The purpose of the study is to investigate the relationships between the BMI and food preference. eating behaviors. and nutrition knowledge score among the middle school male and female students. A total of 394 students from 4 different middle school in Seoul were participated in this study. The students were categorized into 3 groups by BMI : under-weight(〈20). ideal(20$\leq$BMI〈25). and overweight($\geq$25) groups. The data on food preference. eating behavior. and nutrition knowledge were collected by a questionnaire. All data were analyzed by means as frequency. percentage. mean and standard deviation. F-test. $\chi$$^2$-test. and correlation analysis. The results obtained are summarized as follows : 1. BMI average of the male students was 21.4 About 45% of the students were in ideal weight group. 40% were in under-weight group. and 15% were in overweight group according to BMI. 2. About 62% of the participants wanted to lose weight : 43% of the male students. and 82% of the female students. And 33% of the students wished to lose more than 7kg of body weight. 3. Preference score for animal protein foods was the highest in overweight group. On the other hand. preference score of vegetables was the highest in under-weight group. 4. All 3 BMI groups eat more foods on dinner compared to lunch or breakfast. Eating amount score of between-meal was highest(eat more) in under-weight group. and the lowest(eat less) in overweight group. But the percentage of students who eat snack at night was the highest in overweight group. 5. Among the eating behavior variables. eating frequency of snack at night and eating speed were significantly different among 3 groups. Overweight group eat snack at night less frequently and eating speed is faster than the other groups(p〈.05). 6. Nutrition knowledge score was the highest in overweight group. but the difference was insignificant. It is shown that about 40% of the participants belong to under-weight group. but 62% wished to lose weights. Parents and teachers should watch out the juvenile students'health. especially whether they try to lose weight or maintain unrealistically low weight.

Objectives: This study was carried out to measure knowledge, attitude, and practice and related factors of low-salt diet among university students. Methods: Data from a convenience sample of 251 nursing and engineering students of two universities in south-western part of Korea were collected during March 16~20, 2015 using a self-reporting questionaire and urine test. The instruments developed by Lee and Song(1999) were used to measure knowledge and practice, and Ahn(2013) for attitude toward low-salt diet. A spot urine salt stick($SaltSinal^{(R)}$) was also used to evaluate practice of low-salt diet. Data were analyzed using SPSS 21.0, and t-tests, ANOVA, Pearson correlation, and Scheffe test were used. The study was IRB approved. Results: Knowledge, attitude, and practice of low-salt diet was low and spot urine salt level was high among university students. Knowledge and attitude were higher and spot urine salt level was lower among nursing students. Knowledge and attitude were related to gender and drinking. Living arrangement, monthly allowance, smoking, frequency of eating-out, frequency of breakfast were shown not to be related to knowledge and attitude. None of the variable investigated were significantly related to practice of low-salt diet. However, spot urine salt was related with gender, living arrangement, and smoking. Conclusions: A rigorous health education is necessary in order to lower dietary salt among university students. Considering frequent eating-out among university students, it is also very important to lower salt amount in foods sold on- and off-campus.

Purpose： The purpose of this study was to estimate obesity rate among mentally disabled children in six public schools in Korea. Furthermore, this study identified several factors that correlated with these children's obesity. The results of this study can help identify mentally disabled children who are at an increased risk for obesity and can be used to promote good health in this population. Methods： 1,102 subjectsfrom six public special schools were classified 4 groups who assessed for BMI for age-gender specific reference chart(1998) based on our previous data. Moreover, 207 parents were surveyed to identify predisposing factors for children's obesity, including characteristics of the children and parents, socioeconomic factors, children's eating habits, and children's exercise habits. Results： The prevalence of obesity among the 1,102 mentally disabled children was 17.3%. There was a statistically significant correlation between obesity and factors, such as age, maternal education, parents' perceptions about their child's obesity, frequency of breakfast, and exercise habits. Each of these factors was determined to have a statistically significant influence on obesity when all other factors were controlled in a multivariate analysis with multiple logistic regression analysis. Conclusions： Parental perceptions had an especially strong impact on the weight of their mentally disabled child. This is presumably due to the great influence that parents have on the lifestyles of their children, including dietary habits and frequency of exercise. Furthermore, the rate of obesity was directly proportional to the age of the child. The results of this study strongly indicate the need for preemptive health education programs that stress weight management for mentally disabled elementary school students.

