In this study, 342 grade 4-6 elementary school students in Gyeonggi-do were recruited to determine their readiness to change food safety behavior and to compare their food safety knowledge and practices by the stages of change. The subjects were divided into three stages of change; the percentage of stage 1 (precontemplation) was 10.1%, the percentage of stage 2 (contemplation and preparation) was 62.4%, and that of stage 3 (action and maintenance) was 27.5%. Food safety knowledge scores in stage 3 (4.55) or stage 2 (4.50) children were significantly higher than those in stage 1 children (4.17) (P < 0.05). The two food safety behavior items "hand washing practice" and "avoidance of harmful food" were significantly different among the three groups (P < 0.05). Stages of change were significantly and positively correlated with food safety knowledge and practice. Age was significantly and negatively correlated with the total food safety behavior score (r = -0.142, P < 0.05). The most influential factor on the stage of change was a mother's instruction about food safety (P < 0.01).

In this study, we investigated protection motivation and behavioral intention to prevent serious illnesses related to excessive sodium intake among the university students in Gyeongnam and Busan. Within the protection motivation theory (PMT) framework, a survey questionnaire was developed to measure participants' perceptions on the severity of and the vulnerability to the threat of serious diseases due to the high sodium intake as well as the effectiveness of preventive measures (response efficacy), and the ability to perform them (self-efficacy) along with their willingness to follow recommendations (behavioral intention). Data was collected in June 2015. Study participants were divided into either low (n=117) or high (n=177) sodium intake behavior groups based on their current behaviors. Exploratory factor analysis was performed to measure construct validity and Cronbach's alpha was calculated to check reliability of measurement items. The high sodium intake behavior group perceived higher vulnerability than the low sodium intake behavior group among four PMT factors. Differences of the other three factors were not significant between the two groups. The results of hierarchical regression analysis indicated that self-efficacy and response efficacy affected behavioral intention of high sodium intake behavior among students. Hence, development of strategies to increase self-efficacy and response efficacy are strongly recommended.

In this study, the eating out behavior and recognition of salinity in restaurant food in Jecheon area were examined. Demographic characteristics of the subjects, eating out behavior and perception of salinity in food purchased in restaurants were surveyed. Also salinity of the high Na-containing menus were measured using salimeter. Exactly 51.6% of the study subjects usually ate out more than one to two times per week. A large percentage (88.6%) of the subjects mentioned that they ate more than half the amount of liquid in their dishes. The study participants recognized that the salt concentrations of stews, soups and noodles in their orders were high. JJamppong was recognized as the most salty among nine kinds of eating out menus, whereas mulnaengmyeon was the least. Although the recognized salt concentration of mulnaengmyeon was relatively low, this dish had the highest salinity out of nine eating out menus. Relative salinities of eating out menus were higher than absolute salinity mostly except yukgaejang. It is necessary to supply exact nutrition information and widely implement nutrition labeling. Furthermore, consumers should personally be careful to limit consuming food with high sodium levels when dining at restaurants and eat less liquid in dishes.

Objectives: This study was conducted to assess the eating behavior, growth, and dietary practices of children aged 3~5 years living in the Seoul and Gyeonggi Provinces. Methods: Self-administered questionnaires were completed by 237 mothers of preschool children between April and June 2018. Z-scores for weight-for-age, height-for-age, and BMI-for-age were calculated to determine the children's growth status. Dietary practices were evaluated using the nutrition quotient for Korean preschoolers (NQ-P). Results: In our study, 29.5% of children were in the eating-small-amounts group, 46.8% of children were in the neophobic behavior group, and 61.2% of children were in the refusal-of-specific food group. Specific foods found to have a high frequency of rejection are listed in descending order as follows: shellfish, soy, mushroom, shrimp, vegetables, milk, eggs, yogurt, seaweed, meat, fruits, and fish. The eating-small-amounts group had lower Z-scores for weight-for-age, height-for-age, and BMI-for-age than the non-picky eaters' group. Compared to the non-picky eaters' group, the eating-small-amounts group of picky eaters had lower scores on the moderation and environment items of the NQ-P, the neophobic behavior group had lower scores on the balance and environment items of the NQ-P, and the refusal-of-specific food group had lower scores on the balance, moderation, and environment items of the NQ-P. Conclusions: Children classified with picky eating behavior had lower growth and development, lower diet diversity, less balanced food intake, and had greater difficulty in abstaining from eating unhealthy foods than non-picky eaters. Therefore, a lot of patience and intensive efforts are needed to encourage children to encounter, experience, and accept unfamiliar food. It is more effective to provide eating behavior guidance by gently encouraging children, than by being strict and forceful. Besides, since the eating behavior of children is influenced maximally by the dietary lifestyle at their homes, it is important to ensure that a healthy dietary lifestyle is maintained at home.

