This study was designed to investigate the content of health behavior and to examine factors determining health behavior of nursing students(n=159) in relation to sociodemographic and cognitive variables. Cognitive variables were categorized into saliency of health, susceptibility to illness, and health locus of control. Data analysis prodecure included factor analysis and stepwise multivariate regressions using health behavior as dependent variables. Analysis showed; 1. As a whole, nursing students showed a tendency of lack in positive health behavior, especially in diet-related health behavior. 2. Multiple regression analysis revealed that the factors such as grade, saliency of health, and birth place were to be independently and significantly associated with health behavior: Upper grade students, high level of saliency, urban-born students tend to take health behavior positively. 3. The most influential factor among them was grade, but cognitive inspite of stereotype, poorly impact on health behavior with the exception health. We can guess the effect of education indirectively from these findindgs, but longitudinal studies need to consider the direct effect of education. The results also indicate that the respondents should be encouraged to take health behavior positively. The studies including more other cognitive variables would be conducted for the nursing students in relation to health behavior.

This study was carried out to provide information on the related factors for child obesity through investigation of children aged 6-12. Data was obtained on family history, dietary habits and physical examinations. Children were classified into normal(98 persons) and obese (108 persons) groups using combinations of the height f3r age, weight fir age, and weight fir height standards used by the World Health Organization. Children's height, weight and BMI showed significant differences between groups except children aged 8 for height. Birth weight, breast feeding and unbalanced diet were not associated with obesity. Overeating was a risk factor in the obese group(Odd ratio : 3.417, 95% CI 1.879-6.212). Taking nutrition pills was correlated to obesity. Odd ratio for taking nutrition pills was 0.109(95% CI : 0.024-0.492) between normal and obese group. Number of brothers didn't have any correlation to obesity. Obesity was not correlated to mother's education level or employmental status. As the result of this study, children's obesity was related to overeating and taking nutrition pills. Therefore, these results suggest that systematic dietary education and continuous parental supervision are necessary to avoid child obesity. (Korean J Nutrition 31(7) : 1158-1164, 1998)

This study was performed to investigate the relationships between obese index and major risk factors of cardiovascular disease in CVD patients. Anthropometry, food intake patterns, blood pressure, serum lipids and hematological values were analyzed in 550 patients from June, 1991 to August, 1992. The results are as follows: Total food intakes, especially total vegetable food and alcohol intakes were significantly related with obese index, so that the heavier patients tended to consume more carbohydrate and less fat. The blood pressure were observed to have positive correlation with obese index in man but not in women. However, both in men and women, blood levels of TG, TC, and VLDL tended to be related to obese index positively, while HDL and HDL-C were shown to be oppositive. So, it seems that as the degree of obesity is higher the blood pressure and blood lipids patterns worse. Therefore, these results suggest that obesity is one of the major risk factors of CVD, and for prevention & treatment of the disease, controlling body weight by nutritionally adequate diet along with alcohol restriction is necessary.

This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (${\geq}\;85$ percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

This descriptive study was designed to identify the factors associated with weight control behaviors among 273 high school girls with normal body weight. The objectives of the study were ⅰ) to evaluate subjective obesity and satisfaction with the body shape, ⅱ) to describe the weight control behaviors and the motivation, ⅲ) to reveal the relationships between the weight control behaviors and BMI (Body Mass Index), iv) to investigate the relationships between the weight control behaviors and subjective obesity and satisfaction with the body shape, and v) to investigate the relationships between the weight control behaviors and family support. The results showed that 62.6% of the adolescent girls with normal weight perceived that they were fatty and 9.9% thought they were obese. Seventy-five percent of them were not satisfied with their body shape. Eighty percent of the participants reported the main motivation of weight control was to have an attractive appearance. In this study, self-reported weight control methods included dieting (64.8%, skipping or reducing meals), exercise (36.6%), and special dieting (20.1%) such as eating an increased amount of juice or vegetables. It was shown that the subjects who were not satisfied with their body shape and perceived themselves as fatty or obese were active in exercise, diet, and other special diets. Subjects who were on diets and special diets had a higher level of BMI than who were not on diet and special diet. Subjects who exercise had a lower level of BMI than who did not exercised. Family support was significantly related to exercise behavior. The research suggested that there is a increasing responsibility for school nurse to instruct on the body shape and weight control behaviors through health education and consultation. Also, the results suggested that it is important to develop proper diet and exercise methods for adolescents girls to maintain their weight and health.

