The purpose of this study was to investigate eating behavior, nutritional status and health condition of obese adult attending a weight control exercise. The subjects of this study consisted of 81 adult in some areas of Daegu. Their weight, height, triceps, midarm circumference were measured and their dietary intake and eating behavior were obtained by using questionnaires. Anthropometry was conducted to determine obesity. Average age of men and women were 38.1 and 35.2 years old respectively. Their intake of energy and protein were 69.5% and 97.4% of RDA respectively. Energy intake of normal and obese group was 74.4% and 64.9% of RDA respectively. Protein intake of normal and obese group was 99.7% and 95.3% of RDA respectively There was a negative correlation between PIBW and energy intake, PIBW and carbohydrate intake, BMI and energy intake, and BMI and carbohydrate intake. A relative magnitude of factors affecting weight decrease rate was analyzed by Stepwise multiple regression analysis. Overall results about relative influence of independent variables to dependent variable(weight decrease rate) indicated that the BMI(p<0.01) was the most significantly correlated with weight decrease rate in all subjects. The results of this study suggest that the extensive nutrition education in weight control program should be emphasized to prevent obesity early.

BACKGROUND/OBJECTIVES: This study examined the differences in psychosocial factors and eating behaviors by the stages of change (SOC) in nutrition management among elementary and middle school athletes. SUBJECTS/METHODS: Subjects were young athletes recruited from the athletic clubs of 10 organizations. Subjects responded to a survey questionnaire, and data on 167 athletes were analyzed. Subjects were grouped into the pre-action or action stage in nutrition management. The χ² test, t-test, analysis of covariance, and correlation analysis were used in data analysis. RESULTS: Athletes in the action stage (62.3%) compared to the pre-action stage, showed a higher self-efficacy (P < 0.01), and felt more confidence in performing specific eating behaviors (P < 0.05 to P < 0.01). Those in the action stage had more favorable beliefs regarding nutrition (P < 0.001) and agreed less strongly on the specific misconceptions/disadvantages of nutrition (P < 0.01) than those in the pre-action stage. Eating behaviors (P < 0.001) and subscales of the eating behaviors (P < 0.05 to P < 0.01) also differed significantly by the SOC group. Place of eating dinner (P < 0.05) and the person who prepares dinner (P < 0.05) showed significant differences by the SOC group. The relationship of self-efficacy, beliefs regarding nutrition, and eating behaviors to the SOC differed by sports type. Beliefs for football athletes, self-efficacy, and beliefs for baseball athletes were correlated significantly with the SOC, whereas all 3 variables were related to the SOC for handball and other athletes. CONCLUSIONS: This study showed differences in psychosocial factors and eating behaviors between the pre-action and action stages. Nutrition education should include strategies to help young athletes modify their beliefs, mainly misconceptions/disadvantages of nutrition, increase self-efficacy, and adopt specific and desirable eating behaviors. Nutrition education might employ different strategies considering the sports type that student-athletes participate.

The purpose of this study was to determine the factors related to eating behavior of breakfast and dietary life score in elementary, middle, and high school students. This study was conducted by administering questionnaires, and data were analyzed by the SPSS program. The subjects were divided into three groups according to school group (elementary, middle, and high school). The subjects consisted of 1,879 students (male 973, female 906) from 11 schools in Kyungpook. The distribution of subjects was as follows: elementary school children 682, middle school students 702, and high school students 495. The results are summarized as follows. Dietary life score was 72.64 for elementary school students, 64.77 for middle school students, and 62.67 for high school students. Frequency of eating breakfast and reasons for skipping breakfast were significantly different according to school group (P<0.001, P<0.01, respectively). The main reason for skipping breakfast was 'habitual skip' for elementary and middle school students (54.8%, 46.7%) and 'getting up too late' in high school students (55.4%). There were no significant association between frequency of eating breakfast and BMI. However, there were significant differences in school performance and sleeping hours according to frequency of eating breakfast (P<0.001, P<0.01, respectively). Dietary life score was significantly different according to frequency of eating breakfast (P<0.001). These results stress the need for intervention programs aimed at decreasing the frequency of skipping breakfast in children and students at school. Further, those who prepares meals for children must increase their concern about preparing breakfast.

