This study was conducted to develop a cookbook for children as a nutritional education material considering the dietary behaviors of elementary school students. Dietary behaviors were surveyed in 5th and 6th grade students(male 45, female 45) in Gangwon-do. 48.9% of the children ate breakfast every day, and 67.8% ate Korean food such as cooked rice, soup, and side dishes for breakfast. The reason for skipping the breakfast was 'have no time'. 42.2% of the children answered 'cook the foods that they want to eat' about the question how to eat when they are alone at home. 52.2% of the children ate snacks 1~2 times a day, and such snacks included fruits(46.6%), ice cream(22.2%), bread or cookies(21.1%), and instant foods(11.1%). Children preferred meats to vegetables and preferred Bokeum(27.8%), Twigim(25.6%), Guk Jjigae(21.1%) to other cooking methods. 96.7% of the children have cooked at least 1 time. 64.4% of the children have cooked because they 'just want to cook.' The kinds of the foods that they have cooked were Ramen(68.8%), fried eggs(53.3%), Bokeumbap(37.8%), and sandwiches(18.9%). Considering these results, cookbooks were categorized by 'cook by myself', 'cook snacks speedily', and 'show off my cooking skills' with 5~6 dishes in each. They have pictures of a cooking process about all dishes and provide information on the contents of protein, fat, calcium, sodium as well as energy, the method to plan balanced diet by using the food pyramid and the portion size for children. This cookbook gives basic knowledge about cooking such as measuring, sanitation, and the separation of food garbage. I expect that the cookbook can be used as a nutritional education material to improve the dietary behaviors of children.

Purpose: The use of food delivery services is increasing continuously in Korea, which may lead to nutritional problems and obesity. Despite this, the research on the association between delivered food consumption and obesity has been insufficient. This study examined the relationship between delivered food consumption and dietary behaviors and obesity among young adults in Jeju. Methods: An online survey was conducted from March 15 to April 5, 2023; 312 participants aged 19-39 years were included in the final analysis. The frequency, types, and time of delivered food consumption were measured using a questionnaire. The dietary behaviors included the following: eating out, breakfast consumption, recognition of nutrition labels, and eating salty foods, vegetables, and fruit. Obesity was defined using the body mass index based on self-reported body weight and height. Results: Approximately 59.3% of the participants ordered delivery foods more than one time/week. The frequency of delivered food consumption was higher in people who consumed breakfast < 5 times/week than those who consumed ≥ 5 times/week (p = 0.0088). People who usually eat salty foods tended to consume delivered food more frequently than those who did not (p = 0.0377). On the other hand, people who consumed fruits ≥ 1 time/day had a higher frequency of delivered food consumption than those who consumed fruits < 1 time/day (p = 0.0110). After adjusting for the confounding variables, the group who consumed delivered foods more than three times/week had an increased odds ratio (OR) of obesity compared to those who consumed less one time/week (OR, 2.38; 95% confidence intervals, 1.12-5.06). Conclusion: Young adults in Jeju who frequently consume delivered foods tended to have poor dietary habits including skipping breakfast and eating salty, and they had an increased odds of obesity. The overall dietary patterns can be improved by providing nutrition education and developing policies to promote or support healthy food choices when ordering delivered foods or eating out.

