The Breakfast Club of the Seoul Metropolitan Government aims to provide breakfast and nutrition education to students who require need breakfast. This study was conducted to explore the experience of changes at the individual and environmental levels among high-school participants of the Breakfast Club. The qualitative data were collected from 20 high school students (10 boys and 10 girls) via a focus group interview at each school. Experienced improvement and suggested future tasks from the experience of the Breakfast Club were categorized at three levels (themes): personal factors, school environmental factors, and home environmental factors. The health belief, knowledege, awareness, and perception of effects of the participants showed improvement but the personal barriers need to be improved. At the school level, peer influence and school food policies were improved but some aspects of availability and accessibility for breakfast, and social norms need to be improved. The factors related to the home environment, such as family influence, and availability and accessibility for breakfast were better after the program. The Breakfast Club changed not only personal behaviors but also the family and school environments.

Purpose: Not enough attention has been paid to defecation habits in Japan. This study aimed to emphasize the importance of defecation habits on health and function in Japanese pupils. Methods: Using multiple regression analysis, 2,722 questionnaires obtained from pupils in grades 5 to 12 were analyzed to determine lifestyle habits associated with defecation frequency. Results: Significant regression formulae for defecation scores were obtained for all school types: elementary school (ES) (adjusted R²=0.08, p<0.001), junior high school (JHS) (0.09, p<0.001), and senior high school (SHS) (0.15, p<0.001). The following factors were associated with poorer defecation scores, according to school type: female gender (all 3 school types), breakfast skipping (elementary and JHSs), lower physical activity (JHSs and SHSs), and longer school-day screen time (elementary and SHSs). In addition, poorer self-reported academic performance scores in ES, less standardized body mass index (BMI) in JHS, and shorter non-school- day screen time scores in SHS, were associated with poorer defecation scores. Conclusion: Poor defecation frequency showed significant associations with various lifestyle habits, such as breakfast skipping, physical activity, and screen time, among pupils. Academic performance and standardized BMI were also associated with defecation frequency. More attention should be paid to defecation frequency to sustain health and function in pupils.

Purpose: Only a few studies have explored nationwide trends in lipid profiles among Asian adolescents. We aimed to assess trends in lipid profiles and the associated lifestyle factors among Korean children. Methods: We analyzed data for 2,094 adolescents who were aged 10-18 years and had participated in the Korea National Health and Nutrition Examination Surveys in 1998 and 2010. Results: During 1998-2010, the prevalence of obesity significantly increased in boys, but no changes were observed in girls. Over this period, there was a small but significant decrease in the mean lowdensity lipoprotein (LDL)-cholesterol level in boys (1998, 87.5 mg/dL; 2010, 83.6 mg/dL; P=0.019) and mean triglyceride levels in girls (1998, 90.8 mg/dL; 2010, 85.8 mg/dL; P=0.020). There were no significant changes in the prevalence of dyslipidemia in boys, but a modest decrease was noted in girls (1998, 25.1%; 2010, 18.3%; P=0.052). During the study period, the prevalence of breakfast skipping decreased, whereas that of regular exercise increased in both groups. Daily total energy intake did not change between these years. In multivariable logistic regression analyses, breakfast skipping was associated with increased risk of hyper-LDL-cholesterolemia in boys (odds ratio [OR], 5.77) and hypertriglyceridemia (OR, 2.27) in girls. Regular exercise was associated with decreased risk of hypo-HDL-cholesterolemia (OR, 0.40) in boys. Conclusion: Although the prevalence of obesity in boys increased, favorable or constant trends in lipid profiles were observed among Korean adolescents during 1998-2010. Decrease in breakfast skipping and increase in regular exercise may have contributed to these trends.

This study was conducted to find the number of meals skipped and the types of main meals consumed by people in Miryang and Daegu. The subjects consisted of elementary school students(ES), middle school students(MS), high school students(HS), college students(CS) and adults, divided into below the age of 40(AU) and above the age of 40(AA). Data were collected through a 7-day dietary record from 941 subjects. The definition of rice-based meal(RM) and wheat-based meal(WM) depends on the type of grain eaten in the main dish, rice or wheat flour, respectively, regardless of the menu. Out of all the meals consumed by the subjects during 7 days before the survey, 71.5% of the meals consumed were RM, 13.1 ％ of the meals consumed was WM and 12.5% of the meals was skipped. Of the meals skipped, breakfast-skipping was the highest with 27.1%. There's no difference by region and sex. But there were several differences by age. The rates of skipped meal were high for CS, AU, HS, and MS in order. Especially the breakfast-skipping for CS was highest as 47.9%. In the types of main meal, the rates of RM was highest at breakfast and lowest at lunch. The rates of RM was higher in Miryang than Daegu, and there was no difference by sex. The rates of RM was high for AA, HS, ES and AU in order. ES and HS, who had highest rates of WM, had the highest WM consumption at lunch. It is because of school food service at lunch. Since the younger population consumed more RM compared to the older population, it can be speculated that more WM will be consumed in the future. Also efforts need to be made to discourage skipping meals.