Purpose: This study was conducted to define factors influencing health-related quality of life (HRQOL) in women undergraduates. Independent variables of physical activity, attitude to eating, satisfaction with body shape, stress and self-esteem were used to predict HRQOL. Method: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Participants were 245 women undergraduates who were recruited from July to September 2012. Result: The mean for the physical component summary (PCS) of HRQOL was 73.89, and for the mental component summary (MCS) was 68.45. There were significant correlations between attitude to eating, satisfaction with body shape, stress, self-esteem and the two components of HRQOL. The groups with minimal or health enhancing activity were significantly higher in PCS and MCS than the inactivity group. Stepwise multiple regression analysis indicated that 35% of the variance in PCS was significantly accounted for by self-esteem, perceived stress, attitude to eating, and physical activity, and 45% of the variance in MCS was significantly accounted for by perceived stress, self-esteem, attitude to eating, and satisfaction with body shape. Conclusion: The results indicate that these factors influencing HRQOL should be considered when developing programs to improve HRQOL for women undergraduates.

Purpose: This study aimed to examine the association between depression and eating behavior factors in Korean adults. Methods: Study subjects were selected (n = 5,103) from the participants of the 7th Korea National Health and Nutrition Examination Survey 2018 and divided into depression (men, 59; women, 162) and normal groups (men, 2,083; women, 2,799). Subjects with a Patient Health Questionnaire 9 score ≥ 10 (out of 27 points) were defined as having depression. Results: A higher prevalence of depression was observed in both men and women who were unemployed (p < 0.001, p = 0.008), had lower income (both p < 0.001), poorer subjective health (both p < 0.001), and poor food safety (both p < 0.001). The prevalence of depression was higher in women with lower education levels (p = 0.008), who were unmarried (p = 0.010), smokers (p < 0.001), and in a one-person household (p = 0.001). Obese men showed a higher prevalence of depression (p = 0.009). Men who were eating alone or skipping lunch had a high prevalence of depression (p = 0.009), while women who were eating breakfast (p = 0.012), lunch (p = 0.001), and dinner (p = 0.010) alone had a high prevalence of depression. The relationship analysis between men and women according to dietary habits using logistic regression showed that, in women, after variable adjustment, skipping lunch (odds ratio [OR], 2.677; 95% confidence interval [CI], 1.090-6.574), meal frequency of 2 times per day (OR, 1.658; 95% CI, 1.084-2.536), and lunch frequency of 3-4 times per week (OR, 3.143; 95% CI, 1.725-5.728) were significantly associated with a higher prevalence of depression. Conclusion: Depression in women was not only affected by more sociodemographic variables but also associated with decreased frequency of lunch and dinner, especially with skipping lunch.

Individual lifestyle and eating habits have changed rapidly due to the evolution of society. Especially, climate change caused by industrialization has influenced society, with the result that today's consumers perceive sustainability to be an important value. The purposes of this study were to segment consumers on the basis of their food-related lifestyle and to explore climate-friendly food consumption behavior by considering factors such as moral intensity, propensity for disgust with meat as well as consumer characteristics. The results of this study were as follows: first, consumers were segmented into three groups(high involvement, low involvement, convenience oriented). Consumers in the high involvement group presented a higher level of moral intensity and climate-friendly food consumption behavior than the other groups. Furthermore, factors influencing the selection of climate-friendly food were found to differ according to the type of consumer. Consumers in the high involvement group were found to be significantly influenced by age, concentration of effect, the morality of eating meat and meat texture, while consumers in the low involvement were found to be significantly influenced by social consensus and the morality of eating meat. Finally, consumers in the convenience oriented group for food life were found to be significantly influenced by age, harm perception, and the morality of eating meat.

Objectives: The aim of this study was to evaluate the effects of a lifestyle modification program for Korean adults with cardiovascular disease risk factors on their health behaviors and health status. Methods: A total of 448 adults with abdominal obesity and additional cardiovascular disease risk factors(high blood pressure, low HDL-cholesterol, high triglyceride or high blood glucose) were randomly assigned to either an intensive intervention group (IIG, n=216) or a minimal intervention group(MIG, n=232). Participants in the IIG received lifestyle modification program which consisted of health counseling with nutrition assessment, health booklet and health diary, while those in MIG received minimal information. Results: The participants in the IIG significantly improved dietary habits(p<.05), retrained eating(p<.001), external eating(p<.01) behaviors, leisure time physical activity(p<.05), dietary self-efficacy(p<.01), exercise self-efficacy(p<.01) and MetS score(p<.001) after 3 months. In addition, the participants in the IIG showed more improvement in dietary habits(p<.05) compared with those in the MIG. Conclusion: The lifestyle modification program was effective in improving some health behaviors, behavioral determinants and cardiovascular risk factors for a short term.

