Open publisher page 5 citations

Abstract

Variations in the age at the menarche during the period 1835-1983 were examined on the basis of reassessments of earlier Danish data and the authors own investigations. A continuous decrease in the age at the menarche totalling 3 years was found from 17.4 years in 1835 to 14.4 years in 1945. A continued drop although at a somewhat slower rate was observed during the period 1950-1983 that is from 13 3/4 to 13 years. (summary in ENG) (EXCERPT)
