The purpose of this study is to collect fundamental data for weight control education based on obesity, weight control practices and body image in female college students. Those surveyed were 364 female college students attending universities in Seoul, Kyoung-Gi and Chung Cheung Buk Do. The data were collected from June 1, 1999 to September 10, 1999. The resulting data are as follows: 1. The mean BMI of the female college students was 19.78:t1.87kg/$\textrm{m}^2$, which comes within the range of normal weight. Underweight, normal weight and overweight students were respectively 27.2%, 66.8% and 5.5%. As many as 7.1% of the underweight students and 42.8% of the normal weight students described themselves as being "fatty". 2. Of these subjects, 83.5% reported wanting to lose weight, and the primary reason of weight control was to improve their appearance. The mean weight that they wanted to lose was 5.2$\pm$2.7kg, and 68.7% of the respondents had tried to lose weight. Among them, the most frequently reported weight control behavior was dieting followed by exercise, 30% reported fasting, 3.6% reported using drugs, 4.4% reported smoking and 3.6% reported vomiting. As to the weight loss effect, 96.7% of the subjects used behavior modification, 82.5% of the students exercised, and 76.1% of the dieters reported they had lost weight. 3. As to body image, many female college students were dissatisfied with their body figures, especially thighs(70.3%), hips(60.4%), abdomens(60.2%), and weight(55.2%). The body image of the students that perceived themselves as "fatty" was the lowest. 4. There were significant differences in the mean weight that they wanted to lose and the weight control attempts according to weight perception. Those that perceived themselves as "fatty" wanted to lose more weight, and had more weight control experiences. In conclusion, attempts at weight control are common in the female college students and many students appear to be dissatisfied with their body shapes. It is important to educate about healthy weight control methods and raise their awareness of the positive body image.ss of the positive body image.

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.

The purpose of this study were 1) to identify the effects of age and sex of Korean adolescents on the psychological variables(body attitudes, public/private self-consciousness, self-esteem), weight control practices, and clothing behaviors, and 2) to identify the relation- ships between psychological variables and weight control practices, and the effects of the variables on clothing behaviors in the adolescent' groups classified by sex and age. The results of this study were as follows: 1) Two factors of body attitudes were identified: Body-shape consciousness and Physical attractiveness. Four factors of clothing attitudes were identified: Clothing interest/dressing for others, Clothing exhibition, Dressing for self, and Psychological clothing-dependerlce. 2) There were significant effects of sex on all of the research variables. Age was found to have effects on Physical attractiveness, self-esteem, public/private self-consciousness, Clothing exhibition, and Psychological clothing- dependence. 3) In the relationships between psychological variables and weight control practices, Body-shape consciousness was negatively correlated with Physical attractiveness in all groups. Also, Body-shape consciousness had effects on weight control practice in all subject groups. 4) Public self-consciousness had direct/indirect effects on the Clothing interest/dressing for others in all subject groups. Private self-consciousness had direct/ indirect effects on dressing for self in high school boys and girls. Body-shape consciousness had indirect effects on Preference for up-to date style in male college students group, whereas weight control practices had effects on the Preference for up-to date style in female college students group. Self-esteem was found to have the effects on clothing behavior in college students groups. Among clothing attitude factors, Clothing exhibition had distinct effects on the Preference for up-to date style in all subject groups, and Clothing interest/dressing for others had effects on Clothing exhibition and Psychological clothing-dependence in high school boys and girs.

Objectives: This study was to investigate how body-shape perception could influence to weight control practice both in normal and obese group. Methods: We used 2012 Korea National Health and Nutrition Examination Survey to analysis 1) weight control practices of population; 2) consistency between body-shape perception and body mass index; 3) comparison weight control practices between normal group and body mass index (BMI) obese group in perceptional obese group; 4) odds ratio of BMI obese group using herbal drugs for weight control practice in perceptional obese group. Results: We found that study population tends to choose exercise, dietary restriction, meal skip, health functional food, one-food, drug, herbal drug, fasting and self-medication in order of frequency to control weight. The agreement between body-shape perception and BMI within obese group was approximately 64% with 0.40 of Cohen's Kappa coefficient, ranging from 0.384 to 0.423. Within perceptional obese group, choosing each weight control practice methods ratios between normal BMI group and obese BMI group were not significantly different. Within perceptional obese group, obese BMI group showed significant odds ratio (2.58, 95% confidence intervals, 1.38~4.85) than normal BMI group in choosing herbal medication for weight loss when adjusting other variables. Conclusions: We concluded that body-shape perception might be an important factor for choosing weight control program, and roles of Korean medical doctors thought to be enhanced for using herbal medication for weight loss.

This study was conducted to investigate the relationship between body image and BMI with satisfaction of own body image, snack intake practices, food intake practices and weight control practices of 226 female college students in Jeonbuk province using questionnaire. The results were summarized as follows : 1. The average height, weight and BMI was 162.08cm, 52.02kg and 19.78, respectively. The average ideal body weight of the subjects was 48.92kg. Ninety percent of the subjects was dissatisfied with their body image. The degree of dissatisfaction was higher in the group who recognized themselves as fat. Most of subjects wanted to lose weight, but as the group having a recognition of thin body image significantly wanted to gain weight (p<0.001). 2. The subjects preferred fruits and juices for snack. The more subjects recognized themselves as fat, the more they restricted snack intake (p<0.05). 3. The rate of skipping meal tends to increase. The subjects did not intake balanced meals and skipped breakfast most (20.7%). The number of food groups taken at breakfast, lunch and dinner was 1.84, 2.25 and 2.55, respectively and the most variable food groups were taken at dinner(p<0.001). Dairy food group intake was low. The duration of meal time was longer in the underweight group by BMI regardless of body image recognition (p<0.05). 4. The weight controlling method was concentrated mostly on decreasing food intake. The more subjects recognized themselves as fat, the more they tried to control weight (p<0.001). Even though 59.5% of the subjects with no weight control experience had no future weight control plans, 50% of the group who recognized themselves as normal or fat did not want to control weight in the future (p<0.01). These results suggest that nutrition education programs and correction programs of food behaviors and weight control should start from focusing on the accurate recognition of body image for college female students.