This research was conducted to examine the awareness and preference levels related to MSG (monosodium glutamate) according to well-being dietary life pursuit attitude factors as well as to improve opportunities to meet value conscious consumption of well-being-oriented customers. According to well-being dietary life pursuit attitude factors, respondents were divided to three clusters, indifference type, well-being-oriented type, and active health action type. Sensory evaluations were carried out on soybean paste soup (Doenjang-guk) and seasoned spinach with different levels of MSG. In the results, 74.4% of all respondents preferred Doenjang soup with 2% MSG, 65.4% preferred seasoned spinach with the same ratio of MSG, and 35.9% preferred seasoned spinach with 0.5% MSG. Regarding the acceptance level of MSG, addition of MSG to improve taste was acceptable to the indifference type (cluster 1). On the contrary, active health action type did not prefer MSG, wanted natural seasonings despite high prices, and preferred to dine at restaurants that serve MSG-free foods. Based on this study, restaurant companies should segment their customers on the basis of MSG usage and establish their positioning strategies according to their concepts.

Objectives: The aim of this study was to investigate the correlation between the obesity rate in elementary school students in Daejeon and the relevant factors such as social-demographical factors, genetic factors, birth factors, diet factors and intelligence factors. Methods: For the research, 443 fourth grade students, 405 fifth grade students and 417 sixth grade students from six elementary schools in Daejeon Metropolitan City Participated in this study and classified into three groups: normal-weight group, mild obesity group, and moderate or severe obesity group. Results: The total obesity rate of the elementary school students in the school district of Daejeon Metropolitan City was 14.2%; the rate of mild obesity was 7.2%; the rate of moderate obesity was 5.5%; and the rate of severe obesity was 1.5%. The obesity rate of surveyed boys was 16.9%, and the obesity rate of girls was 11.1%. The significant factors for girls' obesity were fathers' EMI, mothers' EMI, living standards, constant demand of foods, preference for greasy foods, frequency of eating snacks, and daily walking hours. It was found that students' subjective mind and objective health index were related to obesity. In the case of obese students, they had more concern about their health and more stress from the dissatisfaction of their physical appearance than normal students. Conclusions: From the above evidences, it is apparent that the obesity of elementary school students has strong relations with eating habits rather than physical activities. It is to be hoped that obesity prevention programs such as effective meal guidance. parental guidance for watching TV, and intense physical activities will be included in the curriculums of health education for elementary school students.

Purpose: The purpose of the study is to identify differences in BMI between early and late elderly people, and factors having influence of them. Methods: This study is an analysis of secondary data that used the raw materials from the KNHANES from 2008 to 2010. The subjects involved in the final analysis were 4,772 elders aged 65 or higher. Descriptive statistics, $x^2$-test and F-test, and CSGLM from the complex sample design were used for the data analysis with SPSS/WIN 19.0. Results: Significant differences were observed in the socio-demographic characteristics, health behaviors and diet habits between early and late elderly people. Adjusted for gender, location of residence, and living alone, the factors that affected BMI of the early elderly people included current smoking status, number of disease, difficulty in chewing, and number of meals per day while those that affected BMI of the late elderly people were current smoking status, number of disease, self-rated health, and difficulty in chewing. Conclusion: The study concludes that we should consider age-specific traits for monitoring the weight status of the elderly and providing appropriate weight management programs for the elderly.

In the past few decades, great progress has been made on understanding the interaction between nutrition and health status. But despite this wealth of knowledge, health problems related to nutrition continue to increase. This leads us to postulate that the continuing trend may result from a lack of consideration for intra-individual biological variation on dietary responses. Precision nutrition utilizes personal information such as age, gender, lifestyle, diet intake, environmental exposure, genetic variants, microbiome, and epigenetics to provide better dietary advices and interventions. Recent technological advances in the artificial intelligence, big data analytics, cloud computing, and machine learning, have made it possible to process data on a scale and in ways that were previously impossible. A big data platform is built by collecting numerous parameters such as meal features, medical metadata, lifestyle variation, genome diversity and microbiome composition. Sophisticated techniques based on machine learning algorithm can be used to integrate and interpret multiple factors and provide dietary guidance at a personalized or stratified level. The development of a suitable machine learning algorithm would make it possible to suggest a personalized diet or functional food based on analysis of intra-individual metabolic variation. This novel precision nutrition might become one of the most exciting and promising approaches of improving health conditions, especially in the context of non-communicable disease prevention.

Purpose: The purpose of this study was to identify the relationship between self efficacy (SE), health promoting behaviors (HPB) and symptoms of stress (SOS) among university students. Method: Data was collected by questionnaires from 369 university students in Seoul, Korea. Data was analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. Results: The mean score for SE was 3.42, the mean score for HPB was 2.48, and the mean score for SOS was 2.31. The score of SOS showed a significantly negative correlation with the score of SE (r=-.24, p=.00) and HPB (r=-.13, r=.00). Also, SOS showed a significantly negative correlation with diet HPB (r=-.15, p=.00), spiritual growth HPB (r=-.17, p=.00), interpersonal relationship HPB (r=-.17, p=.00), and stress management HPB (r=-.10, p=.04). The most powerful predictor of SOS was SE and the variance was $10\%$. A combination of SE, diet, problems related to drinking, and responsibility for health HPB account for $16\%$ of the variance in SOS among university students. Conclusion: This study suggests that SE and HPB are significant influencing factors on SOS among university students.
