This study was conducted to provide basic data for development of a dietary education textbook and guidebook by investigating and analyzing eating behavior, nutrition knowledge and educational needs in elementary school students. Most of the subjects were eating three meals a day (71.5%) and breakfast (75.3%). The percentage of students who consumed proper amount of meals (49.2%) was low. The percentage of students consuming salty food and fatty foods was 28.6% and 42.1%, respectively. The consumption of meat, fish, egg, bean and tofu was high, while the consumption of vegetables, fruits and seaweed was low. The percentage of students consuming processed food was high, but the percentage reading nutrition labels (34.9%) and hazard analysis critical control point (HACCP) mark (26.9%) when buying processed foods was very low. Total scores of eating behavior and nutrition knowledge were significantly higher in female students than in male students (p < 0.05-p < 0.001). The desirable frequency of the education was once a week (60.5%). The most preferred educational method was 'experiment and cooking practice' (40.1%). The students wanted dietary information as 'cooking' (39.0%). As a result of this study, many problems were found in the eating behavior of students and nutritional knowledge was observed to be low as well. On the other hand, the demand for dietary education was very high. The findings of this study suggested the need for developing dietary education programs in order to encourage proper eating habits of students.

Objectives This paper aims to understand the emotional-biological pathogenesis of eating disorders, and translate the understanding into new brain directed treatments. Methods The first part of the review sets the eating behavior into the context of what is now understood about the central control of appetite and molecular biology. The second part of the review sees how emotion relates to the brain circuit involving eating disorders. Results In general, patients with anorexia nervosa restricting type were less sensitive to reward, whereas patients with bulimia nervosa and anorexia nervosa binge purging type were more sensitive to it. The emotional life of people with eating disorders centers on food, weight, and shape. The abnormalities in social and emotional functioning both precede and persist outside of eating disorders. Conclusions Research into understanding the biological framework of the brain in eating disorders suggests that abnormalities may exist in emotional and information processing. This aspect can be translated into novel brain-directed treatments, particularly in anorexia nervosa.

Purpose: This study investigated the relationship between 3 major constructs of the theory of planned behavior (TPB), i.e., attitude, subjective norms and perceived behavioral control (PBC) and past experience of healthy eating and intentions of healthy eating in the short-term and long-term in adults living in Shanghai and parts of Anhui Province, China. Methods: The online study questionnaire for this cross-sectional study was based on previously validated items. A total of 408 Chinese adults (aged 18-64 years) residing in Shanghai and parts of Anhui Province, China were included to examine relationships between 3 major constructs of TPB and past experience of healthy eating, and short-term and long-term intentions of healthy eating. Multiple linear regression model adjusted for age and body mass index (BMI) was employed to test relationships. Results: Only PBC among 3 major constructs of TPB was significantly related to short-term (p < 0.001) and long-term (p = 0.002) intention of healthy eating after adjustment for age and BMI. Past experience of healthy eating was more significantly related to long-term intention (p < 0.001) compared to short-term (p = 0.020) intention of healthy eating. The short-term and long-term intention models explained 70.5% and 48.8% of the variance, respectively. Conclusion: PBC is a potential determinant of both short-term and long-term behavioral intention of healthy eating regardless of past experience of healthy eating in adults residing in Shanghai and parts of Anhui Province, China. Our results indicate that programs promoting healthy eating to Chinese adults incorporate PCB to perform healthy eating under his or her control.

This study was performed in order to compare the differences in dietary self-efficacy and eating behaviors as well as the relationship of weight control attitudes according to eating disorder perception and obesity index for high school girls majoring in dance. Almost half (45.5%) of the subjects perceived eating disorders, and the rate of underweight group was 45.7%. Forty-four percent of the group that perceived eating disorders were in modern dance, while 55.0% of the group that did not perceived eating disorders were in Korean dance (p < 0.05). For the obesity index, a similar rate was shown between the different types of dance for the underweight group, but in the normal group, 54.5% were in Korean dance (p < 0.05). Most (82.0%) of the group that perceived eating disorders had fears on obesity, while only 53.3% of the non-perceiving group had fears on obesity (p < 0.01). Over half (58.3%) of the underweight group had fears on obesity, while 77.2% of the normal group showed fear in that (p < 0.05). For necessity of weight loss to do dance performances, 25.0% of the underweight group and 57.9% of the normal group need that (p < 0.05). Most of the group that perceived eating disorders (92.0%) answered that they had experience in very low calorie diets, while only 40.0% of the non-perceiving group had experience (p < 0.001). For necessity of calorie education, 42.0% of the group that perceived eating disorders and only 20.0% of the non-perceiving group answered is needed (p < 0.05). For eating behavior, the group that perceived eating disorders had lower total scores compared to the non-perceiving group (p < 0.001), The group that perceived eating disorders showed lower scores for restraint eating (p < 0.01) and emotional factors (p < 0.001) except by external eating. This study showed that high school girls majoring in dance have high interest in weight control and problems with wrongful body images and eating behaviors, as well as need for calorie education were suggested. Thus, it is necessary to develop and execute a proper weight control education program for the subjects. (Korean J Community Nutrition 14(4) : 383${\sim}$391, 2009)