The aim of this study analyzed changes in dietary habits and lifestyles before and after COVID-19 targeting adolescents, using the food consumption behavior survey (2019 vs 2021). In the change in health-related factors, height decreased overall, and a significant difference was especially evident in males. Awareness that functional foods and eco-friendly foods contribute to health has increased. Among the results of dietary behavior, the frequency of skipping breakfast showed that the rate of not skipping breakfast and the rate of skipping breakfast more than 5 times increased at the same time(p=0.019). The rate of eating out decreased significantly after COVID-19, and it was analyzed that schools and school cafeteria, as well as Street carts or restaurants and academy, all increased significantly as places where snacks were not consumed. In order to analyze changes in food-related lifestyle, it was grouped into convenience-seeking, quality/safety-seeking, taste-seeking, and health/safety-seeking. 'Small packaged or pre-processed products' decreased. On the other hand, items such as 'Safety rather than price when choosing food' and 'Don't eat food that could go bad' improved. 'Tend to eat regularly' was higher than 2021 compared to 2019. Also 'Tend to purchase HACCP and GAP-certified products' are increased. Because of COVID-19 changes in lifestyle have affected the diet of adolescents. The results of this study suggest that it can be used as a guideline establishment and nutrition counseling material for the formation of correct eating habits for adolescents in the future pandemic era.

We examined the relationship between breakfast eating, nutrient intake, and health outcomes using dietary intake, anthropometric, and biochemical measurements in Korean adults. Data from the 2007 National Health and Nutrition Survey were obtained, and 2,514 adults aged 20 to 64 years were analyzed. The prevalence of skipping breakfast, using a 24-hour diet recall, was 54.5% in the 20-29 age group, 31.2% in the 30-49 age group, and 19.2% in the 50-64 age group. In the 20-29 age group, waist circumstance and serum cholesterol were significantly higher in breakfast skippers than in breakfast eaters. In the 30-49 age group, breakfast skippers had higher triglyceride levels than breakfast eaters. Energy intake of breakfast skippers in every age group was significantly lower than that of breakfast eaters. Furthermore, in the 20-29 and 30-49 age groups, the percent of energy from carbohydrates in breakfast skippers was significantly lower than that of breakfast eaters, whereas the percent of energy from lipids in breakfast skippers was significantly higher than that of breakfast eaters. Additionally, in the 20-29 and 30-49 age groups, breakfast eaters showed higher carbohydrate and iron intake per 1,000 kcal than breakfast skippers and lower lipid intake per 1,000 kcal than that of breakfast skippers. Breakfast skippers showed intakes of less nutrients than EAR was higher than breakfast eaters except vitamin B2 and calcium intake in males of the 20-29 age group. In conclusion, nutrition education, and policy should be implemented to teach the importance of breakfast, appropriate dietary intake, and proper food choice for each age group.

Objectives: To identify and evaluate the trend of meal-skipping rates among Korean adolescents with their contributing causes and the influence of household income level on meal skipping. Methods: Using 2008, 2010, and 2012 data from the Korea Youth Risk Behavior Web-based Survey of 222 662 students, a cross-sectional study with subgroup analysis was performed. We calculated odds ratios for skipping each meal 5 or more times in a week by household socio-economic status using a multiple logistic regression model. The secular change in the meal-skipping rates by the students' family affluence scale was analyzed by comparing the meal-skipping students within each subgroup and odds ratios for the same event over time. Results: Through 2008 to 2012, most of the meal-skipping rates generally showed a continuous increase or were almost unchanged in both sexes, except for breakfast skipping in several subgroups. Students in low-income households not living with both parents had the highest meal-skipping rates and odds ratios for frequent meal skipping. In a time-series subgroup analysis, the overall odds ratios for the same event increased during 2008 to 2012, with a slight reduction in the gap between low and higher income levels with regard to meal skipping during 2010 to 2012. Conclusions: Household socio-economic status and several other factors had a significant influence on Korean adolescent meal-skipping rates. Although the gap in eating behavior associated with household socio-economic differences is currently decreasing, further study and appropriate interventions are needed.

