We aimed to evaluate the effect of nutrition education program on nutrition knowledge, dietary behavior, dietary intakes and anthropometric parameters in primary school children. Eighty five 4th grade children (boys = 43, girls = 42) were enrolled in the intervention program for 5 months. The subjects were asked to fill out a questionnaire about nutrition knowledge and dietary behavior two times, at the baseline and after completion of the program. Dietary intake information was collected from participants using a 3-day food record and their anthropometric parameters were measured. Upon completion of the intervention program, both nutrition knowledge and dietary behavior scores were significantly improved in all subjects. Energy intake was increased from 1,571.9 kcal to 1,734.1 kcal with significant improvements in nutrient density for protein, Ca, P, K, vitamin A and niacin. While subjects' height, weight, lean body mass and soft lean mass were significantly increased during the program, significant decreases were observed in the rohrer index, percent body fat, waist-hip ratio and body fat mass. The changes in nutrition knowledge scores were positively correlated with the changes in dietary behavior scores, micronutrient intakes and anthropometric parameters. These results indicate that enhancement of nutrition knowledge through well-planned long-term nutrition education program is effective not only for the improvement of dietary behaviors and dietary intakes but also for the positive changes in anthropometric parameters among primary school children.

Objectives: This study aimed to investigate the association between how often Korean adolescents watch Mukbang and Cookbang videos and their dietary habits. Methods: Data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 was analyzed for this study. The study included 51,850 middle and high school students and assessed various aspects, including demographics, frequency of watching Mukbang and Cookbang videos per week, dietary habits, health behaviors, and mental health factors. Results: Nearly a third (29.3%) of Korean adolescents watched Mukbang and Cookbang videos one to four times a week, while 13.5% watched them more than five times weekly. Females, those with lower academic achievement, and those from lower socioeconomic backgrounds were significantly more likely to be frequent viewers (P < 0.001). Increased viewing frequency was associated with poorer dietary habits. Adolescents who watched more frequently were less likely to eat breakfast and consume fruits and milk, while their consumption of fast food, high-caffeine drinks, sugary drinks, and late-night snacks increased (P < 0.001). Higher viewing frequency correlated with increased feelings of stress, depression, and loneliness (P < 0.001). Logistic regression analysis confirmed these associations. More frequent viewers were significantly less likely to eat breakfast (odds ratio (OR), 0.63; 95% confidence interval (CI), 0.58-0.68), and more likely to consume fast food (OR, 1.85; 95% CI, 1.69-2.02), high-caffeine drinks (OR, 1.43; 95% CI, 1.30-1.56), sugary drinks (OR, 1.54; 95% CI, 1.41-1.67), and late-night snacks (OR, 1.37; 95% CI, 1.25-1.51). Conclusions: Our findings suggest that frequent exposure to Mukbang and Cookbang content is linked to unhealthy dietary habits in adolescents. Educational programs may be necessary to mitigate the potential for these videos to negatively influence dietary choices.

Objectives: This study was performed to identify the socioeconomic factors, health behavior factors and dietary patterns that have an influence on the fasting blood glucose in adults. Methods: This study used data collected from the 2007, 2008, 2009 Korea National Health and Nutrition Examination Survey. The final sample included 4163 subjects who were 30-59 years old and who had completed the necessary health examinations, the health behaviors survey and nutrition survey. Results: Eleven dietary patterns emerged from the factor analysis with different factor loading. After controlling for potential confounders, multiple regression analysis of the dietary patterns showed that 'fruits', 'alcohols', and 'starchy foods' affected the fasting blood. Lower consumption of 'fruits' and higher consumption of 'alcohols' and 'starch foods' were significantly associated only with an increased risk of high blood glucose. Conclusions: In the light of the results of this study, it appears pretty likely that the risk of developing high blood glucose can be reduced by changing a person's dietary patterns.

BACKGROUND/OBJECTIVES: Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS: We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS: Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS: These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

This study was conducted to investigate the dietary behaviors and health-related lifestyles, according to exercise habits, of female university students in the Jeonju area. Self-administered questionnaires were collected from 285 students, and the statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. The weight, height, and BMI averages of the regular exercise and non-exercise groups were 53.05 kg, 162.46 cm, and 20.23, and 50.81 kg, 161.46 cm, and 19.48, respectively. The breakfast skipping ratio was higher in the non-exercise group than the exercise group. More than 72% of the exercise and 71% of the non-exercise group responded to regularly having lunch at the university canteens or restaurants around campus. Approximately 70% of the exercise and 71% of the non-exercise group responded to having dinner irregularly, which was mainly caused by reasons such as 'irregularity of life style' and 'appointments with friends'. The snack intake ratios of the exercise and non-exercise groups were high, but the exercise group ate more fruit, yogurt, and milk than the non-exercise group. The favorite sports of the exercise group were 'walk(jogging)', 'yoga', 'bicycle,' 'swim,' etc. In particular, 5.3% of the exercise group had ridden a bicycle to the university. More than 97% of the students were non-smokers. About 14% of the exercise and 15% of the non-exercise group rank alcohol once or twice a week. The exercise group did not show exceptional health-oriented dietary behaviors in comparison to the non-exorcise group. Therefore, an exercise-oriented nutrition education program would be beneficial to the students, in order to improve their dietary behaviors and health-related lifestyles.

Objectives: This study was conducted to investigate the relationship between watching mukbang (eating broadcasts) and dietary and health behavior in adults who watch mukbang. Methods: The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing mukbang, delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to mukbang viewing time. Results: The body weight of viewers was significantly higher when mukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high mukbang viewing time per week, the frequency of food delivery and night eating was high. When mukbang viewing time was high, the viewer's interest in health was low and the frequency of exercising too was low. Conclusions: Viewers with high mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.
