The subjects was 415 participants of the 10 weeks (20 time participation program). The data was collected by basic somatometry and HRV (Heart Rate Variability) / APG (Accelerated Plethysmograph) Analyzer. The average age, height, weight and BMI were 28.6 years, 162.1 cm, 62.8 kg and 23.9 $kg/m^2$, respectively. Their body types by BMI were under weight (1.2%), normal (45.8%), overweight (24.8%), mild obesity (22.7%) and obesity (5.5%). There were significant reductions of average weight (4.6 kg) and average BMI (1.75 $kg/m^2$) on the 10th week. There were positive changes in vascular age (50.4%), stress index (44.6%), fatigue index (43.9%), health index (54.5%) of the subjects during the program. There was a meaningful difference of the average variation for the vascular age, stress index, fatigue index, and health index between two groups; one improving the eating habit and the other did not (p<0.05), and also there was a meaningful difference of the average variation for the fatigue index in both groups improving the sleeping habit (p<0.05), but was not a meaningful difference of the average variation for the vascular age, stress index, and health index between two groups. There was a meaningful difference of the average variation for the vascular age, stress index, fatigue index, and health index between two groups improving both eating and sleeping habit (p<0.05). In conclusion, the weight loss program was effective on the weight loss and BMI reduction and health related indices.

The present study was conducted to investigate the relation of eating behavior and food intake to 534 adolescents' obesity indices. Group means of relative body weight (RBW) were 93.66 for males and 97.12 for females. Body mass index(BMI) were 20.39 for males and 20.41 for females. Respondents were divided into 3 groups on the basis of RBW as an obesity index. Astonishingly, 44.76% of total respondents were underweight and 12.92% overweight and obese. 64.54% of respondents usually skipped their breakfasts and 24.23% their dinners. More males did not have their breakfasts than females. In contrast, more females skipped their dinners than males. A significant difference was found between males and females in their eating habits(p<.001) that should be changed. As their undesirable eating habits, males pointed out 'skipping meals', while females stressed 'overeating'. There were more overeating respondents in the overweight group, while more respondents skipping their meals were found in the underweight group. Many females(72.79%) and males(52.78%) tended to alternate consistently overeating and fasting to lose weight. The most important reason for losing weight was to improve their appearance(61.12%). In addition, nutrient score indices of respondents were very low with a mean of 33.39. Only 42.13% of total respondents showed good nutrient score indices. More males ate meat, bean, white vegetables, potato and fat than females(p<.05), whereas more females ate bread, rice cake and fruit than males(p<.01). Among the 3 groups -overweight, normal weight and underweight groups, overweight group was the most eaters of meat, fish, egg and milk; underweight group was the least eaters of them.

Objectives: Study purpose was to investigate perception on diet, diet problems and related factors among young adult women using focus group interviews (FGI) based on the Social Cognitive Theory (SCT). Methods: Eight groups of FGI were conducted with 47 female undergraduate or graduate students. Guide for FGI included questions regarding perception on optimal diet, diet problems and cognitive, behavioral, and environmental factors of SCT. FGI were video, audio-taped, transcribed and analyzed by themes and sub-themes. Results: Subjects showed irregular eating habits (skipping breakfast, irregular meal time) and selection of unhealthy foods as the main diet problems. Regarding cognitive factors related to optimal diet, subjects mentioned positive outcome expectations (e.g., health promotion, skin health, improvement in eating habits, etc.) and negative outcome expectations (e.g., annoying, hungry, expensive, taste). Factors that promoted optimal diet were mainly received from information from mobile or internet and access to menu or recipes. Factors that prevented optimal diet included influence from friends, lack of time and cooking skills. Behavioral factors for optimal diet included behavioral capability regarding snacks, healthy eating and smart food selection. Subjects mentioned mass media (mobile, internet, TV) as the influential physical environment, and significant others (parents, friends, grandparents) as the influential social environment in optimal diet. For education topics, subjects wanted to learn about healthy meals, basic nutrition, disease and nutrition, and weight control. They wanted to learn those aspects by using mobile or internet, lectures (cooking classes), campaign and events. Conclusions: Study results might be used for planning education regarding optimal diet for young adult women. Education programs need to focus on increasing positive outcome expectations (e.g., health) and behavioral capability for healthy eating and food selection, reducing negative outcome expectations (e.g., cost, taste) and barriers, making supportive environments for optimal diet, and incorporating topics and methods found in this study.

