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.

Purpose: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. Methods: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). Results: At the school level, the average school body mass index (BMI, $kg/m^2$) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI ($kg/m^2$), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. Conclusion: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

This study investigates the wearing conditions and satisfaction level of middle school boys' uniforms. The subjects for the survey were 626 male students from 9 middle schools in Seoul. Data were analyzed using the SPSS 14.0 program. The results of this study are as follows; 1) When purchasing school uniforms, students considered the comfort and the fit important. Student considered importantly the shoulder width of jacket, the shirt length and the sleeve length of shirt, and the pant length and the pant width of pants. 2) Most of students purchased one size bigger school uniforms because they need to wear school uniforms for three years. About 80% of students had difficulties in understanding the meaning of size label, and this made it difficult to select the right size of school uniforms even if they knew their body size exactly. 3) About 10% of students repurchased school uniforms because their school uniforms did not fit any more. The periods of repurchase were the 1st grade 2nd semester and the 2nd grade 1st semester. 4) The waist circumference of pants and the pant width were evaluated larger and the pant length was evaluated to be longer (36.6% of students evaluated that the pant length was longer). Compared to 2nd grade and 3rd grade, the freshman felt that school uniforms were bigger. 5) 44.9% of students had the experience of repairing their school uniforms. The most frequent reason for repair was that the size of school uniforms did not fit well. 202 students repaired the pant length and 86.1% of them reduced their pant length.

This study was carried out to investigate the effect of eating behavior, physical status and tendency of eating disorder on the right eating habit. The subjects of this study were 324 middle school students and 340 high school students in Osan city GyeongGi province. The average of weight and height in the middle and high school students were 48.7kg, 160.0cm and 56.8kg, 164.8cm respectively. In PIBW values, 92.9% of middle school students and 99.1% of high school students were almost close to the average. The 28.5% of high school and 21.5% of middle school students were aware of themselves as overweight. The risk of eating disorders in high school students(16.4%) were higher than that in middle school students(4.9%). Moreover, the risk of eating disorders in girls high school students(19.3%) was significantly higher than those of middle school students(5.2%) (p<0.001). The thought of food problems were realized in 57.4% of in high school students and in 39.9% of in middle school students. The intake of food group frequency, middle school students ate more fruit than high school students(p<0.01). Boys ate more frequently soy beans (p<0.05) and algae(p<0.1) than girls in high school students. The meat intake was more frequent in high school students, but the eggs and milk were more in middle school students. The boys' intakes of fish and milk were more often than the girls' in high school students. Eating disorders and food intake frequency scores were closely correlated with weights(PIBW and the gap of ideal. weight with real weight). In conclusion, the education about realizing exact healthy body shape and how to modify behavior to prevent eating disorders should be planned since junior high school. Especially in high school girls, the variety food intake education would be needed. Proper recognition of the weight is required for good food intake and for prevent eating disorders.
