Although adolescents' obesity prevalence increases recently in Korea due to Westernized dietary life, according to social and economic development, and physical activity decline, distorted body image and improper dietary habits are prevalent, because of excessive obsession with weight control, deriving from psychological impacts including appearance supremacy. This study conducted a survey on health oriented awareness and attitude related with dietary habits targeting adolescents, such as high school students and college students, younger than 24, from May 11 to May 29, 2015. In this study, 280 questionnaire copies were collected out of 300 distributed questionnaire copies, and used 269 copies as analysis data, except 11 copies of which responses were inadequate. The results of this study are as follows: First, the high school students showed higher dietary regularity than the college students. Especially, 95.5% of the college students showed very high irregularity of lunch, compared with just 4.5% of the high school students. Second, the adolescents showed distorted perceived body image in comparison with body mass index (BMI). As a result of examining BMI relationship, according to one's own perception on body type, 28.6% of the respondents perceived themselves fat, despite normal BMI, and 40.4% of the respondents perceived themselves normal, despite low BMI. Third, health behavior activities level was higher, as the regularity of breakfast (B=1.093), lunch, (B=0.650), and dinner (B=0.765) was higher. The variable affecting the most ( ${\beta}=0.372$) was the regularity of breakfast. As interest in weight control was higher, health behavior activities was lower. Because over-interest in weight control may be linked with improper dietary habits or weight control, a caution is needed. The results of this study are expected to be utilized as the basic data for the policy and health-oriented program development to improve adolescents' health behavior practice.

The purpose of this study were to investigate the influences of objectified body consciousness and body esteem on the weight and hair management behaviors of females. The questionnaires were administrated to 632 female residents of the Gwangju city, Korea. The SPSS for Windows 18.0 Statistics Package was used for data analysis. To verify the formulated hypotheses, descriptive statistical analysis, factor analysis, reliability analysis(Cronbach's ${\alpha}$), regression analysis, path analysis were used. The results were as follows. First, objectified body consciousness was divided into three factors: body shame, body surveillance, and appearance control beliefs. objectified body consciousness turned out to have positive influences on overall weight management behaviors and hair management behaviors. Second, objectified body consciousness appeared to have positive influence on overall body esteem. When the influences were further examined, body surveillance turned out to have significant positive influence on body esteem, whereas body shame and appearance control beliefs seemed to have few significant influences on body esteem. Third, body esteem appeared to have significant positive influence on all weight management behaviors and hair management behaviors. Fourth, it was found that objectified body consciousness had direct impact on the weight management behaviors and hair management behaviors without mediation body esteem.

Purpose : This study examines the differences in self-efficacy and health promoting behavior between obese students and normal weight students by gender; it tries to obtain basic data for the health guidance of obese students. Methods : Data were collected from 360 students (90 normal weight males, 90 obese males, 90 normal weight females, 90 obese females) using questionnaires about general characteristics, self-efficacy, and health promoting behavior. There were analyzed with descriptive statistics (frequency, percentage, mean, standard deviation), and a x$^2$ test, ANCOVA, and a Pearson's correlation of coefficient at the 0.05 significance level by using the SAS (version 8.01) Win Program. Results : The score of self-efficacy appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=25.85, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=.01, p=.9118). The score of health promoting behavior appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=28.61, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=1.25, p=.2643). The relation of self-efficacy and health promoting behavior shows a statistically significant correlation in all cases: obese boys (r=.69, p=<.0001), normal weight boys (r=.51, p=<.0001), obese girls (r=.67, p=<.0001), and normal weight girls (r=.49, p=<.0001). Conclusions : An evaluation study needs to see whether a program to encourage the self-efficacy of obese boys can be effective in health promoting behavior or weight control in the long run. As in this study more than half of the obese girls have mild-level obesity, a follow-up study should be conducted to examine the self-efficacy and health promoting behavior between middle or highly obese students and normal weight students.