The objective of this study is to analyze the characteristics of persons with a high sugar-intake ratio (%E) and factors affecting sugar-intake ratio with the Korea National Health and Nutrition Examination Survey ($6^{th}$ KNHANES). The sugar-intake ratio is the calories of sugar from processed food divided by the daily total intake of calories. In this research we used two statistical methods, the cluster analysis and one-way analysis of variance (ANOVA). Cluster analysis was used to classify groups of sugar-intake ratios. For analysis of factors affecting the sugar-intake ratio, we applied the ANOVA. Korean have about a 3.89% sugar-intake ratio from processed food per day. The demographic characteristics of people with higher sugar-intake ratios were found to be more women than men, younger men with less education, more people in the household, smaller height, weight waistline and body mass index (BMI). Also office worker, lower drinking frequency, not getting a hypertension, diabetes, hyperlipidemia, lower breakfast and dinnner frequency, not experiencing nutritional education, and not using nutritional labeling. For reducing intake sugar in what are called health-hazardable nutrients in the food sanitation act, it is necessary to educate the people with high sugar ratio who were identified in this study.

In this study, we aimed to explore whether eating alone is associated with mental health conditions in Korean adolescents. The data of 2,012 Korean adolescents aged 12-18 years were obtained from the Korea National Health and Nutrition Examination Survey 2015-2019. Participants were classified into three groups based on the frequency of eating alone: none (all meals with others); 1 meal/day alone; and ≥2 meals/day alone. Mental health conditions were assessed based on stress recognition, depressive symptoms, and suicidal ideation. Multivariable logistic regressions were employed to calculate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) of poor mental health conditions according to the frequency of eating alone. Adolescents who ate ≥2 meals/day alone had higher odds of stress recognition (AOR: 2.65, 95% CI: 1.94-3.63), depressive symptoms (AOR: 2.55, 95% CI: 1.47-4.42), and suicidal ideation (AOR: 2.53, 95% CI: 1.05-6.08) than those who ate all their meals with others. In addition, having breakfast or dinner alone increased the odds of stress recognition. Considering the continuous increase in the social phenomenon of eating alone, nutritional educations are needed to develop adolescents' ability to choose more nutritionally balanced and healthy meals when eating alone.

Objectives: This study was performed to examine the consumption patterns of convenience food at convenience stores, dietary habits, and perception as well as knowledge of food additives among university students. Methods: Subjects were 352 university students in Cheongju, Korea, and data was collected by a self-administered questionnaire. They were divided into three groups according to the frequency of consumption of convenience food at convenience stores: 79 rare (${\leq}1$ time/month), 89 moderate (2-4 times/month) and 184 frequent (${\geq}2$ times/week). Results: More subjects from the frequent consumption group lived apart from parents (p<0.001) and possessed more pocket money (p<0.01). Frequent consumption group consumed noodles, Kimbab, and sandwich & burger significantly more often (p<0.001, respectively) than others. In addition, frequent consumption of convenience foods at convenience stores was associated with frequent breakfast skipping (p<0.05), irregular meal time (p<0.01), snacking (p<0.05), and eating late night meal (p<0.001). More from the rare consumption group had heard about food additives previously compared to the frequent consumption group (79.7% vs. 63.6%, p<0.01). Frequent consumption group showed significantly higher score than did the rare consumption group for the following questions: monosodium glutamate is harmful to your health (p<0.05), food additives are necessary for food manufacturing (p<0.005), food additives need to be labeled on products (p<0.05), there is no food additive at all if labeled as no preservatives, no coloring, and no added sugar (p<0.05). There was a significant difference in degrees of choosing products with less food additives depending on the consumption pattern. Conclusions: Our results provided a better understanding of the factors associated with frequent consumption of convenience foods at convenience stores among university students and will be useful to develop a nutrition education program for those who are more prone to consume convenience foods.

Objectives: The purpose of this study was to explore the factors that influence aerobic physical activity among Korean adults, including sociodemographic characteristics, health behavior, health status, social relationships, community satisfaction, and to find ways to increase aerobic physical activity among adults. Methods: In 2019, 191,152 adults in the Community Health Survey were analyzed, and complex sample frequency analysis, Rao-Scott test and complex sample logistic regression analysis were conducted by dividing them into the presence or absence of aerobic physical activity practice. Results: The rate of aerobic physical activity among adults was 36.0%, and males were higher than females. Among individual factors, gender, age, income level, smoking, drinking, weight control attempt, frequency of breakfast, obesity, quality of life, and subjective health status were factors that had a significant effect. Among social relationship factors, leisure activities and contact with neighbors at least once a week were significant factors, and only overall safety level satisfaction was a factor that had a significant effect on physical activity practice in community satisfaction factors. Conclusion: Programs focused on personal factors, social relationships, and networks should be strategically developed to improve the participation rate of adult aerobic physical activities, indicating the importance of these factors over community infrastructure. To development of community-centered professional integrated health education will be necessary in the future.