This study was to analyzed the quality of the meal and the level of nutritional intake in female college students according to the place of residence in female college students. This survey was conducted through questionnaire was given to 359 female students. The subjects were divided into two groups : one group was comprised of those the students who resided in a self-boarding house(SB group, n=245), and the other group comprised of was the student those who resided in the same house with their parents(HWP group, n=114). The mean age of the subjects were 21.6 years old(SB) and 20.6 years old(HWP)(p<0.05). The average height, weight and BMI were 161.8 cm, 57.9 kg, $20.3kg/m^2$ in the SB group and 161.9 cm, 53.4 kg, $20.3kg/m^2$ in HWP group, respectively. The SB group had significantly higher frequency of skipping breakfast and alcohol drinking consumption than the HWP group. There was no significant differences in the mean daily energy intakes between the SB and the HWP groups. However, the plant protein(p<0.01), carbohydrate (p<0.05), vitamin $B_1$(p<0.01), vitamin $B_2$(p<0.05), vitamin C(p<0.01), plant calcium(p<0.01) and potassium(p<0.05) intakes were significantly lower in the SB group were lower than the intakes in the HWP group significantly. And in addition, the cereals(p<0.05) and fruits(p<0.001) intakes in the SB group were significantly lower than the intakes in the HWP group. There was no significant differences in the KDDS and DVS between the two groups, but there was a decreasing trending downward. For that reason, the SB students seemed appeared to have more dietary problems than the HWP students. These results suggest that nutritional education for SB students are is needed in order to supply the lack of management capability on the proper help improve the diet of students living in independently life.

Purpose: The purpose of this study was to identify the factors that influence the consumption of convenience foods among Korean adolescents. Methods: This study had a descriptive cross-sectional study. Data were obtained from the 15th (2019) Korea Youth Risk Behavior Web-based Survey, which involved a nationwide representative sample of 57,303 middle- and high-school students. Convenience-food consumption was defined by frequency of adolescents consuming convenience foods obtained from convenience stores, supermarkets, and cafeterias over the previous 7 days. The analyzed variables were related to sociodemographic, mental health, and health behavior. The Rao-Scott χ² test was applied to examine the difference in the rate of consuming convenience foods obtained from convenience stores according to each factor. Hierarchical logistic regression was conducted to examine the factors that influence convenience-food consumption among Korean adolescents. Results: It was found that 29.1% of Korean adolescents consumed convenience foods obtained from convenience store more than three times per week. The significant influencing factors were female sex; low subjective academic achievement, and subjective household economic status; high perceived stress; low subjective sleep sufficiency; experience of depression; suicidal ideation; lower physical activity; skipping breakfast; lower consumptions of fruit, milk, and vegetables; higher consumptions of soda drinks, sweet drinks, caffeine, and fast food; lower water intake; current smoking and drinking; drug use; and experience of violence. Conclusion: These findings provide a better understanding of the sociodemographic, mental-health, and health-behavior factors that influence the consumption of convenience foods among Korean adolescents. We suggest that differentiated policies, strategies, and nutrition education need to be developed and implemented, in order to address the above-mentioned factors and thereby reduce such behaviors among Korean adolescents.

Objectives: This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females. Methods: A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group. Results: The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group. Conclusions: The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

Objectives: The purpose of this study was to examine factors associated with the self-rated health status of the elderly and whether these factors were different from younger adults. Methods: An interview survey was conducted on non-institutionalized adults in Wonju City, Korea. Determinants of self-rated health status were identified and compared between individuals aged 19 to 64 years and those aged 65 years and over, using an ordered logistic regression conducted separately on these two groups. Participants were 1,685 younger adults and 188 elderly people. Self-rated health status was measured along a continuous scale from 0 to 100 (0 for the worst and 100 for the best they could imagine) and then binned into 11 categories. Results: Self-rated health status of the elderly in Wonju was associated with household income, education, bereavement, adequate sleep, daily and social life being affected by poor health status, mobility, and anxiety and depression. Household income, adequate sleep, and participation in social activities were significant only in the elderly, while some factors associated with the self-rated health status of younger adults, such as rural dwelling, regular exercise, living alone, and skipping breakfast were not significant in the elderly. Conclusion: In order to improve the health of the elderly in Wonju City, it would be necessary to develop programs addressing those specific needs of the elderly and to integrate them effectively in the Healthy City projects.

This study is a convergence study designed to suggest healthy eating out choices by grasping the relationship between determinants of delivery food and eating habits. The subjects of this study were 505 adults in their 20s and 30s who had an experience in delivery food. The data were analyzed by factor analysis, cluster analysis, χ² analysis, ANOVA analysis and Duncan's post analysis using the SPSS 25.0 program, and the research results are as follows. The convenience-seeking type had a high rate of late night eating, drinking, and breakfast skipping, while the saving-seeking type had a high score of food practice score. The utility-seeking type had a significantly lower quality of life (WHOQOL-BREF) score. Therefore, the educational direction suggested according to the tendency identified in the determinants of delivery food can be used as basic data for the selection of healthy delivery food. In the future, research and nutrition education through grasping the route of determinants of delivery food are also expected to be necessary.