The aim of this study is to survey the eating habits and nutritional knowledge of children in Pusan, with a view to uncovering problems and their underlying causes and cultivating desirable dietary habit and nutrition for children. Three hundred and fifty six elementary school students were asked questions about their eating habits and nutritional knowledge as well as general information about their personal characteristics. The results showed: 1. Only 53.5% of the subjects had breakfast every day. Seventy-six percent of the subjects had dinner every day. Only 40% of the children took meals and talked with family at both breakfast and dinner. Thus there was little opportunity for dietary guidance by parents. 2. About half of the subjects answered that their appetite decreased after eating snack foods between meals. A third of the subjects liked the baked goods as snacks. Because of their high sugar and fat content, they can damage children's health, resulting in child diabetes and tooth decay. For this reason, careful education is necessary to allow children to be able to select snack foods that are appropriate in kind and quantity. 3. About 85% of the subjects had an unbalanced diet. Therefore systematic nutrition education at school is necessary to instill in children the value of balanced diet. 4. Children preferred rice to other cereals as a staple food. They disliked kimchi, seasoned and blanched foods and salads as subsidiary foods. It is therefore necessary to teach children systematically the nutritional advantage of cereals and vegetables and to heighten their awareness of Korean food culture. 5. Children had a low level of nutritional knowledge. The knowledge of specific nutrients was lower than that of foods. In conclusion, systematical educational programs need to be developed at elementary school. These should include information about achieving a balanced diet, good eating habit, meal management and Korean dietary culture. Nutritional education at home must be emphasized.

This study was conducted to examine the nutritional knowledge and dietary habits by gender and a mother's employment status for middle school students. The subjects consisted of 423 students (212 boys and 211 girls). As for mother's employment status, 61.7% of the mothers were working, and 38.3% were housewives. The results from the analysis on differences of nutritional knowledge and dietary habits showed that girls tended to have a higher nutritional knowledge than boys (p<0.01). In terms of dietary habits, boys appeared to have more desirable eating habits than girls. As for the mother's employment status, only students whose mothers were doing housework tended to have higher nutrition knowledge and more positive dietary habits than students whose mothers were working. The influence of nutritional knowledge was found to have a significant effect on dietary habits (p<0.001). In addition, nutritional knowledge (B=0.168, p<0.01) turned out to have an influence on dietary habits, where a higher nutritional knowledge produced more positive dietary habits. Considering the results described above, nutritional knowledge appears to have a significant influence on dietary habits. Therefore, instructions on the importance of nutritionally well balanced meals must to be reinforced in nutritional education.

Objectives : This study examined the association between body mass index(BMI) and psychological factors; self-esteem, depression, restraint eating, disinhibition, and hunger. The difference of TFEQ(restraint eating, disinhibition and hunger) was analyzed in variety of current diet situations. Methods : The research was based on a sample of people who visited our website and submit the result of self test(self-esteem n=3183; TFEQ n=5167; BDI n=2457). Results : Self-esteem and BDI was slightly correlated with BMI. There is negative correlation between restraint eating and BMI and positive correlations were observed between hunger and BMI, and disinhibition and BMI. We studied diet situation and eating habits. We divided the sample into 4 groups in accordance with self-submitted result: non-diet group(n=2806), diet-failed group within 3 months group(n=371), maintaining group after successful-diet(n=233), on-going diet group(n=1757) As to restraint eating, non-diet group showed the lowest score in restraint eating and maintaining group after successful-diet showed the highest. The score in disinhibition and hunger was significantly lower in maintaining group after successful-diet group than one in diet-failed group. Conclusion : These results suggest that it would be essential to treat these psychological factors such as depression and self-esteem in weight loss program. Considering the result in diet-situation and TFEQ, we insist that restraint-eating and disinhibition should be controlled. If these psychological factors were not treated in place, even the successful diet might turn out to be a worse situation like binge-eating

The purpose of this study was to evaluate night time eating habits, dietary habits, and nutrient intake in university students according to residence type. A survey was conducted by administering questionnaires to 664 students. Questionnaire interview and 24-h dietary recall were conducted. Subjects were divided into three groups according to residence type: dormitory boarding (DB group, N=313), self-boarding (SB group, N=246), and living with parents (LWP group, N=105). Average ages in the DB, SB, and LWP groups were 21.3, 22.2, and 22.1 years, respectively. There were no significant differences in body mass index between the three groups. In total, 77.3% of students regularly ate night time snacks. The proportion of students who reported night time eating was 84.0% in the DB group, 73.6% in the SB group, and 65.7% in the LWP group (P<0.001). In terms of food types consumed during night time eating, the DB group showed a significantly higher rate of consumption of fried chicken and flour-based foods than the SB and LWP groups, whereas the SB group showed a significantly higher rate of consumption of alcohol beverages than the DB and LWP groups. Energy, carbohydrates, protein, fat, vitamins, and mineral intakes were significantly higher in the DB group than in the SB and LWP groups. In addition, intake of cholesterol per 1,000 kcal was significantly higher in the DB group than in the SB and LWP groups. Thus, SB and DB students seemed to have more night time eating problems than LWP students. Accordingly, nutritional education is needed to support the development of healthier eating habits, in particular, night time eating habits, among students living in dormitories and in self-boarding situations.
