Objectives: This study investigated the relevance of dietary behavior and oral management for oral heath in adults to extend the recognition of the importance of food intake in oral health and to provide basic information for oral health management. Methods: A survey and clinical assessment were conducted for 119 adults over 20 years of age. The chi-square test and logistic regression analysis were carried out using SPSS Statistics 20.0. Results: Gingivitis was influenced less when ham and sausage in the sub-area of meat, fish, egg, and bean were consumed once a week rather than the cases when consumed rarely (3.47 times) or when consumed two times or more a week (7.87 times) (p<0.05). Periodontitis was influenced more in the groups of 30s and 40s age than in that of over 50 years of age (14.97 times, 7.73 times) and in the group without drinking experience than in group with that (4.17 times) (p<0.05). Conclusions: The results verified the close relationship between food intake frequency and oral health in patients with periodontitis and gingivitis. Thus, it would be necessary to study the relationship between dietary behavior and oral health continuously.

Objectives: The purpose of the study was to investigate the relationship between health behavior and oral symptoms in Korean adolescents. Methods: The subjects were 72,060 adolescents who were selected from the web-based survey of the 10th (2014) Korean Youth Risk Behavior of Korean Center for Disease Control. Data were analyzed by PASW statistics 18.0. A web-based self-reported questionnaire was completed by 74,167 middle and high school students. The subjects consisted of 36,470 boy students (52.2%) and 35,590 girl students (47.8%) from 400 middle schools and 400 high schools. Results: Multiple logistic regression analysis revealed that experience of oral symptoms were related with sex, age, academic achievement, economic status, alcohol drinking, moderate physical activity, muscular strength exercises, walking, fruit consumption, milk consumption, fast food consumption, snack consumption, daily tooth brushing frequency, use of fluoride toothpaste, school based oral health education, dental sealant and dental scaling. Conclusions: There were close relationship between heath behavior, oral health behavior, and experience of oral symptoms. To improve the health promotion for the adolescents, oral health program development and primary prevention strategy must be established.

Objectives : This study was conducted to evaluate the public's awareness of the importance of hand washing and to compare perceptions on the habit of hand washing with actual hand washing behavior. Methods : Data were collected by observing 2,800 participants washing their hands after using public restrooms in seven cities nationwide and by surveying 1,000 respondents (age > 14 years) through telephone interviews using a structured questionnaire. Results : Although 94% of the survey respondents claimed to mostly or always wash their hands after using public restrooms, only 63.4% of the observed participants did wash their hands after using public restrooms. Significant factors related to increased adherence to hand washing were female gender, approximate ages of 20 to 39 years by their appearance, and the presence of other people from the observation. About 79% of the survey respondents always washed their hands after using bathrooms at home, 73% washed their hands before handling food, and 67% washed their hands upon returning to their home. However, 93.2% and 86.3% of the survey respondents did not wash their hands after coughing or sneezing and after handling money, respectively. Although most of the survey respondents (77.6%) were aware that hand washing is helpful in preventing communicable diseases, 39.6% of the survey respondents did not do so because they were 'not accustomed' to washing their hands and 30.2% thought that washing their hands is 'annoying'. Conclusions : This is the first comprehensive report on hand washing behavior and awareness of the general population in Korea. The result of this study in terms of individual behavior and awareness of hand washing are comparable with similar studies conducted in other countries. However adherence to hand washing is still low and needs to be increased. The results of this study can be used as a baseline in setting up strategies and activities to promote adherence to hand washing.

BACKGROUND/OBJECTIVES: The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS: This study is based on the 1998-2012 KNHNES. Analysis data on 54,700 subjects aged 19 years and older were obtained from health behavior interviews and the 24-hour dietary recall method. RESULTS: Daily kimchi consumption and portion size of kimchi decreased significantly from 1998 to 2012 (adjusted P for trend < 0.0001). Meanwhile, daily consumption of both non-salted vegetable and fruit with and without kimchi did not significantly change between 1998 and 2012. Reduced consumption of kimchi, non-salted vegetable, and fruit was observed for both genders as well as daily meal episodes and cooking locations. Male and female subjects with insufficient non-salted vegetable and fruit intake were increased 1.4 times and 1.3 times, respectively, in 2012 than 1998. All subjects consumed at least 400 g/day of non-salted vegetable, fruit, and kimchi in each survey year, although they consumed insufficient amounts (< 400 g/day) of non-salted vegetable and fruit without kimchi. CONCLUSIONS: Since Koreans generally consume high amounts of fermented vegetables, including kimchi, total vegetables and fruit. Consumption of these foods by the Korean adult population reached 400 g, which is the recommended intake of the WCRF/AICR. Based on this result, it is necessary to promote consumption of kimchi in the Korean population and research the development of low sodium kimchi in the future.

