项目摘要

The overall purpose of our study is to examine how biology and psychosocial factors interact to affect the development in puberty. The present study aims to investigate the sexual and psychological development in 73,309 Japanese females, from 10years to 15years old. The menarche stands as our primary indicator of the onset of sexual maturity. Each mean menarcheal age of Japanese females has been estimated by probit analysis from status quo data.Once the secular trend of Japanese for earlier appearance of menarche extinguished in 1980s. But the mean menarcheal age in Japan is decreasing at present. From our data, the new secular trend in sexual maturity is cotinuing in Japan. Specially, the mean menarcheal age of Okinawa prefecture is under12years old. And the development of the females in Okinawa were outstanding in psychosocial and biological points. It may be said, that the rich interplay of biological and psychosocial influences on development is especially prominent in Okinawa.These facts lead to the coclusion that the context of development are changing in Japan. Our research found that the parent-child relationship can affect the time of puberty in female. With negative relationship the mean menarcheal age tends to decrease. And, those who eat breakfast less frequently the mean menarcheal age tends to decrease. Then the development of feminity can affect the time of puberty. Negative sexual identity tends to decrease the time of puberty.The secular trend has been attributed to general improvements in health and nutrition. Such changes, however, can be markedly affected by psychosocial stress through a general decline in health. In conclusion, it can been seen that the change of puberty affects the psychosocial development and vice versa the psychosocial factors affect the time of puberty.

我们研究的总体目的是考察生物和心理社会因素如何相互作用来影响青春期的发展。本研究旨在调查73,309名10岁至15岁日本女性的性发育和心理发育。月经初潮是我们性成熟开始的主要指标。通过对现状数据的概率分析，估算了日本女性的平均月经初潮年龄。日本女性月经初潮提前的长期趋势在20世纪80年代一度消退。但目前日本的月经初潮平均年龄正在下降。从我们的数据来看，性成熟这一新的长期趋势在日本仍在继续。特别是冲绳县的月经初潮平均年龄在12岁以下。冲绳女性的发展在心理、社会和生物学方面表现突出。可以说，生物和心理社会影响对发展的影响在冲绳尤为突出。这些事实导致日本的发展背景正在发生变化。我们的研究发现，亲子关系会影响女性的青春期时间。在负相关的情况下，月经初潮平均年龄呈下降趋势。而且，那些不经常吃早餐的人的平均月经初潮年龄往往会降低。那么，女性气质的发育会影响青春期的时间。消极的性别认同往往会缩短青春期的时间。这一长期趋势被归因于健康和营养的普遍改善。然而，这种变化可能会受到心理社会压力的显著影响，因为心理社会压力会导致健康状况普遍下降。综上所述，青春期的变化影响心理社会的发展，反之亦然，心理社会因素影响青春期的时间。
