The study purpose was to examine weight control status and related factors among 370 high school girls in Seoul. Factors examined included interest toward weight control, body satisfaction, body image, beliefs regarding weight control and self-efficacy. $65.1\%$ had attempted to control weight and were categorized into attempt group. Those in the attempt group had higher body weight (p < 0.001) and BMI (p < 0.001) than the counterparts. They tried to control weight 2.9 times on average (22.4 days each time). The major information sources for weight control were internet ($62.8\%$), and TV/radio ($17.1\%$). Exercise was most commonly used for weight control, followed by reducing meal amount and skipping dinner. The attempt group was less satisfied with body size (p < 0.001) and perceived their body size as heavier than the counterparts (p < 0.001), but they showed more interest toward weight control (p < 0.001). The ideal body size of society or the body size that they want was very thin in both groups. Twelve out of 20 beliefs regarding weight control were significantly different between the two groups. The attempt group believed more strongly on the advantages such as increased self-confidence, appearance, attractiveness (p < 0.001) and 'good for making friends' (p < 0.01) In contrast, the attempt group believed less strongly about the disadvantages including harmful effects on health (p < 0.001), parents' dislike, feelings of discouragement (p < 0.01) and becoming (p < 0.05). The attempt group showed lower overall self-efficacy to control overeating (p < 0.05) than the counterparts. Especially, the attempt group felt less control of overeating in situations such as eating-out, after school, when they are with family (p < 0.01) or with friends, when they feel hungry, during examination periods and when others offer food (p < 0.05). This study suggested that weight management education for adolescents include strategies for changing body image and beliefs regarding weight control, as well as increasing self-efficacy to control overeating.

It is frequently observed that consumers' behavior and performance in their weight control are greatly affected by the degree of self-control by the consumers themselves. In other words, effective weight control behavior is only possible when the consumers invest a substantial amount of endeavors and self-control. The present study empirically investigated the effect of the self-image congruence and subjective norm formed by self- concept reflected in weight control behavior on weight control attitude formation, actual behavior, and performance. For more in-depth research, rather than simply showing differences in performance based on self-control, the present study divided the subjects into high and low self-control groups for a comparative purpose. Based on empirical research employing general consumers and those who were engaged in an actual weight loss program at professional weight control centers as subjects, the study found the following results: First, for both high and low self-control groups, self-image congruence significantly affected attitude toward weight control, but not the actual weight control behavior. The results indicate that in weight control, the actual behavior must be preceded by the attitude. Second, subjective norm directly affected both attitude toward weight control, and behavior for the low self-control group while it affected the behavior only for the high self-control group. The results show that the lower self-control is, the more powerful the effect of referents is. Third, weight control attitude positively affected weight control behavior only for the high self-control group. Fourth, weight control behavior significantly affected the performance for both high and low self-control groups. Compared to the low group, the high self-control group showed more powerful effect of behavior, suggesting the crucial role of self-control in successful weight control. The results also imply that the role of referents is relatively more important for the low self-control group.

This study was undertaken to explain weight control behavior and intention of obese children and adolescents as measured by the elements of the health belief model. A total of 732 obese students from 28 schools in Seoul metropolitan area and their mothers were assessed with a self-administered questionnaire. The analyzed results are as follows; 1. Among obese students, 45.3% of male students and 57.2% of female students, a significantly higher portion than male students, reported that they had tried to lose weight within the recent year. Exercise was the most frequently used method to lose weight followed by diet control, drug use, and specialized clinic visits, in descending order. 2. Male students were more likely to try to lose weight if they perceived a low threat level and their mother had a job, and female students were more likely to try to lose weight if they were younger in age, perceived a low threat level and had strong external motivating factors. 3. Female students showed a significantly higher level of intention to obesity control than male students, and the intention level of their mothers also showed the same trend. 4. In male students, the degree of weight dissatisfaction, weight control experience, the level of obesity related beliefs of students, the educational level of the mother and economic status of the family were significant predictors of intention to obesity control, and in females, age, the level of obesity related beliefs of students and intention of their mothers were significant. In the mothers of male students, obesity index of students, age of the mother and the level of obesity related beliefs of the mother were significant predictors of intention of the mother, and in the mothers of female students, obesity index of students, occupational status of the mother and obesity related beliefs of the mother were significant. 5. According to the path model of intention to obesity control, the degree of weight dissatisfaction had the most powerful effect in male students, and perceived net benefit level was the most important variable in female students. Since the weight control behavior and intention of obese students were more predictable by the degree of weight dissatisfaction than the obesity index, we can conclude that only the students dissatisfied with their weight are well motivated for obesity control. There can be a discrepancy between the mother and her child's beliefs and intention status(especially in male students), so the therapists should also assess the student's opinion as well as the mother's. In female students, the perceived net benefit level wag the most important predictor of intention to obesity control, therefore the intervention program should pay particular attention to the positive benefits of weight control rather than negative aspects(threats) of obesity.

The purpose of this study was to investigate the effects of body weight control program for obese children. The program included nutrition education, exercise and behavioral therapy for 20 weekly sessions. The results from this study were as follows. The average age of the subjects was 11.3 years, mean height and weight were 146.12cm and 59.42kg respectively. After weight control preogram, Rohrer index(Rl) was significantly decreased from 186.78 to 182.72(p<0.001). There were not significant differences in body fat percent(%) and fat weight(kg) but it showed decreased pattern. In the change of body circumferences, chest circumference was significantly increased(p<0.01) and mid-arm circumference was significantly decreased(p<0.001) after weight control program. Triglyceride(TG) level in serum was significantly decreased from 113.79 to 80.36(p<0.01) and total cholesterol and LDL-cholesterol level showed declind pattern. The food habits of obese children significantly improved(p<0.001) after weight control prgram. And there were desirable changes of food attitude, excercise and life habits. These results suggest that weight control program including nutrition education, exercise and behavioral therapy may be effective for helping obese children.

