Since there are no recent data on secular changes in growth and maturation of girls from West Germany, two cross-sectional studies with equal design have been carried out in Bremerhaven, North Germany, in 1979/80 and 1989. The present paper presents the results of an analysis of changes in age at menarche based on status quo data from school girls (1979/80: 2,796; 1989: 2,223) aged between 10.0 and 18.5 years. Probit analyses show a reduction over the 10-year period from 13.30 ± 1.19 to 13.01 ± 1.21 years, while logit analyses, which fit the empirical data slightly better, show a reduction from 13.29 ± 1.21 to 13.00 ± 1.24 years.
由于目前没有关于西德女孩生长和成熟的长期变化的最新数据，1979/80年和1989年在德国北部的不来梅港进行了两项设计相同的横断面研究。本文基于10.0至18.5岁在校女生的现状数据（1979/80年：2796人；1989年：2223人），呈现了初潮年龄变化的分析结果。概率分析显示，在这10年期间，初潮年龄从13.30±1.19岁降至13.01±1.21岁，而对经验数据拟合稍好的逻辑分析则显示，初潮年龄从13.29±1.21岁降至13.00±1.24岁。
