This study was conducted to investigate the effects of a weight control programs on BMI, nutrition knowledge, physical fitness and stress level of adult obese women. The subjects of this study were 36 adult obese women aged 30-65 years whose BMI were above $23\;kg/m^2$. The weight control program for obese women included nutritional education, exercise and cognitive behavioral therapy for 12 weeks. The BMI of the subjects was significantly decreased (p < 0.001) from $27.1\;kg/m^2$ to $26.4\;kg/m^2$ after the 12 weeks of the weight control program. In addition, the weight of body fat was significantly decreased (p < 0.001) and % body fat was significantly decreased (p < 0.05) from 35.4% to 34.9% after completion of the weight control program. In addition, nutritional knowledge (p < 0.001) and eating behavior scores (p < 0.01) were significantly increased. However, the food intake scores were not changed after the program. Stress levels of the adult obese women were significantly decreased (p < 0.001) from 85.63 to 66.88 and also obesity stress levels were significantly decreased (p < 0.01) after the weight control program. In the physical fitness levels of the subjects, muscle endurance (p < 0.05) and ability of balance (p < 0.01) were significantly improved after completion of the weight control program. There were positive significant correlations between general stress and obesity stress level (p < 0.05), and negative correlations between stress level and food intake score (p < 0.05). These results showed that the weight control program for adult obese women may be effectively used to improve weight reduction, physical fitness and stress levels.

This study was conducted to identify the factors associated with weight control and nutritional knowledge of juvenile delinquents. The average heights of the subjects in this study were 172.20 cm (male) and 160.89 cm (female), and the average weights were 66.73 kg (male) and 58.42 kg (female), and the BMIs (Body Mass Index; $kg/m^2$) were 22.46 (male) and 22.54 (female). The results of this study revealed that 41.4% of the subjects were over weight or obese. In addition, there were significant differences in the BMI, satisfaction with body image and perception of body image observed between male and female subjects. Furthermore, female subjects were more experienced at weight control than male students (p<0.001). Additionally, overweight and obese individuals had more experience with weight control than subjects that were not overweight. Moreover, there were significant differences in the reason that subjects took weight control measured between male and female students. Specifically, female subjects practiced weight control due to their appearance (p<0.001). The order of methods by which male subjects attempted to control their weight was exercise>diet control>starvation and for girl student were diet control>starvation>excercise. The nutritional knowledge scores were higher for female subjects than for mele subjects. In addition, the nutritional knowledge scores increased as the BMI value increased and the $father^{\circ}{\emptyset}s$ educational level increased. These results of this study could be useful data to plan and develop nutritional education programs for juvenile delinquents.

This study was conducted to investigate the weight concerns of female university students living in Jeonju, as well as their control on behavior. Self-administered questionnaires were collected from 285 students. Statistical data analysis was completed using the SPSS v. 11.0 program. The results are summarized as follows: The average weight, height, and BMI of the subjects were 21.43 kg, 161.93 cm, and 19.8, respectively. With regard to body image, most were dissatisfied with their figures, especially the hips and thighs. About 42% of the students estimated their figures as 'slightly fat', while 5.4% stated 'very fat', even though their BMI classified as 'normal'. Four percent of the underweight students described themselves as being 'fatty'. Approximately 93% of the students had strongly pursued weight control, and 45.3% reported wanting to lose about $2{\sim}5$ kg. Almost 73% of the respondents had weight loss experience. The primary reason for weight control was to improve self-confidence. Only 19.6% had succeeded in losing weight, while nearly 48% had stopped dieting. To reduce weight, about two thirds of the students ate less(e.g. no snacks, no sweets). Fifty percent tried to reduce weight by more physical activity(e.g. sports). Television(50.9%), friends(48.4%), and newspapers/magazines(40.4%) were essential sources of pertinent information. In conclusion, the results show that female students in Jeonju have a great interest in weight reduction. Thus, the majority are willing to try several methods for weight reduction, which however, are not promising and not based on a lasting nutritional change. Therefore, it's necessary to increase cooperation among those concerned(e.g. dietitians, teachers, parents, media) and to develop weight-control programs that take into consideration lifestyle and daily habits, as well as combine physical activity, nutrition, and behavioral and personality training.

