Purpose: This study investigated the predictors of Sexually Transmitted Infections (STI) among female teenagers in Korea who have had intercourse at least once. Methods: This study is based on the 12th Korea Youth Behavior Web-based Survey conducted in April 2016. Data were collected from 798 middle schools and high schools nationwide in Korea and 65,528 students participated. Among the participants, the subjects of this study were 537 female high school students (Grade 10~12). The data were analyzed through complex samples multiple logistic regression using SPSS statistics 22. Results: Among the 537 female adolescents, 11.9% replied they had experienced STI. The predictors of STI among the subjects were 'age at first intercourse' and 'sexual intercourse after drinking'. The risk of STI was lower in the middle (OR=0.26, 95% CI=0.10~0.64) and high school (OR=0.11, 95% CI=0.04~0.27) age groups than those who had their first sexual intercourse at an elementary school age. The sexual intercourse after drinking group had a higher risk of STI, compared to the no sexual relation after drinking group (OR=2.54, 95% CI=1.28~5.07). Conclusion: Practical sex education programs should begin from the elementary stage in order to protect more female adolescents from STI. In addition, sex education including an alcohol prevention program should be considered to lower STI among female adolescents.

The purpose of this study is to examine the effect of female adolescents' rejection sensitivity, impulsivity and guilt on their binge eating behavior. Questionnaires on rejection sensitivity, impulsivity, guilt and binge eating behavior were administered to 607 female adolescents in Changwon and Ulsan. Of 572 collected copies, 402 were deemed valid and statistically analyzed through frequency analysis, mean and standard deviation, t-test, Pearson's correlation analysis, multiple regression analysis and stepwise multiple regression analysis using SPSS Win 12.0. The results of the study were as follows: 1) School type was found to make a significant difference in rejection sensitivity, overall impulsivity, guilt and binge eating behavior; however, its influence was not significant on the sub-factors of impulsivity: motor impulsivity, unplanned impulsivity and cognitive impulsivity. 2) For female middle school students, rejection anger sensitivity, rejection depression sensitivity and motor impulsivity were found to have a significant influence on binge eating behavior for both middle school and high school girls. Guilt, however, was found to be influential for female high school students only. 3) Impulsivity was found to have a partial mediating effect on the relationship between female adolescents' rejection sensitivity and binge eating behavior.

The purpose of this study was to classify female students' somatotypes, to investigate the relationship between five somatotypes obtained from anthropometric measurements and to examine the relationship between the spinal deformity and somatotypes. The subjects for anthropometric measurements were 844 female middle and high school students. The data were analyzed by cluster analysis, correspondence analysis, Duncan test, and T-test. The results were as follows. Cluster analysis on the factors extracted from directly measured items classified subjects into five types (middle height and a little slim type (39.6%), low height and a little slim type (13.1%), middle height and a little fat type (18.0%), tall and very fat type (7.7%), and very tall and standard type (21.6%). In examining the relationship between the normal people and those of the spinal deformity, the normal showed higher mean value in almost all the items of the girth, the depth, and the length. High school students had more spinal deformity in number than middle school students. The degree of deformity was higher in the right spinal deformity than in the left spinal deformity as the age increased. In terms of the distribution of the spinal deformity classified by the somatotype, Type 1 (middle height and a little slim type) and Type 5 (very tall and standard type) appeared the highest.

Weight reduction behavior is common among adolescent girls. The present study examined the status of weight reduction behavior and factors affecting the behavioral intention of weight reduction using the Health Belief Model (HBM) for female middle school students by weight category. Survey data was collected from three girl's middle schools in Gyeongju, Korea. A total of 299 female middle school students participated in this study. The questionnaire had questions about general characteristics, weight reduction behavior, and variables of HBM (perceived threat, perceived benefits, perceived barriers, cues to action, self-efficacy in dietary life and exercise, and behavioral intention of weight reduction). Descriptive statistics, Chi-square tests, ANOVA, and multiple regression analysis were applied to analyze the variables. A higher percentage of students in the overweight group attempted weight reduction than those in the underweight and the normal weight groups (P < 0.001). Among students who had attempted weight reduction, 73% tried diet therapy, while 78% tried exercise. Students in the normal and overweight groups showed significantly higher threat (P < 0.01) and cues to action (P < 0.001) than those in the underweight group. As for perceived benefits, barriers, and self-efficacy in dietary life and exercise, there were no significant differences among weight groups. Students in the overweight group showed the strongest intention of weight reduction and there were significant differences among the three weight groups (P < 0.001). Perceive threat (P < 0.01), cues to action (P < 0.001), and perceived self-efficacy (P < 0.01) were significantly associated to behavioral intention of weight reduction for all respondents. For the underweight group, perceived threat (P < 0.05) and perceived self-efficacy (P < 0.01) were the significant variables. For the overweight group, cue to action was the significant variable (P < 0.05).

