This study was to investigate the body perception and dietary attitude of adolescents in relation to self-esteem. Total of 1,030 middle school students in Bucheon were participated. Data were collected from July 14 to 21, 2008. by questionnaire, and analyzed by the SPSS V. 12.0 program. The research findings were summarized as that there was considerable mismatch between perceived body shapes and actual obesity status of the subjects, 52% of the boys, 36% of the girls, and 43% of the total participants, which indicated that perception of own body shapes was distorted. The girls and obese group tended to be more unsatisfied with their body weights than boys and underweight group, respectively. The dietary attitude scores were higher in boys than girls in all obesity groups, with the obese girls the lowest score. There were differences in self-esteem scores among the obesity groups with the underweight group the highest and the obese group the lowest. Self-esteem scores of boys were higher than girls in all 4 obesity groups. The body perception and dietary attitude were correlated with self-esteem in both boys and girls. It is shown that the more negative perception on their body shape, and the worse dietary attitude they had, the lower self-esteem both the boys and girls had.

This study aims to examine the effects of a 12-week compound exercise program (aerobic exercise+weight training) on obese middle school girls' leptin and insulin before and after the exercise. This is achieved by dividing obese middle school girls whose body fat percentage is over 30% into a compound exercise group (n=20) and a control group (n=20) and conducting comparative analysis on them.After the Shapiro-Wilk normality test of the variables, a two-sample t-test was performed to see if the variables have the same mean between the compound exercise and control groups. A paired t-test was also performed to see if the changes in the variables before and after the compound exercise program were statistically significant. For all the statistical analysis, the significance level was set at ${\alpha}=0.05$. The results of this study showed the leptin and insulin levels in the combined exercise group had been significantly decreased. The regular 12 weeks of combined exercise is considered to have a positive impact on leptin and insulin levels in obese schoolgirls.

This study was conducted to investigate the relationship among pereption of obesity, experience of weight control control and satisfaction with body image in adolescence. The subjects were 221 high school students(91 boys, 130 grils), aged 16.7 years living in a rural area. To determine the perception of obesity, knowledge about obesity, belidfs about obese people, and attitudes towards obese people were measured. The results were as follows: There was high correlation between beliefs about obese people and attitudes toward obese people. When the perception of obesity was compared by sex, girls had significantly more accurate knowledge, stronger beliefs that obesity couldn't be controlled by oneself, the higher the eating disturbance score was. It also appeared that BMI was positively correlated with the positive attitude towards obese people.

The purpose of this study was to compare the growth development between age-matched 51 postmenarcheal girls (mean age 153.1$\pm$5.8 month) who were rapidly maturing and 51 premenarcheal girls (mean age 153.1$\pm$5.7 month) who were slowly maturing. Anthropometirc measurements were taken for height, body weight, body fat(%), waist and hip circumferences of subjects. These measurements of menarcheal girls were significantly higher than those of nonmenarcheal girls. There was no significant difference in BMI distribution between two groups. However, 43.2% and 20.0% respectively in the menarcheal and nonmenarcheal girls had body fat levels of 30% or above. There were significant differences in the anthropometric measurements during past 4 years from 3rd grade elementary school to present. The greatest difference between the two groups were the amount and the rate of increased height and body weight from age 9 to 10. Among menarcheal girls, height, body weight, BMI, and Röhrer index were positively related to the onset of menarche. Distinctively, there was a stronger relationship between age at menarche and anthropometric measurements when the girls were 5th grade elementary school children. These findings support that during childhood and puberty, obese girls grow faster and have earlier menarche. Furthermore, the importance of prevention of obesity was recognized in order to accelerate growth of height among the girls by delaying the age of menarche.

Purpose: This study aims to investigate gender differences in the association between depressive symptoms and weight, weight perception, and body satisfaction among Korean adolescents. Methods: A secondary data analysis was performed on data from 33,374 adolescents who participated in the 2015 Adolescent Health Behavior Online Survey. They were classified as underweight, normal weight, or overweight/obese; weight perception was classified into perception of being underweight, normal weight, or overweight/obese; and weight satisfaction into desire to gain weight, satisfied, and desire to lose weight. Results: Among boys, perception of being underweight (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.07~1.35) and desire to gain weight (AOR: 1.45, 95% CI: 1.30~1.62) were associated with depression. Among girls, perception of being overweight or obese (AOR: 1.18, 95% CI: 1.07~1.29) and a desire to lose weight (AOR: 1.30, 95% CI: 1.18~1.42) were associated with depression. Conclusion: Gender differences were observed in the association between weight perception and depression in adolescents. The perception of being underweight among boys and the perception of being overweight/overweight among girls were associated with depression. Thus, gender-specific intervention programs to correct weight perception and weight satisfaction are needed in order to relieve depressive symptoms in adolescents.