BACKGROUND/OBJECTIVES: Skipping breakfast is prevalent in young adult women. This study examined the psychosocial factors and eating behaviors according to the breakfast frequency among female university students. SUBJECTS/METHODS: The subjects were female university students in Seoul, South Korea. A survey was done, and the data from 291 students were analyzed. The subjects were categorized into a high breakfast group (HBG) and low breakfast group (LBG). Analysis of covariance and multiple linear regression were mainly used in data analysis. RESULTS: The subjects had breakfast 3.6 days/week on average. The HBG (47.4%) and the LBG (52.6%) differed significantly in breakfast status, including place, people eating together, breakfast menu, and breakfast preparers (P < 0.001). The HBG agreed more strongly with the advantages of breakfast than the LBG (P < 0.001). The disadvantages/barriers of breakfast were stronger in the LBG (P < 0.001). The HBG felt more confidence in having breakfast (P < 0.001) and confidence in general eating behaviors (P < 0.05). The two groups also differed in the subjective norms from parents/professionals (P < 0.001) and siblings/friends (P < 0.01). The HBG showed desirable eating behaviors more frequently (P < 0.001) and undesirable eating behaviors less frequently (P < 0.001). Multiple regression showed that the following were significantly related to the breakfast frequency, explaining 57.3% of the variance: self-efficacy regarding having breakfast (P < 0.001), perceived barriers of breakfast (no appetite/habit/indigestion, P < 0.001), desirable and undesirable eating behaviors (P < 0.01), subjective norms from parents/professionals (P < 0.05), and perceived barriers due to lack of time/preparation difficulties (P < 0.05). CONCLUSIONS: Psychosocial factors and eating behaviors were significantly related to the breakfast frequency. Nutrition education might include strategies to increase self-efficacy for breakfast, modify the beliefs, particularly the disadvantages/barriers of breakfast, adopt desirable eating behaviors, and elicit support from significant others.

This study was conducted to determine the correlation between breakfast consumption and health-related quality of life in elderly adults. It analyzed the data from the National Health and Nutrition Examination Survey from 2010 to 2012, using a sample of 4,035 people aged 65 or above. Analysis followed the SAS SURVEY procedure, considering the complex sample design. A t-test, a chi-square test, and logistic regression analysis were performed using SAS version 9.3. The rate of skipping breakfast by elderly adults was 4.7%, and it was higher in women and elderly adults living alone. It also significantly differed by drinking status and BMI. Elderly adults consuming breakfast had slightly higher scores on the health-related quality of life measure than those who did not (0.85 vs 0.81). Results revealed that health-related quality of life increased with meal frequency, and that elderly adults who ate breakfast tended to score better on the pain/discomfort and anxiety/depression domains of the health-related quality of life measure. It was found that breakfast consumption associated with health-related quality of life in elderly adults. Accordingly, it is necessary to increase awareness among elderly adults regarding the importance of breakfast, and to improve their health-related quality of life by developing and implementing interventions to improve dietary habits.

The purposes of this study were to investigate the eating of breakfast by female middle school students in Seoul, the perception of the school breakfast program (SBP), and determine the factors affecting the intention to participate in SBP. Out of 340 questionnaires distributed to the female middle school students, 334 were returned (98.2% response rate) and 323 were analyzed. The subjects were categorized into two groups by the intention to participate in SBP. Subjects were classified as participating and non participating groups. As a result of analyzing the breakfast intake frequency, 'hardly eat' showed the highest with 18.5% in the participating group and 10.3% in non participating group, while 'eat every day' showed 38.2% in the participating group, and the highest with 65.5% in non participating group (p<0.001). For the reason for skipping breakfast, 'no time' showed the highest with 30.0% in the participating group, 'over sleep' and 'no appetite' showed the highest with 24.8% in non participating group. For the reason for not participating in SBP, 'breakfast should be eaten at home' showed the highest with 47.2% in non participating group and 'may get up early in the morning' showed the highest with 46.2% in participating group (p<0.01). To determine the factors affecting the intention to participate in SBP, logistic regression analyses were conducted for female middle school students. According to the logistic regression analysis, father's education level was independently associated with the intention to participate in SBP in female middle school students [Odds Ratios (OR) 2.38, 95% Confidence Interval (CI) 1.03~5.52]. Frequency of eating breakfast on weekdays (OR 1.36, 95% CI 1.01~1.81), Level of need for school breakfast (OR 0.52, 95% CI 0.35~0.76) and whether to approve school breakfast (OR 0.27, 95% CI 0.18~0.41) were independently associated with the intention to participate in SBP in female middle school students. In conclusion, proper educational efforts for importance of school breakfast could be useful plan to develop school breakfast program.
