项目摘要

Puberty on early adolescence is a period of pronounced biological, psychological, and social changes. The main purpose of our study is to examine how biology and psychological factors interact to affect the development of sexuality in females' puberty. The present study aims to investigate the sexual development in japanese 73,309females, from 10years to 15years old. The menarche stands as our primary indicator of the onset of sexual maturity in females. The mean menarcheal age of japanese female has been estimate by probit analysis from status qeo data. The data have been collected at random from schools in all 47prefectures in Japan during the February in 1997. The mean menarcheal age in the total sample was the lowest on the records for Europe and the USA,it was 12year and 2.0month, with a S.D.of 1year and 1.2month.In Japan, the secular trend or accerelation to earlier sexual maturation stopped from 1977 to 1987 around the 12.5years from our past research. But the new seular trend to earlier sexual maturation in Japan began from our new research. In the 47prefetures, the most lowest mean age at menarche was 11year and 11.1month of the Okinawa prefecture. In contrast with Okinawa prefecture, the highest mean age at menarche was 12year and 4.8month of the Shiga prefecture. There were local difference in the development of japanese females. And the mean age at menarch in Japan are thought to decrease to 12.0year from now on.The pubertal change relates to times of breakfast per week, frequecies of speaking with parents, and self sexual identity from the analysis of our research. In coclusion, it can be seen that females change psychologically and behaviorally with the changes of puberty.

青春期早期是生理、心理和社会发生显著变化的时期。我们研究的主要目的是研究生理和心理因素如何相互作用影响女性青春期的性发育。本研究旨在调查日本10岁至15岁的73,309名女性的性发育情况。月经初潮是女性性成熟开始的主要指标。根据日本女性月经初潮状况资料，采用概率分析法估计了日本女性月经初潮的平均年龄。这些数据是在1997年2月从日本所有47个县的学校随机收集的。总样本的平均月经初潮年龄是欧洲和美国记录中最低的，为12岁和2.0个月，标准差为1年和1.2个月。在日本，加速性成熟的长期趋势从1977年到1987年停止，大约是我们过去研究的12.5年。但日本性成熟提前的新趋势是从我们的新研究开始的。在47个县中，平均初潮年龄最低的是冲绳县，为11岁零11.1个月。与冲绳县相比，滋贺县初潮平均年龄最高，为12岁4.8个月。日本女性的发育存在地方差异。从现在开始，日本月经初潮的平均年龄将降至12.0岁。从我们的研究分析来看，青春期的变化与每周吃早餐的次数、与父母交谈的频率以及自我性别认同有关。综上所述，随着青春期的变化，女性的心理和行为也会发生变化。