Purpose: Eating behaviors are influenced by food environments, such as availability and/or accessibility of healthy food options. In this study, we examined the relationship between healthy eating-out options and the intention to eat healthily in adults residing in Daqing, China, using an extended theory of planned behavior (TPB). Methods: Data were collected via an online survey conducted from April to May 2021 using a previously validated questionnaire in Daqing. A total number of 308 subjects aged 18-64, either Daqing oilfield workers or their family members were eligible and finally included in the analysis. The relationships among the attributes and the quality of healthy eating-out options, the three major constructs of TPB, and the intentions of healthy eating were examined using multiple linear regression analyses. Results: Subjective norms (p = 0.049) and perceived behavioral control (PBC) (p = 0.000) were significantly related to the healthy eating intention. The quality and attributes of the food served statistically significantly explained the intention to eat healthily. After controlling for age, sex, and body mass index, not the quality but the attributes of food served (p = 0.037), subjective norms (p = 0.016), and PBC (p = 0.000) had a significant relationship with the intention to eat healthily. The model explained 83.7% of the variance. Conclusion: The healthy eating-out choices, along with subjective norms and PBC of TPB, may be a potential determinant of healthy eating intention among Chinese adults living in Daqing, China. Policy implications have highlighted that not only the personal intention to eat healthy foods, but also the available healthy food environment may be important for the choice of healthy options by the population of interest. Therefore, building an environment for healthy eating choices and campaigns aimed at increasing consumer awareness of healthy eating are equally important for a smart eating choice.

The aim of this study was to construct and test a structural equation model for the risk factors of metabolic syndrome in Korean adults. The structural equation model hypothesizes that eating alone and feeling depressed is a risk factor for metabolic syndrome. The data of this study were obtained from the Sixth Korea National Health and Nutrition Examination Survey which was cross-sectional data from the representative national survey. A total of 4,013 subjects replied to the survey item of lifestyle and completed the physical examinations among adults aged 19 years or older in South Korea was in 2015. The structural model in this study was composed of four latent variables: eating alone, depression, negative health behavior, and metabolic syndrome. Two variables, the rate of eating alone and depression, were exogenous variables. Negative health behavior was both a mediating variable and endogenous variable, and metabolic syndrome was the final endogenous variable. The data were analyzed using the Maximum Likelihood method and bootstrapping. The structural model was appropriate for the data based on the model fit indices. The results of this study can be summarized as follows: Eating alone is a direct risk factor of metabolic syndrome in Korean women. Depression can mediate metabolic syndrome through negative health behaviors. Negative health behavior had a direct impact on metabolic syndrome in both men and women. This study may be a guideline for interventions and strategies to reduce the incidence of metabolic syndrome in Korean adults.

A study was conducted to investigate the effects of methods of feeding a total mixed ration (TMR) on behavior patterns of growing Hanwoo steers. A total of 15 growing steers (13 months old) were assigned to the control (fed roughage and concentrate mix separately), TMR1 (fed restricted TMR), and TMR2 (fed TMR ad libitum) groups. Individual behaviors of steers were observed for 48 hours. Compared with the control, feeding restricted TMR (TMR1) resulted in short eating time, long ruminating time, short chewing time, high frequencies of defecation, urination, and drinking of water, great numbers of boluses and chews, long ruminating time per bolus, low feed value index, high eating and chewing efficiencies (p<0.05). Compared with feeding restricted TMR (TMR1), feeding TMR ad libitum (TMR2) resulted in 1.2 kg more daily feed DM intake, long eating and chewing times, short resting time, great frequencies of defecation, urination and drinking of water, more numbers of boluses and chews, long ruminating time per bolus, low feed value index, low eating and high ruminating efficiencies (p<0.05) and similar chewing efficiency (p>0.05). Considering all these results, the wet TMR feeding system induced generally more desirable eating and ruminating behaviors of growing Hanwoo steers, but made the barn floor wetter due to more defecation and urination.

