In March 1980 a cross-sectional study of the pubertal developmental of a sample of Stockholm schoolchildren was conducted. Breast development (B1-B5), pubic hair (PH1-PH5) and axillary hair (AH1-AH3) were rated in 138 girls, and genitalia development (G1-G5), pubic hair (PH1-PH5) and axillary hair (AH1-AH3) were rated in 116 boys according to the Tanner method. The girls' and the boys' ratings were done by one female and one male medically qualified expert respectively. When relating social class to age of pubertal stage no significant differences were found. Median ages for entry to successive pubertal stages as well as centiles were calculated by logistic regression. Girls were somewhat earlier in their breast and pubic hair development than Stockholm girls investigated in earlier studies; however, somewhat later in their development of axillary hair. The boys entered G2 earlier than boys studied in 1970 but entered G5 at exactly the same age, 15.1 years. Boys entered PH2 somewhat later than 1970 boys, but again reached PH5 at exactly the same age, 15.5 years. The present study is based on a more recent and somewhat larger sample of children drawn from a wider area of Stockholm than the earlier studies. It is further suggested that these values be used in the proposed new height and weight reference values for youth in Sweden.
1980年3月，对斯德哥尔摩市一些学童的青春期发育情况进行了一项横断面研究。按照坦纳方法，对138名女孩的乳房发育（B1 - B5）、阴毛（PH1 - PH5）和腋毛（AH1 - AH3）进行了评级；对116名男孩的生殖器发育（G1 - G5）、阴毛（PH1 - PH5）和腋毛（AH1 - AH3）进行了评级。女孩和男孩的评级分别由一名具备医学资质的女性专家和一名男性专家完成。在将社会阶层与青春期阶段年龄相关联时，未发现显著差异。通过逻辑回归计算了进入连续青春期阶段的中位年龄以及百分位数。女孩在乳房和阴毛发育方面比早期研究中调查的斯德哥尔摩女孩略早；然而，在腋毛发育方面则略晚。男孩进入G2阶段的时间比1970年研究的男孩更早，但进入G5阶段的年龄完全相同，为15.1岁。男孩进入PH2阶段的时间比1970年的男孩略晚，但同样在15.5岁时达到PH5阶段。本研究基于比早期研究更新且样本量稍大的儿童样本，这些儿童来自斯德哥尔摩更广泛的区域。进一步建议将这些数值用于瑞典拟议的新的青少年身高和体重参考值中。
