The study examined BMIs, physical strength, activities, and the attitudes and behavior toward weight control among 7,968 Korean students{2,435 5th graders from elementary schools(ESs), 2,524 2nd graders from middle schools(MSs), 2,739 2nd graders from high schools(HSs)} nationwide. Compared to the 1987 data, there were increases of height(3-6cm) and weight(3-8kg), but decreases of physical strength and exercise. Lack of 'regular exercise' among girls from MSs and HSs and higher proportion of time spent on watching TV and using a computer for elementary schoolers were particularly noticeable. Proportions of students who were satisfied with their body weight were 49% for ESs, 35% for MSs, and 29% for HSs. There was no relationship between subjective and objective evaluations of body weight. Diet rather than exercise was more frequently chosen as a method of weight control. Compared to boys, girls showed stronger association between the amount of exercise and the subjective body weight in MSs and HSs, however this association was not found for the subjects from HSs. Values for the 50th percentile of BMI of boys and girls were 18.4 and 17.7 for ESs, 19.9 and 20.1for MSs, and 21.4 and 20.6 for HSs. In MSs and HSs, boys with BMI between 15th to 85th percentiles were physically stronger than those whose BMIs were lower than 15th kor higher than 85th percentiles. For the other groups, there was a trend of a positive relationship between BMI and physical strength. Based on the analyses of BMI and physical strength, this study suggests 22 and 21 for upper grades in ESs, 24 and 23 for MSs, and 27 and 25 for HSs as the respective cut off points of BMI for weight control n boys and girls. A need for implementing nutrition education program focused on weight control is also suggested.

In America, where obesity rate ranks no.1 in the world, the plus size market is rapidly expanding with various American brands adding plus size lines in a way to diversify their products. As obesity is expanding throughout the younger generation, the necessity to develop products according to different characteristics of body shape that can fulfill the needs of young plus size consumers is being emphasized. In this study of young plus size, our focus is on providing wider spectrum of design choices for consumers by analyzing different body shapes, categorizing them, and then identifying the differences of design among them. More specifically, the object of this study is to analyze the elements that differentiate the designs from each other by virtually trying out the same item on avatars of various body shapes. Thus, we can identify the elements that needs to be differentiated according to different body shapes after implementing virtual fitting program on plus size shapes that are rather difficult considering the reality of domestic fashion companies. In this way, we are able to provide fundamental data for American plus size fashion market and design development for Korean fashion companies that are under way of entering or planning to enter the American market. Furthermore, this will demonstrate the actual details of the designs that will eventually help the development of specialized product for the globalization of Korean fashion industry.

Objectives : The aim of this study was to investigate the relationship between the contributions of macronutrients to the total energy intakes and Body Mass Indices (BMI, $kg/m^2$) of Korean women. Methods : We used dietary records data from 115 healthy Korean women, ages 20 and over, who completed four 3-day dietary records between February 2003 and March 2004. For the calculation of nutrients we used a dietary assessment program developed by the Korean Nutritional Society. Macronutrient intakes were estimated by averaging individual total daily intakes in four 3-day dietary records. Subjects were categorized into three Body Mass Index (BMI) groups : underweight (BMI < 20), normal (20 $\leq$ BMI < 25), and overweight (BMI $\geq$ 25) group. Results : The total energy intakes were not different among the three BMI groups. Similarly, other macronutrient intakes such as protein, fat, carbohydrate, vegetable protein, animal protein, saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids were not different. From the multivariate nutrient density model, substituting polyunsaturated fatty acid for carbohydrate was positively associated with BMI in women aged 20 to 49 ($\beta=2.31$, p<0.01). In women aged 50 and over, substituting animal protein for carbohydrate was positively associated with BMI ($\beta=0.549$, p=0.04). Conclusions : No single macronutrient was associated with BMI when all subjects were combined. However, when stratified by age, polyunsaturated fatty acid intake in younger women, and animal protein intake in older women, were positively associated with BMI. In the future, we recommend a larger study to confirm these results.

