[Age of the menarche of girls in Thessaloniki, Greece].

In 1982-1983 a total of 977 girls from Thessaloniki has been investigated for their menarcheal ages, using the retrospective and the status quo methods. 565 of these girls aged between 11 and 18.5 years (age classes 1964-1972) were found to menstruate. The mean menarcheal age amounts to 12.0 years. The results are compared with corresponding data from literature. They confirm a clear secular trend for the menarcheal age in Greek population.