The purpose of this study was to measure the nutrition knowledge, dietary attitude, eating behavior, physical ability and locomotion of 5-year-old-children, and thereby to provide the fundamental information necessary to develop a nutritionrelated physical education program. A survey was performed on 143 5-years-old boys and 113 girls. The results were as follows. The average score in the nutrition knowledge item, was 7.22 out of a possible 10 points; in the dietary attitude item, 32.46 out of 50 points; in the eating behavior item, 26.67 out of 40 points. According to body measurement, there was a significant difference in height by gender (p<0.05), Significant differences in muscle mass and basal metabolic rate were also observed by gender (p<0.001). Gender also influenced the flexibility and reflexibility (p<0.001), with significant difference in balance of the right side (p<0.01). Although this study was limited by its cross-sectional study design, the body muscle (p<0.05) and basal metabolic rate (p<0.05) were observed to have a positive relation with nutritional knowledge. In addition, there was a significant positive correlation between nutritional knowledge and dietary attitude (p<0.01). According to the results, it is necessary to develop a long-term and systematic program with the combination of nutrition and physical education to develop correct dietary habits and for the balanced growth of children.

The purpose of this study was to examine the use of social commerce restaurant products by college students according to demographic characteristics and eating out behavior. The questionnaire for the survey was distributed to 450 college students, who have experiences of purchasing a restaurant product on social commerce, with 286 responses used for analysis. From the result, college students frequently use smart phones and SNS for making such purchases. While the awareness of social commerce was high, they sometimes visited the websites and purchased products. The awareness and purchase experience of Coupang and Ticket Monster turned out to be the highest. The most frequently purchased product was restaurant discount coupons, followed by fashion/accessories, movie or concert tickets, food products, and beauty shop discount coupons. The discount rate was mostly 30 to 40% on average. The most significantly considered matter in purchasing products and services was product quality, followed by discount rate and consumer review. The respondents ate out at least 3 to 5 times a week, spent $100,000{\leq}200,000$ won, and were generally satisfied with the restaurant products from social commerce sites. The main satisfaction reason was price, whereas the dissatisfaction reason was false and puffy advertising. Service quality improvement and variety of category were the most necessary factors for improvement. Among the demographic characteristics, there was a difference in purchase expenditure of social commerce restaurant products, as well as purpose, companion, time used and word-of-mouth experience according to gender. According to grade, there was a difference in purchase expenditure, companion, area of use and impulsive purchase. Among the eating out behavior, there was a difference in purpose, companion and word-of-mouth experience according to the eating out frequency. Meanwhile, there was a difference in purchase expenditure, companion, time used, word-of-mouth experience and tool according to the eating out cost.

This report includes basic data on nutrition education for Chinese adolescents living in Korea. A total of 183 Chinese adolescents living in Incheon participated in the survey. Body composition was analyzed by the Inbody 4.0., and questionnaires on personal dietary behavior were administrated. When compared with the body measure indices of Korean adolescents, we found that height was similar, but weight greater ($5{\sim}12 kg$) among the participants. Regarding obesity, 30.0% of all students were obese (BMI>25), especially the high school boys (42.0%). But in the case of middle school boys, the rates of obesity and under weight (BMI<18.5) were the same (both of them at 22.9%). The average WHR (Waist Hip Ratio) of the female high school group (0.9) was over the normal range. The average percent body fat for each group was also over the normal range. The percentage of students having breakfast everyday was 52.2%, and the rate of skipping breakfast was 25.0%. In the obesity group, the rate of skipping breakfast was remarkably high (P<0.05). Because lunch service was not available at the schools, a lunch box from home was the most popular pattern (43.1 %), but eating out was also popular at 36.6%. For the male high school students, the eating out rate was 62.8%. Since many have-lived in Korea for a few generations, the students' eating practices were much closer to the Korean pattern. For their ordinary meal pattern, 96.0% of the students included Korean foods. however, for New Years Day, the rate of having Gyo-Ja was 75.2%, and having Wol-Byung at Choo-seok was 78.6%, showing that the Chinese tradition still remains. In the case of food preferences, the percentage having Kimchi everyday was 62.1 %, but those drinking green tea was 13.1 %. For cold drinks, the rate for drinking them more than twice per week was 71.6%. The most preferred cooking method was frying with oil (50.6%). Among the students who had visited China (or Taiwan), the rate for 'bad food familiarity' was 37.0%, and the rate for 'did not know Chinese traditional course menus' was 71.3%. As a result of combining eating practices from both China and Korea, and the absence of lunch service in Chinese schools, students are showing bad dietary behaviors. therefore, it is necessary to provide proper nutrition education and a system for lunch service in Chinese schools.