The purpose of this study was to compare dietary attitudes, dietary behaviors and diet qualities of Food and Nutrition major and non-major female student at a university located in Inchon. The subjects included 74 female Food and Nutrition and majors and 45 non-Food and Nutrition major female university students. This cross-sectional survey was conducted using a self-administered questionnaire, and the data were analyzed by a SPSS 10.0 program. The nutrient intake data collected from Three-day recalls were analysed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Mean Adequacy Ratio (MAR), the Nutrient Adequacy patio (NAR) and the Index of Nutritional Quality (INQ). There was no significant difference in dietary behaviors between Food and Nutrition majors and non-majors. However, most of the female university students had poor eating habits, such as overeating, unbalanced meals, and skipping of meals. In particular, more than 50% of the female university students skipped breakfast. As for weighing themselves once a week, changing dietary lifestyles, calculating food calories and having interest in information on nutrition on health, the ratio of Food and Nutrition majors was significantly higher as compared to that of the non-majors. There was a significant difference in food consumption frequency except for mick and milk products, and iron-rich foods between the Food and Nutrition majors and non-majors. However, there was a significant difference in the frequency scores of iron-rich floods between the Food and Nutrition majors and non-majors. The MAR of Food and Nutrition majors and non-majors were 0.80$\pm$0.13, 0.79$\pm$0.13, respectively. However, in the Food and Nutrition majors and non-majors, the NARs of calcium were 0.61$\pm$0.21 and 0.59 $\pm$ 0.20, and that of iron were 0.61$\pm$0.21 and 0.59$\pm$0.16, respectively, which was extremely low when compared to that of the other nutrients. This result was similar to that of the INQ. Therefore, nutritional education is necessary if female university students are to practice optimal nutrition, including well-balanced diets and eating foods of high nutritional quality.

Balanced intake of appropriate nutrients is the key to sustaining and promoting health as well as preventing and treating diseases. It is not always easy, however, to take balanced nutrition and various related factors must be taken into consideration. This report provides a summary of studies that have examined the nutrient intakes of Japanese middle-aged men and the relationship of this intake to drinking, job-related separation from families, and health practices. The alcohol consumption of Japanese middle-aged men has more than tripled in the last forty years. When nutrient intake was examined in relation to alcohol consumption, it was discovered that the maximum acceptable alcohol consumption was approximately 23 grams (about two drinks) of pure alcohol, provided the level of nutrient intake for drinkers was equal to that of non-drinkers. The alcohol energy ratio was approximately 5％. It was also discovered that middle-aged men's eating habits deteriorate when they relocate to new posts without their families and live by themselves. Compared to those living with their families, a higher proportion of those living alone have unfavorable eating habits including skipping breakfast or lunch, having a late lunch, and eating and drinking after dinner until bedtime. When Breslow's seven health practices, nutrient intake, and consumption weight by food group were examined, it was discovered that the group that had many beneficial eating and living habits consumed plenty of legume, pulses, fruit, green yellow vegetables and milk products. Their intake of vitamins and minerals was high and the results of a physical examination proved to be excellent. According to nutrition surveys conducted in Japan, China, the United Kingdom and the United States using a 24-hour recall method with common protocols and strict controls to ensure high levels of accuracy and cross-study validity, the Japanese had the highest cholesterol intake and the lowest dietary fiber intake among the four countries. Also, the alcohol energy ratio of the Japanese exceeded 8％, the highest among the four countries, while their intake of magnesium and iron was the lowest These results indicate that it is necessary to enhance nutritional education for middle-aged men and to reinforce the social environments in which they live and work in order to promote proper diet and nutrition in Japan.
