfast eating frequency decreased. Proper nutrition education is needed to children, their parents, and their care givers at childcare facilities to improve children's dietary behavior and health.

To study the importance of family meals in adolescents, 251 middle school students were surveyed through a questionnaire on their family meal patterns, dietary behaviors, food intake, and life satisfaction. The family meals were defined as "meals with all family members living together" by 62.2% of the students. For the frequency of family meals, 42.2% of the students replied having family meals "More than once a day". A common reason for the difficulty in having a family meal was a "lack of time" (73.3% of the students). Students tended to respond that they would be most fond in having meals with entire family members with traditional Korean food. Having more frequent family meals was found to benefit both individual and familial dietary behavior. In terms of food intake according to the frequency of family meals, the group having frequent family meals consumed significantly more rice, tofu, legumes, meats, fishes, eggs, green vegetables, seaweeds, fruits, milk, and milk products. This indicates that students can achieve a balanced diet through family meals. In terms of emotional status, the group having more frequent family meals showed a higher satisfaction with their daily life, health, nutritional status, and care from their relatives. In terms of personal mental status, the group having more frequent family meals was also found to be more effective at controlling undesirable emotions such as loneliness, indignation, and lethargy. As a result of this study, students in the group having more frequent family meals were found to have a positive dietary behavior, a balanced nutrition, a higher life satisfaction, and a more stable mental status. This result is useful as nutritional and educational information in schools to impress upon the public the importance of family meals for adolescents.

This study was designed to compare the prevalence rate of obesity, food attitude, food frequency and food habits between children in Kangnung and Seoul areas. 1,005 children aged 9-12 were included in this study. They were composed of 343 children living in Kangnung from one elementary school, and 662 children in Seoul from two elementary schools. The body weight, height, waist and hip circumferences of children were measured and food frequency scores of Korean and Western foods were examined by questionnaire. And questionnaires about food attitude, food habits and life style were administered to the mother of each child. There was no significant difference in body weight and obesity index among three groups(one school of Kangnung area and two schools of Seoul area). The male children\`s prevalence rates of obesity in Kangnung and two schools(A, B) of Seoul were 10.3%, 10.3% and 7.3%, respectively. Female children\`s prevalence rate were 5.4%, 4.7%, and 6.3%, respectively. Children in Seoul turned out to more frequently eat such Korean foods like pulkogi, kalbi and fried rice and such western foods like butter, margarine, hamburger, pizza, and fried chicken. Children in Seoul had more tendency to eat regularly and spent less time in sleeping and watching TV and more time in exercise than the respondents in Kangnung. The obesity index of parents had a significantly positive correlation with that of children. These results suggest that children in Seoul have tendency to eat high-energy food frequently and to have more energy expenditure than children in Kangnung. In conclusion, further studies on the evaluation of energy intake and energy expenditure of obese and normal children different in area should be conducted.

This study was performed to determine the effect of carotenoid-rich food consumption and smoking on the lipid peroxidation and antioxidant status in human. The subjects consisted of the health 210 middle-aged adults who visited health care center in the Inha University hospital. The blood and urine samples of the subjects were taken to analyze serum lipid profiles, plasma TBARS, total antioxidant status (TAS) and urinary 8-isoprostanes concentration. The anthropometric indices of the subjects were measured. The nutritional intake and the frequency of carotenoid-rich food consumption was determined by semi-quantitative food frequency questionnaire survey. HDL-cholesterol level of the smoking subjects was significantly lower than that of the non-smoking subjects in men. In the analysis of the carotenoid-rich food consumption, the frequency of pepper and tomato consumption of the non-smoking subjects was significantly higher than that of the smoking subjects in men. In women, the Sequency of pear and peach consumption of the non-smoking subjects was significantly higher than that of the smoking subjects. HDL-cholesterol level of the high carotenoid rich food consumption group was significantly higher than that of medium and low group in women. TAS of the high carotenoid rich food consumption group was significantly higher than that of medium and low group. In conclusion, carotenoid intakes seemed to be effective to reduce lipid peroxidation and increase antioxidant status in the body. The frequency of the carotenoid-rich food consumption seemed to be lower in the smokers than in the non-smokers. However, further researches consisted of large-scaled and randomized clinical trials are required to determine whether carotenoids have any other beneficial effect in human.