This study purposed to examine the participative intention for health promotion program in a university and to find out the factors to associate with the participative intention. The data were based on the self-reported questionnaires from 746 women who study in E university, and this survey performed May, 1998. This study performed to analyze the participative intention for health promotion programs and the factors associate with health promotion program using $chi^2$-test and trend test by the PC-SAS 6.12. The major findings were as follows: 1. The tendency of participative intention for health promotion programs showed that Influenza preventive program was the highest among the health promotion programs, and the next were Weight control program, Rubella preventive program, Fitness program. On the other hand, Smoking preventive program and Non-drinking program were lower than the other program. 2. The four significant factors on participative intention for health promotion programs were grade, concern for health, and behavior change experience through the health education. On the other hand, the cognitive level for health, experience for health education were not the significant factors associate with the participative intention for health promotion programs. 3. The relationship between factors and each health promotion program showed that Rubella preventive program, Influenza preventive program, Weight control program, Smoking cessation program and Non-drinking program were associated with the grade or the health concern. And Chronic diseases preventive program was associated with the grade and the concern for health. Fitness program and Sex education program were associated with the concern for health and the behavior change experience through health education.

This study was designed to investigate body image, objective and subjective measurements of body size and shape, eating behavior, and weight control practices in 650 Korean adolescent girls; 500 of the subjects were 14 years old and enrolled in middle schools, while the remaining 150 were 17 years old and enrolled in high schools. Subjects responded anonymously to a self-administered questionnaire. The results showed that average height and weight of the subjects were 157cm and 49.5kg, respectively, while subjects ideal heights and weights averaged 164cm and 48kg, respectively. The ideal adult body heights and weights proposed by the subjects averaged 172cm and 55kg respectively. Over 50% of the subjects were dissatisfied with their body image; the degree of dissatisfaction with body image was higher in those who believed themselves to be fat. Most of the subjects wanted to lose weight and had tried to lose weight. Self-reported weight control practice methods included reducing food intake (31.9%), skipping meals (29.6%), exercise (25.8%), using slimming machines (6.9%), and using diet pills (5.1%). The heavier the subjects weight was, the greater the difference between the subjective and objective evaluations of body size. The body image scores of subjects who perceived themselves as fat were significantly lower than those of subjects who perceived themselves as normal or underweight. The difference between subjective and objective evaluations of body size, and the degree of obesity, were significantly higher in those subjects who had experience of weight control than those who had no experience of weight control. These results suggest that nutrition and health education programs for adolescent girls should be researched and implemented in order to establish a more realistic body image, positive habits in weight control, and healthful eating habits.

This study was conducted to investigate the body weight control, attitudes, lifestyles and dietary habits according to the obesity index of elementary school students. This study utilized questionnaires and body composition measurements collected with a bio- electrical impedance analyzer(Inbody 4.0). Specifically, differences between the underweight group, normal group, and overweight group were tested by a $x^2$-test or ANOVA and Duncan's multiple range test. The subjects consisted of 571 elementary school students residing in Chonbuk Province. The average age, height, weight, and BMI of the male subjects was 11.5 years, 150.0 cm, 45.2 kg and $20.0\;kg/m^2$, respectively. The average age, height, weight, and BMI of the female subjects was 11.5 years, 152.2 cm, 46.1 kg and $19.8\;kg/m^2$, respectively. Twenty percent of the subjects were in the underweight group, 52.2% were in the normal weight group, and 27.8% were in the overweight group according to the Korean Pediatrics Society standards. A total of 50.2% of the subjects were dissatisfied with their body weight, while 36.8% of underweight, 42.3% of normal weight, and 81.1% of overweight subjects were dissatisfied with their weight. Fifty two percent of the subjects had attempted to reduce their body weight, including 50% of the normal weight group. The main reason for wanting to reduce body weight was to maintain health. The percentage of subjects who had received body weight control education was 41.3%, but 77.6% of the subjects thought it was necessary. Poor time management, lack of physical activity, portion size of meals, unbalanced diet, frequent consumption of convenience foods, and frequent snacking all affected the obesity index. Overall, the results of this study indicate that it is necessary to develop weight control programs for all elementary school students who are underweight, normal weight, and overweight.

