Purpose: The purpose of this study is to identify factors affecting fruit consumption behavior by application of the Theory of Planned Behavior. In addition, this study examined the moderating effect of a fruit eating habit. Methods: A total of 734 consumers who have ever purchased fruit participated in this study. Results: Results of this study showed that attitudes toward fruit intake, social norms, and perceived behavioral control had significant impacts on the level of fruit intake. Fruit eating habit that showed high correlation with eating behavior was also included in the model identifying factors having an influence on fruit intake. Attitudes toward fruit intake, social norms, and perceived behavioral control had a positive influence on intention to intake fruit. Fruit eating habits played a moderating role in the relationships between intention to intake fruit and real fruit intake. Conclusion: Increasing positive attitudes toward fruit intake, social norms, and perceived behavioral control would be helpful in increasing the amount of fruit intake.

The purpose of this study was to compare the mineral and vitamin intake according to the stage of change in fruit and vegetable intake. The subjects consisted of 256 students, 122 males and 134 females, who are fourth, fifth and sixth grade in an elementary school located in Yeongi-Gun, Chungnam province. The dietary intake wasexamined by 24 hr dietary recall for 1 day and by food record for 2 days from April 19 to May 01, 2007. Stage of change of intake of fruits and vegetables of the students was categorized into three groups: precontemplation, contemplation and preparation, and action. The subjects at the stage of action took kimchi and vegetables more frequently, and also took more vitamin C as well. But the subjects at other two stages did not show any difference in the intake of any food group and nutrients. Percentage of the male subjects who took less than EAR did not show any significant difference by stage of change in all the nutrients. However, there was gradual decrease in the percentage of female taking less than EAR of vitamin C and vitamin B2. The result concludes that vitamin C intake significantly increase gradually as the stages of behavioral change of fruit and vegetable intake proceed although almost all vitamins and minerals tended to increase.

The aim of this study was to investigate the associations among the food choice motives, attitude to the traditional fermented food, and traditional fermented food consumption behavior in adolescents. Using a web-based self-completion questionnaire, food choice motives, attitude to the traditional fermented food, and frequency of traditional fermented food consumption were examined in 319 high school students in Seoul. As follows are the results of this study; first, food choice motives were emerged by seven factors, and labeled as good food, healing, convenience, weight control, familiarity, price, and health. Attitude to the traditional fermented food and consumption behavior of traditional fermented food were emerged as independent factor, respectively. Second, food choice motives had the significant effect on the attitude to the traditional fermented food(p<.05). Among them, price had the strongest effect(${\beta}$=.235), followed by healing(${\beta}$=.190), health(${\beta}$=.175), and convenience(${\beta}$=.126). Third, the consumption behavior of traditional fermented food was strongly influenced by the attitude to the traditional fermented food(${\beta}$=.549). Finally, weight control was the only direct driver for traditional fermented food consumption. Price, healing, health, and convenience acted as indirect drivers for traditional fermented food through the positive attitude to the traditional fermented food. In conclusion, since the formation of the positive attitude to the traditional fermented food is important for the increase of traditional fermented food consumption, the analysis of underlying food choice motives and attitude to the traditional fermented would be essential.

Purpose: We recruited 118 women in their early 20's to examine the relationship between sodium intake and salty taste thresholds and preference. We also examined the association of salty taste preference with sodium-related dietary behaviors and major dishes contributing to sodium intake. Methods: Daily sodium intake was estimated using a 127-item dish-frequency questionnaire. Salty taste thresholds and preference were measured using rating scales using water solution of NaCl and a self-administered questionnaire based on a Likert scale, respectively. Results: Salty taste preference showed positive correlation with daily sodium intake and sodium intake-increasing behaviors, and inverse association with sodium intake-decreasing behaviors, including salt and soy sauce use at the table, the frequency of eating out and home delivery of foods, broth consumption of soup, stew or noodle soup, the use of ready-to-serve or processed foods, fresh vegetable intake, and the accommodating attitude toward bland food. Intake of sodium-contributing dishes, including ramen, spicy soft-tofu stew, radish kimchi, and dishes containing kimchi, also showed positive association with salty taste preference. Unexpectedly, detection and recognition thresholds of salty taste showed no association with salty taste preference, sodium intake, and sodium-related dietary behaviors. Conclusion: These findings suggest that salty taste preference could reflect sodium intake of individuals rather than thresholds of saltiness, and may be used as a simple and effective proxy for usual sodium intake.