In this study, focus group interviews were used to investigate female university students' eating behavior, factors related to eating behavior, information sources for nutrition, and formats for nutrition education. Thirty-six students participated in one of five focus groups during December 1998 in Seoul. Focus group discussions were video, audio-taped, transcribed and analyzed by major themes. Results showed that subjects have undesirable eating behaviors, such s eating irregular meals and skipping meals. These behaviors are caused by a lack of time, habit, or for the purpose of losing weight. The students tended to have unbalanced diets and frequently ate out. They had a large amount for dinner and frequently snaked when stressed or had an empty stomach. Most of them were interested in weight control and had attempted to lose weight, but they did not participate in regular exercise. The most frequently used source for nutrition information was the mass media, but much nutrition information was based on what they learned from home economics class during middle to high school. They received more support from mothers, elder sisters, and friends for eating behaviors, such s lowering caloric intake and losing weight. In nutrition education, they wanted to learns behaviorla skills to adopt healthy behaviors, including meal planning, applying scientific weight control methods, exercise that fit into their lives, and stress management. They also mentioned that nutrition screening and assessment should be a part of nutrition education programs. As a method for nutrition education, subjects preferred an individualized approach to group education. These results provide the qualitative information for developing nutrition education programs which will be implemented for Korean University students.

Judging from the studies carried out by Dr. Jo, Yong Jin on the Koreans' faces, Koreans divided into two constitutions according to their facial features and heritages. The one population is the Northern lineage whose ancestor migrated from Siberia in ice age. In order to survive in cold climate, they have developed a high level of metabolic heat production. Cold adaptation for preventing heat loss results in a reduction in the facial surface area with small eyes, nose and lips. The other population is the Southern lineage who is the descent of native in Korean peninsular. They have big eyes with double edged eyelids, broad nose and thick lips. It is generally believed that both genetic and environmetal factors influence eating behaviors. Although we can't recognized their heritage that may contribute to the metabolism and eating behavior, we commonly recognize their physiological heritage acceding to their facial features. In order to investigate the relationship among the size and shape of facial feature, the eating behavior, anthropometric measurement in female college students, the eating behaviors was measured during an instant-noodle lunch eaten in a laboratory setting at the ambient temperature of $23^{\circ}C$. The anterior surface area of left eye and length of right eye were positively correlated with the difference between the peak postprandial and the meal-start core temperature. The surface area of lower lip also negatively correlated with the meal-start core temperature and meal duration. In addition, the total lips' area was positively correlated with the difference between the peak postprandial and the meal-start core temperature and negatively correlated with the meal duration. However anthropometric measurements were not related with the size of facial features.

Objectives: This study was conducted to compare health behavior between obese children and those with standard body weight, analyzing the correlation in their health behavior, and further making it useful data for the development of programs for a better education on health. Methods: To achieve the goal of this survey as mentioned, we have carried out a research targeting on a total of 636 elementary school students, 505 children of standard body weight and 131 children of obesity, all of whom belong to elementary school students in Seoul, the capital city of Korea. And we have itemized the research into 'eating habits', 'physical activity, 'dieting experience in the past', and 'stress and release management' in order to spot the specific health behavior leading to obesity. Results: 1. Factors for diseases mainly from obesity were statistically significantly differentdepending on degree of the subjects' self-respect and a history of obesity in their families, father($x^2$=7.172, p=.007), mother($x^2$=9.011, p=.003), and siblings($x^2$=12.431, p=.000). 2. Regarding the subjects' eating habits, some items were statistically significantly different: taking algae($x^2$=3.324, p=.043), eating breakfast($x^2$=6.070, p=.010), and eating fast($x^2$=8.551, p=.002). 3. There were some statistically significant differences in the subjects' dieting experience. For the latest 1 year, they made some attempts for that: fasting($x^2$=4.229, p=.040), reduction of eating($x^2$=25.377, p=.000), eating one meal a day($x^2$=5.582, p=.018) 4. OR(Odd Ratio)of Percieued obesity was 0.15 in the subjects' under weight than normal weight. And there was OR(Odd Ratio) 11.72 in the subjects' over weight. We can witness obese children think that they are over weight(p=.000).