This study was a secondary data analysis conducted to identify the factors affecting the health-related quality of life according to the stress perception level of middle-aged. Data from the 2014, 2016, and 2018 Korean National Health and Nutrition Examination Survey were used, and 7,995 people aged 40-64 who answered the level of stress perception were targeted. Data analysis was performed using IBM SPSS ver.25.0, and the significance level was set to .05. As a result of the study, in the feeling less stressed group, household income level, education level, frequency of dinning out, drinking amount at a time, smoking, subjective health, and depression were found to be significant influencing factors, and the explanatory power was 21.4% (p < .001). In the feeling a lot stressed group, household income level, education level, living with a spouse, weekly breakfast frequency, aerobic physical activity, smoking, subjective health, and depression were significant influencing factors, and the explanatory power was 38.7% (p < .001). Therefore, it is suggested to consider each influencing factor in the middle-aged stress reduction intervention.

Purpose: This study was performed to investigate the dietary behaviors and stress-related factors among male and female college students. Methods: A total of 405 college students (male-195, female-210) were recruited, of whom a questionnaire-based survey was conducted. The study investigated the general characteristics, health-related factors, dietary behaviors, and stress-related factors of the respondents. Results: The body mass index was significantly higher in males. The rates of underweight and overweight were significantly different between male and female respondents. The scores for workout frequency, health concerns and health condition were significantly higher in males, while the score for watching TV & playing computer games was significantly higher in females. The scores for meal regularity, frequency of breakfast consumption, and smoking were significantly higher in males. Eating problems showed a significant difference between males and females. The biggest source of stress was social factors, followed by college study and individual factors and the most experienced stress-induced symptom was anxiety, followed by headache and stomachache. The most popular way to overcome stress was taking a rest, followed by drinking & smoking and outdoor activity. The most preferred food under stressful conditions were alcohol or beverages, followed by hot & spicy food and sweet food, which showed a significant difference between males and females. Conclusion: These results indicate that stress affects dietary behaviors, drinking, smoking, and health status. Stress not only changes dietary behaviors, but is also related to health status. Therefore, it is necessary to develop appropriate programs for emotional stability and stress relief targeting college students which provide continuous nutrition education focused on desirable dietary behaviors and nutritional aspects.

The purpose of this study was to find out the influence of Entrance Examinees' Eating Behavior on their health condition. The examinees for Chungbuk National university in 1992 were asked to fill out the questionnaire(The total number was 1054 ; 537 males, 517 females). The statistics used for data analysis were frequency, percentage, Crosstabs, Chi-square, t-test, one-way Anova, and Multiple Regression using SPSS/PC+ Program. The results are as follows. 1. Health condition due to an eating attitude: 1) As to health condition due to the food intake freguency, those who intaked fish or meat 3-5 days a week had the best heal th condition, but those who hardly intaked fish and meat or intaked them almost everyday had rather poor health condition. Those who intaked fried foods 1-2 days a week had the best health condition. The higher the freguency intaking such food or instant food was, the worse health condition was. 2) In view of health condition according to an eating attitude, it led to very good health condition to have breakfast & supper, to eat regularly, to select the nutritious foods, and to have a balanced diet. Overeating before sleeping and no meal or overeating before exam made their health very bad. Alcohol drinking & cigarrette smoking as favorite foods appeared significantly high in the boys. The more frequently they drinked alcohol and smoked cigarrette the worse their health condition was. Those who enjoyed milk, soya milk, and korean tea as favorite beverages had the better health condition than those who enjoyed coffee and soft drinks. 2. Influence of Eating Behavior on Health Condition. 1) The food intake freguency and the eating attitude influenced each other. The higher the score of food intake frequency was, the better the eating attitude appeared. 2) As a result of this study for eating behavior influencing on their health condition, the eating attitude influenced health condition, and the higher the eating attitude score was, the better heal th condition could be.
