The purposes of this study were to investigate the relationships between appearance interest, appearance satisfaction, and life satisfaction of adolescent, to disclose the differences of these variables according to demographic characteristics, and to examine the determinants of life satisfaction. The subjects were 322 teenaged girls (167 middle school students and 155 high school students) living in Seoul. The variables of appearance interest were plastic surgery, weight control, clothing interest, and hairstyle interest. Life satisfaction included school life satisfaction and daily life satisfaction. Appearance satisfaction had negative relationships with plastic surgery interest and weight control interest, while appearance satisfaction had no relationships with clothing interest and hairstyle interest. School life satisfaction and daily life satisfaction had negative relationships with plastic surgery interest. The upper class adolescents had high level of clothing interest and life satisfaction, and lower class adolescents had high level of plastic surgery interest and had low appearance satisfaction as compared to other classes. The adolescent group with high school grade had high level of appearance satisfaction, and the group with low school grade had high level of weight control interest. The life satisfaction was influenced by appearance satisfaction the most, and the next in the order by school grade, residence area, and weight control interest. The explanatory power of the four variables was 30.8%. Social stratification and whether mothers had an occupation or not had an indirect effect on the life satisfaction.

The purpose of this study was to assess the relationship between the mother's interest in weight control and its association with the preschooler's obesity and weight related concerns. This was a cross-sectional study based on 470 parents' self-reports. To score interests in weight control, mothers rated each of 6 items on a five-point Likert scale ranging from disagree (1) to agree (5). The perceptions of mothers' weights and their children's weights, mothers' Body Mass Index (BMI), preschoolers' Weight-Length Index (WLI) (%), and weight-related concerns were determined. The mothers' BMI was significantly correlated with interest scores of weight control in mothers (r=0.632, p<0.001) while their children's obesity was weakly correlated with the mothers' interest scores (r=0.133, p=0.025). Mothers with a high interest of weight control reported higher percentages of family history of obesity than mothers with lower interests (63.2% vs. 36.8%, p<0.001). Two-thirds of the mothers (65.4%) were accurate in their perceptions about their weights. Similarly, 63.7% of mothers knew exactly their children's weight-statuses. Compared with mothers with low interest in weight controls, mothers with high interest in weight control had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions about their children's weights. More than two-thirds of mothers (85%) reported not worrying about their children's obesity in the future. Only 14.3% of the mothers were satisfied with their current weight statuses. Three-fourths of mothers preferred exercise as an effective weight-control method for their children, 20% preferred diet therapy and 5.5% preferred behavior modification. More girls were overweight / obese, than boys (overweight: 16.1% (girl) vs. 12.8% (boy), obese: 5.4% (girl) vs. 4.5% (boy)). About 40% of overweight girls' mothers had low interests in their weight controls with low correct-perceptions in their children's weights, which suggests possible elevated risk of obesity, especially in girls, in the future.

Thinness has become a symbol for beauty acceptance and competence for women in our society especially for young college women. Relatively little is known about characteristics of women who are dissatisfied with their shape or weight and who are interested in performing weight control program. Four hundred college women in Seoul and Kyunggi-Do area were surveyed from November to December 1992 to investigate the relationship between the concern about weight control and various aspects of food related behaviors. The purpose of this research was to investigate the relationship between the weight concerns of college women and their aspects of several eating behaviors. Self-developed questionnaire was used after validity test. The results were as follows: 1) The average height weight and BMI value of subjects were 160$\pm$4.5cm 51.02kg and 19.86$\pm$4.5 respectively. 2) The 49% of subjects were highly concerned about weight control(high interest group) and 39% were moderate concerned(moderate interest group). 3) The average BMI and weight change per year were significantly higher in the high interest group than other groups. 4) The score of nutrition knowledge was also higher in the high interest group, 5) There were no significant differences among groups in the meal frequencies. and amount of nutrients intake. 6) The signs of eating trouble were found in subjects 59.0% of subjects felt feareness about weight gain after consumption of large amount of food. 7) The ratio of CPF was 64:14:22 and nutrient adquacy ratio(NAR) of energy was 0.94 NAR of Fe was 0.84 the other NAR of nutrient over 1.0.

