title: End of the trend? A 12-year study of age at menarche.
abstract: A 12-year study of menarchial age in all girls entering the University College of Swansea (1959-70) suggests that the downward trend in age at menarche has ceased in Britain. The turning point appears to have occurred in girls born about 1946.
