前言月经初潮年龄是反映女性儿童少年生长发育状况的常用指标,且与生殖生理学和妇科保健有着重要的内在联系(1—2)。半个世纪以来,许多国家发现女孩月经初潮年龄存在相对提前的趋势,对此,Tanner曾于1962、1966及1975年多次做过论述,他报导:在过去的一百年中,欧洲许多国家的月经初潮年龄提前了2～4年,平均每十年提前3～4月。Vlastovsky(1966)。Harper和Collins(1972)发现生长发育长期加速的趋势(3)。我国是一个人口众多的发展中国家。关于我国女孩一般人群月经初潮的年龄过去有过不少报道。如Westbrook C.H.早在1934年调查了上海309名大、中学生,报告平均初潮
Preface Menarche age is a common indicator of the growth and development of female children and adolescents, and has an important relationship with reproductive physiology and gynecological health (1-2). For more than half a century, many countries have found that girls have a relatively early age of menarche. In this regard, Tanner made numerous remarks in 1962, 1966 and 1975 and reported that in the past 100 years many European countries Of the menarche age 2 to 4 years ahead of schedule, an average of every 10 years in advance 3 to 4 months. Vlastovsky (1966). Harper and Collins (1972) found a long-term acceleration of growth and development (3). My country is a developing country with a large population. There have been quite a few reports on the age of menarche in our country’s general population. Such as Westbrook C.H. as early as 1934 survey of 309 large and middle school students in Shanghai, the average reported menarche