The purpose of this study was to evaluate the body composition, health status, and dietary behaviors of middle-aged women in a weight control program at a community health center. The study subjects were 66 middle-aged women who lived in Ansan city, and they participated in the program for 24 weeks. Anthropometries, blood pressure, and serum biochemical indices were measured. These measurements were taken both before and after the weight control program, and the data were analyzed using the SPSS 12.0 program. Weight, fat mass, body fat %, and the waist-hip ratio all decreased. According to the decreases in body fat %, blood pressure, serum biochemical indices and dietary behaviors were improved after the weight control program. Thus, this study demonstrated the desirable changes of a weight control program offered at a community health center, for health conditions and physical fitness.

This study examines the relationships between dietary self-efficacy, social support, depression, and weight-control behavior of children and adolescents. A total of 593 students (280 children and 313 adolescents) from schools in Seoul, Gyeonggi-do, Jeollabuk-do, and Daegu were surveyed using scales for dietary self-efficacy, social support, depression, and weight-control behavior. The data were analyzed through a frequency analysis, means and standard deviations, a t-test, a one-way ANOVA, the Tukey test, the Pearson's correlation, and a stepwise multiple regression analysis. According to the results, weight-control behavior was more likely in girls than boys, high-school students than elementary-school students, and obese/overweight students than normal/underweight students. The factors influencing children's weight-control behavior were general eating habits, the BMI, depression, food choice, and family support, in that order, and those influencing adolescents' weight-control behavior were general eating habits, gender, and the BMI, in that order. These results are expected to be useful as basic data for developing weight-control programs for children and adolescents.

This study was conducted to investigate the effects of weight control program on nutrient intakes and physical fitness of Korean obese adult women. The subjects of this study were 33 obese adult women aged 30-65 years residing in Seoul. The weight control program for obese women included nutrition education, cognitive behavioral therapy and exercise for 12 weeks. There were significant decrease (p < 0.001) of blood pressure and atherogenic index of obese women after the weight control program. Energy intake was significantly decreased (p < 0.001) from 1556.9kcal to 1044.9kcal after 12 weeks of the weight control program. Also protein, fat and carbohydrate intakes were significantly decreased. The ratio of energy intakes per day for the subjects was carbohydrate 64% : protein 16% : fat 20%. The frequency of vegetables intakes was significantly increased (p < 0.05) and there were no significant differences in other food groups. After the weight control program, muscle endurance, flexibility, balance and explosive muscular strength of subject's physical fitness were significantly improved. These results suggest that the weight control program for obese women may contribute to nutrient intakes reduction and improvement of physical fitness.

The purpose of study was to test the hypothesis that three are differences in body size dietary behavior and nutrient intakes of adolescent girls with weight control experience. Cross-sectional survey was carried out with a questionnaire and anthropometric measurements . Subjects were 724 healthy adolescent girls from middle and high schools of urban and rural areas in Inchon and divided into two subgroups with weight control experience. Subjects trying to lose weigh were 25.1% in middle school girls and 47.1% in high school girls. There were significant differences in weight and BMI between weight control experience and non- experienced groups in middle school students. There were significant differences in skipping meals and reason of skipping meals between weigh control experience and non-experience groups which might show that skipping meal was used as a weight loss method among female school students. There was no significant difference in nutrient intakes between weight control experienced and non-experienced groups in middle and high school subjects. these results suggest that nutrition education is necessary for adolescent girls to practice appropriate weigh control strategies including desirable eating habits and adequate intake of nutrients such as energy vitamin A vitamin B$_2$calcium and iron.

Purpose: This study was conducted to identify factors influencing the weight control behavior of female college students. Method: The subjects included female college students in the U City area, and data were collected through a self reported structured questionnaire from July 01 to 28 of 2017. Totally 220 subjects were analyzed. Analyses consisted of descriptive statistics, ANOVA, Pearson's correlation analysis, and stepwise multiple regression analysis. Results: The findings showed dissatisfaction of female college students' perceptions of their bodies based on BMI, body satisfaction and obesity stress, which had special impacts on their weight control behaviors. Weight control behaviors was closely influenced by obesity stress (${\beta}=.848$, p<.001) accounted for 48.7% of the weight control behaviors (F=71.97, p<.001). Conclusion: These findings indicate that it is necessary to develop and implement information programs and design appropriate prevention programs that can induce healthy weight control behaviors. Such programs should include health education, as well as intervention programs to identify such predictors and help college students judge and perceive positive body image so that they control their weight in a proper manner.

Purpose: The purpose of this study was to investigate the relationship between obesity, body image perception, and weight control for obesity management in adult women. Methods: The subjects of this study were 3,617 women aged over 19 years, who participated in the Seventh Korea National Health and Nutrition Examination Survey 2016. Data were analyzed through complex sampling design data analysis. Results: Right body image perception according to obesity was apparent between 70.6-81.7% of women and 76.5% of women with abdominal obesity perceived that they were normal. Obese women performed more weight control than non-obese women. Women with only abdominal obesity performed less weight control than non-obese women, and 47.3% of them performed weight control. Women who perceived themselves as obese performed more weight control than women who perceived themselves as non-obese (odds ratio, 2.08; confidence interval, 1.69-2.57), but body mass index was not observed to be associated with weight control. Conclusions: Education on abdominal obesity should be provided to increase awareness about abdominal obesity and its effective management, especially in women with only abdominal obesity. In addition, interventions for right body type perception should be provided for proper weight control along with prevention and management of obesity.