This study was conducted to investigate the eating habits, self-perception of body image, and weight control behavior in Korean adolescents by gender. Data pertaining to 70,809 subjects(male 37,090, female 33,719) were obtained from the sixth Korea Youth Risk Behavior Web-based Survey(2010). The rate of skipping breakfast was 42.5% in male, and 45.8% in female students. The intake frequency of vegetable, milk, soda, fast food, and instant noddles was higher in male than female students. Moreover, 33% of male and 31.9% of female students considered themselves to be somewhat or very obese. Notably, 2.3% of underweight students considered themselves to be obese. Weight control measures were practiced in 44.6% of male, and 54.6% of female students. Meal restrictions were used more frequently to control weight by females, while exercise was used more by males. The perceived stress level was higher in female than male students, especially that due to appearance. Therefore, integrated and personalized high school nutrition programs according to gender should be implemented to establish proper body image perception and eating habits, as well as to develop selfesteem.

This study was conducted to investigate the change in the anthropometric values, biochemical index, nutritional knowledge, food habits and nutrient intakes in obese children after a weight control program. The subjects of the study were 22 obese children with an obesity index over 120%. The children that participated in this study took nutritional education for weight control along with exercise once a week. The weight control program was conducted for 10 weeks. The BMI, WHR (Waist-Hip ratio), body fat (%) significantly decreased at the end of the weight control program. Total cholesterol and LDL cholesterol were also significantly decreased. The nutritional knowledge scores and knowledge score about obesity were slightly improved. Energy intake significantly decreased from 1768 to 1421 kcal. Intake of Ca, Na, K, vitamin A, vitamin $B_6$, vitamin C and folate increased, while intakes of P, Zn, vitamin $B_1$, vitamin $B_2$, vitamin E and niacin decreased. The distribution of energy intake was significantly changed for the better. The percent fat consumed decreased from 26.5 to 19.7%. In addition, the distribution of energy intake in the meals was changed, where the percent calories consumed during lunch significantly increased from 31.4 to 40.1% and the calorie percentage consumed from snacks significantly decreased from 17.6 to 10.7%. In conclusion, the nutritional education in the weight control program, which was conducted for 10 weeks, was effective in improving the anthropometric values, biochemical index and nutrient intake although nutrition knowledge and eating behaviors only changed slightly. Thus, nutritional weight control programs for obese children should be continuously provided under the proper cooperation of a nutritional teacher at elementary schools.

Concern about body weight among adolescents is too much, so distorted body images and weight control are serious problems among Korean girl students. This study was carried out to investigate perception of body images, weight control, food habits and eating behavior of 237 high school girl students in Seoul and Incheon. The subjects were divided into four groups based on Body Mass Index (BMI)-under weight ($21.3\%$), normal ($62.6\%$), over weight ($8.1\%$) and obesity ($8.1\%$). The survey was conducted from June to July 2005. The mean weight, length and BMI of the subjects was $53.4\pm7.4\;g,\;101\pm4.8\;cm,\;and\;20.6\pm2.7$, respectively. $56\%$ of the under weight group and $40.8\%$ of normal group had incorrect perception about their body images and $28.5\%$ of the under weight group and $76.9\%$ of the normal group had dissatisfaction about their body images. Most of the students were concerned about their body images and weight control. Dietary habit scores showed significant differences among the groups. These results suggested that effective nutritional programs should be developed including correct Perception of body image and good dietary habits.

Purpose: This study aims to analyze the outcome of exercise programs for Rheumatoid Arthritis patients and its tendency with network analysis. Method: 30 articles from Medline search of foreign nursing journals(1966-2002) and 5 from three Korean nursing journals(1970-2002) were surveyed. The contents analyses were focused on outcome measures and network analysis of exercise programs. Results: Exercise programs result in improving muscle strength(91.7%), aerobic capacity(72.9%), and 50 feet walk time(57.3%). Among several exercises, water exercise, and Tai-chi are in the middle of weight-bearing exercises. In the experimental design, non-randomized control trials were 40%, and the functional status of subjects were not classified in 40% of the articles surveyed. Conclusion: Considering the results, muscle strength, aerobic capacity, and 50 feet walk time were tested as valid outcome measures. Tai-chi exercise could be recommended as proper exercise for Rheumatoid arthritis patients because of its low intensity of weight-bearing exercise. In terms of research methods, the randomized trials and functional classifications of rheumatoid arthritis should be done more strictly.