Tea derived from the leaves and buds of Camellia sinensis (Theaceae) is consumed worldwide. Green tea contains various components with specific health-promoting effects, and is believed to exert protective effects against diseases including cancer, diabetes and hepatitis, as well as obesity. Of the various tea components, the polyphenol catechins have been the subject of extensive investigation and among the catechins, (-)-epigallocatechin gallate has the strongest bioactivity in most cases. Our research group has postulated that hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ are targets of green tea constituents including (-)-epigallocatechin gallate for their anti-diabetes, anti-obesity, and anti-hepatitis effects, respectively. Published papers were reviewed to determine whether the observed changes in these factors can be correlated with anti-cancer effects of green tea. Two major action mechanisms of (-)-epigallocatechin gallate have been proposed; one associated with its anti-oxidative properties and the other with its pro-oxidative activity. When reactive oxygen species are assumed to be involved, our findings that (-)-epigallocatechin gallate downregulated hepatocyte nuclear factor-$4{\alpha}$, sterol regulatory element-binding proteins, and tumor necrosis factor-${\alpha}$ may explain the anti-cancer effect of green tea as well. However, further studies are required to elucidate which determinant directs (-)-epigallocatechin gallate action as an anti-oxidant or a pro-oxidant for favorable activity.

This study is designed for improving wearing styles for middle-aged women who are in unsatisfactory body types and also providing the basic information about the suitable clothing designs for them. This study focuses on what kinds of body types they perceive, what the differences are between the perception of their body types and the real ones, and how the actual clothing styles can be affected by those perceived body types. This study is based on the survey of the perception of body types, the clothing styles, and the satisfaction level of body cathexis, while measuring body size of each person responded. The data were analyzed by Mean, ANOVA, Duncan-test of SPSS Win. (ver 10.1)program. The results are as follows: 1. The perception of their body types can be categorized into three clusters, the obesity, the arm & leg obesity, the slender. 2. By and large, Middle-aged women perceive their body types exactly what they we. However, they show a relatively subjective view on the upper arm girth, ankle girth, and arm length 3. The abdomen is at the lowest satisfactory part in body cathexis for the entire groups responded, and there are some differences among the perception of their body types in whole body silhouette and trunk. 4. Middle-aged women who perceive themselves as a bit slender show a tendency of having tight and revealing clothing styles, while the obese who perceived themselves wouldn't take them as appropriate dresses.

This study was conducted to investigate whether there were any differences in the body image perception, dietary behavior and maternal dietary guidance between an obese group (“OG”) and a normal weight group (“NWG”), and furthermore, to provide basic informations for comprehensive educational programs for obese children. For this purpose, the questionnaire method was used. The subjects were 1,501 elementary school children, in the 4th to the 6th grades in Seoul, Busan, Daegu, Gwangju, and Andong, and their mothers (1,459). The percentage of the children who misperceive their body image was higher among the girls (30.4%) than the boys (22.6%) The average scores for balanced dietary behavior as assessed by the children was higher in the OG than in NWG; the average scores for dietary control as assessed by their mothers was higher in the NWG than in the OG. The scores for dietary behavior as assessed by the children was different from those as assessed by their mothers. Assuming that the mothers would give more correct and balanced answers, the development of a reliable questionnaire for dietary behavior that could be more accurately answered by the children is necessary. Maternal dietary guidance for dietary control was more frequently given in the OG as compared with the NWG and more frequently in girls as compared with boys ; while that for balanced diet was more in the NWG as compared with the OG. The worse the mothers estimate of the dietary behavior for their children, the more they tried to guide their children in dietary behavior. It is recommended that the children should be taught to correctly recognize the degree of their obesity, and receive the appropriate educational program accordingly, including the maternal dietary guidance.

Objectives : This study aims to confirm the importance of behavior habit and exercise, especially leg exercise in obese. Methods : Out of 2247 people, we divided 1125 people in normal group(BMI<25) and 122 people in obese group($BMI{\geq}25$). We measured each arm, leg, abdomen muscle circumference and right and left water difference using BLA. We Investigated whether ratio of leg muscle circumference to arm and abdomen has differences by statistics between each groups. And analyzed correlation with BMI. We also investigated right and left water distribution difference of two group's limbs and the correlation with BMI. Statistical analysis was performed by using SPSS program. Results : 1. In obese group, ratio of leg muscle circumference to arm and abdomen is significantly lower than normal group(P<0.001). 2. Ratio of leg muscle circumference to arm and abdomen were negatively correlated with BMI(r-0.461, r=0.462, P<0.001). And partial correlation coefficient controlled for age and sex is -0.528, -0.632(P<0.001). 3. In the case of women, there was right and left water distribution difference as statistical in leg. In the case of Obese, the difference is serious. Conclusions : These results suggest that exercise and activity of lower limbs is more needed in the field of obesity treatment and prevention.
