Objectives: The object of this study was to determine the relationship between body mass index (BMI) and early menarche in adolescent girls in Seoul. Methods: A retrospective study was conducted with 144 middle school students in Seoul who provided informed consent. We measured their body composition, and used the questionnaire survey method for data collection from November to December 2008. Past elemental body composition data were collected from elementary school health records of first year of middle school. Results: The early menarcheal group was taller and heavier than the late menarcheal group (p<0.05 from 8-12 years old). The body fat percentage (%), BMI were higher in the early menarcheal girls than the late-menarcheal girls (p<0.05, age at 13). In the result of multiple logistic regression, the BMI at the age of 8 and 9 was associated with early menarche after adjusting for birth weight, breast feeding and age at menarche of the mother (BMI at the age of 8: p for trend=0.01, BMI at the age of 9: p for trend=0.04). An increase in BMI from 7 to 8 year was associated with early menarche after adjusting for birth weight, breast feeding, age at menarche of the mother (p for trend=0.048). Conclusions: The BMI at the age of 8 and 9 was associated with the early menarche of girls and increase in BMI from 7 to 8 year was associated with the early menarche of girls. These results suggest that BMI and increase in BMI before menarche cause early menarche. Although this study does not represent all Korean adolescent girls, it is one of the few studies that have investigated the temporal relationship between BMI and early menarche.

Purpose: This study was performed to identify the difference in attitudes and knowledge between high school and college girls regarding sexual education. Method: Data was collected from questionnaires given to 99 high school girls and 110 college girls in Seoul and Kyunggi-do. Data was analyzed using the SPSS 12.0 program. Result: In middle school, the time given to sexual education influenced the students present knowledge of sexual education. The sources of sex education were friends, seniors and mass media. The score for sexual knowledge in high school girls was 12.78 and for college girls 24.19. The field that obtained the highest score in territorial sexual knowledge was 'reproductive physiology' in the high school girls. There was little awareness of venereal disease, AIDS, contraception. Sexual attitudes among college girls was more open than that of high school girls. There was a positive correlation between sexual knowledge and attitudes(r=.535, p<.001). The significant difference of items were residence and sexual experience(p<.001). Conclusion: This study was shown that realistic knowledge teaching of venereal diseases, contraception and AIDS should be included in planning of sexual education programs. Specially, the groups had sexual experience and college girls in the dormitory will need more specific teaching.

The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.

Objective: Middle school girls who belonged to the concerned group in their school assessment were treated by sandplay for relieving their emotional and behavioral difficulties. The purpose of this study was to explore the change of the internal world of the girls through sandplay. Methods: Analytical psychology and sandplay theories were used for this exploration, especially Turner's (2005) content themes in sandplay. The participants were four first-grade girls. Pre-test measures, a 12-session sandplay program, and post-test measures were administered. Results: For the first girl, the initial phase was 1-6 (time trip), the intermediate phase was 7-9 (seeking for an inner island), and the final phase was 10-12 (seeking for a real stone). For the second girl, the initial phase was 1-5 (my heart was like cold weather), the intermediate phase was 6-10 (fallen, sick, and risen), and the final phase was 11-12 (trophy given to me). For the third girl, the initial phase was 1-5 (seeking for oasis), the intermediate phase was 6-10 (difficult trip for climbing with camel), and the final phase was 11-12 (discovering oasis). For the fourth girl, the initial phase was 1-3 (an island drowning shortly ), the intermediate phase was 4-10 (my unknowable mind), and the final phase was 11-12 (a tree growing well). Conclusion: This study showed psychological phenomena in the sandplay of four girls such as opposites and the union of masculinity and femininity as they explored their own identity. Drawing tests and counselling objects indicated positive changes; thus, these findings support the effectiveness of sandplay therapy for transforming the psyche of middle school girls.

The purpose of this study was to suggest strategies for effective food allergen labeling in order to prevent food allergies in school meal service. Food allergy experience, eating behavior, and perceptions of food allergen labeling in school meal service were surveyed and compared according to the food allergy experiences of middle school girls in Incheon. Seventy-eight students (17% of total subjects) experienced food allergies. For eating behaviors, students with food allergy experience had significantly higher scores for using nutritional knowledge in their life than inexperienced subjects. For the perception of food allergen labeling in school meal service, girls who had experienced food allergies more often checked labeling of school meals for allergenic foods than those who had no experience of food allergies (P<0.001). The most desirable method for displaying allergenic foods was an indication of the allergenic food name among students who had experienced food allergies and allergenic food number of the current method for students who had not experienced food allergies (P<0.001). Students who had not experienced food allergies showed significantly lower interest in food allergen labeling than subjects who had experienced food allergies (P<0.001). For the importance score of information items in nutrition labeling, allergenic food score was significantly higher in students who had experienced food allergies (3.9 vs. 3.4 points, P<0.001). These results indicate that students who have experienced food allergies are more interested in food allergen labeling of school meals and that they are more aware. Efforts to improve labeling method such as directly labeling allergenic food name and a more visible indication are required for efficient utilization of food allergen labeling in school meal service.

Objectives: This study was conducted to examine the satisfaction of school cafeterias among the surveyed group at two middle schools located in Seoul. Methods: 574 out of 600 middle school students in Seoul (95.7%) completed the study. Results: Satisfaction rate of school meals was significantly higher among girls (73.2%) compared to boys (45.1%). The reasons for satisfaction factors of school meals were with the taste of school meals (55.1%), menu (19.3%), nutrition (14.2%), and food hygiene safety (7.0%). Students who had a double-income family, well-educated mother and higher happiness in their life reported a higher satisfaction with school meals. Both boys and girls who consumed milk frequently showed significantly higher satisfaction with school meals. Factors that were related to satisfaction of school meals were food temperature, the amount of food (especially among boys). Variety in the menu and food distribution speed were less related to the satisfaction of meals. In the case of girls, waiting time, food distribution speed were more important to them while the kindness of school staff was a less important factor. Improvements that were needed to increase the satisfaction for the school lunch meals, from the most important to least important were as follows: variety of meals (36.6%), food distribution speed waiting time (24.6%), taste of food (15.7%), amount of food (7.7%), hygienic management (5.1%), food quality (4.7%), kindness (3.0%), temperature of the food (2.8%). Students preferred to broadcast on campus and cooking practice for the dietary education.
