项目摘要

The overall purpose of our study is to examine how biology and psychological factors interact to affect the development of sexualty in females' adolescence. The present study aims to investigate the sexual development in Japanese 62,275females, from 10years to 15years old. The menarche stands as our primary indicator of the onset of sexual matuirty in females. The mean menarcheal age of Japanese female has been estimated by probit analysis. The data have been collected at random from schools in all 47prefectures during the February in1992. The mean menarcheal age in the total sample was the lowest on the records for Europe and the USA : 12year and 3.7month, with a S.D.of 1year and 0.1month. In the 47prefectures, the most lowest mean age at menarche was 12years and 0.1month of the Okinawa prefecture. Females in Okinawa prefecture grow most rapidly and tend to make a denial of self sexual identity. In Okinawa prefecture, the interplay of biology and the social environment in shaping the development of sexuality is apparent. In the total sample, increases in menarcheal experience contribute to explaining sexual identity. Pubertal development and its social interpretation have additional effects in putting females at high risk of identity cofusion. The hormonal changes of puberty may exert strong influence on the personalities of adolescents. Preliminary analysis suggests that the personality effects of menarche may disappear in late adolescent. Conclusionaly, it can be seen that we have a lot to learn about the sexual development of adolescent and how pubertal development, menarche, and social process affect it.

本研究旨在探讨生理与心理因素如何交互作用，影响女性青春期性征的发展。本研究旨在调查日本62，275名10 - 15岁女性的性发育。月经初潮是女性性成熟的主要标志。日本女性的平均初潮年龄已被估计的概率分析。资料是1992年2月在全国47个都道府县的学校中随机收集的。在欧洲和美国的记录中，总样本的平均初潮年龄最低：12岁零3.7个月，SD为1岁零0.1个月。在47个都道府县中，平均初潮年龄最低的是冲绳县，为12岁零0.1个月。冲绳县女性发育最快，且倾向于否定自我性别认同。在冲绳县，生物学和社会环境在塑造性发展方面的相互作用是显而易见的。在总样本中，增加月经初潮的经验有助于解释性别认同。青春期发展及其社会解释在使女性处于身份融合的高风险中具有额外的影响。青春期的荷尔蒙变化可能对青少年的性格产生很大的影响。初步分析表明，月经初潮的人格效应可能在青春期后期消失。总之，我们可以看到，我们有很多了解青春期的性发展，以及如何青春期发展，初潮，和社会过程的影响。