The objective of this study was to evaluate college students’dietary and health behaviors in relation to their Myers-Briggs Type Indicator (MBTI) personality preferences. Dietary and health behaviors were surveyed for 444 college students who performed the MBTI personality test. Only 6.1% of the subjects regularly had three meals a day, while 27.1% ate breakfast every day. Fifty-six point nine percent of the students took less than 15 minutes to eat a meal and had the habit of eating fast. The number of food groups they ate was, on average, 2.74 and was eaten mainly at dinner. This showed that college students did not eat a large variety of foods. Eighty-two percent of the subjects drank alcoholic beverages, 21.4% smoked, and 69.3% exercised. In addition, 73.9% of them were not satisfied with their body image, but they were not eager to try weight control. There were not many significant differences between Extraversion (E)-Introversion (I), Sensing (S)-iNtuition (N), and Thinking (T)-Feeling (F) in their dietary and heath behaviors, although some gender differences existed. Significantly better dietary and health behaviors were shown in subjects preferring Judging (J) rather than Perceiving (P). There behaviors included eating breakfast, regularly eating three meals a day, smoking less, exercising more and having a lower tendency to night-eating. The personality preference of J-P could be useful index for nutritional education and counseling or behavior modification programs for obese people.

This study was conducted to compare the eating habits of disabled and non-disabled children in Seoul and Gangneung. Korea. Questionnaires about eating habits were answered by the children's parents and their teachers. The subjects of this study consisted of 146 disabled children (108 boys and 38 girls) from two special education schools and 241 non-disabled children (control group,120 boys and 121 girls) from two elementary schools in Seoul and Gangneung, respectively. The percentage of the children who required more than 30 minutes to eat was 11.3% in the disabled group and 2.5% in the non-disabled group. In the disabled group,44.0% ate excessive amounts of food or could not control their intake. The percentage of the children whose frequency of eating breakfast was less than 1 to 2 times per week was 21.0% in the disabled group and 9.7% in the non-disabled group. Also, 7.6% of the disabled group and 13.9% of the non-disabled group had snacks more than three times per day. The percentage of children who were able to eat by themselves was lower in the disabled group (47.9%) than in the non-disabled group (87.8%). Of the remainder of the disabled group,28.6% spilled food, and 14.3% needed the aid of others when picking up side dishes. The percentage of parents who worried about their children's eating an unbalanced diet was 48.5% in the disabled group and 41.8% in the non-disabled group. In addition, there were problems with eating behaviors in 22.7% in the disabled group, and with under-eating (15.9%) and with excessive intake of instant foods (16.8%) in the non-disabled group. These results suggest that the eating habits and eating behaviors of disabled children are different from those of non-disabled children. Thus, nutritional educational programs and educational materials for disabled children and their parents should be developed.

The purpose of this study was to investigate weight control attempts and related factors among 209 middle school female students in Daejeon. Variables examined were body satisfaction, beliefs regarding weight control, body image, nutrition knowledge, nutritional attitudes, dietary behavior and dietary intake. A cross-sectional survey was employed, and data was analyzed using t-test and chi-square teat (at $\alpha$=0.05). The average height, weight, and body fat (%) of subjects were 160.2cm, 52.4kg, and 25.9%, respectively. Those who attempted weight control were 61.7% of the samples, suggesting that weight control was quite popular among adolescents. Students in the weight control attempt group were more satisfied with their body size (p<0.001), and showed more distorted body image than those in the no weight control attempt group (p<0.001). Most of beliefs regarding weight control were also different in the two groups. The attempt group believed more strongly in the advantages of weight control, and believed less strongly in the harmful effects or difficulties associated with weight control. Although there were no differences in nutrition knowledge in the two groups, nutritional attitudes were slightly more favorable in the attempt group (p<0.01). In contrast, eating behaviors, such as those related to caloric intake (p<0.001), body image (p<0.001), and specific situations (p<0.01) were more desirable in the no-attempt group than in the attempt group. In addition, dietary intake of the attempt group was less adequate than that of the no-attempt group for nutrients such as iron (p<0.01), vitamin A, thiamin, riboflavin, and vitamin C(p<0.05). This study suggests that adolescents who attempt control weight have a more distorted body image and inadequate diet and showed more undesirable eating behaviors. Students should be taught and practice desirable methods of weight control. Educational programs should also include strategies for changing beliefs regarding weight control, as well as modifying diets and eating behaviors.