The purpose of this study was to evaluate the obesity and weight control prevalence according to the gender and weight control attempt among middle school students in Seoul and Gyeonggi-do, Korea. The mean age of subjects were 14.4 years old. The mean height, weight and BMI value of boy students were 164.0 cm, 53.0 kg, and $19.7kg/m^2$, respectively, and the mean height, weight and BMI value of girl students were 159.4 cm, 49.8kg, and $19.6kg/m^2$, respectively. Both weight and BMI value of the weight loss attempt groups were significantly heavier and higher than those of the other groups (p < 0.01). In the perception on the body image, the girls perceived themselves to be more fat compared to boys, and the weight loss attempt group perceived their body image to be more fat compared to the other groups (p < 0.001). As for the interest degree of weight control, the interest degree of girls was higher than that of boys (p < 0.01). According to weight control attempt, in the order of the weight loss attempt group, the weight gain attempt group and the no weight control attempt group, the interest degree was significantly higher (p < 0.001). In the frequency and hours of exercise, there was significant difference by gender (p < 0.001). According to weight control attempt, the weight gain attempt group exercised more frequently than the other attempt groups (p < 0.01).

In this study, the interest of female high school students's(N=500) for weight control, as well as nutrient intake status, were analyzed. The mean age, height, and weight of the subjects were, 19.3 years, 162.2 cm and 55.4 kg respectively. Mean BMI was $21.1 kg/m^2$. According to BMI, the percentage of underweight, normal weight, overweight, and obese were 18.5 %, 60.3%, 11.3%, and 11.3% respectively. By the BMI criteria, 60.3% of the subjects were normal weight while the rate of self-recognition was 41.5%. The degree of satisfaction regarding self-body image was only 17.1% and 60.9% showed an interest in weight control. The reason for weight reduction were appearance(65.1 %) and health(24.2%). The body areas where subjects wanted to lose weight included the thighs(32.9%) and whole body(29.3%). They believed the most effective weight control strategy was exercise(81.1 %) and the strategies they used were diet(59.1 %) and exercise(40.4%). Energy intake was 1,733.4 kcal which was 86.7% of the estimated energy requirements(EER). Calcium, vitamin $B_2$, and vitamin C intakes were less than EAR by 34.4%, 40.4%, and 59.6% respectively. The intake of dietary fiber was 5.1 g only 21.1 % of the adequate intake(AI). In summary, high school females interested in weight control have significantly less calcium intake than their peers. The correlations between interest in weight control and weight and BMI were significant(p<0.001). The results of this study suggest that to achieve optimal growth, improved diets that include calcium, vitamin $B_2$, and vitamin C are recommended. High school females interested in weight control should especially be targeted for education on calcium intake.

This study was conducted to investigate weight control status and associated factors among health-related major female college students. The subjects consisted of 41 nutrition and 78 physical exercise major female college students. Nutrient intakes, biochemical index, nutrition knowledge (recognition and accuracy), interest of weight control, body satisfaction, self-recognition of health condition, self-evaluated body weight were studied. About 73% of nutrition and 79% of physical exercise major female students were in the normal range of BMI ($18.5{\sim}23$) and 2% of nutrition and 1% of physical exercise major female students were underweight, 10% of nutrition and 6% of physical exercise major female students were obese. There were no significant differences in height and weight by major but %body fat and WHR in physical exercise majors were significantly lower than nutrition major students (respectively p<0.01, p<0.05). Overall, nutrition intakes of subjects were not shown to be appropriate, especially Ca/P of subjects was shown $0.54{\sim}0.64$, fat% out of energy of subjects was shown $24.7{\sim}29.0$ and Na intake was shown above 2000mg. Recognition and accuracy of nutrition were higher than those of physical exercise majors (p<0.001). There were no significant differences in self-recognition of health condition, self-evaluated body weight, satisfaction of body shape by major and weight control attempt. But interest of weight control of attempter was higher than that of no-attempter in nutrition (p<0.05) and physical exercise major students (p<0.01). Significantly negative correlation was found in satisfaction of body and BMI, body fat mass, %bodyfat, WHR. And significantly positive correlation was found in interest of weight control and BMI, %bodyfat, WHR. It was noticeable to see that interest of weight control was positively correlated to accuracy and accuracy was negatively correlated to blood cholesterol level. Therefore, proper nutrition education for female college students is needed in order to improve their weight control-related health.