Objectives: This study was performed to investigate hygienic behavior of food handlers and general population focusing on awareness of hand-washing and the microbial load of their hands. Methods: A questionnaire survey and microbiological analysis were carried out for sixty-four people each. Samples for microbiological analysis were collected through the glove-juice method from the hands, and were analyzed for the presence of aerobic plate counts, total coliform, fecal coliform, Escherichia coli, Staphylococcus aureus, and Salmonella spp. according to the Food Code of Korea. Results: In the survey, significant differences between the food handlers and general population (p < 0.01) were found in hand-washing frequency, duration, use of hand-washing agents, washing parts of hands, hand-drying method, and method of turning off water. In eight different situations among the ten particular situations in their daily life, more food handlers responded to wash their hands than general population (p < 0.05). Bacterial load on hands with general population was consistently higher than with food handlers (p < 0.05), however, percentages of positive hands of S. aureus and Salmonella spp. were not. Conclusions: Poor hand hygiene practices were indicated by the positive results for E. coli, S. aureus, and Salmonella spp. on the hands of some respondents in both groups. This study reveals that there is the need for programs or campaigns to increase hand-washing practices of both groups.

A Survey was conducted to identify patrcis' eating behavior at the buffet styled restaurant during dinner time. The average frequency of taking food was 4.1±0.9 and this was statistically significant by age group. The frequency of taking food after satiety was 1.2±0.8. From the menu, 15 seafood items were the most popular which were chosen more than twice. The average of consumed food items was 24.9±8.9 out of 198. The average seafood items which were chosen by each individual was 5.8, desert items was 4.5, salad items with dressing was 4.2. The total weight of the consumed food was 954±365.1g. Mostly gruel, soup and saled chosen the first time. Alcholic beverages and drinks were chosen also first time. Seafood was chosen the 1.2 times and meat was chosen the first, second, and third time. Rice and soup. bread and noodles were chosen the second and third time. Desert was chosen the third time. The consumption of calories and nutrients were compared with the Korean Recommended Dietary Allowances. The average consumption of calories was 49.6% Korean RDAs, protein 71.4%, vitamin A 65.0%, thiamin 74.3%, riboflavin 71.8%, niacin 89.8%, ascorbic acid 72.7%, iron 68.1%, and calcium 108.3%. In one meal, the data shows over eating. The caloric consumption of desert was 275.5Kcal and seafood was 174.1Kcal. The protein consumption of seafood was 23.5g and meat was 7.5g. According to this research, customers have a lot of good chances to be exposed to the variety of food. This is desirable to correct the food habits with a experience. On the other hand, excessive food consumption is a problem. Therefore we suggest the provision of nutrition information about desirable order of eating a meal and the health problems due to overeating. We expect other research of nutritional evaluation in a meal in the different foodservice systems to be made in the future.

This study was conducted to investigate the dietary pattern of children with unbalanced diet in school feeding. Children who eat only what they like among elementary school students were selected for this survey. The general characteristics, nutrition knowledge, eating behavior, food intake frequencies and food preferences of the subjects were investigated compared with control group. The subjects were consisted of a total of 160 children : 92 male students(unbalanced-diet group, 46; control group, 46), and 68 female students(unbalanced-diet group, 34; control group, 34). There was no significant difference in nutrition knowledge between the unbalanced-diet group and the control group. Dietary behavior of control group turned out to be more desirable than that of the unbalanced-diet group. In addition, 68.7% of the unbalanced-diet group and 13.8% of the control group hated to eat vegetables. The result of food intake frequency indicates that the control group turned out to be higher in their intake of fish, cereals, vegetables, seaweeds, fats & oils and Kimchi compared with unbalanced-diet group. Intake frequency of minerals and vitamins of the control group was higher than that of the unbalanced-diet group. On the other hand, the unbalanced-diet group turned out to be higher in sugar intake. Children showed the greatest preference of fruits. The unbalanced group turned out to prefer sugar and beverages more than the control group. These results suggest that the desirable dietary habits of children should be formed with the help of nutrition education designed for behavior modification.
