随机选择的212名瑞典城市儿童的青春期发育进行了调查，作为生长和发育的前瞻性纵向研究的一部分。青春期变化的时间和模式与其他当代研究的结果一致。与其他瑞典儿童调查报告的青春期发育数据的良好一致性表明，目前的样本是当代瑞典儿童的代表。本文对第二性征的两种评估方法--临床检查和全身摄影进行了比较和对比。临床检查不太费力和消耗资源，也具有心理优势，但在男孩中应通过估计睾丸体积（睾丸体积测量法）进行补充。在女孩中，两种方法具有相似的精确度和可靠性。第一次青春期变化可能在女孩9岁之前（乳房发育）和男孩10岁之前（生殖器发育）观察到。平均而言，女孩的第一次变化比男孩早一年左右。身高峰值速度（PHV）是女孩青春期的早期事件，女孩青春期相对较晚，男孩相对较晚，平均年龄的性别差异约为2岁。在女孩中，月经初潮是一个晚期事件，总是发生在PHV之后。在13-14岁时，有些男孩和女孩还没有开始青春期发育，而另一些则已进入成年阶段。
: The pubertal development of 212 randomly selected Swedish urban children has been investigated as part of a prospective longitudinal study of growth and development. The timing and pattern of pubertal changes were in agreement with the findings in other contemporary studies. The good agreement with data on pubertal development reported in other investigations of Swedish children indicates that the present sample was representative of contemporary Swedish children. Two procedures of assessment of secondary sex characters - clinical examination and whole-body photography - have been compared and contrasted. A clinical examination is less laborious and resource-consuming and also has psychological advantages but should be supplemented in boys by the estimation of testicular volume (orchidometry). In girls the two methods have similar precision and reliability. The first pubertal changes may be observed before 9 years in girls (breast development) and before 10 years in boys (genital development). On average the first change takes place about one year earlier in girls than in boys. Peak height velocity (PHV) is an early event during puberty in girls and a relatively late event during puberty in girls and a relatively late one in boys, the sex difference in mean age being about two years. In girls, menarche is a late event, always occurring after PHV. At the age of 13-14 years some boys and girls have not yet begun theri pubertal development, while others have reached the adult stage.