The proposed variables are their body-related variables(body satisfaction, weight control experience, the degree of diet interest, and obesity) and self-esteem. The sample group used for the study consisted of 359 high school students(male=168, female=191). Measurement scales used for the study were those of body-related variables, self esteem and eating disorder behavior, and data analysis was performed using $X^2$, t-test, Pearson's correlation, regression analysis. The results are as follows. First, there is a significant difference between male and female high school students regarding their obesity perceived by themselves, body satisfaction, the degree of diet interest, weight control experience, and deit behavior. Second, In male students, diet behavior shows a positive correlation with the degree of diet interest, weight control experience, and body satisfaction, but shows a negative correlation with body satisfaction. In female students, diet behavior is positively correlated with the degree of diet interest, weight control experience, and obesity, but negatively correlated with body satisfaction and self-esteem. Third, in male students, the variables that showed a influence on diet behavior as an eating disorder are weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 51.7% with the highest mark on obesity. In female, the variables that showed a influence on diet behavior as an eating disorder are the degree of diet interest, weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 66.0%.

This study purports to understand the direct and indirect effects between eating disorder behavior of female adolescents and their body-related variables(concerning the degree of diet regime, weight control, body satisfaction, and obesity), self-esteem and internal control, by checking three sub-categorized behavior of eating disorders of diet behavior, bulimia behavior, and eating control behavior. The sample group used for the study consisted of 190 female high school students and 292 female university students; measurement devices used for the study were those of body-related variables, self esteem and internal control, and eating disorder behavior; and data analysis was performed using ${\chi}2$, t-test, Pearson's correlation, regression analysis and path analysis. The results are as follows. First, there is a significant difference between university students and high school students regarding their body satisfaction, weight control experience, and self esteem. University students are more satisfied with their body, have higher self esteem, and control their weight better than high school students. Second, diet behavior shows a correlation with the degree of diet interest, weight control experience, and body satisfaction. Body satisfaction and internal control proved to be correlated with bulimia behavior, while weight control experience, obesity, and self esteem were correlated with eating control behavior. Third, the variables that showed a direct influence on diet behavior as an eating disorder are diet interest, weight control experience, body satisfaction and obesity, in that the explanatory power of the variables is 60.7% with the highest mark on obesity. The variables that showed effects on bulimia are body satisfaction and internal control with an explanatory power of 2.8%. Indirect variables effecting bulimia include objects, diet interest, body satisfaction, and self esteem. The variable with a direct influence on eating control behavior was self esteem with and explanatory power of 4%, whereas the variables of objects, diet interest, body satisfaction, weight control experience, and internal control were all indirectly correlated with eating control behavior.

A stratified sampling method is generally used with a sample selected using the same sample weight in each stratum in order to improve the accuracy of the sampling survey estimation. However, the weight should be adjusted to reflect the response rate if the response rate is affected by the value of the variable of interest. It may be also more effective to adjust the weights by subdividing the stratum rather than using the same weight if the variable of interest has a linear relationship with the continuous auxiliary variables. In this study, we propose a method to increase the accuracy of estimation using an informative sampling design technique when the response rate is an exponential function of the variable of interest and the variable of interest has a linear relationship with the auxiliary variable. Simulation results show the superiority of the proposed method.

The purpose of this study was to identify women's clothing image according to their body image. Self-administered questionnaires were used for data collection. The results were as followed: First, the body image was shown in three dimensions of care for appearance, concern about weight, and appearance attractiveness. And clothing image was shown in seven dimensions of gorgeousness, beauty, sophistication, comfort, confidence, neatness, and feminity. Second, women were segmented into interest in appearance attractiveness group, body image intermediate group, appearance & weight concern group, and body image retard group. Interest in appearance attractiveness group and appearance & weight concern group were found frequently among women in 20s and students or unmarried women, preferred for gorgeousness and feminity of clothing more, and enjoyed internet shopping. Appearance & weight concern group was heavier than interest in appearance attractiveness group. Body image intermediate group were found frequently among women of lower education, and shopped at stores. Third, younger unmarried women preferred for beauty, confidence, and feminity of clothing image and older women preferred for comfort more. Women who preferred for beauty and sophistication of clothing image shopped at internet shopping mall more frequently.