The purpose of this study was to identify the adolescent girl's weight control practices, degree of obesity and body image. The data were collected from July 1st to 15th, 1996 using the questionnaire and the physical examination record. The subjects of this study were 295 junior high school girls. Darta were analyzed with percentages, means, t-test, ANOVA, Kruscal-Wallis one way ANOVA, Scheffe test and pearson correlation coefficients using the SPSS program. The results were as follows: 1. The mean for the degree of obesity in subjects was -1.26%. The 34.2% of the subjects were underweight, the 46.8% were normal, the 9.2% were overweight and the 9.8% were obese. The girls who perceived themselves obese were 39% and only the 47% of them were really over-weight and obese. 2. The mean score of body image was 139.30. It was 145.51 for underweight girls, 128.07 for normal weight girls and 125.17 for obese girls. The higher the degree of obesity was, the lower body image score was. The body image score of the girls who perceived themselves obese was significantly lower than that of the girls who perceived themselves normal or underweight. 3. The 65.1% of subjects experienced weight control practices. They reported that they had used the following weight control methods such as diet(42.2%), exercise(35.9%), diet and exercise(15.1%) and others including drug(6.8%). The degree of obesity was significantly higher and the body image score was significantly lower in the case of the girls who had weight control experiences than in the case of those who had no weight control experiences. 4. The 60% Of the subjects often had 2 meals per day. The 48.8% of the subjects tended to skip breakfast, the 7.8% would skip lunch and the 20% did not have dinner. The higher the degree of obesity was and the lower body image score was, the more the girls would skip their meals. In conclusion, many adolescent girls tended to believe their body weight heavier than their real body weight. Many girls who were not overweight and obese tried to lose weight. In the case of the girls whose degree of obesity was high or who perceived themselves obese, the body image score tended to get lower and the weight control practices tended to be increased.

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 aimed to assess the prevalence of weight control behaviors and their association with food and nutrient intake among Korean adults. Study subjects were 7,340 Koreans aged 20 years and older in the 1998 Korean Health and Nutrient Survey. Cross-sectional data were collected on weight control behavior and diet using structured questionnaire by interview. Analysis of variance following after Duncan's multiple range test was used to test the differences in food and nutrient intake among three different weight control behavior groups(weight reducing attempt, weight gaining attempt, none). Current weight control behaviors were reported by 32% of the study subjects. There were significant differences in weight control behaviors between male and female subjects; weight reducing practices were 7 times greater than weight gaining practices among female subjects while it was only 1.5 times among male subjects. Weight control behaviors were not consistently associated with food and nutrient intake among male and female subjects. Moreover, greater food and nutrient intake were observed among those who trying to reducing weight than those who did not try. Therefore, it Is necessary to educate the Korean adults that balanced food and nutrient intake with sustaind weight control effort is the ideal way to achieve healthy weight.

Objectives: This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both χ2 and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weight-control. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weight-control foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning 'slightly satisfied' and 'slightly dissatisfied', respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.

This study investigated the association between the weight status of middle school students and the various weight-related characteristics including desired weight, weight perception, weight-related practice, physical activity, and overeating behavior. Questionnaires were administered to 473 middle school students (178 boys and 295 girls) in Daejeon. Boys and girls were divided into three groups respectively; (1) underweight (BMI<$5^{th}$ percentile) (2) normal weight ($5^{th}$ percentile$\leq$BMI<$85^{th}$ percentile) (3) overweight (BMI$\leq85^{th}$ percentile). Using BMI calculated from measured height and weight, 14.0% of boys and 6.8% of girls were underweight, and 16.3% of boys and 14.2% of girls were overweight. However, among this sample of students, 38.4% of boys and 13.6% of girls perceived themselves as underweight and 29.4% of boys and 44.9% of girls perceived themselves as overweight. We found that overweight students reported their body weights lower and their heights higher compared to non-overweight students, resulting in an underestimation of BMI. Based on desired BMI, 79.9% of the girls desired to be underweight and 73.0% of the boys desired to be normal weight. Overweight or normal weight students were less satisfied with their body weights than underweight students. Girls had more weight control experience and concern compared to boys. Overweight girls spent longer times in watching TV compared to non-overweight girls (p < 0.001) and had more overeating behaviors (p < 0.05). Overweight students reported that they ate snacks less frequently than non-overweight students, which may be due to their tendency to report less eating. In conclusion, significant gender differences and weight status differences existed in weight perception, weight satisfaction, and weight control experience and concern. Because perception of overweight is likely to lead to unhealthy eating behaviors and weight control, efforts for adolescents to improve accuracy of weight perceptions and to understand the benefits of being healthier are needed.