Previously, we analyzed for nutrition knowledge and the use of nutrition knowledge in the everyday lives of students in order to develop nutrition education programs that focus on desirable behavior change. From this, we found that female students desired to participate in nutrition education more than male students, and regarding their concerns for nutrition education, 73.2% of the females and 50.0% of the males displayed interest in 'obesity and the regulation of body weight'. Therefore, this study showed female students give more attention to the obesity and the regulation of body weight than male students(p=.000<.001). In addition, female students had higher interests($8.63{\pm}1.67$) than male students ($7.45{\pm}2.03$) in nutrition knowledge(p=.000<.001). By investigating the use of nutrition knowledge in everyday life, our research indicated that the actual use of nutrition knowledge was less. To encourage students to persue dietary lives addressing the concerns confirmed above, the following needed to occur. 1) Provide them nutrition information for the main processed foodstuffs encountered when dining out(breads, cakes, cookies, and carbonated beverage). 2) Teach them to read food nutrition labels. 3) Help them find a lifestyle connection through lasting self-management methods and the generation of social support. Accordingly, this required developing effective and practical nutrition education programs that considered regional characteristics and gender differences. The most important factors considered during nutrition education program development were the need for motivation and ongoing education by stage of change, rather than temporal education through specific problem analysis, in order that those being educated may bring about a change of behavior by themselves. Therefore, from this study, we have suggested the use of multilateral operating strategies for successful nutrition education. In addition the phase model of behavior change should be applied. Our programs were aimed at self owned nutritional management so that students could master their own methods for acquiring skills and enjoying dietary life. The research may be summed up as follows. First, the purpose of education at the recognition stage of change was to attempt motivation for nutrition improvement, by analyzing the problems such as food buying habit and the main purchasing viewpoints when dining out. Second, the purpose of education at the action stage of change was to help students acquire of concrete methods for behavior modification by linking the program to their home as well as to teachers with various activities that suited the situation at school. This was done by analyzing the processes and decisions pertaining to dining out the main processed foodstuffs and principal components, etc. through data and experimental practice. Third, the purpose of education for changing of habits and values, or the maintenance stage, was to investigate the various reasons that undesirable behaviors were induced, and then determine a lasting self-management method as well as how to generate social support. If the nutrition education program developed in this study is utilized on site, someone in the primary role as the nutrition educator and trained specifically in nutrition, can help induce the health promotion in the community as well as lasting dietary management, by executing a link with families in parallel with educating teaching staff and students' parents. In addition, this program can playa role in the government policies related to the health promotion for our youth who are the foundation of our nation and who can enhance our national competitive power.

This study was a correlation study to analyze the effects of smartphone usage time on food choice perceptions and behavior in middle school students in Seoul areas. The subjects to be surveyed were middle school students attending junior high schools in Mapo-gu, Seoul. A total of 133, 102, and 102 students were in the first second, and third grades, respectively. The usage time of smartphones was the weekday and weekend usage time except for the call function. Food choice perception and its behavior as dietary habits were constructed referring to previous research and food balance wheels data for the correct dietary habits of the Ministry of Health & Welfare and Korean Nutrition Society. The food choice behavior was categorized into non-recommended food and recommended food. The results are summarized as follows. First, the longer the time spent on smartphones, the less favorable the perception of correct food choices. Second, the higher the dependence on smartphones, the less favorable the perception of correct food choices. Third, the correct perception of food choices has been shown to reduce food choices, known as non-recommended foods. In addition, proper perception of food choices has been shown to increase the choice of recommended foods. In conclusion, the usage time and reliance of smartphones of middle school students was found to affect the food choice behavior by lowering the perception of correct food choices. This research is expected to form the basis for the development of programs and educational materials that can be of assistance to adolescents who are experiencing difficulties.

The principal objective of this study was to determine the importance of obesity management nutrition programs for obese male workers after performing a 10-week nutrition program and to compare changes in the obesity index, health behavior, meal intake, and blood constituents. The study subjects included 44 individuals, all without chronic disease. After the program, the weight, body mass index (BMI), body fat percentage, and waist-hip ratio (WHR) of the subjects dropped. Dietary life behavior scores increased. In particular, more than 30% increases were detected in self-control of surfeit, control of eating speed, temperance, and regular exercise items. Total caloric intake and average drinking intake dropped. Though insignificant, systolic pressure, total cholesterol, LDL-cholesterol, and sGPT all dropped as compared to the levels measured prior to the program. Fasting blood sucrose, triglyceride, $\gamma$-GTP, and atherogenic index dropped significantly. HDL-cholesterol, though insignificant, increased. As the result of examining correlations between the subjects' health life behavior, caloric intake, and improvement in obesity, we noted a significant correlation between self-control of surfeit and temperance in the health life behavior item, along with significant correlations among total calorie intake, surfeit percentage, and daily average drinking intake. These results demonstrated that nutrition program for obese workers performed at the Community Health Center had the effect of reducing obesity, improving health behavior, and improving clinical levels. Thus, it is advisable that obesity management programs be achieved, linking the center of local societies' health promotion projects, community health centers, and workplaces, and various programs should be developed to maintain and continue changes in workers' behaviors, such that the positive effects of improvement in obesity could be maintained, even after the program.
