Height changes in Germany   posted by Razib @ 6/19/2009 07:33:00 PM

Growth and Puberty in German Children: Is There Still a Positive Secular Trend?:
In Germany, as elsewhere in northern Europe, the upward secular trend in height is slowing (ca. 2 cm/decade up to the mid-20th century, currently less than 1 cm/decade), and the age at menarche has stabilized at just under 13 years. It remains an open question whether the observed slowing will merely be temporary, or whether it indeed represents the near-attainment of an endpoint owing to relatively stable environmental conditions.
