跟踪一个国家儿童青春期发育的长期趋势对于社会和公共卫生是重要的。尽管在过去的半个世纪里，对美国儿童的可比研究在很大程度上是缺乏的，但关于女孩的现有数据，特别是关于初潮的数据，表明性成熟提前的趋势仍在继续，种族差异也很明显，非洲裔美国女孩比白色女孩发育得早。关于男孩的数据虽然不太可靠，但表明他们可能也开始更早成熟。需要更多关于男孩的研究，并采用可靠的方法。早期的发展可能并不健康，并可能表明需要进一步研究和解决的环境问题。
Tracking secular trends in the pubertal development of a country's children is important for social and public health reasons. Although comparable studies are largely lacking for US children over the last half century, existing data on girls, particularly that for menarche, indicate that the trend for earlier sexual maturatin has continued and that racial differences are significant, with African-American girls developing earlier than white girls. Data on boys, though less reliable, suggest that they may be beginning maturation earlier as well. More studies on boys with reliable methodologies are needed. Earlier development may not be healthy and may indicate environmental problems that need to be further researched and addressed.
