Data on menarcheal age were collected by the status quo method on a sample of 894 schoolgirls (9-19 years of age), from the Biscay province coast (Basque Country, Spain). Logit analysis provided a mean age at menarche of 12.75 +/- 0.04 years with a standard deviation of 0.93. The result was compared with data from another previous Basque study.