The purpose of this study was to investigate the effects of eating habits and control of overeating of obese children on the body weight control program. The program included nutritional education, psychotherapy and physical exercise on weekly session for 9 months. The results of this study were as follows. Participants of the study involved 30 obese children attending elementary school. The average age of the children was 11.78 years, mean height and weight were 146.22cm and 50.61kg. The average BMI and body fat contents were 24.06 and 30.49% respectively and WHR of the children was 0.87. There was a significant difference between boys and girls' BMI(25.18, 23.31, p<0.01). As a result of the eating habits test, 50% of the subjects showed low level of regularity of diet, and 76.7% of the subjects showed high level of balanced diet score. Large portion(83.3%) of the subjects had high level of healthy behavior score. WHR of girls significantly decreased from 0.86 to 0.82(p<0.01) after the body weight control program. There were no significant differences in serum components of the obese children after the program. When regarding the score of eating habits in relation to obesity indices, the WHR significantly decreased(p<0.05) in a group of children with high eating habits score. Also in the group of overeating controls, significantly decreased WHR(p<0.05). In the results of correlation analysis, body weight was positively correlated with BMI(r=0.624), the level of total cholesterol(r=0.5109) and HDL cholesterol(r=0.5088). The score of healthy behavior was positively correlated with height(r=0.5286) and negatively correlated with the level of LDL cholesterol(r=0.3555) and WHR(r=0.4028) These results suggest that the body weight control program must be considerate of the different groups of children with different scores in the eating habits and overeating controls test.

Purpose: This study identified the effects of body weight control behaviors on bone mineral density (BMD) in Korean women aged 20 to 39 years. Methods: A secondary analysis of the 5th Korean National Health and Nutrition Examination Survey was conducted. Asian-Pacific criteria of BMI (Body Mass Index) and BMD were calculated for 1,026 women selected. The effects of body weight control behaviors were assessed using binary multiple logistic regression analysis while controlling for BMI. Results: Osteopenia and osteoporosis rates were 32.8% and 2.0%, respectively. About 69% of women performed weight control behaviors, and a combination of diet/exercise (22.7%) and drug added methods (10.9%) for weight control. Women who performed both diet control and exercise had a lower possibility to have abnormal BMD than those who did not try weight control (OR=0.67, CI=0.45~0.98, p=.039). Further weight control behaviors did not influence abnormal BMD. Conclusion: Body weight control should include proper diet and exercise in accordance with each woman's BMI level.

Results of an experiment on the behavior of rats and mice in order to explore the possible pharmacological actions of Panax ginseng upon the central nervous system can be summarized as follows: 1. Spontaneous motor activity. In the case of mice, those groups who were administered 2.5 mg and 5.0mg of ginseng saponin per kilogram of body weight were observed to have increased their activity compared with the control group, while the 50.0 mg and 100.0 mg per kilogram body weight groups demonstrated lower levels of activity, with the peak of activity appearing at 30 minutes after administration of drugs. In the case of rats, those groups of animals who were given injections in the dosage of 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight demonstrated higher activity than the control group, while the 100.0 mg per kilogram group appeared to have decreased in their activity, with the peak action appearing 30 minutes after the administration of ginseng saponin. The 50.0 mg per kilogram group demonstrated no significant differential. 2. General behavior analysis. In the case of mice, decrease in sleeping component of behavior and increase in the walking and roaring components, compared those with the control group, turned out to be a common phenomenon among the groups who were administered 2.5 mg, 5.0 mg and 50.0 mg of ginseng saponin per kilogram body weight, with the 5.0 mg per kilogram group standing out of all the other groups in terms of their reactions. In the case of rats, ginseng saponin appeared to reduce sleeping component with 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight groups, while increased the walking and rearing components. It was observed that administratoin of ginseng saponin in a dose of 2.5 mg per kilogram appeared to markedly increase the lying and grooming components of animal behavior. 3. Open-field exploratory behavior. Adminstration of ginseng saponin to mice in doses of 5.0 mg, 50.0 mg and 100.0 mg per kilogram body weight decreased activity, but increased their exploratory behavior. In the case of rats, however, administration of ginseng saponin in the doses of 2.5 mg and 5.0 mg per kilogram body weight markedly increased their activities, while decreased activities with the 50.0 mg per kilogram and 100.0 mg per kilogram groups. The exploratory behavior of rats appeared to have decreased, while grooming increased ramarkably. 4. The above findings from a series of experiment appear to suggest a stimulating effect on the central nervous system when ginseng saponin is administered in small doses, but that larger doses might result in an inhibitory effect, though differential results can be anticipated with modification of experimental conditions.

