The purpose of this study was to investigate self-perception of health and body image, blood lipid profiles and nutrient intake of adolescents. The subjects were 686 adolescent boys (379 middle school students, 307 high school students) and 613 adolescent girls (272 middle school students, 341 high school students) in Incheon. This cross-sectional survey was conducted by a self-administered questionnaire. Fasting blood samples were obtained and analyzed for triglyceride, total cholesterol and LDL- and HDL-cholesterol. Nutrient intakes collected from 3 day-recalls were analyzed by the Computer Aided Nutritional Analysis Program. Statistical analysis was conducted using SPSS 10.0 program. Average age, height and weight of male middle school students were 13.8 years, 163.5cm, 56.0kg and those of male high school students were 16.5 years, 171.7cm, 64.3kg. In female, average age, height and weight of middle school students were 13.7 years, 157.1cm, 51.5kg and those of high school students were 16.6 years, 159.7cm, 56.8kg. Female middle school students perceived their health status significantly better compared to female high school students (p < 0.001). Female high school students perceived themselves significantly fatter compared to female middle school students (p < 0.05). Average TG level of female middle school students was significantly higher compared to female high school students (p < 0.01). Nutrient intakes of the male and female students except phosphorus were lower than the Korean RDA. Especially, calcium and iron intakes of male and female students were under the 65% of the Korean RDA. Therefore, proper nutrition education is required for Korean adolescents to encourage desirable food habits and maintain nutritional lipids status. (J Community Nutrition 5(1) : 3∼12, 2003)

The purpose of this study was to investigate self-esteem, body image, body cathexis and body attitude of female middle school students. A total of 298 subjects were included in this study. Subjects were classified into weight control group and a non weight control group. As a result of analyzing body shapes satisfaction was higher in the non weight control group 2.83 than in the weight control group 2.28 (p<0.001). The weight control group revealed lower body satisfaction than the non weight control group. The result of the reason for weight control was the ratio of 'weight loss' 84.6%, respectively (p<0.001). Factors impacting physical image of female middle school students were analyzed as friends (3.46), internet (3.22), and TV (3.13). Results suggest that educational program should be combined with a positive emphasis on physical image and self-esteem for female middle school students. Also, there was a high correlation between body weight and self-esteem. Results indicate that female middle school students are interested in weight loss with the wrong body image. Therefore, female middle school students should be provided with an educational approach to such issues so that they have a realistic perception of their body and form realistic values about self-esteem and body.

The subjects were 253 middle school students. The data were analyzed with SPSS win 18.0 using Cronbach's ${\alpha}$, t-test, one-way ANOVA, Scheff$\acute{e}$ test and stepwise regression. The findings showed that problematic communication with the father was the strongest factor in explaining the alienation of male middle school students. The second strongest factor was the middles school student's open communication with the mother, and the third strongest factor was the middle school student's perception of physical health. Unlike male students, open communication with the father was the strongest factor in explaining the alienation of female middle school students. Problematic communication with the mother was the second strongest factor. Perception of physical appearance was the third strongest, and perception of physical health was the fourth strongest factor.

This study analyzed Kimchi eating culture in 178 households with female middle school children located in Incheon and Seosan areas, investigated the Kimchi eating patterns of female middle school students, and also analyzed the differences in value recognition for Kimchi between mothers and their female middle school students. Results showed that 23.0% of subject households answered eat Kimchi at every meal and the main reason for eating Kimchi in most households was good for taste. Most households made their own Kimchi, and only 12.3% of households bought Kimchi. Subject households preferred hot and spicy taste (34.8%) and pleasing taste (20.2%), and 44.4% of middle school children answered as eating Kimchi at every meal, and the source for information on Kimchi was home in 51.6% and mass media in 33.7%, suggesting the lack of school education. Both mothers and their female middle school students placed high value on Kimchi for its nutritional aspect and on Kimchi from the market for its convenience. Mothers showed significantly higher value (p<0.05) on the storage aspect of Kimchi compared to their middle school students, and female middle school students showed significantly higher value (p<0.05) on the value recognition for Kimchi as an international food compared to their mothers. Also, the value for hot pepper powder was high among other additional ingredients, and both mothers and middle school students had high values for Kimchi stew among other food dishes using Kimchi, and middle school students showed higher values (p<0.001) on foreign dishes using Kimchi such as Kimchi pizza and Kimchi spaghetti compared to the mothers group. Therefore, based on these results, the development of educational programs on Kimchi is needed not only at home but also at schools, by re-emphasizing the importance of value recognition for Klmchi in our food culture.

The purposes of this study were to investigate the eating of breakfast by female middle school students in Seoul, the perception of the school breakfast program (SBP), and determine the factors affecting the intention to participate in SBP. Out of 340 questionnaires distributed to the female middle school students, 334 were returned (98.2% response rate) and 323 were analyzed. The subjects were categorized into two groups by the intention to participate in SBP. Subjects were classified as participating and non participating groups. As a result of analyzing the breakfast intake frequency, 'hardly eat' showed the highest with 18.5% in the participating group and 10.3% in non participating group, while 'eat every day' showed 38.2% in the participating group, and the highest with 65.5% in non participating group (p<0.001). For the reason for skipping breakfast, 'no time' showed the highest with 30.0% in the participating group, 'over sleep' and 'no appetite' showed the highest with 24.8% in non participating group. For the reason for not participating in SBP, 'breakfast should be eaten at home' showed the highest with 47.2% in non participating group and 'may get up early in the morning' showed the highest with 46.2% in participating group (p<0.01). To determine the factors affecting the intention to participate in SBP, logistic regression analyses were conducted for female middle school students. According to the logistic regression analysis, father's education level was independently associated with the intention to participate in SBP in female middle school students [Odds Ratios (OR) 2.38, 95% Confidence Interval (CI) 1.03~5.52]. Frequency of eating breakfast on weekdays (OR 1.36, 95% CI 1.01~1.81), Level of need for school breakfast (OR 0.52, 95% CI 0.35~0.76) and whether to approve school breakfast (OR 0.27, 95% CI 0.18~0.41) were independently associated with the intention to participate in SBP in female middle school students.