The aim of this study is to develop upper bodice pattern for obese girls aged 10~12 by using 3D virtual garment simulation system. The criteria for subjects in this study were girls who had over 1.46 of the R$\ddot{o}$hrer Index. A total of 229 schoolgirls who met these criteria were enrolled. The results of this study are as follows: First, by using 3D virtual garment simulation, new upper bodice pattern considered obese-schoolgirls was development. The basic numerical formula were as follows ; bust girth B/2+4.5, armhole depth B/4-1, waist girth W/4+0.5+dart amount, front chest width B/6+2, back width B/6+2, neck width B/12-0.5 and neck depth B/12+0.5. Second, armhole darts were added to compensate the loose amount of front armhole and dart manipulation was used to ensure a better appearance on armhole in the design. The dart side line was modified concavely to help cover the protruding stomach. Curved lines on the armhole were significantly relieved using dart manipulation and the darts side line was modified concavely to reduce the tightness around the front waist darts. Third, according to the results of the new upper bodice pattern's appearance evaluation, it estimated more highly than existing pattern in silhouette and ease amount, confirming that new upper bodice pattern was appropriate for the obese-schoolgirls. This study is expected to serve as one of important basic data for ensuing studies that may utilize 3D virtual garment simulation system with 2D patterns.

Objectives : As obese children have been increased, the interest in the impact of obesity on growth also have been increased. This study is to examine relations between obesity and skeletal maturity by analyzing body compositions and bone age. Methods : Subjects were composed of 233 children from 6 years to 17 years of age, without any other diseases related to growth, who visited the department of pediatrics, OO oriental medicine hospital and measured their body composition (body mass index, body fat ratio, fitness score) and bone age. Results : 1. As body mass index was increased, the skeletal maturity significantly was also increased. 2. As the mean of bone maturity was increased, the BMI was increased from the underweight type to the normal type to the overweight type; the bone maturity was increased as the fat ratio was increased from the normal type to the obese type to the excessively obese type; and the bone maturity was higher in the weak, obese type than the normal type when classified according to the Fitness Score. 3. The bone maturity of the overweight group in the BMI classification and excessively obese group in the fat ratio classification significantly were increased. 4. Skeletal maturity significantly was increased in children who developed secondary sexual character. 5. The significance of obesity causing increase of the skeletal maturity was higher in boys than in girls. 6. Only in the case of children without development of secondary sexual character, obesity caused an significant increases in the skeletal maturity. Conclusions : Obesity could cause the increase of skeletal maturity, and the obesity could affect more to the boys than girls and more to the children than teenagers.

Two hundred sixty six children were retrospectively surveyed from first to fifth grade to find out the status of obesity during four years. The obesity index was gained by height and weight data from student's health file and the data about eating behaviors and weight control behaviors, etc. were collected by questionnaires. Children assigned to one of the following groups : underweight, normal, overweight and obese. The results were as follows ; 1. Obese children were 18.6%(n=27) of boys and 10.8%(n=13) of girls at fifth grade. 2. Twenty eight children among forty obese children at fifth grade were also overweight or obese at first grade, and the other twelve was normal. 3. Breakfast skipping rate was significantly high among underweight and obese group of boys(p<0.01).The most children(87.6%) had prejudice for special foods. 4. The rate of agreement between obesity index and self recognition of body image was 60.7% in boys and 63.6% in girls. 5. Forty two point five percent of children have ever tried weight control as exercise(35.7%), reducing sugars and snacks(27%), fasting(23.8%), avoiding fatty foods(12.7%), taking diet food or drug(0.8%). In conclusion, the prevalence of children obesity is gradually increasing and children tried weight control without right guidances. In order to prevent progress into adulthood obesity, nutrition education should be followed with school foodservice including the right perception for obesity, proper weight control and eating behavior modification.

There may be some problems in size fitness for ready-made-clothes purchasers with Obese body shape. The purpose of this study was to improve the wearing comfort of Junior-High School Girls' slacks by setting grading points and developing grading rules proper to the obesity. The subjects in this study was over 23 kg/m2 of the BMI. The subjects were 124 Junior-High School Girls of 12 to 14 year-old. The results of this study are as follows: (1) The size intervals of waist girth and hip girth were 3 cm and 4 cm respectively. The sizing system, which had frequencies more than 5%, was classified 8 cases. The majority segment is 76-97 size accounting for the 11.29% of subjects. (2) The measurements on 8 size from two groups after drawing slacks pattern on them revealed that the changed values of slacks front and back on the grading point marked are differ, indicating that it is needed to apply body shape. (3) The evaluation on the appearance for wearing slacks showed relatively high score, indicating that the grading between sizes within each group was effective. The studies on the body size distribution on each obesity pattern and on the setting size system reflecting characteristics of each body shape should be performed continuously.

This study was designed to evaluate food habits, anthropometry and obesity of 252 children(136 boys, 116 girls) aged $2{\sim}6$ years old. The anthropometric indices were measured and food habits were surveyed. Average food habit score was 11.7/20.0 in boys and 11.8/20.0 in girls. It was found that 60.3% of the subjects belonged to fair score group(7-13) in food habits, while subjects in poor (0-6) and in excellent (14-20) were 30.6% and 9.1% respectively. There was no significant difference in food habits score between boys and girls. The food habits score tended to be higher as the mother's education level, total family income, number of siblings were increased. The mean height, weight and chest circumference of the subjects were much higher than the Korean standards. Evaluating the obesity by weight for height, 77.8% subjects was normal, 4.0% was underweight and 18.3% was obese. Underweight children did not seem to enjoy their meals and ate too slowly compared to normal or obese children. Therefore they needed to promote food habits by good nutritional education.