Proper nutrient intakes and physical fitness focus one's attention on health promotion. This study was conducted to investigate nutrient intakes and physical fitness by BMI in middle school students. Health-related questionnaire, dietary intakes, food frequency questionnaire and physical fitness were studied. There were no significant differences in health-related questionnaire, food frequency questionnaire and physical fitness by BMI, but several nutrition intakes, preference of salty tastes and the proportion of iron deficiency of female students were significantly different by BMI. Although the female obese group (BMI 85 - 100 percentile) had decreased the proportion of iron deficiency and increased fish intake frequency than other groups, obese females did not show better physical fitmess than other groups. And the average Ca intake was below $75\%$ of Korean RDA in both male and female students. Significantly positive correlation was found between calorie intake and push-up of normal (BMI 15 - 84 percentile) male students (r = 0.29), also significantly negative correlation was found between protein intake and 50m dash of normal female students (r = 0.22). And significantly positive correlation was found between beans and bent knee sit-up of normal male students (r = 0.25), and significantly positive correlations were found between beans, meat, eggs, green & yellow vegetable and sit and reach (r = 0.20, r = 0.28, r = 0.21, r = 0.19) and significantly negative correlation was found between beans and long distance race of normal female students. Therefore, this study suggests that proper nutrition and non-obese states should be achieved for health promotion in middle school students.

The purpose of this study was to investigate if these factors affect the correlation between the female adolescent interest in appearance and appearance management behavior with self-concept and sexual maturity. To achieve this, a survey was conducted for the female students in elementary and middle school in the Seoul area. The results of this study were as follows. 1. The comparison of students' interest in appearance and appearance management behavior showed that the middle school students showed higher scores in both matters. 2. Elementary students generally held more positive self-concept, with domestic self value shown statistically high 3. Tanner Stage 2.3. the early puberty stage, for elementary school students, and Tanner Stage 3.4. the growth and development stage, for middle school students. The percentage of students who had already entered menstruating turned out to be only 33% for elementary students but 90% for middle school students. Their subjective views of sexual maturity were also different as elementary students had negative feeling when they thought their sexual maturity were maturity were earlier than their peers' while middle school students were just the opposite. 4. The study on the impact of self-concept and sexual maturity on the interest in appearance of female students in elementary and middle school showed that elementary students had a higher interest in appearance that corresponded to the lower domestic self-concept and a higher social self-concept. On the other hand, middle school students showed higher interest in appearance, corresponding to their higher social self-concept, lower domestic self-concept, more negative feeling of sexual maturity, and higher feeling of physical self-concept. The study on the impact of interest in appearance, self-concept, and sexual maturity on the appearance management behavior of elementary and middle school female students revealed that elementary students with a higher interest in appearance were more enthusiastic about appearance management. Middle school students' appearance management behavior turned out to be higher, corresponding to their higher interest in appearance, lower domestic self-concept, and higher social self-concept.

Purpose: This correlational study was performed to identify the impacts of maternal child rearing attitudes on the menstrual attitudes and the determinants of positive menstrual attitudes in female middle school students. Methods: With convenience sampling, 198 middle school female students were recruited living in one major city and its surrounding areas in Korea. Data was collected using a self administered questionnaire including menstrual attitudes and maternal child rearing attitudes from April 1 to July 15, 2008. Results: Among the Maternal child rearing attitudes, affectionate, achievement oriented and rational attitudes had positive correlations to a positive menstrual attitude, and an autonomous attitude had a negative correlation to a negative menstrual attitude. As determinants of positive menstrual attitudes, feeling of menarche, mother's response at first menstruation, and rational maternal child rearing attitudes were delineated and their explained variance for a positive menstrual attitude was 18.5%. There was no difference on menstrual attitudes by K clustering in terms of maternal child rearing attitudes. Conclusion: These results support the critical role of the mother. Especially desirable maternal child rearing attitudes in relation to a positive menstrual attitude would be affectionate, achievement oriented and rational for early adolescent girls. In further studies, considerations are needed for menstruation related education and research for early adolescents and active involvement of the mother & daughter together.