Purpose: This study was done to identify the relationships between body mass index, nutritional knowledge and the health promotion behavior of nursing students. Methods: Participants consisted of the entire 330 members of the student body of a Korean nursing college. Variables included body mass index, nutritional knowledge and health promotion behavior as well as demographic variables. Data was analyzed by frequencies, ANOVA and Pearson's correlation with the SPSS/Win 21.0 program. Results: The mean score for body mass index was $20.23kg/m^2$ for nutritional knowledge, $14.27{\pm}3.07$ on a total 20-point scale, and for health promotion behavior, $3.03{\pm}0.34$ on a 4-point scale. Nutrition knowledge positively correlated with health promotion behavior (r=.368, p<.001). Health promotion behavior positively correlated with underweightness (r=.120, p=.005), normal weight (r=.212, p<.001), negatively correlated to overweightness (r=-.351, p<.001), and obesity (r=-.413, p<.001). Nutrition knowledge positively correlated to underweightness (r=.155, p=.005), and normal weight (r=.346, p<.001), negatively correlated to overweightness (r=-.548, p<.001), and obesity (r=-.342, p<.001). Conclusion: In order to enhance the effective health promotion behavior of nursing students, it is important to actively intervene to improve body weight control behavior and nutritional knowledge. Therefore, developing an educational program for improving nutritional knowledge and body weight control behavior of nursing students is recommended.

This study was performed to investigate the effectiveness of nutrition education and exercise intervention in a weight management program. The subjects were 24 obese women whose body mass index (BMI) was over $25kg/m^2$. Nutrition education was given once a week, and subjects did swimming three times a week. The program lasted for 12 weeks. Nutrient intakes were assessed by 24 hour recall method. Also food habits, dietary behavior and nutrition knowledge were examined by self-administered questionnaires before and after the weight control program. Height, weight, body composition and blood composition were measured before and after the weight control program. Over the 12 weeks in the weight control program, body weight significantly decreased from 69.7kg to 65.8kg(p<0.001). Body fat and BMI also significantly decreased(p<0.001). Cholesterol level significantly decreased at p<0.001 and blood sugar also significantly decreased (p<0.05). After taking nutrition education, dietary behavior and nutritional knowledge scores increased, energy intakes decreased from 1426.5kcal to 1408.5kcal and calcium from animal products significantly increased(p<0.05). A negative correlation between nutrition knowledge and BMI(r=-0.42) existed(p<0.05). A negative correlation of eating behavior with EER(r=-0.48) showed(p<0.05). We concluded that combined nutrition education and exercise was an optimal method for reducing weight.

BACKGROUND/OBJECTIVES: This study aimed to examine differences in weight control practices, beliefs, self-efficacy, and eating behaviors of weight class athletes according to weight control level. SUBJECTS/METHODS: Subjects were weight class athletes from colleges in Gyeong-gi Province. Subjects (n = 182) responded to a questionnaire assessing study variables by self-report, and data on 151 athletes were used for statistical analysis. Subjects were categorized into High vs. Normal Weight Loss (HWL, NWL) groups depending on weight control level. Data were analyzed using t-test, ANCOVA, x²-test, and multiple logistic regressions. RESULTS: Seventy-three percent of subjects were in the HWL group. The two groups showed significant differences in weight control practices such as frequency (P < 0.01), duration and magnitude of weight loss, methods, and satisfaction with weight control (P < 0.001). Multiple logistic regression showed that self-efficacy (OR: 0.846, 95% CI: 0.730, 0.980), eating behaviors during training period (OR: 1.285, 95% CI: 1.112, 1.485), and eating behaviors during the weight control period (OR: 0.731, 95% CI: 0.620, 0.863) were associated with weight control level. Compared to NWL athletes, HWL athletes agreed more strongly on the disadvantages of rapid weight loss (P < 0.05 - P < 0.01), perceived less confidence in controlling overeating after matches (P < 0.001), and making weight within their weight class (P < 0.05). HWL athletes showed more inappropriate eating behaviors than NWL athletes, especially during the weight control period (P < 0.05 - P < 0.001). CONCLUSIONS: Self-efficacy was lower and eating behaviors during pre-competition period were more inadequate in HWL athletes. Education programs should include strategies to help athletes apply appropriate methods for weight control, increase self-efficacy, and adopt desirable eating behaviors.
