The menarcheal age of Korean women has been rapidly decreasing for the last 50 years, and the average menarcheal age of women born in the 1990s is approaching 12.6 years. In addition, interest in early puberty has been increasing recently owing to the rapid increase in precocious puberty. Generally, out of concern for short stature and early menarche, idiopathic central precocious puberty in female adolescents is treated with gonadotropin-releasing hormone analogs. Studies to date have described the association between early menarche and psychosocial problems such as delinquency and risky sexual behavior, as well as physical health problems such as obesity, diabetes, cardiovascular diseases, and breast cancer throughout the lifespan of women. However, the pathophysiological mechanism underlying this association has not been clarified thus far. In this article, we review and discuss the existing literature to describe the current understanding of the effects of early menarche on the physical and psychosocial health of adolescent girls and adult women.

The purpose of this article was to get hold of adolescent's needs for sex knowledge and to reveal their understanding of sex. These results may be applied to the sex education and counselling for adolescent. The participants of study were 267 students (females, 144 ; males, 123) who were the first and second grade form 1 middle and 2 high schools. They were asked to describe 3 questions that they wanted to know or to learn about sex. Their questions about sex were total 779(girls, subtotal 456, mean 3.2, boys, subtotal 323, mean, 2.6). These questions categorized to 9 items by content analysis. The items were ‘sexual drive, behavior and tendency(229, 29.4%)’ , ‘anatomy and physiology of reproductive system(140, 18.0%)’, ‘reproduction(131, 16.8%)’, ‘concept of sex(31, 4.0%)’, ‘acquaintance between the other sexes(17, 2.2%)’, and ‘the others(9, 1.2%)’ in order of frequency. The most frequent item that the student want to know or team about sex was ‘sexual drive, behavior and tendency’ except girls of sophomore in middle school. There were several features in participants' needs for sex knowledge as respects of the understanding of sex- biological sex, gender, and sexuality. The prominent feature in knowledge need of bio logical sex was that the participants had the interests according to their biological sex. They had the negative attitude to the phenomenons (ex, menstruation and pregnancy, phimosiectomy, etc) that they experienced or would experience due to their biological sex. A part of them asked the questions based the misconceptions and used the slangs or ‘××’, ect. to name the male or female genitalia. The male students wanted to know the female genitalia. The participants' understanding of gender reflected the sexism of our society, but they didn't accept and had doubts about the dual, hierarchical structure of that. The students, especially female seemed to be powerless to the harms of the sexual violence. Girls had much interest in their appearances and complained to our sexual culture that women comforted and served men. The participants had the dual perspective that the sexuality as respects of physiologic phenomenon was considered as natural but that as related to heterosexuals was as negative. And they deemed that men's sexual drive was stronger than women's and was difficult or was not able to be inhibited. They had much interests in homosexuality but reflected the negative attitude to that in our society. Adolescent felt wonder why the expressions of sexuality of adult were permitted but theirs were not. Lastly, a part of boys substituted querying the sexuality of animals for asking that of human. Maybe it was because of the embarrassment to talk about human's sexuality directly. The teenaged participants understood that the sex had not only the biological meanings but also the sociocultural meanings. They regarded the sex as natural and wanted to know it, but they had conceptions that it was difficult and embarrass to talk about it openly and directly.

In recent years, adolescent issues including smoking, drinking, drug abuse, juvenile delinquency, deviant sexual behavior, mental health problems, high suicide rate, juvenile delinquency and absence without due notice, etc are emerging as serious social problems and the debate on these controversial issues is heating up. The previous studies on adolescent health behavior and social juvenile delinquency such as run-away from home and absence without due notice have been conducted mostly by cause analysis utilizing social demographic factors or biological factors. In other words, the main factors analyzed were demographic and economic factors or parent's educational level, etc, which were the fixed environmental ones that were unable to cause the change in the health behavior. Accordingly, the purpose of this study is to analyze factors which are changeable and fixable among the factors influencing the adolescent's health behavior and misconducts and, eventually influencing factors which can be used as the basis to establish health policies and health promotion program to reduce the health risk behavior and misconducts of adolescents. The study subjects were selected by dividing senior high school student in Seoul by region and through random sampling. The 890 subjects were selected from 10 schools including the preparatory school, vocational schools and institutional schools. The duration of the study was for July 1-5, 1997 for the first survey and the second one, for August 25-September 10. Regarding the analysis method, the SAS program was used. The adoptablity of theoretical model was tested through covariance structural analysis utilizing PC-LISREL 8.12 Program. The major findings of the study are as follows: As a result of establishing the model of factors influencing health behavior and juvenile delinquency, in case of male students as the health behavior self-efficacy, education level of fathers, economic level, self-control and the health interest of parent were higher, students were more likely to practice the health promoting behavior. Juvenile delinquency and health risk behavior were prevalent among those with the less shyness, the lower health behavior self-efficacy, lower self-control, lower self-assertiveness, lower economic level. The self-control was the most powerful factor. In case of female students, those with higher health behavior self-efficacy were more likely to practice the health promoting behavior whereas those with lower health behavior self-efficacy, lower self-control, lower self- assertiveness, less shyness were more likely to practice health risk behavior and juvenile delinquency. In case of prep schools, those with higher health behavior self-efficacy and better perceived health status were more likely to practice the health promoting behavior while those with less shyness, lower health behavior self-efficacy and lower academic achievement were more likely to engage in health risk behavior and juvenile delinquency. In case of vocational schools, as health behavior self-efficacy and economic level were higher, the practice rate of health promoting behavior was higher. As the self-control, shyness, self-assertiveness, health behavior self-efficacy were lower, the rate of health risk behavior and juvenile delinquency were higher. In case of social institutional schools, as, the health behavior self-efficacy, social support and economic level, health interest of parents were higher, the rate of health promoting behavior were higher. As the self-control, shyness, self-assertiveness, health behavior self-efficacy and social support were lower, the rate of health risk behavior and juvenile delinquency were higher. So the health promoting behavior was positively related to the health behavior self-efficacy, health interest of parents, social support, education level of fathers, level of perceived health status, economic level. The health risk behavior and juvenile delinquency were higher with the lower health behavior self-efficacy, self-control and self-assertiveness, lower health locus control, less shyness and loneliness, lower economic level and academic achievement. In conclusion, the health risk behavior and juvenile delinquency can be reduced by enhancing self-control, self-assertiveness, health behavior self-efficacy and social support. According to the final model drawn by connecting health behavior and juvenile delinquency, the reduction of health risk behavior can greatly contribute to decreasing social juvenile delinquency as the process of juvenile delinquency was extended from common behaviors to problem behaviors and further into juvenile delinquency.