Purpose: This study examined the effects of a mobile app-based program to reduce the dietary sugar intake according to the stages of the behavioral change in dietary sugar reduction in female college students. Methods: The program used in this study can monitor the dietary sugar intake after recording the dietary intake and provide education message for the reduction of dietary sugar intake. In an eight-week pre-post intervention study, 68 female college students were instructed to record all the food they consumed daily and received weekly education information. At pre-post intervention, the subjects were asked to answer the questionnaire about sugar-related nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. For statistical analysis, ANOVA and a paired t-test were used for comparative analysis according Precontemplation (PC), Contemplation Preparation (C P), and A M (Action Maintenance) stage. Results: Significant differences were observed in the frequency of snacking, experience of nutrition education, and preference for sweetness according to the stages of behavior change in dietary sugar reduction. After finishing an intervention, the sugar-related nutrition knowledge score was increased significantly in the stages of Precontemplation (PC) and Contemplation Preparation (C P). The score of the sugar intake behavior increased significantly in all stages. The intake frequency of chocolate, muffins or cakes, and drinking yogurt decreased significantly in the PC stage and the intake frequency of biscuits, carbonated beverages, and fruit juice decreased significantly in the C P stage. Subjects in the PC and C P stages had an undesirable propensity in nutrition knowledge, sugar-intake behavior, and sugar-intake frequency compared to the A M stage, but this intervention improved significantly their nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. Conclusion: This program can be an effective educational tool in the stages of PC and C P, and is expected to further increase the usability and sustainability of mobile application if supplemented appropriately to a health platform program.

Purpose: This study examined the effects of nutritional education related to sugar in elementary school children on nutritional knowledge, attitude, and dietary behavior. Methods: A questionnaire survey on the knowledge, attitudes, and intake related to sugar was conducted on 572 students in grades 4-5, who were attending five elementary schools in Seoul and Gyeonggi-do. Results: Among the survey subjects, 270 (49.8%) were cognitive in education, and 302 (50.2%) were non-cognitive. The sugar-related knowledge score was 3.67 points in the cognitive education group, which was significantly higher than the 3.55 points in the non-cognitive group. The rate of checking the sugar content in the nutrition label was 31.2% in the cognitive education group, which was significantly higher than in the non-cognitive group, 15.4%. The cognitive education group had a higher intake frequency of unsweetened candy, jelly, and raw fruits, and higher sugar intake of unsweetened bread, white milk, and raw fruits than the non-cognitive group. In the case of the cognitive education group, the total knowledge score showed a positive correlation with the food behavior scores, and a negative correlation with the frequency of purchasing snacks after school, and the average sugar intake per day. In the cognitive education group only, the education of nutrition teachers was analyzed as a factor to reduce the total sugar intake. The cognitive group of sugar education tried to eat foods with a lower sugar content than the non-cognitive group, and nutrition education was an important factor affecting the sugar intake. Conclusion: To reduce the sugar intake of elementary school students, it will be necessary to practice oriented-nutrition education by nutrition teachers continuously. In addition, it is important to develop and disseminate various types of nutrition education materials related to sugar that can be utilized easily by nutrition teachers.

Purpose: To investigate the effect of eating behavior on nutritional status according to temperament type. Methods: One thousand one hundred three preschool children aged 2 to 6 years in Gyeongsan, Gyeongsangbuk-do from April to June 2018 were surveyed about their eating behavior and nutritional status using DBT (Dietary Behavior Test) and NQ (Nutrition Quotient) which are proven tests. The dietary behaviors of the children were classified into four categories: approach avoidance, sensory sensitivity, hyperactivity, and irregularity. NQ scores were divided into five categories: balance, diversity, moderation, regularity, and practice. Results: The mean of the children's age was 3.42 ± 1.4 (596 boys and 507 girls). The percentage distribution of the NQ grade was as follows: 5.5% (highest), 12.5% (high), 47.1% (medium), 22.2% (low), and 12.6% (lowest). The risk group of approach avoidance and sensory sensitivity had significantly (p < 0.001) lower scores than the normal group in balance factor (51.9 ± 12.0 vs. 57.8 ± 15.9 in approach avoidance type, 52.6 ± 17.6 vs. 57.7 ± 15.9 in sensory sensitivity type) and diversity factor (32.5 ± 24.4 vs. 50.1 ± 22.4 in approach avoidance type, and 32.5 ± 24.0 vs. 50.7 ± 22.2 in sensory sensitivity type). The scores of the hyperactivity risk group were significantly lower in moderation factor (78.2 ± 12.1 vs. 81.2 ± 11.9), and those of the irregular risk group were significantly lower in variety (35.9 ± 24.5 vs. 48.8 ± 23.2), regularity (57.6 ± 37.1 vs. 66.1 ± 17.6), and practice (57.1 ± 19.4 vs. 65.1 ± 22.5) factors than the normal group (p < 0.001). Especially, the risk group of approach avoidance and sensitivity type had significantly (p < 0.001) lower intakes of whole grain, fruit, bean and bean products, vegetables, and Kimchi. Conclusion: This present study suggested that the eating behavior based on temperament of demanding preschool children affected food choice resulting in food consumption diversity of children. Therefore, it is important to provide customized nutrition education programs based on temperament type.
